As an important equipment in the daily work of the enterprise, the efficiency of the diesel generator set has a great impact on the enterprise. Therefore, the diesel generator set with good performance is indispensable. What should the enterprise pay attention to when purchasing the diesel generator set? Here are eight pitfalls to avoid when purchasing diesel generator sets.

一、看清楚是否是二手机翻新机，有一些商家把二手机翻新机当作全新机卖给客户，还有的将翻新的柴油发电机配上全新的发电机及控制柜，使一般非专用户根本分不清究竟是新机还是旧机。因此需要了解清楚。

1、 See if it is a second mobile phone refurbishment machine. Some businesses sell the second mobile phone refurbishment machine to customers as a brand new machine. Others match the refurbished diesel generator with a brand new generator and control cabinet, so that ordinary non dedicated users simply can not tell whether it is a new machine or an old machine. Therefore, it needs to be understood clearly.

二、混淆KVA和KW的关系。把KVA当成KW夸大功率，卖给客户。实际上KVA是视在功率，KW是有*功率，他们之间的关系为IKVA=0.8KW。进口机组一般用KVA表示功率单位，而国内用电设备一般都用KW表示，所以核算功率时应把KVA打8折换算成KW。

2、 Confuse the relationship between KVA and kW. Regard KVA as kW, exaggerate power and sell it to customers. In fact, KVA is the apparent power, kW is the * power, and the relationship between them is ikva=0.8kw. Imported units are generally expressed in KVA, while domestic electrical equipment is generally expressed in kW. Therefore, when calculating power, KVA should be converted into kW at a discount of 20%.

三、柴油发电机组功率与发电机的功率配置成一样大，以求降低成本。实际上，业内一般规定柴油发电机功率≥发电机功率10%，因为机械损耗。这是有一些商家还有把柴油发电机马力当作千瓦误报给用户，及用小于发电机功率的柴油发电机来配置机组。

3、 The power of the diesel generator set is configured as large as that of the generator in order to reduce the cost. In fact, the industry generally stipulates that the power of diesel generator is ≥ 10% of generator power because of mechanical loss. Some businesses mistakenly report the horsepower of diesel generators to users as kilowatts, and use diesel generators less than the generator power to configure units.

四、只报柴油发电机或发电机，不报产地，不报机组。如美国康明斯、瑞典volvo、英国史坦福。实际上任何一台柴油发电机组均不可能由一家企业独立完成。客户应了解机组的柴油发电机、发电机、控制柜制造厂家及，才能综合评估出机组的档次。

4、 Only the diesel generator or generator brand shall be reported, and the place of origin and unit brand shall not be reported. Such as Cummins in the United States, Volvo in Sweden and Stanford in the United Kingdom. In fact, it is impossible for any diesel generator set to be completed independently by one enterprise. The customer should know the manufacturer and brand of diesel generator, generator and control cabinet of the unit, so as to comprehensively evaluate the grade of the unit.

五、额定功率和后备功率的关系，仅说一个“功率”，把后备功率当作长行功率卖给客户。实际上，后备功率=1.1ｘ长行功率。而且，后备功率只能在12小时连续运行中使用1小时。

5、 The relationship between rated power and backup power is only one "power", and the backup power is sold to customers as long-distance power. In fact, backup power =1.1x long line power. Moreover, the backup power can only be used for 1 hour in 12 hours of continuous operation.

六、看清楚随机配件的情况，如带不带消音器、油箱、输油管，带什么档次电瓶、多大容量电瓶、几个电瓶等等。实际上，这些附件十分重要，在合同中写明。更有甚者连水箱风扇都不带，让客户自搞开式水池。

6、 See the attached accessories clearly, such as with or without silencer, fuel tank, oil pipeline, battery of what grade, how large capacity, and how many batteries. In fact, these annexes are very important and should be stated in the contract. What's more, they don't even bring a water tank fan, so the customer can make an open pool by himself.

七、不谈柴油发电机及发电机的档次、控制系统配置，不谈售后服务，一味只谈价格及交货期。有的还将非电站专用油机，如：船用柴油发电机，车用柴油发电机用于柴油发电机组。使机组的终端产品—-电的质量无法得以保证。

7、 It doesn't talk about the brand and grade of the diesel generator, the control system configuration, or the after-sales service. It just talks about the price and delivery date. Some also use non power station special oil engines, such as marine diesel generators and vehicle diesel generators for diesel generator sets. The quality of power, the terminal product of the unit, cannot be guaranteed.

作为重要的备用电源设备，在如此紧张的供电情况下，为企业的生产制造提供了很大的方便，因此在购置时一定要谨慎，使用时才能够更加的得心应手。

As an important standby power supply equipment, it provides great convenience for the production and manufacturing of enterprises in such a tight power supply situation. Therefore, we must be careful when purchasing and use it more skillfully.
