According to the installation location can be divided into top-mounted, side-mounted and under-mounted. Mounted on the fuel tank to the pump and other equipment installed in the cover plate has a good rigidity, compact structure, the most widely used. But it can also be cast on the tank shell cooling fins to enhance heat dissipation, which increases the service life of the pump. Side-mounted fuel tank is to be installed next to the hydraulic pumps and other devices tank, pump area is great, but the installation and maintenance is very convenient, usually in the larger system flow and fuel tank capacity, especially when a tank to multiple use the oil pump. Because the side-mounted fuel tank level is higher than the pump suction port of the hydraulic pump sales, it has a better suction effect. Swash plate type axial piston pump 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 pump maintenance, and most are methods using plane assignment, so maintenance is more convenient. Oil pan is one of the key components of an axial piston pump, when the pump high-pressure oil on the one hand the working chamber of the cylinder to the oil pan pump maintenance, on the other hand with the oil film between the oil pan and cylinder block the formation of a hydraulic pressure 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.
