Maintenance and repair of vacuum pump unit

First of all, the maintenance and repair of the vacuum pump unit. First of all, the purity of the protective gas filled should not be less than 99.99%. Then, in terms of vacuum pump unit equipment, to a large extent, it is important to be careful not to use flammable, explosive and corrosive gases as a protective atmosphere.

Next, with regard to the maintenance and repair of the vacuum pump unit, the surface of the equipment and the surface of the instrument should be kept clean to a large extent. Cleaning the inner wall of the furnace shall not allow the cleaning with water or with non-vacuum oil.

Next, for the maintenance and maintenance of the vacuum pump unit, the oil-water separator on the pneumatic triples above the pneumatic system should pay attention to discharge water frequently, and the vacuum diffusion pump oil should be injected in the oil-mist device. And when the equipment is used, the voltage of the whole machine should be guaranteed in the range of 350 ~ 420 V to a large extent. The three phases need to be balanced.

In addition, we should pay attention to the regulation of the vacuum pump unit or the pressure gauge at electrical contact and the thermocouple. In other words, we should always apply the diffusion pump oil, forming a film between it and the seat, so as to prevent the leakage of the equipment. The vacuum seal sealing is not allowed to be used for a long time for each part and its flange connection. The bolts of each part should be checked regularly. When the equipment is found to be loose, it should be tightened in time.

Finally, when the vacuum pump unit is working, we should pay attention to the display on each instrument and the sound of each pump. In this way, to a large extent, it is convenient for us to find out the anomalies in time and then to find out the problems. Moreover, the use environment of vacuum pump unit, eight at below 5% relative humidity, temperature is 10 ~ 40 ℃.
