Abstract
The utility model relates to a submersible motor with an upper bearing cooling mechanism, which comprises a stator, a rotor, an upper bearing, an upper end cap and a connection box. The upper bearing is positioned on a rotor shaft at the position of the upper end cap, the upper end cap is a double-layer cap consisting of an upper cap and a lower cap, the lower end of the connection box is connected with the lower cap of the upper end cap, an annular water guide plate is arranged between the upper cap and the lower cap of the upper end cap, water inlets are evenly distributed on the side wall of the connection box on the lower portion of the water guide plate, the outer side of the connection box corresponding to the water inlets is provided with an air guide sleeve, and water outlets are evenly distributed on the side wall of the connection box on the upper portion of the water guide plate. The outer wall of the upper bearing is cooled by the aid of flowing water so that the shortcoming of over-high temperature rise of an original upper bearing is successfully overcome, and the bearing temperature after improvement is reduced to below 60 DEG C so that potential safety hazards during running of the submersible motor is completely avoided.
Description
Technical field
The utility model belongs to technical field of motors, is specifically related to a kind of submersible motor.
Background technology
Along with developing rapidly of submersible pump maximization in recent years, the large-scale electric underwater pump of band planetary reducer is also succeeded, is used widely.The too high problem of temperature rise of upper bearing (metal) has also appearred in the submersible pump of this type in application process.Routinely, upper bearing (metal) is non-shaft extension force side, particularly when the vertical operating condition of submersible pump, bear any axial force hardly, but result of the test shows, the upper bearing (metal) temperature rise is obviously higher than what envision, and it is undesirable that promptly upper bearing (metal) may bear sizable axial force and radial load or heat radiation situation, to such an extent as to the upper bearing (metal) temperature rise is higher.The upper bearing (metal) temperature of this kind submersible pump reaches eighties degree after tested, and is obviously more higher than the bearing temperature rise of anticipation.This brings very big potential safety hazard for the safe operation of this type of submersible pump.The upper bearing (metal) of submersible motor is positioned at the upper end cover position, and upper end cover top is provided with the junction box, and the bottom is a support, and mainly by the work of the external world between upper end cover stagnant water, cooling effect is not obvious in the cooling of upper bearing (metal).
Summary of the invention
For the upper bearing (metal) that solves submersible motor moves the security hidden trouble that brings under higher temperature, the utility model provides a kind of submersible motor with upper bearing (metal) cooling mechanism.
Concrete Technological improvement plan is as follows:
Submersible motor with upper bearing (metal) cooling mechanism, comprise stator, rotor, upper bearing (metal), upper end cover, junction box, upper bearing (metal) is positioned on the armature spindle at upper end cover place, the Double layer lid that upper end cover is made up of upper strata lid and lower floor's lid, its upper strata lid diameter covers diameter less than lower floor, and junction box's lower end is connecting lower floor's lid of upper end cover; Be provided with the weather board of ring-type between the upper strata lid of described upper end cover and the lower floor's lid, be laid with water inlet on junction box's sidewall of weather board bottom, the junction box outside corresponding with water inlet is provided with kuppe; Be laid with delivery port on junction box's sidewall on weather board top.
Be laid with eight water inlets on junction box's sidewall of described weather board bottom, be laid with eight delivery ports on junction box's sidewall on weather board top, described water inlet diameter is the 30-40 millimeter, and described delivery port diameter is the 30-40 millimeter.The moving water of the utility model utilization cools off the upper bearing (metal) outer wall, successfully solves the too high drawback of original upper bearing (metal) temperature rise, and the bearing temperature after the improvement is reduced to below 60 degree, has thoroughly solved the potential safety hazard that this submersible pump is in operation.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the partial enlarged drawing of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment:
Referring to Fig. 1 and Fig. 2, submersible motor with upper bearing (metal) cooling mechanism comprises stator 2, rotor 7, upper bearing (metal) 5, upper end cover 4, junction box 6, upper bearing (metal) 5 is positioned on the armature spindle at upper end cover 4 places, the Double layer lid that upper end cover 4 is made up of upper strata lid and lower floor's lid, its upper strata lid diameter covers diameter less than lower floor, and junction box 6 lower end is connecting lower floor's lid of upper end cover 4.Be installed with the weather board 3 of ring-type between the upper strata of upper end cover 4 lid and the lower floor's lid, uniformly on junction box's sidewall of weather board 3 bottoms offer eight water inlets 8, junction box 6 outsides corresponding with water inlet 8 are installed with kuppe 1; Uniformly on junction box's 6 sidewalls on weather board 3 tops offer eight delivery ports 9.Water inlet 8 diameters are 40 millimeters, and delivery port 9 diameters are 40 millimeters.
Operation principle: in submersible pump when work,, when the pumping current were flowed through upper end cover 4, a part of water entered the annulus of kuppe 1, entered zone between the upper strata lid of upper end cover 4 and the lower floor's lid through the water inlet 8 that is provided with on the kuppe 1 again.3 pairs of current that enter around here of weather board lead.So the direction of current direction delivery port 9 flows, the bearing outer wall of upper end cover 4 is cooled off, thereby upper bearing (metal) 5 is cooled off, reduce the temperature rise of upper bearing (metal) 5, improve the operational reliability of submersible pump.
