Common faults and troubleshooting methods for garbage compression vehicles

Common faults and troubleshooting methods for garbage compression vehicles

Because the garbage truck is more than the traditional garbage truck, the hopper, the rear loading system, the two-way compression system, the PLC electronic control system, etc., the structure is much more complicated, the manufacturing needs higher technical requirements, and should be more in use. Be careful. The more complex the system, the higher the probability of problems, and the higher the requirements for the operation and maintenance of the operators. The following garbage compression vehicle manufacturers will introduce you to the common faults and troubleshooting methods of compressed garbage trucks.

1. The hydraulic system of the garbage compression vehicle has no pressure or low pressure.

Cause: The oil pump is damaged and the internal leakage is serious.

Remedy: Check for damage, repair or replace

 

Reason: The multi-way valve of the garbage compression car is damaged (including serious leakage of the valve core and abnormal pressure regulation of the relief valve)

Remedy: Check for damage, repair or replace

 

Cause: There is a lot of air in the oil circuit

Remedy: Exhaust

 

Cause: The oil filter is blocked

Remedy: Clean or replace the filter

 

Reason: Hydraulic oil deterioration

Remedy: Choose to change hydraulic oil

 

2. Garbage compression car power take-off can not be on file

Cause: Vehicle airway pressure is low

Remedy: add atmospheric pressure

 

Reason: The power take-off controls the air leakage

Remedy: Overhaul the power take-off to control the gas path

 

Cause: The power take-off gear is damaged

Remedy: Replace the gear

 

Cause: The fork or fork shaft is damaged

Remedy: Replace damaged parts

 

Cause: Spline sleeve damage

Remedy: Replace the spline sleeve

3. Garbage compression car oil pump does not produce oil or insufficient flow  

The reason: the pump does not rotate

Remedy: The spline of the pump is damaged or the power take-off is not on the file.

 

Cause: The suction pipe or the suction filter is clogged

Remedy: analysis, overhaul, clearing blockage

 

Reason: too little hydraulic oil

Remedy: add hydraulic oil to the specified height

 

Cause: The internal components of the pump are worn or damaged

Remedy: replacement or repair

 

Cause: Seal damage

Remedy: Replace

4. Garbage compression truck gear pump is noisy and has large pressure fluctuations  

Cause: The suction pipe or the suction filter is clogged

Remedy: analysis, overhaul, clearing blockage

 

Cause: There is a lot of air in the oil circuit

Remedy: Exhaust

 

Cause: The internal components of the pump are worn or damaged

Remedy: replacement or repair

 

Cause: Oil is contaminated or emulsified

Remedy: Replace hydraulic oil

5. Garbage compression car gear pump heating abnormality

Cause: There is a lot of air in the oil circuit

Remedy: Exhaust

 

Reason: too little hydraulic oil

Remedy: add hydraulic oil to the specified height

 

Cause: System blockage

Remedy: analysis, overhaul, clearing blockage

6. Garbage compression vehicle multi-way valve block does not reset  

Cause: The return spring is damaged

Remedy: Replace the spring

 

Cause: The spool is stuck by foreign matter

Remedy: remove foreign objects

 

7. Garbage compression car multi-way valve leaks serious  

Cause: The 0-ring on the valve body is damaged.

Remedy: Replace

 

8. Garbage compression vehicle multi-way valve can not adjust or stabilize system pressure

Cause: Safety valve adjusts spring failure

Remedy: Replace and re-press

 

9. Garbage compression car has no action  

Reason: related organization failure

Remedy: Detect relevant valve blocks, electrical buttons

 

Reason: Airway problem

Remedy: Check the gas path related parts

 

Cause: Oil circuit failure

Remedy: Check the status of the PLC input and output circuit to detect whether there is a wire break or original failure.

10. Garbage compression car push shovel retracts too fast or too slow

Cause: improper push-push valve pressure adjustment

Remedy: Re-pressure

11. Garbage compression car work cycle too fast or too slow  

Cause: Improper engine speed adjustment

Remedy: Re-speed

 

12. Garbage compression car is completely inactive

Cause: The main control panel switch is faulty.

Remedy: Check if the operation is correct and detect the relevant line

 

Cause: The hydraulic oil tank inlet and outlet valves are closed

Remedy: Open

 

Cause: The power take-off has an output

Remedy: Detect valve block and gear pump

 

Cause: Power take-off has no output

Remedy: Detect power take-off and pneumatic system
