Description
Technical field
The present invention relates to a kind of cleaning method of railway rolling stock brake pipe, particularly relate to a kind of method of cleaning the brake pipe inwall with high-pressure spray.
Background technology
The brakes of rail vehicles is the vitals of the normal operation of rolling stock.In service as foreign matter in brakes, occurs and will in system, move at rolling stock along with intrasystem pressure air, in moving in case stop up in the air admission hole of brake valve or the system other air ducts will cause train to start or train braking malfunctioning, cause catastrophic consequence.The brakes of rail vehicles need contain a large amount of dusts and moisture and form mixture through inflation and venting many times in long-term running in the inhaled air, be deposited in the brakes.The rolling stock brake pipe is the straight shape steel pipe of diameter 60mm, and because of vehicle different braking length of tube does not wait, no longer than 4m, two ends are with screw thread.At present, in the maintenance process of rolling stock, need to disintegrate, but cleanings such as high-pressure blast purging are only carried out in the inside of the brake pipe of rolling stock, can't thoroughly remove being deposited on deposit in the pipe etc. to brakes.Deposit came off and probably along with pressure air moves when train was in operation situations such as running into vibration or outside strike.Therefore in the maintenance process of rolling stock, need components interior such as brake pipe are thoroughly cleaned, the deposit of brake pipe inwall deposition is cleaned out, guarantee the security of operation of train.
The content of invention
Purpose of the present invention is exactly in order to overcome the deficiency of above-mentioned technology, to provide a kind of and can thoroughly remove the interior deposit of brake pipe and the cleaning method of other foreign material.
Technical scheme of the present invention is that the characteristics of this cleaning method are: step 1 fitly is positioned over the brake pipe after disintegrating on one machine table; Step 2 is at the uniform velocity sent into a water jet shower nozzle and to be carried out jet emission in the brake pipe, and the rotation voluntarily by shower nozzle and at the uniform velocity moving ahead makes jet beam carry out brute force to foulant in the brake pipe and hits fragmentation and peel off; According to the preceding line speed of the fouling situation fluid jet nozzle of brake pipe be 0.5-2.8 rice/minute, specified hydraulic pressure is 35-80MPa, the specified water yield is 50-80L/ minute; Treat fluid jet nozzle when the other end of brake pipe stretches out and finished the cleaning of whole brake pipe, closed control valve is extracted fluid jet nozzle out in brake pipe; Step 3 is at the uniform velocity sent into a pressure-air shower nozzle in the brake pipe, purges carrying out high pressure in the brake pipe with high-pressure blast, and the interior remaining dirt of brake pipe is purged to brake pipe; The preceding line speed of pressure-air shower nozzle be 0.5-2.8 rice/minute, rated pressure is 0.5-1.0MPa; Treat that the pressure-air shower nozzle stretches out and the high pressure of having finished whole brake pipe when purging from the other end of brake pipe, closed control valve, with the pressure-air shower nozzle from managing interior extraction.
Another characteristics of the present invention are: after finishing described step 3, an atomizer is at the uniform velocity sent in the brake pipe, made the water-based antirust (as KJ-292-1, EP-12, VCI-377 water-based antirust) of atomizer ejection be sprayed on the brake pipe inwall equably; The preceding line speed of atomizer be 0.5-2.8 rice/minute, shower nozzle to be atomized is when the other end of brake pipe stretches out and finished the spraying of whole brake pipe, closed control valve is extracted atomizer out in brake pipe.
At last, the two ends of the brake pipe that will clean with the stifled cover of plastics screw, but prevent that foreign matter from entering and protection tube terminal filament button.
The present invention has following advantage and effect: 1, owing to adopt high-pressure spray that brake pipe is carried out the jet cleaning, high-pressure spray has very strong cleaning force, so deposit and other foreign material of brake pipe inwall can be cleaned up; With the high-pressure blast brute force foreign material that wash are blown out outside the brake pipe simultaneously; So this method can thoroughly be removed deposit and other foreign material in the brake pipe.2, this method is simple and practical, efficient is high, only needs a few minutes just brake pipe can be cleaned out.3, the cleaning cost is low, owing to do not need other special washing agent, only needs water and air, so it is very low to clean cost.
