What Are The Precautions For Installing A Liquid Filter Bag?

What are the precautions for installing a liquid Filter Bag?

    The working principle of the liquid Filter Bag is pressure filtration, the quality of the liquid Filter Bag is good, pay attention to see the filter cloth efficiency, pore size distribution, density, thickness, weight, permeability, breaking strength and other technical indicators. Liquid Filter Bags need to pay attention to the installation of the matter:

  1, come up with a new Filter Bag, the new Filter Bag sealed carton, the unused Filter Bag must be re-loaded into the plastic bag to prevent dust pollution.

  2, turn off the power to stop the pump, close the inlet and outlet valves (for the user who has been using the Filter Bag).

  3, release the pressure, for safety reasons, to ensure that the nozzle is rushed to a safe place. Open the exhaust valve to slowly lower the filter pressure (for users who have already used the Filter Bag).

  4, open the lid, to ensure that the cartridge pressure drop to zero after opening the lid. Take out the used Filter Bag. (For users who have already used the Filter Bag).

  5, to ensure that the filter edges are cleaned up.

  6, check the basket of arc and edge. The upper edge of the basket and the contact surface of the filter cartridge must be flat. If there is no basket or basket installation error will lead to filter failure.

  7, the installation of new Filter Bags, Filter Bags must be inserted into the basket, the bag bag seal must be properly seated in the sealed slot.

  8, check the gasket, select the fluid compatible with the gasket. Close the cover, and note that when the filter cover is closed, make sure that the washer does not twist or leave the slot and tighten the ring nuts clockwise.

  9, close the exhaust valve, open the pump switch. Open the inlet valve and slowly open the valve to see if it leaks. When a leak occurs, immediately close the inlet valve, from the start, open the outlet valve.

 To know the service life of the filter material and the permeability of the material are inextricably linked, the material permeability is low, the Filter Bag using the original pressure difference is small, slow pressure, natural Filter Bag life is long, and vice versa in contrast. In addition, the surface treatment process control is also good or bad also affect the life of the Filter Bag. Liquid mat is the surface of the strict singeing process, if the pursuit of surface finish, there have been burning the molten fiber will plug the filter channel, will naturally reduce the liquid through, improve the pressure drop of the filter, and ultimately reduce the Filter Bag Of the service life.

    Filter Bags as a key link in the filter link, Filter Bag quality to a large extent determine the filtering effect, and now we understand when the bag filter when the replacement bag.

(1): in full accordance with experience to roughly determine the replacement time.

(2): the inlet and outlet of the filter are installed on the pressure gauge, through the pressure gauge before and after the pressure difference to determine the time to replace the Filter Bag, the general Filter Bag can withstand the pressure difference of 0.5 ~ 1kg / Cm2, when the pressure reaches this range, it should be promptly replaced Filter Bags to avoid cracking bag bags, affecting the filter filter effect, not because of small loss.

Filter Bag installed on the impact of good or bad effect of dust, the following to explain how to properly install the Filter Bag:

First, the bag should be shipped to the installation location of the bag, and install a remove a; Filter Bag can not be dragged on the flower board to prevent the bag surface and metal scrap on the board friction, damage Filter Bag.

Second, from the box out until it is installed to the flower plate hole so far, can not touch any metal objects and rough surface objects.

Third, through the flower plate hole to use the supplier to provide protective cover, to prevent the Filter Bag touch the edge of the flower board.

Fourth, the Filter Bag should be firmly fixed in the flower plate hole, neither too tight nor too loose. Such as the installation of the situation is too tight, the application of rubber pile along the bag bag gently beat, so that between the pocket and the flower plate match.
