Working temperature and pressure of high-temperature melt pump
The working temperature and pressure of a high-temperature melt pump mainly depend on its design and materials. The following is general information about the working temperature and pressure of high-temperature melt pumps:
Working temperature: The working temperature of the high-temperature melt pump can reach 510 degrees Celsius (950 degrees Fahrenheit), which is sufficient to meet the transportation requirements of most polymer melts. However, there are also models with a maximum operating temperature limit of 400 degrees Celsius (750 degrees Fahrenheit). In special circumstances, high-temperature melt pumps can even operate at higher temperatures, but their performance and service life may be affected.
Working pressure: The working pressure of a high-temperature melt pump is usually represented by inlet pressure, outlet pressure, and pressure difference. The inlet pressure of a regular high-temperature melt pump is usually less than 10MPa, the outlet pressure is less than 35MPa, and the pressure difference can reach 25MPa. For melt pumps made of high-pressure materials, their outlet pressure can even reach 50MPa or 70MPa. These parameters can be selected and adjusted according to specific application requirements.
It should be noted that the working temperature and pressure of the high-temperature melt pump are interrelated. Higher temperatures may cause an increase in the pressure of the melt, while higher pressures may have an impact on the performance and lifespan of the pump. Therefore, when selecting and using high-temperature melt pumps, it is necessary to comprehensively consider specific process requirements and material characteristics.
In addition, to ensure the stable operation of the high-temperature melt pump and extend its service life, regular maintenance and upkeep are required. For example, cleaning the residue inside the pump body, checking the wear of bearings and seals, replacing lubricating oil, etc. These measures can effectively reduce the failure rate of pumps and improve their work efficiency. In summary, the working temperature and pressure of high-temperature melt pumps are important indicators of their performance, and their selection and use need to be comprehensively considered based on specific circumstances.
