Brine mining gear pump a dedicated pump well deep well brine collected in western China, the structure of motor installed on the surface and the motor base is installed in thebackplane, the motor is installed in the motor seat, the motor shaft through a universalcouplingconnected with the drive shaft, drive shaft connected with the driving gear, driving gear and driven gear is installed in the gear box, driven gear and shaft connected andsealed at the junction of the pump shaft and gear box assembly shaft, the pumpmounted atthe pump inlet seat, and installed in the gear box, the pump Ministry of the upper and thetube connection fluid tube extends upward to the base plate and a fixed connection with the backplane. Advantages: motor placed in the brine wellhead, choose ordinary motor, no leaks, burned phenomenon. Connecting pipe to withstand the suspension pump tube to withstand the brine fluid delivery pump out the wellhead, the connecting pipe through thebrine solution, and the choice of carbon steel pipe exterior coating, anti-brine solutioncorrosion treatment. Out of the tube to use inexpensive non-metallic pipe, lower equipmentcost.
