Introduction: Many users are blind when buying a generator set. They do not know how to distinguish between good and bad. Let's take a look at the eight traps that should be watched when choosing a generator set.
1. 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.
2. Do not talk about the relationship between the long-line (rated) power and the backup power. Only one “power†is mentioned. The backup power is sold to the customer 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.
3, 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.
4, the two mobile phone refurbished as a new machine to sell to customers, and some will refurbished diesel engine with a new generator and control cabinet, so that ordinary non-professional users can not tell whether it is a new machine or an old machine.
5, 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, British Stanford. In fact, any diesel generator set cannot be completed by a single company. The customer should 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.
6. Units that do not have protective functions (commonly known as four-protection) 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.
7. Do not talk about the diesel engine and generator brand grade, control system configuration, do not 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. Units with too low prices generally have problems, commonly known as: Only bought the wrong is not sold wrong!
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.
Diesel generator sets are important standby power supply equipment. Care must be taken when purchasing them. When using them, they are handy. Therefore, when purchasing a generator set, you should select the authentic generator manufacturer, and make a decision on the site visit!
