Summary of the invention
It is an object of the invention to provide a kind of water-cooled machine condensation water controller, this condensation water controller overcomes the deficiencies in the prior art, simple in construction, cost is low, effectively prevent the defect that water-cooled machine condensed water when not working or quit work stockpiles, ensure that the normal operation of water-cooled machine, extend the service life of motor, improve the safety and reliability of motor.
For reaching above-mentioned purpose, the technical solution adopted for the present invention to solve the technical problems is: a kind of water-cooled machine condensation water controller, it is characterized in that: on the end cap of motor lower portion, be provided with annular collecting vat, in the minimum point of annular collecting vat or be provided with the osculum downward no less than two apertures close to lowest point place, water inlet on motor housing and be respectively equipped with the valve controlling cooling water turnover on outlet, is provided with the filter meeting motor protection class requirement on osculum.
In technique scheme, one water-cooled machine of the present invention condensation water controller has following Advantageous Effects: first, one water-cooled machine of the present invention condensation water controller, and collection, discharge structure are simple, and control method is novel effectively；Second, the present invention is provided with annular collecting vat and osculum, water-cooled machine can be effectively prevent when not working or quit work, the condensed water that sub-cooled causes condenses and stockpiles, guarantee that the condensed water being likely to occur flow to annular collecting vat under gravity, and discharged by osculum, it is prevented that motor internal is owing to accumulating condensed water generation corrosion, insulating motor coil is caused to reduce, thus ensure that motor normal operation；3rd, osculum is provided with filter, can effectively discharge motor internal condensed water and prevent water, dirt etc. from entering motor, meet motor protection class requirement；4th, extend motor service life, improve motor safety and reliability.
