We may encounter faults in the use of filter presses, resulting in the work can not go on smoothly, summed up some common problems we encountered in the use of plate and frame filter presses and repair solutions.
Failure cause analysis:
(1) filter cloth left and right puller is not synchronised, slow action (filter press operating environment is poor, in practice, the puller is easy to be corroded, resulting in slow action, not synchronised; must be regularly cleaned and lubricated puller).
(2) The pressure of the relief valve is too high (requires regular inspection during operation every day).
(3) The opening degree of the lever is not up to the standard requirement (60~65cm).
(4) The tension of the chains on both sides of the puller is different (corrected).
(5) Drive shaft design, structure, use of strength to meet the existing process requirements.
(6) Drive shaft bearing lubrication is not in place (regular lubrication).
(7) The operation is not standardised, the skills do not pass (strengthen management).
Repair:
The solution of plate damage:
1, it is recommended to use nylon cleaning scraper, regularly remove the sludge from the inlet;.
2、Check the filter plate and clean the drainage port. Open the corresponding valve to release the pressure;.
3、Clean the filter plate carefully and repair the filter plate;.
Second, repair steps:
1、Clean up the trench, keep the trench clean.
2、Black and white two kinds of repair agent according to the ratio of 1:1 to mix well.
3、Mix the good repair agent coated in the groove, coated until full; 4、Quickly set the filter cloth, repair the filter plate.
4, fast set of filter cloth, filter plate squeezed together, so that the patch and the filter cloth stick together, squeeze the groove.
5、Squeeze for a period of time, the adhesive naturally forming, the plate frame can be used normally.
