Beware of the eight purchase traps of diesel generators
- Aug 22, 2017 -

Diesel generating units as an emergency backup power, because of its reliability, timeliness and security, more and more users to accept and use. However, the purchase of a suitable diesel generator is not a very easy thing. Wagger Electricity Technology Company to remind users to buy generators to guard against the following eight traps.

 

    1.Only reported that the diesel engine or generator brand, do not report the origin, not reported unit brand. In fact, any diesel generator set can not be completed by an independent business. Customers should fully understand the unit of diesel engines, generators, control cabinet manufacturers and brands, in order to comprehensively assess the quality of the unit.

  

   2.Do not speak the relationship between rated power and standby power, only say a "power", the standby power as the rated power sold to customers. In fact, the standby power = 1.1x rated power. Moreover, the standby power can only be used for 12 hours in continuous operation for 1 hour.


     3.Confuse the relationship between KVA and KW. KVA as KW exaggerated power, sold to customers. In fact KVA is apparent power, KW is the effective power, the relationship between them is 1KVA = 0.8KW. Import units generally use KVA that power units, and domestic electrical equipment are generally used KW said, so the accounting power should be KVA 8 fold converted into KW.

   

     4.Sale second-hand machine as a new machine to customers, there will be refurbished diesel engine coupled with a new generator and control cabinet, so that the general non-professional users simply can not tell whether it is a new machine or old machine.

   

     5.Will not protect the unit as a protective function of the unit sold to customers. What is more, the instrument will be incomplete, without air switch generator to sell to customers. In fact, the industry generally provides more than 10KW units must bring the whole instrument and air switch; large units and automation units must be with four protection functions.

The same time as

   

     6.Do not talk about random accessories, such as with no silencer, fuel tank, oil pipeline, with what grade battery, how much capacity battery, a few batteries and so on. In fact, these attachments are important and must be stated in the contract. What is even the water tank fans are not brought, so that customers from the open pool.

   

  7.The diesel engine power and the power of the generator configuration as large, in order to reduce costs. In fact, the industry generally provides diesel power ≥ 10% of the generator power, because there are mechanical losses. More harsh, and the diesel engine horsepower as a kilowatted false alarm to the user, and with less than the generator power of the diesel engine to configure the unit, commonly known as: small horse carts, as well as unit life, maintenance, High.

 

  8.Talk about the diesel engine and generator brand grade, control system configuration, talk about after-sales service, blindly talk about the price and delivery time. Some will also be non-power plant special oil, such as: marine diesel engine, vehicle diesel engine for generating units. So that diesel generator sets of end products? The quality of the electricity (voltage and frequency) can not be guaranteed. Too low price of the unit is generally a problem.
