The weather is getting colder and winter is approaching. Many users and friends are starting to have headaches again. Starting difficulties are not a big problem, but they will also cause some trouble to the operation of the equipment. Therefore, we must learn to change the starting conditions of the generator set. There are three main contents to refer to: copyright by: www.hxdlkj.com 1. The decompression method uses the method of reducing the pressure of the intake or exhaust valve of the diesel engine to reduce the compression ratio, thereby reducing the starting resistance, and starting the diesel engine. This method is used more frequently in winter. For some small diesel engines, manufacturers generally design special pressure reducing devices to reduce the resistance during starting. 2. Preheating method. The methods for preheating diesel engines generally include air preheating, engine oil preheating and cooling water preheating. No matter which method is used for preheating, it must be determined based on specific conditions. 3. Use large snails

During the operation of the generator set, the operator will check the equipment status regularly and keep relevant records. Among them, the problem of water pump bearing leakage is one of the common faults. Let’s learn how to troubleshoot this fault with Haixing Power. This kind of fault is generally caused by damage to the water seal. Troubleshooting water leakage in the water pump bearing: 1. Check the overflow hole on the fresh water pump housing and find that the overflow hole is blocked by a wooden rod. After clamping it out with pliers, the cooling water leaks out from the overflow hole, and the bearing overflow disappears. When the overflow hole is blocked by the wooden rod, the pressure is generated due to the rotation of the water pump impeller, which eventually causes the cooling water to be sprayed out from the water pump bearing gap. After removing the wooden rod, the cooling water left in the water seal leaks directly from the overflow hole in the pump housing. 2. After shutting down the machine, the water seal was dismantled and inspected. It was found that the water seal was damaged. After replacement, the water leakage of the fresh water pump disappeared. Stop is involved in troubleshooting

In summer, Haixing constantly reminds everyone about the issues of heat dissipation and cooling water. In fact, cooling water has a lot to do with the season. Let’s follow the staff to see how cooling water changes with the season. copyright by:www.hxdlkj.com The temperature in winter is low, the ambient temperature of the generator set is also low, and the temperature of the coolant will also be very low, so the temperature of the coolant will rise a little slower. For example, when the Cummins generator set exerts the maximum effective power, the temperature of the coolant should be around 80°. Therefore, when using generator sets in winter, the water temperature is around 80°. The temperature is high in summer, and some areas may even experience high temperatures above 40°. The coolant of the generator set rises very quickly in such high temperature seasons. The generator set is prone to cause cylinder pulling accidents at 100° water temperature, so the generator set has coolant exceeding 95°

Sometimes many netizens will anthropomorphize generator sets, and people rely on fresh air to survive. So does generator set also put forward requirements for air? This kind of doubt will arise. Haixing Dynamic believes that it may be related to severe smog weather, and everyone will feel that smog affects the operation of the equipment. In fact, this understanding is not without reason. The amount of impurities contained in the air can not only harm people's health, but also cause failure and damage to diesel generator sets. The quality and circulation of air play a decisive role in the diesel generator set, and we must pay attention to it during use. If the generator set is used indoors, we must ensure that there is enough fresh air. If the machine room is sealed too tightly, it will lead to poor air circulation. This will not only affect the diesel combustion rate of the diesel engine, but also reduce the cooling effect of the unit. If the air inlet cooling is not achieved, the heat generated by the unit cannot be discharged, and the temperature in the machine room will gradually

When the generator set is running short of cylinders, abnormal noise, insufficient power, jitter and other symptoms may occur. During the generator set operation, one or two cylinders do not work, and other cylinders act normally. What is the reason for this? The following is a summary of the problem by Haixing Power Copyright by:www.hxdlkj.com① When starting in cold winter, due to the cold weather, some cylinders do not work because of the idle speed when starting for the first time every day, but with the increase of the operating temperature, all cylinders gradually work normally; ② Due to the excessive load, some cylinders have mechanical failures such as piston ring breakage, cylinder pulling or valve sealing, which makes the cylinder compressive pressure less than required, resulting in the cylinder not working; ③ Due to the quality of the oil used by the user, the fuel injector nozzle is blocked or stuck, so the cylinder does not inject oil, so the cylinder does not work; ④ The fuel injector pump plunger and oil outlet valve fail, resulting in the cylinder supply.

