A diesel generator set is a generator set with diesel as the main fuel. Its working process is mainly to spray diesel into the combustion chamber accurately and promptly, and the compressed air in the combustion chamber must reach a sufficient temperature to be fully burned. To meet the above two conditions, it is necessary to have a sufficiently high speed and a certain temperature in the cylinder when the diesel engine is started, so that the diesel generator set can work. When the diesel generator set cannot be started, we must pay attention to the observation so that we can determine what causes the diesel generator set to fail to start. Next, Haixing Power will introduce several common problems of the diesel generator set cannot start. 1. When starting, only the starter electromagnetic switch is heard, or when the starter starts, the starter drives the crankshaft to rotate slowly a few times, and then the starter sounds like the starter electromagnetic switch, but the crankshaft does not rotate. This phenomenon generally belongs to the battery 'disconnection'

The piston ring is the core component inside the diesel generator set engine. It is used together with the cylinders, pistons, cylinder walls, etc. to seal the combustion chamber gas. Because the piston ring is affected by high temperature and high pressure and reciprocating movement during long-term use, the wear will be aggravated. Therefore, the piston ring is generally made of multi-alloy cast iron that is resistant to wear, high temperature and has high mechanical strength. Although the piston ring is made of multi-alloy materials, long-term use will still cause wear of the piston ring. When the piston ring wears to a certain extent, the elastic force of the piston ring begins to gradually decrease, and the gap at the top, the gap at the side and the back gap will gradually increase, which will have a weakening effect on the sealing performance of the combustion chamber. This will cause the diesel in the combustion chamber to be unable to be completely burned, thereby increasing carbon deposits in the piston ring. So, what are the reasons that aggravate the wear of the piston ring? How can we avoid it? The sea is moving below

With the continuous recovery of the weather in 2015, some cities have entered high temperatures. Haixing Generator Group pointed out that while the temperature continues to rise, more companies are purchasing generator set water pumps. Everyone was worried that the generator set was not dissipating well, so they bought relevant equipment in advance in order to have a safe summer. Haixing Generator said that the generator set relies on a cooling pump to dissipate heat. In addition to the quality of the coolant, it must be paid attention to, and the sealing is also worth testing. Many generator sets do not do well in heat dissipation because the machine itself is poorly sealed and the liquid cannot cool down and is put into use again. In this case, you cannot just replace the cooling pump, but re-check and thoroughly seal it. In addition, generator sets must be heat dissipated for high temperatures, especially those equipment that operate for a long time. Here we recommend Haixing Cummins diesel diesel generator set for everyone, with good sealing and stable operation

Three months have passed since 2015 and the weather has become warmer. Haixing Generator Group reminds you that too high temperature will affect the operation of the generator set! Especially for machines that operate continuously, they may even explode if unattended. Cooling the generator set is the top priority in warming the weather, so how does the Haixing generator set cool down?

Economical and affordable are often the ultimate goal pursued by customers. As we all know, the economical unit in the traditional concept refers to power generation equipment with low power, low fuel, low faults, and long-term operation. It can be seen that traditional diesel generator sets can no longer meet the market. However, with the emergence of truly efficient and economical diesel generator sets, how much do you know?

Recently, some customers have become interested in the shaft voltage of diesel generator sets. In this regard, Haixing will give you a comprehensive introduction to what shaft voltage is and why the generator set produces shaft voltage, thereby deepening your understanding of the generator set. The shaft voltage refers to the voltage generated between the two bearing ends of the motor or between the motor shaft and the bearing when the generator is running. The generator shaft voltage always exists, but is generally not high. However, when the insulation pad loses its effect due to oil stains, damage or aging, the shaft voltage is sufficient to break through the oil film between the shaft and the bearing and discharge occurs. Over time, the lubricating and cooling oil will gradually deteriorate. In severe cases, the rotating shaft and bearing shells will burn out, causing shutdown. Why does the generator set generate shaft voltage? This is due to the imbalance of the stator magnetic field of the generator, and an induced potential is generated on the generator's rotation axis. The reason for magnetic field imbalance is generally because the local magnetic resistance of the stator core is large (for example

Diesel generator set technology plays an important role in the fields of public safety and energy security in China. Generator sets are also equipped in high-rise buildings, entertainment venues, highway construction, and even important communication facilities, nuclear power plants, hospitals, industrial manufacturing plants, hotels and office buildings. Among them, emergency generator sets are favored by many industry fields. What exactly is the reason that emergency generator sets attract much attention? Haixing will give you a detailed introduction here. copyright by:www.hxdlkj.com First of all, the emergency generator set has self-starting and fully automatic functions, which can run quickly after a power outage of the mains, making it safer and more reliable. Specifically, the control of the emergency generator set has a fast self-starting and automatic input device. When the main power supply fails and loses power, the emergency unit should be able to start up quickly to restore power supply. When the main power supply of an important project is powered off, it will be 3-5 seconds after

Thermal runaway in the generator set refers to the phenomenon that when the battery is charged at a constant voltage, the floating charging current and temperature of the battery undergo an accumulated mutual increase, resulting in the battery being damaged due to excessive temperature. When this phenomenon occurs, it may foreshadow problems inside the equipment. Therefore, everyone needs to understand the causes of thermal out of control in order to further troubleshoot the faulty parts. copyright by:www.hxdlkj.com 1. Oxygen complex reaction exothermic. The oxygen composite reaction of the oxygen produced by the positive electrode at the negative electrode is an exothermic reaction. If the heat emitted by the reaction cannot be released, the temperature of the battery will increase. 2. The battery structure is not conducive to heat dissipation. The structural characteristics of valve-controlled sealed lead-acid batteries are sealed, lean electrolyte, tightly assembled with ultra-fine glass fiber diaphragm, which are not conducive to heat dissipation, that is, this battery is not like a liquid-rich battery, which can pass through exhaust gas, a large amount of electrolyte and electrodes.

The main purpose of conducting electrical maintenance of diesel generator sets is to determine whether the unit is in good operating state. So what are the specific steps of electrical maintenance work? Haixing has compiled some of the following content for everyone. All screens that can be locked should be locked during operation. The key is controlled by a dedicated person. Do not leave the key in the keyhole. In an emergency, all personnel must be able to use the correct method of treating electric shock. It is best if the staff is trained and approved. Insulation tools must be used regardless of who is connecting or disconnecting any part of the circuit while operating. Before turning on or off the circuit, the circuit must be ensured to be safe. Metal objects are not allowed to be placed on the engine starting motor battery or on the wiring terminals. In addition, while complying with the standard maintenance steps, you also need to pay attention to the safety of maintenance operations. During the electrical maintenance process, you should also pay attention to prevention.

Some users reported that when the generator set start switch is pressed, the unit itself has a response, but the crankshaft cannot rotate, which causes the entire unit to fail to start. Haixing reminds everyone that it is necessary to consider whether it is caused by a crankshaft mechanical failure. There are many reasons for crankshaft failure, mainly three. You can check and find out the root cause. 1. Poor meshing between the unit and the flywheel teeth. The ring gear and the starter gear will impact when starting the engine, causing damage to the teeth or wear on one side of the teeth. If the teeth are damaged or worn seriously for more than three consecutive years, it will be difficult for the starter gear to mesh the teeth of the ring gear. 2. Stick the cylinder. When the engine temperature is too high, the engine stops and turns off, making it difficult to dissipate heat. The piston ring at high temperature is stuck to the cylinder and cannot be started after cooling. 3. Crankshaft lock. Due to a faulty lubrication system or lack of oil, the sliding bearings are caused to dry friction, resulting in the crankshaft being locked and unable to start. If you
