Repair technology is one of the three basic technologies for mechanical equipment maintenance. Reasonable selection and application of repair technology is an effective measure to improve the maintenance quality of diesel generator sets, save resources, shorten downtime and reduce maintenance costs. There are many repairing methods for parts. Through long-term practice, mechanical processing, pressure processing, metal-spraying, welding repair, electroplating and-bonding are commonly used in production.
The working condition of the diesel generator set cylinder liner can be said to be “the dirtiest and most tiring”, which plays the role of purifying and isolating pollution. Its working condition directly affects the normal operation of the diesel generator set. If it is used improperly, it will cause serious wear and tear. Damages such as holding cylinders and cavities, and even serious accidents. The following will give you a brief introduction to the structural principle of the diesel generator set cylinder liner.
Synchronous Generator, that is, an alternator (AC generator) with the same rotor speed as the rotating magnetic field of the stator. According to the structure, it can be divided into two types: rotating armature and rotating magnetic field.
Static stability is only a requirement for parallel operation of the generator, and it does not indicates the ability of the system to maintain synchronous operation in the event of a sharp disturbance. Take the short circuit in the grid as an example to illustrate this problem. When the power grid is short circuited, the power angle characteristics of each generator and its output power will suddenly change. For example, a short circuit occurs near the busbar, the bus voltage is close to zero, and the generators are completely lost in contact and influence.
