The electric pumping unit consists of a pump and a drive engine installed on a common foundation frame or slab and interconnected using an elastic coupling. Pumps of VK, VKS and VKO - vortex, single -stage, horizontal, console.
Moving the liquid medium through the ring channel and giving it the necessary energy is carried out by a working wheel, which is a disk with radially located blades.
The dimensions of the hydraulic part change depending on the size of the pump, but the design of all pumps is the same. The working chamber of the running part of the pump is made in the housing and cover of the housing and is a ring channel reporting with the entrance and output pipes of the pump. The absorption and guide part of the channel are separated by a jumper (delay).
The working wheel is fixed on the shaft of the venarable, has the possibility of free movement in the axial direction. The holes available in the disk allow you to unload the working wheel from the axial forces.
The pump shaft rotates in two ball -bearing supports installed in the pump bracket.
To reduce the leaks of the pumped product into the environment in the pump housing, an oil filler is installed.
At the VKS pumps, the upper cap is attached to the output pipe, which provides the possibility of self -consumption.
In the pumping pumps of the ALC, the heating cover with the lid and the heating disk with the body form a heating chamber, into which steam or cooling liquid is supplied.
The direction of rotation of the rotor for the pump is indifferent, and is determined only by the position of the pipelines and the prerequisite for moving the fluid from the absorbing to the pressure pipeline along the large arc.
