Liquid ring and dry screw vacuum pumps are both pumps that use the principle of positive displacement but have some differences. A liquid ring pump uses fluids to create the needed vacuum, while a dry vacuum pump does not.Get more news about 2022 Dry Screw Vacuum Pump,you can vist our website!

The vacuum in dry screw pumps is created through two parallel-arranged screw rotors that rotate in opposite directions. These rotors trap the gas coming in through the inlet and deliver it to the gas discharge or pressure side. As the gas is getting compressed, there is no contact between the rotors. This does away with any need for the compression chamber to have any operating fluids or lubrication, and this is the reason for the nomenclature "dry" technology.

There is, however, an internal gearbox in dry screw pumps that does need to be lubricated. This lubricant can find its way into the pumping chamber during operations over time, and in a way making false the claim of a "dry" technology.

Liquid ring pumps have cylindrical housing that is filled partially with a sealing liquid and a shaft that has a multi-blade impeller that is placed eccentrically inside the housing. The centrifugal force created by the rotating impeller creates a liquid ring.

It is this force that causes the liquid ring to be forced up against the walls on the inside of the pumping chamber.

Because of the eccentric location of the impeller in the pumping chamber, there is a constant increase and decrease of its blades depth of entry. This helps to create an increase in impeller cell volume on the side of the inlet port, thus forming a vacuum. What happens on the discharge side, is that the blades move further into the ring of liquid, causing an increase in pressure that causes the discharge through the discharge port.

The design inherent in the liquid ring pump permits the use of various liquids to act as a sealant, and this can be oil, solvents, water, or any other liquids that are compatible with the process. Liquids remain in contact with the vapors or gases that are needed to be compressed, and as a result, the compression of the gas is almost isothermal. Depending on the conditions, discharge temperatures can be between 45 and 150 degrees Fahrenheit and remain typically controlled in any process applications. As discharge temperatures are controlled in liquid ring pumps, gases of all kinds can be passed through or condensed, and this offers a great degree of flexibility.

Screw vacuum pumps can have a constant-pitch design, that allows transportation of gas at a constant volume of discharge where the major part of the compression occurs or can have progressive pitch design, in which the vapor or gas gets compressed while it is being transported to the discharge port. In both cases, the compression is adiabatic, and no heat leaves or enters the process, and discharge temperatures can be as high as 450 degrees Fahrenheit. These high temperatures in the use of this technology lead to concerns for safety.

The Oftalmica is Romaco Macofar’s latest technology for aseptic filling of sterile eye drops. This newly launched liquid filling machine is the pharmaceutical machinery manufacturer’s answer to the growing demand for ophthalmic products with no added preservatives. Much stricter GMP regulations apply when these modern pharmaceutical formulations have to be filled under sterile conditions, and the Oftalmica fulfils them all – especially where the sterility assurance level is concerned.Get more news about Aseptic Liquid Filling Machine,you can vist our website!

The machine is therefore fitted with an oRABS barrier system (either passive or active) and can also be supplied with integrated laminar flow technology if required. The Oftalmica is moreover prepared for bio-decontamination with vaporised hydrogen peroxide (VHP). Glove ports provide full access to all critical components without having to open the doors of the liquid filling machine, meaning the permissible SAL values for cleanroom class A are reliably maintained inside the machine. This facilitates process validation and production can be resumed more quickly.
Easy handling of highly viscous, oily and foaming liquids

The Oftalmica is used to fill all kinds of liquids, including highly viscous, oily or foaming fluids. The machine can be equipped for this purpose with up to eight separately driven rotary piston pumps made of ceramic or stainless steel, which can be individually controlled on the HMI. The Oftalmica’s dosing station also enables a two-phase filling process to achieve a constant, high filling capacity while at the same time reducing the load on the pumps. This approach is especially recommended for products with poor flow properties. In addition, filling in two steps has proved successful for bottles with very small necks, because ultra-fine filling needles with a correspondingly lower flow rate are used here.

