Description
Technical field
The utility model relates to ventilator structure and air quantity control technique field, specifically is the controlled air quantity ventilation of mobile cantilever type unit.
Background technique
Temperature rise is the temperature difference of motor and environment, causes by the motor feels hot.Temperature rise is a design of electrical motor and an operating important indicator, indicates the degree of heat of motor, is in operation, and increases suddenly as electric machine temperature rise, illustrates that motor has fault, or the air channel is blocked or overload of power.In general, whenever be higher than 10 ℃ of temperature rise limits, electrical machinery life will reduce half.The temperature rise of motor not only has relation with the thermal source (various loss) and the method for operation of motor internal, also with motor surrounding environment heat dissipation capability relation is arranged.The temperature rise that reduces motor can strengthen the heat-transfer capability of motor internal and the heat dissipation potential on motor surface.It is self cooling that general middle and small motor all is equipped with fan; The motor of larger capacity adopts separate fan separately cooled type or pipe ventilated type cooling; Large-size machine closed-circuit gas cooling.Whether ventilation unit up to standard is provided with fixed-site and be used to check electric machine temperature rise at present, inconvenience is moved, and when motor being carried out the temperature rise check, needs to link to each other with the motor cooling vent through a large amount of the turning by the longer pipe road, its air feed path length, windage are big, can not reach best air feed purpose.
Summary of the invention
The utility model existing be used to check electric machine temperature rise whether ventilation unit up to standard is provided with fixed-site in order to solve, inconvenience is moved, cause when carrying out the temperature rise check for motor, have problems such as wind path is long, windage is big, the controlled air quantity ventilation of a kind of mobile cantilever type unit is provided.
The utility model is to adopt following technological scheme to realize: the controlled air quantity ventilation of a kind of mobile cantilever type unit, comprise the ventilator and the fixing fixed support of ventilator, the fixed support of described fixedly ventilator comprises column, be fixed in the column upper end upper bracket, be fixed in the lower support frame of column lower end, upper bracket and lower support frame are divided into the column both sides; Ventilator is fixed on the upper bracket, and its exhaust outlet vertically downward, and is fixed with the wind conveying pipe road at the exhaust outlet place, is fixed with mobile suspension ring on the upper bracket; Be fixed with the counterweight bucket on the lower support frame.
During use, should winch to motor to be detected place by the ventilation unit, and the wind conveying pipe road that will be fixed in ventilator exhaust outlet place provides wind regime with the cooling air port of motor top is vertical over against fixing in motor, for checking that electric machine temperature rise provides the wind regime condition by crane.Compared with prior art, the utility model adopts portable elevated structure that ventilator is erected, and directly vertical air feed makes that wind path shortens, windage is little, realizes moving the purpose that best wind regime is provided.
The utility model is rational in infrastructure, easy to use and reliable, it is mobile to sling safely, realizes convenient connection the between ventilation unit and the device with the wind, and the use that can between different devices with the wind, replace fast, the full load that is mainly used in ventilation cool motors, generator is tested.
