采用本发明的催化剂的预处理方法使得催化剂进料泵出口压力明显偏低,催化剂进料稳定,无堵塞。
The catalyst pretreatment method ensures that the outlet pressure of the catalyst feed pump is remarkably lower, and catalyst feed is stable without blocking.
试验结果表明,改变泵出口管线结构,使泵出口压力在一定范围内工作时,流量变化大,而且泵效率较高,可以作为泵调整参数的一种手段;
The test results have proved that the flow rate widely varied and the pump efficiency is high when the pump outlet line structure was altered and the outlet pressure was controlled in a special limit.
由于变频器的使用,使泵转速下降,出口压力降低,减少了机械磨损,降低了维修工作量,延长了设备的使用寿命。
Because of the use of frequency converter, so that pump speed decreased, exports to reduce stress, a reduction of mechanical wear, reducing maintenance workload, extended equipment life.