The same applies when filling foaming products whose flow rate is limited solely by their physical properties. Thanks to the two-phase filling technology, the Oftalmica by Romaco Macofar has a maximum output of up to 12,000 bottles per hour – regardless of the specifications of the liquids being filled or the dimensions of the containers. If required, the Oftalmica can also be supplied with peristaltic pumps.
Ideal for many different products, containers and closures

The Oftalmica processes a vast range of plastic and glass bottles with a filling volume of between 1 and 30 ml and can be used to apply any standard closure system. Depending on the type of closure, the machine can be configured with up to three closing stations. The lightweight plastic bottles are held on the belt by vacuum as they travel through the machine, which leads to optimal process stability. For filling, the bottles are transported to the dosing station in clusters by a walking beam transfer system. Two weighing systems ensure one hundred percent weight control both before and after filling. The empty and full bottles can be inerted on request for oxygen-sensitive products. As an option, the Oftalmica can also be utilised to fill nasal sprays or sterile injectables.

Cold extrusion is a processing method that puts the metal blank in the cold extrusion die cavity and applies pressure to the blank through the punch fixed on the press at room temperature to make the metal blank produce plastic deformation and produce parts. China has been able to cold extrude metals such as lead, tin, aluminum, copper, zinc and their alloys, low carbon steel, medium carbon steel, tool steel, low alloy steel and stainless steel, and even cold extrude bearing steel, high carbon and high aluminum alloy tool steel, high speed steel, etc. with a certain amount of deformation. In terms of extrusion equipment, China has the ability to design and manufacture extrusion presses of various tonnage. In addition to general mechanical press, hydraulic press and cold extrusion press, friction press and high-speed and high-energy equipment are successfully used for cold extrusion production.Get more news about Precision Cold Extrusion,you can vist our website!

Cold extrusion connection of reinforcement refers to the joint formed by inserting the reinforcement to be connected into the extrusion sleeve and extruding the sleeve with extrusion pliers to produce plastic deformation and close compression with the surface of ribbed reinforcement. Compared with the traditional lapping and welding technology, this technology has the advantages of stable and reliable joint quality, no environmental impact, full-time construction, good seismic resistance and low temperature resistance of the joint. The extrusion equipment produced by our factory consists of ultra-high pressure pump station, high-pressure oil pipe, extrusion pliers and die, which jointly complete the extrusion connection.

Cold extrusion technology has the characteristics of accurate size, material saving, high production efficiency, wide application and high strength. It can be divided into five extrusion methods: forward extrusion, reverse extrusion, compound extrusion, radial extrusion and forging. With the development of cold extrusion technology, cold volume die forging is sometimes classified as cold extrusion. Cold extrusion is widely used in mechanical and electrical manufacturing of automobiles, tractors, bearings, telecommunications equipment, instruments, light industries such as bicycles, sewing machines, and national defense industrial systems because of its obvious advantages.

Connectors are used to join subsections of circuits together. Usually, a connector is used where it may be desirable to disconnect the subsections at some future time: power inputs, peripheral connections, or boards which may need to be replaced.Get more news about cjt connector,you can vist our website!

Gender - The gender of a connector refers to whether it plugs in or is plugged into and is typically male or female, respectively (kids, ask your parents for a more thorough explanation). Unfortunately, there are cases where a connector may be referred to as "male" when it would appear to be female; in the examples section, we'll point a few of those out as we discuss individual component types and explain why that's the case.

Polarity - Most connectors can only be connected in one orientation. This trait is called polarity, and connectors which have some means to prevent them being connected wrong are said to be polarized, or sometimes keyed.

Contact - Contacts are the business portion of the connector. They are the metal parts which touch each other, forming an electrical connection. This is also where problems occur: the contacts can become soiled or oxidized, or the springiness required to hold the contacts together may fade with time.

