The conveying medium and structure principle of the screw pump

The conveying medium and structure principle of the screw pump
Screw pump conveying medium: liquids of various viscosities, especially viscous and difficult-to-transport media. Various concentrations of liquids and separately dehydrated dry materials. Liquids containing solid particles, fibers, and suspended matter. Mixtures of liquids, gases, and solids, sensitive liquids that cannot be stirred, sheared, or plundered.

Operational features of single screw pump: It has a wide range of adaptability and can transport all active media and even inactive materials. Flow, pressure and stability, no pulsation. The output flow can be changed by changing the rotation speed, which can be used for metering and dosing. Strong suction capacity, low operating noise, no leakage and no temperature rise.
Regarding the options of the single screw pump: the correct selection is the key to obtaining the best use effect. In order to meet the working requirements of different physical and chemical properties of the medium, we propose: the user submits the pump working data, and our company professionals select and recommend it. Later recognized by the user.

The structural principle of the screw pump: the magnetic drive of the key component of the screw pump is composed of an outer magnetic rotor, an inner magnetic rotor and a non-magnetic barrier sleeve. When the motor drives the outer magnetic rotor to rotate, the magnetic field can penetrate the air gap and non-magnetic material, and drive the inner magnetic rotor connected with the impeller to rotate synchronously, complete the non-contact transmission of power, and convert the dynamic seal into a static seal.

The screw pump adopts the advanced external mixing axial return pump body structure design. The pump body is composed of a suction chamber, a liquid storage chamber, a volute, a return hole, and a gas-liquid separation chamber. After the pump is started, under the action of centrifugal force, the remaining liquid in the suction chamber and the air in the liquid inlet pipeline are mixed by the impeller to form a gas-liquid mixture. , the air is discharged from the pump outlet. The drive equipment of the magnetic self-priming pump adopts an active magnet coupling directly mounted on the motor shaft, and the impeller on the rotor assembly is directly driven to rotate by the magnetic force, and the pump cavity is completely closed, and there is no leakage at all.
