Abstract
A kind of deep-well pump motor lower bearing water-tight device that the utility model provides, comprise waterproof cover, described waterproof cover is arranged at the outside of motor lower bearing enclosing cover, and described waterproof cover blocks the gap of motor lower bearing enclosing cover and the radial junction of lower bearing, the middle part of described waterproof cover has the round boss of hollow, described boss is arranged in the central shaft hole of lower bearing, and being fixed to outside described lower bearing outside the boss of described waterproof cover covers.Because the utility model arranges waterproof cover at the gap place of bearing end cover and between centers, the gap of water inlet is cut off, the passage of not entering, so the utility model will cause bearing to intake and motor damage because packing of long duration lost efficacy, extend the useful life of motor, improve the reliability of motor.
Description
Technical field
The utility model belongs to submersible motor field, particularly relates to a kind of deep-well pump motor lower bearing water-tight device.
Background technology
Hollow shaft motor drives deep well pump groundwater abstraction, motor is installed more than ground, be connected with the drive flange of motor by the power transmission shaft of rotor axis hole, drive pumping for water pump, should there be packing_seal water pump seat and pump shaft cooperation place, but packing is of long duration can lose efficacy and leak (as shown in Figure 2), can throw in lower bearing because water has had pressure time to grow, damage burn-out of bearing motor.How to avoid causing lower bearing to damage motor damage because packing lost efficacy to leak, lower bearing is under any circumstance also entered and does not anhydrate, become the problem of those skilled in the art's research.
Utility model content
First problem to be solved in the utility model is to provide the high deep-well pump motor lower bearing water-tight device of a kind of reliability.
For solving the problem, the technical solution adopted in the utility model: a kind of deep-well pump motor lower bearing water-tight device, comprise waterproof cover, described waterproof cover is arranged at the outside of motor lower bearing enclosing cover, and described waterproof cover blocks the gap of motor lower bearing enclosing cover and the radial junction of lower bearing, the middle part of described waterproof cover has the round boss of hollow, and described boss is arranged in the central shaft hole of lower bearing, and being fixed to outside described lower bearing outside the boss of described waterproof cover covers.
Described waterproof cover is circular, and the diameter of described circular waterproof cover is 1/2 to 2/3 of described lower bearing enclosing cover external diameter.
Described waterproof cover and described lower bearing enclosing cover are fixed to outside described lower bearing by screw and cover.
The advantage that the utility model has and good effect are: 1. because the utility model arranges waterproof cover at the gap place of bearing end cover and between centers, the gap of water inlet is cut off, the passage of not entering, so the utility model will cause bearing to intake and motor damage because packing of long duration lost efficacy, extend the useful life of motor, improve the reliability of motor; 2. waterproof cover is circular, and external diameter is 1/2 to 2/3 of lower bearing enclosing cover external diameter, while adapting to bearing profile, saves material, and can guarantee the gap sheltering from bearing and the radial junction of bearing end cover, improves reliability; 3. waterproof cover is threaded with bearing end cover, facilitates installing/dismounting and maintenance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model prior art;
Fig. 3 is the structural representation of the utility model waterproof cover;
Fig. 4 is the profile of the utility model Fig. 3.
In figure: 1. lower bearing, 2. lower bearing enclosing cover, 3. waterproof cover.
Embodiment
Now with reference to the accompanying drawings comparatively detailed description is carried out to the utility model, as shown in Fig. 1,3,4, a kind of deep-well pump motor lower bearing 1 water-tight device, comprise waterproof cover 3, described waterproof cover 3 is arranged at the outside of motor lower bearing enclosing cover 2, and described waterproof cover 3 blocks the gap of motor lower bearing enclosing cover 2 and the radial junction of lower bearing 1, the middle part of described waterproof cover 3 has the round boss of hollow, described boss is arranged in the central shaft hole of lower bearing 1, being fixed on described lower bearing enclosing cover 2 outside the boss of described waterproof cover 3.
Described waterproof cover 3 is circular, and the diameter of described circular waterproof cover 3 is 1/2 to 2/3 of described lower bearing enclosing cover 2 external diameter.
Described waterproof cover 3 is fixed on described lower bearing enclosing cover 2 by screw with described lower bearing enclosing cover 2.Waterproof cover 3 has 3 fixing holes, as shown in Figure 3, through 3 fixing holes, waterproof cover is fixed on lower bearing enclosing cover 2 with screw.
Above embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model scope change and improve, and all should still belong within this patent covering scope.
