The exhaust system of the generator set should minimize the number of elbows and shorten the total length of the exhaust pipe, otherwise the exhaust pipe pressure of the generator set will increase. The unit produces excessive power loss, which affects the normal operation of the unit and reduces the normal service life of the unit. The exhaust pipe diameter specified in the technical data of the diesel generator set is generally based on the installation of a total exhaust pipe length of 6m and a maximum of one elbow and one muffler.
When the actual installation of the exhaust system has exceeded the specified length and number of elbows, the diameter of the exhaust pipe should be appropriately increased, and the increase depends on the total length of the exhaust pipe and the number of elbows. The first section of piping from the unit supercharger exhaust manifold must contain a flexible bellows section. The bellows has been supplied to the customer at random. The second section of the exhaust pipe should be elastically supported to avoid unreasonable installation of the exhaust pipe, or additional lateral stress and When compressive stress is added to the unit, all supporting mechanisms and suspension devices of the exhaust pipe should have certain elasticity.
When there is more than one unit in the machine room, remember that the exhaust system of each unit should be designed and installed independently. Never allow different units to share an exhaust pipe to avoid abnormal movement caused by different exhaust pressures of different units during operation, increase the exhaust pressure and prevent the backflow of waste smoke and exhaust gas through the shared pipe. The normal power output of the unit may even cause damage to the unit.
