Filters in industries such as petroleum, mining, chemical industry, food, medicine, machinery manufacturing, etc., exist in our daily life, the filtering of air conditioners, smoke, dehumidifiers, natural water and food to our livesQuality and safety plays an indispensable role.This article mainly introduces relevant knowledge about filters.
Filter price
The filter is actually a filter, which is generally made of metal or synthetic fibers. It is used for the separation of various fluid substances. Generally, corrosion resistance and antioxidant.The oblique filter is actually a slope filter, that is, the net above is a slope. The price is generally around 60 yuan.
Filter standard
1. Filter national standards: standard division of gas pipe type (1404), shrinkage diameter filter (1405), and full diameter filter (1406).The diameter of the foaming device is from 300mm to 6400mm, and there are two types of silk mesh of 100mm and 150mm.The new standard combines three types of installation forms of the gas pipe type, shrinkage diameter and full diameter type; proposes: SP, HP, DP, and HR four filter types and expand the type of material selection;Increased.
Filter specification
The application range of filters is so powerful, and the specifications of filters are naturally diverse.Generally speaking, the filter specifications are determined by the number of items -this parameter.The mesh refers to the particle size or thickness of the material. The scientific definition is the number of mesh in the area of ??the 1 -inch X1 inch, which is generally called the number of mesh of the filter.For example, 400 mesh means that the material can sieve with 400 mesh networks in a 1 -inch X1 -inch area.It can be seen that the larger the number of meters, the smaller the particle size of the material, and the more excellent filtering effect.In my countrys filter specifications, it mainly depends on whether the sieve size of the filter is matched with the number of meters.For example, the standard number of 4.75mm sieve holes is 4 meters, 0.85mm sieved standards are 10 mesh, 0.15mm sieve pores are 100 mesh, and the number of sieve periosteen per scaffolding at 0.045mm is 325 meters.The number of filters of other specifications can be referred to as the national filter specifications standard table.
Number of filters
The number of filters refers to the number of mesh per square mesh (CM2) silk mesh per square meter.The unit that is used to express the number of mesh products is holes/cm or line/cm.The country and regions of the British -made metering unit are used to express the number of silk mesh with holes/inch or line/inch.The number of mesons can generally illustrate the density between the silk and the silk of the silk mesh.The higher the mesh, the more dense the silk mesh, the smaller the mesh.Conversely, the lower the mesh, the thinner the silk mesh, the larger the mesh, such as 150 mesh/inches, that is, 150 mesh silk within 1 inch.The smaller the mesh, the worse the ink passes, the larger the mesh, and the better the ink passes.When choosing a silk mesh, you can select the wire mesh with different goals according to the accuracy requirements of the bearing.
