Cause of damage to diaphragm filter filter

   In the long-term use of the diaphragm filter, in addition to the easily damaged filter cake, the diaphragm filter plate was also replaced.Filfilter that looks like a hard diaphragm filter will also be used for a certain amount of time.The worn, worn common diaphragm filter filter will be replaced within one year.Then someone wondered how the filter was damaged during the filter process?How to wear it?
   In the process of years of work, the loss of the filter filter plate will have many aspects, I think there are mainly the following aspects.
  Since the filter cavity of the diaphragm filter is squeezed and spliced by a filter plate and requires a high pressure working environment during filtration, the natural interior is solid or liquid, and it is very efficient at high pressure.Pressure action.Internal energy, if the gap between the filter plate and the filter plate is slightly weak or has a little gap, it will lead to a liquid ejection with a strong internal force.Due to its high energy, it is sufficient for its diaphragm filter.Filfilter plates were washed one to one.As time passes, shots get larger.There will be many gaps between the filters and the filter plates.The larger the gap, the more liquid injection.The more places placed, the vicious circle will speed up the damage of the press filter unit, and the final diaphragm filter unit will no longer meet the basic conditions of the press seal.The filter plate of the diaphragm filter must be replaced.
  During the use of diaphragm filters, they will accumulate locally if they are not well dispersed evenly into the space of the filter chamber.The filter chamber must be kept higher due to the operation of the diaphragm press.Pressure, under the action of strong pressure, due to the local accumulation of solid, is due to the pressure of the diaphragm filter filter can not pass through the pressure plate resulting in uneven pressure filter is too high, long-term action pressure filter will deformation or break.The common performance is that the filter plate of the filter breaks simultaneously with the original filter, which will also damage the diaphragm filter.
  Both phenomena can explain the damage of most diaphragm filters and can not be well avoided during press use.That is why the filter needs to be replaced after a considerable time.
