Description
Technical field
The present invention relates to a kind of rail traffic rising bow pumping units, and in particular to a kind of oil-free brushless rising bow pump of direct current.
Background technique
Currently, be expert at industry extensive application is the rising bow pump based on brushed DC motor, the liter based on brushed DC motor
Bow pump is easy to produce the demagnetization of magnetic steel of motor piece under high humidity hot environment for a long time, in turn results in electricity without overcurrent and overheating protection
Electrical-mechanical performance changes, and the IP degree of protection that brushed DC motor needs to use is higher, higher dust-proof playing
But also motor radiating is bad while waterproofing protection acts on, so scene generally requires the working time to be less than 15min.While by
Single cylinder can only be used by pumping in the structure limitation (to fill collector ring and carbon brush) of brushed DC motor, but be met biggish
Capacity and compression ratio can only increase piston stroke, certainly will will increase operational shock earthquake intensity and sound level in this way.And rotor
The centrifugation torque that rotation generates can be applied to body and also will increase vibration severity.In addition, can not be by cylinder after reaching rated pressure
Compressed gas is laid down in head, be will cause required starting torsion when low voltage starting in this way and is increased, the immediate current of motor and temperature rise are prominent
So increase, shortens electrical machinery life, increase the abrasion to bearing.
It is therefore desirable to a kind of rising bow pump be designed, to realize better using effect and more preferably practicability.
Summary of the invention
The purpose of the present invention is to provide a kind of direct current it is oil-free it is brushless can pressure release rising bow pump, it is existing based on there is brush to solve
The big problem of the rising bow demand pump degree of protection height and detent torque of direct current generator.
To achieve the above object, the present invention adopts the following technical scheme:
A kind of direct current it is oil-free it is brushless can pressure release rising bow pump, the rising bow pump by oil-free brushless motor, controller, compressor,
Valve, relief valve and DC-DC power source composition；The oil-free brushless motor uses direct current supply, motor output shaft connect compressor；
The compressor output end connects output channel, and the end connecting valve of output channel directly passes through three in valve and compressor
Port valve connects relief valve；The DC-DC power source is used to ± 30% direct current of DC110V being converted to DC48V direct current；In use,
Under the control of the controller, when needing to external pressurized, controller control is oil-free brushless for oil-free brushless motor, valve and relief valve
Motor operating, drive compressor operation, at this time valve open, relief valve close, when reach need pressure value when, oil-free brushless electricity
Machine stops, and valve closure, relief valve automatically opens at this time, and the gas between compressor and valve in pipeline is discharged, for compression
Machine pressure release, so that the torque minimum that oil-free brushless motor is required when being again started up.
Preferably, above-mentioned compressor selects the compressor of the double counter-rotating designs of double cylinders.
Preferably, above-mentioned valve is solenoid valve.
Preferably, above-mentioned relief valve is solenoid valve.
The present invention has the advantage that
After design of the invention, the advantages of having had both Traditional DC motor, while carbon brush, slip ring knot are eliminated again
Structure；Design of the invention has that small in size, light-weight, power output is big, and torque characteristics is excellent, in, low speed torque performance it is good, starting turns
Square is big, and starting current is small, can stepless speed regulation, speed adjustable range is wide, and overload capacity is strong, and soft start and soft stop, braking characteristic are good, can save original
Some mechanical brakings or electro-magnetic braking device, it is high-efficient, it is lost without excitation loss and carbon brush, eliminates multi-stage speed-reducing loss,
Integrated power-saving rate is up to 20%~60%.The system of optimization designs, so that system reliability is high, stability is good, adaptable, dimension
It repairs with maintenance simply, resistance to vibration of jolting, low noise, vibration is small, and smooth movement, the service life is long, and required degree of protection is low, does not generate fire
Flower is particularly suitable for explosivity place；Compared with original system, better using effect and more preferably practicability are obtained.
