General vacuum pump has two working modes, intermittent and continuous.


The intermittent operation mode is mainly applicable to the semi-automatic vacuum packaging machine: the semi-automatic vacuum packaging machine relies on manual up and down or back and forth swing the cover, which determines that the size of the vacuum chamber should not be too large. The working mode of vacuum pump of semi-automatic vacuum packaging machine is intermittent. Only when the vacuum cover is closed, the vacuum pump will run, while the vacuum pump will not work at other times. The advantage of this control mode is to reduce power consumption and noise, while the disadvantage is that the pump has been started in a intermittent state, so there is certain wear on the pump, which requires the vacuum pump The quality of must pass the customs, customers in the purchase of vacuum packaging machine should not just look at the price, and ignore the quality of vacuum pump. If the quality of the pump is not up to standard, long-term use will lead to the phenomenon of slow vacuum pumping and poor vacuum effect.


The continuous operation mode is applicable to the automatic vacuum packaging machine: the automatic vacuum packaging machine controls the automatic swing of the cover through the air cylinder. The air cylinder provides the pressure to the vacuum cover through the vacuum pump, so the vacuum pump is always in operation, which is one of the advantages of the automatic vacuum packaging machine. In addition, the automatic vacuum packaging machine has strengthened the treatment on the plate and the whole machine frame, This is one of the reasons why the whole equipment size of the automatic vacuum packaging machine is larger than that of the ordinary vacuum packaging machine.


Gas analysis and partial pressure measurement in vacuum are usually performed by dynamic mass spectrometer. If there are solid particles in the conveyed medium, filter screen shall be added at the pump inlet: if there are ferromagnetic particles, magnetic filter shall be added.


The ambient temperature of the vacuum pump manufacturer's vacuum pump in use shall be less than 40 ℃, and the temperature rise of the motor shall not exceed 75 ℃. After the normal operation of the magnetic pump for 1000 hours, the wear of the bearing and the end face moving ring shall be removed and inspected, and the wearing parts which can not be reused shall be replaced. For the delivery liquid which is easy to precipitate and crystallize, it shall be cleaned immediately after use to drain the liquid in the pump. The vacuum pump must always be kept clean, no other objects shall be placed on the vacuum pump, and the channels around the pump shall not be blocked for better maintenance and operation.
