Improve vacuum pump performance

What measures can effectively improve the performance of vacuum pump?
In our daily use of vacuum pump, with the increase of the use time, the performance of vacuum pump will be affected more or less, so what measures can effectively improve the performance of vacuum pump or even improve it? Vacuum pump performance improvement way actually has a lot of, the following we DE nair, vacuum pump network based on technology research and the accumulation of experience, summed up the following several way to improve and improve, such as pump rotation speed, the influence of vacuum pump, etc., the influence of the pump body and impeller gap familiar with master these specific content, to improve the performance of the vacuum pump, a favorable effect and the stability of the vacuum pump operation.

1. Vacuum pump inlet valve
Vacuum pump as usual is used for pumping air into vacuum state, but not all establishments are requested vacuum degree is lower, the better, but some places are request control needs in the vacuum degree of a certain range, the pump cavity pressure or vacuum pump is too low, the pump cavity will produce serious cavitation, form the vibration and noise of the pump is too large, affect the use of time, and in the environment, can properly close the regulator to stress the influence of vibration and noise, to need the vacuum degree of the request. This is a way to double the proper use of vacuum pumps.
2. Influence of coolant system of vacuum pump
Replenishment coolant must be carried out in succession. But therefore which method to stop the supply coolant, the supply coolant flow, pressure is how to determine, the ability to improve the function of vacuum pump. Affect the performance of vacuum pump. Course repeated verification invention, self-priming pump was used to stop the rehydration,, due to pump fluid in the suction chamber to stop supplies or from the impeller end stop rehydration, coolant used to start things for a long time, also is a loss of energy had certain, plus rehydration of liquid ring will happen at this time the blow is lost, also reduced the coolant to the useful power of the gas, spent part of the energy. It can give full play to the influence of the liquid ring, squeeze the vacuum pump out of the pump cavity in real time, make up for the cooling fluid out of the pump cavity in real time, smooth shaft seal and so on, and improve the running reliability, stability and effectiveness of the vacuum pump
3. Specific gas-liquid separation facilities
Gas beginning from the vacuum pump out into the primary air water respectively, and force out the gas out of the device respectively, full of ablation gas cooling fluid was shipped to the next level of low pressure gas water respectively, because of low pressure, melt in the liquid gas is released into, because the cycle of application of the cooling fluid, respectively from the lower level respectively in the liquid pressure very low, need to use booster pump for vacuum pump stop rehydration.
