Introduction and advantages of rotary vane vacuum pump unit

Introduction and advantages of rotary vane vacuum pump unit

The rotary vane vacuum pump unit is a pump-based pump and a rotary vane pump is connected in series with a pre-stage pump. The rotary vane vacuum pump unit selects the rotary vane pump as the front pump, so it overcomes the shortcomings of the low pumping rate under a certain pressure when the rotary vane pump is used, and at the same time retains the Roots pump can work quickly and has the advantages of relatively large pumping rate. Because the rotary vane vacuum pump unit has compact structure, large pumping speed and small occupied area, it can replace many mechanical vacuum pumps. Therefore, the rotary vane vacuum pump unit is widely used in vacuum smelting, power capacitor, transformer vacuum heat treatment, vacuum coating equipment, pre-pumping, electric vacuum semiconductor and other industries to remove airtight

Application of vacuum pump unit

Application of vacuum pump unit

The water ring vacuum pump unit is mainly composed of roots pump and water ring pump as the front pump in series. The water ring pump selected by the vacuum pump unit is more advantageous than other vacuum pumps, because the vacuum pump unit not only overcomes the shortcomings of the pressure difference of the limit pressure of a single water ring pump (the limit pressure of the unit is greatly improved compared with the limit pressure of the water ring pump) and the low pumping rate under a certain pressure, but also retains the advantages of the Roots pump that can work quickly and have a relatively large pumping rate. It can be adapted to pump a large amount of condensable steam, especially when the gas ballast oil seal mechanical vacuum pump has insufficient ability to remove condensable steam, or the solvent used

The water ring pump selected by the water ring vacuum pump unit is more advantageous than other vacuum pumps, because it not only overcomes the disadvantages of exceeding the limit pressure difference (the limit pressure of the unit is greatly improved compared with the limit pressure of the water ring pump) when a single water ring vacuum pump is used, but also retains the advantages of the Roots pump that can work quickly and has a relatively large pumping rate. It can be adapted to pump a large amount of condensable steam, especially when the gas ballast oil seal mechanical vacuum pump has insufficient ability to remove condensable steam, or the solvent used

Several Problems Not Neglected in Vacuum System

Several Problems Not Neglected in Vacuum System

Several problems that cannot be ignored in the vacuum system: 1. When connecting vacuum components such as valves, traps, dust collectors and vacuum pumps to each other, please try to make the pump tube short and the pipe flow conduction large. The diameter of the pipe is usually not less than the diameter of the pump port. This is an important principle of system design. But at the same time, it is necessary to consider the convenience of installation and maintenance. Sometimes in order to prevent vibration and reduce noise, a mechanical pump can be installed in a pump chamber close to the vacuum chamber.

Maintenance method of water ring vacuum pump

Maintenance method of water ring vacuum pump

In combination with the characteristics of the water ring vacuum pump, the following key issues should be paid attention to when using: 1. Check the oil level frequently, if it does not meet the requirements, please adjust to meet the requirements. When the water ring vacuum pump is running, the oil level is in the center of the oil standard. The oil change period should be considered according to the actual conditions of use and whether it meets the performance requirements. Generally, when a new water ring vacuum pump pumps clean and dry gas, it is recommended to change the oil every 100 hours of operation. After no ferrous metal powder can be seen in the oil, the oil replacement cycle can be appropriately extended in the future.

The principle and advantages of water ring vacuum pump

The principle and advantages of water ring vacuum pump

The water ring vacuum pump is eccentrically installed in the pump housing with a multi-blade rotor. When it rotates, it throws the liquid onto the pump casing and forms a liquid ring concentric with the pump casing. The liquid ring and the rotor blades form a variable-volume rotary variable-volume vacuum pump.

Analysis of Carbon Steel and Aluminum Materials Used in Vacuum System Technology

Analysis of Carbon Steel and Aluminum Materials Used in Vacuum System Technology

In vacuum system technology, stainless steel is an excellent material for constructing chambers or components. Stainless steel has sufficient strength at the flange connection-even in the baking process will not affect its hardness. It can be welded to ensure its vacuum seal, and its surface has been completely passivated to provide sufficient protection for many applications.
