What are the requirements of High Pressure Online Circulation Pump for the medium it conveys?

Publish Time: 2024-10-11
1. Physical property requirements of the medium

First, the viscosity of the medium has an important influence on the operation of the High Pressure Online Circulation Pump. Generally speaking, the circulation pump is more suitable for conveying low-viscosity media, such as clean water, light oil, etc. If the viscosity of the medium is too high, it will increase the running resistance of the pump, reduce the flow rate and efficiency, and may even cause the pump to fail to start normally. In addition, the temperature of the medium also needs to be within a certain range. Too high a temperature may damage the seals and internal components of the pump, affecting the service life of the pump; too low a temperature may cause the medium to solidify or become too viscous, which is also not conducive to the normal operation of the pump.

2. Chemical property requirements

For the High Pressure Online Circulation Pump, the chemical properties of the medium are also an important factor to consider. If the conveyed medium is corrosive, it is necessary to select a pump material with corrosion resistance, such as stainless steel, engineering plastics, etc. Otherwise, the medium will corrode the internal structure of the pump, causing leakage, damage and other problems. At the same time, the medium cannot contain too many impurity particles, because these particles may wear the pump's impeller, seals and other components, reducing the performance and life of the pump. If the medium inevitably contains impurities, a filter should be installed at the inlet of the pump to protect the normal operation of the pump.

3. Cleanliness requirements

The transported medium should have a certain degree of cleanliness. If the medium contains a large amount of dirt, sediment or other contaminants, it may block the flow channel of the pump and affect the flow and pressure of the pump. In some applications with high cleanliness requirements, such as chemical and pharmaceutical industries, the medium may need to be pretreated to ensure that it meets the use requirements of the pump. In addition, the medium cannot contain gas or steam, because these gases will form cavitation in the pump, damage the impeller and seals of the pump, and reduce the performance of the pump.

4. Stability requirements

The medium should maintain relatively stable properties during the transportation process. It should not be volatile, easy to decompose, easy to polymerize, etc., otherwise it may affect the normal operation of the pump. For example, if the medium undergoes a polymerization reaction in the pump, it may block the flow channel of the pump and cause the pump to fail to work properly. At the same time, the chemical properties of the medium cannot change drastically during the transportation process to avoid corrosion or damage to the pump material. In summary, High Pressure Online Circulation Pump has strict requirements on the medium to be transported. When selecting and using a circulation pump, the physical and chemical properties of the medium as well as factors such as cleanliness and stability must be fully considered to ensure the normal operation and service life of the pump.
