In the process of contacting customers, Haixing’s staff found that many customers are very vague about how to accurately order generator sets. Today, Haixing will teach you what to pay special attention to when ordering generator sets: Generally, the ordering of generator sets should be marked with the following Content: (1) Unit model, rated power, rated frequency, rated voltage, rated current, number of phases, power factor and wiring method, etc. (2) Requirements for unit automation functions and performance. (3) Requirements for the structure, performance and installation dimensions of diesel engines, generators and control panels. (4) Requirements for parallel operation of units: If multiple units are purchased at the same time, are they required to be operated in parallel? If parallel operation is required, whether the measuring instruments and devices required for parallel operation need to be provided. (5) Requirements for ancillary equipment of the unit: many manufacturers consider cooling

Many customers do not understand the phenomenon of carbon deposits in generator sets, and do not know how to deal with such a situation. Below, Haixing will explain in detail some common causes of carbon deposits in generator sets. Carbon deposits in generator sets are actually the product of incomplete combustion of diesel and oil that rushes into the combustion chamber. It is a common phenomenon to produce carbon deposits on the top of the diesel engine piston, on the walls of the combustion chamber and around the valves. A large amount of carbon deposits will have a certain impact on the performance of the diesel generator set, causing poor combustion, worsening heat transfer and reducing the reliability of the injector. Several common causes of carbon deposits are: 1. The fuel injector is not working properly, such as poor atomization, oil dripping, diesel generator injection pressure is too high or too low, injection time is too early or too late, and the amount of fuel injection is too much, which will cause incomplete combustion of part of the fuel. . 2． Serious oil leakage. 3. Serious air leakage. 4． Cooling water temperature is too low

Generator set torsional torque The torsional torque output from the flywheel of the generator set is called effective torque, referred to as torque, and its unit is Newton·meter (Nm) or kilogram force·meter (kgf.m). It refers to the heat generated by the combustion of fuel after it is mixed with air in the cylinder, causing the gas to expand and perform work to generate rotational torque, which overcomes the frictional resistance torque of each part and drives various auxiliary devices (such as fuel injection pumps, cooling water pumps, and lighting generators). The torque consumed by the crankshaft is finally transmitted to the flywheel through the crankshaft to provide the torque for use. The force required by the generator set to drive the diesel engine chassis and traction agricultural tools is transmitted to the flywheel and becomes a reaction torque that hinders the rotation of the flywheel, which is usually called the load of the diesel engine. In actual work, the torque transmitted from the flywheel of the generator set should be equal to the load of the diesel engine. The vibration isolation structure diesel generator set adopts a welded base structure, which is made of high-quality medium-thick steel plates and boiler steel plates that are cold-worked and tailor-welded.

According to news, French energy group EDF plans to test four tidal power generating units with a total capacity of 2MW installed near Brea Island on the 31st. EDF introduced that the total investment in the project is nearly 40 million euros, and the company will receive subsidies from the European Union and French environment and energy agency Ademe. The company OpenHydro is responsible for designing the turbine units, while French shipbuilding company DCNS is responsible for assembling the equipment. The turbine generator is a new type of generator that obtains electricity from ocean currents. The energy produced by the tidal turbines will be converted by a set of rectifiers and transported to the mainland via underwater cables. Preparations will be made for the implementation of the project. Local authorities will fully support this development and implementation. What is a tidal generator? Tidal power generation is to build a dam in a bay or a tidal estuary to form a reservoir, and place a hydroelectric generator set in or next to the dam to make use of the rise and fall of the seawater level when the tide rises and falls.

