Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example (b): as shown in fig. 1: a mining pump structure, first the paired angular contact ball bearings 20 are installed on the spindle 14 in the bearing body 15 inner sleeve, locked with two round nuts 21, and compressed with the second bearing gland 22 and sealed with the seal retainer ring 17; and then the paired deep groove ball bearings 18 are sleeved on the other side of the rotating shaft 14 in the bearing body 15, and are tightly pressed by the first bearing gland 16 and then sealed by the sealing retainer ring 17, the upper part of the bearing body 15 is provided with the second air release plug 19 to form the bearing part 15, and then the bearing part 15 is placed on the support 11.

Then, the sealing gland 10, the pressing sleeve 9, the leather cup seal 8, the rear gland 6 and the rear guard plate 5 are sleeved on the rotating shaft 14 in sequence according to the figure 1, the key 13 and the impeller 2 are installed, and the impeller 2 is locked on the rotating shaft 14 through the impeller nut 7.
