Abstract
The utility model relates to a submerged electric pump, in particular to a submerged electric pump with a bearing outer ring anti-shifting device. A motor is disposed on the upper portion of the submerged electric pump, a pump body is arranged on the lower portion of the submerged electric pump, bearings are evenly arranged on the upper portion and the lower portion of the motor, a lower bearing outer ring of the submerged electric pump is not higher than the depth of a lower bearing assembling hole, pressure plates symmetrically arranged on an annular boss on the periphery of the lower bearing outer ring are tightly positioned on the annular boss via a fastening piece, and the lower end surfaces of the pressure plates contact with at least one point arranged on the upper end surface of the lower bearing outer ring. The submerged electric pump has the advantages of adopting the simple and efficient lower bearing anti-shifting device, solving the problem of water pump quality caused by up and down movement of a lower bearing and prolonging the service life of a water pump.
Description
Technical field
The utility model relates to a kind of Submerged Motor Pumps, specifically refers to a kind of Submerged Motor Pumps with the anti-moving device of bearing outer ring.
Background technique
Submerged Motor Pumps since when assembling electric machine rotor axially misplace, water pump vane axially loaded area does not wait, water pump often stops aspect such as shutdown all can make water pump produce axial force, and this axial force is not same direction, so anti-reliably moving device will all will be arranged at the above-below direction of lower bearing.How existing Submerged Motor Pumps does not effectively control the upper and lower play in lower bearing outer ring, has influenced the Submerged Motor Pumps life-span greatly.
Existing Submerged Motor Pumps, most manufacturers only have anti-moving device downwards to bearing outer ring, and a part of manufacturer adopts traditional bearing gland that the outer ring is prevented.
Summary of the invention
The purpose of this utility model is according to above-mentioned the deficiencies in the prior art part, a kind of Submerged Motor Pumps with the anti-moving device of bearing outer ring is provided, revise the lower bearing pilot hole degree of depth, guarantee that the pilot hole degree of depth is less than bearing outer ring length, uniform two pressing plates on the pilot hole both sides, guarantee bearing outer ring play up and down, the quality and the life-span of improving Submerged Motor Pumps.
The purpose of this utility model realizes being finished by following technological scheme:
A kind of Submerged Motor Pumps with the anti-moving device of bearing outer ring, top is motor, the bottom is the pump housing, the motor upper and lower is provided with bearing, the lower bearing outer ring height of this Submerged Motor Pumps is not less than described lower bearing pilot hole hole depth, be symmetrically arranged with pressing plate on the annular boss on described lower bearing outer ring week edge, be fixed on described annular boss by fastening piece, described pressing plate lower end surface contacts more at least with upper-end surface, lower bearing outer ring.
Be symmetrically arranged with two pressing plates on above-mentioned annular boss, described fastening piece is a bolt, the pad of described pressing plate for matching with described bolt.
The utility model has the advantages that, adopt the anti-moving device of a kind of advantages of simplicity and high efficiency lower bearing, solved the water pump quality problems that cause because of the upper and lower play of lower bearing, prolong water pump working life.
Description of drawings
Fig. 1 is the utility model Submerged Motor Pumps structural representation;
Fig. 2 is the anti-moving device generalized section of bearing outer ring.
Embodiment
The utility model feature and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
Label 1-10 representative is upper bearing (metal) 1, motor 2, the anti-moving device 3 of bearing outer ring, lower bearing 4, the pump housing 5, lower bearing inner ring 6, lower bearing outer ring 7, hexagon head bolt 8, pressing plate/pad 9, annular boss 10 among the accompanying drawing 1-2.
How present embodiment does not effectively control the upper and lower play in lower bearing outer ring at existing Submerged Motor Pumps, has designed the anti-moving device of bearing outer ring at the lower bearing place, guarantees bearing outer ring play up and down.
Claims (3)
1. one kind has the anti-Submerged Motor Pumps that moves device of bearing outer ring, top is motor, the bottom is the pump housing, the motor upper and lower is provided with bearing, the lower bearing outer ring height that it is characterized in that this Submerged Motor Pumps is not less than described lower bearing pilot hole hole depth, be symmetrically arranged with pressing plate on the annular boss on described lower bearing outer ring week edge, described pressing plate is fixed on described annular boss by fastening piece, and the pressing plate lower end surface contacts more at least with upper-end surface, lower bearing outer ring.
2. as claim 1 described a kind of Submerged Motor Pumps, it is characterized in that on described annular boss, being symmetrically arranged with two pressing plates with the anti-moving device of bearing outer ring.
3. as claim 1 described a kind of Submerged Motor Pumps, it is characterized in that described fastening piece is a bolt, the pad of described pressing plate for matching with described bolt with the anti-moving device of bearing outer ring.
