Pumping SNN stations

Pumping SNN stations

Pumping SNN stations are designed to power the working fluid of hydraulic systems of mechanized vehicles of treatment complexes in mines and coal mines, including hazardous gas and dust. The area of ​​application of the station is mining with an angle of inclination of not more than 5 ° C. The environment is the slabs of mines and mines with a temperature from plus 5 to plus 35 ° C and relative humidity up to 98 % at a temperature of up to plus 25 ° C. Category of mines and coal mines for gas and dust - any.

The working fluid is a water-oil emulsion or other emulsion, allowed for use in hydraulic systems of mining equipment, with an additive concentration of 1.5% to 5%. The class of purity of working fluid is not lower than 17 according to GOST 17216 with the nominal subtlety of filtering 80 microns.

Type of climatic performance U5 according to GOST 15150.

Ensuring explosion protection

The electrical equipment of the station consists of serial electrical products designed to work in mines and coal mines, dangerous gas and dust.

"> The delivery set includes:
  • hydraulic tank (with a filter of the drain line and a node of the pneumohydractulator),
  • pump unit - 2pcs.,
  • The filter of the cluster line (with reverse washing),
  • Magistral pressure navigan Du25,
  • Magistral drainage hose hopp from DU32;
  • set of spare parts,
  • A set of tools and accessories,
  • Operational documentation.
