Bag filter filtration operation and precautions


The bag filter is easy to operate. When using it, you only need to install the filter bag of the required fineness level in the filter cartridge, check whether the O-ring is intact, and then tighten the ring bolt of the filter cartridge cover to start working. After the pump is started, the pressure gauge on the filter rises slightly, and the initial pressure is about 0.05MPa. With the prolongation of use time, the filter residue in the cylinder gradually increases. When the pressure reaches 0.4MPa, stop the machine and open the cylinder cover to check the residue left in the filter bag. If the situation is different, the filter bag can be replaced to continue to use (the filter bag can generally be reused after cleaning). The pressure of the filter is generally adjusted at 0.1-0.3MPa, which can be adjusted through the return pipeline or the return valve on the pump. If the filter pressure is too high, it will damage the filter bag and the protection net, so special attention should be paid.

Bag filter is mainly used for paint, beer, vegetable oil, medicine, chemicals, petroleum products, textile chemicals, photosensitive chemicals, electroplating solution, milk, mineral water, hot solvent, latex, industrial water, sugar water, resin, ink, Industrial wastewater, fruit juice, edible oil, wax, etc. The bag filter needs to replace the filter bag: 1. The high-efficiency filter bag is made of fine fibers, and these materials are weak in hydrophilicity. The surface of the fiber will not be wetted by water, so like other filter elements using the same material, it must be wetted with some other liquid with lower surface tension before use.

Before installing, you must soak the filter bags in a pre-wet solution that matches the filter fluid for a few minutes. 2. Make sure to open the upper cover of the bag filter. 3. Put the upper cover firmly and take out the filter bag carefully.

4. Put in a new filter bag, please refer to the installation process. Maintenance and replacement of the Ο-shaped sealing ring: 1. Maintenance: When using, the Ο-shaped sealing ring should be placed in the Ο-shaped groove to avoid improper extrusion and deformation of the Ο-shaped sealing ring; when not filtering, the Ο-shaped sealing ring must be taken out Wipe it clean, otherwise the residual liquid will adhere to its surface after solidification, resulting in hardening and poor sealing. 2. Replacement: If the Ο-shaped sealing ring is aged or damaged, please replace it in time.

When replacing, the O-ring of the same type should be selected. Note: 1. Under normal use, the filter and support net are guaranteed for one year, and damage caused by improper use is not covered by the warranty. 2. The maximum design pressure of the standard bag filter is 1.0Mpa, except for special specifications where the recommended maximum working pressure is 0.5Mpa.

3. The maximum design pressure inside the bag jacket filter jacket is 1.0Mpa, and the maximum recommended working pressure is 0.6Mpa. 4. The design pressure of the multi-bag filter is 1.0Mpa, and the maximum recommended working pressure is 0.6Mpa. Poolking is the best swimming pool equipment manufacturer and supplier in China.
