This design has more moving parts, but it can achieve the same function hydraulic motor maintenance, and can be easily enlarged or reduced to any size. It can be seen from a long time ago the idea of ??the use of water energy! [Edit this paragraph] Piston - piston advantage is caused by changes in the volume sealed plunger reciprocates in the cylinder to achieve the hydraulic pumps and motors repair suction and pressure oil, compared with gear pump and vane pump install hydraulic motor, the pump has many advantages. The power loss of power losses in power and efficiency (1) hydraulic pump hydraulic pump have volume loss and mechanical loss of two parts: l) Volume loss volume loss means the loss of the hydraulic pump in the flow of the hydraulic motor, hydraulic pump flow actual output always less than the theoretical flow, mainly due to the leak, the oil inside the compression pump high-pressure chamber and the suction in the suction process due to too much resistance, oil viscosity and pump speed reasons which led to higher oil not all work full seal chamber. Volume loss of the hydraulic pump volumetric efficiency, which is equal hydraulic flow ratio of actual output to its theoretical flow q qt, namely the actual pump output flow q is a hydraulic motor sales, crystal create a hydraulic (online consultation), hydraulic motors from Jinan Jing Chong Hydraulic Machinery Limited.
