1-signalling means, 2-applies insulating coating end, 3-threaded ends, 4-flank, 5-axle journal, 6-aperture, 7-rotating disk, 8-power shaft, 9-fixed bar, 10-quarter butt.
Detailed description of the invention:
Below in conjunction with embodiment, the present invention is described in further detail.
The process that signalling means coating is repaired, concrete steps are as follows:
Step 1. removes remaining coating on signalling means
As described in Figure 1, signalling means 1 is L-type structure, one end is coating insulating coating end 2, the other end is threaded ends 3, the flank 4 of coating insulating coating end 2 is coated with insulating coating, threaded ends is light face, on the flank 4 that need apply insulating coating and with the light over glaze neck 5 of described threaded engagement on respectively have a diameter to be the aperture 6 of 1mm, lead to signalling means 1 enclosure interior; Adopt mechanical car processing method to remove the remaining coating being attached to thread surface, ensure remaining coating complete removal and efficiency is higher;
Step 2. removes the lubricating oil in housing
Signalling means is operated in the environment of lube pipe, and inside cavity is filled with lubricating oil, does not remove the lubricating oil in clean housing, again during coating, and need the aperture on the screw thread of applying coating to ooze out combination that lubricating oil directly affects coating and threaded base.Compressed air is taked to be blown to signalling means inside by signalling means housing light over glaze neck place aperture, powerful pressure makes the lubricating oil in cavity be flowed out completely by the aperture that need apply on the screw thread of insulating coating, then with alcohol, the signalling means end of thread is cleaned up, check with oil-Absorbing Sheets, without oil stain, dry in atmosphere afterwards;
Step 3. signalling means protects
Step 3.1 uses fluorine plastic film to carry out shutoff protection to signalling means thread head gap and two U-type groove, prevents epoxy modified silicone adhesive entering signal device inner;
Step 3.2 uses silicone glass adhesive tape to be wound around in narrow meshed for the signalling means bottom of thread smooth over glaze footpath;
Aperture on screw thread is blocked by the fuse of the diameter 1.2mm that step 3.3 uses round and smooth file to repair;
Step 4. gluing
Fixture is installed on the individual event permanent-split capacitor motor with speed regulator by step 4.1, and the signalling means that need repair is installed on fixture;
Step 4.2 uses screwdriver to dip epoxy modified silicone adhesive, signalling means needs reparation position smear epoxy modified silicone adhesive, and organic silica gel is smeared to needs the whole surface of reparation position;
Step 4.3 switches on power, and motor speed is adjusted to 50-70R/min, and motor drives signalling means uniform rotation, makes the insulating coating of signalling means rotate natural shaped by self;
Become liquid before the coating of organosilicon stick, because Action of Gravity Field can not well be fixed on the annex of column in the quiescent state, and due to accessory structure complexity, particular manufacturing craft can not ensure the shaping of liquid sealant very well and prevent from entering annex inner chamber.
Step 4.4 signalling means solidifies 8 hours under motor drives rotation, cuts off the electricity supply afterwards, static maintenance solidification in 24 hours under natural air state;
As shown in Figure 2, the fixture of described step 4.1 comprises rotating disk 7, and rotating disk 7 one end is provided with power shaft 8, and described power shaft 8 is connected with motor output end, and rotating disk 7 other end is provided with two fixed bars 9, is used for fixing signalling means; Described fixed bar 9 can be threaded composition for multistage quarter butt 10;
Step 5 is repaired and is checked
Step 5.1 uses open-end wrench S10 to be decomposed from fixture by the signalling means completing solidification;
Step 5.2 use group file and No. 500 sand paper carry out contouring by accompanying drawing to the coating of signalling means, measurement inspection is carried out to the coating layer thickness slide calliper rule of signalling means, record coating end thinnest part thickness and be not less than 0.1mm, check with filter core after finishing, signalling means can loading and qualified,, carry out visual examination to coating, insulating coating has not allowed crackle, has fallen the External Defects such as block;
Step 5.3 removes fuse, removes the fluorine plastic film on clean signal device and silicone glass adhesive tape.
Finally should be noted that: above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit, although with reference to above-described embodiment to invention has been detailed description, those of ordinary skill in the field are to be understood that: still can modify to the specific embodiment of the present invention or equivalent replacement, and not departing from any amendment of spirit and scope of the invention or equivalent replacement, it all should be encompassed in the middle of this right.
