The SIHI liquid ring vacuum pumps LEM are single-stage ones.
SIHI LEM系列液环式真空泵是单级泵。

NOTE注意事项
During operation the pump must continuously be supplied with service liquid, normally water, in order to eliminate the heat resulting from the gas compression and to replenish the liquid ring, because part of the liquid is leaving the pump together with the gas. This liquid can be separated from the gas in a liquid separator (see catalogue part accessories).It is possible to reuse the service liquid. The pumps are equipped with a device by which the contaminated service liquid can continuously be drained during operation (dirt drain), if necessary.
泵运转期间需连续不断地补充工作液(通常为水),以带走气体压缩而产生的热量和补充部分随气体排出的工作液。此部分工作液可在汽液分离器中与气体分开(请见样本附件部分),以重新利用。
泵可按需要配备汽液分离器,以保证在运转条件下连续地排放被污染的工作液。
The direction of rotation is clockwise, when looking from the drive on the pump.
从泵的驱动端看,泵的旋转方向为顺时针。
