With the promotion of vacuum pumps, there are more and more vacuum pump products on the market. Oil-free vertical vacuum pumps are one of the main types. What about oil-free vertical vacuum pumps? Let\'s take a good look at it today!
Principle of oil-free vertical vacuum pump
The oil-free vertical vacuum pump is mainly composed of a mechanical transmission part, a mechanical air extraction part and an oil separation part. The mechanical transmission part is divided into a crank and a connecting rod mechanism. From the circular motion of the pulley to the linear motion of the piston. The mechanical pumping part of the WLW series oil-free vertical vacuum pump mainly relies on the reciprocating motion of the piston in the cylinder. There are piston rings on the piston in the cylinder to ensure the airtightness of both ends of the cylinder separated by the piston.
When the piston of the oil-free vertical vacuum pump reciprocates in the cylinder, the volume at both ends of the cylinder is constantly changed, the volume at one end expands the intake gas, and the volume at the other end reduces the exhaust gas. The combined action of the piston and the air valve periodically completes the suction and exhaust functions. The oil separation chamber and the gas-ed chamber separate the mechanical transmission part from the gas circulation part to prevent oil from leaking into or being brought into the cylinder. When the suction gas is required to be recovered, the gas chamber can be filled with this gas. To prevent air leakage into the cylinder and affect the gas purity.
How about oil-free vertical vacuum pump
1. The oil-free vertical vacuum pump has a high ultimate vacuum (4.5-15mmHg).
2. Oil-free vertical vacuum pump Oil-free: The use of filled PTFE piston rings can ensure that the cylinder can operate normally without lubricating oil, avoiding oil pollution, waste and accidents caused by forgetting to refuel.
3. Oil-free vertical vacuum pump can change the material of accessories for pumping corrosive medium. The WLWF series is made of stainless steel or fluorine-lined, titanium material, and can resist corrosion of various acids, alkalis and organic solvents.
4. Oil-free vertical vacuum pump saves energy (33%), water (50%), and floor space (66%).
5. The average wear rate of oil-free vertical vacuum pump cylinder, piston ring, crankshaft and crosshead is greatly reduced, prolonging the service life and long service life (4-10 times).
6. Oil-free vertical vacuum pump reduces noise due to the elimination of shear wave inferior vibration.
7. Simple and beautiful appearance, convenient operation and maintenance.
Oil-free vertical vacuum pump application
Oil-free vertical vacuum pump is a replacement product of reciprocating vacuum pump and is the main equipment for obtaining rough vacuum. Due to the use of a fully sealed device, the crankcase and the cylinder are completely isolated; coupled with the use of self-lubricating materials for the piston rings, advanced oil-free lubrication is achieved. Because there is no sewage discharge, the oil-free vertical vacuum pump is especially suitable for vacuum distillation, vacuum evaporation, vacuum drying, vacuum concentration, vacuum impregnation and other processes in the chemical, pharmaceutical and food industries.
It is especially required to be used in clean high vacuum or in the environment where the gas needs to be cleanly recovered. WLW series oil-free vertical vacuum pump overcomes the pollution caused by lubricating oil.
