Today, we will introduce the reasons why the hydraulic scraper of the compression garbage truck does not work. I hope it will be helpful to everyone. The most common reasons for the hydraulic scraper not to work are two reasons. First, the valve body controlling the operation of the hydraulic scraper cylinder in the multi-way valve group of the vehicle is malfunctioning, resulting in that the operation instruction cannot be transmitted. Second, the hydraulic cylinder itself has a problem, and the common is that the seal is damaged, which causes the cylinder to not work.
In response to the above two points, we can adopt the following countermeasures. The multi-way valve group is composed of multiple multi-way valve bodies, each of which is an independent unit. As long as it is a brand of excellent quality, the valve body itself will fail. It is uncommon to appear after short-term use. In most cases, the valve body is blocked by dirt in the oil body because the hydraulic oil is not replaced in a timely manner. This is how we can remove the valve body, clean it with a special cleaning agent, and install it after air drying. If the problem is solved, then it is ok, if the problem is still the problem, you need to replace the valve body.
For the problem of the oil cylinder itself, we can observe whether there is oil leakage at the sealing ring of the oil cylinder, or whether the hydraulic oil pipe bursts, and after the problem is found, the targeted maintenance failure is solved.
