Technical field
The utility model relates to a kind of cooling system, particularly relates to a kind of speed governing permagnetic synchronous motor bearing shell lubricating and cooling system.
Background technique
Synchronous machine is the same with induction machine is a kind of conventional AC motor.Synchronous machine is a kind of novel high-efficiency and energy-saving product, it possess the shape of high stability, high efficiency, simple in structure, motor and size can be versatile and flexible etc. remarkable advantage.
The patent No. is that the Chinese patent of CN201120454507.6 discloses a kind of cooler of electric motor, comprise the radiating fin that adopts aluminium matter or copper material to make, in the form of sheets or needle-like, the other end is the bolt that use is installed in one end of described radiating fin, and described bolt is provided with outside thread.In the utility model, as further improvement, described bolt is provided with internal thread.The utility model is simple in structure, making is easy, cost is low and easy for installation, and the supplementary equipment that can be used as cooler or cooler is used, and can make the temperature of motor each several part basically identical.But, under synchronous machine normal operation, due to core loss, eddy current loss, mechanical loss etc., cause motor internal to produce heat, if can not dispel the heat in time, can have a huge impact motor body performance so.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of speed governing permagnetic synchronous motor bearing shell lubricating and cooling system, and it can take away rapidly heat, reaches good cooling effect.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of speed governing permagnetic synchronous motor bearing shell lubricating and cooling system, it is characterized in that, it comprises cooler bin, lid, liquid port, strut, cylindrical shell, cross bar, indicator, screw rod, pressure gauge, liquid container, through rod, lid is positioned at a side of cooler bin, liquid port is positioned at the bottom of cooler bin, strut, cylindrical shell is all fixed on the top of cooler bin, cross bar and strut are fixed, indicator is positioned at the top of liquid container, screw rod is positioned at the below of cross bar, pressure gauge, indicator is all connected with through rod, through rod is positioned at the top of cross bar, one end of cross bar is connected with liquid container.
