Vane pump consists of flange, pump shaft, pump body, oil distribution plate, blade, pressure side plate, pump cover and rolling bearing, skeleton oil seal, O-shaped rubber seal ring, bolt (a total of 3 kinds of 9 are all hexagonal head hexagon bolts) , are referred to as bolts) and retaining rings.

The pump shaft is supported by the pump body and the bearing in the hole of the pump cover seat, and the radially uniform slot has blades which can slide along the radial direction of the groove, the inner cam of the blade casing is concentric, the rear side has a pressure side plate, and finally the pump cover is closed. .

The oil distribution plate is symmetrically opened with two oil inlets that communicate with each other and two oil pressure windows that communicate with each other. The pressure side plates (with oil pan) are symmetrically open with two oil distribution plates. The oil suction window with the window opposite and also connected to the oil port.

When the pump shaft coupled by the key power source rotates, the blade is subjected to centrifugal force, and its end is placed on the surface of the stator, that is, the inner cam (after the oil pressure is established, the bottom of the blade is also subjected to the oil pressure, which causes The end is in close contact with the inner cam surface, and the blade reciprocates in the groove under the combined action of the centrifugal force and the inner cam thrust.

The oil distribution plate is integrated with the pump body, and the front side is flanged; the two bolts of the stator and the pressure side plate are fixed on the oil distribution plate; and the positioning hole pair on the pump cover of the cylindrical head (and the positioning pin) of the side plate is fixed on the side plate After entering the positioning hole, 4 bolts are fixed on the pump body.

Corrosion-Resistance Alloy,mainly refers to ordinary stainless steel resists atmosphere and sea water corrosion such as 300 series stainless steel including 304,316L, 317L etc.; comparatively strong corrosion resistance material including austenitic stainless steel 904L, 254SMOand Dual phase steel 2205,2507 etc.; Corrosion Resistant Alloy containing Cu 20 alloy; In comparison to non-metal corrosion resistant materials, corrosion-Resistance Alloy main refers to iron alloy (resistance to corrosion); nickel alloy (Ni-Cr alloy, Ni-Cr-Mo alloy, Ni-Cu alloy and other active metal.
