The utility model relates to a trilobal roots vacuum pump with a magnetic transmission gear. The trilobal roots vacuum pump with the magnetic transmission gear comprises a pump body (1), a coupler (6) and a motor (7). The trilobal roots vacuum pump is characterized in that a driving trilobal rotor (2) and a driven trilobal rotor (3) are arranged inside a pump cavity of the pump body (1); the driving trilobal rotor (2) is meshed with the driven trilobal rotor (3); a driving shaft (4) and a driven shaft (5) are respectively inserted into the driving trilobal rotor (2) and driven trilobal rotor (3); one end of the coupler (6) is connected with the output end of the motor (7); matched magnets (8) are arranged at the other end of the coupler (6) and one end of the driving shaft (4); and the magnets (8) do not contact with one another. The trilobal roots vacuum pump adopts a trilobal transmission mechanism and a magnetic transmission structure, and can adapt to a high-temperature and high-pressure work environment, and the service life of the vacuum pump is prolonged.
Description
Technical field
The utility model relates to a kind of Roots pump, relates in particular to a kind of trilobal Roots pump with magnetic drive device.
Background technique
The drive part of general Roots pump is by motor, coupling and main shaft form, be connected by key between coupling and the main shaft, this mode that is rigidly connected that connects by key is no problem in the normal operation process, but when motor quits work, main shaft since inertia return and be rotated further, be rigidly connected because be, so will inevitably force motor output shaft to turn, this will cause damage for motor, affects the working life of vacuum pump, and Roots pump adopts two leaf driving mechanisms in addition, although rate of air sucked in required is large, the speed of exhaust is stable, but two leaf driving mechanisms are prone to heat exchange phenomenon, can affect the working life of pump under high pressure and high temperature.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of trilobal Roots pump with magnetic drive device is provided, and not only rate of air sucked in required is large, the speed of exhaust is stable, and can adapt to high pressure-temperature, and prevent from motor is caused damage, improve the working life of vacuum pump.
The purpose of this utility model is achieved in that a kind of trilobal Roots pump with magnetic drive device, it comprises the pump housing, coupling and motor, in the pump chamber of the described pump housing, be provided with initiatively three lobe rotor and driven three lobe rotor, and initiatively three lobe rotor and driven three lobe rotor are intermeshing, on described active three lobe rotor and driven three lobe rotor, be interspersed with respectively driving shaft and driven shaft, one end of described coupling links to each other with the output terminal of motor 7, be provided with the magnet that cooperatively interacts at the other end of described coupling and an end of driving shaft, and do not contact with each other between the magnet, described active three lobe rotor and driven three lobe rotor all adopt stainless steel material.
Compared with prior art, the beneficial effects of the utility model are:
The utility model adopts trilobal driving mechanism and magnetic drives structure, on the one hand so that the such gas compression phenomenon of mechanical pump can not occur in pump chamber, can be used to aspirate various dried, wet materials, also can aspirate coercibility steam, and can adapt to the high pressure-temperature working environment, improved the working life of vacuum pump, coolant seal water can guarantee vacuum pump work at normal temperatures, reach energy-saving effect, adopt on the other hand magnetic drives can avoid being rigidly connected of transmission shaft and coupling, prevent from when quitting work, damaging because inertia causes motor.
