Popular Science丨6 common sense about diesel generator sets

1. The influence of different climatic environments on the operation of diesel generator sets:
Rain, dust and sandstorms, salt water and fog from the seashore, corrosive gases such as sulphur dioxide in the air.
2. Composition of diesel generator set:
Diesel engines, generators, controllers. Other components: base, base fuel tank, radiator, water tank, recoil pad, soundproof box, silencer, silent box and other components.

3. Introduction to noise level:
30~40 dB is an ideal quiet environment. Anything above 50 decibels can affect sleep and rest. Above 70 decibels can interfere with conversation and affect work efficiency. Living in a noise environment above 90 decibels for a long time can seriously affect hearing and cause neurasthenia, headaches, increased blood pressure and other diseases. If suddenly exposed to noise up to 150 decibels, the auditory organs can be traumatized, causing the eardrum to rupture and hemorrhage, and the hearing in both ears is completely lost. In order to protect hearing, noise should be controlled not to exceed 90 decibels; In order to ensure work and study, the noise should be controlled not to exceed 70 decibels, and in order to ensure rest and sleep, the noise should be controlled not to exceed 50 decibels.
4. The purpose of parallel operation of diesel generator sets:
Expand power supply capacity
Improve the reliability of power supply and achieve uninterrupted power supply.
5. Fuel consumption calculation:
Fuel consumption (L/h) = Diesel engine rated power (kw) X fuel consumption rate (g/kwh) / 1000 / 0.84 (the density of diesel 0# is 0.84kg/L)
6. What will happen if the diesel generator team leader is overloaded.
The unit is usually not allowed to be overloaded, but it can withstand short-term overloads. If the unit is overloaded for too long (more than the rated power), some conditions may occur.
Including: overheating of the cooling system, overheating of generator windings, low oil pressure caused by decomposition of lubricating oil concentration, and shortening of unit life.
