Radial Plunger Pump

Hangzhou Dingteng Industrial Co.,Ltd | Updated: Sep 12, 2018

Radial plunger pump can be divided into valve distribution and shaft flow distribution two categories. The valve distribution radial plunger pump has the shortcoming of high fault rate and low efficiency. The international development of radial piston pump with axial distribution in the 1970s and 1980s overcomes the deficiency of radial piston pump with valve distribution. Due to the structure characteristics of radial pump, the radial piston pump with axial distribution is fixed, which is more shock resistant, long life and high control precision than the axial piston pump. The variable stroke of variable stroke short pump is realized by changing the eccentricity of stator under the action of variable plunger and limit plunger, while the maximum eccentricity scheduled is 5-9mm (depending on the displacement size), and the variable stroke is very short. The variable mechanism is designed to operate under high pressure and is controlled by the control valve. Therefore, the pump response speed is fast. The design of radial structure overcomes the problem of eccentric wear of slipper in axial plunger pump. So that its anti - impact capability greatly improved.
