What is a cloud PBX Cloud PBX (Cloud-based Private Branch Exchange) is a virtual PBX system rooted on the internet, which automatically answers all calls and routes them to the right department or user extension. Traditionally, PBX systems are housed on-premises. These machines are big and need their own storage room. They also require significant capital investment, making them out of reach for smaller businesses. The cloud changed all that. Cloud PBX is hosted in secure, remote data centers and is delivered through the internet. It provides the same call routing and management features of an on-premises PBX without the need for expensive hardware. The cloud PBX solution is also offered as a service on flexible plans, so smaller businesses can subscribe to it instead of investing heavily on an expensive on-premises system.

What is Unified Communications Unified Communications (UC) refers to a phone system that integrates (or “unifies”) multiple communication methods within a business. Your business probably communicates in a number of ways: phone calls, video conferencing, instant messaging, email, SMS, fax – the list goes on and on. A UC solution brings together all the ways your business communicates and lets them “talk” to each other so they can work together in one system – making your business much more efficient. Modern office communications require connectivity, mobility, and unique features for a variety of users. And Unified Communications (UC) brings all of these advanced capabilities and more.

Talk about vacuum pump Water ring vacuum pump (water ring pump) is a kind of coarse vacuum pump. The limit pressure it can obtain is 2.66-9.31kpa for single-stage pump and 0.133-0.665kpa for double-stage pump. Water ring pump can also be used as compressor, it belongs to low pressure compressor, its pressure range is (1 ~ 2) x105pa gauge pressure (under specific conditions). Water ring pump is widely used in many processes of petroleum, chemical, machinery, mining, light industry, papermaking, power, metallurgy, medicine, food and other industries, municipal and agricultural sectors, such as vacuum filtration, vacuum feeding, vacuum degassing, vacuum evaporation, vacuum concentration and vacuum moisture regain, etc Flammable, explosive gas, in addition to dust, water gas can be pumped, therefore, the application of water ring pump is increasing. Water ring pump is composed of impeller, pump body, suction and exhaust disc, water ring formed by water in the inner wall of pump body, suction port, exhaust port, auxiliary exhaust valve, etc. [url=https://www.evpvacuum.com/water-ring-vacuum-pump-type.html]Water Ring Vacuum Pump[/url] [url=https://www.evpvacuum.com/dry-scroll-vacuum-pumps.html]Dry Scroll Vacuum Pump[/url] [url=https://www.antsalliance.com/]industrial vacuum pumps,vacuum furnaces[/url]

How to use screw vacuum pump Screw vacuum pump will be affected by air leakage in the process of use. Many users think that this is a quality problem of the equipment, which has been replaced by new equipment. However, the cause of air leakage is not only the quality problem, but also the front and rear covers are different? In other words, the front and rear covers of the screw vacuum pump have different axial degrees, and the result is the same as the bearing deflection. With the increase of the liquid ring temperature, the saturated vapor pressure also increases, which reduces the vacuum degree of the screw vacuum pump, but has no effect on the exhaust pressure? Tighten the connecting bolts and stuffing box of the screw vacuum pump, tighten the connection between the pipeline, instrument and other parts, or replace the gasket and stuffing. For the leakage of the screw vacuum pump, putty can also be used as a temporary remedy to make the bearing deflect, so that the impeller inclines and is installed in the pump body of the screw vacuum pump. The axial clearance of single acting pump is uneven. When the impeller rotates, the side cover must have certain friction, and the side cover and the impeller end face will be scratched. When the gas in the compression chamber passes through the increased gap, the axial gap increases, and a large amount of gas leaks into the suction chamber, thus reducing the vacuum pressure or discharge pressure of the screw vacuum pump. At this time, the bearing of screw vacuum pump must be removed for maintenance, and then installed correctly. Screw vacuum pump is a kind of pump device, which completes the suction and exhaust work produced by synchronous high-speed reverse rotation in the pump shell.

Roots vacuum unit used in vacuum metallurgy industry Roots vacuum unit is widely used in vacuum degassing, vacuum melting, liquid steel vacuum treatment, space simulation, low-density wind tunnel and other devices to extract corrosive gas in vacuum metallurgy industry. It can also be used in distillation, evaporation, drying and other production processes of chemical industry, food, medicine, motor manufacturing and other industries. When working, the pumped gas enters between the rotor and the pump body through the air inlet. At this time, a rotor and the pump body separate the gas from the air inlet, and the separated gas is sent to the exhaust port during the continuous rotation of the rotor. Space is in a closed state, therefore, there is no compression and expansion. But when the peak of the rotor turns to the edge of the exhaust port, because the pressure of the V part is lower than that of the exhaust port, in order to make the pressure in the connected volume uniform, the gas will diffuse from the exhaust port to the V area, and the diffusion direction is opposite to the rotation direction of the rotor. When the rotor rotates again, the gas at V is compressed to the exhaust port to discharge it. At this time, the other side of the rotor is connected with the air inlet to inhale the gas. When the rotor rotates continuously, the above air extraction process is repeated to continuously discharge the gas flowing in. This working process is equivalent to that the rotor space increases from a small value to a large value, and then decreases from a large value to a small value. This is the volume principle of Roots vacuum pump.
