Due to the approaching peak power consumption, the number of companies or individuals purchasing generator sets has generally increased recently. Not all users are skilled in the use of generators.Then, walking into the whole process of generator set operation will help novices use it correctly and safely.The entire operation process of the generator set consists of five parts: preparation before starting, starting, running, shutting down, and maintenance after shutting down. Each part is indispensable.Some users do not do enough preparation work or maintenance work, which can easily cause the unit service life to be shortened or the unit to malfunction. Therefore, Jiangsu Haixing Power needs to remind users to follow the steps and do every step as required, so as to It does not affect electricity consumption and ensures safe use.1. Preparations before starting the generator set 1. Check the lubricating oil level, coolant level, and fuel quantity 2. Check the pipelines and joints of the diesel engine's oil supply, lubrication, cooling and other systems for oil and water leakage 3 2. Check the electrical circuits for leaks such as broken skins etc.

Many provinces have 'power shortage' before the arrival of summer, and many companies purchase diesel generator sets in case of 'power shortage'. Therefore, as summer is approaching, Jiangsu Haixing Power reminds customers to pay attention to when installing fuel tanks to ensure the safe operation of the unit. Different models of diesel generator sets have corresponding standard fuel tanks and oil supply systems. There are many types of fuel tank designs, and users can design them into discrete fuel tanks of various capacity according to requirements. Users can also design the fuel tank by themselves. When installing the fuel tank of the diesel generator set, users should pay attention to the following precautions: 1. The storage location of the fuel tank is safe to prevent fire. The fuel tank or oil barrel should be placed separately in a visible place, appropriately away from the diesel generator set, and smoking is strictly prohibited; 2. If the user makes the fuel tank by himself, they should pay attention to the fuel tank of the backup diesel generator set made of stainless steel or steel plate. Do not spray paint or galvanize the inside of the fuel tank, because they will react with the diesel, which may be possible.

Haixing diesel generator sets have excellent quality, excellent price and excellent service, so you can buy them with confidence! In order to make Haixing's diesel generator set products more in line with the requirements of users, in addition to referring to customers' opinions, Haixing also studied the standards and regulations issued by the state on diesel generator sets, making its own diesel generator set products more standardized and more applicable. Next, Haixing briefly introduces the appearance requirements for the selection of diesel generator sets stipulated by the state from the perspective of customers: ① The limit size, installation size and connection size of the unit should comply with the product drawings approved by the prescribed procedures. ② The welding of the unit should be firm, the welds should be uniform, and there should be no defects such as welding penetration, undercuts, slag inclusions and pores. The welding slag and welding medicine should be cleaned; the paint film should be uniform, without obvious cracks and fall off; the plating layer should be smooth, without leakage plating spots, rust, etc.; the unit fasteners should not be loose. ③Electrical installation requirements of the unit

　　Recently, many major cities across the country have experienced serious power shortage problems. Judging from the previous early warning of the National Development and Reform Commission and the current power limit phenomenon gradually spread across the country, this year's 'power shortage' will be very serious. At present, power shortage and the subsequent power limit have spread all over the country. All companies have purchased generator sets to generate electricity by themselves to solve the problem of power shortage. Many companies rarely use generator equipment before, and may not understand some basic operating specifications of generators. We sorted out the basic operating specifications of the generator set during use. I hope that when using generator sets, we will strictly follow the operating specifications to ensure electricity use! For a generator powered by a diesel engine, the operation of its engine part is carried out in accordance with the relevant regulations of the internal combustion engine. Before starting the generator, you must carefully check whether the wiring of each part is correct, whether the connecting part is firm, whether the brushes are normal, whether the pressure meets the requirements, and whether the grounding wire is good. Before starting

