Abstract
A kind of deep-well pump motor lower bearing protection device that the present invention provides; including 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 radially connected place 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.Owing to the present invention arranges waterproof cover at the gap of bearing end cover and between centers, the gap of water inlet is cut off, the passage do not entered, so the present invention will not cause bearing water inlet and motor damage because packing of long duration lost efficacy, extend the service life of motor, improve the reliability of motor.
Description
Technical field
The invention belongs to submersible motor field, particularly relate to a kind of deep-well pump motor lower bearing protection device.
Background technology
Hollow shaft motor is to drive deep well pump groundwater abstraction, and motor is installed above on ground, passes through motor
The power transmission shaft of rotor shaft hatch is connected with the drive flange of motor, drives pumping for water pump, and water pump seat is joined with pump shaft
Should there is packing_seal at conjunction, but packing is of long duration can lose efficacy leak (as shown in Figure 2), due to water
There is pressure time length can throw in lower bearing, damage burn-out of bearing motor.How to avoid because packing lost efficacy
Leak and cause lower bearing to damage motor damage so that lower bearing the most also enters and do not anhydrates, become
Problem for those skilled in the art's research.
Summary of the invention
First the problem to be solved in the present invention is to provide the high deep-well pump motor lower bearing of a kind of reliability and protects
Protection unit.
For solving the problems referred to above, the technical solution used in the present invention: a kind of deep-well pump motor lower bearing protection
Device, including waterproof cover, described waterproof cover is arranged at the outside of motor lower bearing enclosing cover, and described waterproof
Lid blocks the gap of motor lower bearing enclosing cover and the radially connected place of lower bearing, and 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, the boss of described waterproof cover
Outside be fixed to outside described lower bearing cover.
Described waterproof cover is circular, a diameter of described lower bearing enclosing cover external diameter of described circular waterproof cover
1/2 to 2/3.
Described waterproof cover is fixed to outside described lower bearing cover by screw with described lower bearing enclosing cover.
The present invention has the advantage that with good effect: 1. owing to the present invention is at the seam of bearing end cover Yu between centers
Waterproof cover is set at gap, the gap of water inlet is cut off, the passage do not entered, so the present invention will not be because of
Cause bearing water inlet for packing of long duration lost efficacy and motor damage, extend the service life of motor, carry
The reliability of high motor；2. waterproof cover is circular, and 1/2 to 2/3 that external diameter is lower bearing enclosing cover external diameter,
Adapt to while bearing profile, save material, and can ensure that and can shelter from bearing and bearing end cover footpath
To the gap of junction, improve reliability；3. waterproof cover is threadeded with bearing end cover, facilitates installation to tear open
Unload and safeguard.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the structural representation of prior art of the present invention；
Fig. 3 is the structural representation of waterproof cover of the present invention；
Fig. 4 is the profile of Fig. 3 of the present invention.
In figure: 1. lower bearing, 2. lower bearing enclosing cover, 3. waterproof cover.
Detailed description of the invention
The most with reference to the accompanying drawings the present invention is carried out explanation in greater detail, as shown in Fig. 1,3,4, a kind of deep-well
Pump motor lower bearing 1 water-tight device, including waterproof cover 3, described waterproof cover 3 is arranged at motor lower bearing
The outside of enclosing cover 2, and described waterproof cover 3 to block motor lower bearing enclosing cover 2 radially connected with lower bearing 1
The gap at place, the middle part of described waterproof cover 3 has the round boss of hollow, and described boss is arranged at lower axle
Hold in the central shaft hole of 1, outside the boss of described waterproof cover 3, be fixed to described lower bearing enclosing cover
On 2.
Described waterproof cover 3 is circular, outside a diameter of described lower bearing enclosing cover 2 of described circular waterproof cover 3
1/2 to the 2/3 of footpath.
Described waterproof cover 3 is fixed on described lower bearing enclosing cover 2 by screw with described lower bearing enclosing cover 2.
3 fixing holes are had on waterproof cover 3, as it is shown on figure 3, with screw through 3 fixing holes by waterproof cover
It is fixed on lower bearing enclosing cover 2.
Above embodiments of the invention are described in detail, but described content has been only the preferable of the present invention
Embodiment, it is impossible to be considered the practical range for limiting the present invention.All according to the scope of the invention made equal
Deng change and improvement etc., within all should still belonging to this patent covering scope.
