Do not let the gas generator run at low temperature, because it will reduce the service life of the machine. What is the principle? Today, the manufacturer of gas generator sets will explain why the generator will "reduce its life" under low temperature operation.
When the gas generator works at low temperature, the cooling water takes away a lot of heat energy from the cylinder, which increases its heat loss; The mixture can not form and burn well, and the fuel consumption will increase by 8%~10%; After entering the cylinder, droplets of fuel will wash the lubricating oil film on the cylinder wall and penetrate into the crankcase, increasing the wear of parts, diluting the lubricating oil in the oil pan, increasing fuel consumption and reducing power output.
Some parts subject to thermal expansion are not expanded to the proper size due to low temperature, which affects the working performance of the whole machine, for example, the clearance between piston and cylinder is too large, and the sealing is not good;
The valve clearance is too large to be impacted by the rocker arm, which makes it difficult to start the gas generator. When the diesel engine is working, the high temperature of the compressed gas is a necessary condition to ensure the ignition of the fuel. When the temperature of the cylinder, piston and other parts decreases, the temperature at the end of the compression will drop, the ignition will be delayed and the combustion conditions will deteriorate, resulting in incomplete fuel combustion, rough operation of the gas generator and smoke exhaust.
When the temperature of the cooling water in the water tank is too low, the temperature of the lubricating oil will drop. When the temperature is low, the viscosity of the oil will be higher, and its fluidity will become worse. This will not only increase the wear of the parts of the gas generator set, but also increase the mechanical power loss due to the increase of the movement resistance of the parts, and the output power of the gas generator set will decrease.
Therefore, when the gas generator is operating in a very cold climate, it is necessary to add auxiliary starting equipment, such as fuel heater, oil heater, water jacket heater, etc. The fuel heater or electric heater is used to heat the cooling water and fuel lubricating oil of the cold engine, so that the whole engine can be heated up, so that it can be started smoothly. When the temperature of the engine room is not lower than 4 ° c, install the coolant heater to keep the temperature of the engine block above 32 ° c.
