Horizontal pumps PGN
- centrifugal, horizontal, console, one-stage, with an axial supply and tangential removal of working liquid. Units are manufactured on the basis of the unified running racks.
Are intended for pumping of various abrasive hydromixes (suspension of ores, a pulp) on the basis of technical water with a density no more than 1600 kg/m ³, having firm inclusions up to 6 mm in size, volume concentration of which does not exceed 370 g/dm ³, with a temperature from 5 to 70 °C, with rn from 5 to 11 at the enterprises of the metallurgical, oil and gas industry.
Working environment - the ore suspension representing hydromix of particles of the processed ore with technical water and special additives.
The electric pump unit consists of the pump and the electric motor installed on the support plate (frame). The torque from the electric motor to the pump is transmitted through the elastic coupling or system of pulleys.
Options of execution of the driving wheel: opened or closed.
On forward and back disks of the driving wheel otboyny shovels are executed. Otboyny shovels protect areas of the most intensive wear, prevent hit of abrasive particles in bosoms between a wheel and the case, reduce axial loads of bearing support and reduce pressure before consolidation of a shaft.
The rotor of the pump rotates in two bearing support of swing. Greasing of bearings depending on a design of the pump can be liquid or jellied.
Options execution of trailer consolidation of a shaft: unary or double stuffing ("With" or "SD"). Also in addition hydrodynamic consolidation can be applied to improvement of operating conditions of an epiploon.
The raised service life of knot of omental consolidation will be reached application on the protective plug of a shaft of a special wearproof ceramic covering (on the basis of Al2O3). As stuffing the stuffing of production of the German firm "Propak" possessing the improved stability by hostile and abrasive environment, simplicity of cutting and convenience of installation, long service life can be applied to severe conditions of functioning of omental knot.
