Zyb3/3.0 Slag Pump Structure and Starting Notes

ZYB3/3.0 slag oil pump is a hard tooth surface residue gear oil pump.

The working principle of ZYB3/3.0 slag oil pump is that when the active screw rotates, it drives the engaged driven screw to rotate together, and the meshing space volume of the screw at one end of the suction cavity increases gradually and the pressure decreases.

The liquid enters the meshing space volume under the action of pressure difference.

When the volume is increased to the maximum to form a sealed cavity, the liquid is continuously moved along the axial direction in one sealed cavity until one end of the discharge cavity.

At this time, the screw meshing space volume at one end of the discharge cavity is gradually reduced, and the liquid is discharged.

What should we pay attention to before starting ZYB3/3.0 slag oil pump?

1. Make sure that the connection between the suction pipe section and the instrument connector is kept sealed.

2. When ZYB3/3.0 slag oil pump is started for the first time or is not started for a long time, Portebon should fill the suction chamber with medium first and manually rotate the pump shaft for several revolutions before starting.

To prevent the stator and rotor dry friction, damage to the stator or reduce the suction energy of the pump

3, single screw pump before starting the pump sleeve layer should be heated, in order to reduce the viscosity of the residual medium in the pump.

4. Check the steering of the prime mover of the pump to prevent reversal.

5. Before starting, it is necessary to ensure that the pipe is unblocked, so it is necessary to open the valves on the inlet line and the outlet line
