Screw pumps are divided into single screw pump, twin screw pump and triple screw pump.The single screw pump is mainly composed of a screw rotor and a rubber stator. The motor drives the rotor to rotate, and the rotor and the stator form a dynamic closed volume cavity. As the helix moves forward, it will achieve the purpose of conveying the medium.

1. The flow rate of single screw pump is proportional to the rotational speed, and the automatic adjustment of flow can be realized by using speed regulation mechanism.2. The compound design of sealing function can realize the transformation and application of many kinds of sealing forms.3. The compound design of flange and bearing can realize the reverse transportation of the product in a short time.

1. Gear pump generally suction 5 meters more than 5 meters need to install bottom valve.2. Check whether the oil inlet is leaking or not, the leakage gear pump has no suction stroke.3. The rotation direction is wrong, it is right to stand on this side of the motor to rotate clockwise.4. If the suction pipe is blocked or the valve is closed, open the valve and check whether the dust cover is open.5. Check whether the rotation is flexible before booting. If there is a dead point, please adjust the concentricity.

The screw pump belongs to the volumetric rotor pump, which absorbs and discharges the liquid by the displacement of several sealing cavities formed by the screw tooth profile and the pump sleeve. There is no theoretical leakage channel between the two adjacent sealing cavities in the screw pump, which is called the strictly sealed screw pump, on the contrary, it is not strictly sealed screw pump.

The high -viscosity pump can transport high concentrations, without particles or medium containing some small particles. This is difficult to achieve other pumps, but it is very easy for high viscosity pumps.

The circular arc gear is in continuous contact between the two meshing tooth profiles, which will not produce oil trapping phenomenon, which completely solves the phenomenon of vibration, noise and bearing load increase of involute gear pump due to oil trapping phenomenon.
