The diesel generator set has some skills for analyzing the abnormal water temperature. When operating the diesel generator set, the employee loves to adjust the outlet temperature to a very low temperature. They feel that the water temperature is low, and no cavitation signs will appear in the pump, and the cooling water (liquid) will not. Intermittent, there is insurance factor in use.
The original water temperature will not cause cavitation unless the temperature is first 95 ° C, and the cooling water (liquid) will not be interrupted. On the contrary, if the water temperature is too low, it will be very unhelpful to the employment of diesel engines. If the water temperature is too low, it will lead to the following three crises.
① The temperature is low, the premise of diesel point in the cylinder is deteriorated, the period after the fire is prolonged, the employment of the engine is prone to brutality, the damage of crankshaft bearings, piston rings and other components is increased, the power is reduced, and the economy is reduced.
② It is easy to condense the water and gas on the wall of the cylinder after the tapping, and the metal will be corroded.
③ It is a bit of diesel and maybe controlled release motor oil, which makes the smooth situation worse.
④ It is the material point that is not full and becomes gelatinous, which causes the piston ring to be trapped in the piston ring groove, the valve is stuck, and the pressure in the cylinder decreases when the contraction ends.
⑤ The water temperature is too low, the oil temperature is also low, the oil becomes thicker, the fluidity becomes worse, and the oil supply is insufficient, the gap of the crankshaft bearing is reduced, and the smoothness is poor.
How much water temperature is usually suitable for diesel generators?
In winter, the temperature is low, the temperature of the diesel generator set is low, and the temperature of the coolant will be very low. Therefore, the temperature of the diesel generator's coolant will also go up a little bit. When the diesel engine displays useful power, the temperature of the coolant should be around 80 °. When using a diesel generator set in winter, it is better to ensure that the water temperature is around 80 ° when transmitting power to run the load.
The summer temperature was higher, and this year the summer temperature was more abnormal. Some tropics reach 44.5 °. Cooling fluids for diesel generator sets go up quickly in such a tropical season. The diesel engine simply becomes a pull-cylinder incident in the 100 ° water temperature tropical zone, so the diesel generator set should stop working or reduce the load when the coolant preempts up to 95 °.
