W-type reciprocating vacuum pump features

W-type reciprocating vacuum pump has been widely used in the industrial sector, its role is also more obvious, W-type reciprocating vacuum pump also created its characteristics in the vacuum distillation, evaporation, crystallization, drying and Filtration, Vacuum Metallurgical Industry in the degassing, the role of the electrical industry in the field of infiltration W-type reciprocating vacuum pumps, is to obtain a rough vacuum one of the main equipment, which is characterized by the container from the closed or in the reaction Vacuum or other gas is evacuated, but it is not suitable for pumping corrosive gases or gases with hard particles of ashes. W-type reciprocating vacuum pump W-type reciprocating vacuum pump structural features: 1, W-type reciprocating vacuum pump mechanical transmission parts and gas circulation. Mechanical transmission part of the entire structure of the original contained in a closed body, the crankshaft is supported on both sides of the body tapered roller bearings. 2, W-type reciprocating vacuum pump equipped with a large pulley at one end to drive the transmission part. The connecting rod connects the crankshaft journal and the crosshead. One end of the piston rod is screwed into the screw hole of the crosshead and the other end is mounted on the cone hole of the piston and fixed with a nut. 3, W-type reciprocating vacuum pump motor and mounted on the shaft of the small pulley through the triangular tape driven crankshaft rotation, so through the role of the connecting rod and the crosshead, the piston in the cylinder for reciprocating motion. 4, W-type reciprocating vacuum piston rod connecting rod mechanism in the body movement, the oil pool of oil splash to lubricate bearings, crankshaft neck, crosshead and slide and other friction surface. In order to facilitate the inspection and maintenance of transmission, the body with detachable door on both sides and the back cover, the rear cover is equipped with oil windows to indicate the body oil tank height. W reciprocating vacuum pump is the necessary equipment to get the vacuum in the society at present. It can be used for evaporative crystallization and drying filtration in the fields of pigment, plastic, food, pharmacy, etc .; it can be used for concrete work in construction; in the metallurgical industry, it can make vacuum Gas and other departments need low pressure, low temperature operation. For people's production, life plays a very important role. Related Articles: Micro-vacuum pump and the difference between a large vacuum pump Which brand of micro-vacuum pump is good

Also known as electronic chemical materials. Generally refers to the electronics industry uses specialized chemicals and chemical materials, that is, electronic components, printed circuit boards, industrial and consumer production and packaging of various chemicals and materials. It can be divided into substrates, photoresists, electroplating chemicals, packaging materials, high purity reagents, specialty gases, solvents, pre-cleaning dopants, flux masks, acids and etchants, electronic adhesives and auxiliary materials Other categories. Electronic Chemicals with many varieties, high quality requirements, small dosage, demanding on the cleanliness of the environment, product replacement fast, large capital investment, higher value-added products, etc., these characteristics with the development of micro-processing technology more and more obvious.

Electronic chemicals, also referred to as electronic chemical materials, refer to the fine chemical materials that are used in the electronics industry. The electronic chemicals are a kind of special chemicals. As far as the properties of the production process are concerned, they belong to the fine chemical industry. In terms of product use, Belongs to the electronic material industry. According to the classification standard of China's national economy, the electronic chemicals industry belongs to "Specialized Chemical Products Manufacturing Industry" (2662); according to the "Guidelines for Industry Classification of Listed Companies" promulgated by China Securities Regulatory Commission in April 2001, it belongs to "Specialized Chemical Products Manufacturing Industry" C4360 ). They include integrated circuits and discrete device chemistries, such as chip production photoresist, ultra-clean high-purity reagents, ultra-clean high purity gas, plastic packaging materials; color TV with chemical materials, such as color phosphor, CPT Supporting the water-soluble resist, high-purity inorganic salts, organic films, etc .; chemical materials used in printed circuit boards, such as dry film resist, ink, chemical and electroplating copper plating solution and its additives, surface mount process conductive paste , Cleaning agents, liquid solder resist photoresist, adhesive patch, conductive adhesive, solder paste, pre-coated flux, clean and water-based process flux; liquid crystal display devices with chemical materials, such as liquid crystal, photoresist , Oriented films, adhesives, slurries, electrolytes, films and encapsulants, polarizers, etc .; polishing materials, ect.
