It has advantages such as energy conservation, emission reduction, improving energy supply safety, and promoting the development of the circular economy. It is an irreversible trend in the development of the modern energy field. The 8th Coal Equipment and Mining Technology Equipment Exhibition 2012 was held in Beijing from June 28 to 30. Many coal and related industries and enterprises

Many customers believe that diesel generator sets do not need to be owned by themselves. When you need to use it, you only need to rent it and return it after it is used up. This way, maintenance is not considered, saving a lot of money. In fact, it is best to own a diesel generator set yourself, and renting it is not necessarily more cost-effective than buying it. Let me introduce you in detail why you buy a diesel generator set better than renting it? First of all, there is no doubt that the rented diesel generator sets have been used by many manufacturers, and many of them are products that are on the verge of elimination. Compared with the purchased generator sets, the average fuel consumption is much higher. And the longer the manufacturer uses it, the greater the economic losses. In the end, the manufacturer will find that the cost of renting and purchasing a new machine is actually similar. Secondly, the charge for renting a diesel generator set is calculated based on the power generation time. The longer you rent, the higher the rental fee will be. If power generation is stopped during the lease

A diesel generator is a small power generation equipment, which refers to a power machine that uses diesel as fuel and uses diesel as prime mover to drive the generator to generate electricity. The entire set of units is generally composed of diesel engines, generators, control boxes, fuel tanks, starting and controlling battery, protection devices, emergency cabinets and other components. Generators have a wide range of uses in industrial and agricultural production, national defense, science and technology and daily life. Nowadays, many bad vendors and purchasing agents have falsely reported the brand and power of their products in order to make huge profits, which has caused customers to have great misunderstandings about the brand and performance of diesel generator sets. So how to correctly purchase generator sets is what we care about. Next, I will tell you the traps encountered in the purchase process. 1. Confusing the relationship between KVA and KW, treating KVA as KW exaggerates power and selling it to customers. In fact, KVA is apparent power, KW is effective power, 2. Don’t talk about the relationship between long-line (rated) power and backup power

The temperature in winter is low, and the cylinder head of the diesel generator is very easy to explode. Therefore, the following methods hope to help everyone 1. Add cold water after starting. After the diesel engine is started, the temperature in the diesel generator will rise. If cold water is added, the cylinder block and cylinder head will cool down sharply, and it will crack due to cold shrinkage. 2. After the machine is shut down, no cooling water is released. The machine says it is frozen into ice, the volume increases, and the cylinder block and cylinder head swell and crack. 3. When the engine is operating, the cooling water is short or the temperature of the water tank boiler is too high. Suddenly participate in the cooling water. The cylinder block and cylinder head are too cool and shortened. 4. The generator set is operated for a long time and the temperature inside the machine is high. After parking, the high-temperature water will be released immediately, which will cause the high-temperature parts to suddenly encounter cold air and crack. 5. Use decompression to stop the machine, so that the high-temperature cylinder head will suddenly encounter cold air and cause cracking. There are the following methods to avoid cracking of various cylinder blocks and cylinder heads. 1. Before starting the diesel engine, the water supply tank should be participated.

When there is oil leakage, water leakage or air leakage in diesel generator sets: 1. Add a pad to treat leakage. Oil leakage is leaked at the diesel engine oil pipe joint, and a layer of double-sided smooth thin plastic pad can be added to both sides of the leak-proof gasket. Tighten it hard to prevent leakage. 2. Paint sheet liquid leakage treatment method: leakage at joints such as diesel engine oil tank, water tank, crankcase, etc. You can soak the paint sheet in alcohol and apply the paint sheet liquid to clean the joints to cure leakage. However, the paint sheet is expensive and is usually only used in urgent situations. 3. When the paper pads in the oil pan, cylinder head, gear chamber cover, crankcase back cover of the diesel engine leak, as long as the paper pad is intact and the joint surface is clean, you can apply a layer of butter on both sides of the paper pad and tighten the bolts to prevent leakage. If you change to a new paper pad, soak the new paper pad in diesel for 10 minutes before installation, then remove it and wipe it clean, apply a layer of butter on the joint surface before installing it. 4. Liquid sealing glue leak treatment method diesel engine

1. Fault phenomenon: The starter motor transmission gear cannot enter the meshing cause: 1. The starter motor relay does not work ① The starter button is damaged or has poor contact. ② The contacts of the switch burn out. ③Insufficient voltage (battery is out of power, poor contact or leakage of circuit system). Solution: ① Repair or replace the start button. ② Remove and clean the contacts. ③Check electrical circuits and batteries. 2. The starter motor transmission gear cannot mesh with the diesel engine flywheel ring. ①The gear has heavy wear or bleed on one side. ② The starting motor gear is not parallel to the center line of the flywheel ring. ③The gap between the end face of the motor gear to the end face of the flywheel ring is too large or the top is dead. ④ Start the lever decoupling of the motor. Solution: ① Maintain gears. ② Reinstall, non-parallel phenomenon. ③The gap should be within the range of (2.5~5) mm, and if the required spacer is not included,

After summarizing years of unit experience, the generator manufacturer also summarized some reliable methods for estimating the price of second-hand diesel generator sets. Below, diesel generator manufacturers will share this method with you. The method can be carried out by asking one question, looking two, and trying three tests. Question 1: I ask about the purchase time, purpose and reason for the diesel generator set, the repair situation and what major parts have been replaced, and what problems are there in use, etc., so as to have a relatively comprehensive understanding of the machine. Second look: First, check whether the model is an out-of-date model, then look at the new and old degree of the diesel generator set from the appearance, and finally check whether the parts are complete and whether there are any damage. The third test: The test machine is the specific steps: 1. Shake the flywheel up and down, if there is no sound or obvious shaking, it means that the gap between the main journal of the crankshaft and the bearing shell is not large; if there is no clicking sound, it means that the wear between the journal of the crankshaft connecting rod and the bearing shell is not serious. 2

When the battery of a diesel generator set is not in use for a long time, appropriate charging must be given before use to ensure the normal capacity of the battery. (The actual capacity of the battery can be detected by a hydrometer) Normal operation and charging will cause some water in the battery to evaporate, which requires frequent rehydration of the battery. Before rehydration, first clean the dirt around the filling port to prevent it from falling into the battery grid. Then open the filling port and add an appropriate amount of distilled water or pure water. Do not add it too much (using the scale of the battery plate as the standard). Otherwise, when the battery is discharged/charged, the electrolyte inside the diesel engine will gush out from the overflow hole of the filling port, causing corrosion and damage to surrounding objects and the environment. Avoid starting the battery at low temperatures. The battery capacity will not be output normally under low temperature environments, and long-term discharge may cause battery failure (cracking or explosion). The battery of the backup generator set should be maintained and charged regularly and can be equipped with a floating charger. diesel fuel

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