The unstable voltage of the generator set may also be a common problem, and many operators have encountered such a situation. Haixing briefly summarizes six reasons and requires everyone to pay attention to it. 1: The unstable speed of the diesel engine causes the voltage of the generator set to be unstable. 2: The damage to the generator set voltmeter causes the false image of voltage instability. Of course, most generator sets now use smart displays, so this phenomenon no longer exists. 3: If the load borne by the generator set is too large, the voltage will be unstable. 4: Damage to the voltage regulator components of the generator set causes unstable voltage of the generator set. 5: The poor circulation of the fuel pipe of the generator set causes unstable engine speed and causing unstable voltage. This can be attributed to point 1. 6: Unstable load of the equipment used can also cause unstable voltage of the generator set. Generator unit operation

Can the generator set be placed after shutdown or shutdown according to normal procedures? It is obviously inappropriate to do so. After the generator set relationship, some subsequent operations are required to end the entire shutdown process. What are the subsequent operations? Haixing Power summarized it for everyone: Check whether there are 'three leakages' phenomena in the unit (lubricating oil, fuel, coolant);

The basic reasons for the power drop in diesel generator sets Haixing briefly discussed with you before. Generally speaking, the power of the equipment will drop after use for a period of time, but there are no adverse conditions or symptoms, which is classified as a normal phenomenon. What Haixing Power should emphasize is that in addition to factors such as natural wear, air humidity, and temperature that affect power, some components of the generator set will also bring power changes to the diesel generator set. The main reasons are: 1. The air filter is too dirty and the air inhalation is not enough. At this time, the air filter must be cleaned or replaced; 2. The fuel filter device is too dirty and the fuel injection volume is not enough, so it must be replaced or cleaned; 3. The ignition time is incorrect and must be adjusted. High air temperature and high humidity will reduce the power of the diesel engine, and component problems will also reduce the power. To prevent such problems, the key is to rely on card maintenance. Timely maintenance and maintenance can not only improve the reliability of the equipment work, but also have

Netizens have a thorough understanding of the daily operation rules, precautions, fault inspections and other knowledge of generator sets by checking the information on Haixing Power’s official website. In recent discussions, everyone turned their attention to some preparations before the operation. Haixing staff think it is necessary to take a look at nine routine inspections before starting. Routine inspections before the diesel generator set operation: 1. Appearance inspection: copyright by: www.hxdlkj.com Whether the external engine of the generator set is damaged and complete, whether the screws are tightened, and whether the generator output line and control line are damaged and loose. 2. Fuel system: 1. Whether the diesel amount is sufficient, whether there is any oil leakage or loose pipe fittings, etc., and remove the remaining air in the fuel system. 2. Lubrication system: Is the engine lubricant sufficient? New engine

Vibration failures of generator sets are very common, and Haixing Power also has a lot of contact. According to daily experience summary, the causes of vibration mostly come from the fault problems of internal components, and everyone needs to check them one by one from the following aspects. 1. The axis system of the linkage part is not centered, the center line does not overlap, and the centering is incorrect. The main reason for this failure is that it is caused by poor alignment and improper installation during the installation process. There is another situation where some linkage center lines overlap and coincide in the cold state, but after running for a period of time, the center lines are destroyed due to deformation of the rotor fulcrum, foundation, etc., which causes vibration. 2. There are problems with the gears and couplings connected to the diesel generator set. This type of fault is mainly manifested in poor gear choking, serious wear of the gear teeth, poor lubrication of the gear, skewed and misaligned coupling, wrong tooth shape, tooth pitch, tooth gap, or serious wear, which will cause certain vibrations.
