Description
Technical field
The invention belongs to the air compressor technical field, more particularly relate to the design of the air compressor that adopts variable frequency speed-pressure regulation.
Background technique
The output of traditional air compressor can only be fluctuateed in certain scope around certain pressure.Generally with the starting of pressure control switch or pressure governor control motor with close, substantially within the specific limits with delivery pressure control.That is cross when low when delivery pressure, actuating motor running, and then drive compression cylinder operation improve the pressure in the gas holder; When delivery pressure was too high, disable motor shut down, and the pressure in the gas holder is reduced.
Existing air compressor delivery pressure can only be controlled at fixing among a small circle in, can not set or adjust pressure in the larger context, and pressure control is also not accurate enough at all.In addition, its motor is full speed running when work, and therefore power consumption is big, operating cost is high.
Summary of the invention
Purpose of the present invention just is to overcome above-mentioned shortcoming and defect, and a kind of air compressor that adopts variable frequency speed-pressure regulation is provided.It can set or adjust pressure in the larger context, and and then with delivery pressure be controlled near this setting value one more among a small circle in, and pressure control is also more accurate.In addition, low, the good energy-conserving effect of its power consumption.
In order to achieve the above object, the present invention includes frame, rack-mounted gas holder, be fixed on the crankcase on the gas holder, be installed in the compression cylinder on the crankcase, be fixed on the motor on the crankcase, the pistons work in the motor driving compression cylinder, pipeline and the valve thereof of connection between compression cylinder and gas holder is arranged on gas outlet valve and safety valve on the gas holder.The valve of above-mentioned connection between compression cylinder and gas holder is three-way valve, connecting tracheae on the 3rd path of three-way valve, and the other end of tracheae is installed with pressure transducer.Pressure transducer is connected with the single-chip microcomputer comparison controller with pointer-type or digital pressure gauge with lead respectively.Pointer-type or digital pressure gauge also are connected with the setting regulator respectively with the single-chip microcomputer comparison controller, and the single-chip microcomputer comparison controller is connected to variable-frequency governor with the comparison value input again, and variable-frequency governor is connected between power supply and the motor to regulate rotating speed of motor.Pointer-type or digital pressure gauge have sets the throw over switch that shows and work and show, pressure transducer is connected with pointer-type or digital pressure gauge through throw over switch with the setting regulator again.
Set regulator and have two setting buttons, one is set button for rising, and it two sets button for descending.Rise to set button and be used to desire the rising of setting value when big and set, also be about to " adding " that currency bring up to when desiring setting value set than currency; Descend to set button and be used to desire setting value and set, also be about to " subtracting " that currency drop to when desiring setting value and set than the decline of currency hour.
Said pressure transducer can adopt the semiconductor pressure resistance sensor.The transducing signal of semiconductor pressure resistance sensor is strong, signal to noise ratio is high, processing of circuit is convenient, and using effect is good.
Variable-frequency governor can adopt prior art.99109144.2 number patent discloses a kind of like this prior art.
The present invention is work like this: behind start, the air compressor working stability, check at first whether the show value of pointer-type or digital pressure gauge meets the requirements.If undesirable, throw over switch should be transformed into and set demonstration, the setting value of adjusting pointer-type or digital pressure gauge then is to needed force value.After setting is finished, throw over switch is transformed into work shows.
In the working procedure of air compressor, the single-chip microcomputer comparison controller is the measured value of monitor force sensor at any time subsequently, and itself and setting value are compared.If the error of the comparison value overshoot of measured value and setting value, the single-chip microcomputer comparison controller will be assigned speed-regulating instruction to variable-frequency governor, and variable-frequency governor will drive motor quickens or slows down, and pressure in the gas holder is increased or reduces.If the comparison value of measured value and setting value does not have the error of overshoot, the single-chip microcomputer comparison controller is not assigned speed-regulating instruction, and it is constant that motor can be kept former rotating speed.Meanwhile, the measured value of sensor can be presented on pointer-type or the digital pressure gauge at any time.
Task of the present invention comes to this and finishes.
The present invention can set or adjust pressure in the larger context, and and then with delivery pressure be controlled near this setting value one more among a small circle in, and pressure control is also more accurate.Low, the good energy-conserving effect of its power consumption.But its wide popularization and application is in all trades and professions.
