Oil well pump is refferred as hydraulic pump or submersible pump,which pressueizes hydraulic fluid in a hydraulic system.An oil pump (internal combustion engine) is important a part of the lubrication system that pressurizes motor oil for distribution around the engine,which apply to pump oil out of wells.
Hydraulic pump are widely used in the hydraulic drive systems and it can be mainly divided into hydrostatic and hydrodynamic. Hydrostatic pump is a kind positive displacement pumps. Being distinguished form hydrostatic pump, hydrodynamic pumps can be fixed displacement, in which the displacement cannot be adjusted. At the same time, hydrodynamic pumps have a more complicated construction that allows the displacement to be adjusted in special need by the user.
The application of hydraulic pumps can be summarized as transferring and circulation of liquids within light industry and farming irrigation and pressure boosting. And it also can be applied tin cooling systems and air-conditioning systems.
And in the daily application of hydraulic pump, especially in the hydraulic installation, one pump can serve more cylinders and motors. The attendant problem however is that in that case a constant pressure system is required and the system always needs the full power. It is more economic way to solve this problem is to give each cylinder and motor its own pump.
