Please introduce the eight key points to pay attention to when purchasing Yuchai diesel generator sets

1, confuse the relationship between KVA and KW.Convert KVA to kW to exaggerate power and sell to customers.In fact, KVA is apparent power, KW is real power, and their relationship is IKVA=0.8KW.Imported units generally use KVA to represent the power unit, while domestic electrical equipment generally uses KW, so when calculating power, KVA should be discounted by 80% to convert to KW.

2, Do not discuss the relationship between long-line (rated) power and backup power, just say one 'power', and sell the backup power as long-line power to the customer.In fact, backup power = 1.1 times the long line power.And, the backup power can only be used for 1 hour in a continuous operation of 12 hours.

3, The power of the diesel engine is configured to be the same as the power of the generator in order to reduce costs.In fact, it is generally stipulated in the industry that diesel engine power ≥ 10% of generator power due to mechanical loss.Even worse, there are some who report the horsepower of diesel engines as kilowatts to users, and configure the system with diesel engines that are less powerful than the generator, commonly known as 'a small horse pulling a big cart', resulting in reduced system lifespan, frequent maintenance, and high operating costs.

4, Selling refurbished second-hand machines as new to customers, and some even install new generators and control panels on refurbished diesel engines, making it impossible for general non-professional users to tell whether it is a new or old machine.

5, only report the brand of diesel engine or generator, not the place of origin, not the brand of the unit.Like United States Cummins, Sweden Volvo, Britain Stanford.In fact, it is impossible for any diesel power generation unit to be independently completed by a single company.Customers should have a comprehensive understanding of the engine, generator, control cabinet manufacturer and brand of the unit in order to comprehensively evaluate the grade of the unit.

6, Selling units without protection function (also known as four protections) as if they have complete protection function to customers.Even worse, selling an aircraft crew without a complete instrument and without an air switch to customers.In fact, the industry generally stipulates that units with 10KW or more must be equipped with full instruments (also known as five tables) and air switches; large units and automated units must be equipped with self-protection functions.

7, Do not talk about the brand grades and control system configurations of diesel engines and generators, do not talk about after-sales service, but only talk about prices and delivery periods.Some will also use non-power station dedicated oil engines, such as marine diesel engines and vehicle diesel engines for power generation units.The terminal product of the machine cannot guarantee the quality of electricity (voltage and frequency).A unit with a very low price usually has problems, commonly known as: only wrong purchases, never wrong sales!

8, do not discuss random accessories, such as whether it has a silencer, fuel tank, fuel line, what grade of battery, how much capacity of the battery, how many batteries, etc.Actually, these attachments are very important and must be stated in the contract.Even more so, they don't even include the water tank fan, leaving the customer to deal with an open-air pool.

Yuchai diesel generator set is an important backup power supply equipment, and it needs to be purchased with great caution, only then can it be used with ease.
