    How to effectively save oil for generator sets?
    Fuel is indispensable to generator sets. During operation, we must observe the amount of fuel in time. As a considerable operating cost expenditure, how can we save oil? Haixing’s staff summarized six points: 1) Maintain the optimal oil supply angle: The oil supply angle is offset, which will cause the oil supply time to be too late and the fuel consumption will increase significantly. copyright by: www.hxdlkj.com 2) Ensure that the machine does not leak oil: The treatment method is to apply valve paint to the gasket and grind it on the glass plate to smooth it, and the oil pipe joint is positive. A diesel recovery device is added, and the return oil pipe on the oil nozzle can be connected to the hollow core screws to allow the return oil to flow into the oil tank. 3) Increase the temperature of the cooling water of the diesel engine: Increased water temperature can make the diesel burn more completely, the oil viscosity will be smaller, which can reduce motion resistance and achieve fuel-saving effect. 4) Appropriately increase the pulley of the diesel engine to lower the diesel engine

    How to confirm the source of generator set noise
    The abnormal noise of the generator set may be a sign of problems within the equipment. How do we determine the source of the noise and then confirm the faulty components? Haixing has compiled several common component noise characteristics and simple reasons for easy review. copyright by: www.hxdlkj.com 1. Exhaust noise: Exhaust is a high-temperature and high-speed pulsating airflow noise. The main components of exhaust noise are as follows: low-frequency pulsating noise caused by periodic smoke exhaust, air column resonance noise in the smoke exhaust pipe, Helmholtz resonance noise in the cylinder, and noise caused by high-speed airflow passing through the valve gap and bent pipes. 2. Mechanical noise: Mechanical noise is usually caused by the sensation or impact of each other caused by the periodic changes of gas pressure and motion inertia forces during operation. 3. Burn

    How to deal with the generator set after water is injected?
    If your generator set equipment is not processed in time after large-scale water inlet, it will cause great damage to the equipment and accelerate the occurrence of rust and corrosion. Therefore, Haixing recommends that you understand the relevant conventional maintenance methods. 1. Rinse the surface of the diesel engine with water to remove soil and debris, and then use metal cleaning agent or washing powder to remove oil stains on the surface. 2. Push one end of the diesel engine so that the oil drain part of the oil pan is at the lowest position. Rotate the oil drain screw plug and pull out the oil ruler so that the water in the oil pan flows out by itself. When it is about to release the oil, slightly let the oil and water be released together and then rotate the oil drain screw plug. 3. Remove the air filter, remove the upper case of the filter, remove the filter element and other components, remove the water in the filter, and clean each part with metal cleaning agent or diesel. If the filter is plastic foam, wash it with washing powder or soapy water (gasoline is not allowed), then rinse it with clean water and dry it.

    What causes oil leakage in the generator set?
    Oil leakage occurs from generator sets from time to time. Haixing briefly analyzed the parts that are prone to oil leakage and the causes, hoping to help everyone solve the problem. 1. The quality of the purchased or homemade paper pads does not meet the requirements, such as insufficient thickness, improper storage, wrinkles and deformation, or inadequate cleaning, and dust and impurities during assembly, all of which are the causes of oil leakage. copyright by: www.hxdlkj.com 2. The oil pressure is too high, which also causes oil leakage on the static joint surface. 3. The quality of the static joint surface itself is mainly determined by the accuracy of the processing equipment itself and storage and transportation conditions. If the equipment is high in accuracy, the flatness and roughness of the static joint surface can meet the design requirements of the drawing, and pay attention to preventing bumps during storage and transportation, so it is not difficult to achieve complete sealing of the static joint surface. However, because the equipment accuracy and process level of some manufacturers are still low, the storage and transportation conditions and management levels cannot be completed.

