How to Maintain Diesel Generator Cylinder Block And Head

I design and manufacturing deficiencies 1. The speed and power of some improved engine are significantly higher than that of the original engine. At high speed, the inertia force and stress of the engine are also increased, and cracks are easy to appear. 2. The structure of cylinder block is complex and the wall thickness is uneven. In some weak parts, the stiffness is low and cracks are easy to appear. 3. The stress concentration will be produced at the transition of different parts of the wall thickness between the processed and the unworked parts. When these stresses are superimposed with the residual stresses in casting, cracks will also easily occur. II Improper use 1. In the cold winter, no antifreeze is used or no cooling water is released according to the specified time (cooling water is cooled to normal temperature) after shutdown, which results in the freezing of the cooling water in the water jacket, or in the cold winter, the condensation of hot water ...

Function of Diesel Generator Turbocharging

1. Improve power performance After supercharging, the circulating air flow into the cylinder increases greatly. The circulating fuel supply increases accordingly, and the power of the diesel engine increase obviously. Turbocharging can increase the power of a diesel engine by 30% or more. At the same time, due to the increase of air burst pressure, friction loss is increased, but the effective power of diesel engine is increased more, so the mechanical efficiency of diesel engine is improved. 2. Improve economic performance The increase of mechanical efficiency after supercharging reduces the fuel consumption. The increase of intake pressure not only improves the scavenging process, but also makes the pump work become positive, and the fuel consumption rate decrease. In addition, the excess air coefficient after supercharging will be increased accordingly, so that the fuel oil will become more perfect and the fuel consumption will decrease. 3. Harmful emission reduction ...

He said that Guangxi Advanced Equipment Manufacturing City (Yul...

Precautions for Reducing Noise And Heat Dissipation in Generator Room

First of all, in the design of diesel generator room noise reduction, we should consider the ventilation of the engine room. The volume of ventilation is calculated on the basis of the amount of air needed for engine combustion and the amount of air exchange required for the heat dissipation of the generator set. The sum of gas and air exchange is the ventilation of the engine room. This is a change value, which is the temperature rise of random rooms. When considering the noise reduction in the computer room, the ventilation rate of the computer room should be strictly according to the standard, that is, the temperature rise of the engine room should be controlled within 5 ℃ , and the ventilation required by the unit is the largest. Secondly, in order to calculate the cross section of the inlet and outlet air outlet according to the ventilation volume and the minimum air velocity of the exhaust muffler in the engine room. The air inlet and outlet designed accordingly can meet th...

Silent Generator Diesel Maintenance Tips

1. Low noise generator set cooling system If the cooling system is faulty, it will cause two results. 1) insufficient cooling will cause the water temperature in the generator set to be too high and shut down; 2) Water level in the water tank is lowered by the leakage of the water tank, and the unit will not operate normally. 2. Fuel system The increase in the amount of carbon deposits will affect the fuel injection volume of the injectors, resulting in insufficient diesel combustion, the amount of fuel injected into each cylinder of the engine is not uniform, which results in unstable operation of the silent generator. 3. Battery If the battery is not maintained for a long time, the electrolyte will not be supplied in time after evaporation, starting the battery charger without equipment, battery will be discharged after long-term natural discharge. 4. Engine oil The oil has a shelf life, which means that the physicochemical function of the oil will chan...

Low Voltage Diesel Generator - How to Deal With

Low voltage of diesel generator will affect the use of generator set, which is one of the common faults. This article will guide you to learn the factors that affect the voltage of generating set. 1. The unstable speed of the engine causes the unstable voltage of the generator set. 2. If the load on the generator set is too large, the voltage will be unstable. 3. The damage of the voltage regulator components of the generator causes the unit’s voltage instability. 4. The poor circulation of the fuel pipe of the genset causes the unstable speed of the engine, which causes voltage instability. We recommend you to use the following methods to check and handle the low voltage fault of diesel generator sets. 1. If the contact surface of generator brush is too small and the voltage caused by poor contact is too low, it is necessary to check whether it is caused by the commutator surface, if it is, at low speed, to polish the commutator surface with sand cloth, or t...
