Description
Technical field
The present invention relates to a kind of speed regulating device, specifically a kind of perfect heat-dissipating and there is the water-cooling type permanent-magnet speed governor of explosiveproof isolation function.
Background technology
The patent No. is ZL200920256058.7 Authorization Notice No. is CN201577019U, authorized announcement date is the utility model patent on September 8th, 2010, disclose a kind of permanent-magnet speed governor, it comprises: tubular conductor rotor, tubular p-m rotor and adjuster, it is characterized in that tubular p-m rotor is in tubular conductor rotor, separated by air-gap therebetween, and independently rotate with the rotating shaft installed separately; Adjuster regulates tubular p-m rotor and tubular conductor rotor at the relative position of axis direction, to change the active area between tubular conductor rotor and tubular p-m rotor, realizes the size changing transmitting torque between tubular conductor rotor and tubular p-m rotor.
Above-mentioned permanent-magnet speed governor has following deficiency:
1, above-mentioned permanent-magnet speed governor does not have water-cooling system, the heat generating components (mainly conductor rotor, power shaft and output shaft) of equipment can only by carrying out heat exchange cooling with its ambient air, equipment can produce lasting eddy current field when running in conductor rotor, the generation of eddy current field can make the temperature of conductor rotor constantly raise, in the process that conductor rotor temperature raises, ambient air itself is also heated, so only carry out heat exchange to lower the temperature being inadequate by conductor rotor and its ambient air, and along with the rising cooling-down effect of temperature can be worse and worse; In equipment running process, power shaft and output shaft are all at High Rotation Speed, temperature also can be more and more higher, the same with conductor rotor, along with the rising of temperature is only carried out heat exchange to lower the temperature also being inadequate by axle and its ambient air, along with the continuous rising of temperature, cooling-down effect also can be worse and worse.Particularly powerful permanent-magnet speed governor, the power (torque) transmitted is larger, the speed heated up is also faster, in equipment running process, the too high normal operation that can affect equipment of the temperature of equipment unit, also can shorten the useful life of equipment simultaneously, and the larger permanent-magnet speed governor of power is only operationally be difficult to normal work by Temperature fall, the power not having the permanent-magnet speed governor of water-cooling system to transmit will be restricted, and is unfavorable for the product development of high-power permanent magnet speed regulator.
2, above-mentioned permanent-magnet speed governor does not have explosion-proof cavity, do not possess explosion prevention function, should not run in containing the environment of flammable explosive gas, such as can not use the permanent-magnet speed governor not having explosion-proof cavity under mine, if in explosion-proof cavity, an explosion occurred, because there being the tight isolation of explosion-proof cavity, this blast would not expand to outside explosion-proof chamber, avoid the possibility that wider blast occurs, vice versa, if explosion-proof chamber is external, an explosion occurred, because there being the tight isolation of explosion-proof cavity, this blast also can not expand in explosion-proof chamber, avoid the impact that extraneous explosion may produce permanent-magnet speed governor, the normal operation of equipment can be ensured.
