How does the screw pump maintain and add any oil?
When the screw pump is parked, close the discharge stop valve and close the suction stop valve when the pump is fully stopped.
In addition, the spare screw, in the preservation of the best suspension method is used to avoid the deformation caused by uneven placement.
The connection of the shaft must be very good alignment; the work is best in the installation and positioning, so as to avoid the formation of deformation caused by the pipeline; connecting the pipeline should be independent of the fixed, as far as possible to reduce the involvement of the pump.
Screw pump due to the length of the work screw, poor rigidity, easy to cause bending, resulting in work disorders.
