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 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

Many users like to check, disassemble and repair by themselves when there is a problem with their equipment. In this case, Haixing would like to remind everyone that such operations require staff to understand the structure of the generator set. Have you done this? copyright by:www.hxdlkj.com Some maintenance personnel are not very clear about the mechanical structure and principles of the equipment, do not carefully analyze the cause of the fault, and do not accurately determine the fault location, so they disassemble and repair the equipment. As a result, not only the original fault cannot be eliminated, , and new problems may arise. Therefore, when a mechanical failure occurs, you must first select someone who is familiar with the structure of the power generation equipment to inspect it, and use testing equipment to conduct the inspection; if there is no testing equipment, you can use the traditional fault diagnosis method of 'ask, look, check, and try' and methods, etc., combined with the structure and working principle of the equipment, determine the possible fault location. Follow from simple to

The oil in the generator set mainly plays a lubricating role, and lubrication work is an important means to extend the life of the unit and improve efficiency. Therefore, it is crucial to choose lubricating oil with reliable quality. So, in real life, is there any way to identify the quality of engine oil and guard against inferior engine oil? Haixing believes that everyone can take the following measures. First put the engine oil in a test tube and heat it to 110 to 120 degrees Celsius. If there is a 'crackling' sound in the oil, it means there is water in the engine oil. If there is water in the oil, use indirect heating to heat the oil to 110 to 120 degrees Celsius. When the bubbles in the oil disappear, cool to normal temperature and the water will be removed. If you unfortunately suffer a loss and buy low-quality lubricating oil and there is no way to complain, we can use the above method to evaporate the water and continue to use it. If the engine oil has been slightly emulsified, use the following methods to deal with it: collect emulsified engine oil of the same brand and add

The exhaust pipe design of the generator set is in place and reasonable, which can not only ensure the normal operation of the unit, but also create a good machine room environment for users. Therefore, it is very particular when designing and installing smoke exhaust pipes. Haixing Power has compiled the following suggestions for users: 1. All smoke exhaust pipes should be well supported and fixed. Unsupported silencers cannot be installed on the unit manifold or unit boost outlet. 2. A soft connection should be installed between the smoke pipe and the unit to absorb the thermal expansion and contraction of the pipe, the displacement and vibration of the unit; the soft connection should be as close as possible to the smoke outlet of the unit (supercharger or exhaust manifold). 3. Rainproof caps, covers and other rainproof designs should be installed at the end of the exhaust pipe to prevent rain and snow from entering. The part of the smoke pipe close to the unit should be installed with a condensate collector and drain valve. 4. It is recommended that the unit equipment share the exhaust pipe. Carbon dust and condensate emitted by equipment during operation

Generator sets are now used more and more widely in many fields, and users have higher and higher requirements for generator sets, especially schools, hospitals, government units, etc., which have put forward high requirements for the bass performance of generator sets, emphasizing that The unit is designed with low noise in mind. So, how to ensure that the generator set meets the requirements when purchasing? This requires customers to learn to detect decibels. Today Haixing will introduce it to you. copyright by: www.hxdlkj.com 1. Do not exceed the 1M testing distance when testing the generator set. 2. Choose an open, open site without buildings. No debris or barriers will increase the noise of the generator set. 3. Choose to test the decibels of the diesel generator set in the dead of night to avoid inaccurate data caused by the increase in other noises. 4. It must be placed outside the generator set.

We all know that when operating a generator set, the operator must develop good operating habits and consciously abide by the operating specifications, so as to effectively extend the service life of the generator set and improve work efficiency. However, in the actual operation process, many operators still have bad habits. Therefore, Haixing has summarized six 'don'ts' for everyone to compare. copyright by: www.hxdlkj.com (1) Do not run the diesel engine under load without warming up after starting the cold engine. When the diesel engine is cold started, due to the high viscosity and poor fluidity of the oil, the oil pump will not supply enough oil, and the friction surface of the machine will be short of oil. Poor lubrication will cause rapid wear and even malfunctions such as cylinder pulling and tile burning. Therefore, after the diesel engine is cooled and started, it should be run at idle speed to warm up, and then run under load when the standby oil temperature reaches above 40°C; the machine should be started in low gear and drive in each gear sequentially for a mile.

The power of the generator set is not only related to its own operating conditions, but also closely related to the working environment. Only a suitable working environment can make the generator set reach the rated power. Otherwise, the power of the generator set will be reduced. Today Haixing will introduce to you the relationship between the power of the generator set and the working environment. copyright by: www.hxdlkj.com (1) When using a generator set, the altitude should not exceed 1000m. If it exceeds 1000m, the power will be reduced, and the higher the altitude, the more the power will drop. (2) The working environment temperature of the generator set is preferably between 5-40°C. Automated units without oil and water preheating devices require an ambient temperature of 25-40°C; exceeding this range will reduce the power of the unit and cause low temperatures. Difficulty in starting may also occur. (3) The relative humidity of the air when using the generator set is not greater than 90

Heavy humidity in the air or staff mistakes may cause the generator set to get damp. A damp generator set will cause its insulation resistance performance to decrease, posing certain safety hazards. How to dry the generator set must be faced. Correct question, Haixing will introduce to you the specific method of drying the generator set: Directly short-circuit the three-phase outlet terminals of the stator winding of the generator set and make a reliable connection. Adjust the maximum resistance position of the voltage regulating transformer in the excitation circuit. If the resistance is not large enough, connect another resistor to increase the resistance. Then start the generator set, pay attention to slowly accelerating to the rated speed, and then slowly adjust excitation current. The excitation current is determined based on the dampness of the generator set. However, the stator winding short-circuit current must not exceed the rated current. In addition, the ventilation conditions of the generator storage environment must be improved and good ventilation equipment must be provided. If in cold season
