What is the rated power of domestic generator sets? Many customers may not understand this concept. In fact, it means that the maximum power allowed by the diesel engine is limited by the mechanical load and thermal load of the parts. Therefore, it is necessary to specify the maximum power allowed for continuous operation, which is called the calibrated power. According to national standards, the calibrated power on the generator nameplate is divided into the following four categories. Haixing will introduce them one by one here. 1) 15min power: that is, the maximum power that the generator set is allowed to run for 15 minutes. Calibrated power that may be overloaded in a short period of time and requires acceleration performance, such as the calibrated power of generator sets such as automobiles and motorcycles. 2) 1h power: that is, the maximum effective power that the generator set is allowed to run continuously for 1 hour. Such as the calibrated power of generator sets such as wheeled tractors, locomotives, ships, etc. 3) 12h power: that is, the maximum effective power of the generator set allowed to run continuously for 12 hours

The operating status of the generator set has a corresponding relationship with its quality, but it relies more on correct installation, standardized operation and daily maintenance. In order to keep the generator set in good operating condition, lubrication and maintenance are the top priority. Haixing has compiled some management matters related to lubricating oil, which are introduced in detail below. (1) Bulk oil products 1. Containers for holding and storing lubricating oil must be clean; 2. Special attention must be paid to preventing the mixing of water and impurities during storage. 3 The storage period of bulk lubricating oil should generally not exceed half a year. 4 The density of lubricating oil is about 0.75~0.95g/cm. It is lighter than water and insoluble in water. The flash point (opening) of lubricating oil is generally higher than 150 ℃. It is a flammable item. Care should be taken to prevent it from flowing out and polluting the environment. Burn on fire. 5 Indicate the product name, brand number, grade,

In the past ten years, the development level of my country's generator set industry has been significantly improved, and huge market demand has prompted local companies to gain a foothold and develop in the domestic market. Haixing believes that after ten years of rapid development, domestically produced The generator set market is also facing some development resistance, mainly in the following three aspects: First, the growth rate of China's infrastructure investment and high energy-consuming manufacturing industry has slowed down. The 4 trillion yuan investment projects led by the government have been basically completed and put into operation. Some projects have not been used very efficiently after completion, which will hinder the introduction of future economic stimulus policies. On the other hand, in order to reduce pollution emissions and improve the energy efficiency of industrial production, a large number of small and medium-sized manufacturing plants, especially companies in high-energy-consuming industries, face the possibility of being closed. These companies were important users of generating units during China's multiple power shortages. Secondly, competition in the domestic market is fierce

Many times, the new generator sets that people buy are not operated according to the requirements of the salesperson or the instructions. The load is small in the initial operation, so black smoke faults occur. Haixing learned that a hospital user started the unit for maintenance. When starting the unit for maintenance, the unit must be operated with load. However, the customer did not notice that the load must be brought to more than 50% of the full load of the generator set. They only brought The load of the 20KW lighting system only accounted for 6.7% of the total load of the generator set, which did not meet the specified requirements, so black smoke emitted. Copyright by: www.hxdlkj.com In the initial stage of use, a new diesel engine should be run in at a load of 50%-80% for 60 hours before it can pass the running-in period of the new engine. During the running-in period and the normal operating period after the running-in period, the diesel engine should not be idle for a long time or run at low load.

Climate and environment have an impact on the performance of the generator set. Therefore, many articles have introduced how to operate the unit in different climates. What if it is in a relatively closed room? What are the environmental requirements for indoor unit operation? Haixing believes that in relatively closed situations, the following aspects should be paid attention to when placing the unit and its surrounding environment: 1. The diesel generator set should be stored to ensure that it is not hit by objects to avoid damage. In addition, it is also recommended that users place the unit in the machine room, prevent flammable and explosive items from being placed around the diesel generator set, and prepare some fire-fighting measures, such as placing ABC class fire extinguishers.

