Oil filter of common faults and solutions analysis 
  
(1) plate damage 


    Van filter plate damage is a common fault. If the large number of damaged plate, the response analysis of the following factors: 


    plate manufacturing quality; 


    plate material selection and feed pump head matches; 


    membrane squeeze mode, you should also consider the amount of oil filter and internal diaphragm plate lined processing quality. 


    Under normal conditions, the pressure plate is in equilibrium on both sides. When both sides of the plate in the different filter stages, namely the side of the filter, the other side of the hydraulic press, plates formed on both sides of the pressure difference, thereby damaging the plate. The reason: 


    unloading process, the plates on both sides of the amount of residual sludge big difference; 


    filter press Start After filtration, the feed pump midway parking time is longer, the filter cake indoor semi-fluid state with varying degrees of subsidence; 


    clogging the feed plate. 


    (2) spray material between the plates 


    Automatic vacuum oil in the filter operation, the spray material between the plates phenomenon, its causes: 


    in the clamping plate border surface appears folded cloth; 


    cloth breakage; 


    both sides of the beams with varying degrees of lateral bending (horizontal direction); 


    thrust plate is not pressed or hydraulic cylinder clamping force is too small. 


    Solving measures, unloading carefully clean the residual cake plate clamping surface (especially in the lower part), or promptly wash plates, to ensure clamping plate surface cleaning; cloth tied good will to ensure its smoothness .
