(Summary description)1 Air combustible gas input for engine combustion The air supplied to the engine for combustion must be clean and as low as possible. Under normal circumstances, it is filtered and used around the generator through an air filter installed on the engine. However, sometimes the air near the generator is not suitable for use due to dust, heat, etc., so it must be drawn from the clean air outside the building, or when it is drawn from another room, do not remove the air filter and install it in From a distance, it is easy to get dirt into the engine by doing this. If you want to do this, you need to use an air input device approved by the factory, otherwise it will have an adverse effect on the operation of the generator. 2 Cooling and ventilation The engine, alternator and exhaust pipe all radiate heat, and the temperature rise to a certain extent will affect the efficiency of the generator. Therefore, measures must be taken to keep the engine and alternator cool. The correct air flow route is the air from the rear part of the engine, through the radiator, and then out of the outdoor through a removable exhaust pipe. If there is no exhaust pipe to exhaust the hot air outdoors, the fan will draw the hot air around, and the hot air will short-circuit back to the radiator, reducing the cooling effect. The air inlet and outlet must be large enough to allow air to enter and exit freely, and the vent is at least 1.5 times the area of ​​the radiator core. The air inlets and outlets should have shutters for protection from bad weather. These boards can be fixed, but it is best to be movable when the day is cold, so that when the machine is not turned on, the windows can be closed, which can keep the room warm and help Engine and load. For a generator that starts automatically, its shutters must also be automatically opened and closed, and it should be set to open automatically after the machine is turned on. Do not rely on radiators or heat exchange cooling systems, the heat generated by the generator still needs to be discharged outside. 3 Exhaust smoke The purpose of the engine's smoke exhaust system is to discharge smoke or odors that can cause harm to the human body to a certain height and reduce noise. A suitable muffler compatible with the exhaust pipe is used to reduce noise. It can be installed outdoors or outdoors. Warning ★ ! All generators installed indoors must use non-leakable exhaust pipes to exhaust the exhaust gas outside. The installation of the exhaust pipes must comply with relevant specifications, standards and other requirements. ! Ensure that the hot exhaust muffler and exhaust pipe are kept away from flammable materials. ! Ensure that the smoke emitted does not become a public hazard. When designing a smoke exhaust system, the most basic consideration is that the back pressure cannot exceed the allowable range, because excessive back pressure will greatly reduce the efficiency and durability of the engine, and seriously increase fuel consumption. In order to reduce the back pressure, the exhaust pipe should be designed as short as possible. If necessary, the curve must be at least 1.5 times the inner diameter of the pipe. Designs over 3m must be approved by the manufacturer. Other emission system design standards are as follows: ● Add a smoke exhaust hose to the connection between the engine exhaust outlet and the exhaust pipe. Its function is to reduce the transmission of vibration generated by the engine to the exhaust gas and the building, and allow the exhaust pipe to expand due to heat and a slight angle deviation during installation. ● Make sure that when installing the muffler and pipe, do not break or leak due to tension. ● The original parts of the exhaust system installed indoors should be insulated to reduce heat dissipation and noise. Pipes and silencers, whether installed indoors or outdoors, should be kept away from combustible substances. ● Any long horizontal or vertical exhaust pipes should be installed inclined downwards with a drain valve. The drain valve should be at the lowest point to prevent water from flowing into the engine and muffler. ● When the pipe passes through the wall, there should be sleeves to absorb shocks, and keep flammable materials away from these heating pipes, and there should be expansion pipes for the pipes to expand or contract longitudinally when heated. ● If the cut is horizontal, the end of the smoke exhaust pipe that extends outside the room should be cut to 60 degrees. If it is vertical, install a rain cap to prevent rain and snow from entering the smoke exhaust system. ● The exhaust pipe cannot be connected to another power generation exhaust pipe or other smoke pipes such as the smoke pipe of a stove or a boiler.