In order to prevent moisture from entering the surroundings of the alternator set and minimize moisture condensation, so as not to reduce the insulation performance of the generator or even affect the

Sometimes we encounter car engine overheating, which is mostly caused by dirt in the cooling system. At this time, we need to clean the cooling system. Haixing will briefly talk about the selection of detergents and specific treatments. (1) Selection of cleaning agent types Copyright by: www.hxdlkj.com When selecting cleaning agents, there are three principles for reference: ① For most precipitation and corrosion, slightly acidic cleaning agents are more effective. ② If the gel is not hard, it can be cleaned with alkaline or non-corrosive detergent (acidic is better, but alkaline detergent can achieve the effect). ③For oily impurities in the cooling system, acidic cleaning agents should be used to complete this task. Considering the above three principles comprehensively, plus the fact that the dirt in China's domestic automobile cooling systems is mainly sediment, oily impurities and rust, it makes

Fuel is indispensable for the generator set. During operation, we must observe the amount of fuel in time. As a large operating cost, how can we save fuel? Haixing staff summarized six points: 1) Maintain the optimal fuel supply angle: If the fuel supply angle deviates, the fuel supply time will be too late and fuel consumption will increase significantly. copyright by: www.hxdlkj.com 2) Ensure that the machine does not leak oil: The solution is to apply valve paint on the gasket and put it on the glass plate to smooth it, and align the oil pipe joint. Add a diesel recovery device and use a plastic pipe to connect the oil return pipe on the oil nozzle to the hollow screw to allow the return oil to flow into the fuel tank. 3) Increase the temperature of the cooling water of the diesel engine: Increasing the water temperature can make the diesel burn more completely, the viscosity of the engine oil will be smaller, which can reduce the movement resistance and achieve fuel saving effect. 4) Appropriately increase the diesel engine pulley, and lower the diesel engine

Abnormal noise from the generator set may be a sign of problems within the equipment. How do we determine the source of the noise and identify the faulty component? Haixing has sorted out the characteristics and simple causes of several common component noises for your convenience. copyright by: www.hxdlkj.com 1. Exhaust noise: Exhaust is a high-temperature, high-speed pulsating airflow noise. The main components of exhaust noise are as follows: low-frequency pulsating noise caused by periodic exhaust smoke, The gas column resonance noise in the exhaust pipe, the Helmholtz resonance noise of the cylinder, and the noise generated when the high-speed airflow passes through the valve gap and curved pipes. 2. Mechanical noise: Generally speaking, mechanical noise is mainly caused by the vibration or mutual impact of the moving parts of the engine caused by the periodic changes in gas pressure and motion inertia force during operation. 3. Burn

Recently, many netizens have consulted the staff of Haixing about the acceptance of generator sets. Some people purchased generator sets and did not know where to inspect the equipment after receiving the equipment. Below, Haixing will briefly summarize a few diesel generator set acceptance indicators for your reference. copyright by: www.hxdlkj.com The following acceptance standards are only for your reference when accepting the unit after purchase: 1. Diesel consumption should comply with the specified standards; 2. Cylinder pressure and oil pressure should comply with the regulations of each model. technical standards; 3. After starting the diesel engine, the speed should be kept uniform when running at idle speed, medium speed and rated speed; 4. Sufficient power. After overhaul, the power of the diesel engine should be above 95% of the rated power; 5. Smoke exhaust is normal. When the diesel engine is idling, it is allowed

If our generator equipment is not treated in time after large-scale water intrusion, it will cause great damage to the equipment and accelerate the occurrence of rust and corrosion. Therefore, Haixing recommends that you understand the relevant routine maintenance methods. 1． Rinse the surface of the diesel engine with water to remove dirt and debris, and then use metal cleaner or washing powder to remove oil stains on the surface. 2． Support one end of the diesel engine so that the oil drain part of the oil pan is at the lowest position. Unscrew the oil drain plug and pull out the oil dipstick to allow the water in the oil pan to flow out on its own. When it reaches the point where the oil is about to be drained, the oil should be allowed to drain slightly. Drain some of it together with water and screw on the oil drain plug. 3. Remove the air filter, remove the filter upper shell, take out the filter element and other components, remove the water in the filter, and clean the parts with metal cleaner or diesel. The filter piece is made of plastic foam. It should be washed with washing powder or soapy water (gasoline is prohibited), then rinsed with clean water and dried.
