摘要
在聚酰胺弹性体熔体输送过程中,熔体输送泵发生电流逐渐增大,直至超电流跳停的情况,影响生产的稳定运行。熔体输送泵由齿轮泵更换为双转子泵后,双转子泵运行电流平稳,无振动等异常情况,能满足熔体输送的要求。但是双转子泵的输送压力较低,不适用于压力较高场合。
In the process of polyamide elastomer melt transfer,the current of melt transfer pump increases gradually until the overcurrent trip,which affects the stable operation of production.When the melt pump is replaced by the double rotor pump,the current of the double rotor pump is steady and no vibration,which can meet the requirement of melt transportation.However,the double-rotor pump transport pressure is low,not suitable for higher pressure occasions.
