    Haixing Power analyzes the principles of fault handling of generator sets
    Many customers are very concerned about the fault handling of generator sets during their consultations. Haixing Power's technicians will talk to you about the principles of fault handling. With these principles as the focus, they can reasonably carry out the fault handling of generator sets so that the normal operation of the equipment can be restored as soon as possible. 1. The judgment of faults should be analyzed from an overall perspective, and the troubleshooting must be comprehensive. The systems, components and parts of a diesel generator set are closely related. If a component, system or part fails, other systems, components or parts will inevitably be involved. Therefore, a fault phenomenon cannot be viewed in isolation. We must analyze the overall situation of the fault and troubleshoot it in a timely manner. 2. When looking for a failure of the diesel generator set, it should be disassembled as much as possible. When troubleshooting, you cannot blindly disassemble the components of the diesel generator set. You must first understand the structure, working principle, faulty parts, etc. of the diesel generator electronic components before disassembly. Only in

    In the cold winter, don’t forget to prepare antifreeze for the generator set!
    Ambient temperature has an impact on the use of generator sets. Now it is gradually entering the cold season. Haixing Power reminds everyone: prepare antifreeze in advance and add antifreeze in time! Antifreeze is of great significance to the operation of generator sets 1. Antifreeze When the indoor and outdoor temperature is too low in winter, in order to ensure that the cooling system of the diesel generator is not frozen, generally speaking, the antifreeze temperature of the commonly used generator antifreeze is between minus 20 degrees Celsius and above 45 degrees Celsius. It is often reasonably selected according to the actual needs of different regions to meet the requirements of Cummins generators. 2. Anti-boiling diesel generators ensure that they will not boil prematurely at high temperatures. Generally, the boiling point of the commonly used antifreeze is between 104 and 108 degrees, and when the antifreeze is added to the cooling system and pressure is generated, the boiling point will be higher. 3. The special antifreeze for anticorrosion generator sets can reduce corrosion on the generator cooling system, thereby reducing the rust of the cooling system.

    Analysis of the problem of fast and slow operation of generator sets
    The generator set has a long and regular period of time and is sometimes fast and sometimes slow in the low and medium speed range, which is the result of excessive speed regulation reaction lags behind the actual speed changes. The main reasons are as follows. The internal lever of the speed regulator is loose due to wear of the connecting pin holes. Copyright by:www.hxdlkj.com In this case, the two-way speed regulation movement that increases and decreases the fuel supply causes excessive directional lag. When the engine is working, the speed regulation reaction will inevitably lag behind the actual speed change, but the hysteresis cannot be too large, otherwise a large adjustment amplitude will be generated. The adjustment amplitude is too large, that is, when the speed has risen and fall due to the increase or decrease of the fuel supply, the fuel will continue to increase or decrease until the speed exceeds the control range of the speed controller, and the strong feedback signal will not realize the reverse adjustment reaction through the speed controller. As a result, the speed control reaction exceeds the predetermined range, causing the speed control reaction to be

    The abnormal high temperature of the generator set may be caused by the following reasons
    Although the temperature has gradually dropped, abnormal temperature of the generator set must be paid attention to. As one of the more questions consulted by customers, how do abnormal high temperature failures of the generator set occur? Let’s take a look at the reasons analysis of Haixing Power’s technicians. Only by finding the reasons can we take effective countermeasures. The reasons for the high temperature of the generator set are as follows: 1. Long-term overload operation. The diesel engine will increase its fuel consumption and increase its heat load, resulting in excessive water temperature. To this end, long-term overload operations should be avoided. 2. Insufficient coolant If the cooling liquid is missing in the diesel engine cooling system, it will affect the heat dissipation effect of the diesel engine and cause high temperature of the diesel engine. In this regard, the coolant stock in the radiator and expansion tank should be checked frequently, and when the liquid level is low, it should be replenished in time. 3. The cooling liquid circulation is not smooth and the thermostat is insufficient, which will reduce

    What are the fault problems corresponding to abnormal sound response in the piston ring of the generator set?
    Friends who often operate generator sets know that the piston ring is one of the vulnerable components of the generator set, and the sound is a sign of a problem. So today we will follow Haixing Power to learn and learn about what problems correspond to abnormal sound responses in the piston ring of the generator set. Haixing Power selected three representative sound failures: (1) The metal hitting sound of the piston ring. After the engine is working for a long time, the cylinder wall is worn, but the upper part of the cylinder wall cannot contact the piston ring almost maintains the original geometry and dimensions, which creates a step for the cylinder wall. If the old cylinder gasket is used or the new cylinder gasket is thin, the piston ring at work will collide with the cylinder wall steps, making a dull 'puff' metal impact sound. If the engine speed increases, the abnormal noise will also increase. In addition, if the piston ring is broken or the gap between the piston ring and the ring groove is too large, it will also cause a larger knocking sound.

