1、 Working principle of radial piston pump

Radial piston pump is a common hydraulic pump, which is mainly composed of five parts: pressure chamber, plunger, swing rod, rear cover, and flow regulating device. When working, the swing rod fixes the plunger on the rotor, and as the rotor rotates, a pressure difference is formed between the plunger and the pressure chamber, thereby promoting the flow of oil.
 

2、 Working principle of axial piston pump

Axial piston pump is a hydraulic pump with adjustable flow rate, which is mainly composed of four parts: bearings, axial piston components, cam mechanism, and flow control system. The internal axial plunger component can be driven by a cam to swing the plunger in the axial direction, thereby generating a pressure difference to drive liquid flow and achieve flow control.
 

3、 The difference between axial piston pump and radial piston pump
 

A. The difference in working principle: Axial piston pumps use internal axial piston components to swing in the axial direction, generating pressure differences to drive liquid flow and achieve flow control; Radial piston pumps, on the other hand, create a pressure difference between the plunger and the pressure chamber as the rotor rotates, thereby driving the flow of oil.

B. Structural differences: Axial piston pumps have a much more complex internal structure than radial piston pumps, consisting of bearings, axial piston components, cam mechanisms, and flow control systems; The radial piston pump, on the other hand, is much simpler, mainly consisting of a pressure chamber, plunger, swing rod, rear cover, and flow control device.

C. Different application ranges: Axial piston pumps are suitable for hydraulic systems with high flow requirements, such as milling machines, heat treatment equipment, etc; Radial piston pumps are usually selected as propulsion pumps for hydraulic systems when high speed and high power output are required.
