Technical Field

[0001] The utility model belongs to the field of coal bed gas well head pressure monitoring devices, in particular to a coal bed gas well head pressure monitoring device. Background Art

[0002] The coalbed methane wellhead pressure monitoring device is a device used to monitor the coalbed methane wellhead pressure. It is usually composed of a pressure sensor, a data acquisition system, a data processing system, and a display system. The coalbed methane wellhead pressure refers to the pressure at the wellhead during the coalbed methane mining process. Monitoring the coalbed methane wellhead pressure can help miners understand the production of coalbed methane wells, detect abnormal wellhead pressure in time, and ensure the safe operation of coalbed methane wells. The coalbed methane wellhead pressure monitoring device senses the wellhead pressure in real time through the pressure sensor and transmits the collected data to the data acquisition system. The data acquisition system processes the collected data and transmits it to the data processing system. The data processing system analyzes and calculates the collected data to obtain the change trend and abnormal situation of the coalbed methane wellhead pressure. Finally, the display system displays the processed data to the user in the form of graphics or numbers. The coalbed methane wellhead pressure monitoring device can help miners understand the coalbed methane wellhead pressure in real time, detect abnormal wellhead pressure in time, take corresponding measures to adjust and process, and ensure the safe production of coalbed methane wells. At the same time, it can also provide storage and analysis of historical data, and provide a reference basis for decision-making in coalbed methane mining. In short, the coalbed methane wellhead pressure monitoring device is an important equipment in the coalbed methane mining process. It helps miners understand the production situation of coalbed methane wells by real-time monitoring of wellhead pressure, and ensures the safe operation of coalbed methane wells.
