Diesel Generator Tech

The diesel generator set must be regularly maintained by professionals, so as to ensure the stability of the unit in use. However, in the maintenance of diesel generator sets, the safety of operators is the key content of the work. Today, Dingbo Power Generation Equipment will share the knowledge of unit maintenance safety with you, hoping to give you some help. The  diesel generator set maintenance  safety knowledge is shared as follows: (1) Strictly implement the safety operation regulations of diesel generator set formulated by the manufacturer. When inspecting or repairing the electrical equipment of the unit, operations should not be carried out before cutting off the power supply. (2) Operators should wear rubber shoes with good insulation performance. Do not wear bare feet or cloth shoes. The body should not be soaked through. Do not operate the diesel generator set or play with the wires with wet hands. (3) The diesel generator set shall be equipped with a grounding device to e

Alternators and regulators have been widely used in automobiles due to their simple structure, reliable operation, and convenient maintenance. When the following situations occur to the AC generator and regulator, in general, the following methods can be used for emergency maintenance of the   AC generator   and regulator. (1) When the electronic regulator or contact regulator does not match the grounding method of the AC generator and is urgently needed, the grounding method of the AC generator field winding can be changed to make the grounding method of the AC generator and regulator consistent. (2) When checking whether the AC generator generates electricity, if there is no test light or multimeter at the moment, a fuse or other fine wire from the car can be used to ground and scrape the AC generator B+terminal. If there is a spark, it can be basically confirmed that the AC generator generates electricity; If there is no response, it indicates that the AC generator is not generating

Cavitation failure of diesel generator set mainly refers to the diesel engine caused by cavitation damage. In fact, cavitation failure of diesel generator set has become an important factor affecting the service life and reliability of modern units. So how can our users avoid such malfunctions in their daily use? How did such a malfunction occur? The   diesel generator set manufacturer   will talk about relevant topics with you, hoping to help you. 1. Usage factors (1) The coolant temperature that is most prone to pitting corrosion is 40 ℃ -60 ℃, so it is important to maintain the coolant at a normal working temperature (80 ℃ -85 ℃) during use. (2) The cooling liquid specified by the diesel generator set manufacturer shall be added instead of hard water or cooling water (liquid) with more impurities. Experiments have shown that hard water containing salts and alkalis has a pitting rate several tens of times higher than clean soft water.  (3) Try to reduce the time for idle, heavy load,

The front oil seal of the crankshaft of the Cummins diesel generator set has oil leakage fault, so why does the oil seal oil leakage fault occur when the   Cummins diesel generator set   has not been running for a long time? In this article, Dingbo Power Generation Equipment will provide users with a brief analysis, and the specific content is as follows: The front oil seal of the crankshaft of the Cummins diesel generator set leaks oil, which is an oil seal fault. It is impossible to prevent oil leakage. Although the oil leakage rate is not high among the multiple oil seals of the Cummins diesel generator set engine, it is also very cheap, but there are many replacement and disassembly parts, and the labor cost is high, which is a typical minor ailment. So, the reasons for its failure have been analyzed by engineers, but there are only three points. (1) The aging oil seal of Cummins diesel generator set engine can only be a rubber product in Cummins diesel generator set engine accesso

The diesel generator set is a mechanical equipment that converts other forms of energy into electrical energy. It is driven by a water turbine, steam turbine, diesel engine or other power machinery, and converts the energy generated by water flow, air flow, fuel combustion or atomic Nuclear fission into mechanical energy and transmits it to the diesel generator set, which then converts it into electrical energy.   Diesel generator sets   are widely used in industrial and agricultural production, national defense, science and technology and daily life. How to maintain the radiator of the diesel generator set? The maintenance cycle of the radiator of the diesel generator set is once every 200 hours of operation. External cleaning: Spray with hot water (including detergent). The method is to spray from the front of the radiator to the fan (if sprayed from the opposite direction, the dirt will only approach the center). When using this method, cover the diesel generator set with adhesive t

Sometimes we need to be careful when adding water to the water tank of the diesel generator set. We need to pay attention not only to the purchase, but also to the details when using the diesel generator set, so as to avoid improper use affecting the life of the diesel generator set. Next, we will begin to understand the requirements of adding water to the water tank of the   diesel generator set . 1. Do not add well water or sewage. Water can be divided into two types based on whether it dissolves minerals: hard water and soft water. Hard water contains iron, calcium, and magnesium plasma. Untreated well water and spring water belong to hard water. If such hard water is added to the engine, it will produce compounds such as calcium carbonate and calcium sulfate after being heated and evaporated by the engine, which will precipitate and form scale. And scale, on the one hand, is a poor conductor of heat, and on the other hand, when scale increases to a certain extent, it will narrow th

We can only carry out maintenance operations on the generator after it stops operating. Before maintenance, it is not only necessary to disconnect the starting circuit of the prime mover and the connection of the battery, but also the closed circuit between the power grid and other generators to ensure the normal and safe operation of the diesel generator set. 1. Quarterly inspection: During the quarterly inspection, the  generator set  needs to be at a load of over 70% to operate for one hour to burn out the mixture of diesel and oil in the cylinder. 2. Daily inspection: During the daily inspection, it is necessary to check the external parts of the generator set and the battery for any leakage or liquid leakage. Check and record the voltage value of the battery and the temperature of the cylinder liner water. In addition, it is necessary to check whether the heater for the cylinder liner water, the charger for the battery, and the dehumidifier heater are operating normally. 3. The ge

