3、网Suction by means of a water jet pump水喷射泵产生真空具有一定压力的工作介质水，通过喷嘴向吸入室高速喷出，将水的压力能变为动能，形成高速射流；吸入室中的气体被高速射流强制携带与之混合，形成气液混合流，进入扩压器，从而使吸入室压力降低，形成真空，在扩压器的扩张段内，混合射流的动能转变为压力能，速度降低压力升高，气体被进一步压缩，与水一起排出泵外，在水箱中气水分离，气体释放入大气，水由水泵循环再利用，周而复始达到抽真空的目的。单级水喷射泵的喷嘴可以是由一个渐缩喷嘴构成的单喷嘴结构，也可以是在一个孔板上开设多个孔口的多喷嘴结构。柱塞泵提供高压水，清洗与产生真空?C

35、泵会有一定范围的脉冲，24（大大低于理论的大大低于理论的大大低于理论的大大低于理论的23，因为泵带有很高的阻尼系统因为泵带有很高的阻尼系统因为泵带有很高的阻尼系统因为泵带有很高的阻尼系统）的范围是完全正常的的范围是完全正常的的范围是完全正常的的范围是完全正常的。AMB Training|35Pump Reasons for Pulsation泵原因造成的脉冲泵原因造成的脉冲泵原因造成的脉冲泵原因造成的脉冲Dirt in Valves 阀内杂质阀内杂质阀内杂质阀内杂质If there is dirt in the valves,they cant close properly anymore.T
36、his leads to higher revolutions per minute and pulsation.If a new pump already shows pulsation when switching it on for the first time,dirt in the valves is a likely reason.如果泵单向阀有杂物，无法再关严，会导致泵更快的转速和更高的脉冲。特别是一个新泵在刚开机时就显示脉冲过高，那泵阀内有杂物应该是其原因。To flush out the dirt of the pump,open the blind plug at the
