Fault Diagnosis and Treatment Method of Sealed Garbage Truck Hydraulic System
The hydraulic system is an important part of the sealed garbage truck. Whether the hydraulic system is working properly determines whether the garbage truck can operate normally, so the daily maintenance and maintenance of the chess hydraulic system is very important. If the hydraulic system of the sealed garbage truck fails, how can we solve it? The following Xiaobian share some treatment methods on this issue.
1. When the sealed garbage truck hydraulic system is not working properly, check the power take-off first to see if it is properly meshed. In addition, check whether the hydraulic oil in the tank is sufficient and whether the suction pipe ball valve is fully open.
2. The hydraulic system of the sealed garbage truck has the action but no power. Check whether the gear oil pump fails and whether the system pressure reaches the specified value.
3. The action of the hydraulic mechanism of the sealed garbage truck becomes slow, check whether the gear oil pump fails, whether the oil sucking oil filter and the oil returning oil filter core are plugged.
4. The hydraulic mechanism of the sealed garbage truck has no action. Follow the steps below to check it.
aã€Whether the amount of oil in the hydraulic tank is sufficient. When insufficient, hydraulic oil should be added;
b. Observe whether the oil inlet pipe from the fuel tank to the oil pump will cause the oil sucking phenomenon due to aging. If this is the case, replace the inlet tube.
c. Check if the gear pump fails. Put a pressure gauge, turn the pressure regulating bolt, and observe whether the table has reached the specified value;
d. If the pressure regulator bolt fails to reach the specified hydraulic pressure after it is fully screwed in, the gear oil pump will fail and the gear oil pump must be replaced;
e. If the gear oil pump is working properly, it is the clogging of the multi-way valve spool. The valve plug should be removed to remove impurities and used after reinstalling.
5, after the above conditions are still excluded after the exclusion of the reasons, or damage to the hydraulic parts, it should be informed of professional personnel maintenance, unauthorized disassembly.
The above is the solution to the failure of the sealed garbage truck hydraulic system. Usually in the course of use, the owner's friends should also do maintenance work on the hydraulic system in time, which can also reduce the occurrence of failures. Finally, users should be reminded that the pressure regulating device of the hydraulic system is a pressure regulating bolt on the multi-way valve. After the bolt is calibrated and locked tightly, it cannot be arbitrarily moved. It is also not allowed to adjust the oil pressure.