Pitch - Many connectors consist of an array of contacts in a repeated pattern. The pitch of the connector is the distance from the center of one contact to the center of the next. This is important, because there are many families of contacts which look very similar but may differ in pitch, making it difficult to know that you are purchasing the right mating connector.

Mating cycles - Connectors have a finite life, and connecting and disconnecting them is what wears them out. Datasheets usually present that information in terms of mating cycles, and it varies widely from one technology to another. A USB connector may have a lifetime in the thousands or tens of thousands of cycles, while a board-to-board connector designed for use inside of consumer electronics may be limited to tens of cycles. It's important that you select a connector with a suitable life for the application.

Mount
Mount - This one has the potential for being confusing. The term "mount" can refer to several things: how the connector is mounted in use (panel mount, free-hanging, board mount), what the angle of the connector is relative to its attachment (straight or right-angle), or how it is mechanically attached (solder tab, surface mount, through hole). We'll discuss this more in the examples section for each individual connector.
Strain relief - When a connector mounts to a board or cable, the electrical connections tend to be somewhat fragile. It is typical to provide some kind of strain relief to transfer any forces acting on that connector to a more mechanically sound object than the fragile electrical connections. Again, there will be some good examples of this later on.

Tobacco is often viewed as a recession-resistant segment of the market because no matter how bad things get, smokers will typically continue smoking -- perhaps even more so. Yet because COVID-19, the disease caused by the novel coronavirus, has been found to strike smokers harder than the rest of the population, many may begin rethinking their habit in earnest. Get more news about oem wholesale snus,you can vist our website!

With Altria under fire for its investment in the much-criticized Juul Labs electronic cigarette and British American Tobacco suing Philip Morris International for patent infringement over its IQOS heat-not-burn tobacco device, snus and nicotine pouches may become the means by which smokers finally break away from cigarettes.
Snus is a moist powdered tobacco typically sold in small pouches that are stuck between the lip and gum. It was already among the fastest-growing tobacco products on the market. Sales in 2018 surged 250%, and Nielsen says it's becoming a $400 million business, accounting for 4.5% of all tobacco sales this year.

While British American Tobacco is the snus industry leader with its Camel brand, Swedish Match last year became the first company to earn a reduced-risk label from the Food and Drug Administration when eight of its General brand of snus were approved for the designation.

That should give it a big competitive advantage, but as the industry continues to evolve, it may be nicotine pouches that prove to be the real category killer.Tobacco-free and lozenge-size, nicotine pouches are quickly gaining traction with users. Swedish Match rolled out the ZYN brand nationally last year and has attracted an 87% share of the market.

It was the big splash made by Swedish Match that helped push Altria to acquire the international business of Burger Sohne for its on! brand of nicotine pouches. So worried was Altria about being left behind that it made sure it was able to start selling the pouches even before the deal closed.British American is also investing heavily in nicotine pouches. Last year it narrowed its potentially reduced-risk product portfolio to three brands: Vuse, for vapor products; glo, for heated tobacco; and Velo, for nicotine pouches (or what it calls modern oral products).

It may be coincidental to the pandemic landing here, but there has also been an increase in television advertising surrounding the Velo brand, although the tobacco giant did announce last summer it would be expanding its introduction of the brand.

As consumers self-isolate, precautions to prevent upper respiratory illness as a gateway for COVID-19 infection are rising. Smoking indoors increases risks not only to smokers, but also to those around them through secondhand smoke.

Moreover, e-cigs awoke consumers to the fact there are alternatives to tobacco for nicotine consumption, and these nicotine pouches could be the clear winner since they are arguably even safer than snus because they're tobacco-free.

The global medical device market is projected to exceed a total market size of $700 billion in 2030, according to recent estimates by GlobalData, a leading data, and analytics company. This represents an impressive recovery from the impact on this sector wrought by COVID-19.Get more news about medical device translation services,you can vist our website!

