About oil-free vertical reciprocating vacuum pumps

WLW series oil-free vertical vacuum pump principle:

WLW series oil-free vertical vacuum pump is mainly composed of mechanical transmission, mechanical air suction oil insulation part, mechanical transmission part is divided into crank and connecting rod mechanism, driven by the motor pulley, and then through the crankshaft, connecting rod, cross head to the piston, from the circular movement of the pulley into the linear movement of the piston. The mechanical pumping part of WLW series oil-free vertical vacuum pump mainly relies on the reciprocating movement of the piston in the cylinder to complete. The piston in the cylinder has a piston ring to ensure the gas seal of the two ends of the cylinder separated by the piston.

WLW series oil-free vertical vacuum pump piston in the cylinder to do reciprocating movement, constantly change the volume of the cylinder at both ends, one end of the volume to expand the suction gas, the other end of the volume to reduce the discharge gas. The combined action of piston and air valve completes the suction and exhaust function periodically. The oil trap and inflation chamber separate the mechanical transmission part from the gas flow part to prevent oil from leaking into, or into, the cylinder. When aspirated recovery is required, the gas can be filled into the inflation chamber. To prevent air leakage into the cylinder and affect the purity of the gas.

WLW series oil-free vertical vacuum pump Features:

1, oil-free vertical vacuum pump limit high vacuum degree (4.5-15mmHg).

2, oil-free vertical vacuum pump is filled with polytetrafluoroethylene piston ring, to ensure that the cylinder does not need lubricating oil can operate normally, to avoid oil pollution, waste and forget to refueling caused by accidents.

3, oil-free vertical vacuum pump can change the material of the accessories for pumping corrosive media.

4, oil-free vertical vacuum pump energy saving, water saving, save floor space.

5, oil-free vertical vacuum pump cylinder, piston ring, crankshaft, cross head of the average wear rate is greatly reduced, extend the service life, long service life.

6. Oil-free vertical vacuum pump eliminates shear wave bad vibration and reduces noise.

7. Simple and beautiful appearance, easy operation and maintenance.

WLW series oil-free vertical vacuum pump application:

WLW series oil-free vertical vacuum pump is the replacement of W series reciprocating vacuum pump, is the main equipment for obtaining crude vacuum. The complete isolation of crankcase and cylinder is realized due to the use of full sealing device. In addition, the piston ring uses a self-lubricating material to achieve advanced oil-free lubrication. Because there is no sewage discharge, WLW series oil-free vertical vacuum pump is especially suitable for vacuum distillation, vacuum evaporation, vacuum drying, vacuum concentration, vacuum impregnation and other processes in chemical, pharmaceutical and food industries.

It is especially suitable for applications in clean high vacuum or clean gas recovery environments. WLW series oil-free vertical vacuum pumps overcome the pollution caused by the need for lubricating oil.
