1. 柴油发电机组二次灌浆地面凿打粗糙， 见到水泥混合石块为准。
The second-grouting floor of the unit installation shall be chiseled to see the stones mixed in concrete.
The bottom side of the line plate shall be cleaned up (no oil stains), and all the screw holes on the plate shall be tapped with screw taps.
The location of the diesel engine shall be marked according to the drawing requirements. Seat pads of the diesel engine shall be leveled and smoothed using cement mortar. Screw jacks are put on the seat pads and adjusted to the same height using a leveling instrument. Then the screw jacks shall be fixed tightly and their positions recorded. .
Install the patterns required for the second-grouting floor of the engine.
Insert the foundation bolts of the unit into reserved holes, and the bolts shall be well cleaned and put on with protectors before inserting.
Put all line plates and U-shaped filling blocks of the unit beside the engine, so they can be used conveniently later. The line plates shall be fitted with adjustable bolts.
Remove the transport seat pads when the engine is shifted on the engine base, install the line plate baseboard, and place the screw jacks according to the installation position. Place the unit 100mm high from the floor according to the location and the elevation (the deviation shall not be more than 3mm from the foundation central line, and assist by a heavy equipment company). Hang a plummet on the front and back sides of the diesel engine, respectively, for aligning.
Put the dried river fine sand beside the diesel engine, so as to be conveniently filled into the foundation screw mounting holes.
Roughly adjust the engine level with a leveling instrument when the engine is put in place, and then install the barring gear.
Fine adjust the engine level to meet the requirements (according the position sequence), and then deliver the engine for overhaul.
Align and connect the generator to the engine. Mark the location of the generator installation, basing on the preliminary position of the diesel engine. Place the baseboard of the generator, the line plates and the generator chock according to the location and elevation requirements.
Readjust the diesel engine within the level range specified after the overhaul.
Check the joining surfaces of the generator bearing after finishing the unit alignment. Fill the dried river fine sand into the foundation screw mounting holes of the diesel engine. Check again. Pour non-shrinking cement, preserve moisture for 15 days and measure data, and perform the acceptance inspection.
One month after the second grouting, recheck the unit alignment. Screw tightly the fixed blots according to the required procedures. Check the unit alignment once again and finish the diesel generator positioning.
