The hydraulic cylinder of a sanitation garbage truck has to withstand great pressure. The heavier the load, the greater the pressure it bears. Therefore, proper maintenance of the hydraulic cylinder is the most crucial aspect of maintaining the entire hydraulic system. So, what are the maintenance tips for the hydraulic cylinder of a sanitation garbage truck during its use?
In the daily maintenance of the garbage truck hydraulic cylinders, rust prevention is a top priority. Since the piston of the hydraulic cylinder frequently extends and is exposed to the external environment during operation, it is highly susceptible to oxidation, corrosive gases, and moisture in the air, leading to metal surface rust, which subsequently affects the strength and sealing of the piston. Therefore, regularly applying an appropriate amount of anti-rust grease to the piston and exposed parts of the hydraulic cylinder to form a protective layer is an effective means to prevent rust and extend its service life.
Regular replacement and internal cleaning of the hydraulic cylinder are also essential. Over time, impurities such as metal shavings and dust may enter the hydraulic cylinder, accelerating wear between the cylinder and the piston, reducing work efficiency, and even causing malfunctions. Therefore, it's necessary to periodically check and clean the internal parts of the hydraulic cylinder. Additionally, timely replacement of hydraulic oil according to its usage is important to ensure the cleanliness and lubrication of the hydraulic system. The replacement interval for hydraulic oil should be adjusted based on the manufacturer's recommendations or actual usage conditions to avoid damage to the hydraulic cylinder caused by prolonged use of aged oil.
Ensure the cleanliness of hydraulic oil, as impurities in the oil can damage the system components;
Maintain the hydraulic oil level. If the oil level is low, air can enter, causing the hydraulic cylinder system to malfunction;
Check for oil leaks. Leakage indicates a sealing issue and requires prompt replacement. In such cases, not only is oil wasted, but the power also decreases, and severe cases can lead to system shutdown;
Be familiar with the operating sounds of the hydraulic system. The sound of normal operation differs from abnormal sounds. Hearing abnormal noises indicates a fault, which should be scanned promptly to prevent minor issues from turning into major damages;
Regularly check for loose fasteners to ensure they stay tight and prevent any loosening.
The above is the maintenance knowledge for the truck hydraulic cylinder of a sanitation garbage truck. It is crucial to pay attention to this because only by using and maintaining the hydraulic cylinder properly can it perform optimally, which is key to the garbage truck's operation.
