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、看清楚是否是二手機(jī)翻新機(jī)，有一些商家把二手機(jī)翻新機(jī)當(dāng)作全新機(jī)賣(mài)給客戶(hù)，還有的將翻新的柴油發(fā)電機(jī)配上全新的發(fā)電機(jī)及控制柜，使一般非專(zhuān)用戶(hù)根本分不清究竟是新機(jī)還是舊機(jī)。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的關(guān)系。把KVA當(dāng)成KW夸大功率，賣(mài)給客戶(hù)。實(shí)際上KVA是視在功率，KW是有*功率，他們之間的關(guān)系為IKVA=0.8KW。進(jìn)口機(jī)組一般用KVA表示功率單位，而國(guó)內(nèi)用電設(shè)備一般都用KW表示，所以核算功率時(shí)應(yīng)把KVA打8折換算成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、柴油發(fā)電機(jī)組功率與發(fā)電機(jī)的功率配置成一樣大，以求降低成本。實(shí)際上，業(yè)內(nèi)一般規(guī)定柴油發(fā)電機(jī)功率≥發(fā)電機(jī)功率10%，因?yàn)闄C(jī)械損耗。這是有一些商家還有把柴油發(fā)電機(jī)馬力當(dāng)作千瓦誤報(bào)給用戶(hù)，及用小于發(fā)電機(jī)功率的柴油發(fā)電機(jī)來(lái)配置機(jī)組。

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、只報(bào)柴油發(fā)電機(jī)或發(fā)電機(jī)，不報(bào)產(chǎn)地，不報(bào)機(jī)組。如美國(guó)康明斯、瑞典volvo、英國(guó)史坦福。實(shí)際上任何一臺(tái)柴油發(fā)電機(jī)組均不可能由一家企業(yè)獨(dú)立完成?？蛻?hù)應(yīng)了解機(jī)組的柴油發(fā)電機(jī)、發(fā)電機(jī)、控制柜制造廠(chǎng)家及，才能綜合評(píng)估出機(jī)組的檔次。

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、額定功率和后備功率的關(guān)系，僅說(shuō)一個(gè)“功率”，把后備功率當(dāng)作長(zhǎng)行功率賣(mài)給客戶(hù)。實(shí)際上，后備功率=1.1ｘ長(zhǎng)行功率。而且，后備功率只能在12小時(shí)連續(xù)運(yùn)行中使用1小時(shí)。

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、看清楚隨機(jī)配件的情況，如帶不帶消音器、油箱、輸油管，帶什么檔次電瓶、多大容量電瓶、幾個(gè)電瓶等等。實(shí)際上，這些附件十分重要，在合同中寫(xiě)明。更有甚者連水箱風(fēng)扇都不帶，讓客戶(hù)自搞開(kāi)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、不談柴油發(fā)電機(jī)及發(fā)電機(jī)的檔次、控制系統(tǒng)配置，不談售后服務(wù)，一味只談價(jià)格及交貨期。有的還將非電站專(zhuān)用油機(jī)，如：船用柴油發(fā)電機(jī)，車(chē)用柴油發(fā)電機(jī)用于柴油發(fā)電機(jī)組。使機(jī)組的終端產(chǎn)品—-電的質(zhì)量無(wú)法得以保證。

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.

作為重要的備用電源設(shè)備，在如此緊張的供電情況下，為企業(yè)的生產(chǎn)制造提供了很大的方便，因此在購(gòu)置時(shí)一定要謹(jǐn)慎，使用時(shí)才能夠更加的得心應(yīng)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.
