Haixing Power Technology has created an encyclopedia of technical knowledge about generator sets. Many customers cannot understand the power definition of diesel generator sets. Therefore, our Haixing Power Technology Company will explain it to you. First of all, let’s understand the power standard of the generator set; the main power of the diesel generator set is also called continuous power or long-term power. In China, the main power is generally used to identify the diesel generator set, but internationally it is Standby power, also known as maximum power, is used to identify diesel generator sets. After observation, our Haixing Power Company found that irresponsible manufacturers in the market often use maximum power as continuous power to introduce and sell generator sets, resulting in Many users misunderstand these two concepts. Secondly, regarding the power of the generator set, Haixing Power Technology gave an example. Diesel generator sets in our country are rated by main power, that is, continuous power. The generator set can operate within 24 hours.

How to parallel the generator sets? What are the requirements and conditions for parallel operation? What are the advantages and disadvantages of parallel units? Haixing Power Technology analyzes parallel machine technology for our customers! Usually, the parallel operation of generator sets means that two generator sets are organically combined through a parallel system to achieve a theoretical increase in power generation. Two units running in parallel to generate electricity must meet three conditions: the same voltage, the same frequency, and the same initial phase. Theoretically, units of different types can operate in parallel to generate electricity as long as they have electronic speed control systems.

Many companies are helpless when facing the problem of cylinder failure of generator sets. Therefore, Gu Zhiqing, a technical expert from Haixing Power Technology Co., Ltd., came to solve the problem for the public.

Jiangsu Haixing Power Technology Co., Ltd. has been engaged in the generator set industry for many years and has detailed standards for the performance indicators of diesel generator sets. The performance of the generator set is what enterprises are most concerned about. Only generator sets with excellent performance can provide customers with a complete power supply system. 1. Appearance requirements (1) The boundary dimensions, installation dimensions and connection dimensions of the diesel generator set shall comply with the manufacturer's drawings approved by the prescribed procedures. We at Jiangsu Haixing Power think this is very important. If you don't think about it first, subsequent installation will become a big problem. (2) The welding of the unit should be firm, the welds should be uniform, and there should be no defects such as weld penetration, undercuts, slag inclusions, and pores. The welding slag and flux should be removed cleanly; the paint film should be uniform without obvious cracks and peeling; the coating should be smooth , no missing plating spots, rust, etc.; the fasteners of the unit should not be loose. (3) The electrical installation should comply with the circuit diagram, and the connection points of each wire of the unit should have obvious signs that are not easy to fall off. (4) There should be a well-grounded terminal

Recently, Haixing Power Technology Co., Ltd. communicated with many customers and found that the customers were very troubled by the noise generated by the generator set, so Haixing organized an article based on the customer's questions on how to deal with the noise in the generator room. Question: Where does the noise in the generator room come from? Answer: Jiangsu Haixing Power believes that diesel engine unit noise is a complex sound source composed of multiple sound sources. According to the mode of noise radiation, it can be divided into aerodynamic noise, surface radiation noise and electromagnetic noise. According to the cause of generation, diesel engine surface radiation noise can be divided into combustion noise and mechanical noise. Among them, aerodynamic noise is the main noise source. 1. Aerodynamic noise is caused by the unsteady process of gas, that is, by the disturbance of gas and the interaction between gas and objects. Aerodynamic noise radiated directly to the atmosphere, including intake noise, exhaust noise and cooling fan noise. 2. Combustion noise and mechanical noise

Haixing Power Technology reminds buyers that when purchasing a diesel generator set, they need to analyze many aspects of the unit in order to choose a satisfactory product with excellent performance and environmental suitability. As a professional manufacturer, Haixing Power Technology Co., Ltd. does not regard profit as its foundation. It has a responsible and serious attitude towards customers and helps customers choose the most suitable products. Jiangsu Haixing Power believes that the main factors that should be considered when purchasing a diesel generator set include mechanical and electrical performance, purpose of the unit, load capacity and change range, automation functions, etc. (1) Purpose. Because diesel generator sets can be used in three situations: regular use, backup and emergency. Therefore, different uses have different requirements for diesel generator sets. When purchasing a communication generator set, you must meet the requirements of G3 or G4 in GB2820-1997, as well as the 24 performance index requirements specified in the 'Implementation Rules for Network Quality Certification and Inspection of Communication Diesel Generators'.