    The temperature drops, remind everyone to pay attention to the seven taboos of using generator sets
    The temperature suddenly dropped a lot. Do you all feel uncomfortable? While we dress ourselves more to prevent cold and keep warm, we should not forget to pay attention to the influence of ambient temperature during the use of the generator set. Haixing Power reminds everyone to pay attention to the seven taboos for using generator sets. First, avoid releasing water too early or not releasing cooling water. Run at idle speed before turning off the heat, and wait until the cooling water temperature drops below 60℃ and the water is not hot, then turn off the heat and release the water. If the cooling water is released too early, the body will suddenly be attacked by cold air when the temperature is high, and it will cause sudden shrinkage and cracks. When water is released, the remaining water in the body should be discharged to prevent it from freezing and expanding, causing the body to swell. Second, avoid choosing fuel at will. The low temperature in winter makes the fluidity of diesel worse, the viscosity increases, and it is not easy to spray dissipate, resulting in poor atomization, deterioration of combustion, and deterioration of the power and economic performance of the generator set. Therefore, light diesel should be used in winter with low cooldown points and good ignition performance. Diesel is generally required

    Some things that are easily overlooked in the maintenance of diesel generator sets
    I believe that many diesel generator set users have such doubts. I have done every maintenance and maintenance. Why do equipment still have frequent failures or have a long life? According to the summary of Haixing Dynamic's communication and interaction with customers over the years, this is actually largely related to everyone's misunderstanding of maintenance and neglecting some small details. In summary, it is just doing XXX and ignoring XXX. Let’s take a look at some of the things that are easily overlooked in maintenance and maintenance: 1. Only replace the plunger and oil nozzle, and ignore the technical status of the oil outlet valve. After the oil outlet valve is worn, the remaining pressure of the high-pressure oil pipe will be too high, causing the oil injector to be cut off and the oil dripped, causing smoke from the exhaust of the diesel engine, knocking on the cylinder, and unstable operation. The method is to check the oil outlet valve and use a pressure gauge with a range of 0-600 kg/square centimeter to detect it. When the needle drops from 200 kg to 180 kg/square centimeter, the holding time should be greater than 15 seconds, otherwise it should be replaced.

    If the diesel generator set is not used for a long time, it will be 'bad'?
    Will the diesel generator set be broken if it is in a state of static for a long time? This statement has puzzled many users. Haixing Power will tell you in detail why the diesel generator sets are 'stopped and damaged'. copyright by:www.hxdlkj.com The filter capacity decreases. The filter plays a role in filtration of diesel, engine oil or water to prevent impurities from entering the body. In diesel oil and impurities are inevitable. Therefore, during the operation of the unit, the filter plays an important role. However, at the same time, these oil or impurities are deposited on the filter wall, causing the filter capacity to decrease. If too much is deposited, the oil circuit will not be smooth. In this way, the oil engine will be shocked due to the inability to supply oil (such as people lack oxygen). Therefore, during the use of a normal generator set, it is recommended: First, replace three filters every 500 hours for common units.

    The generator room is well ventilated to reduce noise
    In the construction of diesel generator sets, how to reduce noise is a concern for many users. Among the many computer room design links, Haixing Power believes that the key is to do a good job of ventilation design. If ventilation is done well, the noise will naturally be low! Since the diesel generator set requires a lot of fresh air when operating, it is necessary to design the exhaust air and exhaust duct of the computer room that can meet the requirements, and a large amount of noise also spreads from the inlet duct and exhaust duct to outside the computer room. A properly designed air inlet and exhaust duct are important links to reduce noise. Generally speaking, the air inlet and exhaust duct of diesel generator sets are both folded brick air ducts, and a specially made air inlet and exhaust silencer are equipped with sound-absorbing materials and perforated sound-absorbing plates in the inner cavity. At the same time, in order to ensure that the unit can operate at a normal and long-term rated power, the inlet and exhaust vents of the unit must reserve sufficient exhaust area according to the unit's use requirements. The unit's exhaust duct is equipped with a low-noise axial fan to ensure that the machine room has sufficient ventilation. The above

    Haixing Power analyzes the fault and handling of fuel tank of generator set
    The fuel tank is a fuel storage container for the generator set, which is made of stamping and welded steel plates. The inner surface is usually anti-rust treatment, and the interior is generally divided into more spaces with partitions. The part above the fuel tank is the fuel port, and a filter is at the bottom of the fuel port. To avoid vacuum inside the fuel tank during use, ventilation holes are generally drilled in the upper part of the fuel tank cover. There is an oil drain at the bottom of the fuel tank. According to Haixing Power's summary, fuel tanks are also vulnerable parts of generator sets. So what are the common problems and how to deal with them efficiently? Let’s take a look together. The parts of the oil tank that are prone to damage during long-term use of the oil tank are the welding points of the oil outlet pipe inside the oil tank and the welding points outside. When there is a dummy welding or sand hole in the internal welding area, the diesel engine will be unstable or shut down during operation. In addition, if there are too many impurities at the bottom of the fuel tank, the above phenomenon will also occur. The fuel tank is damaged
