Diesel generator set is an efficient power supply equipment composed of four parts: diesel engine, cooling water tank, generator, chassis, control box and fuel tank. Diesel generator sets are widely used in mining, railways, field construction sites, road traffic maintenance, electric power, factories, post offices, communities, buildings, schools, enterprises, hospitals and other departments because of their small size, flexibility, lightness, complete supporting facilities, and easy operation and maintenance. , as a backup power supply. As a long-established power generation equipment manufacturer, Haixing Power has accumulated rich experience in operating diesel generator sets, which we will share with you below. 1. Diesel engine running-in: New or overhauled diesel engines must be run-in for 60 hours before being put into full-load use. To improve the working condition of the moving parts of the diesel engine and improve the reliability and service life of the diesel engine. Running-in should consider the specific running-in plan depending on the purpose of the diesel engine and the towing method.

Diesel generator sets that need to operate for a fixed period of time for a long time are called common diesel generator sets. There are three major difficulties in the purchase of this type of equipment, which is to determine the capacity, number and speed of the units. As a professional power generation equipment manufacturer, Haixing Power gives the following suggestions. 1. Determination of the capacity of commonly used diesel generator sets Copyright by: www.hxdlkj.com The output power of the unit in long-term continuous operation can meet the calculated load selection of the entire project, and the backup unit capacity of the generator set should be determined according to the importance of the load. The continuous output power of a diesel engine is generally 0.9 times the calibrated power. 2. Determination of the number of commonly used diesel generator sets. The number of commonly used diesel generator sets is usually set to more than 2 to ensure the continuity of power supply and adapt to changes in the power load curve. Only when the number of units is large can the power consumption be

When purchasing diesel generator sets, many users are obsessed with power. Some unscrupulous merchants on the market will take advantage of people's lack of understanding of power to set up purchasing traps, causing people to make wrong judgments when purchasing. Haixing Power, a professional manufacturer of diesel generator sets, will provide you with a detailed analysis of the knowledge related to the power of diesel generator sets. Engine power calibration is based on mechanical strength, thermal load strength, and fatigue life. The same generator set can be calibrated to different powers according to the load rate and the length of use. GB2820-2009 is equivalent to standard ISO8528 and is divided into four types of power according to usage requirements: 1. ESP, emergency backup power 2. LTP, limited time operating power 3. PRP, basic power 4. COP, continuous power emergency backup power (ESP) Emergency Standby power is fixed

In fact, the so-called parallel operation of diesel generators means that two or more generators with the same rated voltage and the same phase are merged into the same bus to supply active power and reactive power to the system. This is the parallel operation of the generators. Then we start one generator set first, and then send the generated voltage to the bus. After the other generator set is started, it will be paralleled with the previous generator set at this time. At the moment of closing, The generator set will not experience abnormal inrush current, and the rotating shaft will not be subject to sudden impact. However, we should consider the overall current loop problem during parallel operation, so how should we protect the loop? Next, Haixing Power will give you a brief analysis. 1. The phenomenon of reverse power and reverse power is caused by the difference in rotation speed (frequency) and voltage of the generator sets. That is, one generator set has positive power, while the other generator set has negative power.

As we all know, long-term use of diesel generator sets will cause some parts to wear out, and then they are not inspected and maintained during normal use. As the diesel generator sets accumulate over time, one day suddenly the diesel generator set cannot start and generate electricity. The electromagnetic switch coil of the machine is burned out. Next, Haixing Power will introduce to you the reasons why the electromagnetic switch coil burns out? The diesel generator set cannot start, and then the electromagnetic switch burns out, which often occurs in the holding coil. The reasons are as follows: 1. The holding coil of the diesel generator set is relatively thin, and current flows through the diesel generator set during the entire starting process, and the working time is long. ; The wire diameter of the suction coil is relatively thick and the working time is short. It only passes current for a moment before the end of the main circuit is turned on. 2. When the diesel generator set is in poor technical condition, the starting time is too long, causing the holding coil to overheat and burn out.

my country has used biogas to generate electricity for more than 30 years, but the domestic biogas power generation research and application market are still in an imperfect stage. Biogas power generation has received widespread attention and active promotion in some developed countries. The use of biomass energy to generate electricity and connect it to the grid accounts for about 10% of total energy in Western Europe.

A diesel generator set is a generator set that uses diesel as the main fuel. Its working process is mainly to inject diesel into the combustion chamber accurately and timely, and the compressed air in the combustion chamber must reach a sufficient temperature for complete combustion. To meet the above two conditions, the diesel engine must have a high enough speed and a certain temperature in the cylinder when starting, so that the diesel generator set can work. When the diesel generator set cannot start, we must pay attention to observation in order to determine what is causing the diesel generator set to fail to start. Below, Haixing Power will introduce to you several common diesel generator sets that cannot start. problem. 1. When starting, you only hear the 'clucking' sound of the starter electromagnetic switch, or when starting for the first time, the starter drives the crankshaft to rotate slowly for a few times, and then there is a 'clucking' sound of the starter electromagnetic switch, but the crankshaft does not rotate. This phenomenon generally belongs to the 'broken grid' of the battery.

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?
