1., the fuel tank wall material or paint should not be changed to perennial oil pollution source, hydraulic control system fuel tank material is best to use stainless steel

2., the use of high-precision filter, according to the electro-hydraulic servo valve on the filter accuracy requirements, generally 5-10um

3. tank and piping system after general acidic treatment process, low viscosity hydraulic oil or turbine oil, for no-load cycle irrigation. After cleaning, all the cleaning oil is released, and the qualified hydraulic oil is injected into the tank through the precision filter

4., in order to ensure the hydraulic control system in the operation process has better purification function, it is best to add low pressure self circulation cleaning circuit

5. the installation position of the electro-hydraulic servo valve is as close as possible to the hydraulic actuator, as much as possible between the servo valve and the actuating element, in order to improve the frequency response of the system

6. electro-hydraulic servo valve is a mechanical, hydraulic and electrical integration of precision products, installation, debugging must have relevant basic knowledge, especially to read and understand product samples and instructions. Pay attention to what time;

A servo valve installed model and design requirements are consistent, factory servo valve dynamic and static performance test data integrity

B servo amplifier model and technical data are in line with the design requirements, the adjustable parameters to match the servo valve used;

C check the electro-hydraulic servo valve control coil connection mode, series, parallel or differential link way, which meets the design requirements?

D feedback sensor model and link whether the design requirements, in particular, pay attention to the accuracy of the sensor, it directly affects the control accuracy of the system;

E check the oil source pressure and stability to meet the design requirements, and if the system has accumulators, check the inflation pressure