When fuel economy, high thermal efficiency, and operating conditions change, the fuel consumption rate curve of Volvo generator sets changes relatively flat, and Volvo generator sets are also economical at low loads, with lower harmful emissions. The Volvo generator set has a wide range of applications, reliable and durable operation, and low faults due to the lack of ignition system. The maintenance operation of   Volvo generator sets   is simple, with fewer people, and maintenance is easy during standby period. The comprehensive cost of construction and power generation for Volvo generator sets is the lowest, with fast start-up and the ability to quickly reach full power in just a few seconds. The emergency shutdown process with full load within 1 minute is short, and frequent start and stop can be achieved. For turbocharged diesel Volvo generator sets, due to the low load, no load, and low boost pressure of the Volvo generator set, it is easy to cause a decrease in the sealing effec

Diesel generator set is a diesel engine that extinguishes diesel oil to obtain energy release. The advantages of diesel generator set are high power and good economic performance. The operation of the Diesel generator is similar to that of the diesel generator set. Each operation cycle goes through four strokes: intake, compression, and exhaust. However, since the fuel used for diesel generator set  diesel engine  is diesel, its viscosity is larger than that of joint venture Cummins, and it is not easy to evaporate, and its Autoignition temperature is lower than that of Cummins, so the formation and incineration method of combustible mixture are not the same as those of Sino US joint venture Cummins. The main difference is that the mixture in the cylinder of a diesel engine is compression ignition, rather than ignition. When the diesel generator set is running, the atmosphere enters the cylinder. When the air in the cylinder is compressed to the end point, the temperature can reach 500

In the AC circuit of a silent generator set, a pure resistance circuit where the current and voltage in the load are in phase and can cancel each other out. The method of paralleling capacitors on the inductive load of a silent generator set can compensate for the reactive power of the inductive load by the reactive power of the capacitors, thereby reducing or even eliminating the original energy exchange between the inductive load of the silent generator set and the power source. Most of the loads in the power system are inductive, so the total current will lag the voltage by an angle, and the   silent generator se t's parallel capacitors will be connected in parallel with the load. The current of the capacitor will offset a portion of the inductance current, thereby reducing the total current and increasing the power factor. Insufficient cooling water in a silent generator set can reduce its cooling effect. Silent generator sets overheat due to ineffective cooling, and high oil t

Each generator brand has its own oil mist protection system. Its main protection element is the oil mist detector, which can timely detect whether the generator has oil mist formed in the generator crankcase due to excessive air leakage and other faults caused by bearing overheating or piston ring damage, so as to monitor whether the main operating components of the generator, crankshaft and cylinder, work normally. During the operation of the   generator , it continuously extracts the oil and gas in the crankcase through the sampling pipeline system and sends them to a sensitive and accurate concentration measuring device. The photoelectric diode senses the light intensity generated by infrared radiation and converts the generator's light intensity signal into an electrical signal to be sent to the electronic identification device. If the gas in the generator crankcase contains oil mist, the opacity of the measurement channel of the concentration measurement device will increase.

Today we are talking about the battery of high-power giesel generator. Do users who often use high-power diesel generator to generate electricity have the habit of maintaining the battery? So how should I maintain it? When it comes to batteries, the first thing you think of is the batteries of electric vehicles. With the powerful technology, electric cars are also very popular. It should be noted that batteries and batteries are not the same thing. Devices that can store and discharge repeatedly can be called batteries, such as Lead–acid battery, lithium batteries, and so on. Maintenance skills of high-power  diesel generator  battery: Firstly, wipe. Firstly, we need to use a slightly damp cloth to scrub the exterior of the battery (long-term use can cause dust and oil stains to adhere), and clean the battery panel, pile head, and other debris that may cause leakage. Frequently scrubbing the battery in this way will prevent the pile head of the battery from accumulating white acid corr

After starting the Volvo generator set, the speed should be slowly increased. After checking and confirming that everything is in good condition, no-load operation from low speed to rated speed can be carried out. When the Volvo generator set is running at no load, it is important to check the oil pressure of the Volvo generator set and identify the situation before starting. If everything is normal, it can be put into normal operation. The operator should closely monitor the changes in the instruments on the control screen to see if they are within the permitted range and make corresponding adjustments. During operation, operators should maintain a safe distance from live equipment and wear labor protective equipment. The switching operation should pay attention to the sequence. When the Volvo generator unit stops normally, it should first unload some of the load, then turn off the main switch, and finally turn off the diesel engine of the  Volvo generator set . It is not allowed to n

If the generator set does not start according to the starting requirements, it may accelerate the depreciation of the generator set and easily cause unnecessary losses and waste. In order to ensure the normal operation of the generator set, Starlight   power generation   equipment reminds users to follow the rules when starting the genset, and to avoid the following bad starting methods. 1. Starting during a long period of time with a motor, the battery will be discharged during a long period of time with high current, which can easily cause bending of the electrode plate. Moderate discharge can easily cause vulcanization of the electrode plate, resulting in the battery being scrapped. 2. Dry start: After the generator set is started, it can participate in cooling water, which can easily cause the body parts to heat up too quickly and accelerate wear. Adding cold water to a hot car can also cause the body to explode. 3. Enhanced electric power starting: By connecting two batteries in p
