Introduction editor

U9彩票799ccMicroporous filter is a new type of filtration equipment developed at home and abroad. It can filter liquid and gas particles above 0.1um and these bacteria. It has the advantages of high filtration accuracy, fast transition speed, low adsorption, no media shedding, acid and alkali corrosion resistance, and convenient operation. Now it is widely used in the necessary equipment of medicine, chemical industry, electronics, beverage, fruit wine, biochemical water treatment, environmental protection and so on.

U9彩票799ccHow to useedit

1. Thoroughly clean the filter and the connecting parts of the filter, and install the filter element and housing correctly.

2. Before starting the machine, first check whether the pressure pump rotates in the forward direction, whether the connection is tight, and whether the valves are closed.

3. Slowly open the inlet valve before starting the machine, exhaust the air, and then open the outlet valve for normal filtration.

4. If the filter pressure difference is greater than 0.1Mpa or the flow rate drops significantly, it indicates that most of the pores of the filter element have been blocked, and it is recommended that the customer clean or replace the filter element.

Structure function editing

The stainless steel microporous filter is composed of a folded microporous membrane filter element and a stainless steel outer cylinder. It is equipped with a single or multi-core filter element. The filter cylinder is connected by a quick-release clamp or a quick-opening ring bolt. The loading and unloading of the filter element and the cleaning of the filter are very important Convenience. The inner surface of the filter is mirror-polished (roughness Ra≤0.28μm), there is no sanitary corner, and it meets the requirements of "FDA" and "GMP"

U9彩票799ccMicroporous filters are divided into chemical grade and food grade. Food grade must be manufactured in accordance with FDA standards. The filter material is high-quality stainless steel (304/316L), both inside and outside are finely polished, and there is no dead corner. It is characterized by small size, light weight, convenient use, large filtering area, low clogging rate, fast filtering speed, no pollution, good thermal dilute stability and good chemical stability.

U9彩票799ccThis series of stainless steel microporous filters can filter out most of the particles, so they are widely used in fine filtration and sterilization processes.

Microporous filter

Membrane (PTFE) filter element, cellulose acetate membrane (CN-CA) filter element, the filtration accuracy is from 0.1-60um, the length is 10; 20; 30 and 40 inches (ie 250; 500; 750; 1000mm). The above-mentioned filter element is resistant to The pressure is 0.42mpa and can be recoiled. There are two types of interface modes: plug-in (222 and 226 seats) and flat mouth.

U9彩票799ccWhen the microporous filter leaves the factory, the user must configure the filter element of different forms and materials according to the filtering purpose, media condition, and configuration before use. For example, GMP factory pharmaceutical water can be used in series with two sets of 5um and 1.oum folded membrane simple filter elements. In the fermentation industry, air filtration, as shown in the figure, can sterilize the incoming air, remove bacteriophage, and seal the exhaust gas for processing, reaching the HIM standard for bacteria filtration in the United States.

Maintenanceedit

U9彩票799ccMicroporous filters are now widely used in the necessary equipment of medicine, chemical industry, electronics, beverage, fruit wine, biochemical water treatment, environmental protection and other industries. Therefore, its maintenance is very necessary, not only to improve the filtration accuracy, but also to extend the service life of the microporous filter. What should we do to maintain the microporous filter?

There are two types of microporous filters in the maintenance of microporous filters, namely precision microporous filters and coarse-filtered microporous filters.

1. Precision microporous filter

① The core part of the precision microporous filter is the filter element. The filter element is composed of special materials, which are suitable for wear and need special protection.

②. When the precision microporous filter has been working for a period of time, the filter element will contain a certain amount of impurities. At this time, the pressure drop will increase and the flow rate will decrease. The impurities in the filter must be removed in time and the filter element must be cleaned.

③. When removing impurities, pay special attention to the precision filter element, not to be deformed or damaged, otherwise, the filter element that is installed again, the purity of the medium after filtration cannot meet the design requirements.

U9彩票799cc④ Some precision filter elements, such as bag filter elements and polypropylene filter elements, cannot be used repeatedly.

U9彩票799cc⑤ If the filter element is found to be deformed or damaged, it needs to be replaced immediately.

U9彩票799cc2. Coarse filter microporous filter

① The core part of the coarse filter microporous filter is the filter element. The filter element is composed of the filter frame and stainless steel wire mesh. The stainless steel wire mesh is suitable for damage and needs special protection.

② After the filter has been working for a period of time, certain impurities have precipitated in the filter core. At this time, the pressure drop will increase and the flow rate will decrease. Therefore, the impurities in the filter core must be removed in time.

③. When cleaning impurities, pay special attention to the stainless steel wire mesh on the filter element not to be deformed or damaged. Otherwise, if the filter is installed, the purity of the filtered medium cannot meet the design requirements, and the compressor, pump, instrument and other equipment will suffer To destruction.

④ If the stainless steel wire mesh is found to be deformed or damaged, it needs to be replaced immediately.

U9彩票799ccThe microporous filter has high filtration accuracy, fast transition speed, less adsorption, no media shedding, acid and alkali corrosion resistance, convenient operation, and a wide range of applications, and its role is becoming more and more important.
