And more it is concerned with electromotor self performance, the most more it is concerned with Engine Durability.Turbocharger is high-end engine
Core component, be also main quick-wear part, it is the waste gas inertia impulsive force that utilizes electromotor to discharge in promoting turbine room
Turbine, turbine drives again coaxial impeller, the air that impeller force feed is sent here by air filter pipeline, be allowed to supercharging enter gas
Cylinder, when engine speed speeds, the waste gas velocity of discharge and secondary speed the most synchronize speed, and impeller just compresses more air and enters
Cylinder, the pressure of air and density increase the more fuel that can burn, corresponding increase fuel quantity and the rotating speed of adjustment electromotor,
Increase the output of electromotor.Turbocharger not only increases the internal combustion efficiency of electromotor, and adds power, fall
Low discharge, saves oil consumption.Along with the development of Hyundai Motor, transportation, agricultural machinery and engineering machinery, to diesel engine,
The demand of gasoline engine is increasing, and the technology of turbocharger is required be more and more higher.Modern vapour, Diesel engine all need
Want low emission, high rotating speed, high-performance, low oil consumption and low noise.There is many shortcomings in existing conventional turbocharger, mainly wraps
Including electromotor turbocharger cisco unity malfunction when initial start, work is long for preheating time, and electromotor is when middle high rotating speed
Noise is big, and vibration is big, and exhaust efficiency is low, easily produces high temperature, causes electromotor and other movement parts accelerated wear test or adhesion
Scuffing of cylinder bore, not only produces higher maintenance expense, and adds oil consumption, owing to electromotor is too high often in operating temperature
State, exacerbates scrapping in advance of electromotor.
Utility model content
The technical problems to be solved in the utility model is: the electromotor providing a kind of high rotating speed, low load, power-assisted to rotate is used
Magnetic suspension turbocharging device, the noise overcoming the existence of existing turbocharger is big, and vibration is big, and exhaust efficiency is low, easily produces
The deficiencies such as raw high temperature.
For solving above-mentioned technical problem, this utility model adopts the technical scheme that: this magnetic suspension turbocharging device includes
Heat shield, intermediate, compressor casing, compressor impeller, self-locking nut, also include being placed in heat shield, intermediate and gas compressor blade
Magnetic turbine wheel shaft between wheel, magnetic suspension bearing coordinates socket with magnetic turbine wheel shaft, and magnetic suspension bearing includes inner shell, coil and magnetic
Property plug, magnetic suspension bearing internal circular surfaces and magnetic turbine wheel shaft surface are all helicity lines shape；Magnetic turbine wheel shaft includes leaf
Wheel and axle, the inner and outer round surface helicity ridge orientation matched between magnetic suspension bearing with magnetic turbine wheel shaft is consistent.
Further, the angle between the spiral lamination on magnetic suspension bearing internal circular surfaces and magnetic turbine wheel shaft surface be 35 ° extremely
45 °, on magnetic turbine wheel shaft 2, gash depth is 0.05mm～0.10mm, and width is 0.05mm～0.10mm.
Further, magnetic suspension bearing is two, is separately mounted to the left and right sides on magnetic turbine wheel shaft.
The technique effect that this utility model reaches specifically includes that 1, install two on housing due to magnetic suspension turbocharging device
Part magnetic suspension bearing 1 and a magnetic turbine wheel shaft 2, meet low emission, high rotating speed, high-performance, and low oil consumption and low noise start
The technology requirement of machine.Magnetic suspension bearing 1 and the application of magnetic turbine wheel shaft 2 so that between magnetic suspension bearing 1 and magnetic turbine wheel shaft 2
Not having Mechanical Contact, the most there is not abrasion, have operation noise little, energy consumption is low, and the life-span is long, it is not necessary to lubrication, oil-free pollution etc.
Advantage, it is achieved that green run, eliminate inflammable lubricant can the danger of fire hazard simultaneously.
2, magnetic suspension bearing 1 rotates the least resistance to magnetic turbine wheel shaft 2, and therefore energy loss is the least, is beneficial to joint
Can, more than 15% efficiency can be improved than conventional turbocharger.
3, can farthest reduce, by accurately control, the turbine wheel shaft caused by Impeller Mass imbalance to beat, reduce whirlpool
The vibration that wheel shaft causes under critical speed state.
4, magnetic suspension turbocharging device can start work with electromotor simultaneously, and can be not required to the waste gas that electromotor is discharged
Drive and also can operate voluntarily, do not increase electromotor initial start load；Contribute to engine combustion fully, power improve, reduce
Discharge, saves oil consumption etc..
