Regulator check and regulate at the stand having the generator, the storage battery, the thermostat and the electric motor with adjustable frequency of rotation in a wide range. A regulator with the closed cover establish at the stand tips downwards.
The scheme of electric connections of the stand is shown on fig. the Scheme of check of a regulator of pressure at the stand.
Special attention turn on reliability and the minimum resistance of connections of wires that wires from the switch 2 incorporated directly to a clip «30» generators and the tip «15» regulators, and the regulator case – directly with the generator case. All wires should be whenever possible shorter.
At control checks at the stand do not suppose work of a regulator with the disconnected storage battery since it can damage regulator contacts. Bulbs 6 supervise work of the generator and if it is serviceable, should have identical heat.
| PERFORMANCE ORDER |
| 1. Before check a regulator warm up in the thermostat during 15–18 mines at (50±3) ° With, feeding a winding of a regulator with a current at pressure 12–13 V.Naprjazhenie it is established by a rheostat 7 at the included switches 2, 8, 9 and the idle generator. |
| 2. Immediately after warming up start check and adjustment of 2nd, and then 1st steps and watch that the adjusted pressure was steady, i.e. sharply did not fluctuate. |
| The control of 2nd step |
| 3. Establish frequency of rotation of a rotor of the generator of 5000 mines-1. |
| 4. A rheostat 7 establish a current of loading of the generator 2–12 And. |
| 5. Check up pressure of the generator which should be (14,2±0,3) Century |
| 6. If it differs, stop the generator, disconnect the storage battery, uncover a regulator and, turning in an arm of a spring 10 (fig. the Regulator of pressure РР-380 see), ослабьте (if pressure high), or increase (if a low voltage) its tension. |
| 7. Then establish into place a cover of a regulator and again check up pressure of 2nd step. |
| 8. After the termination of check and adjustment of 2nd step immediately check up 1st step of regulation. |
| The control of 1st step |
| 9. At frequency of rotation of a rotor of 5000 mines-1 a rheostat 7 (the Scheme of check of a regulator of pressure fig. see the stand) establish a current of loading 25–35 A.Pri it pressure should be no more than on 0,7 In more low value received at adjustment of 2nd step. |
| 10. If pressure does not keep within these limits stop the generator, disconnect the storage battery, uncover a regulator, ослабьте a nut 4 (fig. the Regulator of pressure РР-380 see) and move a rack 6 on 0,1–0,2 mm. |
| 11. When pressure raised, a rack shift downwards, and if lowered – upwards. Simultaneously shift a rack 5 to keep a backlash (0,45±0,1) mm between contacts of 2nd step. During this operation watch coincidence of axes of contacts of 1st and 2nd steps. Anchor contact should not fall outside the limits contacts on racks. |
| 12. Tighten a nut 4, establish into place a cover, again check up a regulator (both 1st, and 2nd step) and if necessary repeat operations before reception of exact adjustment. |
| 13. After the termination of adjustment a regulator cover carefully clear and establish on a hot regulator to reduce to a minimum moisture absorption. |
