The main parameters of high-temperature melt pumps include, but are not limited to, the following aspects:
1. Displacement: the displacement of high temperature melt pumps is usually “cc” as a unit, indicating the volume of melt that can be transported by the pump per revolution. Displacement range from 0.1cc to 12000cc, specific selection needs to be determined according to the actual production requirements.
2. Pressure: The working pressure of high temperature melt pump is an important parameter, including suction pressure and output pressure. Suction pressure range is usually in the vacuum (-0.05 ~ -0.08MPa) to 30MPa between, while the output pressure can reach 0 ~ 40MPa. different models and specifications of the melt pump, its pressure parameters will be different.
3. Temperature: The working temperature of high temperature melt pump is also a key parameter. Generally speaking, the working temperature of melt pumps does not exceed 400℃, but some specially designed pumps may have higher temperature resistance. At the same time, the cleaning temperature may also be higher than the operating temperature, but generally does not exceed 450 ℃.
4. Viscosity: High temperature melt pumps have a wide range of viscosity applications, and can usually handle melts in the range of 1 to 40,000 Pa-s (or 1,000 to 4,000,000 cP). Different viscosity of the melt on the pump performance and selection have a certain impact.
5. Material: high temperature melt pump material selection is also critical, the pump body, gears, bearings and other parts of the material needs to be based on the characteristics of the transported melt and the working environment to determine. Common materials include nitrided steel, stainless steel, alloy steel and so on.
6. Driving mode: high temperature melt pump usually adopts the driving mode of motor + reducer + universal coupling, this driving mode has the advantages of compact structure and smooth operation.
7. Flow adjustment: high-temperature melt pump flow can be realized by adjusting the pump speed, frequency conversion speed control is a commonly used flow adjustment method, which can achieve nearly linear flow output.
In addition, high-temperature melt pumps also involves heating methods (such as electric heating or thermal media heating), sealing methods (such as packing seal or screw seal) and other parameters. In the selection of high-temperature melt pumps, you need to consider these parameters and the actual production requirements to ensure that the selected pump model can meet the production requirements and have good performance.
