What are the precautions when buying a diesel generator?

When customers purchase diesel generators, they definitely want to buy their own attractive products at a lower price. Some merchants use the customer's inexperienced customers to deliberately raise the utility of the unit or conceal some of the conditions during the customer's purchase process. This sets up a purchase trap. So today, Yangzhou Shengfeng has put together some traps for the purchase of diesel generator sets for reference during the purchase.

1, only reported diesel engine or generator brand, do not report origin, do not report the unit brand. Such as the United States Cummins, Sweden volvo, the United Kingdom Stanford. In fact, any diesel generator set cannot be completed by a single company. The customer needs to fully understand the diesel engine, generator and control cabinet manufacturer and brand of the unit so as to comprehensively evaluate the grade of the unit.

2. The second mobile phone refurbished machine is sold as a new machine to customers, and some refurbished diesel engines are equipped with new generators and control cabinets so that non-professional users can hardly tell whether they are new or used machines.

3, do not talk about the relationship between rated power and backup power, just say a "power", the backup power is sold to customers as long-term power. In fact, backup power = 1.1x long line power. Also, backup power can only be used for 1 hour in 12-hour continuous operation.

4. Units that do not have protective functions (commonly known as four protections) are sold to customers as fully-protected units. What's more, it sells units with incomplete instruments and no air switches to customers. In fact, the industry generally stipulates that the unit above 10KW must be equipped with full instruments (commonly known as five tables) and air switches; large-sized units and automatic units must have self-protection function.

5. Confuse the relationship between KVA and KW. Think of KVA as KW exaggerating power and selling it to customers. Actually, KVA is the apparent power and KW is the effective power. The relationship between them is IKVA=0.8KW. Imported units generally use KVA to denote power units, while domestic power equipment generally uses KW. Therefore, when calculating power, KVA should be converted by 20% to KW.

6, diesel engine power and generator power configuration is the same, in order to reduce costs. In fact, the industry generally stipulates that the diesel engine power ≥ the generator power 10% because of mechanical losses. Worse, there are also mischaracterized diesel horsepower as a kilowatt to the user, and use a diesel engine that is less than the generator power to configure the unit, commonly known as: small marathon cart, so that the unit life is reduced, maintenance is frequent, the use of fees Highly high.

7, do not talk about diesel engine and generator brand grade, control system configuration, talk about after-sales service, blindly talk about price and delivery time. Some will also use non-power station-specific oil machines, such as marine diesel engines and automotive diesel engines for generator sets. So that the end product of the unit - the quality of electricity (voltage and frequency) can not be guaranteed.

8, do not talk about random accessories, such as with no silencer, fuel tank, pipeline, with what grade battery, how much battery, a few batteries and so on. In fact, these attachments are very important and must be stated in the contract. What's more, even the water tank fan is not included, allowing the customer to open the pool.

In combination with the above, you must be cautious when purchasing a diesel generator set. Ask the manufacturer when buying.
