Problems solved by technology
The traditional measurement of these parameters is to use a mechanical device to transmit the movement of the piston through the transmission mechanism, and to calculate these parameters indirectly through the encoder or sensor connected to the mechanical mechanism. The disadvantages are: 1. The mechanical transmission used for measurement The measurement error of the mechanism is relatively large; 2. Due to the existence of many moving and rotating parts, the maintenance amount is large and the failure rate is high; 3. The real-time performance is poor, especially the measurement of the moving speed of the gas cabinet piston is difficult

The invention relates to a measuring device for holder position, holder capacity and holder speed of a gas holder. The gas holder is internally provided with a gas holder piston, a maintenance platform is arranged at the top of the gas holder, the measuring device is arranged on the maintenance platform and comprises a sensor installed on the maintenance platform at the top of the gas holder, the sensor is connected with a controller through a cable, the controller is connected with an upper computer, the sensor is one of explosion-proof type high-power ultrasonic transducers or explosion-proof type radar level instruments, the controller comprises a controller shell and a display installed on the controller shell, and the controller shell is also internally provided with a single chip microcomputer and a control circuit which are used for conversion and control. The measuring device is simple in structure only by installing and connecting the sensor, the controller and the upper computer; the measuring device is unique in method, safe and reliable, high in real-time property, economical and practical as direct contact between the sensor and the gas holder piston does not exist and measured parameters can be displayed in real time; and the measuring device is flexible to control and high in maneuverability.
Description
technical field [0001] The invention belongs to the technical field of industrial measurement, and relates to a measuring device for gas cabinet position, cabinet capacity and cabinet speed. Background technique [0002] As one of the important production facilities of industrial enterprises, the gas cabinet plays an extremely important role in many aspects such as storage, scheduling of gas consumption, energy saving, and environmental protection. Therefore, the position of the gas cabinet, the capacity of the cabinet, and the moving speed of the piston of the gas cabinet (cabinet speed) are extremely important parameters in the production and operation of the gas cabinet. The traditional measurement of these parameters uses a mechanical device to transmit the movement of the piston through the transmission mechanism, and indirectly calculates these parameters through the encoder or sensor connected to the mechanical mechanism. The disadvantages are: 1. The mechanical trans...
