IMO screw pump It is a kind of equipment working with screw body, which pushes fluid from the inlet to the outlet. In many Screw pump In the selection scheme, select the most suitable screw pump to maintain its operating rate and performance, so as to maximize production efficiency. This article will provide some useful guidelines to help you choose the right screw pump.

Flow requirements

First, you need to determine the required traffic. The flow of screw pump depends on its diameter, length and screw pitch. Larger screw pumps tend to have higher flow rates, but are not necessarily more cost-effective. Therefore, you need to select the appropriate flow specification according to the specific use.

Pressure requirements

After determining the required flow, you need to consider the required pressure. The pressure of the screw pump is usually controlled by the screw pitch and speed of the pump. Closer pitch and lower speed usually result in higher pressure, while the opposite situation will result in lower pressure. When selecting screw pump, pay attention to the balance between flow and pressure to ensure the best performance.

Working medium

Screw pump can be used to transport various liquids or viscous substances. According to your specific working medium, you need to select a suitable pump. For example, screw pump can be used to transport sewage, oil, particles, dense materials, etc.

Temperature requirements

The temperature range of the screw pump also needs to be considered. Some materials are very suitable for high or low temperature applications, while others are only suitable for normal temperature applications. When selecting the screw pump, it is necessary to pay attention to whether it can work normally at the required temperature.

Material Science

    ALLWEILER The material of screw pump is one of the important considerations. Some pumps are made of materials such as plastic, cast iron and stainless steel. Pumps made of different materials have different advantages and disadvantages. For example, plastic pumps are less expensive but less stable than stainless steel pumps, while cast iron pumps are durable but heavier. When selecting a screw pump, you need to consider your working conditions and budget.

speed

Speed is also one of the factors to be considered when selecting screw pump. Higher speeds can achieve higher flow and pressure, but may also cause additional wear and damage. Therefore, it is necessary to balance the flow and performance to determine the most appropriate speed.

In general, several factors need to be considered when selecting a suitable screw pump. According to your specific use and requirements, you can choose the appropriate flow and pressure, the applicable working medium and temperature range, as well as the appropriate material and speed.
