Caterpillar Hydraulic Pumps

The working principle of the Caterpillar hydraulic system is as follows:
The diesel engine turns the shaft of the Caterpillar hydraulic pump, converting mechanical energy into hydraulic energy.

Hydraulic oil is delivered to Caterpillar hydraulic pumps and Caterpillar hydraulic cylinders through the Caterpillar control valve system, where it is converted into mechanical energy for rotary or reciprocating motion.

After the job is done, the hydraulic oil returns to the hydraulic tank and enters the Cat hydraulic pump. The work cycle is repeated continuously.

There are two types of heavy equipment hydraulic systems:

The positive displacement hydraulic system it operates uses hydraulic motors and hydraulic pumps operating at high pressures up to 350 MPa. The system works on the principle that the working chambers of the pump and the hydraulic motor are alternately filled with hydraulic oil and discharged under high pressure. The velocity of motion of the working fluid in such a system is very small. The main factor in the system is pressure. Positive displacement hydraulic drives are physically more compact than hydraulic drives and are more widely used.
