Classification of hydraulic pumps. According to the structure, it is divided into three categories: plunger pump, gear pump and vane pump. According to whether the displacement is adjustable: quantitative pump, variable pump. According to the direction of oil discharge: one-way pump, two-way pump. According to the pressure level: low pressure

08/02/  · The contamination and wear of the pump can be controlled within the allowable range. At present, high-precision oil filters are widely used, which can greatly extend the service

2. According to the hydraulic system commonly used pump structure is divided into: gear pump, vane pump and plunger pump. Gear pump: smaller, simple structure, 

18/12/  · Classifications of hydraulic pumps. There are two main classifications of hydraulic pumps – positive-displacement pumps and non-positive-displacement pumps. Positive displacement pumps do not allow any slippage around the pumping element. This effectively means that hydraulic fluid cannot move past the pump itself unless the pump is turning.

The two major divisions are gear, vane, and piston pumps. Gear pumps can be further divided into internal and external gear pumps. Piston pumps can be divided 

Pumps in general are classified on following basis, 1) Classifications based on principle of operation Hydrostatic type pumps (Positive displacement). Hydrodynamic type pumps (Non - Positive displacement type). 2) Classification based on displacement Constant displacement pumps.Variable displacement pumps. 3) Classification based on Constructions

Hydraulic components are the basic components of hydraulic system equipment, divided into four categories: hydraulic pumps, control valves, 

A large range of design principles and configurations exists behind hydraulic pumps. Consequently, not every pump can fully meet all sets of requirements to an 

Hydraulic pump: classification. 2- Positive displacement pumps. • This type is universally used for fluid power systems. • As the name implies, 

This article mainly introduces the characteristics and classification of hydraulic components of the hydraulic system. (1) HYDRAULIC PUMP. The hydraulic pump is a mechanical energy-hydraulic energy conversion element. It is responsible for providing a hydraulic oil source that meets the requirements for the hydraulic system and is the power
