The 100-kilowatt farming industry biogas generator will be placed for a long time when not in use. After being placed incorrectly for a long time, it is prone to failure after restarting. Then the precautions for long-term placement of the biogas engine are as follows:
1. Add a small amount of water and engine oil to the intake port, roll the car to attach it to the top of the piston, the inner wall of the cylinder liner and the valve sealing surface, and place the valve in a closed state to separate the cylinder liner from the outside world.
2. When it is determined that the biogas engine will not be used for a long time, we should try to drain the cooling water and lubricating oil. Let the biogas generator set clean.
3. Cover the air filter, exhaust pipe and fuel tank to prevent dust from falling into it.
4. It is necessary to ensure that the biogas engine unit is clean. Remove dust and oil on the surface.
5. Remove the valve cover of the 100-kilowatt farming industry biogas generator, dip a small amount of anhydrous engine oil with a brush, and brush it on the rocker arm and wait until the parts.
6. The biogas engine should be placed in a well-ventilated, dry and clean place. Precautions for the use of coolant for biogas generators in the 100-kilowatt aquaculture industry
1. The role of the coolant for the biogas generator in the 100-kilowatt farming industry
The normal working temperature of a biogas generator in the 100-kilowatt farming industry is 65-70°, which is 15-20° lower than that of ordinary engines. Excessive engine temperature will cause the mixed gas to deflagrate, affect the normal operation of the engine and accelerate the engine oil degeneration. It produces carbon deposits, easy to form oil film breaks, poor lubrication, and aggravated wear. Therefore, it is particularly important to use the engine coolant to properly cool down the biogas engine, which can ensure the normal operation of the engine.
However, if the temperature of the engine is too low and the cooling is too much, it will also produce a counterproductive effect, which will increase the heat loss of the engine cover, which is not conducive to the formation and extinguishment of combustible mixed gas, and will cause the oil viscosity of the biogas generator in the 100-kilowatt farming industry to increase and friction The loss increases, resulting in a decrease in the effective power of the engine.
In the process of practical application, the small circulation and large circulation of the common coolant are used to deal with the smooth cooling problem of the biogas engine, so that the engine can be properly cooled, so that it can work within a suitable temperature range. Generally, with regard to the water cooling system of the biogas engine, when the coolant temperature in the cooling water jacket of the cylinder head reaches about 60°, the large cycle starts, which can ensure the normal operation of the biogas engine.
2. Can the water medium replace the engine coolant?
In practice, users often neglect the use of engine coolant, and simply use water as the cooling medium for the generator set. With the serious loss of cooling water in the operation of the generator set, frequent replenishment of water is required, and scaling will occur after a period of use, causing the cooling effect of the 100-kilowatt farming industry biogas generator to drop, and the engine operating temperature increases, which affects the normal operation of the generator set Power generation.
