The hydraulic system of a bundle extractor plays a crucial role in the equipment. Its functions and maintenance methods are as follows:
1. Functions of the Hydraulic System
– Provide Power: The hydraulic system delivers hydraulic oil to various actuators such as hydraulic cylinders and hydraulic motors through a hydraulic pump, providing essential power for the operation of the equipment. For example, the pushing device on the main trolley may use a hydraulic cylinder as the power source for tube bundle pushing operations.
– Control Movement: The hydraulic system can precisely control the movement of the equipment. By adjusting control components such as flow valves and directional valves, it is possible to accurately control the speed and direction of the main trolley, auxiliary trolley, and various clamps, ensuring the accuracy and stability of tube bundle extraction and reinsertion operations.
– Overload Protection: When the equipment is subjected to loads beyond its design capacity, the hydraulic system can automatically stop operating, effectively preventing equipment damage and potential safety accidents. For instance, if the hydraulic device on the main trolley detects an overload, it will automatically cut off power or take other protective measures.
– Auxiliary Adjustment: In some cases, the hydraulic system can also assist with equipment adjustments. For example, the wedge adjustment block under the small trolley’s pallet may be driven by a hydraulic cylinder to adjust the height of the small trolley’s pallet, accommodating tube bundles of different heights.
2. Maintenance of the Hydraulic System
– Regular Inspection and Replacement of Hydraulic Oil: Hydraulic oil is a critical component of the hydraulic system and needs to be regularly checked for quality and cleanliness, and replaced timely based on usage conditions. Dirty or degraded hydraulic oil can affect the normal operation of the system and even cause faults.
– Check Hydraulic Lines and Connectors: Regularly inspect hydraulic lines and connectors for leaks, wear, or looseness. If any issues are found, they should be addressed promptly to prevent hydraulic oil leakage or pressure loss.
– Maintain Hydraulic Components: Regular maintenance and servicing of hydraulic pumps, cylinders, motors, and other hydraulic components are necessary. This includes cleaning, lubrication, and tightening connections to ensure stable and reliable performance.
– Remove Air: If air enters the hydraulic system, it can affect the system’s working pressure and stability. Therefore, during maintenance, it is important to remove air from the system to ensure the purity and fullness of hydraulic oil throughout the system.
– Train Operators: Professional training for operators is essential to familiarize them with the operation and maintenance of the hydraulic system. Operators should strictly follow operational procedures to avoid faults caused by improper operation.
In summary, the hydraulic system is a key part of the bundle extractor’s normal operation. It provides strong power support for the equipment and ensures the safety, efficiency, and reliability of tube bundle extraction and reinsertion operations through precise control and protection mechanisms.
