The nut of rotating shaft socket fix, described matrix is sealed positioned at motor lower position by closure, and described cavity is correspondingly
The overcentre position of impeller is vertically disposed with air inlet, and the side wall of the cavity is provided with the outlet along impeller tangential direction arrangement
Mouthful.
Supplement as the one kind to technical scheme described in the utility model, described motor selects one-way motors.
Supplement as the one kind to technical scheme described in the utility model, described closure lower end is provided with magnetic field biography
Sensor, the magnetic field sensor is withstood by control chip, and magnetic field sensor is used for detecting motor speed.
Supplement as the one kind to technical scheme described in the utility model, described matrix upper end is near gas outlet position
Pressure transducer is installed, pressure transducer is used for detecting the gas pressure of outlet side.
Supplement as the one kind to technical scheme described in the utility model, described base bottom is provided with lower cover.
Beneficial effect
This utility model is related to a kind of gasoline vapor purifier for preventing bearing swash, by controlled motor rotate so as to
Impeller rotates, and so as to form pressure differential, oil vapour is sent into into inlet manifold, it is to avoid in being discharged to air, realizes reducing discharge
Requirement；Step on machine shaft and nut screw connection fixing bearing, prevent bearing swash, reduce bearing swash and gasoline is steamed
The impact of the work efficiency of vapour purification.
