IMO screw pump It is a very common pump used to transport high-temperature liquid. This kind of pump is widely used in chemical, petroleum, metallurgy and other fields. In use, special attention should be paid to some problems to ensure its normal operation safety. Let's take a closer look at IMO Screw pump What should be paid attention to when transporting high-temperature liquid.

1、 Scope of application:

First of all, it needs to be clear that IMO screw pump is suitable for conveying high-temperature liquid, but its maximum temperature is also limited. In specific operation, pump rod pieces and sealing materials of different materials shall be selected according to different conditions. For many high-temperature liquids, the temperature resistance of IMO screw pump has reached 180 ℃, but for some ultra-high temperature liquids, higher level pumps may be required, such as magnetic pumps, two-phase flow pumps, etc.

2、 Heat protection measures:

Since the liquid handled by IMO screw pump is at high temperature, measures should be taken to prevent the pump body from being overheated, causing deformation of the pump body, or even mechanical failure. In actual use, the pump body temperature can be reduced to prevent excessive temperature. For example, using coolant or setting a temperature reducer, the cryogenic liquid around the pump body flows through the pump body to absorb the rest of the heat, thus reducing the temperature of the pump body.

3、 Sealing problems:

When IMO screw pump transports high-temperature liquid, special attention should be paid to the sealing problem, because sealing failure or leakage will affect the environment IMO agent Equipment and personnel bring serious hazards. If not maintained in time, it may cause fire or explosion, and even endanger personal safety in serious cases. Therefore, when using, special sealing method for high-temperature liquid shall be selected to effectively avoid leakage of pump body and other problems.

4、 Material selection:

Since the transportation of high-temperature liquid will have a destructive impact on equipment and materials, the IMO screw pump should be selected according to the temperature, chemical properties and other factors of the transported liquid. For example, if the high temperature liquid contains harmful substances such as fluoride ion and chloride ion, PFA or PTFE and other relevant materials need to be selected for treatment of pump body parts, mechanical seals and bearing rings to ensure the safety of the equipment.

In conclusion, IMO screw pump needs to pay special attention to the above aspects in the process of delivering high-temperature liquid to ensure its normal operation and safety. Of course, in specific use, Viking It is also necessary to respond flexibly according to the situation and solve problems in time to ensure the stability and production efficiency of the equipment.
