Description
Technical Field
The utility model relates to a drainage device for motor test.
Background
At present, the ventilation cooling of the motor with large capacity and high performance basically depends on a cooler. The motor using the water cooler needs to be cooled by water during the assembly test.
Usually, a water outlet pipeline of cooling water of the test station is connected with a water inlet flange of the cooler through a connecting water pipe, and a water outlet flange of the cooler is connected with a water return pipe on the test pit through the connecting water pipe for water drainage. After the motor is tested, the valve of the water outlet pipe on the pit is closed, residual water in the cooler and the connecting water pipe cannot be drained due to anhydrous pressure, and the residual water in the connecting water pipe and the cooler can be drained on the test pit to influence field management when the connecting water pipe and the cooler are dismounted, and even enters the motor to influence the quality of the motor. If the cooler with the residual water is packed and sent to a user in winter, the residual water is frozen when the motor is not installed and operated, and a water tank and a pipe in the cooler are frozen due to expansion with heat and contraction with cold.

The utility model aims at overcoming the not enough of prior art, provide a drainage device for motor test, its simple structure, convenient to use can be with the surplus water drain in outlet pipe and the cooler water tank.
The technical scheme for realizing the purpose is as follows: the utility model provides a drainage device for motor test, is including the water cooler that has into water flange and play water flange, the outlet pipe way and the return water pipeline that are equipped with the outlet valve, the water cooler is installed the upper end of motor, the return water pipeline pass through a return pipe with the play water flange joint of water cooler, the outlet pipe way pass through a outlet pipe with the flange joint that intakes of water cooler. The water outlet pipeline is connected with the water outlet pipe through a double-flange joint, the double-flange joint comprises a cylinder body and flanges connected to two ends of the cylinder body, an air pipe provided with an air valve is connected to the wall of the cylinder body, and the air pipe is communicated with external compressed air.
The above drainage device for the motor test, wherein the water return pipe and the water outlet pipe are both stainless steel corrugated pipes.
The above drainage device for motor test, wherein the motor and the water cooler are installed at the upper end of the test pit, and the water return pipeline and the water outlet pipeline are installed on a test pit and located beside the motor.
The utility model discloses a technical scheme for experimental drainage device of motor, simple structure, convenient to use can be with the surplus water drainage in outlet pipe and the cooler water tank. The device does not need to be modified on a test station, so that the production and the occupied production fund are not influenced.
Drawings
Fig. 1 is a schematic structural diagram of a drainage device for a motor test according to the present invention;
fig. 2 is a cross-sectional view of the double-flange joint of the drainage device for motor test of the present invention.
Detailed Description
In order to better understand the technical solution of the present invention, the following detailed description is made by specific embodiments with reference to the accompanying drawings:
referring to fig. 1 and 2, the water draining device for motor test of the present invention includes a water cooler 2, a water outlet pipe 3 with a water outlet valve 30, a water return pipe 4, a double-flange joint 5 and an air pipe 6. Wherein,
the motor 1 is arranged at the upper end of the test pit 10;
the water cooler 2 is arranged at the upper end of the motor 1, and the water cooler 2 is provided with a water inlet flange 21 and a water outlet flange 22;
the water return pipeline 4 is connected with the water outlet flange 22 of the water cooler 2 through a water return pipe 41; the water return pipe 41 is a stainless steel corrugated pipe;
the water outlet pipeline 3 is connected with a water inlet flange 21 of the water cooler 2 through a water outlet pipe 31; the water outlet pipe 31 is also a stainless steel corrugated pipe;
the water return pipeline 4 and the water outlet pipeline 3 are arranged on a test pit 10 and are positioned beside the motor 1;
the double-flange joint 5 comprises a cylinder body 50 and flanges 51 and 52 connected to two ends of the cylinder body; one flange 51 of the double-flange joint 5 is connected with a flange on the water outlet pipeline 3, and the other flange 52 of the double-flange joint 5 is connected with a flange on the water outlet pipe 31;
the air pipe 6 is connected to the wall of the cylinder 50 of the flange joint 5 and is communicated with the external compressed air, and an air valve 60 is arranged on the air pipe 6.
The utility model discloses a theory of operation for experimental drainage device of motor is:
when the motor 1 is in test, the air valve 60 on the air pipe 6 is closed, the water outlet valve 30 on the water outlet pipeline 3 is opened, and cooling water returns to the water return pipe 41 through the water cooler 2. After the motor 1 is tested, the water outlet valve 30 on the water outlet pipeline 3 is closed, residual water in the water outlet pipe 31 and the water cooler 2 is left in the water outlet pipe due to no pressure, then the air valve 60 on the air pipe 6 is opened, compressed air with six atmospheric pressures presses the water in the water outlet pipe 31 and the water tank of the cooler 2 into the water return pipeline 4, then the water outlet pipe 31 and the water return pipe 41 are disassembled, water is prevented from being discharged on a test bench, and finally the water cooler 2 is disassembled and then is boxed and transported to a user, so that the water tank is prevented from being frozen due to freezing of the residual water in the water cooler 2 in winter.
It will be appreciated by those skilled in the art that the above embodiments are only for illustrating the present invention and are not to be used as limitations of the present invention, and that changes and modifications to the above described embodiments will fall within the scope of the claims of the present invention as long as they are within the spirit and scope of the present invention.
