【摘要】 对于小型储配站,因为流量小,可以选用价格上占优势的滑片泵。对于大型储配站,因为自动化水平较高,附属设施多,安全性要求更高,可以选用零泄漏的屏蔽泵或磁力泵。需注意的是,屏蔽泵效率较低,不允许长时间在小流量工况下运行,但其价格较低。磁力泵的工艺性能好,但价格稍高。更多还原

【Abstract】 Small scale LPG storage and filling station apt to vane pump, which is cheap and suitable for small flow. Because of the higher automation level, more ancillary facility and higher security requirements, large scale LPG storage and filling station need zero leakage pump, such as canned motor pump and magnetic pump. Canned motor pump have low efficiency, small flow is not permitting, but it is cheaper than magnetic pump. The technology of magnetic pump is most excellent.更多还原
