Port is connect with water tank, and the water inlet port connection of the water outlet port booster pump of water pump, the water outlet port of the booster pump passes through pipe
Road is connected with giant, and the high-pressure spray gun includes nozzle, is fixed with a limiter with clip in the spray nozzle front end.
Wherein, the height of the limiter is greater than 200mm.
Wherein, the gun head uses boron nitride material.
The method to be derusted using above-mentioned apparatus anti-corrosion, comprising the following steps:
(1) high-pressure spray gun, water pump, booster pump are connected；
(2) booster pump is pressurized to 30MPa, gets out fine sand, sucked in the negative pressure that high-pressure spray gun front end is formed by water flow
Spray gun forms water sand and sprays；
(3) with high-energy water sand jet impulse, wear down the metal surface removed, corrosion layer, the layer of scale of metal surface
Etc. multidigits stratiform be in porous distribution, once layer of scale is saturated, high pressure water sand jet stream is just at chock shape insertion layer of scale and metal
Between base material, when its impact energy is greater than the limit of adhesion intensity of layer of scale and base material, corrosion, layer of scale are just removed.
The beneficial effects of the present invention are: the present invention has a wide range of application, and high-pressure wash spray head is compact and flexible, either manages
Road, container intracavity, hard foulant or tamper, the place that all high-pressure water jets can be mapped to can thoroughly be cleaned
Completely, and to equipment material, characteristic and dirt type without particular/special requirement.
The safe adaptability of high-pressure water jet is good, can be applied in combustible and explosive area, and therefore, high-pressure water jet exists
Application in petroleum and petrochemical industry seems very prominent.
Water under high pressure jet stream rust cleaning security performance is high, to operator without actual bodily harm.In descaling process to periphery crowd without
Any life influences.
It can construct in dense population, using tap water as working media, this medium is tasteless, nontoxic, nothing
It is smelly, after the high-pressure water jet atomization of ejection, it can also reduce the air-borne dust concentration of operation area.
Atmospheric dust is set to be reduced to the 2mg/m of national regulation3Hereinafter, being conducive to eliminate silicosis pathogeny and to environment without dirt
Dye.
Detailed description of the invention
Technical solution in order to illustrate the embodiments of the present invention more clearly, below will be to needed in embodiment description
Attached drawing is briefly described, it should be apparent that, the accompanying drawings in the following description is only the present invention in order to illustrate more clearly of this hair
Bright embodiment or technical solution in the prior art, below will be p- required for describing the embodiments or the prior art attached
Figure is briefly described, for those of ordinary skill in the art, without creative efforts, can be with root
Other attached drawings are obtained according to these attached drawings.
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
A kind of high-pressure spray gun derusting device as shown in Figure 1, including high-pressure spray gun, water pump, booster pump, the water pump into
Water end (W.E.) mouth is connect with water source, and the water outlet port of water pump and the water inlet port of booster pump connect, the water inlet port of high-pressure spray gun and increasing
The water outlet port of press pump connects, and the high-pressure spray gun includes pipette tips, holding rod, nozzle, is fixed in the pipette tips front end with clip
One limiter.
The method to be derusted using above-mentioned apparatus anti-corrosion, comprising the following steps:
(1) high-pressure spray gun, water pump, booster pump are connected；
(2) booster pump is pressurized to 30MPa, gets out fine sand, sucked in the negative pressure that high-pressure spray gun front end is formed by water flow
Spray gun forms water sand and sprays；
(3) with high-energy water sand jet impulse, wear down the metal surface removed, corrosion layer, the layer of scale of metal surface
Etc. multidigits stratiform be in porous distribution, once layer of scale is saturated, high pressure water sand jet stream is just at chock shape insertion layer of scale and metal
Between base material, when its impact energy is greater than the limit of adhesion intensity of layer of scale and base material, corrosion, layer of scale are just removed.
Without damage to LNG storage tank base material to guarantee in the case where high-pressure spray gun derusting, site requirement is used before pipette tips
Clip fixes a limiter, it is ensured that nozzle distance reservoir surface 200mm or more, and can protect nozzle.
Make spray gun parital vacuum using high-velocity flow, thus generation suction is drawn onto fine sand after being combined in spray gun and passes through
20Mpa pressure above sprays, to generate great hitting power, reaches derusting effect, abrasive material uses river sand or sea sand.It removes
Speed of becoming rusty is up to 30m2/h or more, and surface of derusting is up to 2.5 grades.Gun head uses boron nitride material, is most hard artificial material
One of, microhardness is up to 17800Mpa, its main feature is that extremely hard wear-resisting, with soda acid Fails To Respond, high-low temperature resistant high pressure works the longevity
Life was up to 1,000 hours or more.
Anti-corrosion derusting is safely and effectively carried out to LNG storage tank, derusting grade has reached Sa2.5 grades and effectively protected
The safe and stable operation of LNG storage tank.The derusting grade of site inspection metal surface reaches Sa2.5 grades, and reservoir surface appearance reaches
It thoroughly derusts very much, steel surface is without attachments such as visible grease, dirt, oxide skin, iron rust and painting layer and any
Remaining trace should be only the standard of dotted or strip slight color spot.
Motor, water pump, booster pump, water tank, fine sand case can be combined on a trolley, staff is facilitated to move back and forth,
It is time saving and energy saving.
