The piston ring is the core component inside the diesel generator engine. It completes the sealing of the combustion chamber gas together with the cylinder, piston, cylinder wall, etc. Because piston rings are affected by high temperature, high pressure and reciprocating motion during long-term use, wear will increase. Therefore, piston rings are generally made of multi-alloy cast iron that is wear-resistant, high-temperature resistant and has high mechanical strength. Although the piston ring is made of multi-element alloy material, long-term use will still cause wear of the piston ring. When the wear of the piston ring reaches a certain level, the elasticity of the piston ring begins to slowly decrease, and the gap at the top, side and The side gaps and backlash will also 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 incompletely burned, resulting in an increase in carbon deposits in the piston rings. So, what are the reasons that will increase the wear of piston rings? How can we avoid it? The sea below is stirring

As the weather continues to warm up in 2015, some cities have already entered hot weather. Haixing Generator pointed out that as the temperature continues to rise, more companies are buying water pumps for generator sets. Everyone is worried about the poor heat dissipation of the generator set, so they purchase relevant equipment in advance in order to have a stable summer. Haixing Generator Set said that the generator set relies on a cooling pump to dissipate heat. In addition to the quality of the coolant that must be paid attention to, the sealing is also worth testing. The heat dissipation work of many generator sets is not done well, because the sealing of the machine itself is poor, and the liquid cannot be cooled before being put back into use. In this case, you cannot just replace the cooling pump, but recheck and thoroughly seal it. In addition, generator sets must do a good job of heat dissipation in hot weather, especially those equipment that have been running for a long time. Here we recommend Haixing Cummins diesel generator sets to everyone. They have good sealing and stable operation.

Three months have passed since 2015, and the weather has become warmer. Haixing Generator reminds you that excessive temperature will affect the operation of the generator! Especially machines that run continuously may even explode if left unattended. Cooling down the generator set is the first priority in warmer weather, so how does the Haixing generator set cool down?

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 generates shaft voltage, so as to deepen everyone's understanding of the generator set. Shaft voltage refers to the voltage generated between the two bearing ends of the motor or between the motor shaft and the bearings when the generator is running. The generator shaft voltage always exists, but it is generally not high. However, when the insulating pad is oily, damaged or aged, etc. When it loses its function, the shaft voltage is enough to break down the oil film between the shaft and the bearing and discharge occurs. Over time, the quality of the lubricating and cooling oil will gradually deteriorate. In severe cases, the rotating shaft and bearing bushes will be burned out, causing shutdown accidents. Why does the generator set generate shaft voltage? This is due to the unbalanced magnetic field of the stator of the generator, which generates an induced electromotive force on the rotating shaft of the generator. The reason for the unbalanced magnetic field is generally due to the large local magnetic resistance of the stator core (for example

Diesel generator technology plays an important role in the fields of public safety and energy security in China. Generators 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 which emergency generator sets are favored by many industries. What is the reason why emergency generator sets attract so 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, so that it can run quickly after a power outage, making it safer and more reliable. Specifically, the control of the emergency generator set has fast self-starting and automatic input devices. When the main power supply fails and the power is cut off, the emergency unit should be able to quickly self-start to restore power supply. When the main power supply of an important project is cut off, it will take 3-5 seconds to confirm the

Thermal runaway of the generator set refers to the cumulative mutual growth between the battery's float current and temperature during constant voltage charging, resulting in battery damage due to excessive temperature. When this phenomenon occurs, it may indicate a problem within the equipment. Therefore, everyone needs to understand the cause of thermal runaway in order to further troubleshoot the faulty component. copyright by:www.hxdlkj.com 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 through exhaust gas and a large amount of electrolyte like a flooded battery. Heji

The main purpose of performing electrical maintenance on a diesel generator set is to determine whether the unit is in good operating condition. So what are the specific steps for electrical maintenance? Haixing has compiled the following content for you. All screens that can be locked should be locked during operation, and the key should be held 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. Personnel engaged in this work should preferably be trained and recognized. Whoever is working on connecting or disconnecting any part of an electrical circuit must use insulated tools. Before connecting or disconnecting a circuit, the safety of the circuit must be ensured. Do not allow metal objects to rest on the starter motor battery or remain on the terminals. In addition, while complying with standard maintenance procedures, everyone also needs to pay attention to the safety of maintenance operations. Everyone should also pay attention to precautions during electrical maintenance.

Some users have reported that when the generator set start switch is pressed, the unit itself responds but the crankshaft cannot rotate, causing the entire unit to fail to start. Haixing reminds everyone that at this time, you need to consider whether it is caused by a mechanical failure of the crankshaft. There are many reasons for crankshaft failure, and there are three main reasons. You can compare them to find out the root cause. 1. There is poor meshing between the unit and the flywheel teeth. The ring gear and starter gear will collide when starting the engine, causing tooth damage or single-sided wear of the teeth. If more than three teeth in a row are damaged or severely worn, it will be difficult for the starter gear and ring gear teeth to mesh. 2. Sticky cylinder. When the engine temperature is too high, the engine stalls and the heat is difficult to dissipate. The piston rings at high temperatures adhere to the cylinder and cannot be started after cooling. 3. The crankshaft is locked. Due to a failure in the lubrication system or a lack of engine oil, the sliding bearing causes dry friction, which eventually locks the crankshaft and prevents it from starting. If you

The weather is getting colder and winter is approaching. Many users are beginning to have headaches due to difficulty in starting. Difficulty in starting is not a big problem, but it will also bring some trouble to the operation of the equipment, so we must learn to change the generator set. For the starting conditions, there are mainly three aspects for reference: copyright by: www.hxdlkj.com 1. Pressure reduction method, which uses the method of decompressing the intake valve or exhaust valve of the diesel engine to reduce the compression ratio, thereby reducing the starting resistance. , start the diesel engine. This method is used more in winter. For some small diesel engines, manufacturers generally design special pressure reducing devices to reduce resistance during starting. 2. Preheating method. Methods for preheating diesel engines generally include air preheating, oil preheating and cooling water preheating. No matter which method is used for preheating, it must be determined according to specific conditions. 3. Use large snails
