Selection of enterprise-owned diesel generator capacity There is currently no unified calculation formula in the country for selecting the capacity of self-provided diesel generator sets, so the methods used by designers in actual work are also different: some simply determine it based on 10%-20% of the power transformer capacity; Some are added according to the capacity of fire-fighting equipment; some are selected according to the wishes of investors, which results in inaccuracy in selecting the capacity of self-provided generating units. If the capacity is selected too large, it will cause a waste of investment; if the capacity is selected too small, it will cause a waste of investment in the event of an accident. Cannot meet usage requirements. So, how to choose the capacity of self-provided generating units? After reviewing the information and referring 

 1. Composition and classification of diesel generators Diesel generator sets for AC power supply, backup and emergency power generation are widely used in many fields of the national economy such as ships and communications. In recent years, the power shortage caused by economic development and uneven resource distribution, especially in the southern coastal areas, has further highlighted the role of diesel generators in the development of the national economy. From hand-started and manned ordinary units to the direction of automation (self-starting, unattended, remote control, remote signaling, telemetry), low emissions and low noise, the technical equipment level of diesel generator sets is constantly improving. Modern diesel generator sets have the characteristics of flexibility, convenience, high degree of automation, low noise and low emissions. With the continuous development of science and technology, the application of some new technologies and new achievements has made modern diesel generator sets have higher intensification, reliability, stability and good emission characteristics, etc., and continue to meet the higher requirements of modern society. (1) Composition Diesel generator set is a type of internal combustion generator set, consisting of a diesel engine, a three-phase AC synchronous generator and a control system (including automatic detection, control and protection devices). The diesel engine, generator and control system (box) of the mobile diesel generator set are all assembled on a common base; while the diesel engine and generator of the larger power stationary unit are installed on a common base welded from steel, and Fixed on a specially designed reinforced concrete foundation, equipment such as the control system and fuel tank of this unit are usually installed separately from the unit. The flywheel housing of the diesel generator and the front end cover of the generator are directly connected in the axial direction using a shoulder positioning method to form an integrated body, and a cylindrical elastic coupling is used to directly drive the generator to rotate through the flywheel. This connection method is fixed together by screws, so that the two are connected into one body, ensuring that the concentricity of the crankshaft of the diesel engine and the rotor of the generator is within the specified range. In order to reduce the noise, diesel generator sets generally need to be installed with special mufflers. In special cases, the unit needs to be fully shielded. In order to reduce the vibration of the unit, shock absorbers or rubber shock absorbing pads are usually installed at the connections between the main components such as the diesel engine, generator, water tank and electrical control box and the public chassis. (2) Classification and functions There are many types of diesel generator sets, which can be divided into the following types according to their structural types, control methods and protecti...

How to Check the Working Quality of Cummins Diesel Generator Governor 1.Maintain standards The internal parts of the speed regulator are not allowed to be stuck during operation. The movement of various parts must be flexible, and the matching clearance between parts must meet the technical requirements. 2. Maintenance methods (1) Inspection and maintenance of speed regulating rotor parts: 1) When the flying iron frame and bracket rotate, there should be no jamming phenomenon. The rotor bearing is not allowed to be too loose or blocked or burned out. Otherwise, new parts should be replaced. 2) When the wear of the inner end of the fly iron exceeds 0.3 minutes, it should be repaired by welding repair. 3) When the matching gap between the flying iron seat frame bushing and the telescopic shaft exceeds 0.22mm, the bushing should be replaced with a new one. After the bushing is pressed in, it should be hinged with the telescopic shaft to ensure the matching size with the telescopic shaft. (2) Inspection and maintenance of speed control gear components. . The mating surface of the speed control gear sleeve is not allowed to have major scratches and eccentric wear. When the buffer spring is not equipped, the two should be able to rotate freely. If the buffer spring is found to be greatly deformed or damaged or broken during inspection, it should be replaced with new parts. When the buffer spring is in a free state, there should be a certain gap between the groups, and the gap between each piece should be less than 0.2mm. The transition arc and straight part of the assembled buffer spring should fit closely with the flange of the speed control gear and the shaft sleeve, and the contact length with the outer diameter of the bearing should be greater than half of the circumferential length.  

It's essential to understand the power requirements of your DC load to properly size the power supply and estimate energy consumption. Additionally, efficiency factors may need to be considered, especially if the load operates intermittently or at varying power levels. Diesel generator sets have been widely used in industrial and agricultural production, science and technology, and daily life. However, when purchasing diesel generator sets, many customers always hope to purchase high-power diesel generators in order to save costs. During the long-term operation of the diesel generator set, the parts and components will produce a certain amount of loss. If it is light, it will affect the safe operation of the unit. If it is serious, it will cause the unit to fail to operate normally. So what losses will the diesel generator set produce during operation? Mobile/wechat/whatsapp：0086-13906008114

Do you distinguish between light fuel storage and "firewood storage" hybrid? As global climate change intensifies and climate governance processes accelerate, "double carbon" actions have become the core of global concern. Climate change directly affects fuel supply, energy production, and the actual resilience of current and future energy infrastructure. The current carbon neutral paths of various developed economies focus on energy transition, using diversified policy tools, focusing on low-carbon, Carbon-negative technological innovation, among which energy storage microgrid technology is the key to achieving the "double carbon" goal of the power system.

How to resist interference in alternators Generator Set Alternator interference may have a certain impact on circuits and systems. The following are some common methods to deal with motor interference: Shielding: Shielding, such as a metal casing or shielded wire, can be added around a circuit or system to prevent electromagnetic waves radiated by the alternator from entering the circuit or system. Filtering: Add appropriate filters, such as low-pass filters or band-stop filters, to the circuit to remove high-frequency components caused by motor interference. Grounding: Proper grounding can reduce the impact of motor interference on circuits and systems. For example, before grounding, you should determine the grounding point and avoid high impedance in the ground loop. Cable routing: When routing cables, attention should be paid to the route and distance of the cables to reduce the impact of electromagnetic interference. You can use methods such as staying away from the motor, reducing the length of the cable, and avoiding parallel wiring as much as possible. Protection: For high-precision circuits and systems, protective measures such as metal shielding boxes and shielding covers can be used to reduce the impact of motor interference. Special devices: There are some special devices that can be used to resist motor interference, such as differential mode amplifiers, optocoupler isolators, etc. These methods can be used individually or in combination, depending on the circumstances. Voltage stabilization: Add voltage stabilizing devices, such as voltage stabilizing diodes, voltage stabilizing chips, etc., to the circuit to ensure the stability of the circuit power supply and reduce the impact of motor interference. Feedback: Adding a feedback control loop to the system can adjust the motor control signal in real time according to the system output signal to reduce the impact of motor interference. Isolation: Use isolation technology, such as photoelectric isolation, transformer isolation, etc., to isolate interference between circuits and systems and motors. Design: Consider the impact of motor interference in circuit and system design, and adopt reasonable circuit and system design solutions, such as reducing the number of coils and motor current, to reduce the impact of motor interference. It should be noted that the above method does not completely eliminate the impact of alternator interference, but only reduces the impact of alternator interference. In practical applications, multiple factors should be considered comprehensively and appropriate measures should be taken to reduce the impact of motor interference. Additionally, there are some common methods for specific types of motor interference: Stepper generator interference: Use higher power supply voltage, reduce generator current, reduce step angle, improve the design of stepper generator driver, etc. to reduce stepper motor interference. Brushless DC alternator interference: Use higher ...
