一、超声波洗井的原理介绍超声波清洗技术已在我国一些工业生产中得到应用,那末超声波原理能否应用于清洗结垢的生产井呢?为此,我们进行了试验。超声波清洗的机械原理可归结为:超声波的“空化作用”,即超声波在液体中传播时,由于交变声压的作用,产生了无数的微气泡,正是由于这些无数的微气泡,进行着连续不断的闭合作用运动,在这个过程中产生了一个离心的、数量级可达几千个大气压的冲击波,这种强烈的冲击作用足以使附着于金属表面的固体物爆裂而散开,这就是超声波清洗的基本原理。这种方法的主要优点是,由于超声波在液体中产生的压力是均匀的,所以对管井井壁、滤网无破坏作用(后面的试验结果将会看到),这就解决了其他清洗方法存在的问题。因而,它是一种比较理想的方法。
First, the principle of ultrasonic washing wells Ultrasonic cleaning technology has been applied in some of our industrial production, then the ultrasonic principle can be used to clean the scale production wells? For this, we conducted the test. The mechanical principle of ultrasonic cleaning can be attributed to: the “cavitation effect” of ultrasonic waves, that is, when ultrasonic waves propagate in liquids, numerous micro-bubbles are produced due to the effects of alternating sound pressure, and it is precisely because of these numerous micro-bubbles that With a continuous, closed-action movement, a centrifugal shock wave with an order of magnitude of several thousand atmospheres is generated in this process. This strong impact is enough to burst the solid material adhering to the metal surface and spread out. The basic principle of ultrasonic cleaning. The main advantage of this method is that since the pressure generated by the ultrasonic waves in the liquid is uniform, there is no destructive effect on the borehole shaft wall and the filter screen (the test results will be seen later), which solves the existence of other cleaning methods. The problem. Therefore, it is a more ideal method.
