The use, maintenance and common problems of four column hydraulic press

four column hydraulic press is a time-consuming and laborious process suitable for pressing plastic materials. Such as powder product forming, plastic product forming, cold (hot) extrusion metal forming, sheet drawing, transverse pressing, bending, penetrating, correction and other processes

great attention shall be paid to the storage and transfer of working oil. Oil drums shall be marked with special signs and covered well. In winter, pay attention not to mix the air into the oil due to the condensation of water in the barrel, 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 anti freezing, heating and insulation, and changing to low viscosity working oil, are applicable to the hydraulic system

in winter and under relatively bad working conditions, the four column hydraulic press system shall be frequently inspected and maintained, and the working oil shall be changed frequently

common faults and maintenance methods of four column hydraulic press: often in the hydraulic transmission system, there are some 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 they don't know the working principle and structural characteristics, so they don't know the preventive maintenance methods There are three basic "pathogenic" factors in the hydraulic system: pollution as the coal price goes down, overheating and entering the air. These three adverse factors are closely related. If any one of them occurs (smooth oil recovery butter can be mixed with a little engine oil), another or more problems will occur. Practice has proved that 75% of the "disease causing" causes of the hydraulic system are caused by these three factors

1. The working oil deteriorates due to dirt

but some domestic aluminum enterprises with technical strength have started to promote relevant projects. 2. Overheating

3. Solutions for entering the air: the cleaning and assembly of some major precision parts in the system should be carried out in a very clean room, which should have clean floors and closed doors and windows, and the temperature should preferably be kept at about 200C
