Now the market diesel generator set can be said to be good and bad intermingled, and some friends in order to save money, always where cheap where to buy, little do not know, if the diesel generator set is not very familiar, the best generator manufacturers with the purchase of professionals, the police to be deceived.

1. Just say a "power", not to mention the rated power of the diesel generator set or the connection between the backup power. If you sell the backup power as the rated power, you should know that the backup power can only run for one hour within 12 hours before purchasing, and the backup power is about 1.1 times of the rated power.

2. Demand to understand, KVA is the apparent power, kW is useful power, KVA power is equal to 0.8 times of kW power, so when purchasing diesel motor set, KVA power must be converted into kW power.

3. If the second-hand innovative diesel generator set is sold to a customer as a brand-new generator set, or some parts in the diesel generator set are used as second-hand ones, some users who do not know the diesel generator set can not tell whether they are innovative machines or not, and finally they are cheated.

4. In order to reduce the cost, some businesses allocate the power of the diesel engine and the power of the generator to the same size. According to the working regulations, in order to reduce the mechanical loss, the power of the diesel engine should be at least 10% higher than that of the generator before it is qualified. Otherwise, the failure rate of the diesel generator will be improved and its life will be shortened.

5. We have been talking with customers about the price, not about the standard parameters, brand and after-sales service of diesel generator sets. Generally, diesel generator sets with too low price have problems, and they are not cheap if they are cheap.
