If the return tube of the supercharger is blocked or damaged, the oil pressure in the middle shell will rise and the oil will flow along the seal to the compressor or turbine inlet vortex shell. If the exhaust is blocked, the turbocharger can not work effectively, so the factor of power reduction caused by exhaust resistance cannot be ignored. Any long horizontal or vertical exhaust pipe should be installed diagonally downwards and fitted with a drain valve that should be at the lowest point to prevent water from flowing into the engine and silencer. ules dry exhaust pipe is used in the exhaust system of diesel generator set, which can make full use of exhaust energy and give full play to engine performance. For this discussion, the exhaust back pressure is the gage pressure in the exhaust system at the outlet of the exhaust turbine in turbocharged engines or the pressure at the outlet of the exhaust manifold in naturally aspirated engines. Seal rings are arranged at both ends of the rotor part of the supercharger. The exhaust pipe mat not be connected to another generator set exhaust pipe or other pipe such as a stove or a boiler pipe. E. Cylinder compression force is seriously inadequate. Use the naked eye to check the inlet air cooler for cracks, perforations, or other damage to the air chamber, pipes, radiators, etc. In addition, five custom Predator diesel particulate catalysts were incorporated into the external exhaust silencers. When the pipe passes through the wall, there should be a casing for shock absorption, and the flammable material should be kept away from the heating pipe, and the expansion pipe should be left to extend or contract the pipe longitudinally. Its function is to reduce the vibration generated by the engine to the exhaust and the building, allowing the exhaust pipe to expand due to heat and a slight angular deviation during installation. The return pipe is connected to the bottom of the middle shell of the supercharger, and the oil goes back to the diesel fuel pan along the return pipe. The reason is that the piston ring is stuck in the ring groove, the piston ring has insufficient elastic force or the openings overlap, the clearance between the piston and the cylinder is too large, or the chamfer ring is incorrectly installed. The main reasons for exhausting blue smoke include the following aspects. The purpose of the diesel generator set exhaust system is to discharge the smoke or odor that can cause harm to the human body to a certain height outdoors and reduce noise. The increase of exhaust leakage and resistance will lead to the decrease of turbocharger speed, the reduction of air volume, the decrease of intake pressure, the increase of exhaust smoke and the decrease of power. The intake system of the diesel generator set is equipped with dry air filter and air filter and air resistance indicator, with exhaust gas turbocharger, full intake and guaranteed performance. A suitable silencer compatible with the exhaust pipe is used to reduce noise and it can be installed indoors or outdoors. The main role of the seal ring is to prevent exhaust and pressurized air intake supercharger in the middle shell. Besides the exhaust emission the sound emission is also important in the design of exhaust systems. Be sure not to break or leak when tightening the silencer and tube. The methods for checking the intake system of a diesel generator are as follows, When the air filter resistance exceeds the following values, the air filter element shall be replaced. The oil in the oil basin is too much oily, and too much oil is formed and splashed into the cylinder wall and burned into the combustion on chamber. Expansion joints are not allowed to eliminate misalignment between tubes. Leakage of exhaust gas usually detects leakage sound or can be seen that high temperature gas discolors the material near the leak.
