Description
Technical field
The present invention relates to a kind of high pressure water cleaning self-rotating nozzle of preposition flow-guiding structure design, belong to industry cleaning link technology
Field, the product is mainly used in pipeline in high pressure water cleaning industry and scabbed and Fouling Cleaning.
Background technology
The industry development of Chinese industrial cleaning industry is started in the eighties in last century, far behind with last 100 yearses history
The developed country such as Europe, the United States, and initially or based on Chemical cleaning.With China's reform and opening-up and modernization construction paces
Quickening, and reinforcement of the compatriots to environmental protection consciousness, Cleaning by High Pressure Water Jet technique is by increasing institute of enterprise
Receive, main cause there are three aspects：(1) cleaning speed is fast, and (2) cleaning performance is good, and secondary dirt will not be produced after (3) cleaning
Dye.
Water under high pressure self-rotating nozzle is a kind of efficient, multiduty water jet cleaning instrument, is that cleaning equipment is standing.
The inventor of this product first is directed to high-pressure water cleaning device periphery accessory kit since 2002 and clear always
Instrument R＆D work is washed, during which once repeatedly coming to Europe, the United States etc. personally, international high-end producer carries out on-the-spot investigation and exchange of technology in the industry.With
Past water under high pressure spinning cleaning sprayer is essentially all to bear axially and radially load by bearing, in practical application mistake
Had the following disadvantages in journey：(1) outside dimension is larger, it is impossible to meet requirement of the cleaning compared with small-bore tubing road；(2) because it is in structure
Bearing is selected in design, so must also have sealing and the sealing of dust reduction capability for design bearing, in water under high pressure and dirt
Under particle and the bad working environments environment deposited, seal durability is very short, seals once damage, internal bearings are damaged therewith.
Before this product exploitation, the first inventor and its R＆D team have lasted the time more than 4 years, successfully have developed a small
Type water under high pressure self-rotating nozzle, and successfully applied for the national inventing patent (patent No.：ZL 201410328296X).The product
Although having filled up domestic blank, customer using cost is reduced, the dependence to external similar products is reduced, it is processed
Required precision is high, and manufacture difficulty is very large, and it is difficult to be greatly reduced to cause production cost.
The content of the invention
The present invention seeks to by more science, reasonably change self-rotating nozzle internal structure design, further reduction
Difficulty is fabricated, so as to greatly improve product yield, reduction production and use cost so that the product in the field of business can be obtained
It is widely popularized, uses, so as to is national energy-saving emission reduction, be enterprise abridged edition consumption reduction and make positive contribution.
