Precautions for the use of hydraulic equipment

Time of issue:

2021-11-23

Precautions for the use of hydraulic equipment 1. Using high-precision filter, according to the requirements of electro-hydraulic servo valve for filtration accuracy, generally 5-10um 2. The material or paint of the inner wall of the fuel tank should not be changed to the pollution source of the oil all year round. The material of the fuel tank of the withholding machine control system should preferably be stainless steel. 3. After the oil tank and piping system go through a general acid treatment process, inject low-viscosity hydraulic oil or turbine oil for no-load cycle flushing. After the flushing is qualified, all the cleaning oil is discharged, and the qualified hydraulic oil is injected into the oil tank through the precision filter. 4. In order to ensure that the crimping machine control system has a better purification function during operation, it is best to add a low-pressure self-circulating cleaning circuit 5. The installation position of the electro-hydraulic servo valve is as close as possible to the hydraulic actuator, and there are as few hoses as possible between the servo valve and the actuator. These are all to improve the frequency response of the system 6. Electro-hydraulic servo valve is a precision product integrating mechanics, hydraulics and electricity. You must have relevant basic knowledge before installation and commissioning. In particular, you must read and understand product samples and instructions in detail. Pay attention to a few points; a Whether the model of the installed servo valve conforms to the design requirements, and whether the servo valve dynamic and static performance test data at the factory are complete b Whether the model and technical data of the servo amplifier meet the design requirements, and its adjustable parameters must match the servo valve used; c Check the control coil link mode of the electro-hydraulic servo valve, series, parallel or differential link mode, which one meets the design requirements d Whether the model and connection mode of the feedback sensor meet the design requirements, pay special attention to the accuracy of the sensor, which directly affects the control accuracy of the system; e Check whether the oil source pressure and stability meet the design requirements. If the system has an accumulator, check the charging pressure 7. The hydraulic cylinder used in the control system of the crimping machine should be a low-friction hydraulic cylinder, and its minimum starting pressure should be measured before installation, as the basis for checking the hydraulic cylinder in the future.
