Diesel generator accessories include cylinder mats, injector platens, oil seals and so on. The complexity of the diesel generator structure and the fineness of the fittings determine the higher requirements for the assembly operation. Therefore, it is necessary to use the relevant personnel Personally operate. The following describes the details of the operation of the assembly of diesel generator accessories.
(1) cylinder pad: assembly, the side of the curling should be toward the cylinder head; if installed anti, will early leakage, burning cylinder pad, affecting its service life.
(2) the top of the piston horseshoe-shaped groove or the top of the peach-shaped tip side should be facing the top; if installed against, is not conducive to the mixture of fuel and air, unburned fuel can not produce secondary vortex movement and combustion is not complete, resulting in diesel Can not start or start after work is not normal.
(3) connecting rod and piston assembly; should make the small end of the rod and the piston at the top of the horseshoe-shaped groove or the top of the peach-shaped tip of the same side of the upward direction; otherwise, resulting in connecting rod small end sleeve and piston pin can not be lubricated, And the formation of dry friction.
(4) connecting rod of the upper and lower tiles: If the new replacement of the pad, then regardless of the upper and lower; if after the use of the bearing, according to the original location of the complex, should not be on the next transposition, otherwise it will affect the shaft The relationship between neck and pad.
The same time as the above-
(5) combination of connecting rod and connecting rod: connecting rod big end and connecting rod cover on the back of the assembly mark, the combination should be marked with the same side. Otherwise, can not guarantee the original rod diameter of the original processing accuracy, but also damage the correct cooperation with the shaft.
(6) fuel injector plate: one side of the pressure plate is flat, the other side of the circular surface. Installed so that the arc surface facing the injector body to ensure that the injector is pressed when the center without skew, or easy to make the seat hole out of the air leakage.
(7) oil seal: all the oil seal, such as crankshaft oil seal, start shaft oil seal, etc., should be with a self-tight spring side of the body. If installed, the crank box sealed lax, so that oil leakage.
In order to ensure that the diesel generator can run smoothly and reliably, the assembly process must be standardized. We recommend that after the assembly is completed, the inspection of the various parts of the fuselage will be carried out, and then the assembly of the main components of the diesel generator will be carried out. A few minutes of trial run, test run normal, you can put into use.
