Embodiment Construction
[0022] like Figure 1-3 As shown, a rotary jet pump includes a bearing housing 1, a main shaft 2 and a rotor chamber 4. A pump body 3 is installed behind the bearing housing 1, and a main shaft 2 runs through the middle of the inner side. The main shaft 2 is rotationally connected with the bearing housing 1 through a bearing group. One end of the main shaft is connected to the motor by a coupling, and the other end is connected to the rotor cavity 4 by a flange. The pump body 3 and the bearing box 1 are connected by bolts and precisely positioned by the seam to form a whole. Its feet are connected to the bearing box 1 The feet are adjusted to ensure the installation level of the pump. The rotor chamber 4 is arranged in the inner middle part of the pump body 3 and is fixedly connected with the main shaft 2. Its outer diameter is smaller than the inner diameter of the pump body 3, and the inner middle part of the rotor chamber 4 is equipped with a collecting pipe 5, and the righ...
