Oil, fuel, and air filters are used to filter out mechanical impurities in the oil, fuel, and air entering the engine, and protect the engine crankshaft connecting rod movement, the precision coupling parts of the fuel injection system, and the cylinder liner piston ring from abnormalities. Wear and tear is an important component (attachment) that enables the engine’s economic indicators, power indicators, reliability and emission indicators to function normally. With the gradual implementation of emission regulations, engine technology advancements have put forward new and higher requirements for filter products, which increasingly shows the importance of filters for engine matching.
Tsheb lim ntawv yog ib daim ntawv tshwj xeeb kev lag luam tshwj xeeb uas siv los ua cov tshuab lim cua hauv tsev mini. Nws yog tus cwj pwm los ntawm kev pom kev ua haujlwm siab thaum tswj cov cua tsis muaj zog. Feem ntau, qhov pom kev ua haujlwm ntawm cov ntawv lim cua hauv tsev yog 95-98%, thaum lub tsheb lim ntawv tuaj yeem ncav cuag ntau dua 99.5%. Automotive lim ntawv yog dav siv hauv tsheb, locomotives thiab engineering plua plav tshem tawm cov cuab yeej.
1. Khoom txhais
Tsheb lim ntawv los yog tsheb kev lag luam lim ntawv yog ib hom ntawv lim uas tau coated thiab impregnated. Nws yog tsuas yog siv los ua cov khoom siv lim dej zoo rau lim impurities hauv huab cua, roj thiab roj.
Industrial filter paper includes air filter paper, oil filter paper, fuel filter paper, etc. The weight of a gram is between 120 g/m² and 145 g/m². The filter element made of filter paper has the advantages of high filtration efficiency, low cost and light weight.
2. keeb kwm kev loj hlob
Many filter materials, such as felt, cotton yarn, iron wire, oil bath, etc., have basically been replaced by impregnated paper filters. With the rapid development of the automobile industry, paper as a filter material has been widely used in the world’s automobile filtration industry and has a very broad development space. In 2004, the U.S. Economic Commission listed industrial filter paper as one of the top ten potential filter papers in the world.
Txij li thaum Tebchaws Meskas tau tsim cov dej cawv-soluble thermosetting phenolic resin impregnation txheej txheem rau tsheb lim ntawv hauv xyoo 1953, nws tau siv los ua ib qho impregnant hauv cov txheej txheem ntau lawm ntawm tsheb lim ntawv rau lub sijhawm ntev. Lub ntsiab zoo ntawm cov txheej txheem impregnation yog cov cuab yeej paub tab, dej tsis kam, thiab siab hardness ntawm cov ntawv lim.
3. Khoom nta thiab daim ntawv thov teb tsom xam
Lub tsheb lim ntawv yog ib qho ntawm cov khoom siv raw rau kev tsim cov khoom lim, uas muaj kev cuam tshuam tseem ceeb ntawm kev lag luam thiab kev ntsuas, kev tiv thaiv ib puag ncig, ntsuas kev nyab xeeb thiab kev pabcuam lub neej ntawm lub cav.
