How does Manhart (Guangdong) CNC Machine Tool Co., Ltd. check for leaks in the hydraulic system of the bending machine?

To check for leaks in the hydraulic system of the bending machine, the following steps can be followed:
1. * * Observing the hydraulic system * *: Firstly, it is necessary to conduct a comprehensive observation of the hydraulic system of the bending machine, checking for any signs of leakage in various pipe joints, hydraulic cylinders, control valves, pumps, and other components. Leakage may manifest as oil droplets, oil stains, oil mist, etc.
2. * * Check pipe joints * *: Pipe joints are common locations for hydraulic system leaks. Check if the pipe joint is tight and if there is any looseness or damage. If leakage is found in the pipe joint, it should be replaced or repaired in a timely manner.
3. * * Check hydraulic cylinder * *: Hydraulic cylinder is also a common source of leakage. Check for leaks in the piston rod and cylinder body of the hydraulic cylinder. If there is a leak, it may be due to damage or aging of the seal, and it should be replaced in a timely manner.
4. * * Check control valves * *: Control valves such as directional control valves, pressure control valves, flow control valves, etc. may also leak. Check the various interfaces and sealing surfaces of the valve to see if there is any leakage.
5. * * Check the pump * *: Check the various interfaces and sealing surfaces of the hydraulic pump to see if there is any leakage. If the pump leaks, it may be due to damaged seals or worn shaft seals, which should be repaired or replaced in a timely manner.
6. * * Use instruments for testing * *: If the above methods cannot identify the leakage point, professional instruments such as particle X-ray flaw detectors, X-ray imaging machines, etc. can be used to conduct more detailed testing of the hydraulic system.
When checking for leaks, it is important to pay attention to safety and avoid direct contact with the leaked oil to prevent harm to the skin and eyes. At the same time, it is necessary to follow the operation and maintenance manual of the equipment to ensure safety and accuracy of inspections.
The above information is for reference only, and the specific inspection steps and methods may vary depending on the equipment. It is recommended to refer to the equipment’s operation and maintenance manual or consult a professional maintenance engineer before actual operation.
