Diesel Generator Tech

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 300kw 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 300kw 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 as...

The ventilation environment of a diesel generator se t is an important condition to ensure its working environment temperature. However, in order to ensure good ventilation, dustproof measures must be taken, which requires   certain requirements on ventilation. So what are the ventilation requirements of the diesel generating set?   1. Ventilation requirements for diesel generator set Space The location of the generator room should be as far away from the residential area as possible to reduce the impact of the noise and emissions of the unit on the residents. The generator room should be built on an open site as far as possible to facilitate the access and ventilation and heat dissipation of the unit and accessories. The space of the machine room should fully consider the volume of the unit and accessories to ensure that the unit and accessories have sufficient installation space.   Dust-proof design   Good ventilation, dust-proof performance will in...

To the person whom needs diesel generator set, they may meet some problem. The first problem is that whether it is better to rent diesel generators or not. It's also expected to get you involved in this problem. The problem seems very difficult. In fact, we can consider it from our own situation. Renting or buying diesel generator set all is to solve the problem of standby power supply. If you buy a diesel generator set by yourself, you will have the right to use it, and you put it on the place you need for a long time. If there is a blackout, the diesel generator set can immediately supply power as a standby power supply, so that you don't need to contact the leasing company. It greatly shortens the time of power supply, it can reduce the risk brought to enterprises by unexpected situations. This is a suggestion from a factory who produced 600kw diesel generator set, not as a final decision to buy generators, it depends on your requirement. But whatever buy g...

4.4 Commissioning and operation of Siemens generator (alternator) 4.4.1 Commissioning The following checks are essential before the driving machine is commissioned; - The generator load must be disconnected. - the insulation resistance must have at least the specified value. - All the safety rules for operation of the generating set must be observed. - The protective earth conductor must be connected. After these checks, the complete generating sets can be started up in the accordance with the instructions. Providing the generator has not been out of service for more than three months, a brief visual inspection is sufficient before is started up again. 4.4.2 Changing the direction of rotation The generator is equipped with one fan for both directions of rotation. If the direction of rotation is changed, the phase sequence at the main terminal is also changed. 4.4.3 Operation Note: Deviations from the normal performance (higher power input, hig...

Engine speed regulator, adjustment The regulator has a factory setting that has been optimized to suit the most common generator set applications. Use the VODIA tool (including EMS software), to read and adjust the P, I and D sections of the engine speed regulator. Adjustment is done to obtain more stable and even engine running, and to configure the engine for specific generating set applications. PID = Proportional, Integrating, Differentiating P-value amplifier (Gain), amplification of the difference between the actual value and the set value. A reduced value (Fig. 1) gives a weaker reaction to engine speed differences. Reduce the P-value to reduce oscillations arising from large differences in speed/load application. An increased value (Fig. 2) gives a shorter response time. Increase the P section for faster compensation to large differences in engine speed/engine loading. I-value stabilizes (Stability), reacts to the time of the speed deviation. A reduced valu...

Diesel Electric Generator Set  Many years experience on diesel engine generator design and production enable this machine to supply with improved efficacy and stable high quality power This manual of technical operation and maintenance provides users with methods for maintenance and operation. Applied with the reference to diesel manual and alternator manual, this manual could ensure this   electric generator a long-term high effective operation. It must   be attention that frequent maintenance is required under dirty or dusty environment in order to ensure regular operation. Ensure to have the special trained professionals to implement adjustment and maintenance for this generator. Each electric generator casing has a piece of name board on which displays the type and   number of the generating set. These numbers were required when order replacement parts or after service. Security 2.1 General description The generator is extremely...
