Press the "Start" button, the pump running, then open the suction valve of the pump.

按下水泵“开”按钮，泵即运转；然后打开泵的吸入阀。

How it works: the piston moves from left to right, form a negative pressure pump cylinder, then the suction tank fluid through the valve into the pump cylinder.

工作原理：活塞自左向右移动时，泵缸内形成负压，则贮槽内液体经吸入阀进入泵缸内。

Should be fully open before the start of suction and discharge pipe valves, non-closing valve started.

启动前应全开吸入和排出管路中的阀门，严禁闭阀启动。

In the alternating suction and discharge valve under the influence of pressure delivery and recycling to achieve the purpose of washing fluid.

在吸入和排出阀的交替作用下﹐实现压送与循环冲洗液的目的。

Project standard STPE-0101 page 43 requires that the suction piping up to suction block valve (including the valve) should be rated as discharge piping.

项目标准STPE - 0101第43项要求：直到吸入切断阀(包括阀)的吸入口管道应按排放管道定型？
