Looking forward to your inquiry, for more details, please contact us with [email protected]. Today, we will briefly introduce the maintenance method of the water tank of Volvo diesel generators. If anyelse you need to know about that, welcome to visit our Starlight website, and then we will introduce the relevant information to you.
Cleaning of the water radiator: The water radiator needs frequent maintenance to ensure the heat exchange between the coolant and the air. Under normal circumstances, the exterior and interior of the water radiator should be cleaned every 500 hours of Volvo diesel generator work. To clean the internal scale and precipitated impurities, first drain the water in the radiator, and then use clean water with a certain pressure (such as tap water) to pass into the radiator core until the water flowing out is clean. Maintenance of the water radiator: After the water radiator has been used for a period of time, if there is a leak, it can be repaired with solder. When the individual pipes are seriously damaged and cannot be repaired, the pipes are allowed to be blocked, but the number of blocked pipes cannot be more than three, otherwise the water temperature of the Volvo diesel generator may exceed the allowable range. Daily precautions: The pressure cover installed on the water inlet of the water radiator can increase the pressure of the system to a certain range, which not only increases the boiling point of the coolant, but also enables the system to work normally at a higher temperature and a certain altitude. At the same time, the cavitation resistance of Volvo diesel generators and water pumps has also been improved. There is a steam valve and an air valve in the pressure cover. When the positive or negative pressure in the water radiator exceeds the specified value, the valve set in the pressure cover will automatically open to achieve the purpose of steam discharge or air entry. When the Volvo diesel generator is working, the pressure cover should be closed so as not to hinder the normal operation of the cooling system. It is necessary to check the coolant level in the water radiator frequently and replenish it in time. If the liquid level is too low, it will affect the cooling effect of the system and aggravate the cavitation of Volvo diesel generators. At this time, it is necessary to add coolant to the water radiator, but be careful. To prevent the steam from hurting people. Starlight Power has advanced testing equipment, modern production technology, professional manufacturing technology, perfect quality management system, and strong technical research and development capabilities. It can provide 3KW~2500KW various specifications of ordinary, automatic, four protection, automatic switching, low noise and mobile generator sets, high quality and low energy consumption to meet the diverse power needs of customers, and can also meet users with different voltages and different frequencies. It is required to create a parallel power supply system for multiple units. If you are interested in our product or any question on generator, welcome to send email to [email protected]. The piston is an indispensable part of the Volvo diesel generator set. The reciprocating motion in the cylinder transmits the force and completes the working cycle of the diesel engine; the piston, the cylinder head and the cylinder together form the combustion chamber, and the piston group acts as a seal to prevent the gas from penetrating into the crankcase, but also restricts the oil entering the combustion chamber. This paper studies and analyzes the common failures of pistons in diesel engines to make the pistons operate reasonably, efficiently and reliably.
1. Piston skirt wear When the piston is working normally, its skirt and the piston pin seat hole form a vertical working surface. Due to the action of side pressure, it directly rubs with the cylinder wall, and the surface produces regular filamentous wear marks. In general, this wear does not affect the normal fit of the piston to the cylinder wall. When the piston is working, because it is equipped with a piston ring, its head is rarely in contact with the cylinder wall (the diameter of the head is generally smaller than that of the lower part, the difference is about 0.6-0.9mm), and the top is easy to expand because it is heated and the metal is also thicker. Although the skirt is in contact with the cylinder wall, its unit pressure is not large, and the lubrication conditions are good, so the wear is also small. Due to the side pressure generated when the piston and connecting rod are running at high speed, the piston will form radial wear. Therefore, the measure of the availability of the piston depends on the degree of increased clearance between the piston and the cylinder wall. As a result of the increase in the gap between the piston and the cylinder wall, the metal knocking sound (commonly known as the knocking of the cylinder) aggravates the wear of the piston and the cylinder wall, air leakage, poor start-up, unstable speed, decreased power, increased oil consumption, and exhaust gas blue smoke. 2. Piston ring groove wear The piston ring of the Volvo diesel generator set moves in the ring groove, so that the piston ring groove is subject to maximum wear in the height direction, making it step-shaped or trapezoidal (large outside and small inside). The influence of the unit pressure and high temperature of the piston ring on the groove wall is the main cause of wear, and the wear speed of the ring groove depends to a large extent on the roughness of the piston ring plane and the structure of the piston. The side clearance and backlash of the piston ring increase, the oil channeling (fuel leaks into the oil basin), the pumping action increases (the oil participates in the combustion, and the exhaust emits blue smoke), the oil consumption increases, and the power and economy decrease. 3. Piston pin seat hole wear The wear of the piston pin seat hole of Volvo diesel generator set is generally smaller than that of the piston ring groove, and the wear speed depends on the roughness of the piston pin seat hole and the fit of the piston pin and the pin seat hole. Due to the action of gas pressure and inertial force, the wear of the piston pin seat hole is not round, and the largest wear occurs in the direction perpendicular to the piston top (upper and lower of the piston pin seat hole). The fit of the pin hole is loose; the pin rattles; the pin jumps out and breaks the cylinder. In addition, the piston will also produce peripheral wall cracks and scratches and other faults. If the above damage is found, it cannot be used. As a professional diesel generator manufacturer, we always insist on using first-class talents to build a first-class enterprise, create first-class products, create first-class services, and strive to build a first-class domestic enterprise. If you would like to get more information welcome to contact us via [email protected]. The cooling and ventilation of diesel generator set is very important. The machine room shall have sufficient air flow to meet the needs of genset combustion, cooling and ventilation.
