Troubleshooting of 2X rotary vane vacuum pump

1, rotary vacuum pump vacuum is not high:

(1) If the pump temperature is too high, the sealing degree will drop. If the temperature of the pumped gas is high, the gas should be cooled before entering the rotary vane vacuum pump. If the external temperature is too high, cooling and ventilation are necessary to assist.

(2) If the cooling water of the pump is not enough, the cooling water should be turned on or increased.

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

(4) The gas ballast valve is not closed tightly and should be closed strictly.

(5) Vacuum oil, water or organic material, should be replaced with new oil.

(6) Rotary vane vacuum pump leakage is mostly caused by poor oil seal on the end of the pump. At this time, the exhaust cap should be opened to check whether the oil pool at B is short of oil. If there is no oil, oil should be filled from the oil filling hole to make oil sump B. Fill with oil.

(7) The spring of the blade is broken and should be removed and replaced.

(8) Valves and other accessories are damaged and should be replaced in time.

(9) Rotary vane vacuum pumps have a long time of use, wear and gaps increase, and damaged parts should be repaired or replaced.

2, rotary vane vacuum pump motor overload operation:

(1) Rotary vane vacuum pump temperature is too high.

(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 and timely adjustment.

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) Excessive oil will cause fuel injection, which should be released a little, 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.

Warning: The vacuum must not be pumped with corrosive gases, or it should be used directly and open to the atmosphere without a drying device or organic matter collection device. How to model the vacuum pump is prohibited to operate in conjunction with the atmosphere for a long time.
