The manufacturer believes that this problem may be caused by damage to the fuse or rectifier diode. When the fuse is blown, the power indicator light of the charger does not light up; when the rectifier diode is damaged, the power indicator light of the charger is on, but there is no DC output. 1. The charger transformer is burned out. 2. The diode on the charger is burned out. 3. The charging ammeter of the charger is damaged. 4. The charger's fuse is burned out. The method to troubleshoot the fault is: disconnect the connection line between the charger and the battery, use a multimeter DC voltage barrier (50V) to test the voltage between the two output terminals of the charger. Note that the red meter pen is connected to the positive electrode of the charger, and the black meter pen is connected to the negative electrode, and there is no voltage output. Remove the charger housing and inspect the charging insurance core. It was found that the 60A safety core was burned out. After replacement, the charger resumes normal charging and the fault is eliminated.

The diesel generator set is mostly caused by the long-term static unit. The various materials of the unit itself will undergo complex chemical and physical changes with engine oil, cooling water, diesel, air, etc., which are mainly manifested in two aspects. It is summarized as follows: The filter filter capacity decreases. The filter plays a role in filtration of diesel, engine oil or water to prevent impurities from entering the body. In diesel oil and impurities are also inevitable. Therefore, during the operation of the unit, the filter plays an important role, but at the same time, these oil or impurities are deposited on the filter wall, causing the filter filter capacity to decrease. If too much is deposited, the oil circuit will not be smooth. In this way, the oil engine will be shocked due to the inability to supply oil (such as human beings lack of oxygen). Therefore, during the use of a normal generator set, the editor of the diesel generator set public platform recommends: 1. Commonly used units are 500. Replace three filters every two years; 2. Replace three filters every two years for the backup unit. Cooling system

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. Today, 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 the international 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 1. Emergency backup power (ESP) Emergency backup power is defined as: under agreed operating conditions and according to the manufacturer's specified maintenance interval and

The function of the fuel supply system of the diesel generator set is to store and filter diesel, and inject diesel into the combustion chamber in a specified working order, in a regular, quantitative, and pressure-based manner with the corresponding fuel injection quality according to the different working conditions of the diesel engine, so that it can be mixed and burned quickly and well with the air, and finally discharged the exhaust gas into the atmosphere. copyright by:www.hxdlkj.com What route does fuel flow through to achieve oil supply and combustion? Let’s explore the specific process with the pair of Haixing Dynamics. The oil transfer pump sucks the diesel from the fuel tank, filters out impurities through the filter, and enters the low-pressure oil chamber of the fuel injection pump. The fuel injection pump increases the fuel pressure and injects it into the combustion chamber through the high-pressure oil pipe to the fuel injection tube. A very small amount of fuel leaked in the gap between the needle valve and pairs of the injector inside the injector and excessive fuel in the low-pressure oil chamber of the injector pump flow back to the fuel tank through the return pipe. Then, let's take a look at the combustion system weight

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. The capacity of commonly used diesel generator sets is determined by the long-term continuous operation of the unit. The output power can meet the maximum calculated 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 by having a large number of units can the number of units put into the generator set according to the change of power load, so as to make the diesel

For a long time, there have been great obstacles to the development of diesel generator sets in my country. On the one hand, there are trade barriers and technical constraints overseas, and on the other hand, we also have shortcomings in after-sales and certification. Here, Haixing Power will analyze the main bottlenecks in the development of diesel generator sets from five aspects.

Recently, Haixing Power organized employees to strengthen their professional knowledge learning, actively and proactively devote themselves to the work of diesel generator sets, and always maintain full enthusiasm. At present, Haixing Power is in the stage of transformation and upgrading. In order to accelerate the realization of the goals, the company encourages employees to study in-depth on the content of Zichai New Energy's training and learning in Zibo last year, as well as the basic knowledge of the biogas control project involved in our company. In order to increase everyone's enthusiasm, the company will also conduct weekly examinations on learning content, and the examination results will be included in the performance salary assessment and evaluation. In order to solve the problems encountered by everyone during the learning process in a timely manner, the company will arrange a dedicated person to collect and feedback the problems encountered during the learning process in a timely manner and solve them. In addition to existing information, Haixing also encourages employees to find more rich information through the Internet to carry out their study and work hard to improve their professional qualities. At the same time, through learning, the

Customers’ requirements for the function, performance, price, quality, etc. of generator set products are basic requirements. As the competition in the generator set market becomes increasingly fierce, customers have begun to pursue higher-level requirements - service requirements. Only when the customer service provided by generator set companies meets the new market needs can they be recognized by more customers. Therefore, Haixing Power believes that generator set companies should further improve their customer service system, and the specific implementation methods are as follows. copyright by:www.hxdlkj.com 1. Ensure the smooth flow of information channels. From the problem returned by customers to the customer service staff receiving processing, to the relevant staff solving the problem, and finally the customer service staff will feedback the problem handling results to the customer. The main line of information transmission in the entire customer service system ensures its smoothness.

Next, Haixing will explain the specific content: 1. Working grounding (1) Reduce the electric shock voltage. For systems where neutral point is not grounded, when one phase is grounded and the human body touches one of the other two phases, the electric shock voltage is more than 1.7 times the phase voltage; for systems where neutral point grounding, the electric shock voltage drops to close to or equal to the phase voltage. (2) Quickly cut off the faulty equipment. For systems with neutral points that are not grounded, when one phase is grounded, the current path can be formed due to the presence of capacitance and insulation resistance of the wire and the ground. The grounding current is very small, which is not enough to cause the protection device to operate and cut off the power supply, and cannot ensure personal safety. For neutral point grounding systems, when the first phase is grounded

After the diesel enters the filter, it passes through the filter paper and collects it in the filter cartridge drum, and then goes to the oil injection pump through the oil outlet. The impurities and moisture accumulated at the bottom of the shell are released from the oil drain screw plug at the bottom of the shell. From this flow perspective, everyone should know that the filter has a great impact on the combustion quality, and combustion determines the final power generation effect, which means that the role of the filter cannot be ignored. Then, during the contact between Haixing Power service personnel and customers, we found that many users easily ignore the maintenance of equipment filters in the generator set maintenance work. Let’s take a look at the specific content, learn these precautions, and let the generator set show a combustion effect and provide excellent power supply in the following operations. 1. Some users lose the upper and lower sealed rubber gaskets and oil cover of the filter element when maintaining the diesel filter, so that the diesel does not filter through the filter element, and the gap between the filter element and the filter cover is unimpeded.
