In order to extend the service life of the diesel generator set and its efficiency, in addition to seasonal maintenance, the daily maintenance of the diesel generator set cannot be ignored. Only by starting from the details can the diesel generator set be made good use of it. Let’s follow Haixing Power to take a look at the daily maintenance and emergency start-up procedures of diesel generator sets. copyright by:www.hxdlkj.com 1. Daily inspection and maintenance of emergency generator sets 1. An emergency generator no-load start test is carried out on Monday of the third week of each month. 2. Check and record the generator room and body every week. 3. The unit starts and runs for no less than 20 minutes each time to ensure lubrication of the unit's moving parts. 4. Check the tightening of the box wire, neutral wire and ground wire of the generator set 5. General inspection content 1) Check the oil volume of the fuel tank. 2) Check the oil level of the diesel engine. 3

Generator sets generally use synchronous generators (also known as electric balls) to convert the rotating mechanical energy of diesel engines into electrical energy. Various electrical equipment must rely on the power it emits to work, so the working performance requirements of synchronous generators are very high. The working principle of synchronous generators copyright by:www.hxdlkj.com Synchronous generators are manufactured based on the principle of electromagnetic induction. Modern alternators usually consist of two parts of coils; in order to improve the strength of the magnetic field, part of the coil is wound in the groove of the inner wall of a cylinder stacked with a metal sheet with good magnetic conductivity. This cylinder is fixed to the base and is called a stator. The coils in the stator can output induced electromotive force and induced current, so it is also called an armature. Another part of the coil of the generator is wound in the groove of a cylinder stacked with a strong magnetic permeability metal sheet in the stator cylinder, called a rotor. A shaft passes through

Every day, many users come to consult some diesel generator set failure problems. In order to let everyone know the causes and treatment methods of common faults, Haixing Power staff organized and shared them with everyone, hoping that they will be useful to everyone. Common fault introduction: 1. Why do the exhaust pipe sometimes drip oil when the generator load is too low? Since there are many places in the engine that use pressure seals, such as between the cylinder liner-piston-piston ring, and between the supercharger-supercharger rotor shaft, this seal usually only fully plays a role when the engine has about 1/3 of the load, and slight leakage may occur when the load is small. Therefore, foreign engine manufacturers generally emphasize in their manuals. If the unit is running under small load, as the running time continues, the following faults will occur: ①. The piston-cylinder liner is not sealed well, the oil will rise and enter the combustion chamber to burn.

Engine cylinder pulling refers to obvious longitudinal mechanical scratches and scratches in the inner wall of the cylinder within the range of motion of the piston ring. In severe cases, melting wear occurs, causing the engine to start up or the engine to shut down on its own. Pulling the cylinder is a major accident in the engine. According to the experience summary of Haixing Power technicians, the fundamental reason for the cylinder pulling of the generator set is that it is difficult to form an oil film between the inner wall of the cylinder and the piston ring and the piston, which causes poor lubrication and even dry friction. There are many specific reasons for this situation. There are roughly three aspects to summarize: The reasons for the piston group 1. The gap between the piston ring is too small. If the opening gap, edge gap or back gap of the piston ring is too small, the piston ring is heat expansion and stuck when the engine is working, pressing tightly with the cylinder wall, or the piston ring is broken, it is easy to pull out the groove on the cylinder wall. 2. The piston pin burst out.

The diesel generator set is an efficient power supply equipment composed of four major parts: diesel engine, cooling water tank, generator, chassis, control box, and fuel tank. Diesel generator sets are widely used in mines, railways, field construction sites, road traffic maintenance, power, factories, post offices, communities, buildings, schools, enterprises, hospitals and other departments as backup power sources. As an old power generation equipment manufacturer, Haixing Power has accumulated rich experience in diesel generator set operation, so I will share it with you below. 1. The diesel engine run-in new or overhauled diesel engine must be run-in for 60 hours before it is officially used before it can be put into full load. To improve the working condition of the diesel engine moving parts, improve the reliability and service life of the diesel generator set of the diesel engine. The run-in plan should be considered depending on the use of the diesel engine and the drag method.

Diesel generator sets that need to operate for a long time during a fixed period are called commonly used diesel generator sets. There are three major difficulties in purchasing such equipment, namely, determining the capacity, number of units and speed of the unit. As a professional power generation equipment manufacturer, Haixing Power provides the following suggestions. 1. Determination of capacity of commonly used diesel generator sets copyright by: www.hxdlkj.com The output power according to the long-term continuous operation of the unit can meet the load selection of the entire project, and the capacity of the generator set backup unit should be determined based on the importance of the load. The continuous output power of the diesel engine is generally 0.9 times the calibration power. 2. Determine the number of commonly used diesel generator sets. The setting for determining the number of commonly used diesel generator sets is usually more than 2 units to ensure the continuity of power supply and adapt to changes in the applied electrical load curve. Only when the unit is large can it be used according to the power consumption

In the purchase of diesel generator sets, many users are confused about power. Some bad merchants on the market will also use their lack of understanding of power to set purchase traps, which leads to people making wrong judgments when purchasing. Haixing Power, a professional diesel generator set manufacturer, will analyze the relevant knowledge of diesel generator set power for you in detail. The basis for engine power calibration is 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 time. GB2820-2009 is equivalent to standard ISO8528, and is divided into four powers according to the usage requirements: 1. ESP, emergency backup power 2, LTP, limited-time operation power 3, PRP, basic power 4, COP, continuous power emergency backup power (ESP) Emergency backup power fixed

In fact, the so-called parallel operation of diesel generator sets means that two or more generators have equal rated voltages and the same phases, and are incorporated into the same busbar at the same time to supply active and reactive power to the system. This is the parallel operation of the generator. Then we are running a generator set first and then sending the generated voltage to the busbar. After the other generator set is started, it is parallel to the previous generator set. At the moment of closing, the generator set will not experience abnormal impact current, and the shaft will not be hit suddenly. However, when we carry out parallel processing, we should consider the overall current loop problem. So how should we protect the loop? Let’s briefly analyze it for you below. 1. The reverse work phenomenon is caused by different speed (frequency) and voltage of the generator set, that is, one generator set has positive work, while the other unit has negative work.

As we all know, diesel generator sets will cause wear and tear in certain parts during long-term use, and then they will not be inspected and maintained during normal use. With such accumulation of time, the diesel generator set suddenly one day, and the generator electromagnetic switch coil burned out. Next, Haixing Power will introduce to you what are the reasons for the burnout of the electromagnetic switch coil? This causes the diesel generator set to fail to start, and then the electromagnetic switch is burned, 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 passes through the entire starting process of the diesel generator set, which is long working time; the diameter of the pull-up coil is thicker and the working time is short, and the current passes through the moment before it is turned on at the end of the main circuit. 2. When the diesel generator set is in poor technical condition, the starting time is too long, which causes the retaining coil to overheat and burn.

my country has a history of using biogas to generate electricity for more than 30 years, but the domestic biogas power generation research and application market is 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 power grids accounts for about 10% of the total energy in Western Europe.
