Ten steps of generating set debugging

2019-11-20 20:34  |

        The diesel generator set is a power generation device which has the advantages of quick starting, convenient operation and maintenance, less investment and strong adaptability to the environment. The power supply mainly used for various main power sources and emergency power supplies can also be applied to the electric power supply of the electric power propulsion system, and the importance of the power supply is self-evident. Therefore, the commissioning of the generator set before operation is also essential

1. add water 
 turn off the discharge valve first, add clean drinking water or purified water until tank cap, then close the tank cover

2.  Add oil
 
The oil is divided into summer and winter, and different oils are used in different seasons. For diesel engines, add 8 or 11 oil in winter and 14 oil in summer.
 
In the process of adding oil, pay attention to observe the vernier scale until the oil is added to the position where the caliper scale is saturated. Cover the oil cover. Do not add more. Excessive oil will cause the oil to be drained and the oil to burn.

3.Divide into oil and return oil
 
To ensure that the machine's oil intake is clean, it is generally necessary to allow the diesel to settle for 72 hours. Do not insert the oil into the bottom of the cylinder to avoid sucking dirty oil and clogging the tubing.

4.supply  diesel
 
 First loosen the nut on the hand pump and hold the handle of the diesel generator hand pump and pull it evenly until the oil enters the pump.

5.Let Air out
 
Loosen the bleed screw of the high pressure oil pump first, then press the hand oil pump and see the oil and air bubbles in the screw hole overflow until the oil is all in the oil. Tighten the screw.
 
 
6.start the motor
 
Distinguish between the positive and negative poles of the motor and the positive and negative poles of the battery. The two batteries should be connected in series to achieve a 24V effect. Connect the positive pole of the motor first. When connecting the positive pole, do not let the terminal contact other wiring sections. Then connect the negative pole of the motor and be sure to tighten it to avoid burning the wiring section.
 
7.air switch
 
The switch should be in a separate state before the machine is started or when the machine is not in the power-on state. There are four terminals at the lower end of the switch. These three are three-phase live wires. The Cummins generator set is connected to the power line, and the independent side is zero. The power supply that the line and the neutral line are in contact with any of the fire lines is 220V. Do not use one third of the rated power of the generator.
 
8.the instrument part
 
①. During use, the current meter can accurately read the power used;
 
②The voltmeter can detect the motor output voltage;
 
③ the frequency meter must reach 50Hz, which is the basis for detecting the speed;
 
④ The current and voltage conversion switch is for detecting the instrument data of the motor;
⑤ The oil pressure gauge detects the oil pressure of the diesel engine. At full speed, it should be no less than 0.2 atmosphere.
⑥, the tachometer, the speed should be located at 1500 rpm;
 
⑦. The water temperature gauge should not exceed 95 degrees during use, and the oil temperature should not exceed 85 degrees.

9  start
 
Turn on the ignition switch, press the button, release the generator set after driving, run for 30 seconds, turn the high and low speed switch, the machine will slowly rise to the high speed from idle speed, check the reading of all the meters. In all normal conditions, the air switch can be closed and the power transmission is successful.
 
10  parking
 
First turn off the air switch, cut off the power supply, adjust the diesel engine from high speed to low speed, let the machine idle for another 3-5 minutes, then turn off the machine.