As David Magnani explained in his recent article for MedCityNews, the pandemic crippled global supply chains, delaying product deliveries and inflating the price of materials. Meanwhile, healthcare costs, regulatory challenges, and cybersecurity are growing concerns, alongside counterfeiting and imitation, recalls and lawsuits, and interdisciplinary competition.

As a provider of specialist language solutions to leading organizations in the life science field, including medical device manufacturers, DWL aims to support customers to address these seven challenges in our own way.

1. Disrupted supply chains

Like most Language Service Providers (LSPs), we rely on professional medical translators based around the world. As the pandemic struck, we needed to be sure that our network of trusted freelancers was not disrupted. To assess its resilience, we asked around 800 of those translators about the strength of their translation business and their optimism for the future. The results suggest that business was good as the COVID-19 lockdowns hit and, despite a reduction in workload for some, most respondents’ businesses were not adversely affected. Most were also confident that the need for medical translations would be sheltered from economic downturns caused by the pandemic.

2. Rising healthcare costs

When budgets become tight, it is incumbent on every supplier to help customers realize cost savings, whether through added efficiencies or strategic decision-making. From our perspective, that means harnessing the potential of technology, such as computer-assisted and machine translation, and streamlining workflows to lower costs and drive efficiencies. As a BIG Language Solutions company, DWL can also provide customers with competitive prices for patent translation and foreign filing services – in some cases, leading to a 30%+ cost saving.
3. Regulatory challenges

Translating the documentation required to commercialize medical devices can pose a unique challenge since it requires both technical and medical expertise. Device manufacturers need the support of a specialist LSP if they are to ensure their translations comply with local regulatory requirements and are delivered in time. We summarised the EU Medical Device Regulation (MDR) in our mini-video series, click here to watch the recording.

4. Cybersecurity concerns

Manufacturers are not only battling concerns about patient privacy and the protection of data stored or shared by their devices, but they also need to keep their own data and confidential documents secure. This includes sensitive information about the innovation, know-how, and intellectual property (IP) rights that underpin their technology. Any data or document shared with an external supplier adds unnecessary risk if it is not appropriately secured and controlled. We deliver peace of mind to customers by managing their translations through our proprietary LanguageVault® platform, the world’s most secure translation environment™.
5. Counterfeiting and imitators

A translation supply chain is a potential place of weakness for device manufacturers as they prepare to launch in new markets. By keeping content fully locked, LanguageVault® can also play a valuable role in helping device manufacturers guard against the IP theft and iteration that is becoming increasingly commonplace in this sector.
6. Recalls and lawsuits

The MedCityNews article suggests that a better medical device approval process in the United States would deescalate tension and safeguard producers and consumers. Recalls and lawsuits are common, it argues, because definitive medical claims may draw scrutiny from regulators, not to mention high customer expectations. In Europe, Article 7 of the EU MDR prohibits the use of text, names, trademarks, pictures, or signs that may mislead customers as to a device’s purpose, safety, or performance. For instance, including functions that the device does not have, false information regarding treatment or diagnoses, failure to inform about risks associated with the use of the device, or suggesting alternative uses for the device not covered by the conformity assessment. Language is everything in this context and translators will need to work closely with customers to ensure they deliver the appropriate level of nuance.

They come in handy in a pinch, keep all our electronics running and in general make life at home a lot easier. It’s a fact: extension cords are quite frankly a home necessity.Get more news about Extension Socket Company,you can vist our website!

Overall, yes. When used properly, extension leads are safe for use around the house. For added peace of mind, every extension cord you use should be manufactured and purchased from a trusted supplier. Likewise, if a lead is damaged in any way, it should not be used as this can make it a hazard.

No, you should never plug more than one extension cord into a power source. This also means you shouldn’t ‘daisy chain’ extension leads. By doing this, you run the risk of overloading the wall socket which can result in blowing a fuse or even an electrical fire.

Even if you haven’t noticed any of these issues, it’s a good idea to annually audit the lead extensions you have around the house. Add it to the list when you check your fire or carbon monoxide detectors! Also, you should never attempt to fix an extension cord yourself. If it’s damaged, it’s time to replace it!

