Eight major traps to pay attention to when purchasing diesel engines

When purchasing a diesel generator set, the editor reminds customers to be careful. 1. Confusing the relationship between KVA and KW. Use KVA to exaggerate power as KW and sell it to customers. In fact, KVA is apparent power, KW is power, and the relationship between them is IKVA=0.8KW. Imported units are generally represented by KVA, while domestic electrical equipment is generally represented by KW, so when calculating power, KVA should be converted to KW at a 20% discount. 2. Do not talk about the relationship between long-line (rated) power and backup power, just talk about one 'power' and sell the backup power to customers as long-line power. In fact, backup power = 1.1x long-row power. Moreover, the backup power can only be used for 1 hour during continuous operation for 12 hours. 3. The power of the diesel engine is configured as large as that of the generator to reduce costs. In fact, the industry generally stipulates that the power of diesel engines is ≥ 10% of the generator power because of mechanical losses. Even worse, some people use diesel engine horsepower as a kilowatt false alarm to users, and use diesel engines with less than the generator power to configure the unit, commonly known as: a small horse pulls a big cart, and even the unit life is reduced, maintenance is frequent, and the usage fee remains high. 4. Sell the second-hand refurbished machine to customers as a brand new machine, and some also match the refurbished diesel engine with a brand new diesel generator set and control cabinet, making it impossible for ordinary non-professional users to tell whether it is a new machine or an old machine. 5. Only report the diesel engine or generator brand, not the place of origin, not the unit brand. Such as Cummins, Sweden Volvo, and Stanford, UK. In fact, no diesel generator set can be completed independently by one company. Customers should fully understand the manufacturer and brand of diesel engines, generators, and control cabinets of the unit before they can comprehensively evaluate the grade of the unit. 6. Sell units without protection functions (commonly known as four protections) to customers as units with complete protection functions. What's more, the incomplete instrumentation and no air switch are sold to customers. In fact, the industry generally stipulates that units above 10KW must have full instruments (commonly known as five meters) and air switches; large units and automated units must have self-four protection functions. 7. We do not talk about the brand grade and control system configuration of diesel engines and generators, nor do we talk about after-sales service, but only talk about the price and delivery time. Some also use non-power station oil engines, such as marine diesel engines and automotive diesel engines for generator sets. The quality (voltage and frequency) of the unit's terminal product cannot be guaranteed. Units with too low prices generally have problems, commonly known as: only if you buy the wrong one, you don’t sell the wrong one! 8. Don’t talk about random accessories, such as whether to bring a silencer, fuel tank, oil pipe, what grade of battery, how large the capacity battery, how many batteries, etc. In fact, these attachments are very important and must be stated in the contract. What's more, there are not even a water tank fan, allowing customers to build their own open pool.
