Embodiment Construction
[0010] The present invention will be further described below in conjunction with the accompanying drawings.
[0011] like figure 1 As shown in , a pump shaft bushing for a double suction pump includes a bushing body 1, the interior of the bushing body 1 is a cylindrical cavity structure, and an annular groove 2 is provided on the inner wall on the left side of the bushing body 1, On the outer side of the right end of the sleeve main body 1 is an arc-shaped structure 3 smoothly connected with the sleeve main body 1. The inner wall of the sleeve main body 1 corresponding to the arc-shaped structure 3 is provided with an annular step 4, and the annular step 4 and the impeller are arranged on the pump. The steps formed when the shaft is on the shaft match, and several through holes 5 are evenly arranged around the main body 1 of the sleeve.
[0012] Preferably, the through holes 5 are distributed in an array on the sleeve body 1 .
[0013] In practice, the annular groove 2 of th...
