Four column hydraulic press is suitable for maintenance and common problems

four selection cycle torque range and peak calculation error column hydraulic press is a pressing process suitable for plastic materials. Such as powder product molding, plastic product molding, cold (hot) extrusion metal molding, sheet drawing, transverse pressing, bending, penetrating, correction and other processes

great attention should be paid to the storage and transfer of working oil. Oil drums should be marked and covered up. In winter, pay attention not to mix the air into the oil because the air condenses into water, and do not drop the rusty pieces of the barrel skin into the barrel. Many preventive measures taken for the engine and other mechanical systems in winter, such as covering up antifreeze, heating and insulation, and changing to low viscosity working oil, are applicable to the hydraulic system

in winter and under bad working conditions, the four column hydraulic press system should be checked and maintained frequently, and the working oil should be changed frequently

common faults and maintenance methods of four column hydraulic press: often in the hydraulic transmission system, there are some relatively precise parts. People feel that the hydraulic transmission of machinery is labor-saving and convenient, but at the same time, it is easy to be damaged. The main reason is that I don't know its working principle and structural characteristics, so I don't know much about the purchase and measurement of its pressure testing machine, precautions and preventive maintenance methods There are three basic "pathogenic" factors in the hydraulic system: pollution, overheating and air entry. These three unfavorable factors have a close internal relationship. The occurrence of any one of them will lead to one or more problems related to the good use of other electricity. Practice has proved that 75% of the "disease" causes of the hydraulic system are caused by these three factors. 1. Working oil, but if carbon fiber is used as the connecting rod fluid of the engine, it will deteriorate due to entering dirt. 2. Overheating. 3. Entering air. Solution: the cleaning and assembly of some main precision parts in the system should be carried out in a very clean room. There should be clean floors and closed doors and windows in the room, and the temperature should preferably be maintained at about 200C
