Screw-roots Vacuum Pump Units
- Screw-roots Vacuum Pump Units
■ Screw Roots unit features
1.Environmental assessment is passed. Using Dry screw vacuum pump，the recycled material has high purity and can be 100% recycled without pollution, and no sewage treatment is needed in the later stage;
2.Save energy. Compared with energy saving of more than 40%, water saving is more than 90%;
Vacuum unit power
| Unit type | Motor Power | Annual electricity consumption (8 hours per day) | Annual electricity bill (0.5 yuan per kWh) |
| Water ring roots unit | 75KW+7.5KW=82.5KW | 240900度 | 120450元 |
| Screw-roots unit | 18.5KW+11KW+4KW=33.5KW | 97820度 | 48910元 |
It can save 143,080 degrees of electricity and reduce the cost of 71,240 yuan per year;
3.The vacuum is high.The ultimate vacuum of Water ring roots unit is 200Pa.The ultimate vacuumof Screw-roots unit can reach 1Pa, which greatly shortens the reaction time;
4.Greatly improve product quality and purity. The water content of the product can be reduced from the original 0.4% to the current 0.0012%;
5.Adapt to the environment and have strong capabilities. Because the summer water temperature high water ring pump can not reach the pre-vacuum demanded by the Roots pump, the water ring Roots unit can not start, andThis situation of Screw-roots unit can be completely avoided;
6.Long lasting. The gas contact parts are coated with Teflon, nickel and Hastelloy to improve the corrosion resistance and wear resistance of the pump;
7.Low noise and low vibration.The two rotors of Screw vacuum pump are subjected to strict dynamic balance correction, and a reasonable gap is left between the two rotors. Therefore, the rotor does not collide when the pump is working, and the operation is stable and the noise is low;
8.Low failure rate and easy maintenance. The design structure is simple, no mechanical seal is used, no frequent failures due to pollution, easy maintenance and repair.
■ Roots screw vacuum pump unit Typical applications: chemical and pharmaceutical, semiconductor, solvent recovery, molding, crystallization, dry etching, sputtering, steam recovery, high-altitude simulation
