Spray gun in spraying equipment described in the utility model is replaced by hairbrush, the cleaning work before spraying to insulator.
A kind of transformer station based on above-mentioned spraying equipment support insulator RTV spray painting technique, specifically includes following steps.
A. spray solution is prepared.
RTV to be diluted before spraying, raw material has RTV coating and solvent, and in the present embodiment, solvent uses three atmosphere ethane, trichloroethanes to be 1:4 with the volume ratio of RTV coating.Being stirred evenly by RTV liquid in container, act out the solid portion of surface crust, be spray solution, the storage tank loading spraying equipment is stand-by.

VRTV=S*h
Wherein: S is the surface area of insulator, h is coating wet thickness.
Changing weight into, the weight of required RTV coating is:
W R T V = V R T V 1000 * 1.19
Or the sprayable 0.9m of 1KgRTV coating2.Algorithm above all includes the loss of 15%.
B. clean insulator surface, wrap up non-spraying position.
Clean the insulator of general contamination with glove, dry cotton, fouling and new insulator surface to especially severe have the unconventional states such as grease, do supplementary means with chain type flexible steel pompon, the cleaning agent of cleaning coating device, be purged;Vertical type support insulator to converting equipment, interior edge, outer are cleaned piecewise, do not stay dirt.
Take non-spraying positions such as flange, wire clamp, corona circle, insulator hardwares to wrap up preventing from polluting.Preservative film that lapping absorption affinity to be used is big, single-coated foam;It is wound around in order, it is ensured that not at omission, and corner twines jail, forbids loose flying away.It is used as special elastic anchor ear.
C. by the heating arrangements on spraying equipment, spraying operation temperature is adjusted more than-20 DEG C;By the humidification apparatus on spraying equipment, adjust operating environment humidity in the range of 20%~80%.
D. spraying equipment is used to carry out spraying operation.Spraying operation uses around insulator successively multipass spraying coating process, specific as follows.
D1. carrying out first pass coating spraying around insulator, first pass coating must be thin, and seen from naked eyes, similar transparent spray film is attached to surface of the work, and thin coating refers to rapidly do. and after then, layer is easier to attachment.
D11. regulation spray pump pressure is set in 8MPa, and air compressor machine air outlet valve pressure is adjusted to 0.3MPa, and the regulation button after Shi Pen limit, limit fine setting spray gun, the coating making spraying equipment spray reaches optimal spray pattern.
D12. spray equipment is advanced at insulator to be sprayed, makes insulator access arrangement spraying area;Controlling radial movement mechanism regulation spray gun rifle mouth to workpiece distance by controller is at 20~30cm, and the wide 30cm of fan, rifle mouth and horizontal line angle are 30 °;Fix spraying equipment, holding position constant.
D13. gun traffic is regulated, spray gun spray nozzle is transferred at nethermost insulator flabellum, the sliding door of outer cover is closed, control rotating mechanism by controller and turn 180 ° of sprayings around insulator clockwise, completing the spraying of a flabellum, the speed of service of spray gun is 30~60cm/s.When speed is less than 30cm/s, the painting thickness of formation, it is easily generated sagging;When the speed of service is more than 60cm/s, the film of formation is thin, is easily generated show-through defect.
Control up-down mechanism by controller the most again and move the distance set in advance straight up, spray around insulator counterclockwise, complete the spraying of second flabellum.
D15. repeating step D13~D14, to the last an insulator flabellum has sprayed, and completes a spraying of whole insulator flabellum.
D2. opening heater and carry out the first coated and dried, drying time is 5~10min.
D3. step D1~D2 are repeated, during until whole insulator sprays 6-7 time, measure coating layer thickness, if can measure with wet film thickness gauge time the most dry, wet film is up to 0.7-0.8mm, and after solidification, insulator surface coating layer thickness i.e. can reach 0.35~0.5mm, when color gradually shows silicon rubber particular color, after work piece substrate color is completely covered qualified, i.e. complete spraying.
Spraying after which floor time, the pressure-regulating valve on the air control valve on supply air line and coating pipeline can be regulated again according to the viscosity of spray regime and coating and obtain bigger spray regime and bigger emitted dose.
E. coating checked and carry out defect elimination process.
The process of spraying process is carried out management and control, and ground installation personnel with the naked eye check insulator coating and gold utensil with telescope in multiple angles, find weak point notice spraying specific responsibility defect elimination, it is ensured that spraying once success.
After having sprayed, need finishing as surface is irregular, with foam pad or brush, drop-wise RTV at the blocked up place being coated with is removed;Cover light or impaired surface are with soft brush coating;Insulator chain exist be difficult to individually spray the dead angle put in place, need brush brush spray less than place, brush brush can be selected for the densest soft hairbrush; also need dilute RTV, in order to avoid RTV the thickest be combined with preceding layer bad, during with brush brush; often to clean hairbrush, smear uniformly, available same protected effect.
The special construction of insulator often makes the coating of porcelain patticoat root relatively thin, the most often adds painting with spray gun.When adding painting, the scope of penetrating of disputing minimum to be transferred to, so that coating focuses on root, the insulator installing horizontal direction can divide three direction sprayings;To the highest porcelain vase, first it is coated with 120 ° from bottom;To the highest porcelain vase, then first from upper topcoating 120 °, respectively it is coated with the scope of 12 ° from both sides, in order to operation.
The thickness difference of same insulator different parts less than the standard of 0.2mm, the appearance uniform of coating, smooth, smooth, do not pile up, do not trickle, bubble-free, without wire drawing, N/D, without holiday.
In spraying process, if it find that the coating of ejection sprays fewer and fewer, then show that spraying equipment is likely to occur blocking, at this moment spraying equipment is carried out.During cleaning, half liter of trichloroethanes is poured into pressure cup, and connects pipeline by method of attachment during injection;Open two sprays and rob control valve, it is allowed to liquid and free air flow, with the trichloroethanes of rifle jet atomization, after the most several seconds, close air valve, continue remaining trichloroethanes in jet cup;This time the trichloroethanes used vessel of ejection is caught, and is used for marking releasing RTV.Take off pressure cover after having sprayed, wipe clean with clean rag, again pour clean trichloroethanes into, carry out second time and clean;This time cleaning, need to take off air nozzle, make solvent spray towards hole from both direction, in bucket, solvent sprays a period of time, pours out the solvent of remaining, and wipes clean with clean rag.During being coated with if disputed, midway stop-spraying more than one hour, then need cleaning coating device as stated above.
