Main Points Of Vane Pumps Management
2020年5月18日In addition to the prevention of dry rotation and overload, the prevention of suction air and excessive suction vacuum, the main points of the management of vane pumps should also pay attention to:
1. If the pump steering changes, the suction and discharge directions will also change. The vane pump has a prescribed steering, and no reverse is allowed. Because the rotor blade groove is inclined, the blade has a chamfer, the bottom of the blade communicates with the oil discharge cavity, the throttle groove on the oil distribution plate and the suction and discharge port are designed according to the predetermined steering. The reversible vane pump must be specially designed.
2. The vane pump is equipped with the oil distribution plate and the stator to be correctly positioned with positioning pins. The vane, rotor, and oil distribution plate must not be reversed. The suction area of the inner surface of the stator is most susceptible to wear. Continue to use for the discharge area.
3. Disassembly and assembly Note that the working surface is clean, and the oil should be filtered well when working.
4. If the gap of the blade in the blade groove is too large, the leakage will increase. If it is too small, the blade will not expand and contract freely, which will cause malfunction.
5. The axial clearance of the vane pump has a great influence on ηv.
1) Small pump -0.015 ～ 0.03mm
2) Medium-sized pump -0.02 ～ 0.045mm6.
The temperature and viscosity of the oil should generally not exceed 55 ° C, and the viscosity should be between 17 and 37 mm2 / s. If the viscosity is too large, oil absorption is difficult; if the viscosity is too low, leakage is serious. As pump products, vane pumps refer more to vane pumps. Almost all vane pumps refer to vane pumps.
