Pitfalls to Be Aware of When Buying Cummins Generator Sets

Today we will briefly introduce the pitfalls that users should pay attention to when purchasing Cummins generator sets.

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, so when calculating the power, KVA should be converted into KW with a 20% discount.

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

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 configure the unit with a diesel engine less than the power of the generator, commonly known as a small horse-drawn cart, so that the service life of the unit is reduced, maintenance is frequent, and the use cost is high. High. Selling refurbished second-hand phones to customers as brand-new ones, and some refurbished diesel engines with brand-new generators and control cabinets, making it difficult for ordinary non-professional users to distinguish whether it is a new one or an old one.

Only the diesel engine or generator brand is reported, not the place of origin, nor the unit brand. Such as USA Cummins, Sweden volvo, British Stanford. In fact, no Cummins generator set can be completed independently by a single company. 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.

The unit without protection function (commonly known as four protection) is sold to the customer as a unit with complete protection functions. 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.

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. So that the terminal product of the unit-the quality of electricity (voltage and frequency) cannot be guaranteed. Cummins generator sets that are too low in price generally have problems, commonly known as: There is nothing wrong with buying a wrong one!

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. What's more, even the water tank fan is not included, allowing customers to open the pool by themselves. Cummins generator set is an important backup power equipment, so you need to be cautious when purchasing it, so that it can be handy when you use it.

Dingbo Power was founded in 2006 and is one of the earliest manufacturers of generators and diesel generator sets in China. If you want get more information, please feel free to send email to sales@dieselgeneratortech.com we will pay highly attention on your question.
