How to accept new or overhauled diesel generator sets?

Due to the large capacity of diesel generator sets, they can run in parallel and have a long continuous power supply time. They can also operate independently without parallel operation with the regional power grid. They are not affected by power grid failures and have high reliability. important power. In order to ensure the normal use of the diesel generator set, it is very necessary to debug and accept it before it is put into operation. Only after strict technical acceptance, when its safety, power characteristics, power quality, noise and other performance indicators meet the standards, the diesel generator set can be put into normal use.

Diesel generator sets

 

       Due to the large capacity of diesel generator sets, they can run in parallel and have a long continuous power supply time. They can also operate independently without parallel operation with the regional power grid. They are not affected by power grid failures and have high reliability. important power. In order to ensure the normal use of the diesel generator set, it is very necessary to debug and accept it before it is put into operation. Only after strict technical acceptance, when its safety, power characteristics, power quality, noise and other performance indicators meet the standards, the diesel generator set can be put into normal use.

       1. When purchasing the machine, the acceptance work should be done well.

       1. Read the manual carefully to understand the performance, structural characteristics and operation methods of the machine, and check the tools and spare parts one by one to be familiar with it.

       2. Appearance inspection and acceptance. Check whether the external parts are complete, whether the parts are installed correctly, whether the surface skin is falling off, whether the bolts and nuts are tightened, and whether the cotter pin is locked. When necessary, fill in a list of tools and spare parts or request a replacement to the sales department.

 

       2. Inspection of newly purchased diesel engines. Newly purchased diesel engines should focus on the following items:

       1. Startup Check

       Add fuel, lubricating oil, and coolant as needed. Rotate the crankshaft with the crank, observe whether the decompression mechanism works normally, and judge whether the compression stroke pressure of the diesel engine is normal. If the diesel engine cannot be started at one time, stop the vehicle to check whether the starting method is correct, whether the position of the decompression handle is correct, and whether the fuel injection sound is clear. If the influence of the season is to be considered in winter, whether the water heater needs to be started after heating. If the engine can be started within three times, the diesel engine has good starting performance

       2. Governor inspection

       Pull the throttle to observe whether the speed of the diesel engine increases with the increase of the throttle, and decreases with the decrease of the throttle, and whether the speed regulation is sensitive; the speed of the diesel engine drops sharply, the throttle valve shrinks sharply, stabilizes at the minimum speed, and there is no flameout phenomenon. The governor works fine

       3. Parts inspection

       Pay attention to check whether the accessories of the diesel engine, special tools, and instruction manuals are complete, and whether the appearance of the diesel engine has any damage such as collision.

 

       3. Inspection after diesel engine overhaul

       After the diesel engine is overhauled, in addition to the inspection and acceptance of the diesel engine according to the above-mentioned new diesel engine acceptance requirements, it is also necessary to focus on the following inspections:

       1. Whether the appearance of the diesel engine is installed correctly, and whether the relevant oil and gas circuits are tightly sealed.

       2. Pay attention to whether the relevant bolts and connecting parts are tight.

       3. During the trial operation of the diesel engine after overhaul, attention should be paid to listening, listening, modeling and viewing. Listen - whether there is any abnormal noise in the diesel engine and chassis; smell - whether there is burning smell and exhaust smoke; check whether the temperature of each part of the diesel engine is too high, the normal working temperature of the coolant should be 75-95 ℃; check the color of the exhaust, operate part is normal.
