Hydraulic block manifold is a very important component in the hydraulic system, its role is to control the flow of hydraulic fluid in the hydraulic system, so as to achieve the control of the actuator. As the hydraulic valve block in the work often encountered a variety of impurities, oil, oxides, etc., so it needs to be cleaned regularly to ensure that it works properly. We will detail the following aspects of cleaning hydraulic block manifolds: cleaning steps, precautions, methods, and other related aspects.
Cleaning step
Removing the hydraulic block manifold
It is first necessary to dismantle the hydraulic block manifold in the hydraulic system, taking care to record the position and connection of each component for subsequent assembly.
Cleanse
Place the dismantled hydraulic block manifold into the washing tank. Add the cleaning agent. Use a brush or spray gun to clean the surface and the inside of the hydraulic valve block. Be careful not to damage the sealing structure on the surface of the valve block during the cleaning process. Cleaning time depends on the situation, generally not less than 30 minutes.
Flushing
After cleaning, remove the hydraulic block manifold and rinse with clean water to thoroughly remove cleaning agents and impurities, etc.
Dry
Place the hydraulic block manifold in a ventilated, dry place and wait for it to dry naturally or use a dryer to dry it.
Inspections
After drying, the hydraulic block manifold is inspected to check whether there is any damage or corrosion on its surface and inside, etc. If there is any problem, it needs to be replaced or repaired in time.
Assemble and install
Assemble the cleaned hydraulic block manifolds in their original positions and connections, and replace components such as seals and oil seals with new ones.
Caveat
1. When cleaning the hydraulic block manifold, you need to empty the hydraulic oil in the system first to avoid contamination of the cleaning agent.
2. Choose the cleaning agent based on the material of the hydraulic valve block and its working environment. Different cleaning agents may have varying effects on the valve block’s surface and internal components.
3. When cleaning the hydraulic block manifold, use a special washing tank and cleaning tools, and do not mix them with other components.
4. After cleaning, dry the hydraulic valve block to prevent moisture from entering the system.
5. When assembling, position and connect the components according to their original setup. At the same time, use new seals, oil seals, and other components for replacement. This ensures that the system is sealed and operates properly.
Cleaning method
1. Mechanical cleaning method
Mechanical cleaning method is the use of mechanical equipment for cleaning methods, generally using high-pressure water guns, sandblasters and other equipment for cleaning. The method of cleaning efficiency, but will have an impact on the valve block surface and internal structure.
2. Chemical cleaning method
The chemical cleaning method uses a chemical cleaning agent to clean the hydraulic block manifold. This method can remove oxides, oil, and other contaminants from the surface and internal parts. However, you need to pay attention to the selection and use of the cleaning agents.
3. Ultrasonic cleaning method
Ultrasonic cleaning involves placing the hydraulic valve block into an ultrasonic cleaning tank. The ultrasonic vibration cleans the hydraulic valve block. This method provides better cleaning results, but the equipment cost is higher.
In summary, the hydraulic block manifold cleaning is an important part of the maintenance of the hydraulic system, the need for regular cleaning to ensure that it works properly. In the cleaning process need to pay attention to the selection and use of cleaning agents, as well as cleaning after the drying and assembly steps. At the same time, each cleaning method has its own advantages and disadvantages, so you need to select them according to the specific circumstances.
