Hydraulic System Design of Piston pump Test Bench
Abstract：This article for the P090 test piston pump, design of test bench hydraulic system. The hydraulic system needs to be done is the volumetric efficiency of the pump and the total efficiency of the test, and can be tested within the range of variation of the speed, pressure, displacement. At the same time to control fluid temperature in the appropriate range. The system consists of flushing the loop, test circuit and auxiliary circuits. The loop flushing to clean the pump before the experiment is to test loop can be divided into the voltage regulator circuit, fill oil loop control system pressure and flow is mainly used in the test, the auxiliary circuit is used to control the temperature of the hydraulic fluid and maintain oil cleaning, to ensure the normal operation of the system. The principle and method to realize power recovery for the test-bed were introduced the of the recovery was analyzed. Finally to design the integrated block and the hydraulic oil tank.
