Hydraulic pump industry definition and introduction

HHYDRAULIC PUMP

1: Definition, basic concepts

·The hydraulic pump is the power component of the hydraulic system, which is driven by the engine or the motor, inhales oil from the hydraulic tank, forms a pressure oil discharge, and sends it to the actuator. Hydraulic pump according to the structure is divided into gear pump, plunger pump, vane pump and screw pump. The working principle of the hydraulic pump is that the movement brings changes in the volume of the pump chamber, thus compressing the fluid so that the fluid has pressure energy.

2.Classification of hydraulic pumps

（1）Classified by whether the flow rate is adjustable

·metering pump

·variable pump

（2）According to the structure of hydraulic pump classification

·gear pump

·ram pump

·vane pump

3.The working principle and structural characteristics of hydraulic pump

·When a hydraulic pump operates, it creates a vacuum at the pump inlet, which forces liquid from the reservoir into the inlet line to the pump and by mechanical action delivers this liquid to the pump outlet and forces it into the hydraulic system.
