Background
The air-air cooler is used as a main heat exchange component of the motor, is an important product for maintaining the operation of the motor, and directly influences the temperature rise, the power and the service life of the motor. The air-air cooler utilizes power to drive the impeller to rotate, the generated vortex continuously sucks air, and cold air is contacted with the hot pipeline and then transfers heat to cool hot substances in the pipeline. The cooling medium is external peripheral air, and due to the bottlenecks of the external diameter and the air volume of the single impeller assembled at the non-shaft-extension end of the large-scale motor cooler, the better requirement of the air inlet volume of the external air passage of the cooler can be met by the double impellers. However, the increase of the wind pressure caused by the air intake inside the double impellers can cause the lubricating oil on the bearing of the large motor to be easily sucked away, and particularly, under the condition that a cooler with larger heat exchange power is used and the distance between the end cover of the cooler installed on site and the motor is limited, the phenomenon is more serious, so that the adverse effect is brought to the matching use of the motor and the cooler.

Detailed Description
The present invention will be further described with reference to the drawings and examples, but the present invention is not limited to the examples, and all similar structures and similar variations using the present invention shall fall within the scope of the present invention. The use of the directions of up, down, front, back, left or right in the present invention is only for the convenience and clarity of description, and is not a limitation to the technical solution of the present invention.
Example 1
As shown in fig. 1, fig. 2 and fig. 3, the inner side air inlet cover of a large motor cooler of the present invention includes an air collector air inlet barrel 1, the air collector air inlet barrel 1 includes a shell side plate 2 and an inner air collecting side plate 3, the shell side plate 2 and the inner air collecting side plate 3 are coaxially disposed, a gap is disposed between the edge of the shell side plate 2 and the edge of the inner air collecting side plate 3 along the circumferential direction, the gap forms a circle of air inlet 4, a screen 5 is disposed in the air inlet 4 along the circumferential direction, a first through hole 6 is disposed in the shell side plate 2 along the axial direction, a second through hole 7 is disposed in the inner air collecting side plate 3 along the axial direction, and the periphery of the inner air collecting side plate 3 is connected with a flange ring 8.
Further, still include bearing seal crown plate 9, be provided with axle mounting hole 10 and two above first mounting holes 11 in the bearing seal crown plate 9, first mounting hole 11 is along the circumferencial direction equipartition of bearing seal crown plate 9, be provided with the second mounting hole 12 that corresponds with first mounting hole 11 on the shell curb plate 2, the diameter of second mounting hole 12 is greater than first mounting hole 11, bearing seal crown plate 9 is connected with shell curb plate 2 through first mounting hole 11, second mounting hole 12, bolt 13, nut.
Because the axial air inlet can be reduced by reducing the clearance between the motor spindle and the wall of the shaft mounting hole 10 as much as possible, the diameter of the shaft mounting hole 10 only needs to be a little larger than that of the motor spindle, and therefore the oil absorption phenomenon is further reduced. If the motor spindle deviates from the axis of the first mounting hole 11 during mounting, the diameter of the second mounting hole 12 is larger than that of the first mounting hole 11, so that the bolt 13 can be loosened, the position of the shaft seal ring plate 9 can be adjusted, and the field mounting is convenient.
Furthermore, the air inlet cylinder 1 of the air collector is conical.
Further, the shell side plate 2 is provided with an inner concave part 15.
Furthermore, a reinforcing rib 16 is arranged between the shell side plate 2 and the inner wind collecting side plate 3.
Specifically, the mesh plate 5, the flange ring 8, the reinforcing ribs 16, and the like in this embodiment all adopt the known solutions in the prior art, which are known to those skilled in the art and will not be described herein again.
The working principle of the embodiment is as follows:
the utility model adopts annular air inlet, so that outside air can effectively enter from the air inlets 4 around the outer ring side of the shell, axial air inlet is reduced, and the oil absorption influence of axial air pressure on the bearing is avoided. The mesh plate 5 is used to filter impurities. The air inlet cylinder 1 of the inner conical air collector can more stably induce air, and the axial air pressure is greatly weakened, so that the phenomenon that the shaft end of a large motor is absorbed by oil can be effectively avoided compared with a conventional simple air inlet cover, and the stability of lubricating oil in a bearing of the large motor is enhanced.
The inner air inlet cover of the large motor cooler is convenient to process, low in manufacturing cost, convenient and fast to install, flexible to use, long in service life and basically free of consumable materials, axial air pressure generated by an inner air inlet of the large motor cooler is effectively weakened through air drainage of the air around the outer ring of the air inlet cover of the cooler, and the phenomenon that a motor bearing is absorbed by oil due to the axial air inlet pressure is avoided.
