Vacuum pump filter is a vacuum pump in the filtration equipment, filter is an important working part of the filter effect is mainly depends on the performance of the filter. So how to maintain and maintain the vacuum pump filter? How to maintain the imported vacuum pump filter? Vacuum pump filter maintenance methods Vacuum pump filter, the main filter in the operation of the vacuum pump in three forms: 1, air intake filter (which can effectively prevent the solid particles and fine ash is sucked into the vacuum pump to reduce mechanical wear and tear to improve operational reliability in the extension of the pump life But also can effectively protect the system components.) 2, the exhaust filter (taking into account the exhaust resistance, dust holding capacity, oil and gas separation performance, the three requirements of the legislation to achieve optimal balance of different internal and external locations to use different materials In order to achieve different separation purposes) 3, the oil filter (for the vacuum pump oil filter to extend the use of oil mainstream filter, installed in the oil Road) Use and maintenance methods: In the cleaning replacement, there are many people Not essentials, often spent in vain, but did not receive better results. 1, Loosen the knob bolt to separate the filter housing from the head. Be careful not to lose rubber seals and fibrous washers. 2, carefully remove the spring and felt pads, and then remove the paper over the core. 3, with a brush to remove the filter crease in the dust and foreign matter, and then gently tap the hand so that the remaining dust fall, wipe the dust on the inner wall of the shell and fiber mat. 4, according to the order of disassembly will have been cleaned or a new filter cartridge back.

Organic raw materials
Organic raw materials that are oil and natural gas as raw materials of petrochemical, food fermentation alcohol or solvent industry, coal gasification of raw materials and dry distillation of coal tar prepared or fractionated from a variety of organic chemical products industry. In China's organic chemical industry first coal-fired calcium carbide route, coal gasification of methanol, formaldehyde route and recovery of coal tar benzene, naphthalene, anthracene and other routes and food as Raw Material fermentation distillation system developed alcohol.
Basic organic chemicals used in the main raw materials are: hydrogen, carbon monoxide, aliphatic hydrocarbons (methane, ethylene, acetylene, propylene, C4 above the aliphatic hydrocarbons), aromatic hydrocarbons (benzene, toluene, xylene, ethylbenzene) and so on. From the crude oil, petroleum fractions or low-alkane pyrolysis gas, refinery gas and gas, after separation treatment, can be made for different purposes of the aliphatic hydrocarbon feedstock; from the catalytic reforming of the reformed gasoline, hydrocarbon cracking pyrolysis gasoline As well as coal dry distillation of coal tar, can be separated from the aromatic feedstock; the appropriate petroleum fractions can also be used directly as raw materials for certain products; from the wet natural gas can be separated from methane other than the lower alkanes; from coal gasification and natural gas, refining The conversion or partial oxidation of the plant gas, the petroleum fraction or the crude oil can be made into syngas; the calcined calcium carbide, or the natural gas or naphtha, can be used to produce acetylene. In addition, raw materials can be obtained from agricultural and sideline products.
Organic raw materials products are widely used, can be divided into three aspects: First, the production of polymer products for the raw materials, that is, polymerization of monomers; Second, for other organic chemical industry, including fine chemical products, raw materials; For solvents, refrigerants, antifreeze, gas adsorbents and so on. Basic organic chemical industry is the basis for the development of various organic chemical products, is the main component of modern industrial structure.Organic Raw Material
