Background technique
Air compressor is the main body in the compressed air source unit, and it is the device that the mechanical energy of prime mover (being generally motor) is converted to the gas pressure energy, is compressed-air actuated pressure generator.
Controlling component on traditional air compressor mainly is pressure switch and pressure gauge, and pressure switch can be controlled automatically by air pressure, also can be used for hand push button and carry out manual control.When the gas holder internal air pressure was elevated to the predefined shutdown pressure of pressure switch, switch was with regard to automatic disconnection, and such regulative mode not only precision is inadequate, also can cause the pressure of enduring, start shooting to depart from setting value because of wherein being used for the camber of spring of control.
At present, air compressor adopts electronic control system more, can reach to adjust accurately, and can observe very intuitively the working state of air compressor by liquid crystal digital display.
We know and are provided with an oil circulating system and prime mover in the air compressor, and wherein oil circulating system comprises an oil cut-off valve.Air compressor is when operation; oil in the oil circulating system can produce high temperature, and equipment is when going wrong, and we usually can open first oil cut-off valve and derive oil in the oil circulating system; and the oil temperature in the oil circulating system is very high, or easily makes the maintenance operator be subject to certain injury.And the operation quality of prime mover has directly affected the economic benefit of enterprise, works under the state of excess Temperature, and causes fault, not only makes operator have certain potential safety hazard, and has affected the economic benefit of enterprise.
Summary of the invention
The utility model is for deficiency of the prior art, a kind of air compressor control system is provided, can observe the temperature of oil circulating system and prime mover in the equipment, thereby it is adjusted, reduced operator's potential safety hazard, reduce the rate of fault of equipment, improved the economic benefit of enterprise.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of air compressor control system is included as the power supply of system power supply, also comprises
Pressure acquisition unit is used for gathering pressure signal; Temperature detecting unit is used for the collecting temperature signal;
Signal amplification unit is used for amplifying pressure signal and the temperature signal that collects;
The A/D converting unit, pressure signal and temperature signal after being used for amplifying are converted to digital signal;
Central processing unit (CPU) is used for control signal is processed and analyze and sent to the digital signal that obtains after the conversion;
Electric-motor drive unit is for controlling the startup of motor by control signal or closing;
The temperature regulation module is used for regulating temperature by control signal;
Unit is used for driving liquid crystal display panel by control unit;
Liquid crystal display panel is used for the work state information by the unit display device.
As preferably, comprise that also the human-computer dialogue unit comprises that power knob and information show and selects button, be used for artificial control apparatus startup, close, input liquid crystal display panel displaying contents, then operation control is more flexible.
As preferably, described pressure acquisition unit comprises two respectively pressure transducers of the pressure of collecting unit air compressor air storage tanks and relief opening.
As preferably, described temperature detecting unit comprises that two gather respectively the temperature transducer that oil temperature and motor in the circulatory system are arranged.
As preferably, also comprise LCD backlight, be used to liquid crystal display panel to provide backlight, also can observe the content that shows in the liquid crystal display panel in the situation that light is darker.
According to the technical solution of the utility model, adjust accurately, and observe very intuitively the working state of air compressor by liquid crystal digital display, and can observe the temperature of oil circulating system and prime mover in the equipment, thereby it is adjusted, reduce operator's potential safety hazard, reduced the rate of fault of equipment, improved the economic benefit of enterprise.
