Diesel Generator Tech

The lubrication method for variable pitch reducers of generator sets is generally immersion lubrication and grease lubrication. After every 6 months of operation of the generator set, the oil quality should be checked as follows: observe the presence of water and emulsion in the oil; Check the viscosity of the oil, and if the difference exceeds 20% or decreases by 15% compared to the original, it indicates that the oil is ineffective; Check the insoluble content, which should not exceed 0.2%, and conduct an anti emulsification ability test to discover whether the oil has deteriorated; Check if the additive composition has decreased. If there are any problems, the oil should be changed or filtered. When changing the oil, the oil is discharged from the oil drain hole and then injected into the oil injection hole. When installing the plug, thread sealant should be applied to the thread. The lubrication system should be kept clean, and measures should be taken to prevent dust, moisture, an...

In the maintenance of Volvo diesel generator sets, due to the high purchase cost of some spare parts or defects caused by casting production, welding repair technology can be used to repair successful cases, which is the main significance of welding repair. In this article, Dingbo   Power Generation   Equipment will talk to you about the specific significance of welding and repairing spare parts. Welding repair of Volvo diesel generator set refers to the application of welding technology to the maintenance of unit equipment. Welding repair causes the matrix and welding rod powder to melt together under the action of thermal energy and achieve good intergranular bonding, with high bonding strength. However, the influence of thermal energy can cause changes in the structure and shape of the matrix, which is a key issue in welding repair. According to the different ways of providing heat energy, welding repair can be divided into Arc welding, gas welding and plasma welding. Accor...

We can only carry out maintenance operations on the generator after it stops operating. Before maintenance, it is not only necessary to disconnect the starting circuit of the prime mover and the connection of the battery, but also the closed circuit between the power grid and other generators to ensure the normal and safe operation of the diesel generator set. 1. Quarterly inspection: During the quarterly inspection, the  generator set  needs to be at a load of over 70% to operate for one hour to burn out the mixture of diesel and oil in the cylinder. 2. Daily inspection: During the daily inspection, it is necessary to check the external parts of the generator set and the battery for any leakage or liquid leakage. Check and record the voltage value of the battery and the temperature of the cylinder liner water. In addition, it is necessary to check whether the heater for the cylinder liner water, the charger for the battery, and the dehumidifier heater are operating normally. ...

Diesel generator set is a diesel engine that extinguishes diesel oil to obtain energy release. The advantages of diesel generator set are high power and good economic performance. The operation of the Diesel generator is similar to that of the diesel generator set. Each operation cycle goes through four strokes: intake, compression, and exhaust. However, since the fuel used for diesel generator set  diesel engine  is diesel, its viscosity is larger than that of joint venture Cummins, and it is not easy to evaporate, and its Autoignition temperature is lower than that of Cummins, so the formation and incineration method of combustible mixture are not the same as those of Sino US joint venture Cummins. The main difference is that the mixture in the cylinder of a diesel engine is compression ignition, rather than ignition. When the diesel generator set is running, the atmosphere enters the cylinder. When the air in the cylinder is compressed to the end point, the temperature can ...

The diesel generator is a kind of power equipment that takes the diesel engine as the prime mover and drives the synchronous diesel generator to generate electricity. This is a kind of Diesel generator generating device with quick start, convenient operation and maintenance, low investment and strong adaptability to the environment. Remove the water stain, oil stain, iron embroidery and other sundries attached to the diesel generator. Make a comprehensive inspection tour of all devices of the  diesel generator , check whether all the connection, fastening and control parts of the diesel generator have been firmly connected, and the nuts of the serial Diesel generator shock absorber shall not be tightened too tightly, otherwise the shock absorption of the diesel generator will become invalid. Check whether the fuel storage capacity in the oil tank of the diesel generator meets the requirements, whether the oil volume in the oil pan of the diesel generator, the fuel injecti...

  Regarding the function of diesel generator filter, some customers have the wrong concept, thinking that the filter is optional, or it is relatively sloppy in maintenance. To sum up, we think that everyone must first clarify a concept that the filter is very important, and then pay attention to the following three maintenance aspects that are easily neglected: 1. Some users lose the upper and lower sealing rubber gaskets and oil cover of the filter element when maintaining the filter of the  diesel generator set , so that the diesel oil does not pass through the filter element and flows into the filter without resistance from the gap between the filter element and the filter cover. The inner cavity of the filter element makes the diesel filter lose its filtering and purification effect. 2. Some users reverse the positions of the trays and springs of the diesel generator set filter, or even throw them away, so that the oil inlet and outlet holes on the diesel filter cover are ...

The working and control principles of the emergency generator set are similar to those of the main generator. For the alarm aspect, there are emergency generators with the same overspeed shutdown as the generators, but the low pressure of the diesel engine oil and the high temperature of the cooling water only alarm and do not stop; the starter must have at least two kinds of energy, usually electric and hydraulic or spring manual start; burning With diesel (in order to save costs, the main generator often uses heavy diesel oil), the diesel cabinet is set to a high alarm. In order to prevent the diesel spill from jeopardizing the safety of the built-up area, high and high alarms are often set; because it is usually an electric starter, it is also equipped with special Starter battery and charge and discharge board. In order to ensure that the state of the emergency generator can be monitored in the engine room under normal working conditions, the operation indication of the emergency...

According to statistics released by Dongfeng, over 110,000 units Dongfeng vehicles, ranging from heavy-duty truck, medium trucks, light trucks, mini-trucks to special vehicles, are working smoothly in African continent. According to Dongfeng Xiangyang Touring Car Co., Ltd., the company is racing against the clock to produce new city buses and chassis for its customer in Egypt. As early as 2006, the company exported its first batch of buses to Egypt. Later, it set up cooperative ties with a local company and thus significantly increased its export volume to the country through CKD. So far, over 3,000 units Dongfeng buses have made their way to Egypt. In addition, Dongfeng (Shiyan) Special Vehicle Co., Ltd. has exported a fairly large number of trucks for transporting water and garbage to Africa. In 2014, Dongfeng Liuqi delivered 103 units Chenglong self-dumping trucks to its customer in Ethiopia. Since the launch of Belt Road Initiative five years ago, Dongfe...

Installation checks for Volvo Engine Installation recommendations regarding each subject are to be found in the previous chapter. Refer to the relevant section to retrieve information so that the installation achieves a satisfactory standard. While the preliminary cooling system design is based on calculations, the suitability of any given system must be determined by actual tests. The tests must correspond to the most difficult operational conditions that may arise during use. Optional equipment specified by the original equipment manufacturer must be clearly defined and taken into account during the tests. Moreover, the checks and tests must include, and be adapted to, such equipment. For high altitude operations, there will be additional costs for the original equipment manufacturer in regard to certain applications. Experience has however shown that if customers are not able to clearly define and check which areas the equipment will be used in, Volvo Penta recommendation...
