Central Military District - for pumping fluids in water -heated mines, dangerous for ejection of coal and gas
The “mine” is called pumps specially designed for use in the systems of water -heating mines and mines. They are distinguished by a high degree of explosive and fire protection, since such objects, in particular coal mines, are imposed on such objects.
Minute pumps are designed to pump neutral fluids with the following indicators:
- Temperature - up to 70 degrees;
- hydrogen indicator - pH+5.5–8.5;
- The content of sulfites and chlorides - up to 20 g/l;
- The content of solid particles is up to 1.5 % (up to 1 mm size).
Characterization of mine pumps
This type of pumps is a sectional, horizontal, multi -stage units with a one -sided wheels. Devices have the following advantages (compared to the central nervous system):
- The pressure per step (with a nominal feed of 300 m3/h) is 20–25 %higher;
- Reliability indicators are 3-5 times higher;
- Efficiency is 10-15 %more;
- The annual energy savings (with a duration of work 5500 hours per year) - 670 thousand kW/h
