Rotary vane vacuum pump troubleshooting

Rotary vane vacuum pump troubleshooting: 1, rotary vane vacuum pump vacuum is not high: (1) the pump temperature is too high: (2) If the gas was pumping high temperature, the gas should be cooled before entering the rotary vane vacuum pump Inside. B, such as inhalation of hard objects cylinder wear, repair should be replaced. (3) If the pump cooling water is not enough, should open or increase the cooling water. D, such as improper assembly, resulting in single-sided wear, check and then reload. (4) oil level is too low to sight oil line position, should add enough oil.

(12) intake filter blockage, remove the cleaning. 2, rotary vane vacuum pump motor overload: (1) rotary vane vacuum pump temperature is too high, according to 20 (1) (1) item processing. (2) Aspiration of scrap iron or other mechanical material causes one-sided wear, repair or replacement of worn parts. (3) improper assembly, resulting in single-sided wear or bite hair, repair should be reassembled. 3, rotary vane vacuum pump Other: (1) shaft end oil, seal wear or incorrect assembly, replacement or reloading.
