Working principle and application range of power unit

Date of release:2019-06-10 Author: Click:

Power units are widely used: hydraulic tools power;Instrument performance testing and calibration;Static and dynamic pressure testing of aviation accessories;Chemical reagents are injected into pipelines and reactors;Pressure test of valves, pipelines, pressure vessels and other pressure equipment;Carry out pressure test on various pressure parts of the vehicle (such as brake pump, water pump, cylinder body, pump shell, etc.);Static pressure test and leakage test (such as air conditioning) are applicable to compressor housing, heat exchangers, hydraulic hoses, hydraulic engineering components, etc.

1.Low pressure air drive, light weight, easy to maintain, easy to use and outdoor transportation.

2.High output pressure, automatic pressure compensation, long time pressure holding effect is good.

3.The installation parts adopt imported components, the product quality is good, the failure rate is low, the safety factor is high.

4.Unique handle pressure device can be operated manually or pneumatically.When not used for driving?Handle pressure can be used for accurate control of output pressure when air source is used.

5.The high pressure pump valves and pipes are made of imported 316L stainless steel and are suitable for most liquid media such as water, oil and emulsion.Working principle and application range of power unit

In the working state, the hydraulic actuator is controlled by the solenoid valve, and the system command signal starts the solenoid valve to control the oil pressure and energy release of the accumulator, so as to control the cylinder slide valve and drive the valve through the mechanical transmission mechanism to realize rapid closing, normal opening and closing and test control.High-pressure cylinders may be fixed to the stem or used directly as actuators.Excess hydraulic oil is returned to the hydraulic station, allowing the piping system to control multiple valves in parallel through a return line and a return line.The hydraulic station adopts special drive technology to control the actuators of the main steam valve and the turbine bypass system.

The hydraulic power unit mainly USES liquid flow to generate pressure.When the external lever is pressed, the mechanical energy is converted to pressure output, and after a series of pipes eventually push the piston to lift the weight, the pressure is converted to mechanical energy.In fact, there are two types of processes.The process of converting different forms of energy into one another.The hydraulic power unit controls the speed of movement by adjusting the valve.When the valve opens relatively large, more fluid enters, making the body move faster, and vice versa, slower.Thus realizes the movement speed control function.
