Brief introductionThe hydraulic test bench adopts the closed oil tank structure, which is allowed to work in the environment with dust, but pay attention to regularly cleaning the dust on the hydraulic equipment during use, so as to ensure that the hydraulic system has good heat dissipation and oil cleanlinessMain parameterPower: 160KW+5.5KW+5.5KW+1.5KW+1.5+0.8+0.75=175.55KW Maximum pressure: 35MpaFlow of main system: 400L+400L+200LSpeed of hydraulic pump: 0--1500r/min ( 1000r/min is advised) Function of the test bench It mainly tests single or double or triple open hydraulic pumps, or single closed hydraulic pumps,or axial high-speed hydraulic motor, etc.Driving mode: 160KW electric motor ( 6 pole), rotation speed: 0--1500r/min ( 1000r/min is advised) Loading mode: 1 loading for pump, through pilot relief valve and 3 loop loading method, maximum pressure is 35Mpa*2+31.5Mpa*1 - Loading for hydraulic motor:
Oil feeding mode: Low pressure oil pump oil supply: 70 L/min 0-3MPaSelf priming oil supplyHigh pressure auxiliary oil pump: 18L/min 0-31.5Mpa1# pilot pump auxiliary oil: 15L/min 0-4Mpa2# pilot pump auxiliary oil: 15L/min 0-4MpaDisplaying mode: - by meters and computer;
- Flow, temperature, and speed are displayed in digit;
- Pressure is displayed by meter and the computer reads the signal sent by the pressure sensor ;
- The oil level is directly displayed by the liquid level gauge
- Filter blockage is alarmed by red light and buzzer
Oil purification: 8-stage filtrationAnother oil pump is equipped to recover the oil in the oil groove of the platform area.Working medium: isovg46 hydraulic oilVolume of Oil: 1000 L Test items 1, Displacement test: no-load pressure test, displacement test2, Test of volume efficiency: the volume efficiency under rated operating conditions, 3. Overload test: maximum displacement of hydraulic pump or motor (high speed), nominal speed, running for 1 minutes or less under rated pressure or under the maximum pressure - External Leakage test: in the test above, check the leakage of the sealing parts.
Test accuracy(1) Pressure: accuracy ± 0.1%, measurement range 0-35mpa (part 31.5Mpa)(2) Flow: accuracy ± 0.5%, measuring range 5-400l / min(3) Speed: accuracy ± 0.5%, measuring range 0-1500r / min(4) Temperature: accuracy ± 1 ºC, measuring range - 20-100 ºCTest methodTest of hydraulic pump: the main drive motor drives the tested pump, absorbs the medium from the hydraulic oil tank through the filter with blocking negative pressure alarm, and completes the working action. At the working oil port of the tested pump, the pressure load is increased or decreased through the proportional overflow valve. (the closed circuit pump without make-up oil pump and the motor for pump condition test must start the auxiliary oil supply pump)Test of axial high-speed hydraulic motor: same to the test method of hydraulic pumps (the auxiliary oil-supply pump must be started)Hydraulic motors with balance valve(A6VE,A2FE): the loading motor (used as pump working condition at this time) performs shaft end loading test on the tested motor.Other dataMaximum system flow: ≤ 400L / min * two way + 200L / min * one wayThe maximum flow of low-pressure auxiliary system is ≤ 70L / min, and the maximum pressure of low-pressure auxiliary system is 0.2-3mpa.The flow of high-pressure auxiliary system is ≤ 18L / min, and the pressure of high-pressure auxiliary system is 1-32mpa.The maximum flow of the pilot system is ≤ 15L / min, and the maximum pressure of the pilot auxiliary system is 0-4mpa.Power requirements: AC380V 300ASensor and control power supply: DC24VThe computer automatically generates test reports, curves, and acquire data and print out the test reports..Tested components: It mainly test open hydraulic pumps, double open pumps, closed pumps, high-speed hydraulic motors, auxiliary test low-speed hydraulic motors. etc.Clockwise rotation and counterclockwise rotation Can be tested
