Prevent the return of rotary vane vacuum pump oil pump stops when improvements

If stopping rotary vane vacuum pump , and the pump chamber communicates with an oil or exhaust valve seals, pump cover plane intake manifold, gas ballast valve, Mifengbuyan , the presence and level difference due to gravity and pump differential pressure tank with the pump chamber , the oil will be returned into the vacuum chamber in the pump chamber , the oil is sufficiently large , the oil will be returned to the intake duct , resulting in the next starting resistance, and rotor vane by force, the exhaust valve by force, starting difficulties , the impact of component life, reducing pump reliability. Therefore, we should try to prevent the return oil pump stops . The principle is to cut off the oil when the pump stops , eliminating the negative pressure pump chamber , reducing the level difference and reduce back into the oil .
Specific measures are commonly used :
1 . The exhaust valve near the oil separated from the rest of the oil , the oil level is only slightly higher than the wall .
2 Move the fuel tank and the exhaust valve on the side , in order to reduce the oil level , reducing the amount of oil .
3 seat flat to flat , valves plus stretch .
4 Ha Tinh seal sealing parts are reliable, timely replacement.
5 In addition hole in the tube , so that the oil level is only slightly higher than the inlet .
6 Set the check valve mechanism , automatically shut down into the hole when the pump stops .
7 Set the pump and auxiliary institutions , cut off the oil when the pump stops .
8 pneumatic valve mounted pump port .
9 . Loading opening containers.
