Today, I will introduce a national invention authorized patent-an oil pipeline flowmeter. The patent was applied for by Shaanxi Jieming New Energy Engineering Co., Ltd., and the authorization was announced on January 25, 2017.
Content descriptionThe utility model relates to a flow meter, in particular to a petroleum pipeline flow meter.
Background of the inventionWith the rapid development of the petroleum industry, the development and production management of oil fields has gradually developed towards intelligent management, which has been widely promoted and applied. Downhole flow control technology is an indispensable part of oilfield technology. In the prior art, when measuring oil pipeline flow, a flow sensor is usually installed directly in the oil pipeline, and the flow sensor is used to detect the flow rate of oil in the pipeline in real time, and then The received flow rate information is sent to the controller, so that the controller displays the received flow rate information on the display. However, the above-mentioned oil pipeline flow measurement method is only applicable to scenarios where the pipeline is full of oil, and the application range is narrow.
Summary of the inventionThe utility model provides an oil pipeline flowmeter, which can reduce the failure of the oil pump due to excessive oil flow, prolong the life of the oil pump, and provide convenient conditions for the staff to calculate the oil flow in the pipeline.
The present utility model solves the above-mentioned problems through the following technical means: a petroleum pipeline flow meter of the present utility model includes: a casing, a rotating shaft arranged in the casing, and a control device arranged outside the casing, on the rotating shaft There are several blades, one end of the shell is provided with a first thread for connecting with the oil inlet pipe, and the other end of the shell is respectively provided with a second thread for connecting with the first oil outlet pipe and The third thread connected to the second oil outlet pipeline, the blade is provided with a speed sensor, the first oil outlet pipeline is provided with a solenoid valve, and the oil inlet of the oil inlet pipeline is connected to an oil pump; the control The device includes a microcontroller, a first drive circuit, a second drive circuit, a liquid crystal display module, and a voice alarm module. The speed sensor is connected to the input end of the microcontroller. The first drive circuit and the second drive circuit , The liquid crystal display module and the voice alarm module are both connected with the output terminal of the microcontroller, the output terminal of the first drive circuit is connected with the solenoid valve, and the output terminal of the second drive circuit is connected with the oil pump.
Further, the first thread, the second thread and the third thread are all provided with a sealing element. The control device also includes a wireless communication module, and the wireless communication module is connected to the input and output terminals of the microcontroller. A waterproof material is arranged in the shell. The blades are evenly arranged on the rotating shaft.
An oil pipeline flowmeter of the utility model has the following beneficial effects: The utility model provides a petroleum pipeline flowmeter. When the worker starts the oil pump, the oil enters the oil inlet pipeline under the action of the oil pump, and then enters the shell. Because the oil is in a flowing state, the blades rotate with the flow of the oil, so that the speed sensor installed on the blade can detect the speed of the blade rotation, and send the detected speed of the blade rotation to the microcontroller, and the micro-controller When the receiver determines that the received speed value is less than the preset value, the solenoid valve is controlled to close, and the oil only flows out of the second oil outlet pipe; when it is determined that the received speed value is greater than the preset value, the solenoid is controlled by the first drive circuit The valve is opened, so that the oil flows out from the first oil outlet pipeline and the second oil outlet pipeline at the same time, which can reduce the failure of the oil pump due to excessive oil flow; when it is determined that the received speed value is zero, the voice alarm module will give an alarm , And control the oil pump to stop working through the second drive circuit to prevent the oil pump from idling and prolong the life of the oil pump. In addition, the microcontroller can also display the received speed value through the liquid crystal display module to facilitate the staff according to the speed value and blade The corresponding relationship between the rotation speed and the oil flow rate determines the oil flow rate in the oil pipeline, and then determines the oil flow rate according to the oil flow rate, which provides convenient conditions for the staff to follow-up work.
In summary, the oil pipeline flowmeter of the present invention can reduce the failure of the oil pump due to excessive oil flow, prolong the life of the oil pump, and provide convenient conditions for the staff to calculate the oil flow in the pipeline.
