The device for preventing water from entering the motor by utilizing the positive pressure method comprises sealant, a first pipeline joint, a second pipeline and a second pipeline joint, wherein the sealant is arranged at the position of the motor where water easily enters, a threaded hole is formed in the bottom of the motor, the first pipeline joint is connected to the threaded hole, one end of the first pipeline is connected with the motor through the first pipeline joint, the other end of the first pipeline is connected to the second pipeline through the second pipeline joint, one end of the second pipeline is sealed, and compressed air is introduced into the other end of the second pipeline. The motor is internally positive-pressure, so that water mist can be effectively prevented from entering the motor through gaps. The air pipe adopts a PU air hose, and the joint adopts a PU hose quick joint, so that the installation is simple, and the sealing performance is good.
Description
Technical Field
The utility model relates to a more motor of various metallurgy and other installation environment water smoke.
Background
The motor is arranged in the environment with serious water mist, and particularly when the motor bears pressurized water impact, if the protection capability of the motor is not high, water is easily fed into the motor, and a winding is grounded until the motor is burnt. This device is through installing the drainage tube in the motor bottom, and the effectual inside water that will get into the motor is drawn forth, prevents that motor winding from taking place the ground connection and burning out the trouble.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a device that utilizes the malleation method to prevent that the motor is inside to intake to the above-mentioned problem.
The utility model aims at realizing like this, utilize the malleation method to prevent the inside device of intaking of motor, include, sealed glue, first pipeline, first pipe joint, second pipeline and second pipe joint, the position department of easily intaking of motor is provided with sealed glue, and threaded hole department has seted up threaded hole, and threaded hole department is connected with first pipe joint, and first pipeline one end is connected with the motor through first pipe joint, and the first pipeline other end is connected to the second pipeline through second pipe joint, and second pipeline one end is sealed, and the other end lets in compressed air.
Further, the internal pressure of the pipeline is 0.1-0.4 Mpa.
Furthermore, the first pipeline and the second pipeline are both air hoses.
The utility model has the advantages that: the motor is internally positive-pressure, so that water mist can be effectively prevented from entering the motor through gaps. The air pipe adopts a PU air hose, and the joint adopts a PU hose quick joint, so that the installation is simple, and the sealing performance is good.
Drawings
The present invention will be further described with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of the present invention.
Wherein: 1. the air compressor comprises a first motor, 2. a second motor, 3. a third motor, 4. a first pipeline, 5. a second pipeline and 6. compressed air.
Detailed Description
As shown in the figure, the bottoms of the first motor, the second motor and the third motor are connected with a first pipeline through pipeline joints, the three pipelines are connected to a second pipeline through pipeline joints, one end of the second pipeline is sealed, and compressed air is introduced into the other end of the second pipeline.
Wherein, first pipeline and second pipeline all adopt PU air hose, and pipe joint all adopts PU hose quick-operation joint.
In order to protect the motor and facilitate field installation, the device adopts the following technical scheme:
1. the sealing condition of the motor is checked, and the part which is easy to be water inlet is blocked by silicon rubber or sealant.
2. The bottom of the motor is provided with a threaded hole (which can be finished by a motor manufacturer when the motor is customized), and an air hose joint is installed.
3. The air hoses are butted with the motors one by one. The other ends of the hoses are connected together, so that all the motors form a closed space.
4. One section of the air hose is blocked, and the other end of the air hose is inserted into compressed air, so that positive pressure is formed inside the whole motor, and water mist and the like are prevented from entering the motor.
Utilize pneumatic hose to couple together the motor through motor bottom trompil, form an inclosed space, let in compressed air in the pneumatic hose, make the inside malleation that forms of motor, the effectual water smoke that prevents gets into inside the motor through the gap, guarantees the motor normal operating.
Wherein, the internal pressure of the pipeline is 0.1MPa-0.4MPa, and when the number of connected motors is less than or equal to 5, the internal pressure of the pipeline is 0.1 MPa. The pressure in the pipeline can be adjusted and tested according to the number of the actual motors, and the more the motors are, the larger the pressure value is, but the maximum pressure value cannot exceed 0.4 MPa.
A motor 387 is installed on a hot output roller way of a hot continuous rolling production line, side water spraying devices are installed on two sides of the roller way, a laminar cooling device is installed on the top of the roller way, water mist in the running environment of the motor is serious, part of the motors bear water flow impact for a long time, and the phenomenon of water inflow inside the motors often occurs. To on-the-spot and motor operation condition, strengthened the protection to the motor, installed the atmospheric pressure hose simultaneously in the motor bottom, inserted compressed air, made inside the whole motor abdominal cavity relative to the surrounding environment formation malleation, the effectual water smoke that prevents gets into inside the motor through the gap. The effect is good after the operation on site.
The above description is only for the specific embodiment of the present invention, but the structural features of the present invention are not limited thereto, and any person skilled in the art can make changes or modifications within the scope of the present invention.
