Description
Technical field
The utility model relates to a kind of magnetic coupling, at high temperature transmits power or moment by the magnetic line of force across partition.
Background technology
The maximum temperature limit that common magnetic coupling uses is by the serviceability temperature decision of permanent magnet.At present, what serviceability temperature was the highest at present is the Sm2Co17 rare earth permanent magnet, is 250 ℃.The operating mode that surpasses this temperature can't be used magnetic drive pump.
Summary of the invention
The purpose of this utility model provides a kind of being used at the shaft coupling that surpasses on the magnetic drive pump of working under 250 ℃ the operating mode.
The utility model is a kind of electromagnetic type inductance loop asynchronous coupling, the external rotor of drum shape connects with machine shaft, the axis of external rotor is coaxial with machine shaft, the axis of the drum shape internal rotor of making by hysteresis material and the axis coaxle of external rotor, the drum shape separation sleeve of being made by nonmagnetic substance is installed between external rotor and internal rotor, internal rotor is installed in the separation sleeve, in the drum wall inboard of external rotor, around armature is installed, the drum wall installation site in the axial direction of internal rotor is corresponding with armature.
Usefulness of the present utility model is: because of internal rotor does not have permanent magnet, its Applicable temperature can be used for more than 450 ℃.
Description of drawings
Fig. 1 is a structure diagram of the present utility model.
Embodiment
Figure 1 shows that, the structure of electromagnetic type inductance loop asynchronous coupling, the external rotor 1 of drum shape connects with machine shaft, the axes O O ' of external rotor 1 is coaxial with machine shaft, the axis of the drum shape internal rotor of being made by hysteresis material 4 is coaxial with the axes O O ' of external rotor 1, the drum shape separation sleeve of being made by nonmagnetic substance 3 is installed between external rotor 1 and internal rotor 4, internal rotor 4 is installed in the separation sleeve 3, in the drum wall inboard of external rotor 1, around armature 2 is installed, the drum wall installation site in the axial direction of internal rotor 4 is corresponding with armature 2.
The structure of the utility model shaft coupling can become static seal with movable sealing, has solved the leakage problem of medium; Made by hysteresis material because of internal rotor 4, no permanent magnet, its Applicable temperature can be used for more than 450 ℃; Its drive mechanism is the flexible transmission of non-contact type, vibrates for a short time, and noise is little, has prolonged the bearing life of machine; When overburden, can carry out overload protection automatically, cause inner and outer rotors to trackslip or stall; Rotation speed change in a big way in, magnetic coupler all has higher efficient; Carry hot liquid viscosity when " cold start-up " bigger, shaft coupling of the present utility model during starts can produce bigger slip, and along with liquid temperature rise and viscosity diminish, rotating speed of the present utility model also and then raises.Be that machine can be in " cold start-up "; Carry when containing the ferrite powder of higher percent in the liquid, because there is not permanent magnet in the pumped (conveying) medium in shaft coupling of the present utility model through the zone, so can not cause the iron powder post to accumulate in the shaft coupling.
