A, W-type reciprocating pump Model significance: W pump Model Description Second, W-type reciprocating pump Overview: W-type reciprocating pump (also known as the piston pump), a low-vacuum device to get one, it's the ultimate pressure is generally 1330 ~ 2660Pa Its relatively large pumping speed range from 50L / S to 200L / S, vacuum impregnation for petroleum, chemical, pharmaceutical, food, light industry, metallurgy, electrical and other industries, the molten steel vacuum, vacuum distillation, vacuum evaporation pumping gas, concentrated in vacuo, vacuum crystallization, vacuum drying, vacuum filtration and concrete operations, and other aspects of the vacuum. Does not apply to high oxygen extraction, there are explosive, corrosive to metal, and will pump oil from a gas containing dust particles and chemical reactions, does not apply to the transportation of gas from one container to another container, for pump use. W-type reciprocating pump with a small, simple maintenance, long life valves, etc., suitable for use in the higher pressure range. However, reciprocating pumps and WLW as wearing parts is very large, ongoing maintenance is relatively cumbersome. Three, W-type reciprocating pump Features: W-type reciprocating pump is one of the main vacuum device to obtain crude, which is used from a closed container or Fanyingguo vacuum pumping or other gases, it is not suitable for pumping corrosive gas or gas with hard particles of ash. W-type reciprocating pump structure consists of two major parts; 1, W-type reciprocating pump mechanical transmission part and a gas flow portion. The entire structure of the original mechanical transmission parts installed in a closed body, the body of the crankshaft is supported on both sides of the tapered roller bearing. 2, W-type reciprocating pump is equipped with a large end of the crankshaft pulley to drive the transmission part. The crankshaft connecting rod journal and crosshead connected. One end of the piston rod is screwed into the screw hole in the crosshead, and the other end attached to the tapered bore of the piston and the nut. 3, W-type reciprocating pump motor and a small pulley mounted on the shaft driven by the crankshaft rotation triangle tape, so that by the action of the connecting rod and the crosshead, the piston reciprocates in the cylinder. 4, W-type reciprocating pump rod-crank mechanism in the body during exercise, the lubricating oil to lubricate the bearings splash pool, neck crank, crosshead and slides and other friction surface. In order to facilitate inspection and repair transmission, body sides and rear doors with removable lid, covered in oil after the oil window to the instructions provided with the body height of the oil pool Kai Qing Pump Manufacturing Co., Ltd. is a company specializing in Shanghai research, manufacturing, production and sales of pumps technology companies.
