Hydraulic Pump Accessories Description

The hydraulic pump is a key component of the hydraulic system, serving as its primary source of power. This pump transforms mechanical energy into hydraulic energy through a process that involves the conversion of motion into changes in the enclosed volume. When driven by a power machinery such as an engine or motor, the pump draws in oil from the hydraulic tank, compresses it into pressurized oil, and then discharges it to the actuating components. These components then manipulate the hydraulic system to perform specific functions.

The various types of hydraulic pumps include gear pumps, vane pumps, plunger pumps, and screw pumps. Each type has its unique design and operational characteristics.

Gear pumps, for instance, are known for their small size, simple structure, and relatively low cleanliness requirements. They are also less expensive. However, they have a tendency to experience uneven force distribution on the shaft, which can lead to wear and leakage.
