深井泵与渣浆泵如何匹配  

深井泵如图5-44所示。由于受深井管径大小的限制，其吐出室为导流壳，故径向减小，轴向加长，以满足工况要求，其长度从几十米到一百多米，有一种吊泵甚至长几百米。深井泵由若干根轴和连接管组成，连接管与连接管或壳与壳连接有螺纹(见图5-44右图)和法兰连接(见图5-47) 两种，而轴与轴连接有螺纹连接(见图5-44)或卡环套连接(见图5-47)， 统称轴联轴器。螺纹连接用于小泵。深井泵轴向力及泵自重均由电动机来承受。

How to match deep well pump with slurry pump

The deep well pump is shown in Fig. 5-44. Due to the limitation of the diameter of the deep well, the discharge chamber is a diversion shell, so it is reduced in the radial direction and lengthened in the axial direction to meet the requirements of the working condition. Its length is from tens of meters to more than 100 meters, and one kind of hanging pump is even several hundred meters long. The deep well pump is composed of several shafts and connecting pipes. The connecting pipes and connecting pipes or shell and shell are connected by threads (see figure 5-44, right) and flange (see figure 5-47). The shafts and shafts are connected by threads (see figure 5-44) or snap ring sleeves (see figure 5-47), collectively referred to as shaft couplings. Threaded connections are used for small pumps. The axial force and the dead weight of the deep well pump are borne by the motor.
