1. Air intrusion into the hydraulic system is the main reason for noise

2 The overflow valve is unstable. For example, the valve core is stuck or can not move flexibly in the valve hole due to improper cooperation between the slide valve and the valve hole, or the contact between the cone valve and the valve seat is stuck by dirt, the damping hole is blocked, the tension spring is inclined or invalid, which causes the system pressure to shake and noise.

3  Oil cylinder manufacturer Due to improper adjustment of the reversing valve in the middle, the spool of the reversing valve moves too fast, forming a reversing impact, thus causing noise and oscillation.

4 Mechanical oscillation, such as thin and long oil pipes, many elbows without fixing, is easy to cause pipe vibration when the oil flow expires, especially when the flow rate is high; The rotation of the motor and hydraulic pump is unbalanced, or the alignment is not good when the device is installed, or the coupling is loose, which can cause oscillation and noise.

The maintenance of the tailboard is not complicated. The main accessories of the tailboard are the electric cabinet, panel, oil cylinder, hydraulic pump, pipeline and electrical system. Generally, there is no major problem with the panel. If there is no other reason, the panel is firm and reliable. The panel has undergone strict surface treatment such as acid pickling, phosphating, shot blasting, paint baking, etc., with neat structure and rust proof and corrosion proof appearance. Oil leakage is a common problem in the whole tailboard. There are many reasons for oil leakage, for example, the tail plate is slightly installed, which causes the oil cylinder to be squeezed and worn; The seal ring is worn and damaged, causing oil leakage; Overload lifting cargo, causing damage to oil pump; Excessive hydraulic oil addition causes hydraulic oil leakage and other reasons.

1. Oil leakage is not terrible. It is OK to find and solve the problem in time. Of course, for the truck master, it may not be so professional to deal with such problems in time, but it can be solved by finding the problem in time and letting the manufacturer deal with it, or driving to the maintenance point for maintenance. Maintenance costs are high now. If you know some skills in this area, it's still very cost-effective.

two Hydraulic cylinder manufacturer The maintenance of the tailboard is mainly to replace more parts. Most of the wear parts are easy to damage, while the surface of the tailboard is not easy to damage. The steel plate is welded and firm. Among the tailboard quality produced by all enterprises, Kaizhuo Li tailboard, Niuli tailboard, Anzhong tailboard and Dazhou tailboard are among the top ones in China, accounting for more than 90% of the whole market. If you want to reduce the maintenance or replacement of parts for the tailboard, it is cost-effective to choose a large manufacturer and a high-quality tailboard manufacturer to ensure both after-sales service and installation quality of the tailboard.
