Description
Technical Field

The air compressor is a technology for compressing air by using electric energy or mechanical energy to obtain air with a certain pressure. In electrical power systems, air compressors are very widely used, and the use of air compressors is not available in any form of power station. According to the different power generation types, the air consumption amount is different, and the quality of the compressed air is also different. The compressed air of the thermal power plant is mainly used for an instrument compressed air system, a plant impurity compressed air system, a water treatment air compression system and an ash removal air compression system. The compressed air of the hydropower station is mainly used for a compressed air system for instruments, a mixed air compression system in a factory building and an air compression system for equipment power. Compared with a thermal power station, the air compression system of the nuclear power station lacks the application of an ash removal system.
In power systems, compressed air leakage is one of the largest wastage of power plants. Compressed air leakage results in the plant needing to use more power. Meanwhile, leakage of compressed air can lead to system pressure reduction, so that an actuating mechanism is slow or refused to act, the functional efficiency of pneumatic equipment is reduced, the service life of the equipment is shortened, the maintenance cost and the unplanned shutdown period are increased, and finally the production efficiency of a factory is reduced and the production cost is increased.

When the invention is used for detecting the air leakage of the medium-low pressure air compressor, the specific detection process is as follows:
the power module then supplies power to each module by pressing an automatic detection button on the control panel. The singlechip controls the first motor to rotate, and the sliding module starts to run on the track of the roof. When the photoelectric sensor on the sliding block senses light emitted by the light source on the guide rail, the sensor feeds signals back to the singlechip, and the singlechip controls the sliding block to stop. After the sliding block stops, the singlechip controls the first telescopic device to gradually extend, and in the extending process, the color sensor on the detection module detects the color code near the pipeline valve. According to the different colors of the color codes, the detection module can perform different actions:
(1) When detecting independent vertical pipeline, the color sensor detects the nearby red color code of valve, and the sensor feeds back the signal to the singlechip, and the singlechip controls the first telescoping device to stop the extension. At this time, the ultrasonic detector in the single chip microcomputer control detection module detects the air leakage condition at the valve. Meanwhile, the singlechip controls the horizontal angle conversion device to enable the ultrasonic sensor to do circular arc motion of about 180 degrees around the valve to detect the periphery of the valve. After the detection is finished, the detection result is displayed in the man-machine interaction module through the singlechip. Then, the detection module stops working, the angle conversion device and the telescopic device return to the original states, and the sliding block on the roof is restarted to move forwards along the track;
(2) When detecting independent horizontal pipeline, the colour sensor detects the yellow color code on the pipeline earlier, and the sensor gives the singlechip with signal feedback, and singlechip control first telescoping device stops the extension, and control vertical angle transform module is rotatory 90 degrees with second telescoping device and horizontal pipeline are parallel, later singlechip control second telescoping device extends, when detecting the nearby red color code of valve, and second telescoping device stops the extension, and horizontal angle transform module and detection module operation carry out gas leakage detection. After the detection is finished, the man-machine interaction module displays the result, and the telescopic device, the angle conversion device and the detection device are restored to the initial state;
(3) When detecting horizontal and vertical pipeline that connects, the color sensor can detect the blue color code of vertical pipeline valve department first, and first elongation device stops, and horizontal angle conversion device and detection device operation begin to carry out valve department gas leakage detection. After the detection is finished, the man-machine interaction module displays the result, the horizontal angle conversion device and the detection device recover to an initial state, the first telescopic device continues to stretch, when the color sensor detects a yellow sensor at the joint of the horizontal and vertical pipelines, the first telescopic device stops, the vertical angle conversion device operates to rotate the second telescopic device by 90 degrees, then the second telescopic device gradually stretches, after the detection device detects a red sensor near the valve of the horizontal pipeline, the second telescopic device stops, and the detection device and the horizontal angle conversion device operate to detect air leakage at the valve. After the inspection is finished, the display device displays the result, and the first telescopic device, the second telescopic device, the horizontal angle conversion device, the vertical angle conversion device and the detection device are all restored to the initial state, and the sliding block on the roof fixing frame continues to move forwards.
After all pipeline valves are detected, the single chip microcomputer controls the sliding blocks on the track to return to the original positions. The power module stops supplying power to the other modules. And (5) ending the whole set of operation.
When the valve on a certain pipeline is to be detected in a gas leakage way manually, a manual operation button on a control panel is clicked, then the control button below the control panel can be used for manually controlling the movement of a sliding block on a roof rail, when the control button is moved to a designated position, a detection button is pressed, a detection device can automatically detect the pipeline valve at the position, after the detection is finished, the device below the sliding block is restored to an initial state, then the sliding block can be manually controlled to move to the next position or the end button is clicked, the whole device is restored to the initial position, and the detection is ended.
