IMO screw pump And centrifugal pump are two commonly used industrial pump categories, and they have some differences in performance and application. The following is a comparison of the working principle, performance parameters and application fields.

First, in terms of working principle, Screw pump The liquid is pumped into the pump from the inlet through the rotating movement of the screw, and the liquid is pushed towards the outlet along the spiral groove of the screw through the spiral shape of the screw. Centrifugal pump sucks liquid into the pump from the inlet through the rotating movement of the rotor, and then pushes the liquid to the outlet through centrifugal force. The working principle of screw pump is more suitable for conveying liquid with high viscosity and solid particles, while centrifugal pump is suitable for conveying clean liquid.

Secondly, there are obvious differences between the two in terms of performance parameters. The performance parameters of screw pump mainly include flow, head, power and efficiency. Because the screw groove of the screw pump is wide and the screw surface is smooth, the efficiency of the screw pump is relatively high, and because of its synergistic multi screw structure, its delivery flow is generally large. The performance parameters of centrifugal pump include flow, head, power and efficiency. Due to the structural characteristics of centrifugal pump, its head is usually large, which is suitable for conveying high head liquid. IMO agent

In addition, screw pump and centrifugal pump are also different in application field. Screw pumps are suitable for conveying liquids with high viscosity and solid particles, such as various dense liquids, sludge and suspended particles. Common applications include chemical, petroleum, paper making, food and other industries. Centrifugal pumps are suitable for conveying clean liquids, such as water, oil, air, etc. Centrifugal pumps are widely used in construction, water supply, drainage, agriculture and industry.

In addition, there are some other differences between the two. Screw pump adopts screw structure, so it has low noise, low vibration, simple maintenance and relatively high price during operation. Centrifugal pumps are relatively cheap, but they are noisy and vibrate significantly during operation, requiring more frequent maintenance. COLFAX agent

In a word, screw pump and centrifugal pump have some differences in performance and application. Screw pump is suitable for conveying liquid with high viscosity and solid particles. It has the characteristics of high efficiency and large flow. Centrifugal pumps are suitable for conveying clean liquids, with large lift and wide application fields. Both of them have their own characteristics and advantages in structure, working principle, performance parameters and application fields. When they are used, they need to choose the appropriate pump type according to the specific situation. CIRCOR SECCO
