Abstract
The invention belongs to the technical field of mechanical design and relates to a device for sucking carbon powder in a motor. The device comprises an air suction cylinder (6), a carbon collection net (9), an air-entraining tube (1), an air suction tube (5), a regulating switch (8) and a micro pressure gauge (3). The device employs an air injection suction principle, is powered by compressed air that is frequently used in test rooms, realizes an air suction function through an air suction device and inlet flow regulation, and achieves the purpose of micro-pressure air suction by regulating air flow at an inlet; and meanwhile, no carbon powder is discharged into air by virtue of filtration so that pollution is avoided. The device has the advantages of simple structure, low cost, convenience in use, accurate control, no environmental pollution, continuous working, no maintenance and the like.
Description
Technical field
The invention belongs to technical field of mechanical design, relate to the device of carbon dust in a kind of suction motor.
Background technology
Aircraft fuel system DC electropump, by DC motor Driver, has the parts such as diverter, carbon brush in motor, in work
During, the carbon dust that carbon brush abrasion gets off can accumulate in inner chamber, if got rid of not in time, will affect the conduction energy of diverter
Power, accelerate the abrasion of carbon brush, affect life-span of motor, time serious, influence whether the fuel feeding of fuel pump and completing of aircraft task.
Aboard, the carbon dust of inner chamber is inhaled by the flowing that the low pressure port of motor cavity is generally placed in the low-pressure area of aircraft, beneficially air
Out, it is ensured that the normal use of product.But under surface condition, in the life test of fuel pump and direct current generator, it is also desirable to mould
Intend aircraft working environment, to causing a small negative pressure in the vented cavity of pump, the carbon dust accumulating in motor cavity sucked out,
To improve the service behaviour of motor, reduce carbon distribution and cause the danger of short circuit.The method of industrial employing has vacuum pump or air pump
The mode of suction, because this negative pressure value is smaller, only (20～50) mm water column pressure, it is difficult to realize or control, use cost
High；In actually used, use regular compressed air after work a period of time to blow out carbon dust, or motor back cover is taken apart clean
The method of carbon dust, it is impossible to realizing work continuously, the carbon dust simultaneously blown out has a strong impact on environment.
Summary of the invention
The purpose of the present invention: for problem above, proposes a kind of device of carbon dust in aspirating and collect motor.This
Bright technical solution is: the device of carbon dust in a kind of suction motor, it is characterised in that: include compressed air inlet pipe 1,
Stress test pipe 2, micro-pressure gauge 3, exhaustor 4, by trial product exhaust tube 5, gas collection precipitation cylinder 6, blow-off pipe 7, carbon collecting net 9；Pressure
Contracting air inlet duct 1 is connected with exhaustor 4, stress test pipe 2, exhaustor 4, is accessed gas collection precipitation cylinder 6 by trial product exhaust tube 5
In, exhaustor 4 and gas collection precipitation cylinder 6 junction are provided with carbon collecting net 9, are connected with blow-off pipe 7 bottom gas collection precipitation cylinder 6.
On the top of pressure measuring tube 2 equipped with micro-pressure gauge 3 for measuring the pressure of exhaust tube 5, when pressure is unsatisfactory for wanting
When asking, can be by the regulation switch 8 regulation force value on compressed air inlet pipe 1 pipeline so that it is using the scope required
In, generally 20～50mm water column.
Micro-pressure gauge 3 can use Pressure gauge.
Equipped with regulation switch 8 on compressed air inlet pipe 1.
Advantages of the present invention and beneficial effect: present invention employs the principle of air ejection suction, utilize test chamber to commonly use
Compressed air be power, regulated by air extractor and inlet flow rate, it is achieved that the function of gas bleeding, regulate intake air
The size of flow, reaches the purpose that micro-pressure is bled, and meanwhile, by filtration, carbon dust is not discharged in an atmosphere, does not causes
Pollute, this patent simple in construction, with low cost, easy to use, precise control, work free from environmental pollution, continuous, need not safeguard
Etc. advantage.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention
Fig. 2 is the application example schematic diagram of the present invention
Detailed description of the invention
The present invention is described in further detail below in conjunction with the accompanying drawings.
Bleed carbon collecting device by compressed air inlet pipe 1, stress test pipe 2, micro-pressure gauge 3, exhaustor 4, by trial product
Exhaust tube 5, gas collection precipitation cylinder 6, blow-off pipe 7, regulation switch 8, collection carbon 9；Compressed air inlet pipe 1 is connected with exhaustor 4, pressure
Testing tube 2, exhaustor 4, being accessed in gas collection precipitation cylinder 6 by trial product exhaust tube 5, exhaustor 4 sets with gas collection precipitation cylinder 6 junction
There is carbon collecting net 9, be connected with blow-off pipe 7 bottom gas collection precipitation cylinder 6.Compressed air inlet pipe 1 accesses source of the gas, and compressed air is passed through
After regulation switch 8, compressed air flows out from exhaustor 4, and air in gas collection precipitation cylinder 6 is extracted out the pressure made in gas collection precipitation cylinder 6
Power relative atmospheric pressure is negative pressure, and bleeding point 5 is connected with gas collection precipitation cylinder 6, and the pressure of bleeding point 5, also below atmospheric pressure, is taken out
Trachea 5 is connected with motor, and in motor, the gas with carbon dust is drawn into gas collection precipitation cylinder from exhaust tube 5 due to gas pressure
In 6, the gas with carbon dust of suction is when the carbon collecting net 9, and carbon dust is stayed in cylinder, and clean gas is discharged by air vent 4
In air；Receive micro-pressure gauge 3 of pressure measuring tube 2 for measuring the pressure of exhaust tube 5, when pressure is unsatisfactory for requiring,
Can be by the regulation switch 8 regulation force value on compressed air inlet pipe 1 pipeline so that it is using in the range of requirement, one
As be 20～50mm water columns.The pollutant such as device worked after a period of time, the carbon dust being sucked out can be deposited on gas collection precipitation
In cylinder 6, periodically can discharge from the end-of-the-pipe 7 being arranged on bottom.
2 pairs of present invention application are described in further detail below in conjunction with the accompanying drawings.
Connecting compressed air inlet source of the gas, carbon collecting device of bleeding produces negative pressure, and the pressure in suction channel 5 is less than motor
The pressure of 1 inner chamber, enters into the gas collection precipitation cylinder 6 of suction carbon collecting device with gas suction channel 11 in product of carbon dust
In, gas is after carbon collecting net 9, and carbon dust is stayed in cylinder, and clean gas is discharged in air by air vent, it is ensured that extract electricity continuously out
Carbon dust in machine.The device designing production by the present invention has been used in the life test of many types of product, substitutes vacuum pump and tune thereof
The function of joint system, has reached good effect, has saved substantial amounts of use cost and maintenance cost, and the most this operation more can
The duty of simulated aircraft.The micro-pressure that this patent uses bleeds the method for de-carbon powder can be capable in industry, medical treatment, environmental protection etc.
Industry is used in the equipment of brush DC motors.
