The reason why the filter cavity of the security filter cannot be sealed

In order to maintain the accuracy of the water output and protect the subsurface water equipment, a security filter is required. The reasons why the filter cavity cannot be sealed are as follows:

1. The filter is deformed or damaged

When the edge of the filter plate is damaged, even if it protrudes slightly, even if one side is often worn, it will come into contact with other filter plates, and the formed filter chamber will be exposed regardless of the pressure. Depending on the leak point, the damage to the filter plate is usually significant.

2. Improper placement of filter cloth

There are many reasons why a filter chamber cannot be sealed. We need to start with an easy way to wrap around the filter chamber to see if the filter cloth is wrinkled or if the edge of the filter cloth is damaged. Since the structure of the filter chamber is formed by cutting the filter plate and the filter cloth and relying on strong pressure, the ordinary filter plate is not a simple problem, and the rest is the filter cloth. To form a seal between the filter plate and the critical filter cloth. Wrinkles or damage to the filter cloth can create gaps between the filter plates without the filter chambers forming a seal.

3. Insufficient pressure of bag filter

The filter plate and filter cloth have to withstand a lot of pressure to complete the closed filter chamber structure. In the absence of pressure, the pressure applied to the filter plate is less than the pressure of the filtrate, and the filtrate will not move to generate reasonable energy from the gap.

If the security filter is to be cleaned, the system needs to be shut down and the filter element can be removed for cleaning. This will not maintain the continuity of the water supply system, which will affect production efficiency and greatly increase production costs. If the filtration precision of the raw water is high (the filtration precision is above 100 microns), it is recommended that you set up an automatic sewage as a pre-security filter, which can also be backwashed and cleaned without stopping the machine. The raw water passes through two Stages are filtered, and the accuracy of wastewater quality can also be guaranteed.
