1, first clear parameters and engine vibration and noise. Determines the number of cylinders of the engine noise of the order, the cylinder pressure and the exhaust valve stroke to determine the peak noise. 2, V-type engine, select the appropriate Y tube, because Y tube determines the order of the size of the generator rental prices Dongguan, the greatest impact on sound quality. 3, to determine the volume of the silencer, the silencer volume determines the insertion loss of the entire system. 4, determine the number and location of the muffler. Number muffler better, thus reducing the length of the intermediate pipe, thereby reducing the influence of standing waves. 5, consider the power loss, Dasan generator rental, power loss is an indicator of the exhaust system design, making the acoustic design, for several reasons can not start the diesel engine power loss indicator analysis must meet the prerequisites of the normal operation of the diesel engine is atomized Good accurate and timely manner diesel injected into the combustion chamber, generator rental factory in Dongguan, and the combustion chamber of compressed air to achieve a sufficient temperature to fire outbreak. To meet these two conditions, there must be a sufficiently high speed diesel engine start and when to make a certain temperature in the cylinder. When the diesel engine can not be started, it should start working, compression diesel engine fuel supply system and other aspects of the reason. 1, ambient temperature is too low: at low temperatures, the diesel engine's warm-up should be prepared to work, otherwise difficult to start. 2, starting low speed: For hand start diesel engine, it should gradually increase the speed, Dongguan, near the generator rental, then pull the handle to the non-decompression decompression position, the inner cylinder has a normal compression. If the decompression valve mechanism to adjust properly, or resisted the piston, they tend to feel the car shake very laborious. Its characteristics are a part of the crankshaft to not move on the turn, but can return to. At this time, in addition to checking decompression mechanism, we must also view the relationship between the timing gears meshing wrong. As for the use of diesel electric starter, if the speed is extremely slow start, most of the line starter weakness, does not mean that the diesel engine itself is faulty. Deal with aspects of electrical lines for detailed examination to determine whether the battery is fully charged, the wires are tight and starter connections are working properly. 3, cylinder compression force is insufficient, Dongguan factory generator rental | diesel generator (Online) | Dasan generator rental is provided by Mechanical and Electrical Equipment Co., Ltd., Dongguan Shangwang diesel. Dongguan Shangwang diesel Electrical Equipment Co. (www.dongguanfadianji.cn) is an industry leader in Dongguan, Guangdong, diesel generator sets, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
