Problems solved by technology

[0004] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a pipe scale cleaning skid, which solves the shortcomings of the existing physical cleaning technology: cleaning and descaling are not thorough, and the cleaner is easily blocked In the pipeline, when cutting the pipeline, it will inevitably cause many disadvantages such as environmental pollution and low work efficiency by the liquid leaking and flowing out of the pipeline. A special vehicle-mounted integrated vehicle with guaranteed standardization, high intelligent efficiency, anti-jamming, clean and environmental protection is proposed. cleaning tool skid

Embodiment 1

[0026] refer to Figure 7 , the ball-reed 22 of the ball-12 cleaning ball is in cavitation phenomenon, the ball-12 is a bowl-shaped cleaning ball head, multi-layer ball-reed 22 and rubber lining, multi-piece, staggered, stacked arrangement, for Choose different R cleaning ball heads for pipes with different diameters. Under the action of high-pressure water on the cleaning ball head, the pressure head makes the rubber lining stick to the reed, and the reed is stretched to obtain a larger R (approximately equal to the inner diameter of the pipe); the interleaved reed and lining make the high-pressure water discharge The surface is very small, and a huge pressure difference is formed between the front and back of the ball head. The high-pressure water flow rushes toward the front of the cleaning ball device along the tiny gap, and a large number of high-speed air bubbles and swirl flow are generated at the front end, and cavitation is formed locally on the pipe wall. High-frequ...

Embodiment 2

[0029] The interactive force between ball three 25 and ball two 24 produces rotary cutting.

[0030]When the pipeline is slightly or moderately fouled, the thickness of the scale is not enough to make the ball 24 be "stuck". Since the rigidity of the reed of the ball 24 cutter head and the spring force of the supporting and retracting mechanism are stronger than the ball 3, so The bonding force between the ball 2 cutter head reed and the inner wall of the pipe is stronger than that of the ball 3 25 cutter head reed and the inner wall of the pipe, resulting in the friction force of the ball 2 24 cutter head reed acting on the scale on the pipe wall is stronger than that of the ball 3 Cutter head reed acts on the frictional force (resistance when ball two 24 advances is greater than ball three 25) on the tube wall scale. Therefore, when the pulse flow acts on ball one 12, the compressed distance between ball one 12 and ball two 24 becomes shorter; the distance between ball three...

Embodiment 3

[0039] refer to image 3 , Figure 4 , Figure 5 and Figure 6 The rigidity of the reed on the ball 2 and the elastic force of the inner spring of the retracting mechanism are stronger than that of the ball 3. It is most likely to be stuck when the inner wall of the pipe is seriously fouled. When the ball 24 is stuck, the ball 24 can be used as a A fixed fulcrum drives ball three 25 to rotate and displace when ball one 12 pushes forward, and reciprocates multiple times to rotate and scrape the scale layer of ball two 24 front end pipes. After many times of rotating and scraping, it is still impossible to make the ball two 24 pass through the pipeline blockage, then increase the output of the pump, so that the pressure acting on the ball one 12 continues to increase. When the pressure value is greater than the spring compression force in the retracting mechanism, The inner spring of the retracting mechanism continues to be compressed, and the keel of the retracting mechanism...

Abstract

The invention discloses a pipeline scale cleaning sledge, and relates to the technical field of cleaning equipment. The sledge comprises a spiral shaft, a first ball, a second ball and a third ball, a first locking nut and a second locking nut are mounted at two ends of the spiral shaft respectively, the third ball and the first ball are arranged at the first locking nut and the second locking nut respectively, the outer wall of the middle of the spiral shaft is sleeved with a third casing pipe, the second ball is fixedly arranged at one end, located at the third ball, of the third casing pipe, the outer wall of the third casing pipe is sleeved with a second casing pipe, the third casing pipe is in limiting connection with the second casing pipe, the outer wall of the second casing pipe is sleeved with a first casing pipe, the first casing pipe is in limiting connection with the second casing pipe, and one end of the first casing pipe is fixedly connected with the first ball; a coaxial transmission is arranged between the third ball and the second ball and is fixed to the spiral shaft. According to the pipeline scale cleaning sledge, the defects of an existing physical cleaning technology are overcome, the problem that special cleaning equipment with standard configuration is lacked is solved, an integrated vehicle-mounted special tool sledge which is standardized, guaranteed, high in electrification efficiency, anti-jamming, clean and environment-friendly is provided, and the sledge has the value of deep application and wide popularization.

Description

Technical field: [0001] The invention relates to the technical field of cleaning equipment, in particular to a pipeline scale cleaning skid. Background technique: [0002] In oilfield oil and gas drilling, gathering and transportation projects, various production fluids, injection fluids, oil, gas and water gathering and transportation are all transported by pipelines. A liquid in which various components are mixed together, some of which form colloidal, hard, layered deposits (sediments) on the pipe walls. With the large-scale popularization and application of polymer flooding, tertiary recovery technology and biological flooding technology, these scales are common in the inner wall of the pipeline, and the safety of pipeline operation and the benefits of transportation efficiency are greatly restricted. Therefore, pipeline cleaning technology is one of the essential key technologies in oil and gas engineering. [0003] At present, there are two main technical methods for...
