Maintenance tips and suggestions for superimposed hydraulic control check valves
1. Daily inspection and cleaning
Regular inspection:
Regularly inspect the superimposed hydraulic control check valve, focusing on the status of seals, control pistons, springs and other wearing parts.
Check whether the valve is stuck and ensure that the valve can operate normally.
Cleaning and maintenance:
Regularly clean and maintain the superimposed hydraulic control check valve to remove impurities and scale to prevent component wear and sticking.
During the cleaning process, special attention should be paid to the protection of precision components such as control pistons and springs to avoid damage.
When cleaning, special cleaning agents for hydraulic systems should be used, and corrosive, toxic or flammable cleaning agents should be avoided.
2. Part replacement and adjustment
Timely replacement of wearing parts:
If problems such as seal aging or damage, control piston wear, spring fatigue or breakage are found, the corresponding parts should be replaced in time.
When replacing parts, you should ensure that the quality of the new parts meets the equipment requirements and avoid using inferior or substandard parts.
Adjust parameters:
According to actual needs, the relevant parameters of the superimposed hydraulic control check valve are adjusted, such as spring preload, control piston stroke, etc.
When adjusting parameters, you should follow the equipment manufacturer's recommended values to avoid arbitrary adjustments that may lead to equipment performance degradation or failure.
3. Oil management
Change oil regularly:
To ensure the normal operation of the hydraulic system, the oil should be replaced regularly.
When replacing the oil, clean the entire hydraulic system to ensure the oil is clean.
Select the appropriate oil model and brand according to the equipment requirements to ensure that the oil quality meets the requirements.
Monitor oil status:
Regularly check the cleanliness, viscosity, water content and other indicators of the oil to ensure that the oil is in good condition.
If any abnormality in the oil is found, it should be replaced or processed in time to avoid damage to the equipment.
4. Precautions for use
Guaranteed control of pressure:
It must be ensured that the superimposed hydraulic control check valve has sufficient control pressure, and the control pressure is not allowed to lose pressure.
Pay attention to whether the control pressure meets the requirements for reverse opening to avoid malfunction of the hydraulic control check valve.
Reasonable selection of structure and oil drain method:
According to the position of the superimposed hydraulic control check valve in the hydraulic system or the liquid flow resistance (back pressure) after the reverse oil outlet chamber, the structure (simple or compound) and oil leakage method (internal leakage or external leakage) of the hydraulic control check valve should be reasonably selected.
The internal leakage type hydraulic control check valve is generally used in situations where there is no back pressure or the back pressure is small in the reverse oil outlet chamber; the external leakage type hydraulic control check valve can be used in situations where the back pressure in the reverse oil outlet chamber is high.
Avoid frequent fluctuations in load pressure:
Frequent and strong fluctuations in load pressure will affect synchronization accuracy and equipment stability.
Fluctuations in load pressure should be minimized to ensure normal operation of the equipment.
5. Maintenance of records and file management
Keep maintenance records:
Keep detailed records of the maintenance process of the superimposed hydraulic control check valve, including maintenance time, replacement parts, adjustment parameters and other information.
Through maintenance records, the maintenance history of equipment can be tracked and provide reference for subsequent maintenance.
Create device profile:
Create a file for each piece of equipment to record the basic information of the equipment, maintenance records, fault handling, etc.
Through equipment files, you can fully understand the operating status and maintenance needs of the equipment, and improve the efficiency and level of equipment management.
