Description

Technical Field

[0001] This application belongs to the technical field of thermoplastic forming for pipeline repair, and particularly relates to a thermoplastic forming repair device with a water circulation system. Background Art

[0002] The thermoplastic forming repair method means that the lining pipe is pressed into a "C" shape, "H" shape or other shapes in the factory, coiled on a reel, and transported to the construction site. On-site or during transportation, special equipment is used to heat the lining pipe to make it soft, and it is placed into the original pipeline by pulling. Through pressurization and heating, the lining pipe is closely attached to the original pipeline, and after cooling, a hardened lining pipe is formed to complete the pipeline repair.

[0003] Due to the need for on-site heating operation of the lining pipe, the equipment used in the construction of the thermoplastic forming method, such as air compressors, steam boxes, steam generators, etc., are highly concentrated on professional work vehicles. The existing thermoplastic forming method generally uses a direct current cooling water system, also known as direct current water supply, which is a cooling water supply method that is not reused, that is, a once-through water system. In construction operations, when using equipment with a direct current cooling water system, the requirements for water sources and water quality cannot be met in a timely manner, and the direct current cooling water system is a once-through water system, so the reuse of water resources cannot be achieved. During the thermoplastic forming operation process (preheating, secondary heating, etc.), it is necessary to continuously generate water vapor with a steam generator to heat the lining pipe, inevitably consuming a large amount of water. And if the water quality does not meet the construction standards, it will also cause delays in the construction project. Therefore, a large amount of qualified water sources need to be prepared at the construction site to continuously replenish the water source of the steam generator, which not only increases the construction complexity but also wastes a large amount of water resources.

A variable frequency water supply pump 4 is provided on the water pipe connecting the steam generator water tank 5 and the steam generator 2, and the variable frequency water supply pump 4 pumps the water in the steam generator water tank 5 into the steam generator 2.

[0056] A steam sensor (not shown in the figure) is provided inside the steam generator 4 to monitor the density of the steam.

[0059] Since the thermoplastic molding repair device with a water circulation system is installed as a whole on a professional work vehicle, during operation, the professional work vehicle needs to be in a startup state all the time to power the device. At this time, the engine is running at idle speed, which will continuously generate automobile exhaust.
