2.7.8. Removal, check and installation of fuel nozzles
Removal
Dump residual pressure in топливопроводе that there was no fuel emission.
|
ATTENTION
To cover the union топливопровода with rags, to prevent fuel emission under the influence of residual pressure in топливопроводе.
|
Remove a fuel stage together with nozzles.
|
ATTENTION
At removal of a fuel stage accept precautionary measures not to allow loss of nozzles.
At removal of nozzles take measures for the prevention of an effluence of fuel.
|
Check of a technical condition
|
|
Fig. 2.271. Check of resistance of a winding of a nozzle
|
Check resistance of a winding of a nozzle, having attached an ohmmeter to its conclusions (fig. 2.271). Resistance of a winding of nozzles: 15,9±0,35 Ohm at 20 °C.
At discrepancy of resistance to norm replace a nozzle.
Installation
Establish on a nozzle a new sealing and heat-shielding ring (fig. 2.272). Put on a sealing ring solvent, veretenny oil or gasoline.
Establish a nozzle in a fuel stage, turning a nozzle to the left-to the right (fig. 2.273). Be convinced of ease of rotation of a nozzle.
|
NOTE
The complicated rotation of a nozzle indicates a possible distortion of a sealing ring. Remove a nozzle, insert it into a fuel stage and again check ease of rotation.
