What mistakes should be avoided when operating the pressure relief valve of the Road Roller?

1. Operation without stopping the machine
1. Risk: If the pressure relief valve is operated while the Road Roller is running, the hydraulic system is still under working pressure. Opening the pressure relief valve at this time may cause high-pressure oil to spray out instantly, causing personal injury and equipment damage. At the same time, operation without stopping the machine may cause the equipment to suddenly lose power, resulting in loss of control and safety accidents.
2. Correct approach: Before operating the pressure relief valve, you must ensure that the Road Roller is in a shutdown state, the engine is turned off, and wait until the hydraulic system stops working completely before operating.
2. Violent operation
1. Risk: Using brute force or inappropriate tools to forcibly open or close the pressure relief valve may damage the structure of the pressure relief valve, resulting in poor sealing, valve core stuck and other problems. In addition, violent operation may also loosen the connection and cause hydraulic oil leakage.
2. Correct approach: Use appropriate tools, such as wrenches or special valve operating tools, to slowly open or close the pressure relief valve in the correct direction and force. During operation, pay attention to the resistance of the valve and avoid excessive force.
3. Failure to correctly judge the pressure
1. Risk: If the pressure relief valve is operated without knowing the internal pressure of the hydraulic system, the oil may be sprayed and hurt due to excessive pressure, or the expected pressure relief effect may not be achieved due to too low pressure. In addition, if the pressure is misjudged, the system pressure may be unstable after operation, affecting the normal operation of the equipment.
2. Correct approach: Before operating the pressure relief valve, the current pressure of the hydraulic system should be understood by observing the pressure gauge or other pressure indicating device. If there is no pressure indicating device, a preliminary judgment can be made first, such as by listening to the working sound of the hydraulic system, observing the operating status of the equipment, etc. After confirming that the pressure is within the safe range, the pressure relief valve can be operated.
4. Neglecting safety protection
1. Risk: When operating the pressure relief valve, if you do not wear appropriate personal protective equipment, such as a helmet, goggles, gloves, etc., you may be sprayed with high-pressure oil and cause injury. In addition, ignoring safety protection may also cause the operator to be injured due to other unexpected situations during the operation.
2. Correct approach: Before operating the pressure relief valve, you must wear personal protective equipment to ensure your own safety. At the same time, ensure that the operating environment is safe and avoid operating in places with open flames, flammable materials or other dangerous items.
5. Failure to clean the surrounding environment
1. Risk: If the surrounding debris and dust are not cleaned before operating the pressure relief valve, debris may enter the hydraulic system, causing system blockage, damage or failure. In addition, the surrounding debris may also affect the operator's operation and increase the risk of operating errors.
2. Correct approach: Before operating the pressure relief valve, clean the surrounding environment and ensure that the operating area is clean and tidy. Compressed air or a clean rag can be used to clean the dust and debris around the pressure relief valve to prevent debris from entering the hydraulic system.
6. Failure to check after operation
1. Risk: After operating the pressure relief valve, if no inspection is performed, the pressure relief valve may not be completely closed or the seal may not be tight, resulting in leakage in the hydraulic system or unstable pressure. In addition, failure to check after operation may also cause other potential problems to be not discovered in time, affecting the normal operation of the equipment.
2. Correct approach: After operating the pressure relief valve, carefully check the status of the pressure relief valve to ensure that it is completely closed and well sealed. The operating effect of the pressure relief valve can be checked by observing the pressure indicating device of the hydraulic system, listening to the working sound of the hydraulic system, etc. If any problem is found, it should be dealt with in time.
