Dry screw vacuum pump is an upgraded product of oil seal vacuum pump. Its suction and discharge capacity can wash away a large amount of water vapor and discharge a small amount of dust gas at the same time. Compared with traditional vacuum pump products, it is more in line with the production requirements of energy conservation and environmental protection.
Dry screw vacuum pump of advantages
The number of parts of this kind of vacuum pump is relatively small, there are no easily damaged parts, the service life is long, the operation is simple, and the power balance is very good. The inertia of oil-free screw vacuum pump is relatively balanced and can maintain balance under high-speed operation. It also has the advantage of forced gas transmission, that is, in a relatively wide pressure range, its pump speed can continue to be at a relatively high level, and its exhaust volume is basically not affected. In addition, due to the relatively small gap between the rotating teeth of the machine, some corrosive and harmful gases can be pumped away during operation, which has the effect of purifying the environment.
How to adjust the clearance of dry vacuum pump
1. the adjustment of the axial clearance of the machine is mainly made by adjusting the bearing adjusting shim, which is usually adjusted before leaving the factory, and generally does not move after leaving the factory.
2. For a new pump that has not been worn, open the transmission gear first, and then loosen the gear compression sleeve. Pay attention to manually adjust the clearance at the threaded sleeve, and then retighten the gear, so as to adjust the relative clearance at the threaded sleeve.
3. Several screw vacuum pumps are worn, and most of them cannot be used normally by adjusting the clearance. At this time, the best solution is to replace the machine parts.
Before the dry screw vacuum pump machine runs, it is necessary to adjust the clearance between its internal teeth, which can well solve many problems existing in the production process.
