Diesel Generator Tech

We all know that diesel generators are more fuel-efficient compared to gasoline generators, but after using them for a period of time, there will also be an increase in fuel consumption. As a commonly used   Volvo diesel generator , it also has this problem. So, what should we do if Volvo diesel generators consume more fuel? Today, Dingbo Power takes you to know how to effectively solve the problem of excessive fuel consumption in Volvo diesel generator sets.   The increase in fuel consumption of diesel generator sets is due to the following reasons: 1. The genset is worn out. Normal wear caused by long-term use of the engine, or abnormal wear caused by improper maintenance, can cause longitudinal pulling marks on the cylinder liner of the diesel engine. The cylinder diameter and piston side clearance exceed the specified values, resulting in a corresponding reduction in the support force of the piston rings and unclean oil scraping. 2. There is oil le...

 Do you know why the pressure of diesel engine oil is too high? Today, Dingbo Power takes everyone to understand the reason. The principle of pressure generation in the diesel generator lubrication system by the oil pump indicates that the oil in the lubrication system can generate pressure mainly due to the flow resistance of the oil in the pressure section of the system. The pressure is related to the flow resistance of the engine oil in the system. When the flow resistance of the engine oil in the system is high, the engine oil pressure is high, and when the flow resistance of the oil in the system is small, the engine oil pressure is low. From this, it can be seen that the high engine oil pressure in the lubrication system is inevitably caused by the excessive flow resistance of the engine oil in the system. In addition, the oil pressure display device is malfunctioning and displays an abnormal oil pressure value (i.e., the oil pressure is displayed as too high), leading to the...

Whether it is a domestic or imported diesel generator set, improper use or maintenance may result in oil and water leakage during the use of a 500KW diesel generator set. Diesel generator set manufacturers recommend that users learn to analyze the location of oil and water leakage and then understand the methods to solve this problem. The oil leakage of the  diesel generator set  may be due to the leakage of the oil pan gasket. The possible reasons for oil leakage may be that the purchased or self-made paper pads do not meet the required quality standards, such as insufficient thickness, improper storage, wrinkling and deformation, or lack of attention to cleaning during assembly, which may be contaminated with dust and impurities. The solution to oil leakage from the oil pan gasket of a diesel generator set is to replace the gasket. The method for replacing the oil pan gasket is as follows.   (1) Use a socket wrench or a ring wrench to diagonally remove all the fixing sc...

  A diesel generator turbocharger is an air turbocharger that increases the amount of boost by compressing air, and its function is as follows:   1. Increase the power of the diesel generator set. Under the condition that the displacement of the diesel generator set remains unchanged, increasing the intake air density can allow the diesel engine to inject more fuel, thereby increasing the power of the genset. After installing a turbocharger, the power and torque of the diesel generator set should be increased by 20% to 30%. On the contrary, under the same power output requirements, the cylinder diameter of the genset can be reduced, and the volume and weight of the diesel engine can be reduced.   2. Improve the emissions of the genset. The turbocharger engine reduces the emission of harmful components such as particulate matter and nitrogen oxides in the exhaust gas of the genset by improving the combustion efficiency of the engine. It is an indispensable c...

The function of transformers is to transform voltage, isolate electrical equipment, stabilize voltage, etc. It can ensure the stable operation of electrical equipment under different load conditions, and also protect the safety of electrical equipment. When the transformer of the diesel generator set is running, it is necessary to maintain the normal fuel level. During use, we should check the indication of the fuel level gauge on time. When the fuel level is too high (such as in summer), the fuel should be drained in a timely manner; When the fuel level is too low (such as in winter), it should be replenished in a timely manner to maintain the normal fuel level and ensure the safe operation of the transformer. 1. The fuel level is too high. The fuel level rises above the maximum fuel level line due to an increase in fuel temperature, and sometimes the fuel level reaches the top without being visible. The reason for the high fuel level is that the transformer cooler operates abnormally...

