Development status of radial piston hydraulic motors at home and abroad

Bignozzi motors from Italy, Chamberlain motors from the UK, and Jahns and Pleige motors from Germany are typical representatives of low-speed, high-torque hydraulic motors. As some of the earliest low-speed, high-torque hydraulic motors, they have high performance, relatively compact structures, and are inexpensive. Currently, a large proportion of the world's motors are produced by these manufacturers.

What should I do if water gets into the hydraulic system? Hanzhu hydraulic motors offer some suggestions.

After 200 hours of use, the hydraulic oil of the excavator became polluted and deteriorated, appearing as a milky white, viscous substance. Preliminary judgment indicates significant water ingress into the hydraulic system. Therefore, it was decided to clean the entire hydraulic system and replace the hydraulic oil.

Han Bamboo Hydraulics tells you about the use and maintenance of engineering machinery hydraulic plunger pumps

The efficiency of a hydraulic system in engineering machinery primarily depends on the volumetric efficiency of the hydraulic pump. When the volumetric efficiency drops to 72%, routine maintenance is required, including replacing bearings and aged seals, and repairing or replacing friction pairs exceeding the allowable clearance to restore performance.
