What are the faults and maintenance methods in the metal press?

　　Metal press everyone is not strange, then do you know about the hydraulic transmission system of the press? There are some parts in the hydraulic transmission system, and the operator feels that the hydraulic transmission of the machine is convenient and labor-saving, but its disadvantage is that it is quite easy to damage. The reason is that its structural characteristics and working principle are not clear, so we do not know how to carry out preventive maintenance on it. Hydraulic system problems have three factors:

　　Into the air, pollution, overheating. These three factors are very bad, there is a close internal connection between them, the solidarity is relatively strong, any one of the problems, will be associated with another and multiple problems. After long-term practice, 75 percent of the causes of disease in hydraulic systems have a lot to do with these three aspects.

　　1. Overheating;

　　Second, the working oil deteriorates due to entering the dirt;

　　Third, into the air solution: some of the main assembly and cleaning in the system must be carried out in the most clean room, closed doors and Windows and clean floors, the best room temperature, these are indispensable factors in the room.
