Main parameter

Power: 160KW+5.5KW+5.5KW+1.5KW+1.5+0.8+0.75=175.55KW

Maximum pressure: 35Mpa

Flow of main system: 400L+400L+200L

Speed of hydraulic pump: 0--1500r/min ( 1000r/min is advised)

Test method

Test of hydraulic pump: the main driving motor drives the tested pump to absorb medium from the hydraulic oil tank through the filter with blocking negative pressure alarm to complete the working action, and the pressure load is increased or decreased through the proportional overflow valve at the working oil port of the tested pump. (the auxiliary oil supply pump must be started for the closed circuit pump)

Test of axial high-speed hydraulic motor: same test method to the testing of pumps. (auxiliary oil supply pump must be started)

Maximum system flow ≤ 400L / min ×two way

The maximum flow of low-pressure auxiliary system is ≤ 350L / min, and the maximum pressure of low-pressure auxiliary system is 3Mpa
