 3. Direct rotary vane vacuum pump as technology continues to expand in various application areas, Direct rotary vane pump demand is growing. Because of this many number of pumps, processing and assembly of the heavy workload, the price is very low, so some foreign manufacturers to establish a professional vacuum plant in China. Small domestic Direct rotary vane pump is technically had passed, the price is cheaper than abroad pump, so the domestic pump still have a competitive advantage, the key is to solve the problem of seal leakage and performance quality materials and rotary vane vacuum pump oil to ensure that direct the pump at high speed, high temperature stability and reliable performance, but also to further improve the ability of water vapor in addition to domestic Direct rotary vane pumping. 4. Roots Roots vacuum pump from foreign production situation, several large foreign companies, they each share of global sales of Roots pump Roots pump sales ratio of no more than 5%, which was a total of five 20%, Roots pump output is not, but foreign Roots pump price is much higher than domestic pump. Currently rotary vane vacuum pumps, domestic and almost all large or small, high vacuum and the vacuum system, in order to shorten the extraction time and improve production efficiency are equipped with vacuum pumps, vacuum pumps made so be sure to try to occupy the domestic market on the basis of enter the international market, so it is necessary to further reduce vibration noise Roots pump, seal leakage solve problems 2X-70 升 rotary vane vacuum pumps, improving the appearance of the pump, increase the smoothness and cleanliness of the pump. Rotary vane vacuum pump and injectors smoke: refers to rotary vane vacuum pumps in operation, smoke or exhaust port fuel injection. 1, smoke, if the pump has just started running a smoking phenomenon X-100A / B rotary vane vacuum pump, which is normal, if a long time in the smoke is not normal. The solution: smoke indicates the pump inlet estuary, including the case of pipes, valves, containers have repaired. Leak After processing, the smoke will end. Vortex 2, fuel injection, indicating a large estuary intake leak, and even exposure to atmospheric air intake. The solution: to seal pump inlet of the pump running cheap 2X-70 升 rotary vane vacuum pump, fuel injection, if not, it indicates that tainted point; exhaust valve piece is damaged, check the exhaust valve piece is damaged, replace bad exhaust valve piece.
