Thread Content

1"작동 시 작은 泵常回流,大泵不回流"에 대해 관련 표준이나 원인을 찾지 못했습니다. 이 부분에 대해 해우해 주시면 감사하겠습니다!

2"이것은 작고 큰 泵的操作工况确定,总的来说,不管小泵还是大泵都不能长期憋压。

"그렇다면 작고 큰 泵正常工作时;小泵不回流,大泵常回流是否合理?根据是什么?谢谢!

"이 말은 어느 정도 맞습니다. 보통 작은 泵的最小回流通常采用节流孔板,一直有流量;而大的 泵的最小回流通常采用流量调节阀,泵正常运转时,调节阀是关闭的的,所以没有流量.

"이것은 泵的最小连续运行稳定流量、热控最小流量有关

"작은 泵本身功率小,常回流可以防止憋压同时又不增加多少能耗 大泵功率大所以常回流说明设计不合理常回流需要耗很多电

"보통 泵压力与流量有个适宜范围运行而泵越小这个范围越小而小泵一般都选型都偏大较多无回流的话流量低的时候泵压力较高而小泵耐压能力差结果你懂的。

"보통 离心泵≥30%额定流量就不需要开回流。回流是避免憋泵造成介质高温气蚀造成设备损坏
