What are the factors that affect the sealing of the plate and frame filter press?

The actual use of the plate and frame filter press will occasionally cause some failures, and the more common one is that it cannot be sealed. Next, Su Dong will discuss with you the reasons why the lower plate and frame filter press cannot be sealed?


First, there is insufficient pressure. The filter plate and filter cloth of the plate and frame filter press must be under strong pressure to achieve a closed filter chamber structure. When the pressure is insufficient, the pressure applied to the filter plate is less than the pressure of the filter fluid, the natural filter fluid Of course, it can seep through the gap.


Secondly, the deformation or damage of the filter plate of the plate and frame filter press. When the edge of the filter plate is damaged, even if it is slightly raised, even if one side is often worn out, it is also in contact with other filter plates. No matter what the pressure, the formed filter chamber will penetrate. We judge this according to the leakage point. The infiltration caused by the damage of the filter plate of the plate and frame filter press will generally be relatively large, and it may even be sprayed.


Finally, the filter cloth was placed incorrectly. There are many reasons why the filter chamber of a plate-and-frame filter press cannot be sealed. We need to start with the simplest one, around the filter chamber to see if the filter cloth is wrinkled or the edge of the filter cloth is broken. Since the structure of the filter chamber is made by cutting the filter plate and the filter cloth into each other, they are subjected to strong pressure. Generally, the filter plate is not prone to problems, and the rest is the filter cloth. To form a seal between the hard filter plates, the filter cloth plays a key role. The wrinkles or incompleteness of the natural filter cloth will easily cause gaps between the filter plates, and the natural filter chamber will not form a seal.


The above are the common reasons why the plate and frame filter press cannot be sealed. When it is found that the plate and frame filter press cannot be sealed, the staff can check and deal with it one by one according to the above. However, in order to prevent malfunctions, the staff should pay attention to regular inspections and repairs, especially some details must not be ignored.
