IMO screw pump It is a common industrial pump, suitable for various process applications, including petroleum, chemical, pharmaceutical, food and beverage, paper and other industries. They are efficient, reliable and corrosion resistant, and can be used to transport various fluids, including high viscosity liquids, corrosive liquids and solid particle suspensions.

IMO Screw pump The main accessories include screw, rotor, stator, shaft sleeve, bearing, seal, etc. Screw is the core part of the pump, which drives the movement of liquid through rotation. The rotor and stator form the working cavity of the screw pump, which are respectively installed in the rotor and stator cavity of the pump to form the sealing cavity of the liquid. The shaft sleeve and bearing are used to support the rotor and stator of the pump and ensure their smooth and accurate movement. Seals are used to prevent liquid from being pumped out of the pump body.

In addition to the above accessories, the alternative scheme of IMO screw pump is also one of the important research points. At present, commercial alternatives in the market can be divided into the following categories:

Jet Pump: Jet pump is a device that uses the principle of high-speed fluid injection to deliver liquid. IMO agent It produces negative pressure under Bernoulli principle by injecting high-speed fluid into the liquid, so that the liquid is sucked into the air mixing device and then transported to the target position. The jet pump is suitable for occasions with low liquid requirements, and has no rotating parts, so the maintenance cost is low.

Submersible pump: Submersible pump is a kind of pump integrating motor and infusion part, which is usually used in sewage treatment or pump equipment. Its infusion part is usually composed of a centrifugal pump or a plunger pump, which can replace the IMO screw pump for liquid delivery. Because the submersible pump is an integrated design, ALLWEILER And it is usually located in the liquid, so no additional seals are required.

Diaphragm Pump: Diaphragm pump is a kind of pump that uses the elasticity of the diaphragm to deliver liquid. By changing the shape of the diaphragm, the liquid is sucked in and discharged from the pump body, thus realizing the transmission of liquid. Diaphragm pump is suitable for conveying liquid with high requirements for pump materials, because the liquid has no direct contact with pump materials.

Centrifugal pump: Centrifugal pump is a pump that uses centrifugal force to drive liquid. ALLWEILER screw pump It generates centrifugal force by rotating the impeller to push the liquid to the pump body outlet. Centrifugal pump is a common pump, which has the characteristics of small size, low price and simple maintenance, and is suitable for conveying low viscosity liquid.

In general, the accessories of IMO screw pump include screw, rotor, stator, shaft sleeve, bearing and seal, which ensure the normal operation of the pump and liquid delivery. At the same time, there are many alternatives in the market, such as jet pump, submersible pump, diaphragm pump and centrifugal pump, COLFAX agent Appropriate alternatives can be selected according to the needs of specific scenarios.
