The working principle of powder metallurgy vane oil pump rotor.
The rotor of vane oil pump is made by powder metallurgy customization. The manufacturing technology of powder metallurgy blade oil pump rotor is: mould and process design – raw material mixing – debugging and pressing on the upper machine – continuous high temperature sintering of mesh belt furnace – two plane double end grinding – Oil Immersion Inspection package. Oil pump rotor 1
The structure of the vane pump is shown in the following figure. According to the design requirements, the vane pump is composed of 12 blades and 1 rotors. The rotor is driven by the driving shaft, and the blade is attached to the pressure indoor surface under the action of centrifugal force. Because the center of the rotor is eccentric to the center of the pressure chamber, the fuel between the blades is compressed and sent to the pump. The regulating valve regulates the outflow pressure of the oil pump according to the speed of the oil pump. The regulating valve reacts to the pressure in the pump. When the pressure of the pump’s outlet is greater than the specified value, the regulating valve opens and the excess fuel returns to the oil pump population to stabilize the fuel pressure in the low pressure oil road.
The production and processing of powder metallurgy vane pump rotor is known for its high accuracy, fast production efficiency and affordable price.