First of all, Haixing will introduce to you what cavitation is. Cavitation corrosion means that the surface of the outer wall of the diesel engine wet cylinder liner in contact with the coolant is destroyed into needle-shaped holes. These holes gradually expand and deepen, and finally form deep holes or cracks; the holes are generally clean and have no corrosion products. Haixing concluded that most people believe that cavitation is caused by high-frequency vibration of the cylinder liner. Mechanical vibration causes changes in coolant pressure, causing bubbles to be generated and burst in the coolant. This process is the cause of cavitation. Since there is gas dissolved in the coolant, when the high-frequency vibration of the cylinder reduces the local pressure of the coolant to a certain critical value, the gas dissolved in the coolant is separated in the form of bubbles, and these bubbles flow to the high-pressure area. Collapse occurs when the pressure exceeds the bubble pressure. The gas in the bubble state is re-liquefied or dissolved in the coolant, and the volume suddenly decreases. The coolant moves towards the center of the bubble at high speed, causing a water hammer phenomenon, resulting in

If the fuel injection pump of the generator set supplies too much fuel, it will increase fuel consumption and easily lead to incomplete combustion, causing wear of the cylinder, piston and piston rings, and even causing overheating and cylinder knocking of the diesel engine. To judge the fuel supply amount, you can open the side cover of the fuel injection pump for detailed inspection based on the smoke exhaust situation. Haixing summarizes the reasons for excessive fuel supply from the fuel injection pump based on past maintenance experience as follows: 1. Adjust the fuel injection pump plunger to obtain the fuel supply volume. It is too large, or the locking screw of the adjusting ring gear is loose and the adjusting gear is displaced, resulting in excessive fuel supply to the fuel injection pump. ②The adjustment screw in the builder 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'. In addition, attention should also be paid to the unstable operation, power reduction, and exhaust gas of the diesel generator set caused by uneven oil supply that may occur during use.

Due to the approaching peak power consumption, the number of companies or individuals purchasing generator sets has generally increased recently. Not all users are skilled in the use of generators.Then, walking into the whole process of generator set operation will help novices use it correctly and safely.The entire operation process of the generator set consists of five parts: preparation before starting, starting, running, shutting down, and maintenance after shutting down. Each part is indispensable.Some users do not do enough preparation work or maintenance work, which can easily cause the unit service life to be shortened or the unit to malfunction. Therefore, Jiangsu Haixing Power needs to remind users to follow the steps and do every step as required, so as to It does not affect electricity consumption and ensures safe use.1. Preparations before starting the generator set 1. Check the lubricating oil level, coolant level, and fuel quantity 2. Check the pipelines and joints of the diesel engine's oil supply, lubrication, cooling and other systems for oil and water leakage 3 2. Check the electrical circuits for leaks such as broken skins etc.

Many provinces are experiencing 'power shortages' before the arrival of summer, and many companies purchase diesel generator sets to prepare for 'power shortages'. Therefore, as summer is coming, Jiangsu Haixing Power reminds customers of the precautions when installing fuel tanks to ensure the safe operation of the unit. Different models of diesel generator sets have corresponding standard fuel tanks and fuel supply systems. There are many types of fuel tank designs, and users can design discrete fuel tanks of various capacities according to requirements. Users can also design their own fuel tanks. When installing the fuel tank of a diesel generator set, users need to pay attention to the following precautions: 1. The fuel tank is stored in a safe location to prevent fire. The fuel tank or oil barrel should be placed separately in a visible place, appropriately away from the diesel generator set. Keep the unit far away, and smoking is strictly prohibited; 2. If the user makes the fuel tank by himself, it should be noted that the fuel tank of the backup diesel generator set is made of stainless steel or steel plate. Do not spray paint or galvanize the inside of the fuel tank, because they will interact with the diesel fuel. A chemical reaction occurs that may

　　Recently, many big cities across the country have experienced serious power shortages. Judging from the National Development and Reform Commission's early warning of 'power shortage' and the current phenomenon of power rationing gradually spreading across the country, this year's 'power shortage' will be very serious. Currently, power shortages and subsequent power rationing have spread across the country. Various companies have purchased generator sets to generate their own electricity to solve the problem of power shortage. Many companies have rarely used generator equipment before, and may not understand some basic operating specifications of generators. We have sorted out the basic operating specifications for the use of the generator set. I hope everyone will strictly follow the operating specifications when using the generator set to ensure power consumption! For generators powered by diesel engines, the operation of the engine part shall be carried out in accordance with the relevant regulations of internal combustion engines. Before starting the generator, you must carefully check whether the wiring of each part is correct, whether the connecting parts are secure, whether the brushes are normal, whether the pressure meets the requirements, and whether the grounding wire is in good condition. before starting
