Description

Technical Field

[0001] The invention relates to the technical field of high-pressure cleaning devices, and in particular to a temperature-controlled multi-directionally adjustable high-pressure water jet cleaning device. Background Art

[0002] High-pressure water jet cleaning is a technology that uses a high-pressure pump to pressurize water to hundreds or even thousands of Pa, and then sprays high-speed water through a special nozzle. This technology uses the kinetic energy and impact force of the water flow to clean surface dirt, remove processing residues or coatings, and can achieve excellent cleaning results without the use of chemical cleaners. It is suitable for operations such as cleaning, cleaning, cutting, water injection drilling, spraying, crushing, grinding, etc. It has the characteristics of cleanliness, no heat effect, energy concentration, easy control, high efficiency, low cost, and safe operation, and is widely used in many industries.

[0003] At present, the common high-pressure water jet cleaning devices on the market are mostly similar in overall structure, mainly using high-pressure plunger pumps and spray guns. The high-pressure plunger pump pressurizes the tap water and sprays it horizontally through the spray gun.

[0004] However, there are some functional deficiencies in actual use and there is room for improvement. For example, when using a high-pressure water jet to clean dirt, tap water is usually directly connected to the spray, and there is basically no thermal effect. For stains and impurities that need to be heated to clean, there are still certain limitations in operation, and it does not have the function of heating operation. For example, when using a high-pressure water jet to clean dirt, the device usually surrounds the underwater pile foundation, and the high-pressure water jet is ejected horizontally through the nozzle. The spray angle and direction cannot be adjusted, the cleaning range is small, and when other dirt needs to be cleaned, the entire device needs to be moved, and the operation is not flexible enough.
