    Analysis of several causes of generator set running without cylinder
    When the generator set is running without a cylinder, abnormal noise, insufficient power, and jitter may occur. When the generator set is running, one or two cylinders do not work, but other cylinders function normally. What is the reason for this situation? ? The following is Haixing Power’s summary of the issuecopyright by: www.hxdlkj.com ① During cold starts in winter, due to the cold weather, some cylinders do not work at idle speed when starting for the first time every day. However, as the operating temperature increases, all cylinders gradually work normally; ② Due to excessive load, individual cylinders The piston ring in the cylinder is broken and the cylinder is pulled. Or a mechanical failure such as a loose valve seal causes the cylinder compression pressure to fall below the required level, causing the cylinder to not work; ③ Due to quality problems with the oil used by the user, the injector nozzle parts are clogged or stuck, causing the cylinder to not work. Fuel injection occurs, so the cylinder does not work; ④The fuel injection pump plunger and oil delivery valve malfunction, causing the cylinder to supply

    The reasons for unstable voltage of the generator set may be:
    The unstable voltage of the generator set may also be a common problem, and many operators have encountered such a situation. Haixing simply summarizes the reasons for this in six aspects that everyone needs to pay attention to. 1: The unstable speed of the diesel engine causes the voltage of the generator set to be unstable. 2: Damage to the voltmeter of the generator set causes the illusion of voltage instability. Of course, most generator sets now use smart displays, so this phenomenon no longer exists. 3: The generator set is prone to voltage instability if the load is too large. 4: Damage to the voltage regulator components of the generator set causes instability in the voltage of the generator set. 5: Poor circulation in the fuel pipe of the generator set causes unstable engine speed and unstable voltage. This can be attributed to point 1. 6: The unstable load of the equipment used will also cause the voltage of the generator set to be unstable. Generator set operation

    What are the subsequent operations after the generator set is shut down?
    Can the generator set be left alone after shutting down or stopping according to normal procedures? This is obviously inappropriate. After the generator set is connected, some follow-up operations are required to complete the entire shutdown process. What does the follow-up operation include? Haixing Power has summarized for everyone: Check whether the unit has 'three leaks' (lubricating oil, fuel, coolant);

    Parts will affect the power of the generator set
    The basic reasons for the power drop of diesel generator sets have been briefly discussed by Haixing before. Generally speaking, the power of the equipment will drop after being used for a period of time, but there will be no adverse conditions or symptoms. This is classified as a normal phenomenon. Haixing Power would like to emphasize that in addition to natural wear, air humidity, temperature and other factors affecting power, some parts of the generator set will also bring changes in power to the diesel generator set. The main reasons are: 1. The air filter is too large. If it is dirty, the air intake is not enough, the air filter must be cleaned or replaced. 2. The fuel filter device is too dirty, and the fuel injection amount is not enough, it must be replaced or cleaned. 3. The ignition time is incorrect and needs to 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 upkeep can not only improve the reliability of the equipment, but also There can still be

    Nine routine checks need to be done before starting the generator set
    Netizens have a thorough understanding of the daily operation details, precautions, fault inspections and other aspects of the generator set by consulting the information on the official website of Haixing Power. In recent discussions, everyone has once again turned their attention to some preparations before operation. Haixing The staff believes that it is still necessary for everyone to come together and take a look at the nine routine inspections that need to be done before starting. Routine inspections before operation of the diesel generator set: 1. Appearance inspection: copyright by: www.hxdlkj.com Whether the outside of the 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 or loose. 2. Fuel system: 1. Whether the amount of diesel is sufficient, whether there is any oil leakage or loose fittings in the wiring and piping, and remove the remaining air in the fuel system. 2. Lubrication system: Is the engine lubricating oil enough? new engine

    Which component problems will cause the generator set to vibrate?
    Vibration faults in generator sets are very common, and Haixing Power has been exposed to them more often. According to daily experience, the causes of vibrations mostly come from the failure of internal components. We need to investigate one by one from the following aspects. 1. The shaft system of the linkage part is misaligned, the center lines do not coincide, and the centering is incorrect. The main cause of this failure is poor alignment and improper installation during the installation process. Another situation is that the center lines of some linkage parts are coincident in the cold state, but after running for a period of time due to the deformation of the rotor fulcrum, foundation, etc., the center lines are destroyed again, resulting in vibration. 2. The gears and couplings connected to the diesel generator set are faulty. This kind of failure mainly manifests as poor gear meshing, severe gear tooth wear, poor lubrication of the opposite wheel, skewed and misaligned couplings, incorrect tooth shape and pitch of the gear coupling, excessive clearance or severe wear, all of which will cause certain problems. vibration.

    Measures to deal with the water outage of the generator set
    Frequent high-temperature weather in summer requires everyone to pay attention to the abnormal temperature of the generator set and also to prevent water outages. If you encounter a water outage during operation, how to take effective measures? Haixing Power will introduce to you: During operation, when the generator set's water cutoff signal is sent, the operator should immediately check the time and be prepared to deal with the accident if the water cutoff protection refuses to operate; at the same time, find out the cause and restore the water supply as soon as possible. If the cooling water is restored within 20S, a comprehensive inspection of the cooling system and various parameters should be carried out, especially the water supply of the stator coil. If the water flow is found to be blocked, the inlet water pressure should be immediately increased to restore the water supply or the train should be immediately decoupled and shut down; if the water cutoff time reaches If the water cutoff protection refuses to operate after 20 seconds, the generator circuit breaker and magnetic switch should be opened manually immediately.

    There are many factors to consider when purchasing a generator set
    After selling generator sets for so many years, the customer service staff of Haixing Power concluded that the purchase of generator sets is still a question that is repeatedly mentioned by everyone. How to choose correctly? Haixing Dynamics believes that multiple factors must be considered comprehensively. copyright by: www.hxdlkj.com When purchasing a diesel generator set, you should fully consider the comprehensive performance and economic indicators of the diesel generator set, the supplier's professionalism, geographical location and actual professionalism, and whether the supplier has after-sales service means, such as Emergency repair vehicles, special machinery, etc. Then consider whether the selected unit power matches the electrical load power. Generally, it is better to select the unit power based on: unit rated power x0.8 = power of electrical equipment. If there are large and medium-sized motors, 2-5 times the starting current needs to be considered. If the unit is mainly used to charge the UPS, professional consultation must be done based on the actual situation of the UPS before charging.

    The increase in fuel consumption of generator sets should be addressed from three aspects:
    The increase in fuel consumption of generator sets means an increase in usage costs, which users are not willing to see. To deal with the problem of increased fuel consumption, Haixing Power recommends that you start from three aspects. The following three common reasons cause the fuel consumption of the generator set to increase: 1. The fuel injection pump plunger is adjusted so that the fuel supply volume is too large, or the adjusting ring gear locking screw is loose, causing the adjustment ring gear to shift, resulting in the fuel injection pump fuel supply volume being reduced. Too big. 2. The adjustment screw in the speed regulator that limits the maximum oil volume of the rack is adjusted too large or the throttle handle limit screw is adjusted too large. 3. Too much engine oil in the speed regulator will increase the oil supply and lead to 'speeding'. When the fuel supply is too high, fuel consumption will increase, fuel combustion will be incomplete, severe carbon deposits will occur in the combustion chamber, accelerated wear of the cylinder, piston and piston rings, and even overheating and cylinder knocking will occur. Therefore, it is necessary to deal with it in time to avoid abnormal smoke. Is a symptom of burning problems
