Diesel generator exhaust pipe installation points, must see!

The diesel generator set will be installed in place before it is put into use, and an essential work in the installation process is the installation of the exhaust pipe of the diesel generator set. So, is there any attention paid to the installation of exhaust pipes? This is a skill you deserve
It is a very rigorous work to install the exhaust pipe of diesel generator set. Whether the exhaust pipe is installed correctly has a certain relationship with the service life of diesel generator set. The specific installation method of exhaust pipe is summarized as follows:
1. Layout of exhaust pipe of diesel generator set
1) The bellows must be connected with the exhaust outlet of the unit to absorb thermal expansion, displacement and vibration.
2) When the silencer is placed in the machine room, it can be supported from the ground according to its size and weight.
3) In the part of the smoke pipe changing direction, it is recommended to install expansion joints to offset the thermal expansion of the pipe when the unit is running.
4) The inner bending radius of the 90 degree elbow should be 3 times the diameter of the pipe.
5) The first stage silencer is as close to the unit as possible.
6) When the pipeline is long, it is recommended to install a rear stage silencer at the end.
7) The outlet of the smoke exhaust terminal should not be directly facing flammable substances or buildings.
8) The smoke outlet of the unit shall not bear heavy pressure, and all steel pipelines shall be supported and fixed by buildings or steel structures.
2. Installation of smoke pipe of diesel generator set
1) In order to prevent condensate from pouring into the unit, the flat exhaust pipe should have a slope, and the low end should be far away from the engine; A drain shall be provided on the silencer and any other part of the pipe where condensate drips, such as the vertical steering of the smoke pipe.
2) When the smoke pipe passes through the flammable roof, wall or divider, it should be insulated sleeve and wall coat plate.
3) If conditions permit, as far as possible, most of the smoke pipe is arranged outside the machine room to reduce radiant heat; Indoor smoke pipes should be equipped with insulation sheathing. If the silencer and its remaining piping must be placed indoors due to installation conditions, wrap and insulate the entire piping with 50 mm thick high-density insulation material and aluminum sheathing.
4) Thermal expansion should be allowed when the pipeline support is fixed;
5) The terminal of the smoke pipe should be able to avoid rain dripping. The horizontal plane of the smoke pipe can be extended for outlet repair or installation of rainproof cap.
