Capsules is produced and is belonged to 24 hours continuous productions, and the pneumatic element using on hollow capsule production line is more, and air compressor is also in continuous running state.Air compressor for a long time operation there will be bearing stuck, and load strengthens and burns out motor, also there will be because dust is many, and radiation fan does not turn and causes heat radiation bad, and temperature raises and burns out motor.The fault of air compressor can cause the shutdown of hollow capsule production line, thereby causes Capsules to affect in market quality and efficiency.
Model utility content
Provide a kind of air compressor with self-protection function in order to address the above problem the utility model, running state that can Real-Time Monitoring air compressor, and automatically make respective handling, more safe and reliable.
The technical solution of the utility model is:
A kind of air compressor with self-protection function comprises air compressor body, described air compressor is provided with self-protection system, described self-protection system comprises hygrosensor, digital display ammeter, contactor, power supply, audible-visual annunciator, PLC controller, described digital display ammeter, PLC controller, the power supply of contactor and air compressor is in series by power line successively, described hygrosensor is arranged on the motor surface of air compressor, the input end of described hygrosensor contacts with the motor surface of air compressor, the output terminal of described hygrosensor is connected with the input end of described PLC controller, the output terminal of described PLC controller is also connected with described audible-visual annunciator.
Its working principle is:
The real-time running state of electric current and temperature when the self-protection system of this air compressor can detect compressor operation simultaneously.
(1) current detecting, the upper limit of current detecting is set as to 1.05 times of rated current in PLC controller, current conditions on digital display ammeter Real-Time Monitoring air compressor power circuit, and the current conditions detecting is passed to PLC controller, if electric current does not exceed the upper limit of setting, circuit normally moves, if air compressor is in continuous operation process, occur in the stuck even load increasing of bearing situation, the circuit increase that fails to be convened for lack of a quorum that powers on, electric current exceedes and exceeds the upper limit that PLC controller is set, now, current conditions is passed to PLC controller by digital display ammeter, PLC controller sends signal to the contactor in circuit, contactor is cut off the electricity supply, air compressor is quit work, simultaneously, PLC controller sends signal to audible-visual annunciator, make it send acoustooptic alarm, point out operator on duty to give in time site inspection, handling failure,
(2) temperature detection, the set temperature upper limit in PLC controller, the input end of hygrosensor detects the motor temperature of air compressor in real time, the output terminal of hygrosensor is passed to temperature conditions in PLC controller, if temperature does not exceed the upper limiting temperature of setting, PLC controller is not done instruction, air compressor normally moves, if in the process using continuously, air compressor radiation fan breaks down and quits work, or ambient dust gather cause air compressor motor temperature raise, when raising, temperature exceedes the upper limiting temperature of setting, signal is transmitted PLC controller by hygrosensor, thereby PLC controller control contactor, cut off the electricity supply, air compressor is quit work, simultaneously, PLC controller sends signal to audible-visual annunciator, make it send acoustooptic alarm, point out operator on duty to give in time site inspection, handling failure.
The utility model can Real-Time Monitoring air compressor running state, and the automatic intelligentized respective handling of making, can effectively avoid air compressor because of current overload or the too high irreversible damage causing of motor temperature, more safe and reliable, flexibility is high, the normal operation that ensured air compressor, has improved the quality of production and the manufacturing efficiency of Capsules to a certain extent, has reduced cost.
