Abstract
The utility model discloses a temperature type air inlet control system of an air compressor. The system comprises a microprocessor, a human-computer interface, a motor, a loading valve and a pressure sensor. The human-computer interface is connected with the microprocessor, the pressure sensor is connected with the motor and the loading valve through the microprocessor separately, a draught fan and a temperature sensor are connected onto the microprocessor, the draught fan is connected with the temperature sensor through the microprocessor, and the motor is connected with the temperature sensor through the microprocessor. In most of the existing air inlet control systems of an air compressor, the pneumatic type pressure regulator control method is adopted, the temperature inside the air compressor is less than 70 DEG C, large amounts of water will be absorbed by the oil and the oil will be emulsified in this state for a long time, the emulsified oil has no bearing lubrication effect, and the bearing will be rusted due to the water in the emulsified oil, so major accidents will be caused by the reason that the air compressor seizure phenomenon is generated due to the bearing rust. By adopting the temperature type air inlet control system of the air compressor of the utility model, the above-mentioned problems are solved.
Description
Technical field
The utility model relates to a kind of air compressor assembly, relates in particular to a kind of temperature air intake control system of air compressor.
Background technique
What the air intake control system of existing air compressor adopted mostly is the control of pneumatic type pressure regulator; But this pneumatic type pressure regulator control system is only controlled air compressor loading air pressure and when air pressure reaches the numerical value of appointment, is just stopped to load; But so often the inside temperature of air compressor is lower than 70 degree at this moment; The pneumatics built-in temperature be lower than 70 often spend moisture can be comparatively sufficient, be in for a long time and can cause a large amount of moisture of oily emulsification absorption this state under, the oil of emulsification can lose the effect of lubricating bearings; Moisture in the oil emulsion makes bearing rust, and air compressor is killed because of bearing rust and caused a serious accident.
Chinese patent notification number CN201539395U; August 4 2010 day for announcing; A kind of air compressor air intake control system is disclosed; It is included in inductance pressure transducer, the time relay, solenoid valve and the easing valve that sets gradually on the admission line of cylinder, and inductance pressure transducer is connected with electromagnetic valve.The utility model has realized that air compressor main circuit when long-time idle running closes, thereby practices thrift unloaded consuming electric power, has avoided the shortcoming of unloaded power consumption.But so often the inside temperature of this air compressor is lower than 70 degree at this moment; The pneumatics built-in temperature be lower than 70 often spend moisture can be comparatively sufficient; Be in for a long time and can cause oily emulsification to absorb a large amount of moisture under this state; The oil of emulsification can lose the effect of lubricating bearings, and the moisture in the oil emulsion makes bearing rust, and air compressor is killed because of bearing rust and caused a serious accident.
The model utility content
The purpose of the utility model is to provide a kind of temperature air intake control system of air compressor; What solved that the air intake control system of existing air compressor mostly adopts is the control of pneumatic type pressure regulator; The inside temperature of air compressor is lower than 70 degree, is in for a long time to cause oily emulsification to absorb a large amount of moisture under this state, and the oil of emulsification can lose the effect of lubricating bearings; Moisture in the oil emulsion makes bearing rust, and air compressor is killed the problem that causes a serious accident because of bearing rust.
For solving the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of temperature air intake control system of air compressor; Comprise microprocessor, man-machine interface, motor, charge valve and pressure transducer; Man-machine interface connects microprocessor, and pressure transducer connects motor and charge valve respectively through microprocessor, is connected with blower fan and temperature transducer on the said microprocessor; Blower fan connects temperature transducer through microprocessor, and motor connects temperature transducer through microprocessor.Because the inside temperature of air compressor is lower than 70 degree, the time one is long, oil emulsification easily; Through increasing the temperature air intake control system, temperature is kept more than 70 degree, when the inside temperature of air compressor is lower than 70 degree; Temperature transducer feeds back to microprocessor, and microprocessor control motor continues operation, and is persistently overheating to more than 70 degree; Temperature is higher than 85 when spending, and temperature transducer feeds back to microprocessor, the heat radiation of microprocessor control control fan starting; Fall below 75 degree until temperature, guarantee that the oil in the air compressor is difficult for emulsification.
As preferably, be connected with time delay relay between said motor and microprocessor.It is accurate to guarantee between the motor time-delay.
As preferably, said microprocessor is a processor of single chip computer.Be convenient to the feedback of temperature transducer and pressure transducer is handled through processor of single chip computer.
The beneficial effect of the utility model is: the utility model has guaranteed that the oil in the air compressor is difficult for emulsification, makes the interior oil circuit operation of air compressor unobstructed, can not cause card machine accident.
Description of drawings
Fig. 1 is a kind of system architecture schematic representation of the utility model;
Embodiment
Pass through specific embodiment below, and combine accompanying drawing, the technological scheme of the utility model is done further to specifically describe:
Embodiment: shown in accompanying drawing 1; A kind of temperature air intake control system of air compressor; Comprise processor of single chip computer, man-machine interface, motor, charge valve and pressure transducer, man-machine interface connects processor of single chip computer, and pressure transducer connects motor and charge valve respectively through processor of single chip computer; Be connected with blower fan and temperature transducer on the processor of single chip computer; Blower fan connects temperature transducer through processor of single chip computer, and motor connects temperature transducer through processor of single chip computer, is connected with time delay relay between motor and processor of single chip computer.
The temperature air intake control system of this air compressor uses step following:
At first start the motor of air compressor, open charge valve and carry out the air inlet loading, pressure transducer fed back to processor of single chip computer after pressure reached setting value, and charge valve is closed in processor of single chip computer control; This moment, the temperature transducer feedback temperature was given processor of single chip computer, and temperature is lower than 70 when spending, motor time-delay idle running in 30 seconds; If temperature also is lower than 70 degree, motor continues time-delay idle running in 30 seconds, so repeatedly after temperature is higher than 70 degree; Motor is shut down, and time delay relay can not start in setting 60 seconds, when the air compressor inside temperature is higher than 85 when spending; Temperature transducer feeds back to processor of single chip computer, and the heat radiation of processor of single chip computer control control fan starting is fallen below 75 degree until temperature.
