Although the melt pump for PPS plastic granule raw materials has extensive application value in the plastics processing industry, it also exhibits some drawbacks, primarily including the following aspects:
Sensitivity to Melt Temperature:
PPS plastics melt at high temperatures, and the melt pump operates in such high-temperature environments. Excessively high or fluctuating melt temperatures may affect the performance and service life of the melt pump.
High temperatures may accelerate the aging or wear of components such as seals and bearings in the melt pump, thereby impacting the pump's stability and reliability.
Wear and Maintenance:
During operation, the melt pump experiences wear on components like gears and bearings due to the melt. This wear is inevitable, but long-term wear can lead to performance degradation and even the need for component replacement.
The maintenance cost of the melt pump is relatively high, requiring regular inspections and replacements of worn components to ensure normal operation.
Adaptability to Melt Viscosity:
PPS plastics have a relatively high viscosity, posing certain requirements on the conveying capacity of the melt pump. Excessively high melt viscosity may increase the conveying difficulty and energy consumption of the melt pump.
Simultaneously, changes in melt viscosity can also affect the conveying stability and accuracy of the melt pump.
Requirements for Installation and Maintenance Personnel:
Installing and maintaining a melt pump requires specific professional knowledge and skills. Improper installation or untimely maintenance may lead to performance degradation or failures in the pump.
Therefore, professional technicians are required for the installation, commissioning, and maintenance of the melt pump.
Investment Cost:
As a type of plastics processing equipment, the investment cost of the melt pump is relatively high. For small to medium-sized plastic granule production enterprises, this may be an economic factor to consider.
In summary, although the melt pump for PPS plastic granule raw materials has extensive application value, it also exhibits some drawbacks. When selecting and using it, comprehensive consideration should be given based on the actual needs and economic conditions of the enterprise to ensure that the melt pump can maximize its benefits. Additionally, regular maintenance and servicing of the melt pump are necessary to extend its service life and improve performance stability.
