and S4, judging whether the working temperature of the plunger structure is normal or not according to the outer surface temperature.
The working temperature monitoring method of the plunger structure is based on the plunger structure, when the fracturing pump drives the plunger structure to work, real-time detection is carried out through the temperature sensor 2 in the first groove 101, and specifically, temperature values in a plurality of working cycles are detected, because the temperature sensor 2 is positioned in the first groove 101, the detected temperature value and the outer surface temperature value of the plunger structure possibly have certain difference, on one hand, the working state of the plunger structure in the plurality of working cycles is evaluated according to the average value of the plurality of temperature values so as to avoid misjudgment, and on the other hand, the outer surface temperature of the plunger structure in the plurality of working cycles is determined according to the average value and the preset temperature coefficient, such as the product of the average value and the preset temperature so as to more accurately evaluate the outer surface temperature of the plunger structure, therefore, whether the working temperature of the plunger structure is normal or not is judged according to the outer surface temperature, so that the working temperature of the plunger structure can be monitored more reasonably.
The working temperature of the plunger structure can be judged to be abnormal when the temperature of the outer surface is higher than a certain preset temperature, and then an indication instruction for indicating the abnormality can be generated to the alarm device, if the indication instruction can be sent to the alarm device of the fracturing pump with the plunger structure, the alarm can be given out, and an operator can conveniently process the indication instruction in time.
In addition, the working temperature monitoring method of the plunger structure further comprises the following steps: and generating an indication instruction for displaying a plurality of temperature values and/or the outer surface temperature, and sending the indication instruction to a display device, such as the temperature display device of the fracturing pump with the plunger structure, so as to display the temperature values and/or the outer surface temperature values.
In an optional embodiment of the present invention, the monitoring method for the operating temperature of the plunger structure further includes determining an actual external surface temperature of the plunger structure in a plurality of the operating cycles according to the preset temperature coefficient and a plurality of the temperature values;
the judging whether the working state of the plunger structure is normal according to the outer surface temperature comprises:
and when the outer surface temperature is greater than or equal to a first preset temperature and a first preset number of actual outer surface temperatures greater than or equal to the first preset temperature exist, judging that the working temperature of the plunger structure is abnormal.
In this embodiment, judge according to the surface temperature whether the operating condition of plunger structure is normal, specifically pass through the surface temperature and the actual surface temperature in a plurality of duty cycles are judged, wherein the actual surface temperature is confirmed by presetting the temperature coefficient and the temperature value in each duty cycle, therefore, when the surface temperature is greater than first preset temperature, and when there is a first preset quantity in a plurality of actual surface temperatures and is greater than the numerical value of first preset temperature, show in a plurality of duty cycles, the surface temperature of plunger structure is all higher to this operating temperature of judging the plunger structure is unusual, therefore, the operating temperature monitoring to the plunger structure is reasonable more accurate.
In an optional embodiment, the determining whether the working state of the plunger structure is normal according to the temperature of the outer surface further includes:
when the outer surface temperature is greater than the second preset temperature and less than the first preset temperature, and the second preset number is greater than the third preset temperature, the working temperature of the plunger structure is judged to be abnormal when the real-time surface temperature exists, wherein the third preset temperature is greater than the first preset temperature, and the second preset number is less than the first preset number.
In this embodiment, if the outer surface temperature representing the average temperature is small, but in each working period, a second preset number of real-time surface temperatures exist, and when the temperature values of these real-time surface temperatures are large, it indicates that the plunger structure has a partial extreme working state, and at this time, it is determined that the working temperature of the plunger structure is abnormal, and the monitoring of the working temperature of the plunger structure is more reasonable and accurate.
