Thermal runaway of the generator set may be a sign of problems within the equipment. How do we determine the cause of the thermal runaway of the generator set and identify the faulty component? For your convenience, Haixing has sorted out the common causes of thermal runaway of generator sets, as follows: 1. Oxygen recombination reaction releases heat. The oxygen recombination reaction of the oxygen produced by the positive electrode at the negative electrode is an exothermic reaction. If the heat released by this reaction cannot be released, it will increase the temperature of the battery. 2. The battery structure is not conducive to heat dissipation. The structural characteristics of valve-controlled sealed lead-acid batteries are sealing, poor electrolyte, and tight fit with ultra-fine glass fiber separators, which are not conducive to heat dissipation. That is, this battery cannot pass exhaust gas and a large amount of electrolyte like a flooded battery. And the plates are not tightly arranged to dissipate the heat in the battery. 3. The ambient temperature is high. The higher the ambient temperature, the more unfavorable it is for battery heat dissipation, and an increase in temperature will cause the battery to float.

The sound is amazing! We can identify someone by their voice. Machines are no exception, every machine has its sound. It is one sound when it is functioning normally, and another sound when it is not functioning properly. We can know whether the machine is normal through different sounds. Diesel generator sets are great machines for generating electricity. Whether it is normal or not will directly affect our lives and corporate production. According to what we have introduced, we can identify whether there is a malfunction and find the root cause of the malfunction through the sound it makes when operating. Below, Jiangsu Haixing introduces this advanced technology to you: 1. The sound emitted by the engine is continuous and regular, such as continuous knocking sounds, which may be a failure of the rotating parts. 2. The sound emitted by the diesel engine is irregular and intermittent. This requires considering that some parts of the generator are not firmly installed. 3. The sound occurs when the engine rotates

As we all know, the good operation of the overall performance of the generator set is inseparable from the effective cooperation of each component. As one of the important components of the generator set, the battery plays an important role in the operation of the entire generator set. Below, Haixing will take you Let’s learn how to properly start the generator set’s battery. 1. The generator set battery is dry when it is randomly delivered to the user, so the evenly mixed electrolyte should be injected before use. The specific operation method is: unscrew the top cover of the battery compartment, and slowly inject the electrolyte until it is between the two scale lines on the upper part of the metal sheet. After adding it, do not use it immediately. Let the battery rest for about 15 minutes. 2. When charging the battery for the first time, the charging time should not be more than 4 hours, otherwise too long charging time will damage the battery life. However, in the following circumstances, the charging time can be extended appropriately: 1. The battery storage time exceeds 3 months.

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
