W/WY Reciprocating Vacuum Pump
W/WY Reciprocating Vacuum Pump--Product overview
W/WY Reciprocating Vacuum Pump (also known as piston vacuum pump) is one of the equipment for obtaining low vacuum. Its ultimate pressure is generally 1330～2660Pa, and its pumping speed range is relatively large, from 50L/S to 200L/S, suitable for petroleum Vacuum impregnation, vacuum treatment of molten steel, vacuum distillation, vacuum evaporation, vacuum concentration, vacuum crystallization, vacuum drying, vacuum filtration and vacuum operation of concrete in the chemical, pharmaceutical, food, light industry, metallurgy, electrical and other industries In addition to gas. It is not suitable for pumping gas with high oxygen content, explosive, corrosive to metal, chemical reaction with pump oil, and gas containing particulate dust. It is also not suitable for transporting gas from one container to another. The container is used as a delivery pump. The W/WY Reciprocating Vacuum Pump has the advantages of small size, simple maintenance, and long valve life. It is suitable for use in a higher pressure range. But like the WLW reciprocating vacuum pump, there are many wearing parts, and the later maintenance is relatively cumbersome.

W/WY Reciprocating Vacuum Pump--Product features
W/WY Reciprocating Vacuum Pump is one of the main equipment to obtain rough vacuum. It is used to extract vacuum or other gases from a closed container or reaction pot. It is not suitable for extracting corrosive gases or dust with hard particles and gas.
The structure of W/WY Reciprocating Vacuum Pump consists of two main parts;
1. W/WY Reciprocating Vacuum Pump mechanical transmission part and gas circulation part. The entire structure of the mechanical transmission part is installed in a closed body, and the crankshaft is supported in tapered roller bearings on both sides of the body.
2. W/WY Reciprocating Vacuum Pump is equipped with a large pulley at one end of the crankshaft to drive the transmission part. The connecting rod connects the journal of the crankshaft with the crosshead. One end of the piston rod is screwed into the screw hole of the cross head, and the other end is installed in the cone hole of the piston and fixed with a nut.
3. W/WY Reciprocating Vacuum Pump motor and the small pulley mounted on the shaft drive the crankshaft to rotate through the triangular tape, so that the piston is reciprocated in the cylinder through the action of the connecting rod and the crosshead.
4. W/WY Reciprocating Vacuum Pump connecting rod crankshaft mechanism moves in the body, the lubricating oil in the oil pool is splashed to lubricate the friction surfaces such as bearings, crankshaft journals, crossheads, and slideways. In order to facilitate the inspection and maintenance of the transmission mechanism, detachable door covers are installed on both sides and back of the machine body, and oil windows are installed on the rear cover to indicate the oil level of the oil pool in the machine body.
W/WY Reciprocating Vacuum Pump--Working principle
The picture shows the working principle of the W/WY Reciprocating Vacuum Pump. The main components of the W/WY Reciprocating Vacuum Pump are the cylinder 1 and the piston 2 that reciprocates linearly. The piston is driven by the crank connecting rod mechanism 3 (including the crosshead). of. In addition to the above-mentioned main components, there are also important components such as the exhaust valve 4 and the suction valve 5, as well as auxiliary components such as the frame, the crankcase, the dynamic seal and the static seal.