Can extension leads be left on?
If you use an up-to-date extension cord properly, you shouldn’t have an issue if you leave it on the majority of the time. That being said, it is always wise to switch off sockets you aren’t using and the same goes for an extension lead that isn’t being used. Also, if you overload an extension lead and leave it on permanently, it is more likely to overheat which can cause damage to your belongings or even start a fire.

We recommend turning an extension lead off or unplugging it altogether if you won’t be home for a few days at a time or if there is nothing plugged into the extension cord. Of course, if you notice any of the issues we noted above, you should immediately turn off the cord’s power source and unplug the extension lead.
What should you not plug into an extension cord?
There are two main things that should never be plugged into an extension cord: another extension lead and major appliances. Small to large appliances can quickly overheat a lead extender which can result in damages or even a fire. Most kitchen appliances, from your fridge all the way down to your kettle or toaster, should never be used with an extension cord.

If you’re unsure if something should be plugged in via a cord extender, it’s best to play it safe. But if you must use one temporarily, be sure that the extension lead you choose is powerful enough to supply the correct amount of electricity.

If you don’t know much about OSD Audio (OSD is short for Optimal Speaker Design), it might be time to start paying attention. We were caught off guard by the clean, deep bass emanating from the $200 Nero TubeBass 10 subwoofer we reviewed last year so we wanted to see what OSD’s $600 Trevoce 12 EQ DSP could do. We were not disappointed. The subwoofer mates a 12-inch woofer with two side-facing passive radiators, app controllable DSP with 25-band parametric equalization, and an 800-watt amplifier in a manageable 15-inch cube. There are also standard crossover, volume, and phase controls but you probably won’t use them once you fire up the app.
Reviewer Al Griffin subjected the subwoofer to dual torture tests — one in a system set up for music, the other in a home theater dedicated to movie watching. The Trevoce 12 rendered the bass swells on Steven Wilson's "King Ghost" (The Future Bites) in a clean, dynamic manner and was able to convey the immense power of the deep synth-bass lines on "Valley" from The Orb's 1995 electronic album Orbus Terrarum. “I was impressed with how much of it I was hearing,” Griffin noted, adding: “I was also able to push the volume to near-uncomfortable levels without losing clarity.”

Movie time was every bit as impressive. When the plane gets hijacked and smashes into a hangar in the 2020 sci-fi action thriller Tenet, the impact was palpable, and Ludwig Göransson's droning, bass-heavy score was rendered in an appropriately dynamic manner — one that created the extreme tension the composer was no doubt going for. If you like the idea of nuanced performance from a subwoofer with an arsenal of controls that lets you really dial in the bass, the Trevoce 12 EQ DSP is well worth a look and listen.

Tipping the scales at 153 pounds and commanding well over 2 cubic feet of space, Monoprice’s new 13-inch bass beast is the latest model in its ever-expanding Monolith series and could be your last subwoofer — as long as you have the space (and budget) for it. The 13THX (our unofficial name) is a surprisingly no-frills affair featuring a tank-like custom woofer, which weighs 60 pounds on its own, a ballsy 2,000-watt (steady-state) amplifier, and an over-built triple-ported enclosure (foam plugs are provided for those who might want to experiment with different alignments).
There’s no remote control, wireless connectivity, or app-controllable auto-EQ. Instead you get a straight-up, back-to-basics super subwoofer with a standard set of crossover and other controls (including "THX" and "Extended" EQ settings) that is dead flat below 18Hz and capable of hitting 115dB SPL at 25Hz. As reviewer Daniel Kumin put it ever-so vividly, “Unless you live in a decommissioned train station or are a convicted bass-felon with an ankle-monitor, Monolith's 13THX delivers more bass than you can use. Placed and balanced with care, you can be assured you are hearing whatever bass exists on a recording, at any level you desire. Period.”
