Abstract
The utility model belongs to a ventilating system, comprising a main motor, an auxiliary motor, an overdrive clutch, a shaft coupler, etc. The air conditioning system of the power injection dispensing workshop for the medicine industry mainly adopts a centrifugal wind fan. In general the centrifugal wind fan is driven by one single motor totally. Depending on opening and closing wind doors, adjusting the wind quantity and the wind pressure is implemented. When the variation of the wind quantity and the wind pressure is large, the loss of the power is very large. The technique of the variable frequency speed control is adopted to implement the adjustment of the wind quantity and the wind pressure. Because the expense is higher, the application is very little. The utility model saves electricity, and the utility model saves energy. The utility model has the advantages of simple structure and convenient operation. The utility model can implement the function of transforming the two revolution speeds of the wind fan. The utility model is an ideal equipment of the power injection dispensing workshop for the medicine industry.
Description
The utility model belongs to ventilation system, is specially a kind of double speed dual-motor blower fan.
Medical industry powder-injection packing workshop air-conditioning system mainly adopts the centrifugal fan air-supply at present.Centrifugal fan generally all is the separate unit motor driving, and adjusting air quantity, blast are realized by the switch air door.When air pressure air flow changed greatly, power loss was very big.The adjusting of adopting variable-frequency control technique to realize airflow pressure is also arranged.Domestic low power frequency conversion device is used more, and when power was big, because the one-time investment number is big, reliability was not high, so use seldom.
The purpose of this utility model is to provide a kind of economize on electricity, energy-conservation, simple in structure, easy to use, can realize the blower fan of two kinds of rotating speeds of conversion blower fan.
The utility model is achieved in that blower fan is on the vibration damper base, in bearing box, bearing support front, be connected by coupling between main motor and the bearing box, main motor the other end axle links to each other with free wheel device, the belt two ends are connected on free wheel device and the belt pulley, and helper motor is installed on the shock absorber bearing.
Advantage of the present utility model is to economize on electricity, energy-saving effect is remarkable, simple in structure, easy for operation, is the ideal equipment in medical industry powder-injection packing workshop.
Fig. 1 is the utility model principle schematic.
1-bearing support, 2-blower fan, 3-bearing box,
4-coupling, 5-master's motor, 6-free wheel device,
7-belt, 8-helper motor, 9-belt pulley,
10-vibration damper, 11-vibration damper base.
The utility model is described in further detail below in conjunction with accompanying drawing: two motors is respectively established a power switch, controls the start-stop of two motors respectively.Main motor and helper motor do not start simultaneously.When main as required electric motor starting is worked, drag fan operation by main motor.This moment, free wheel device was operated in separated state.When needs, cut off main motor power, start the helper motor power supply.Helper motor drags free wheel device by belt, makes the free wheel device combination, drags main motor shaft by free wheel device, drags the blower fan running through main motor front end coupling.This moment, main motor played transmission shaft.During main machine operation, free wheel device is operated in separated state, and belt pulley, belt and helper motor all remain static.
