How To Adjust The Components Of Diesel Generator Set

Jul. 22, 2021

In recent years, as a backup power source and emergency power source, diesel generator sets have been widely used in more and more fields such as banks, airports, schools, hospitals, communities, factories, construction sites, etc. When using them, users should learn how to adjust several parts of the diesel generator set, and quickly learn about it with Jiangsu Starlight Electricity Equipments Co.,Ltd.


1. Adjustment of oil pressure

There are generally two lubrication methods for diesel generator sets: pressure lubrication and splash lubrication. Too low or too high oil pressure will affect the lubrication quality of diesel generator sets. Therefore, the diesel generator set must control the oil pressure within the specified range during operation.


2.The adjustment of the regulator

During the use of diesel generator sets, faults such as the pointer of the charging current meter do not move, and the charging current is too large or too small. If the charging current to the battery is too large, the service life of the battery will be shortened; if it is too small, the battery cannot be charged on time. When the diesel generator set is working, if the charging current displayed by the charging ammeter is too large, the current limiting spring of the regulator should be adjusted to shorten the spring, then the current will decrease, otherwise the current will increase. Be careful not to apply too much force during the adjustment process, and lightly touch it until it meets the requirements.

3.Adjustment of valve clearance

When replacing the cylinder head gasket and piston ring of a diesel generator set or tightening the cylinder head according to the specified torque due to the cylinder head gasket leakage, the valve clearance must be adjusted. Because the valve clearance is too large, the valve opens and closes late (normally, the intake valve opens early and the exhaust valve closes late), insufficient intake air, poor exhaust and excessive diesel exhaust noise, etc.; and excessive valve clearance If it is too small, it will cause the valve to close tightly, ablation or air leakage, etc.


4.The adjustment of the fan belt

If the fan belt of diesel generator set is too tight, it will increase the wear of the bearings of the direct alternator, water pump, and fan. If the belt is too loose, it will cause insufficient fan air volume and affect the cooling effect of the cooling water. At the same time, the output voltage of the generator decreases and the flow rate of the water pump decreases, which cannot meet the requirements. Therefore, the fan belt must be adjusted according to the requirements of use.


5. Adjustment of fuel supply advance angle

In order to obtain the most economical fuel consumption rate, after the diesel generator set has been running for 500 hours or when the fuel injection pump-regulator assembly is calibrated and reassembled, the fuel supply advance angle is generally corrected.


6. Decompression adjustment of diesel engine

During the use of diesel generator sets, it is often difficult to start due to the influence of weather or insufficient battery power. At this time, the operator can reduce the compression ratio by decompressing the intake valve of the diesel engine, improve the starting resistance, and start the diesel generator set.


The above are the parts that need to be adjusted during the use of diesel generator sets. I hope it will be helpful to you.