What is the fully automatic parallel cabinet project for diesel generators? The principle of fully automatic parallel operation is that after several generators are connected, they are equivalent to a high-power generator supplying power to the load. The number of generators can be determined according to the size of the load (the unit consumes the lowest fuel at 75% of the rated load), thus achieving the goal of saving diesel and reducing the cost of diesel generators. Realize uninterrupted power supply to ensure normal production of the factory. When the unit is converted for use, the backup unit can be integrated into the operating system, and then all the load can be transferred to the already running backup unit before stopping the original operating unit. There is no need to cut off power halfway. Multiple units operate in parallel. When the load suddenly increases, the current surge is evenly distributed among the multiple units, reducing the force on each unit and stabilizing t...

This article continues to introduce the working principle and structural characteristics of the engine water pump for   diesel generator   users. The water pump shaft is supported on the housing with two bearings, which are filled with lubricating grease and positioned with a spacer between the bearings. The front end of the front bearing has a retaining ring to fix the bearing and prevent the axial force generated by the fan rotation from moving the pump shaft forward. The pump shaft is equipped with a water throwing ring. When the water seal leaks, the water seeping forward is blocked by the water throwing ring and thrown towards the inspection hole to prevent damage to the bearing. In order to reduce the burden on the water throwing ring, a water blocking groove is installed on the pump shaft (between the water throwing ring and the water seal). The bearing is single-sided sealed, and the surface with oil seal should be installed facing both ends of the shaft. When the oil ...

Simply put, the function of the engine water pump in a diesel generator set is to cool the engine and prevent it from overheating and breaking down. The working principle of the  diesel engine  water pump is to drive the water pump bearing and impeller to rotate through the pulley. The coolant in the water pump is driven by the impeller to rotate together, and is thrown towards the edge of the water pump housing under the action of centrifugal force, while generating a certain pressure, and then flows out from the outlet or water pipe. At the center of the impeller, the pressure decreases due to the coolant being thrown out. The coolant in the water tank is sucked into the impeller through the water pipe under the pressure difference between the inlet of the water pump and the center of the impeller, achieving the reciprocating circulation of the coolant.   The structural characteristics of the engine water pump:   The engine water pump is composed of the pump housin...

The radiator of a diesel generator is an important component of the generator set, and its main function is to remove the heat generated by the diesel generator through heat dissipation, maintaining the normal operating temperature of the generator. A heat sink is usually composed of heat dissipation pipes, fins, and fans.   The working principle of a diesel generator radiator is to use coolant (usually water) to circulate in the heat dissipation pipe, transfer heat to the air through the heat dissipation fins, and exhaust the hot air through the fan. When a  diesel generator  is working, its engine will generate a large amount of heat. If it cannot dissipate heat in a timely manner, it will cause the generator to overheat and affect its normal operation. Therefore, the performance of the radiator directly affects the efficiency and reliability of the diesel generator.   During the operation of a silent diesel generator set, the coolant in the heat dissipation tank i...

This article continues to introduce the remaining three parts of diesel engine pistons. 3. Piston pin seat   The pin seat is used to install piston pins, mainly for transmitting air pressure. There are often reinforcing ribs between the piston pin seat and the top to increase stiffness. The pin seat hole is equipped with a ring groove for installing an elastic snap ring. The piston pin snap ring is used to prevent axial movement of the piston pin during operation, which may cause damage to the cylinder block by protruding out of the piston pin seat hole.   4. Skirt   The part below the lowest oil ring groove on the piston head is called the skirt. Its main function is to guide the movement of the piston inside the cylinder, and it also bears lateral pressure. Due to the high gas pressure and side pressure of diesel engines, the skirt is also relatively long to reduce pressure and wear per unit area. Lateral pressure refers to the horizontal component of gas pressure actin...

  1. Precautions when starting Cummins diesel engine generator   (1) Before starting Cummins diesel engine generator, the starting system circuit and the charging condition of the battery must be checked first. When starting, check whether the battery terminal and battery clip are secure.   (2) When starting a diesel engine, if one start cannot achieve the starting purpose, the interval between the second start and the first start should not be less than 2 minutes.   (3) Quality requirements for starters, batteries, and battery cables. Each start time is not allowed to exceed 10 seconds. If  diesel generator set  is started, the hand should be quickly separated from the start button to prevent the failure of the swing wheel and flywheel after the diesel generator set is started.   (4) When the diesel generator set fails to start for several consecutive times, the fault that caused the inability to start should be eliminated before starting.  ...