[Overview] The insulating system of the generator set is a measure to ensure user safety. Risk factors such as leakage and insulator damage are partly affected by the customer's wrong operations or the external environment. Local discharges in the insulator of the generator set, which are unknown to everyone, will also be caused. Jiangsu Haixing Power Systematically explains the mystery to everyone. 1. What is local discharge of generator sets? What are the main forms? Under the action of an electric field, the electric field strength of the local area of ​​the insulator in the insulator system reaches the breakdown field strength, and discharge occurs in some areas. This phenomenon is called Partial Discharge. Partial discharge occurs only in the insulation part and does not penetrate the entire insulation. The local discharge in the generator set mainly includes internal discharge of the main insulation of the winding, end corona discharge and tank discharge (including tank corona). In addition, there is also a hazardous discharge in the generator set, which is caused by the breaking of the stator coil strand or joint.

The three most common problems in excitation generator sets: demagnetization, loss of step, and oscillation. Although Jiangsu Haixing Dynamics explained these issues separately before, many customers still have questions, so we will summarize this solution. 'Demagnetization' 'Phenomenon' During the operation of the generator set, after the generator is demagnetized due to the open circuit, short circuit, small excitation current or rotor circuit failure, the relevant meter of the generator and the excitation system are as follows: 1. The rotor ammeter and voltmeter indicate zero or close to zero; 2. The stator voltmeter indicates significantly lower; 3. The electronic ammeter indicates higher and shake; 4. The generator's active power meter indicates lower and swing; 5. The generator's active power meter indicates negative value. The generator loses the excitation current during operation, causing the magnetic field of the rotor to disappear. This may be caused by accidental tripping of the excitation switch, failure of the excitation machine or semiconductor excitation system, and disconnection of the rotor circuit. When the demagnetization hair

In recent years, large-scale data centers have grown rapidly and will be applied to more and more high-power UPS. Due to the need to control the amount of batteries used in UPS, the delay time of high-power UPS is basically 15-30 minutes, which requires matching power generation. The unit provides continuous power supply to the equipment.Based on the above reasons, we have to face the problem of matching and compatibility between high-power UPS and generator sets. The following are some personal suggestions for reference for people in the power industry:

1. Basis for purchasing diesel generator sets 1) The performance and quality of the selected diesel generator set must comply with relevant standards. Diesel generators are widely used in telecommunications, financial departments, hospitals, schools, commerce and other departments, industrial and mining enterprises and residential buildings. Emergency backup power supply, independent power supply for special purposes such as military and field operations, vehicles and ships.(Copyright © WWW.HXDLKJ.COM) As a diesel generator set for communication, it must meet the requirements of G3 or G4 in GB2820-1997, and at the same time, it must meet the requirements of the 'Implementation Rules for Network Quality Certification and Testing of Diesel Generators for Communication' 24 performance index requirements must also pass the strict inspection of the Communication Power Equipment Quality Supervision and Inspection Center established by my country’s industry authorities.As a diesel generator set for military communications, it must meet the relevant requirements of GB2820-1997 and GJB.

Definition: Biomass energy is solar energy fixed on the earth through photosynthesis of plants. It has the potential to become one of the major new energy sources in the 21st century.

When it comes to the frequency of generator sets, many uninformed customers will think that the higher the frequency, the better. However, after long-term use, the generator set is damaged. Jiangsu Haixing Power summarized this technical article for your reference for this type of customer, so that customers can promptly discover unit problems during use and reduce maintenance costs. Generally, the frequency of the generator set should not exceed 52.5HZ, i.e. 5% of the rated value. Therefore, if an abnormality in the frequency of the generator set is found during use, timely measures should be taken. When the frequency increases, it is mainly limited by the rotational mechanical strength. The high frequency and the motor speed are high. When the speed is high, the centrifugal force on the rotor increases, which easily causes damage to some parts of the rotor. When the frequency decreases, the following problems will occur: (1) The frequency decrease causes the rotor speed to decrease, which reduces the air inlet of the fans at both ends, which deteriorates the generator's cooling conditions and increases the temperature of each part. (2) Low frequency
