WINDING PROTECTION IS A KEY ISSUE WHEN USING GENERATOR SETS Generator system： •Anti-condensation space heaters • Coastal Insulation protectio DEMANDING ENVIRONMENTS Environmental stress is usually classified according to four criteria: •Humidity is a problem because it is an electrical conductor. It is therefore likely to encourage the development of potential short-circuits. Moreover, moisture tends to accumulate in the bottom of the machine, where it mixes with dust and does even more damage to the windings Dust and other particlesconstitute another hazard, as they cause mechanical abrasion of the varnish, which will gradually lead to a Xiamen ZTA Power System Co.,Ltd Power system supplier-Generator sets, Lighting Tower, Reefer Genset Add: Room C5, No. 113, Chengyi North Street, Software Park III, Torch High-tech Zone, Xiamen,China.

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 protection fun...

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.

What are the precautions for the design of exhaust system of Diesel generator exhaust system The exhaust of Diesel generator is not only harmful but also high temperature, so the design of exhaust system should be paid special attention If the back pressure of the exhaust system on the engine exceeds the specified value, the performance of the engine will be affected and the maintenance interval will be shortened The shorter the exhaust system, the smaller the resistance (and back pressure), and the bending parts within the system have a significant impact on the resistance. The maximum allowable resistance of the exhaust system is R=450 mmH20: All models except SR.6D 600 mmH20: SR 816 mmH20: 6D The resistance is measured at the outlet of the turbocharger The recommended material for the exhaust pipe is carbon steel pipe (non galvanized) 1.1 Calculation of exhaust resistance and determination of exhaust pipe diameter The exhaust resistance is affected by exhaust pipelines and silencers, etc The exhaust resistance of the pipeline is obtained from the following equation Pipe Diameter Insisde Diameter External Diameter A B 150 200 250 300 350 400 450 500 6 8 10 12 14 16 18 20 155.2 204.7 254.2 304.7 339.8 390.6 441.4 492.2 165.2 216.3 267.4 318.5 355.6 406.4 457.2 508.0
