Abstract
The utility model relates to an air compressor and a control mechanism, which comprises a motor, an air compressor, a gas storage tank and a controller. The compressed air inlet pipe of the gas storage tank is provided with a three-way pipe; three ports of the three-way pipe is connected with a unloading valve outlet, a pressure sensor and a gas storage tank respectively; the unloading valve inlet is connected with a compressed air outlet pipe of the an air compressor; the pressure signal output of the pressure sensor is connected with the controller. Since the unloading valve is used, the air compressor can be started under an ordinary pressure of outlet so as to reduce the impact force of starting current of the motor and the compressor; the pressure sensor and the controller are used to arrange or regulate pressure within a wider range; and the output pressure can be then controlled within a smaller range around the setting valve; and the pressure control is more accurate and intuitive. The device is of energy consumption with good energy-saving effect.
Description
Technical field
The utility model relates to the air compressor technical field, particularly a kind of pressure air compressor of control automatically that has.
Background technique
Air compressor has been widely used in the middle of industry, agricultural, traffic, national defence, the life.Therefore the reliability of air compressor, degree easy to use, energy-saving effect etc. there is higher requirement.
The pressurized air output of the air compressor of prior art is to fluctuate in certain scope around certain setting pressure.Usually with the starting of pressure relay or pressure governor control motor, stop, substantially can be within the specific limits with delivery pressure control.When delivery pressure is reduced to a certain setting value, the motor starting running, air compressor improves the pressure in the gas holder; When delivery pressure is higher than a certain setting value, close motor and stop the air compressor running, the compressed air pressure in the gas holder is remained in certain scope.
The defective of the air compressor of prior art is a setting pressure or adjust pressure in the larger context, and pressure control is also not accurate enough; Its motor the time is at full speed in work, starting under load, thus the starting current height, power consumption is big, operating cost is high, bigger to the influence in working life of equipment.Pressure relay control is that contact circuit control is arranged, and its defective is conspicuous.
Summary of the invention
In order to address the deficiencies of the prior art, the utility model discloses a kind of air compressor and controlling method.Concrete structural form is between the compressed air outlet pipe of air compressor and gas holder three-way pipe to be set.One end interface of three-way pipe connects gas holder; One end interface connects the unloading valve outlet, and the unloading valve inlet connects air compressor compressed air outlet pipe; An other end interface of three-way pipe connects pressure transducer, and the signal output part of pressure transducer connects controller.
Unloading valve be a single current with safety check function to valve, when entry end pressure was higher than outlet end, unloading valve was a path; When unloading valve entry end pressure or entry end pressure identical with outlet end pressure was lower than outlet end pressure, unloading valve cut out, the pressure off-load of entry end when unloading valve cuts out.Unloading valve commonly used has two kinds: a kind of be the automatic deloading valve, a kind of be electronic unloading valve.Since be provided with unloading valve, the air compressor prestart, and the compressed air outlet that can keep air compressor is a normal pressure.
Pressure transducer is one pressure signal is converted to the device of electrical signal, and when pressure signal changed, the electrical signal of its output was along with variation, and electrical signal reaches controller, by sending command signal after controller and the comparative analysis of set pressure data.
Controller is a microelectronic component, is provided with the control gear that power supply module, single-chip microcomputer, frequency changer circuit, switching circuit, digital display, control knob etc. are formed.
The realization technical solution adopted in the utility model is: a kind of air compressor and control mechanism are to be made of motor, air compressor, gas holder, controller, it is characterized in that: on the compressed air inlet pipe of gas holder three-way pipe is set, three interfaces of three-way pipe connect unloading valve outlet end, pressure transducer and gas holder respectively; The unloading valve entry end connects air compressor compressed air outlet pipe; Pressure transducer pressure signal output terminal connects controller; Motor power line connects controller, by the starting of controller control air compressor with stop.
Unloading valve is automatic deloading valve or automatically controlled unloading valve.
Pressure transducer is the electrical signal pressure transducer.
Controller is the single-chip microcomputer micro controller, is made of power supply module, single-chip microcomputer, switching circuit, digital display, control knob, and controller is connected with power supply, motor, pressure transducer, unloading valve respectively by circuit.
Be provided with the frequency changer circuit of control motor speed in the controller.
Control button on the controller panel is provided with starting button, button is set, upper pressure limit preset button, low pressure limit preset button.
Working procedure of the present utility model is: connect power supply, and starting air compressor, behind the facilities for observation working stability, the working pressure of setting controller (upper limit pressure and threshold pression) numerical value, the controller display screen of controller is set to the gas receiver pressure-display again.When gas receiver pressure reached the maximum working pressure of setting, the electrical signal of pressure transducer reached controller, and controller sends instruction with after the electrical signal of sensor and the pressure value comparative analysis of presetting setting, and motor shuts down, the unloading valve off-load; The following of working pressure that drops to setting when gas receiver pressure prescribed a time limit, and controller sends instruction, motor starting, and air compressor work is again to gas receiver inflation, periodic duty so repeatedly.
The beneficial effects of the utility model are: owing to used unloading valve, air compressor is started under the outlet normal pressure, reduce the starting-impact power of the starting current and the compressor of motor; 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 also accurately, directly perceived.Low, the good energy-conserving effect of its power consumption.But its wide popularization and application is in all trades and professions.
