Description
Technical field
The present invention relates to coupling speed adjusting technique fields, and in particular to a kind of axial direction engagement area adjustment type permanent magnet coupling speed governing
Device.
Background technology
China is energy consumption big country, and energy reserves is insufficient, and energy utilization rate is relatively low, energy-saving to have become whole society's concern
Emphasis.Wind turbine, water pump load are the commonly used equipments having a large capacity and a wide range, and energy consumption accounts for very big ratio in alternating current generator total energy consumption
Example.The power consumption of electric motor system accounts for the 60% of national power consumption, and wherein wind turbine electricity consumption accounts for the 10.4% of national total electricity consumption, pump
Class motor accounts for 20.9%, and compressor accounts for 9.4%, and air conditioner refrigerating device accounts for 6%, and wind turbine, pump class power consumption are very huge, yet with wind
The outmoded backwardness of driving equipment of machine, water pump etc., operational efficiency lower than Foreign Advanced Lerel 10%~20% are annual to waste electric energy extremely
Seriously, there is very big energy conservation potential.
Speed governing is known as the optimal power save mode of motor in the world, if using speed regulating control to wind turbine, load of the pumps,
It economizes on electricity up to 20%~70%, and not only power savings are notable, and the requirement for meeting production technology, ensure the matter of product
Amount, plays the role of very important, and economic benefit is very notable.Maximum breakthrough is fluid coupling and frequency converter herein
Generation and application, it greatly improves productivity and the Optimum utilizations of the energy, make this theory of energy conservation and environmental protection in engineering machinery
Application among be fully reflected.
Fluid coupling transfers turning for motor input during work as a kind of common speed control device using liquid medium
Speed, its shaft end that is actively entered are connected with motor driving shaft, and driven output shaft end couples with load shaft end, are situated between by adjusting liquid
The pressure of matter, to change the rotating speed of output shaft.In the ideal situation, when pressure tends to infinity, output speed turns with input
Speed is equal, is equivalent to positive coupling；When the pressure decreases, output speed accordingly reduces, and continuously changes pressure medium, and output turns
Speed can obtain the stepless time adjustment less than input speed, speed-regulating range width, and simple in structure, and failure rate is low, to required precision
It is low, there is certain energy-saving effect.However, gradually ripe in fluid coupling product and after being widely applied, inferior position also by
Fade in it is existing, as energy conversion efficiency is low, and hydraulic oil will regularly replace, and adjusting speed accuracy is low etc..It is fast with microprocessing afterwards
Speed development and the development of VVVF speed regulation, in middle and later periods the 1980s, the converter technique of developed country starts gradual reality
With change, this new product of frequency converter is gradually known and extensive use.

Change the purpose of supply voltage, so as to the supply voltage for being supplied to motor practically necessary, and then energy saving, speed governing mesh
, fluid coupling is better than in performance.But as frequency converter is applied on a large scale in a device, it insufficient and bad
Gesture also gradually highlights, and the interference of frequency converter is its maximum inferior position.Frequency converter interference mainly has：It is first, general in frequency converter
All over the non-linear rectifying device such as thyristor or rectifier diode has been used, the harmonic wave generated will generate Conduction Interference to power grid,
Network voltage is caused to distort（Voltage distortion rate represents that THDV is 10~40% or so caused by frequency converter generates harmonic wave with THDV）,
Influence the power supply quality of power grid；Second is that the output par, c of frequency converter is generally adopted by the switching devices such as IGBT, in output energy
While will generate stronger electromagnetic interference on the output line, influence the normal work of periphery electric appliance.In addition, motor with
In the rigid connection of load, mechanical stability against short circuit and safety issue are caused since alignment is bad, invariably requirement it has been proposed that
More preferably scheme is come the shortcomings that making up existing frequency converter.
