A safety valve is a device usually installed in a hydraulic system. Its function is to release part of the hydraulic fluid when the system pressure exceeds a preset value to prevent the pressure from continuing to rise and causing system failure or danger. Safety valves for cranes play a vital role in the crane hydraulic system. Its main function is to protect the crane hydraulic system from dangers caused by pressure overload.
1. Control system pressure: The safety valve can be set to a value below the maximum working pressure that the system can withstand. When the system pressure exceeds the set value, the safety valve will automatically open to release the hydraulic fluid; once the pressure drops to the range set by the safety valve, the safety valve will close.
2. Protect hydraulic components: Various hydraulic components (such as hydraulic cylinders, hydraulic pumps, etc.) in the crane hydraulic system have their rated working pressure ranges. When the system pressure exceeds the rated pressure of these components, the safety valve protects against damage or failure.
3. Prevent pipeline bursting: If the pipelines or components in the system leak or fail during use, it may cause a sudden increase in pressure, resulting in the risk of pipeline bursting. This danger can be prevented by properly setting the safety valve.
The following measures can effectively prevent the danger caused by pressure overload:
1. Proper selection and installation of safety valves: Choosing the right safety valve is crucial. It is necessary to consider the maximum working pressure of the crane hydraulic system and the rated pressure range of the hydraulic components, and select a matching safety valve. Safety valves should be installed to meet the manufacturer's recommendations and guidelines.
2. Regularly inspect and maintain the safety valve: The safety valve needs to be inspected and maintained from time to time to ensure that it is working properly. Check valves regularly for leaks or blockages, and clean or replace damaged valves. Make necessary adjustments and replacements as needed.
3. Establish a complete hydraulic system monitoring and alarm system: In the crane hydraulic system, the monitoring and alarm system can detect abnormal conditions in the system in time and issue an alarm. This allows timely measures to be taken to prevent the risk of pressure overload from developing further.
4. Strictly abide by operating procedures and safe operating guidelines: Crane operators need to strictly abide by operating procedures and safe operating guidelines. They should understand the working principle of the crane hydraulic system and monitor the system according to actual conditions. When any abnormality occurs, operation should be stopped immediately and inspection and repair should be carried out.
