Abstract
The invention discloses a device for monitoring abrasive amount in a high-pressure tank online by utilizing ultrasonic, and belongs to the technical field of control. The device comprises a transmitting and receiving circuit module, a control circuit module and at least two ultrasonic sensors. A top cover is arranged at the upper end of the high-pressure abrasive tank, and is provided with a feeding end and a discharging end. The ultrasonic sensors are arranged at the axial positions on the outer sides of the high-pressure abrasive tank and are electrically connected with the transmitting and receiving circuit module. The transmitting and receiving circuit module is connected with the control circuit module electrically, and the control circuit module is connected with an industrial control computer electrically. The device has the advantages that the ultrasonic sensors generate stable ultrasonic to monitor the abrasive amount in the high-pressure abrasive tank in real time; and a monitor value is compared with a preset value by the control circuit module according to signals sent by the ultrasonic sensors, and automatic switch of a discharging system and a feeding system on high-pressure working state can be realized.
Description
Technical field
The present invention relates to a kind of on-Line Monitor Device, specifically is a kind of device that utilizes the interior amount of abrasive of pressure pan of ultrasound wave on-line monitoring sealing, belongs to the control technology field.
Background technology
At present, pre-mixed abrasive water jet numerically-controlled machine is following in working order, and just estimation or intuition are judged by rule of thumb in the control of amount of abrasive in its pressure pan.When filling, abrasive material only according to whether there being abrasive material to overflow simultaneously in the return pipe backwater, judges whether abrasive material has filled in the storage tank to put in place.Easy like this error, the influence cutting feed of causing.
Summary of the invention
Problem at above-mentioned prior art existence, the invention provides a kind of device that utilizes amount of abrasive in the ultrasound wave on-line monitoring pressure pan, produce stable ultrasound wave and monitor amount of abrasive in the pressure pan immediately exactly, simultaneously for discharge system and feeder system automatically conversion signal accurately is provided.
To achieve these goals, a kind of device that utilizes amount of abrasive in the ultrasound wave on-line monitoring pressure pan of the present invention, comprise emission and receiving circuit module, control circuit module and be no less than two ultrasonic sensors, in high-pressure abrasive material jar upper end top cover is set, top cover is provided with feeding end and discharge end, ultrasonic sensor is arranged on position vertically, the high-pressure abrasive material jar tank skin outside, ultrasonic sensor and emission are electrically connected with receiving circuit module, emission is electrically connected with receiving circuit module and control circuit module, and control circuit module and industrial computer are electrically connected.
Preferably, ultrasonic sensor mainly is made up of piezoelectric chip.
Preferably, the control circuit module is PLC.
Principle of work: send instruction by the control circuit module to emission and receiving circuit module, make its generation electric signal and change electric signal into ultrasonic signal by ultrasonic sensor, this ultrasonic signal is constantly to high-pressure abrasive material jar internal radiation.The ultrasound wave that ultrasonic sensor sends penetrates the outer wall of high-pressure abrasive material jar, behind the inwall that runs into the abrasive material tank skin, produce the first reflection ripple, received by ultrasonic sensor, if tested pilot is pure water, ultrasound wave continues to propagate forward, behind the inwall that runs into the tank body opposite, produce reflection wave for the second time, also can be received by ultrasonic sensor.If test point contains abrasive material, ultrasound wave can be sponged by abrasive material, so ultrasonic sensor can not receive signal.Ultrasonic sensor becomes the signal that receives into electric signal again and passes to emission and receiving circuit module simultaneously, through passing to the control circuit module again after the signal processing, by again result being shown at industrial computer after the control circuit resume module, just for discharge system and feeder system automatically conversion signal accurately is provided.
The invention has the beneficial effects as follows: ultrasonic sensor can produce stable ultrasound wave, constantly the amount of abrasive in the monitoring pressure pan; According to the signal that the ultrasonic sensor transmission comes, the control circuit module is compared monitor value with preset value, and when monitor value was lower than the minimum of the normal operation of equipment, industrial computer started feeder system; When monitor value was higher than the maximal value of the normal operation of equipment, industrial computer started discharge system, had realized that discharge system and feeder system are automatically changed under the high-pressure work state.
