Destination
Pumping units of the Central Administration are designed to pump desecrated water in the cooling system of the diesel generator of the diesel power station
design
The electric pumping unit consists of a pump and an electric motor mounted on a common foundation frame connected by an elastic coupling.
The pump consists of a case, a guiding apparatus, a worker’s wheel mounted on a shaft, a support bracket, a hull cover, a density body, a shaft compaction unit.
The pump body is made by welded ring. The pumped liquid enters the pump axis into the working wheel, then through the directing device to the pump housing and along the pressure pipe located perpendicular to the axis of the pump and directed vertically upward, to the pressure pipeline.
The pump rotor rotates in two ball -bearing supports.
The direction of rotation is clockwise, if you look from the side of the electric motor.
The shaft seal is carried out by a single or double end seal.
