The Oil Pumps is an important part of the lubrication system and can pressurize the oil to distribute it around the engine. It is usually related to internal combustion engines. The oil pump is a type, also called hydraulic pump or submersible pump. These pumps can pressurize the hydraulic oil in the hydraulic system.

The application range of hydraulic pumps is very wide. Generally, it can be summarized as the transfer and circulation of liquids in light industry and agricultural…

The single-acting vane pump is composed of rotor, stator, vane, oil distribution plate and end cover. The inner surface of the stator is a cylindrical hole. There is an eccentricity between the rotor and the stator. The blades can slide flexibly in the slots of the rotor. Under the action of the centrifugal force during the rotation of the rotor and the pressure oil at the root of the blade, the top of the blade is attached to the inner surface of the stator, so two adjacent blades, the oil…

The double-acting vane pump not only balances the radial force acting on the rotor, runs smoothly, uniformly delivers oil, and has low noise, but because it is a double-acting pump, it increases the flow rate, so the structure is compact and the volume is small. The disadvantage of the double-acting vane pump is that the structure is more complicated, the oil absorption characteristics are poor, and it is more sensitive to oil pollution. Double-acting vane pumps are widely used in various…

The main components of the pump are the cam surface and the rotor. The rotor contains splines to drive the radial slots of the shaft. The rotor rotates inside the cam ring. Each radial slot contains a blade, which can slide freely into or out of the slot due to centrifugal force. The blade is designed to cooperate with the surface of the cam ring when the rotor rotates. The cam ring axis is offset to the drive shaft axis. When the rotor rotates, centrifugal force pushes the blades towards…
