After a long period of use, garbage trucks are inevitably prone to problems. Although their hydraulic system design is very precise, some issues are also inevitable. If we do a good job in the daily maintenance of garbage trucks, we can avoid the hidden dangers that may cause problems. The maintenance of the hydraulic cylinder of the garbage truck is also one of the maintenance items. So let me teach you how to maintain hydraulic cylinders and what are the common fault manifestations.

1. Overflow valve core stuck: Check if the overflow valve core is stuck by impurities. At this time, it is necessary to clean or replace the overflow valve core with a new one.

2. Insufficient hydraulic oil: The hydraulic oil in the garbage truck's fuel tank is too low, below the standard level of the tank. Timely replenish the hydraulic oil.

3. Blockage of oil suction filter element: It is necessary to clean or replace the oil suction filter element in a timely manner.

4. Excessive impurities in hydraulic oil: After prolonged use, excessive impurities in hydraulic oil can clog the multi way valve, so it is necessary to regularly replace the hydraulic oil in the garbage truck. And when replacing hydraulic oil, a dedicated filter should be used to prevent impurities from entering.

5. Hydraulic cylinder failure: The hydraulic cylinder has malfunctioned and needs to be replaced in a timely manner.

The above is how to maintain the hydraulic cylinder of a garbage truck and common troubleshooting methods. The design of hydraulic systems is precise, and occasional small problems are mostly caused by hydraulic oil pollution, so daily maintenance is essential.
