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

The operating status of the generator set is related to its quality, but it depends more on correct installation, standardized operation and daily maintenance. In order to keep the generator set in good operation and lubrication and maintenance, Haixing has compiled some lubricating and oil management matters, which will be introduced in detail below. (1) Bulk oil products 1 The containers for containers containing and storing lubricating oil must be clean; 2 Pay special attention to preventing moisture and impurities from being mixed during storage. 3 The storage period of bulk lubricating oil should not exceed six months. 4 The density of lubricating oil products is about 0.75~0.95g/cm, which is lighter than water and insoluble in water. The flash point (opening) of lubricating oil is generally higher than 150℃. It is a combustible item. Pay attention to preventing outflow from polluting the environment and ignition and combustion. 5. Indicate product name, brand, grade,

In the past decade, the development level of my country's generator set industry has been significantly improved, and the huge market demand has prompted the local enterprises to gain a foothold and develop in the domestic market. Haixing believes that after a decade of rapid development, the domestic generator set market also faces some development resistance, mainly reflected in the following three aspects: First, the growth rate of China's infrastructure investment and high-energy-consuming manufacturing industry has slowed down. The engineering projects under the 4 trillion yuan investment led by the government have been basically completed and put into operation. Some projects have not achieved good efficiency after completion, which has a resistance to the introduction of future economic stimulus policies. On the other hand, in order to reduce pollution emissions and improve industrial production energy efficiency, a large number of small and medium-sized manufacturing plants, especially enterprises in high-energy-consuming industries, face the possibility of being closed. These companies are important users of generator sets in China during the many power shortages. Secondly, the domestic market is fiercely competitive

Many times, the new generator sets that people buy back do not operate according to the requirements of the sales staff or instructions. In the initial operation, the load is small, so black smoke failure occurs. Haixing learned that a hospital user was working on the machine when starting the machine. He had to run the machine with a load when starting the machine. However, the customer did not notice that the load must be brought to the generator set more than 50%. They only brought a 20KW lighting system, and the load only accounted for 6.7% of the total load of the generator set, which did not meet the specified requirements, so black smoke was emitted. Copyright by: www.hxdlkj.com In the initial stage of use, the new diesel engine should be loaded at 50%-80% and after 60 hours of running-in, then the new machine should be run-in period. Diesel engines should not be in long-term idle operation and low-load operation during the run-in period and normal working period after the run-in period.

The climate and environment have an impact on the use effect of generator sets, so many articles have introduced how to operate units 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 occasions, the following aspects should be paid attention to when placing the unit and surrounding environment: 1. The storage of diesel generator sets should be ensured that they are not hit by objects to avoid damage. In addition, it is recommended that users place the unit in the computer room and prevent flammable and explosive items from being placed around the diesel generator set, and prepare some fire protection measures, such as placing ABC-class fire extinguishers.

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

Sometimes when people encounter overheating of the car engine, it is mostly caused by dirt in the cooling system. At this time, everyone needs to clean the cooling system. Haixing will briefly talk about the choice and specific treatment of detergents here. (1) Selection of cleaning agent types copyright by: www.hxdlkj.com When choosing cleaning agents, there are three principles for reference: ① For most precipitation and corrosion, it is better to use a slightly acidic cleaning agent. ② If the gel is not hard, you can use an alkaline or non-corrosive detergent to clean (the acidity is better, but the alkaline detergent can achieve the effect). ③ For oily impurities in the cooling system, acidic cleaning agents must be used to complete this task. Taking into account the above three principles, plus the dirt in China's domestic automobile cooling system is mainly precipitated, oily impurities and rust scale, so

Fuel is indispensable to generator sets. During operation, we must observe the amount of fuel in time. As a considerable operating cost expenditure, how can we save oil? Haixing’s staff summarized six points: 1) Maintain the optimal oil supply angle: The oil supply angle is offset, which will cause the oil supply time to be too late and the fuel consumption will increase significantly. copyright by: www.hxdlkj.com 2) Ensure that the machine does not leak oil: The treatment method is to apply valve paint to the gasket and grind it on the glass plate to smooth it, and the oil pipe joint is positive. A diesel recovery device is added, and the return oil pipe on the oil nozzle can be connected to the hollow core screws to allow the return oil to flow into the oil tank. 3) Increase the temperature of the cooling water of the diesel engine: Increased water temperature can make the diesel burn more completely, the oil viscosity will be smaller, which can reduce motion resistance and achieve fuel-saving effect. 4) Appropriately increase the pulley of the diesel engine to lower the diesel engine

The abnormal noise of the generator set may be a sign of problems within the equipment. How do we determine the source of the noise and then confirm the faulty components? Haixing has compiled several common component noise characteristics and simple reasons for easy review. copyright by: www.hxdlkj.com 1. Exhaust noise: Exhaust is a high-temperature and high-speed pulsating airflow noise. The main components of exhaust noise are as follows: low-frequency pulsating noise caused by periodic smoke exhaust, air column resonance noise in the smoke exhaust pipe, Helmholtz resonance noise in the cylinder, and noise caused by high-speed airflow passing through the valve gap and bent pipes. 2. Mechanical noise: Mechanical noise is usually caused by the sensation or impact of each other caused by the periodic changes of gas pressure and motion inertia forces during operation. 3. Burn

Recently, many netizens have consulted Haixing's staff about the acceptance of generator sets. Some people have not known what aspects to check the equipment after receiving the equipment. Below, Haixing will briefly summarize a few diesel generator set acceptance indicators, you can refer to it. copyright by: www.hxdlkj.com The following acceptance standards are for reference only when purchasing the acceptance unit: 1. The diesel consumption should comply with the specified standards; 2. The cylinder pressure and oil pressure should comply with the technical standards specified by each model; 3. After starting the diesel engine, the speed should be kept uniform when operating at idle speed, medium speed and rated speed; 4. Enough power. After the overhaul, the power of the diesel engine should be above 95% of the rated power; 5. The smoke exhaust is normal. When the diesel engine is idling, it is allowed

If your generator set equipment is not processed in time after large-scale water inlet, it will cause great damage to the equipment and accelerate the occurrence of rust and corrosion. Therefore, Haixing recommends that you understand the relevant conventional maintenance methods. 1. Rinse the surface of the diesel engine with water to remove soil and debris, and then use metal cleaning agent or washing powder to remove oil stains on the surface. 2. Push one end of the diesel engine so that the oil drain part of the oil pan is at the lowest position. Rotate the oil drain screw plug and pull out the oil ruler so that the water in the oil pan flows out by itself. When it is about to release the oil, slightly let the oil and water be released together and then rotate the oil drain screw plug. 3. Remove the air filter, remove the upper case of the filter, remove the filter element and other components, remove the water in the filter, and clean each part with metal cleaning agent or diesel. If the filter is plastic foam, wash it with washing powder or soapy water (gasoline is not allowed), then rinse it with clean water and dry it.
