The method of reducing the power loss of the hydraulic system of the construction machinery equipment.

On the one hand, the power loss of the hydraulic system will cause energy loss and reduce the total efficiency of the system. On the other hand, the lost part of the energy will be converted into heat energy, which will increase the temperature of the hydraulic oil and deteriorate the oil. Cause hydraulic equipment to malfunction.

Use and Maintenance of Hydraulic Piston Pump for Construction Machinery

The efficiency of the hydraulic system of construction machinery mainly depends on the volumetric efficiency of the hydraulic pump. When the volumetric efficiency drops to 72%, it is necessary to carry out regular maintenance, replace bearings and aging seals, and replace or repair friction pairs that exceed the fit clearance. Its performance is restored.
