Oil filter for oil industry is very important, oil filter can guarantee the quality of oil, so if the oil filter failure to ensure the correct operation of the oil filter process, so the common fault solution of oil filter is what? The common faults of the oil filter are damaged by filter plates and two kinds of spraying material between the filter plates, and the following are analyzed separately for different faults: the filter plate of the oil filter damaged the oil filter plate of the oil filter machine is a common failure. If the number of damaged filter plates, the following factors should be analysed:
The manufacture quality of the filter plate, the selection of the quality of filter plates and the matching of the head of the feeding pump; in the diaphragm press, the paper should consider the volume of diaphragm plate filter oil and the machining quality of the internal steel lining. Under normal conditions, the pressure on both sides of the filter plate is balanced. When the two sides of the filter are in different stages of filtration, i. e. the side is filtered and the other side is pressed for liquid force, the pressure difference is formed on both sides of the filter plate, thereby damaging the filter plate. The reason: unloading process, the residue of the filter plate on both sides of the mud; Filter press began to filter, the feeding pump in the middle of a long time, the filter chamber half-flow of the filter in different degrees of sinking; Filter plate between the oil filter press Vacuum oil filter in the filtration operation, the filter plate between the phenomenon of spraying, the reason: ① in the pressure of the filter plate border, the filter cloth appears folding, ② filter cloth occurrence breakage; ③ the cross-beam on both sides of the oil filter has different degrees of lateral bend (horizontal direction); The solution is to remove the residual filter cake (especially the lower part) on the pressing surface of the filter plate when the material is carefully cleaned, or rinse the filter plate in time to ensure the cleaning of the pressing surface of the filter plate; bundle cloth to ensure its smoothness. In order to ensure the normal operation of the oil filter, the malfunction of the oil filter must be noticed and solved.
