Precautions when using the filter cartridge filter

Stainless steel filter cartridges must be inspected for completeness and damage before use, and then installed as required. The new filter must be cleaned with detergent (please do not use acid cleaning). After cleaning, use high-temperature steam to sterilize, disinfect and wash the filter to avoid contamination. When the filter is installed, the inlet and outlet should not be reversed. The port on the side of the pipe filter is the liquid inlet, and the pipe connected to the filter socket is the clean liquid outlet. The new filter element is a non-perforated plastic package that is packaged in a plastic bag by a manufacturer in a clean production plant. The filter element with higher requirements is used, and it must be sterilized by high-temperature steam after installation.

When the filter element is inserted into the port, the filter element must be vertical. After inserting the port, the platen is fastened to the tip fin, and the tightening screw does not move. After the inlet of the filter element of the 226 interface, it should be rotated by 90 degrees. This is the key to the installation. If there is a little carelessness, it will not reach the seal and it will leak easily, which will not meet the requirements.

The pressure gauge of the cylinder is a liquid pressure display. If it is a secondary filtration, it is normal for the filter to have a slightly smaller index. The longer the usage time, the higher the pressure and the lower the flow rate, which means that most of the filter gap has been Block, flush or replace with a new filter. When filtering, the pressure used is generally about 0.1 MPa, which can meet the production needs. As time and flow rate increase, the filter core pores are clogged and the pressure increases, generally not exceeding 0.4 MPa, and the Zui height must never exceed 0.6 MPa. Doing so can damage the filter element or be broken down, especially when using precision filters.

For backwashing the filter element, be sure to use sterile water, otherwise it will contaminate the filter element. The recoil method, the original export is imported, the sterile water is driven in the opposite direction (note that the raw liquid filtration pipe is closed), and the sewage outlet is opened, and the operator sees that the filtrate is obviously improved.

When the production is not finished, try to discharge the filtrate as much as possible. The downtime is not long. Generally, do not open the machine. Do not remove the filter. The downtime is long or the filtrate should not be stored overnight. The filter must be cleaned and the filter must be cleaned (can also use the recoil method) . Optional use, pay attention to the required flow, pressure, pump head should be matched, the selection of vortex pump, infusion pump is generally appropriate, centrifugal pump is not applicable. The maintenance method of the filter equipment is not used for a long time. The filter must be cleaned, the filter element is unplugged, washed and dried, and stored in a plastic bag to prevent contamination. The filter should be cleaned and stored without damage. The replaced filter element should be immersed in the acid-base wash solution, the soaking time should not exceed 24 hours, and the acid-base temperature should generally be 25 °C - 50 °C. It is recommended that the acid or alkali to water ratio is 10-20%. The filtrate with high protein content and the filter element are soaked with the enzyme solution. The cleaning effect is good, and the product is updated and reused. It must be cleaned and then steam disinfected. The cleaning and disinfection is very important for the water filter and the drying filter. Filter core disinfection should pay attention to the time and temperature, polypropylene in the high temperature disinfection cabinet at 121 ° C is appropriate, with steam sterilization at 0.1MPa steam pressure, 130 ° C / 20 minutes is appropriate, polysulfone and polytetrafluoroethylene Steam sterilization, can reach 142 ° C, pressure 0.2MPa, time is about 30 minutes is appropriate, if the temperature is too high, the time is too long, the pressure is too large, will damage the filter.Uv Curing Screen Protector, UV Cured Screen Protector, UV Light Screen Protector, Uv Curing Film Sheets, UV Screen Protector
