常用、备用、应急柴油发电机组的选择策略 Selection strategy for commonly used, backup, and emergency diesel generator sets

用户在采购柴油发电机组之时，要根据自己的切实情况，以及所处环境等进行采购。众所周知，柴油发电机组可以分为常用、备用、应急柴油发电机组。那么这三种柴油发电机组应该怎么选。

一、常用机组选择

二、备用机组选择

三、应急机组选择

When purchasing diesel generator sets, users should make purchases based on their actual situation and the environment they are in. As is well known, diesel generator sets can be divided into commonly used, standby, and emergency diesel generator sets. So how should these three types of diesel generator sets be selected.

1、 Common Unit Selection

The commonly used diesel generator set refers to the situation where production and life cannot be interrupted in the absence or unstable supply of mains electricity, and therefore diesel generator sets are used as the main power source. Long usage time, high mechanical wear and tear, and high failure rate. In this situation, high-quality diesel generator sets have become the first choice. The quality of domestic first-line brands is beyond doubt. With the development of diesel generator sets, the technology has become very mature, and the difference between domestic and foreign brands is not significant. However, as we are in the information age, we often believe that foreign brands have much better quality than domestic brand diesel generator sets. In fact, domestic brand technology is also very mature, especially durability and practicality, which have surpassed foreign brands in many cases. Of course, purchasing a diesel generator set is purely based on personal preferences and opinions. As a suggestion, the minimum configuration should be a domestic first-line brand diesel engine, and joint venture or imported brands can also be chosen.

2、 Selection of standby units

Backup diesel generator set refers to a temporary power generation unit that operates normally without affecting production and daily life, and is only used for occasional power outages. Low frequency of use, short usage time, low mechanical wear and tear, and low failure rate. In this case, there is no need to blindly pursue units with high-end imported diesel engine configurations. Generally, units with domestically produced diesel engine configurations can fully meet the needs of use. Brand, fuel consumption, noise, failure rate, overhaul time, and so on, these indicators do not need to be considered too much, but one thing needs to be noted, maintenance is essential.

3、 Emergency Unit Selection

Emergency diesel generator sets are generally recommended to use high-speed, turbocharged, low fuel consumption, and same capacity diesel generator sets. High speed turbocharged diesel engines have a larger single unit capacity and occupy less space; Diesel engines are equipped with electronic or hydraulic speed control devices, which have good speed control performance; Synchronous motors with brushless excitation or phase compound excitation devices should be selected for generators, which are reliable, have a low failure rate, and are easy to maintain and repair.
