Cautions on Common Sales Traps When Purchasing Diesel Generator set

Purchasing diesel generator sets is a great learning. First of all, it depends on the generator brand and manufacturing process. During the test, whether or not the voltage of the generator is stable, the pressure builts fast, the frequency is table, the vibration is large, the size and color of the engine exhaust is normal, the exhaust gas is big and there are other noises, etc. Secondly, users should also be familiar with the following eight common traps in purchasing diesel generator sets.

1. Confusing the relationship between KVA and KW. Treat KVA as KW exaggerated power and sell it to customers. In fact, KVA is the apparent power, and KW is the effective power. 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 with a 20% discount.

2. Don't talk about the relationship between long-term (rated) power and reserve power, just talk about a "power", and sell the reserve power to customers as long-term power. In fact, reserve power = 1.1x long-travel power. Moreover, the backup power can only be used for 1 hour during 12 hours of continuous operation.

3. The power of the diesel engine is the same as the power of the generator, in order to reduce the cost. In fact, the industry generally stipulates that diesel engine power ≥ 10% of generator power because of mechanical loss. Worse still, some people misreport the horsepower of the diesel engine as kilowatts to the user, and use a diesel engine less than the generator power to configure the unit, commonly known as: small horse-drawn cart, and even the life of the unit is reduced, maintenance is frequent, and the use cost is high. High.

4. Sell the refurbished second mobile phone as a brand-new machine to customers, and some refurbished diesel engines are equipped with brand-new diesel generators and control cabinets, so that ordinary non-professional users cannot tell whether they are new or old.

5. Only the diesel engine or generator brand will be reported, not the place of origin, nor the unit brand. Such as Cummins in the United States, Volvo in Sweden, and Stanford in the United Kingdom. In fact, it is impossible for a single company to complete any diesel generator set independently. Customers should fully understand the manufacturer and brand of the diesel engine, generator, and control cabinet of the unit in order to comprehensively evaluate the grade of the unit.

6. Sell the unit without protection function (commonly known as four protection) as a unit with complete protection function to customers. What's more, the unit with incomplete instrumentation and no air switch will be sold to customers. In fact, the industry generally stipulates that units above 10KW must be equipped with full meters (commonly known as five meters) and air switches; large-scale units and automatic units must have self-four protection functions.

7. Don't talk about the brand grades of diesel engines and generators, control system configuration, and after-sales service, just talk about price and delivery time. Some also use non-power station special oil engines, such as marine diesel engines and automotive diesel engines for generating sets. The terminal product of the unit-the quality of electricity (voltage and frequency) cannot be guaranteed.

8. Don't talk about the random accessories, such as with or without silencer, fuel tank, oil pipeline, what grade battery, how large capacity battery, how many batteries, etc. In fact, these attachments are very important and must be stated in the contract.
