After the installation of the Industrial generator set, regular maintenance is also important. After the long-term use of the marine generator set, there are problems of low speed and unstable speed. How should we solve them? Hosem Power gives you the following suggestions:   Failure of occurrence: The speed of generator set is low or unstable   Possible reasons for this issue: 1. The fuel filter is clogged 2. The fuel system is not working properly 3. The governor is not working properly 4. The ambient temperature is low or not preheated 5. The AVR/DVR does not work properly 6. The engine speed is too low   Treatment method: 1. Replace the fuel filter 2. Check the engine preheating system, run the engine no load and bring it up to operating temperature 3. Check engine governor   If you have other questions, please call us, Phone/ Wechat/ WhatsApp: 008613205904365  

Malfunction that occurred: The generator could not start   Cause (Circuit Aspect)： The circuit is not working properly Insufficient battery power The battery connector is corroded or the cable connection is loose The cable is improperly connected or the charger or battery is faulty Starting motor failure The starting circuit of the control panel is faulty Other possible faults   Treatment method: Check the circuit Charge the battery and replace it if necessary Check cable terminals, tighten nuts, replace corroded connectors and nuts Check the connection between the charger and the battery Check the start/stop control circuit of the control panel   Cause (Engine Aspact): There is not enough fuel in the engine cylinder There is air in the fuel line The fuel filter is clogged The fuel system is not working properly The air filter is clogged Low ambient temperature The governor is not working properly   Treatment method: Check the fuel tank and fill it up Eliminate air ...

  It is strictly prohibited to start diesel engine with load. Before starting the diesel generator set, note that the output air switch of the generator must be in the open state. After starting a normal diesel engine, it needs to run at idle speed for 3-5 minutes (about 700 RPM). The temperature in Winter is low, idle time should be appropriately extended to a few minutes. After the diesel engine starts, it is necessary to observe whether the oil pressure is normal, whether there is oil leakage, water leakage, and other abnormal phenomena.   If there is no abnormal phenomenon, increase the diesel engine speed to the rated speed of 1500 RPM. At this time, the generator display frequency is 50HZ, the voltage is 400V, and the output air switch can be closed and put into use. The diesel generator set is not allowed to run for a long time without load. (Because long-term no-load operation will make the diesel fuel injector can not be completely burned, resulting in carbon deposit...

Although the diesel generator set is a relatively high-grade diesel generator set, but in the process of use often appear suddenly serious damage, so it is essential to install protective devices on the diesel generator set. Many users are reluctant to do this kind of protection because it saves money. In fact, protection measures are installed to protect diesel generator sets from excessive losses in unexpected situations. Hosem Power gives a few examples:   1, when the engine oil pipe burst and lack of oil, the oil pressure protection system starts to work, the diesel generator set immediately shut down.   2. When the engine oil supply system fails, the engine overspeed protection system starts to work, and immediately pull the oil breaker to stop the engine.   3. When the oil temperature and water temperature exceed the limit temperature, the temperature system starts to work, so that the engine stops.   When the diesel generator set engine occurs the above fault...

Fuel consumption is an important index to measure the performance of Genset, in our daily use, there are ways to reduce fuel consumption:   1.To make reasonable use of the Industrial generator set, it must first be used within the rated power range. Overloaded use will definitely increase the operating burden of the generator set and reduce the service life of the equipment. Unit damage, with the increase of the number of use, fuel consumption is bound to be higher   2. before the generator set is used, two layers of silk cloth can be added to the filter screen of the oil supply system to improve the combustion rate by reducing impurities in the oil, so as to reduce fuel consumption, or two layers of oil can be carried out first. Wait for four days to settle, then use   3. the generator set is usually cooled by air cooling and water cooling system during operation, but if the temperature is too low when starting, it will reduce the viscosity of oil and reduce the movemen...

Due to the complex structure of the diesel generator set, many users buy the diesel generator set, but do not know how to operate it and maintain it, the following will introduce some precaution for ensuring good operation of Hosem Power diesel generator set:   What happens if the diesel generator is overloaded for a long time?   Genset usually cannot be overloaded when operating but can withstand short-term overloads. If the unit overload time is too long (exceed Overrated power) something can happen. Include: Overheating of cooling system Generator winding overheating Low oil pressure due to decomposition of lubricating oil concentration Unit life is shortened   What happens if the unit load is too low?   If the unit is operated at low load for a long time, the water temperature can not rise to the normal temperature, the viscosity of oil is large, and the friction becomes larger. The oil that should be burning in the cylinder is heated, causing paint to form on t...

How to identify the authenticity of the Cummins engine:   Cummins is the largest foreign engine investment enterprise in China. Its NTA855 series and K19 series engines are loved by people because of their reliable and durable quality. However, with the wide use of Cummins engines in the world, some fakes of Cummins engines also appear. In the market, how to effectively distinguish whether the engine is genuine? Hosem Power provides you with several methods Appearance: For professionals who are familiar with the engine, the authenticity of the engine can be identified by the appearance, color, and overall color difference of the engine. Identification of the logo: There are logo stickers of the corresponding brand on the body of the diesel engine. Nameplate identification: The nameplate on the engine is marked with the engine number, and there are corresponding codes on the cylinder block and oil pump. Call the original factory to confirm the code, and then you can know the authen...
