Diesel generator sets and how to deal with the reasons for Speed ??"Speed", "Speed" is the phenomenon of speed diesel generator sets and a sudden increase in the loss of control over the allowed maximum speed, accompanied by the sound of huge. When the "Speed", if not promptly take measures to control, in a short period of time can cause damage to the unit, or even personal injury, causing irreversible damage. One reason why Cummins diesel generator set to produce "speed", is due to the rotation of the plunger out of control, greater speed or stuck in the position of the largest oil, or Cummins diesel generator set with a load reduced, so that the fuel injection quantity per cycle With the movement of the plunger speed and increase the amount of increase in the fuel injection has prompted further speed increases, so the vicious cycle generator rental trailer, until more than the maximum allowed speed reached uncontrollable proportions. The following reasons: ① fuel adjustment lever (ie rack) stuck in one position. ② fuel adjustment lever with the governor connecting rod disengaged. ③ governor spring break by card. ④ governor Flyweight connecting pin stuck or prolapse. ⑤ governor Flyweight rust. ⑥ governor shaft and sliding sleeve rust or foreign objects stuck. ⑦ governor and fuel loose. ⑧ inside the governor oil viscosity is too large generator rental, making it difficult to open Flyweight. ⑨ governor axial thrust plate slide blocked. ⑩ governor Flyweight frame and guide plates slide blocked. Cummins diesel generator set exhaust how function is to install an exhaust system of the engine exhaust safely discharged to the outdoors; and exhaust, soot and noise away from buildings and crowds. Cummins diesel generator set exhaust system installation: 1, the Cummins diesel generator set installed; for absorbing thermal expansion; unit displacement and vibration; engine exhaust port should be connected to more than 36-inch retractable stainless steel bellows. 2, empathy; directly fixed on the floor of a small turbine vents should also be 18 inches above the bellows. 3, the bellows is strictly prohibited and compensation for acting as elbow pipe installation errors. 4, in order to reduce condensation corrosion; muffler exhaust pipe should be installed as close to the engine; for rapid heating. Muffler and exhaust pipe hanger bearing should be used; prohibited the use of load-bearing engine exhaust pipe. Otherwise it will damage the engine exhaust pipe; reduced turbocharger life. Black iron pipe exhaust pipe is recommended. Select the radius as some elbows. 5, in line with the engine exhaust pipe backpressure limit premise; the entire exhaust system is recommended nominal pipe diameter as consistent and engine exhaust. 6, prohibit the use of vent pipe diameter less than; more vulnerable because crude condensate pipeline corrosion; while also expanding the power loss caused by exhaust emissions. The smaller the diameter of the exhaust system changes; friction losses are smaller. All the muffler and exhaust pipe insulation from the generator rental lease implementation, to avoid accidental contact with fire or misuse start automatic fire extinguishing equipment, reduce corrosion and thermal radiation condensing unit room. Exhaust pipe and combustibles interval of at least 9 inches. You must pass through walls and ceilings should be added to the exhaust pipe or insulation sleeve cotton flame. The temperature is increased at room temperature 100 ° F, about every inch exhaust pipe expansion; 76 inches; proposal must use stainless steel bellows to absorb the thermal expansion of the long straight pipe; exhaust pipe should be laid flat slope; the lower end away from the engine; stretch outdoor or condensate collector.
