6.2.4.3. Repair of a regulator of pressureRepair of a regulator of pressure should be spent only in exceptional cases; it is recommended to replace it. On regulator repair following operations are supposed.
Cover and lining replacement
At installation of a new cover watch that the cover and a lining were absolutely pure and that the lining was established correctly. After installation tighten screws against the stop.
If in the regulator case there is a dirt, clear contacts and other parts of a regulator.
The soldering of breakages of electroconnections
The soldering make with application of a neutral gumboil, in a small amount, protecting from an overheat isolation. Remove surpluses of a gumboil after the soldering as its rests, evaporating from heat allocated with a regulator in an operating time, can pollute contacts.
Clearing of contacts
PERFORMANCE ORDER |
1. For clearing of contacts remove a spring of an anchor and, having weakened a nut 4 (fig. the Regulator of pressure РР-380 see), raise a rack 6 motionless contacts of 1st step. |
2. Flat velvet надфилем accurately smooth out contacts, deleting thus burnt materials and oxides on all surface. Надфиль should be absolutely dry, washed out in pure spirit or gasoline. The deepenings which have arisen on contacts because of подгорания, should be smoothed out the pure steel pointed hairpin. |
3. Remove sawdust of silver from the regulator case, having blown its dry and pure air. |
4. Establish into place an anchor spring. Movement of a rack 6 adjust a backlash (1,4±0,07) mm between an anchor and the core, watching correctness of a contact of contacts. |
5. Moving of a rack 5 adjust distance between contacts of 2nd step to (0,45±0,1) mm, watching correctness of a contact of contacts. |
6. Tighten a nut 4. |
7. Establish into place a lining and a cover then check up a regulator at the stand and if necessary adjust. |

Clearing of a regulator of pressure
In case of penetration into a regulator of extraneous substances, after clearing of contacts, before check and adjustment accurately wash out a regulator spirit or pure gasoline and then dry up it (without a cover) in the furnace at temperature 120 ° With within two hours. Then check up a regulator at the stand and if necessary adjust.
