The Features
The main oil source adopts two sets of 160KW motors to drive the 125 displacement piston pump, the maximum pressure is 45MPa, the maximum flow rate of a single pump is 200L/min, and the piston pump adjusts the flow proportionally to achieve 0-400L/min flow adjustment. When the flow rate is less than 200L/min, only one set of pumps is opened, which has an energy-saving effect.
The main circuit adopts the design of oil return filtration, and the main function is that the oil filtered by high pressure enters the oil cylinder, and the oil from the oil cylinder returns to the oil tank through the filter, and from the reduction of the scratching of the oil cylinder, the probability of system pollution is reduced.
The radial piston pump is used to continuously suppress the pressure, the flow rate of the radial piston pump is 4L/min, the maximum is 70MPa, the proportional adjustment pressure of the proportional valve is 0-65MPa, and the atmospheric circuit and the high-pressure circuit are isolated by the ultra-high-pressure pneumatic ball valve to avoid damage to the atmospheric components by the high-pressure pressure.
With the help of a high-resolution displacement sensor, the piston moving distance is measured by the drift method to calculate the leakage in the tested cylinder. At the same time, an external metering bar is installed to measure the leakage of the tested cylinder.

Advantage :Hydraulic test bench equipment features
1. Using the imported pneumatic pump from the United States as the pressure source, the pump hydraulic pump maintenance test bench, the test pressure is high, the output pressure can be adjusted steplessly, and the boost rate can be set freely;
2, using multi-pump supply pressure, the output flow is larger, the test range is wider, can meet the pressure test requirements from the range;
3. The hydraulic test bench adopts the control system and the hydraulic pump maintenance test bench. The whole test process can be completed on the computer. The computer automatically generates the pressure and time curve, and stores various data, and the test report can be printed at any time. The test process can also be manually controlled by a push button switch;
Widely Application:
Piston pumps are widely used in high-pressure, high-flow, high-power hydraulic systems and where flow adjustment is required, such as construction machinery, mining machinery, marine machinery, transportation handling machinery, and construction machinery.
