Residue pump management points in addition to anti-dry turn and overload, anti-inhalation of air and vacuum suction too large, should also be noted: 1. Residue pump steering change, then its suction and discharge direction also change the vane pump has the specified steering, does not allow the reverse. Because the rotor slots are tilted, chamfered leaves, the bottom of the leaves and drain chamber through, with the throttle on the oil pan and suction, exhaust port is designed according to the established steering. Reversible vane pumps must be specially designed. Residual oil pump in the specific use of pay attention to a certain steering function, in the actual steering in a good control, the direction do not get anti. 2. Residual oil pump assembly with oil pan and stator with the positioning pin correct positioning, blade, rotor, with the oil pan shall not be installed anti-stator inner surface of the inhalation zone part of the most vulnerable to wear, if necessary, can be flipped to install the original inhalation zone to change Continue to use for discharge area. The residue pump consists of pump body, pump cover, shaft, gear, rotor, packing, gland and other components. The pump has belt drive and gear reducer drive two forms, can reverse the role of the shaft at both ends of the skeleton oil Sealed, equipped with oil return device in the middle to prevent air intake or oil leakage. 3. Disassembly pay attention to the work surface clean, oil should be well filtered at work. 4 blades in the leaf slots in the gap is too large will increase the leakage, too small leaves can not be free to expand and contraction, will lead to work disorders. 5. Residual pump axial clearance ηv great impact.
