By paying more attention to detail, combustion failures of small diesel engines can be avoided. Starting from the common working point of various types of diesel generator sets, the methods to prevent the combustion failure of small diesel engines are summarized.
1. Pay attention to hygiene. When a small diesel engine is running, if dust, water stains and other debris get inside it, a short-circuit medium will be formed, which will damage the wire insulation, cause an inter-turn short circuit, increase the current and increase the current. Therefore, prevent dust, water stains, and other debris from entering the small diesel engine. At the same time, the exterior of the small diesel engine should be cleaned frequently. Do not place dust and other debris in the radiator of a small diesel engine to ensure diesel power generation. The heat dissipation condition of the device is good.
2. Observe and listen. Observe whether the small diesel engine has vibration, noise and peculiar smell, and then operate the small diesel engine, especially the high-power small diesel engine, you need to frequently check whether the anchor bolts, end covers, bearing glands, etc. are loose, and whether the grounding device is reliable. If the generator is found to have increased vibration, increased noise, and produced odors, it must be turned off as soon as possible to pinpoint the cause and troubleshoot.
3. Current hold. Small diesel engines can be overloaded due to overload, low pressure, or mechanical blockage of the drive. Therefore, in the operation of small diesel engines, it is necessary to pay attention to check whether the transmission device is flexible and reliable; whether the concentricity of the coupling is standard; Flexibility of the gear drive, etc., if there is any jamming, it should be shut down and run again immediately after troubleshooting.
4. Regular inspection and maintenance. The technical condition of the control equipment of the small diesel engine plays a decisive role in the normal start of the small diesel engine. Therefore, the control equipment of a small diesel engine should be placed in a dry, ventilated and easily operated location, and dust should be removed regularly. Always check whether the contactor contacts, coil cores, terminal screws, etc. are reliable, and whether the mechanical parts are flexible to maintain good technical condition to ensure that the small diesel engine works properly and is not burned.
It can be seen that doing a good job of detail is the key to preventing combustion. At the same time, we should also pay attention to the signs of combustion failure corresponding to combustion failure and its causes, and increase the degree of standardization of use and maintenance to avoid the failure and burnout of small diesel engines to a large extent.
