Three factors affecting the life of filter element

The water filter element is used in the filtration system to remove the particles and sundries in the system and ensure the cleanliness of the filtration system. The service life of the water filter element is an important problem in the filtration system, especially in the high pollution working conditions, the failure of the filter element and the resulting failure of the filtration system is particularly prominent. What are the main factors that affect the service life of the water filter element?



First, filtration performance of filter element



1. Filtration accuracy: filtration accuracy refers to the filtration capacity of filtration materials for different sizes of particle pollutants.



It is generally believed that the filtering accuracy is high and the life of the filter element is short.



2, the amount of pollution



The pollution capacity refers to the weight of particle pollution that can be accommodated by the unit area of the filter material when the pressure drop of the filter material reaches the specified quantity value during the test. The filter hole is susceptible to the deposition and retention of particle pollutants through the channel, so that the pressure difference increases. When the pressure difference reaches the larger value specified, the service life ends.



The direct parameter reflection of the end of the filter life is that the pressure difference between the upstream and downstream of the filter reaches the pressure of the bypass valve opening. At this time, the pollutant carrying capacity of the filter element also reaches a large value. If the pollution carrying capacity of the filter element is considered in the design and manufacture of the filter element, it is to improve the life of the filter element.



Second, the process parameters of the filter element



1. Wave height, wave number and filtration area



In the filter element shape size has been determined under the premise! Changing the wave height, wave number and other process parameters to increase the effective filtration area of the filter material as far as possible, can reduce the flux of the unit filter material surface and increase the pollution capacity of the whole filter element, improve the life of the filter element. By increasing the filtering area of the filter element, the service life of the filter element is often increased faster. If the wave number increases too much, the crowded folding wave will reduce the water flow space between the waves, making the pressure difference of the filter element increase! The time to reach the differential pressure alarm of the filter element is short and the service life is reduced.



2, the strength of the skeleton



In the filter element structure, it is very important that the skeleton of the inner and outer layers has a certain strength. The skeleton keeps the corrugate shape to prevent bending and supports the filter material to prevent fatigue failure.



Three, filter element in the process of water pollution



After the production of water filter element, its nominal service life has been decided by itself, but more important is how the user uses the water filter element, the installation and rational use of water filter to control the pollution of water filter element plays a certain role. For filter (filter) and filter service life of the original cost to the user using the product of the economy, improve the service life of filter element is not only a filter design and the manufacturer, and is a core users, both should be in the water quality of polluted channels, working condition of filter system and manufacturing parameters of filter filtration performance and technology aspects into consideration to improve the service life of the filter element.

rufio costume

I \'ve been making Halloween costumes for my brother for years, and the challenge this year is Rufio in the movie Hook. Here you will find all the steps to make this outfit and I hope you like it! Supply: Black artificial leather, black canvas fabric, fusible interface, red fabric, black thread, black embroidery thread, sewing machine, wood beads, embroidery needle, scissors, iron, drill pin, colored pencil and paper. I first watched the movie Hook and outlined the idea of how the jacket should be constructed. Once I had a decent sketch and had a good idea of how to make it, I started making the pattern. Because the dress was made for my brother, I used him as a model and put a few pieces of scrap cloth on him with a pin to make the shape of the jacket. Once the shape is implemented and all the seams are marked, I transfer this design to the paper pattern. Before I used any of my good fabrics, I made a sample jacket for the test fit. Once it was decided to fit, I started cutting th...

10 Tips to Ordering Kitchen Cabinets Online

1. Choose an established kitchen cabinet supplier Look for a supplier that's been around for some time. An established supplier will have years of experience and have gained plenty of valuable information about kitchen cabinets and kitchen design. That will make it easy for them to give you advice when it comes to choosing the right cabinets for your home. Also, a custom kitchen cabinet supplier that's been around for some time means the business is likely to be stable and enjoys a good track record. So you won't have to worry too much about being scammed into buying poor quality products. 2. Check the company's quality control system and manufacturing capabilities Find suppliers who actually make kitchen cabinets. Quality suppliers should be able to consistently produce products that meet or exceed customer expectations. The only reliable way to check a supplier's capabilities is to visit the production facility in person or through a third-party agent. Reputable ...
