Hydraulic power unit

The main cylinder of the machine and the fixture share the same hydraulic power unit, which is equipped with the plug-in logic valve provided by American SUN company,

1) Low noise: The screw pump provided by SETTIMA company in Italy, combined with the seller's unique oil source production technology, greatly reduces the noise of the whole machine and improves the working environment of the test personnel.

SETTIMA screw pump has the following characteristics, as shown in Figure 3-3:

·        Stable pressure without pulse, rated output pressure can reach 27.5MPa.

·        The design structure eliminates the phenomenon of trapped oil, can carry higher pressure and flow, and has higher efficiency.

·        The rotor has a gentle meshing surface, which reduces noise and is very quiet.

·        High volumetric efficiency, good low-speed performance, strong medium adaptability and effective energy saving.

·        The component has high wear resistance, long service life, simple structure and easy maintenance.

2) The MOOG servo valve is used to ensure the control accuracy. The servo valve is shown in Figure 3-4. Servo valves have the following advantages:

·        Driven directly by a high driving force permanent magnet linear motor.

·        Dynamic performance is not affected by pressure, stable control.

·        Low hysteresis and high resolution: fast response and high control accuracy.

·        Low power consumption at and near hydraulic zero.

·        Standardized spool position detection signal, through which the system operation can be obtained, and the valve maintenance is very beneficial.

3) Easy installation and maintenance. The hydraulic unit adopts independent semi-open structure. The front and side of the cover are open-door structures, and the backplane can be easily disassembled for easy maintenance and component replacement.

4) Small heat, good heat dissipation effect. The unique differential pressure servo control technology significantly reduces the system heat output. Hydraulic unit adopts semi-open structure with air cooling cooling device. The cooling device can be started automatically or manually. When the temperature reaches the set temperature of the oil temperature gauge switch, the air cooler motor automatically starts, so that the system can continue to work normally under high temperature environment.

5) High filtration accuracy: the filter element of the high pressure filter is made of glass fiber filter material, which has the advantages of high filtration accuracy, large oil flow capacity, small original pressure loss, large amount of pollution, etc. Its filtration accuracy is calibrated by absolute filtration accuracy. Multiple filtration, filtration accuracy of 5μm, reduce the failure rate, improve the service life of the servo valve and oil pump.

6) Pressure overload protection function: When the pressure exceeds the rated pressure of the system, the relief valve overflows to ensure the safety of the entire system.

7) Sealing method: The hydraulic pipeline from the oil pipe to the joint are imported products, the pipeline uses high pressure hose sleeve cone sealing joint, the sealing effect is very good, and can be disassembled many times.
