Each hydraulic system must be flushed before it is put into use, and the purpose of flushing is to remove contaminants, metal chips, fibrous compounds, iron cores, etc. remaining in the system. During the first two hours of work, even if the system is not completely damaged, will also cause a series of failures.
The spool of the flow valve in the hydraulic cylinder is blocked, which can easily cause the action of the hydraulic cylinder to fail: it is necessary to check whether the oil in the hydraulic cylinder has contaminants, and check whether the valve body is worn;
The key technologies of hydraulic transmission include: (1) Hydraulic transmission and control technology; (2) No leakage of hydraulic system and components; (3) Hydraulic system and pollution control technology;