1.Cooling requirements 1. When installing diesel generating set, make the radiator close to the exhaust outlet as far as possible to prevent the recirculation of hot air. When there is no air duct, it is recommended that the distance between the radiator and the exhaust outlet should not exceed 150mm. If the machine room is difficult to meet the above requirements, it is recommended to install corresponding air ducts. 2. The area of the air outlet shall be 1.5 times that of the radiator. Generally, the air duct and exhaust louver shall be installed in conjunction with the radiator. 3. The bending of the air duct shall pass through the appropriate elbow. If the pipeline is too long, the size shall be increased to reduce the exhaust back pressure. Long distance air duct silencer shall be specially designed according to the characteristics of the building. 4. The air inlets and outlets of buildings are usually equipped with louvers and grids. When calculating the size of air inlets, the effective ventilation area of louvers and grids shall be considered. 5. A large amount of air is required for genset combustion and cooling, which is often ignored. It is recommended that the total area of air inlet shall be at least twice the heat dissipation area of the diesel generator. All air vents shall be able to prevent rainwater from entering. In cold climate areas, the machine room of standby and rarely operating generator sets shall be able to be insulated. Adjustable louvers can be installed at the air inlet and exhaust outlets. The louvers can be closed when the genset is not running. For diesel generators that are put into operation automatically due to main power failure, it is usually necessary to install standard thermostatically controlled immersion cooling water heaters. 2.Ventilation requirements 1. The damper or shutter can isolate the machine room from the surrounding environment, and its opening and closing operation shall be controlled by the operation state of the unit. 2. The movable damper installed in the machine room in cold areas shall allow the recirculation of air flow in the machine room to heat the machine room when the machine is cold, so as to improve the efficiency of diesel generators. Hope above information is helpful to you when you start to design the diesel generator room. More technical information support and generator set price, welcome to contact us by email [email protected]. The good environment of the diesel generator room plays a very important role in the normal operation of the diesel generator. Therefore, we should pay great attention to the cooling and ventilation measures of the room, so as to ensure the reliability of the power supply of diesel generator. Treatment of cooling water for diesel generator set The cooling system of diesel genset is vulnerable to corrosion and pitting corrosion. In order to reduce the degree of corrosion, anti rust agent should be added to the cooling water. However, it should be noted when adding.The cooling water shall be kept clean and free from chloride, sulfide and acidic chemicals that may cause erosion. Drinking water can be directly used in a bunch of cases, and should be treated according to the following methods: 1) Rust prevention In order to prevent the cooling system from scaling, blocking and rusting, additives (such as Cummins DCA4 or substitute) should be used. Antifreeze shall also be added to the cooling water as appropriate. The use of antifreeze combined with DCA4 can obtain better anti rust and anti pitting protection effect. 2) Treatment method A. Add the required amount of water into the mixing container, and then dissolve the required DCA4. B. If necessary, add antifreeze and mix thoroughly. C. Add the mixed coolant to the cooling system and screw the water tank cover. 3) Protection in cold weather When the coolant is likely to freeze, antifreeze additives should be used to avoid damage to the unit caused by coolant freezing. Recommended usage: 50% antifreeze / 50% water mixture. It is recommended to increase the dose of dca4 under special circumstances. Antifreeze with low silicate content is recommended. 4) Warm up It is recommended to use temperature controlled intrusive cooling system heating device (using mains power) to maintain the temperature of cooling water in cold weather. Diesel generator set is widely used in industrial and agricultural production, national defense, science and technology and daily life. But many customers in the purchase of diesel generator set, in order to save cost, always want to buy the maximum power diesel generator with low cost. In the long-term operation process of diesel generator set, parts will produce certain loss. If it is light, it will affect the safe operation of the unit. If it is serious, it will lead to the normal operation of the unit.
So what kind of loss will diesel generator set produce in the process of operation? 1.When assembling diesel generator set, will install fan water radiator to connect alternator bearing. At this time, the power of the generator set will lose 10% compared with the diesel engine. 2.DC loss. It is the loss of generator stator current through stator winding. 3. Core loss, It is the magnetic loss produced by the generator flux in the generator. It includes three aspects: magnetic loss, eddy current loss and additional loss produced by the main flux in the stator core. 3.Excitation loss. It is the loss of excitation current in the rotor circuit when the generator is running. 4.Additional loss of electrical equipment, loss of leakage flux near the end of generator, loss of harmonic flux, iron loss of sub harmonic and high harmonic on the surface of rotor, etc. 5.Mechanical loss. It refers to the ventilation loss and friction loss of transmission parts during the operation of the generator set. In order to prevent the wear of generator equipment and ensure the safe operation of the equipment, please focus on the regular maintenance of these parts, so as to improve the maintenance quality and extend the service life of the generator set. According to your question, how to optimize the operation of diesel oil generator and reduce energy consumption? There are several ways to reduce energy consumption: 1.Pay attention to that some minerals or impurities, which will precipitate at the bottom of the purified diesel oil tank after it has been used for a period of time, which should be removed or purified regularly. Otherwise, it will have a great impact on the normal operation of the plunger and the fuel injection head, which is easy to cause inaccurate fuel supply time, uneven fuel supply, poor fuel atomization, etc., resulting in increased fuel consumption and decreased power. 2.During the operation of diesel engine, due to the high temperature of relevant components in the combustion process, the ash carbon polymer will adhere to the valve, valve seat, fuel injection nozzle, piston top, etc. if it is not cleaned in time, the fuel consumption will increase and the normal operation of the engine will be seriously affected. Generally, it is best to clean it once every 4-6 months. 3.Don't overload operation. The overload operation of small horse pulling cart type will turn a considerable part of diesel into black smoke, which will not give full play to its effective function, increase fuel consumption and shorten the service life of relevant parts.
