No.
Many diesel generator operators do not want the diesel generator to operate at the rated speed, thinking that a lower speed will not cause a breakdown. In fact, too low a speed will cause adverse consequences:
< p>(1) Too low a rotation speed will reduce the power output of the diesel engine and at the same time reduce its dynamic performance, the rotation speed of the binding mechanism will also be reduced, which will affect the performance of; working machinery, such as reducing water flow of water pump, reducing head of water pump, etc.(2) Due to the low speed, the injection pressure is reduced, resulting in poor diesel atomization, incomplete combustion of the mixture and carbon deposits. Carbon deposits can easily clog the fuel injector nozzle ports, causing a decreaseof the power of the diesel engine and the emission of black smoke from the exhaust pipe. Excessive carbon deposits can sometimes clog exhaust mufflers, turbochargers and other parts, preventing the diesel engine from functioning properly.
(3) When the generator runs at low speed for a long time, the oil pressure decreases, the oil circulation speed slows down, the cleaning capacity decreases, the sealing effects and cooling deteriorate and the amount of lubricating oil received by splash lubricated parts Reduces, worsens the wear of the surface of moving parts and reduces the service life. For example, the wear between the piston, piston ring and cylinder wall increases, the wear of the valve train transmission parts increases, the life of the main bearing and connecting rod bearing decreases, etc.
(4) The reserve power of the worddiesel engine is reduced, causing the diesel engine that should be operating normally to be at full load or overload.
