Description
Technical field
The present invention relates to a kind of chemical removal methods, the chemical removal methods that particularly a kind of aircraft engine spark coil torch is chewed the inner chamber carbon deposit.
Background technology
Torch is chewed and is also claimed ignition electric nozzle, igniting when being used for the aircraft engine starting.General mover torch is chewed the oil nozzle bore only about 0.2mm, and internal diameter also is processed with spiral-line, and this hole has 50mm length approximately, just turns round into two sleeve pipes more inward, and the slit is also only about 0.2mm.Torch is chewed in case by the carbon deposit obstruction, and mover can't be lighted a fire.Because it is special that torch is chewed inner-cavity structure, chews internal diameter and will dredge the torch that is blocked, very difficulty can only renew part.
How clearing up torch and chew interior carbon deposit, is this area technical problem to be solved.
Summary of the invention
Technical problem to be solved by this invention has provided a kind of aircraft engine spark coil torch of can clearing up and has chewed the chemical removal methods that the aircraft engine spark coil torch of inner chamber carbon deposit is chewed the inner chamber carbon deposit.
In order to solve the problems of the technologies described above, the chemical removal methods that aircraft engine spark coil torch of the present invention is chewed the inner chamber carbon deposit comprises: torch is chewed passed through following steps successively: industrial naptha washing, electrochemical deoiling, hot wash, chemistry boil and wash, dry, check except that carbon deposit, cleaning, hot water.The step that said chemistry removes carbon deposit comprises: torch is chewed be immersed in chemistry and removed in the carbon deposit solution 1-3 hour; Described chemistry removes carbon deposit solution and comprises:
Polyoxyethylene aliphatic alcohol ether, 5-10g/l;
T 46155 octyl phenolic ether, 3-6g/l;
The dodecyl diglycollic amide, 5-10g/l;
Sodium laurylsulfonate 1-3g/l;
Sodium hydroxide, 40-60g/l;
Trisodium phosphate, 10-15g/l;
Tripoly phosphate sodium STPP, 10-15g/l;
Sodium Silicofluoride 98min, 8-12g/l;
Water, surplus.
For improving efficient and the effect that chemistry removes carbon deposit, to remove in the step of carbon deposit at said chemistry, the temperature that chemistry removes carbon deposit solution is 80-95 ℃.
The method of described electrochemical deoiling is immersed in except that 0.5-1 in the oil solution hour for said torch is chewed, and should remove oil solution and comprise: sodium hydroxide, 20-40 g/l; Yellow soda ash, 20-40 g/l; Tsp, 20-40 g/l; Water glass, 3-5g/l; The temperature of this solution is 80-95 ℃.
The step of said cleaning is cleared up for adopting High-Pressure Water or high pressure draft that torch is chewed, and chews the carbon deposit that is loosening or the state that comes off of inner chamber with the said torch of Ex-all.
The present invention has positive effect for prior art: the chemical removal methods that aircraft engine spark coil torch of the present invention is chewed the inner chamber carbon deposit, and step is simple, with low cost, easy and simple to handle, do not hinder the matrix that torch is chewed; Carbon deposit is removed the back torch and is chewed and can reuse, saving fund, remarkable in economical benefits.And torch is chewed the ability routine cleaning, then can stop fully to chew the fault that obstruction causes because of torch, aircraft engine is run well has positive effect, and military and civilian's aviation users is all had higher popularization and value of services.
Embodiment
The chemical removal methods that the aircraft engine spark coil torch of present embodiment is chewed the inner chamber carbon deposit comprises: industrial naptha washing, electrochemical deoiling, hot wash, chemical method boil and wash, dry, check except that carbon deposit, cleaning, hot water.
The torch that to clear up is earlier chewed in industrial naptha and is washed, and washing is chewed this torch afterwards and carried out electrochemical deoiling, and electrochemical deoiling can remove in the oil solution in surface treatment commonly used and carry out, and temperature need remain between 40-80 ℃, needs in solution, to soak 0.5-1 hour; Use the hot water injection after oil removing is accomplished, the impurity such as gasoline chewed of this torch are promptly cleaned out like this; Next just need chew inside and carry out chemical method except that carbon deposit to torch.
When chemistry removes carbon deposit, torch chewed be immersed in chemistry and remove in the carbon deposit solution, the time is 1-3 hour, looks described torch and chews the loosening carbon deposit of inner chamber and can become flexible or come off and decide, and temperature need remain between 80-95 ℃.
Described chemistry removes carbon deposit solution and comprises:
Polyoxyethylene aliphatic alcohol ether, 7.5g/l;
T 46155 octyl phenolic ether, 4.5g/l;
The dodecyl diglycollic amide, 7.5g/l;
Sodium laurylsulfonate 2g/l;
Sodium hydroxide, 50g/l;
Trisodium phosphate, 12.5g/l;
Tripoly phosphate sodium STPP, 12.5g/l;
Sodium Silicofluoride 98min, 10g/l;
Water, surplus.
Chemistry of the present invention remove carbon deposit solution to carbon deposit, grease have very strong wetting, permeate, peel off, dissolving and dissemination, steel part is had rust inhibition.This solution does not corrode other materials such as copper spare, for the not serious part of surperficial carbon deposit, puts into this solution 5-10 minute, and carbon deposit can be removed totally; And the torch that is seriously stopped up endoporus by carbon deposit is chewed, then need under comparatively high temps, soak, the time is long slightly; Should often shake part therebetween in order to oozing in the solution, and take out in clean boiling water, to boil and wash repeatedly, peel off in matrix and by efflorescence dissolved carbon deposit and can from the hole, flow out.
After the carbon deposit that comes off in said torch chewed is cleaned out, boil with hot water and to wash, the thorough Ex-all of the chemical solvents that said torch is chewed, it is unobstructed that washed torch is chewed inner chamber, and outward appearance is clean as new.
Subsequently said torch is chewed and dried processing, bake out temperature is 105-115 ℃, and the time is 0.5-1 hour.
Through after the check, said torch is chewed and can be used at last.
As further preferred scheme, implementing chemistry except that during the step of carbon deposit, the taking-up torch was chewed on soft worktable and is gently knocked in per 30 minutes; Torch is chewed the loosening carbon deposit of inner chamber and can be become flexible, come off; Available in case of necessity pressurized air blow pressure, and cooperate hot water to boil to wash, until the Ex-all of inner chamber carbon deposit.
The method of described electrochemical deoiling is immersed in except that 0.5-1 in the oil solution hour for said torch is chewed, and should remove oil solution and comprise: sodium hydroxide, 30 g/l; Yellow soda ash, 30 g/l; Tsp, 30 g/l; Water glass, 4g/l; The temperature of this solution is 80-95 ℃.
