The various actions of the compressed garbage truck are mainly accomplished through the action of the multi-way valve. Once there is a problem with the multicircuit valve, the automobile cannot run or stop normally. It is impractical for ordinary consumers to repair the multi-way valve by themselves because its interior is full of precision parts and cannot be repaired without specialized tools and skills. However, if a multi-way valve fails for a long period of time, it is mainly due to internal clogging. As hydraulic fluid flows into the circuit, scrap iron from vehicle wear will flow with the hydraulic fluid. If the scrap iron flows into the multi-way valve, it will cause the valve to become clogged, preventing it from working properly. We can clean it with diesel fuel and blow it dry with air gun.
If the failure remains so long, it needs to be replaced. At present, there are quite a number of manufacturers producing multi-way valves in China, and the level of product quality varies. When replacing the product, we first need to observe the connector of the original multi-way valve. Different manufacturers have different connectors. We first need to make sure that the new product can be installed properly. For those who are in a position to do so, we suggest that it is best to choose an imported or joint venture brand. Although the price is higher, the failure rate and durability are really better than domestic products.
Compressed garbage truck oil pump rattling how to do
Compressed garbage truck oil pump will inevitably have noise in the process of using, because when the hydraulic oil is running at high speed in the system, it will inevitably produce some noise, but the noise is within the acceptable range. If the noise is exceptionally loud, the problem needs to be solved and eliminated. Let us describe the possible causes of abnormal noise.
First, worn or scored oil pump bearings or shafts. If parts are severely worn or scored, replace the parts or replace the oil pump and find out the cause of the scoring. The internal organs of the oil pump or accumulated sludge are clogged. Remove the oil pump and piping, clean the hydraulic system and find out the cause of contamination.
Second, the oil pump parts are damaged or damaged. The crude oil filter is clogged. If the oil pump speed is too high, run the oil pump at the recommended speed and adjust the gas pedal. The oil suction pipe is clogged or squeezed and oil flow is not smooth. Clean or replace the oil suction pipe.
Third, the level in the oil tank is too low. Fill the tank to the required level and check the system for leaks. Oil tank breather is clogged. Remove breather cap, flush and clean breather. There is gas in the hydraulic fluid. Tighten or replace the breather pipe, check the system for leaks, and replace the seals on the pump shaft.
Fourth, the viscosity of the oil is too high, replace with low viscosity oil. Parts are stuck with each other, repair the parts stuck with each other, clean the parts and replace them if necessary.
