Description
Technical Field
The invention relates to the technical field related to flow test. More particularly, the invention relates to an auxiliary device for testing the flow of a pipeline and a using method thereof.
Background
When various industrial and mining enterprises carry out water balance test work, flow tests need to be carried out on various water conveying pipelines on a production site, and a portable ultrasonic flow meter is often used as a test instrument. During testing, a straight pipe section needs to be selected from a pipeline to be tested, two probes are arranged on the outer wall of the pipeline, and the flow velocity of liquid in the pipeline is measured by transmitting and receiving ultrasonic signals between the probes. The test method comprises an even sound path method and an odd sound path method, wherein the even sound path method means that ultrasonic signals transmitted and received between two probes need to undergo even sound paths, namely the two probes need to be arranged on the same straight line on the outer wall of the pipeline, and the straight line is parallel to the axial lead of the pipeline; the odd-numbered sound path method means that ultrasonic signals transmitted and received between two probes need to undergo odd-numbered sound paths, namely the two probes need to be respectively arranged on two opposite straight lines on the outer wall of the pipeline, and the two straight lines are in an axisymmetric state relative to the axial lead of the pipeline. The larger the number of acoustic paths selected by the test method is, the longer the transmission distance of the ultrasonic signal is, the longer the setting distance between the two probes is, and the longer the length of the straight pipe section required by the test is. In addition, as the transmission distance increases, the signal intensity of the ultrasonic wave gradually attenuates.
In practical application, a two-sound-path method is usually selected to carry out test work, because the two-sound-path method belongs to an even-number sound-path method, the position of one straight line on the outer wall of the pipeline is only required to be determined during test, and the operation is relatively simple. In the even number sound path method type, the two-sound path method is the method with the shortest transmission distance of the ultrasonic signals, and the problem of signal attenuation caused by long-distance transmission of the ultrasonic signals can be avoided to the greatest extent. However, in some special test environments, only one of the odd-numbered acoustic path methods can be used for testing, and if the pipeline arrangement space in a test site is narrow, the length of the straight pipe section for testing is too short, and the acoustic path number can only be reduced to shorten the probe distance, so that two probes can be arranged on the short straight pipe section for testing at the same time. If the fluid in the pipeline is impure and is mixed with suspended matters or bubbles, the ultrasonic signal can be tested only by using a method with the minimum transmission distance under the condition of serious attenuation of the ultrasonic signal, so that the adverse effect of the signal attenuation on the test is reduced as much as possible.
The method for determining the position of a straight line comprises the following steps of: 1. measurements are taken around the circumference of the pipe using a tape measure. 2. And calculating the measurement result, and determining a group of two scale positions which are symmetrical about the axis of the pipeline. 3. At two graduated positions, a straight line is visually estimated by the operator and drawn with a straight ruler. The reference straight line is determined in such a way, so that the operation is complicated, errors are easy to occur, and the testing precision is influenced. Therefore, it is desirable to design a technical solution that can overcome the above-mentioned drawbacks.
