High-Efficiency Technologies for Hydraulic Pumps

A hydraulic pump is a rotary machine in which a piston reciprocates by the rotation of the shaft to cause the pump to eject hydraulic fluid.
The flow of this hydraulic fluid changes in direction and pressure in a complex and rapid manner in line with the operation of the pump.
In order to enhance the efficiency of a hydraulic pump, it is necessary to improve its resistance to heat generated by the sliding motions (*) of the parts, while suppressing leakage from each sliding part.
To achieve this, we have optimized the pump structure by accurately understanding the internal behavior of the pump through utilization of our technologies including fluid analysis technology for predicting dynamic changes in the hydraulic fluid flow, mechanism analysis technology for reproducing complex motions of the parts, and high-precision measuring technology.
