Diesel Generator Set Reduced Resistance Users Can Not Arbitrarily Cancel The Thermostat
Nov 03, 2017

The thermostat can automatically adjust the working temperature of the Diesel Generator Set Generator Set coolant, and when the thermostat is disassembled, it should be careful not to touch the wound. Check the thermostat work is normal, you can put the thermostat in the water slowly heating, to observe the thermostat outlet valve opening and fully open the temperature, whether within the specified range.

In addition to the 2-cylinder machine and part of the 4-cylinder machine Mining 5-only section Wenner, other models a overlapping using two thermostat in parallel, this can increase the channel section of two thermostat, reduce resistance users can not casually cancel the thermostat, when found that the thermostat failure should be changed, or will affect the normal operation of Diesel Generator Set Generator Set.

The generator battery charging generator adopts silicon semiconductor rectifier charging generator (hereinafter referred to as charging generator), and the Diesel Generator Set engine works as a charging generator for the battery. According to the Diesel Generator Set engine model, with different specifications of the charging generator.

1. The charging generator must be combined with the corresponding charging generator regulator (except for the integral generator) and the battery.

2, the wiring must be correct and reliable, positive, negative should not be wrong, otherwise it will damage the generators and other electrical components.

3, the front and rear end cover is equipped with rolling bearing, uses the compound calcium base grease lubrication. After each use 750h should replace one

The amount of padding should not be too much, especially the rear cover of the rolling bearing, such as adding too much easy to cause grease overflow, splashing in the two will make contact bad, affect the performance of the generator.

4, when the power generation run, do not allow the use of screwdriver (screwdriver) and other metal items will be the positive pole and the chassis or the cathode short to observe whether there is a spark to determine if the generator power generation, so easy to burn the generator.

5, self-excited alternator, when one or two months do not use (operation), there may be no power generation phenomenon, at this time, as long as the Diesel Generator Set engine (no-load) speed to pull up a little higher, you can resume normal power generation.

In order to achieve good combustion and normal operation of Diesel Generator Set engine, and obtain the most economical fuel consumption rate, every time Diesel Generator Set engine working 500h or every time after disassembly, we must carry out the fuel injection advance angle inspection and adjustment.

The adjustment method of fuel injection advance angle:

1 First method: Remove the first cylinder of high-pressure tubing, rotate the crankshaft, so that the first cylinder piston at the beginning of the expansion stroke, at this time the flywheel shell of the pointer on the flywheel on the "0" degree line. Then according to the Diesel Generator Set engine running direction reversal crankshaft, so that the check window of the pointer on the flywheel on the equivalent of the specified angle, and then loosen the fuel injection pump drive joint plate on the two tightening screws, according to the fuel injection pump rotation direction, Slowly and evenly rotate the fuel injection pump cam to the 1th cylinder outlet oil face has just fluctuated instantaneously and screwed up the two screws on the plate.

2. The second method: Remove the first cylinder high-pressure tubing, rotate the crankshaft, so that the 1th cylinder piston at the end of the compression 40° around, and then the Diesel Generator Set engine rotation direction slowly and evenly rotate the crankshaft, while paying close attention to the fuel injection pump 1th cylinder oil surface situation. When the oil surface has just fluctuated for a moment, that is, the 1th cylinder fuel injection began, at this time the check window on the flywheel on the dial of the scale value is the fuel injection ahead of the number of angles. If this angle does not conform to the specified range, the two screws on the splice plate can be loosened, turn the fuel injection pump camshaft to adjust the angle (the scale of the drive shaft, each grid is equal to the crankshaft corner 3°), the advance angle is too small, the camshaft rotates according to the running direction, then rotates in the reverse direction of the operation, then twists the two screws on the close plate, Repeat the check again until the scope of the work is complete.

Sometimes, check the fuel injection lead angle and the specified value difference is very little, it is not necessary to loosen the joint disk to rotate the fuel injection pump camshaft, and as long as the injection pump four installed screw pins micro-relaxation, so that the fuel injection pump body to make a small rotation to adjust, its rotation direction should be the opposite of the second method, the screw tightening after adjustment.

In general, the 1th cylinder fuel injection advance angle adjustment is correct, the other cylinders of the fuel injection ahead of the angle of the pump cam camshaft, do not have to check separately.
