IMO screw pump The pump is used to transport high viscosity, high temperature, corrosive or flammable and explosive media. Screw pump Different interface types of can be selected according to different application fields and fluid characteristics. This article will introduce five commonly used interface types and their application scope.

1、 The flange connection flange interface is usually used in the case of large flow. The common pressure grades are PN16, PN25, PN40 and other different materials, such as carbon steel and stainless steel, can be selected according to the standard. It is applicable to fluid with medium temperature between - 20 ℃ and+200 ℃ and viscosity less than 760cst.

2、 Clamp connection The clamp connection is suitable for transporting low viscosity, volatile media, such as gasoline, liquefied gas, etc. Its structure is simple, easy to disassemble and maintain, but it is suitable for low pressure occasions, usually not more than 2.5MPa. The medium temperature is between - 20 ℃ and+200 ℃.

3、 Threaded connection is suitable for screw pump with small volume, ALLWEILER screw pump The conveying flow is small, such as vehicle mounted screw pump, test equipment, etc. Inch thread or metric thread is usually used, and the material and scope of application are the same as those of flange interface, but the pressure rating is lower.

4、 Pipe clamp connection pipe clamp interface is suitable for occasions with small flow, medium temperature is between - 20 ℃ and+200 ℃, and is suitable for occasions with high hygiene requirements, such as pharmaceutical, food processing, etc. The pipe clamp connection can be easily disassembled and installed to meet the sanitary requirements of cleaning, disinfection, etc.

5、 Mixed connection of flange and pipe thread is often used for screw pumps with special requirements or customized. Different connection methods can be used to facilitate installation and maintenance according to the use needs, and can also better adapt to different media characteristics.

In short, screw pump IMO agent The different interface types of the pump can be selected according to the requirements of the use occasion, medium temperature, viscosity and pressure, so as to ensure the safe, stable and efficient operation of the pump. Each interface type has its scope of application and special advantages. Users should select the most appropriate interface type according to actual needs.
