China Vacuum Pump Trading Network The most important part of vacuum pump selection is the determination of the pump type. The type of pump is mainly determined by the amount of air, vacuum or exhaust pressure required for the operation. The pump should be operated in the vicinity of the maximum vacuum or the maximum exhaust pressure. Operating in this area is not only extremely inefficient, but also unstable and prone to vibration and noise. For vacuum pumps with a high degree of vacuum, cavitation often occurs in this area, and the obvious sign of this phenomenon is noise and vibration in the pump. Cavitation can cause damage to parts such as the pump body and impeller, so that the pump cannot work. And the vacuum pump is required to operate in the high efficiency zone as much as possible, that is, in the region of critical vacuum or critical exhaust pressure. Let's take a look at the seven elements that need to be paid attention to when selecting a vacuum pump. 1. The ultimate pressure of the vacuum pump should meet the working pressure of the process. The ultimate pressure of the pump is usually chosen to be about an order of magnitude lower than the process requirements. 2. Each pump has a certain working pressure range. Therefore, the working point of the pump should be selected within this range, and it should not be allowed to work for a long time outside the allowable working pressure. 3. Under the working pressure, the vacuum pump should be able to remove all the gas generated during the vacuum equipment process. 4. The vibration generated when the vacuum pump works has no effect on the process and environment. If the process is not allowed, the pump without vibration should be selected or the anti-vibration measures should be taken. 5. Understand the composition of the gas to be pumped. The gas contains no condensable vapor, no particle dust, and no corrosiveness. When selecting a vacuum pump, you need to know the gas composition and select the appropriate pump for the pumped gas. If the gas contains steam, particulates, and corrosive gases, consider installing auxiliary equipment such as condensers, dust collectors, etc. on the inlet piping of the pump. 6. When selecting an oil-sealed vacuum pump, consider how the oil vapor (soot) discharged from the vacuum pump affects the environment. If the environment does not allow contamination, you should choose an oil-free vacuum pump or discharge the oil vapor to the outside. 7. Select the vacuum unit: When a vacuum pump cannot meet the requirements of pumping and vacuum, several pumps need to be combined to complement each other to meet the process requirements.
