Wlwa-50 Standing Reciprocation Vacuum Pump (oil free)

 Product DescriptionThe reciprocating pump operates on the positive displacement principle. The piston of a reciprocating piston pump goes back and forth in a cylinder. With the help of a connecting rod, the piston is connected to the crankshaft. The connecting rod moves as the crankshaft rotates, causing this piston to move. The crankshaft is connected to a rotating motor.With a suction valve and a delivery valve, the pump cylinder is linked to a suction pipe and a discharge pipe. The input and exit valves act as check valves, allowing only one direction of fluid flow. Through the input valve, the fluid is sucked into the cylinder. The outlet valve allows the fluid to exit the pump's cylinder.Main features1. Compact structure design, good rigidity, even force on moving parts, reducing the wear of moving parts and prolonging service life.2. Compared with other pumps of the same specification, it saves electricity by 1/3, cooling water can be used twice, and the floor space is reduced by 2/3;3. In the crankcase, the oil pump is used to force oil supply, with better lubrication effect.4. Smooth running, low vibration, low noise5. Because of the oil-free lubrication, clean vacuum can be obtained, which rejects the pollution of the process system by air reflux after temporary stop;6. Add recovery device, can recover the liquid in the system (such as alcohols), can also recover the gas in the system (such as hydrogen chloride into hydrochloric acid), such as adding vacuum puff collector, can also extract a small amount of dust;7. In the process of use, no need to add lubricant, easy and simple maintenance. ApplicationsWLW series oil-free vertical vacuum pump is the main equipment to obtain rough vacuum. It adopts unique technical structure, with better performance and more convenient use. It is also the replacement product of W type pump. It is widely used in vacuum distillation, vacuum drying, vacuum filtration, vacuum crystallization, vacuum smelting, vacuum infiltration and other industrial sectors such as petrochemical, pharmaceutical, food smelting, electronics, etc. to extract gases such as atmosphere, water vapor, chlorine, hydrogen chloride, sulfur dioxide, etc Technical dataModelWLW -50WLW -70WLW -100WLW -150WLW -200WLW -300WLW -400WLW -600WLW -1200Pumping volume L/s50701001502003004006001200Vacuum mmhg202020202020202020Rotational speed r/min320380350310300300300300300Electric power KW45.57.511152228.53745Inlet and exhaust caliber5050100100125145145180220Pump temperature rise ° C≤40≤40≤40≤40≤40≤40≤50≤50≤50Noise qB(A)≤70≤70≤70≤70≤70≤70≤85≤85≤85Inlet and outlet jointG1/2G1/2G1/2G1/2G1/2G1/2G1G1G1Weight Kg5005206008009001200180026003500 Pressure diagramAdditional Notes:1.
