Use and maintenance of pleated filter elements

Use and maintenance of the folded filter element: 1.
Open the plastic bag at one end of the folded filter element socket, check the O-ring (or gasket), and place the sealing port of the filter element in the sealing groove correctly after cleaning
.

2.
Wet the O-ring (or gasket) with process liquid (such as water)
.

3.
Protected by a plastic bag, grab the end of the filter element near the socket, and firmly press the filter element into the positioning hole of the housing
.

4.
Remove the outer packaging plastic bag, cover the head, and tighten the lifting ring to hold the bolt
.

5.
Open the air release valve at the top of the housing
.

6.
Slightly open the inlet valve to allow the liquid to enter the shell
.

　　7.
Fill the shell with liquid until the liquid overflows from the vent valve and close the vent valve
.

　　8.
Slowly open the downstream outlet valve until it is fully opened
.

　　9.
Slowly and fully open the inlet valve
.

　　10.
Flush each 10" filter element with a flow rate of 250L/ for 5~10 minutes
.

　　11.
The pleated filter element should not be subjected to the impact of excessive flow, nor should it be pressurized in the opposite direction
.

　　12.
If the filter pressure difference is greater than 0.
15Mpa , or the flow rate drops significantly, it indicates that the filter element is blocked, loosen the lifting ring pressing bolt, open the upper head of the filter, and take out the filter element.
Use and installation of 0.
2Mpah pleated filter element: (1) Filter disinfection method .
Sterilize with a sterilizer
.

Take the filter element out of the plastic bag, put it in a sterilizer, and sterilize it at 121°C for 30 minutes
.

　　2.
No need to disassemble and sterilize, the filter element is installed in the filter according to the correct method (the space between the fixing plate and the filter element is 0.
5mm)
.

　　(2) Identification of the inflow and outflow direction of the pleated filter element The pleated filter element is generally an external pressure type, and the water enters and exits from the outside of the filter element, and can be flushed back and forth in different directions
.

　　Installation operation: 1.
Wet the o-ring with lubricating oil or water, and slowly insert the filter element into the filter so that the filter element is aligned with the groove
.

　　2.
After the folded filter element is completely inserted, use the stainless steel orifice plate to press the fins on the top of the filter element, and the screws do not need to be too tight to prevent deformation due to stress
.

　　3.
Since the pleated filter element itself has been sterilized at high temperature, the filter element cannot be touched by hand
.

　　4.
Rinse the filter element as much as possible for half an hour before use
.

　　5.
When opening or closing, you need to gently turn the valve, do not open or close at once, so as not to damage the filter element when the pressure is high
.
