Generally divided into single-piston pump piston pump, horizontal piston pump, axial piston pumps and radial piston pumps. There are eccentric structures, plunger, spring, cylinder, two-way valve. Closed volume is formed between the piston and the cylinder bore. Eccentric rotation of a turn double radial pumps, piston reciprocating motion a downward movement of the suction, the upward movement of oil discharge. Oil pump volume per revolution a turn expelled called displacement, displacement is only concerned with the structural parameters of the pump. Swash plate type axial piston pump is generally used to rotate the cylinder, end assignment form. End surface of the cylinder by a double set with a metal plate and steel valve plate consisting of friction radial pump, but in most cases, a plane with the flow method, so maintenance is more convenient. Oil pan is one of the key components of an axial piston pump, single row radial pump pump, high-pressure oil on the one hand the working chamber of the cylinder to the oil pan, on the other hand with oil pan and cylinder block between The film pressure form of a hydraulic cylinder so that the cylinder away from the thrust reverser with the oil pan. Cylinder oil pan design of hydraulic compression force Fn slightly larger than the valve plate hydraulic cylinder thrust reversers on Ff, namely Fn / Ff = 1.05 ~ 1.1, the pump is working properly and to maintain a high volumetric efficiency.
