Rotary disk vacuum pump troubleshooting

Rotary disk vacuum pump troubleshooting:

1, rotary vacuum pump vacuum is not high:

(1) The pump temperature is too high:

(2) If the temperature of the pumped gas is high, the gas should be cooled before entering the rotary vane vacuum pump. B. If it is worn in hard cylinder, it should be repaired and replaced.

(3) If the cooling water of the pump is not enough, the cooling water should be turned on or increased. D. If it is improperly assembled, resulting in single-sided wear, it should be checked and reloaded.

(4) If the oil level is too low to the sight glass line, add enough oil.

(5) If the air trap leaks, it must be closed.

(6) The oil deteriorates and new oil is replaced.

(7) The leakage of the rotary vane vacuum pump is mostly caused by the poor oil seal of the pump's end. At this time, the exhaust cap should be opened to check if the oil pool at B is short of oil. If there is no oil, add oil from the oil filling hole to make the oil reservoir B at Fill with oil.

(8) The spring of the rotor must be removed and replaced.

(9) The valve disc is damaged and should be replaced.

(10) The seal in the oil seal on the front plate is damaged or the rubber deteriorated and should be replaced.

(11) The rotary vane vacuum pump has a long time of use, wear and clearance increases, and the damaged parts should be repaired or replaced.

(12) The air inlet filter is clogged and removed for cleaning.

2, rotary vane vacuum pump motor overload operation:

(1) The temperature of the rotary vane vacuum pump is too high. Dispose of in accordance with item 20(1)(1).

(2) Inhalation of scrap iron or other mechanical substances causes wear on one side and should be repaired or replaced with wear parts.

(3) Improper assembly, resulting in single-sided wear or biting, should be repaired and reassembled.

3, rotary vane vacuum pump other:

(1) Oil leakage at the shaft end, seal ring wear or incorrect assembly, should be replaced or reinstalled.

(2) Drive injection, the oil level is too high, excess oil should be released, or the oil blocking devices are bad and should be readjusted or repaired.

(3) The oil leakage from the end face shall be tightened by flattening the end face because the front and rear end surfaces are not flat and the end plate is not tightened.
