Both pumps are in sanitary execution, fully made in stainless steel AISI 316l, and designed to guarantee water circulation even in the stand-by pump.
两台泵均执行卫生标准，全部由不锈钢aisi 316l制造，被设计用来保证备用泵内水循环平稳。
Both water inlet and outlet pipelines should be supported by a separate stand and not by the pump body.
进出水管路应另设支架支撑，不得籍泵本体支撑。
Stop the pump, close the column outlet and remove the packing reservoir. This is most easily done by first removing the column from the stand and then unscrewing the reservoir over a sink.
停止泵压，关闭柱的出口，去除填压用的贮液器。首先从试管架上卸下柱体，然后从槽上拧下贮液器，这样就很容易完成。
As for the existing benzene-spurting for the stand-by distillating pump since test running, we analyse it from the aspects of operation and design and raise the corresponding innovative approach.
