Universal three-screw pump with wide application

Product Features:

1.The screw units is rotating along with the external prime mover.

2.The spiral groove of the screw opens periodically,and the volume of suction cavity increases,resulting into a vacuum.

3.The medium is absorbed into the spiral groove and sealed in the spiral groove.

4.Along with the rotation of screw,the medium moves toward the outlet along the axial line of the screw.

5.The medium is pumped out.This is the operating principle of screw pump.


Working principle:

The screw rotates with the external prime mover,

The spiral groove of the screw opens periodically, and the volume of the suction chamber increases to form a vacuum.

The medium is sucked into the spiral groove and sealed by the spiral groove,

With the rotation of the screw, the medium moves along the screw axis to the outlet along the spiral groove.

Finally, the medium is discharged from the pump, which is the working principle of HSN triple screw pump.


Performance Viscosity:3.0 ~ 1500 mm2/s

Flow:5 ~ 5300 L/min

Maximum Pressure:4.0 Mpa

Maximum Temperature:150 ℃

 

Tri-screw pump is formed by the pump body and screw. When the active screw rotates, it drives the driven screw which engages with it to rotate together. The meshing space of the screw at one end of the suction chamber 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 form a sealing chamber, the liquid moves continuously along the axis in each sealing chamber until it is discharged from one end of the cavity. At this time, the meshing space of the screw at one end of the discharge chamber is gradually reduced, and the liquid is discharged. The working principle of the three-screw pump is similar to that of the gear pump, except that the gear is replaced by the screw in structure. The table shows the characteristics and application range of various screw pumps. The flow and pressure pulses of the three-screw pump are very small, noise and vibration are small, and it has self-priming ability, but screw processing is difficult. There are two types of pumps: single-suction and double-suction, but single-screw pumps only have single-suction. Tri-screw pump with valves (single screw pump does not need to be equipped) to prevent damage to the pump or prime mover due to some reason, such as blockage of the discharge pipe, which causes the outlet pressure of the pump to exceed the allowable value.
