Description
Technical field
The present invention relates to a kind of saturated vapour washing unit and cleaning method thereof, relate in particular to the turbidity test in the diesel fuel system.
Background technique
Because the turbidity test in the raising day by day that diesel emission requires, oil-burning machine oil-fired system require to have had the standard of intimate harshness.And because the improving constantly of diesel fuel system jet pressure, the nozzle opening that plays the injector nozzle matching parts of diesel oil atomization effect also is reduced to the 0.2-0.23mm of P type by the 0.28-0.35mm of S type.At present will further be reduced to 0.15mm for the nozzle opening that satisfies injector nozzle matching parts in state the discharges use 3 or more fuel oil high-pressure common-rail injection system.After the miniaturization of spray orifice, the atomizing particle of diesel oil is more tiny, and penetrability is stronger, and diesel oil can better fully be burnt, and has reduced the discharging of nitride and particulate matter, but intrasystem turbidity test have also been proposed more harsh requirement.According to oil sprayer JB/T7661-2004 " jerk pump oil nozzle cleanliness limit "; The metal granule of high-pressure oil duct is not more than 0.5mm; The metal granule of overgauge can stop up spray orifice or damage even part sealing surface; Influence oil sprayer atomized diesel fuel function, and then cause bad working environments such as diesel engine power decline, particulate matter exceed standard.
Existing conventional main mode of cleaning is liquid wash and ultrasonic cleaning.Liquid cleans can use diesel oil, gasoline or water-soluble washing agent etc., but removes the impurity difficulty in the liquid in actual the cleaning.That filters even have ready conditions also has in the liquid pressurization pollution from suction booster or other pipeline.In the oil pump nozzle industry, it is quite general that gasoline cleans, and the effect of using gasoline to clean is better, but also have problem such as filtration difficulty, and gasoline volatilizees easily, is inflammable explosive article, preserves and use dangerous; There is a filtration difficult problem equally in ultrasonic cleaning, and pollutes each other easily.More than two kinds of cleaning methods also have a common shortcoming, little at the flow velocity that cleans the position, cleaning performance is unstable.Use pressurized air directly to clean, certain effect is arranged, but compressed-air actuated pressure, in the severe operational environment in winter and because temperature is low, and the washing agent viscosity of inter process is big, can be attached to hole wall with impurity and be difficult for removing at 0.5-0.7Mpa.
Summary of the invention
The present invention is directed to the deficiency of existing technology, provide a kind of pollution little, saturated vapour washing unit and cleaning method thereof that turbidity test are high.
The present invention realizes through following technological scheme:
A kind of saturated vapour washing unit is characterized in that: said saturated vapour washing unit comprises support, and steam generation control gear and water supply filtrating equipment are set on support; Said steam generation control gear comprises steam generator; The electromagnetic contact pressure control table of pilot pressure upper and lower is set on steam generator; The temperature controlling instrument and the service pipe of control temperature upper and lower are provided with the working electromagnet valve in the middle of service pipe, at an end of service pipe spray gun is set.
Said saturated vapour washing unit is characterized in that: said saturated vapour generation control gear also comprises the pressure-limit valve that prevents that equipment decompression is not smooth.

A kind of saturated vapour cleaning method is characterized in that: water is heated formation temperature reach more than 150 ℃ in steam generator, pressure is greater than the HTHP saturated vapour of 10Bar; Through spray gun the steam of HTHP is passed and to be cleaned workpiece surface.
Compared with prior art, beneficial effect of the present invention is:
This cleaning is simple and convenient, because steam directly enters air after using, does not have the recovery filtration problem, also just can not pollute the problem of workpiece owing to cleaning solution once more.The pressure of steam in generator is greater than 10Bar; Supply gas pressure greater than the normal air compressor; And in the generator temperature greater than 150 ℃, export temperature greater than 80 ℃; So not only can cleaning and removing remove the impurity particle in the elongated orifices when cleaning, various cutting fluids that also can the original work in-process of workpiece is residual, greasy dirt are removed.
Compare petroleum-type and clean, the pollution that saturated vapour cleans is few, has only water vapor to discharge, and does not consume oil plant, is beneficial to environmental protection; Compare ultrasonic cleaning, the water resources of consumption significantly reduces, and ultrasonic cleaning needs big water gaging and water-soluble washing agent, runs off and the frequent cleaning solution of changing because workpiece carries, and consume water resources is bigger.Existing this equipment is mainly used in the cleaning that supplies use for diesel engine injector assembly body; Can meet and exceed the requirement of JB/T7661-2004 " jerk pump oil nozzle cleanliness limit " after the cleaning fully to impurity particle; Particle length is less than 0.2mm in 80% batch sampling observation, all the other 20% batch in particle less than 0.3mm.
