Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flow rate pressure control measuring device for injecting a chemical solution used when performing a chemical solution injection method, and in particular, it improves the accuracy of data management in the chemical solution injection work and collects and stores data. The present invention relates to a flow rate pressure control measuring device for injecting a chemical liquid, which is intended to simplify the above.

[0002]

2. Description of the Related Art A flow rate pressure control measuring device for injecting a chemical solution which has been conventionally used sends a chart paper set on a pen writing recorder at a constant speed and displays the values of the injection flow rate and the injection pressure on the chart. I was recording. Therefore, when the integrated value of the injection flow rate is calculated, the value on the chart is read, and the recording length on the chart is measured and scaled. In addition, since the flow rate pressure control measuring device for injecting a chemical solution is provided with an integrating counter for displaying the total injecting amount in addition to the recorder, the value of the integrating counter is read as the integrated value of the injecting flow rate and displayed on the chart. And so on. And when verifying the injection flow rate,
The injection flow rate calculated from the data recorded on the chart was compared with the display value of the integration counter.

[0003]

However, the above-mentioned conventional flow rate pressure control measuring device for chemical liquid injection has the following problems to be solved. That is, since the chart paper set in the pen writing recorder has the characteristic of expanding and contracting under the influence of ambient humidity and temperature, the value on the chart is read and the recording length on the chart is changed. When measuring with a scale, accurate injection flow rate cannot be measured unless it is measured under the same ambient environment as when recording. In particular, because the influence of changes in humidity is large, a method is used in which a recorder such as a flow rate pressure control measuring device for chemical liquid injection is equipped with a drying device such as a heater to keep the humidity constant. It was very difficult to keep the humidity conditions constant.

Regarding the feed length of the chart paper,
In addition to the error due to the expansion and contraction of the chart paper itself, there was also a case where a feeding error occurred due to the backlash of the gear for feeding the chart paper. The delay in feeding the chart paper due to the backlash of the gear causes misalignment in the gear mesh due to an unreasonable force being applied to the gear when the chart paper is artificially pulled out to the front or when a comment is written on the chart paper. It occurs when it occurs. Even in such a case, the length of the recorded chart paper changes, so that the injection flow rate cannot be accurately measured by measuring the recording length on the chart.

Further, in the case of performing chemical solution injection work over a wide area, normally, the work area is divided into a plurality of injection holes and the chemical solution is injected sequentially, but in this case, when one injection hole is completed, However, the injection flow rate for each injection hole could not be accurately grasped unless the display value of the integration counter at that time was specified. If this process is not performed correctly, in addition to the error caused by the chart paper, the imbalance of the injection amount in each injection hole may occur due to inadequate data management due to the fact that there is no correspondence with the display value of the integration counter. It could not be detected.

Further, since the chart paper is not provided with the corresponding injection hole number, the recorder number used for the measurement, or the continuous number indicating the order of the chart paper, the flow rate pressure control measurement for other chemical liquid injection is performed. The chart paper may be confused with the chart paper by the device, the order of the chart paper may be unknown, and there is a drawback that the recorded data and the actual injection flow rate cannot be accurately verified.

The present invention has been proposed in order to solve the above-mentioned drawbacks of the prior art, and an object thereof is to print data relating to an integrated flow rate value on a chart every time injection is completed. An object of the present invention is to provide a highly accurate flow rate pressure control measuring device for injecting a chemical liquid that can be performed.

Furthermore, in the flow rate pressure management measuring device for chemical liquid injection according to claim 3, the recording means according to claim 1 or 2 assigns a serial number to each chart each time the injection operation is completed. It is characterized by being configured as follows.

[0011]

In the flow rate pressure control measuring device for injecting a chemical liquid of the present invention having the above configuration, when the injecting operation is started,
After the accumulated flow rate up to that time is reset, measurement is started, and when the injection operation is completed, the accumulated flow rate value, date, chart number, recorder number, etc. are automatically printed on the chart.

As a result, data management for each injection hole becomes accurate and easy. Further, unlike the conventional case, it is not necessary to consider the expansion and contraction of the chart paper, and the influence of the difference in the surrounding environment is reduced, so that the accuracy of the chemical liquid injection flow rate pressure control measuring device is improved.

Further, as shown in FIG. 1, the recording unit 1 is provided with a start / completion switch 5, an interruption switch 6 and a manual step switch 7, each of which operates as follows. That is, when the start / completion switch 5 is pressed, the previously recorded flow rate integrated value is set to "0", and the integration operation is newly started. When the start / completion switch 5 is pressed again, it is determined that the injection operation in one injection hole is completed, and the flow rate integrated value, date, chart number, recorder number, etc. are printed on the chart. In addition, the chart number is configured to be incremented by one each time the injection operation in each injection hole is completed, and the correspondence between each injection hole and each chart becomes clear.

In addition, the interruption switch 6 disconnects a predetermined rod or newly attaches another rod when the injection rod is pulled up or pushed down in order to sequentially change the injection position in the injection of each step. In order to perform the connecting work, it is necessary to temporarily suspend the injection work. In such a case, it is pressed, whereby the flow rate integration processing and chart feeding operation are stopped, and the pen is moved to the “0” position. , A rod disconnection or connection mark is printed on the chart. Furthermore, the manual step switch 7 is pressed when the injection pressure rises above the specified pressure or an abnormal phenomenon appears in the ground before the injection flow rate reaches the set value, whereby the injection operation is immediately performed.