Recently, it was reported that many elderly people in the community reported that the generator set was rumbling every day, the windows could not be opened, and the black smoke was choking and making people cough. The reason is that due to the construction of a power plant near a certain community, the black smoke and noise from the diesel generator sets have caused a lot of trouble to the residents of the community. Haixing Power Technology technicians analyzed that: On the one hand, it may be a problem with the quality of the power generation unit itself, which did not meet relevant pollutant and noise emission standards. Haixing recommends repairing or eliminating diesel generator sets that have quality problems as soon as possible; on the other hand, it may be caused by black smoke or noise caused by a failure of the diesel generator set during use. Smoke from the generator set is generally produced when the diesel engine is under heavy load, such as when accelerating, climbing or overloading. It may also be a product of combustion. Under heavy load of the diesel engine, the temperature of the combustion chamber is high and too much fuel is injected. , the mixture is formed unevenly, there is insufficient air during combustion in local areas, and the fuel burns at high

Generator sets used outdoors often encounter rainy weather. If protective measures are not taken, the generator set can easily get caught in the rain. If it is not repaired and cared for in time, it will soon be rusted, corroded, and damaged. Appropriate maintenance methods can be selected according to the degree of rain exposure of the unit. Jiangsu Haixing Power Technology Co., Ltd. summarized the 'Maintenance Measures for Outdoor Generator Sets after Rain' to help customers solve problems. 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 drained slightly. Let some of the oil and water drain out together and then tighten the oil drain plug. 3. Remove the air filter of the generator set, remove the filter upper shell, take out the filter element and other components, remove the water in the filter, and use metal cleaning agent or diesel

Butter (lubricating oil) is widely used in diesel engines. It can protect the engine body, but it cannot be abused, otherwise it will have adverse consequences and even be counterproductive and damage the engine body. Butter can lubricate and prevent corrosion, but Haixing Power Technology Co., Ltd. is here to tell you that some parts of the diesel generator set are not suitable for coating with butter. 1. Applying butter to the dry cylinder liner of the diesel generator set will cause the diesel engine to overheat and affect normal operation. The reason is that when the engine heats up to normal temperature, the cylinder liner will expand due to heat, and the cylinder seat hole will have a lower temperature due to the action of cooling water, so the expansion will be smaller. The outer surface of the dry cylinder liner is close to the seat hole to conduct heat dissipation. Grease on the surface of the cylinder liner prevents good contact between the two surfaces and prevents normal heat dissipation. 2. Apply butter to the cylinder head and cylinder gasket to enhance sealing. After the cylinder head nut is tightened, part of the butter will be squeezed out of the cylinder and wasted, and part of the butter will be squeezed into the cylinder. when diesel engine

Similar to human bone joints, the 'piston rings' of the generator set are divided into gas rings and oil rings according to their functions. They have the following functions.Piston rings are the parts that move in three directions among all engine parts.(i.e. axial movement, radial movement and rotational movement in the circumferential direction), and it is also the most demanding part in use conditions.At the moment of explosion in the engine combustion chamber, the gas temperature can reach 2000℃-2500℃, and its explosion pressure reaches an average of 50kg/cm2. The temperature of the piston head is generally not lower than 200℃.The piston makes reciprocating motion, and its speed and load are very large.Therefore, piston rings work under high temperature and high pressure conditions.Especially the first gas ring has the highest temperature and the worst lubrication conditions. In order to ensure that it has the same or higher durability as the other rings, the working surface of the first gas ring is often porous chrome plated. deal with.The porous chromium plating layer has high hardness and can store a small amount of lubrication.