    Clogged filter will cause oil pressure to drop
    There are many reasons for the low oil pressure of the generator set. What Haixing wants to explain in detail today is one of the factors that cause this phenomenon, the filter is blocked. copyright by: www.hxdlkj.com When the oil filter is blocked and the oil cannot pass smoothly, the safety valve installed on the filter base will be pushed open, so that the oil directly enters the main oil channel without passing through the filtration. However, if the opening pressure of the safety valve is too high and cannot be opened in time, it will increase the leakage of the oil pump and reduce the oil supply to the main oil duct, and the oil pressure will also decrease. The oil filter should be maintained on time and the safety valve opening pressure should be adjusted correctly to 0.35-0.45MPa. In addition, if the safety valve spring ages and the valve seat and the steel ball are not tightly closed, the oil will leak a lot, causing the oil to foam in the oil pan. At this time, you can see the oil covered with foam when you pull out the dipstick. In addition, the oil pump is oiled

    Common electrical control problems in generator sets
    The electrical control problem of generator sets is a small fault that everyone often encounters during operation. Haixing gives you a few real cases below to facilitate everyone to understand the cause and solution. 1. When the key is turned to 'START', the diesel generator set does not start 1. Check whether the key switch is operating well 2. Check whether there are any defect indications, fix the problem and reset 3. Check the battery voltage. If the voltage is too low, the battery needs to be recharged to full. If the voltage is normal, check whether the voltage signal can be correctly sent to the control link, such as the throttle solenoid valve and the start motor, etc. 4. Check whether the emergency stop button can be relaxed 2. When the 'START' signal is correctly input, but cannot be started manually/automatically 1. Check whether the emergency stop button can be relaxed 2. Check whether the control key is in the 'STOP' position 3. Check whether there are any defect indications, fix the problem and reset 4. Check the battery voltage, if the voltage is too low

    How to prevent cavitation in generator sets?
    The cavitation of the generator set refers to the surface of the outer wall of the wet cylinder liner of the diesel generator set in contact with the coolant, which is damaged into some needle-shaped holes. These holes gradually expand and deepen, and finally form deep holes or cracks. In what ways can the problem of cavernous erosion be prevented? Haixing Power summarized it from three aspects. (1) Usage factor a. The temperature of the coolant that is most prone to cavitation is 40℃-60℃. Therefore, during use, try to keep the coolant at a normal working temperature (80℃-85℃). b. Use the coolant specified by the manufacturer, without hard water or cooling water (liquid) containing more impurities. Experiments show that hard water containing salts and alkalis has a cavitation rate of dozens of times higher than clean soft water. c. Minimize the time of idle speed, heavy load and overload operation. d. Use fuel according to regulations to alleviate the rough work of the diesel generator caused by combustion. (2) Maintenance factors a. Replace according to regulations

    How to judge the fault based on the exhaust gas discharged from Cummins diesel generator
    After the fuel of Cummins diesel generator is completely burned, the normal exhaust color is generally light gray, and when the load is slightly heavy, it is dark gray. During the operation of Cummins diesel generators, abnormal phenomena such as black smoke, white smoke, and blue smoke occasionally occur. It is a condition for judging the failure of Cummins diesel generators. Haixing Power analyzes it as follows: (1) Black smoke diesel is a complex hydrocarbon compound. Unburned diesel sprayed into the combustion chamber is decomposed at high temperature to form carbon black. When exhaust gas is exhausted, black smoke is formed. Black smoke is a manifestation of incomplete combustion of fuel in the combustion chamber. The main influencing factors are as follows: 1. After the piston ring, cylinder liner, etc. wear, the piston ring and cylinder liner are worn, the compression pressure is insufficient, causing the normal proportion of the mixture to change at the end of the compression stroke, causing the fuel to burn under an oxygen-free conditions and produce carbon deposits. 2. The fuel injector does not work well and the fuel injector does not atomize or drip oil, so that the fuel does not

    Pay attention to the use of generator sets in harsh environments
    With the improvement of the technical level of the generator set industry, the scope and fields of products are also expanding and extending. In recent years, under the environment of large-scale expansion of national infrastructure, generator sets have become more and more frequently used in some fields. In order to ensure the service life of the equipment, here is Haixing, here to share the attention paid to the use of generator sets in harsh environments. 1. Engines with generator sets are used in high-altitude plateau areas, especially natural intake engines. When used in plateau areas, due to the thin air, it cannot burn so much fuel like at sea level, and some power is lost. For natural intake engines, the power loss is about 3% for every 300m increase at an altitude. Therefore, when the plateau is indeed working, a lower power should be used to prevent smoke and excessive fuel consumption. 2. Work in extreme cold climates 1) Add to use auxiliary
