Avoid buying the eight myth of diesel generators

How to avoid buying the eight myth of the diesel generator?

A.Confuse KVA relationship with KW diesel generator. Sell KVA as KW to exaggerate the power, to the customer. In fact KVA is apparent power, KW is the effective power, the relationship between them is IKVA = 0.8 KW. Import units generally expressed in KVA power unit, and domestic electricity equipment is generally expressed in KW, so accounting power should be the KVA 8 discount when converted to KW.

B.Don't speak prime power and backup power relations, said only a "power", the backup power as a prime power sold to customers. In fact, the backup power = 1.1 x prime power. Moreover, backup power can only use 1 hour in 12 hours continuous running.

C.Diesel engine power is as large as the generator power is configured to, in order to reduce the cost. In fact, the general provisions of diesel engine power generator power 10% or higher, because there are mechanical wear and tear .

D.Sell used a refurbished machine as a new machine to the customer, and will be renovated with new diesel engine generator and control cabinet, make general non-specialist user root can't distinguish whether new or old machine 

E.The diesel engine or generator brand only, do not quote origin, not the brand unit. Such as the United States cummins, Volvo of Sweden, Britain Stanford. In fact any a diesel generating set impossible by a company independently. Customers should be a comprehensive understanding of the unit of diesel engine, generator, control cabinet manufacturers and brands, to comprehensive assessment of the level of the unit. 

F.Will not take protection function unit as a fully functional units sold to customers. What's more, the instrument is not complete, with no air switch unit sales to the customer. 

G.Don't talk about brand grade of the diesel engine and generator, control system configuration, don't talk about after-sales service, only talk about the price and delivery time 

H.Don't talk about random accessories, such as with or without silencers, oil tank, oil pipe, with what the grade of battery, how much capacity battery, battery and so on. In fact, it is very important to these attachments, must be stated in the contract. What is more even without a radiator fan, let the customer since the open pool. 

The choice of standby diesel generator set .What is a standby generator set .

In daily life have a standby diesel generator set is very important.Backup diesel generators can continue to provide energy for you, when the power to prevent accident is difficult to pick up .No matter how much you daily power consumption of the products of our company can provide backup power for you.Our company the power of the diesel generator from 10 kw to 500 kw.If not meet your demand of the diesel generator we can made for you.

1.What is a standby generator set ?

Normally required power from the mains supply, the user when the mains electricity switch or other reasons, the interruption of power supply, to ensure that the user's basic production and living of generating set. This kind of generating set standing in the telecom sector, hospitals, mains supply tension, such as industrial and mining enterprises, airports and television important unit of electricity. This type of unit to keep standby mode at any time, can provide a continuous power supply for unsteady load.

2.The choice of standby generating sets.

Coefficient of load capacity, the sum is multiplied need after the calculation of load is less than the capacity of the emergency diesel generator set, spare coefficient according to 1.2, or 1.2 times the calculated capacity is less than the capacity of the emergency diesel generator set, after the mains power outage, power supply from the emergency generator to the load. Load capacity, the sum is multiplied need coefficient after the calculation of the capacity of the load is greater than the single emergency diesel generator set, can choose two types, capacity, voltage regulator, same speed similar features automatic generating set. After the mains power failure, by one or two units to the life and commercial electricity power supply; When mains power failure, fires, by 2 units to power supply, fire load and fire fighting.

Second I want to and you say some common problems about the diesel generator set.

1.Generating set in a period of time and found the rest everything is ok but the main reason for decline in power .

  a.Air filter is too dirty, inhaled air is not enough, then must clean or replace air filters.

  b.Fuel filter was too dirty, fuel injection quantity is not enough, must be replaced or cleaned.

  c.Ignition timing is not straight, and must be adjusted.

2.Diesel generator set in use must pay attention to what is essential in time.

  a.The water in the tank must be sufficient, and keep working in the allowed temperature range.

  b.Lubricating oil must be in place, but not too much, and keep the pressure of allowing within the scope of work.

  c.Stable at around 50 hz frequency, voltage stability at about 400 v

  d.Three phase current within the rated range.

3.The main advantage of the brushless generator:

  a.Carbon brush of maintenance.

  b.radio interference resistance.

  c.Reduce the excitation-loss fault.

4.Have a generator set its voltage and frequency stability after loading, but where is the current instability problem.

  The problem is that the customer load is not stable, and the generator quality absolutely no problem

5.Diesel generator set which six basic equipment, including system

  a.The oil lubrication system

  b.The fuel system

  c.Control protection system

  d.Cooling heat dissipation system

  e.Exhaust system

  d.Starting system
6.Diesel generator should be noticed in winter

  a.Pay attention to the water tank must not be frozen, to prevent method by dedicated long-term rust, antifreeze, or use of electric heating equipment guarantee room temperature above freezing point

  b.It is forbidden to open fire to bake

  c.No-load preheating time slightly longer, before sending

7.Why phone use after a period of time need to change the engine oil and oil filter?

  In new period are the impurities into the oil pan, the oil and oil filter or chemical qualitative physical qualitative changes

8.Generator room must ensure that the clean, the ground has reason

  a.Diesel engine if inhaled dirty air can reduce power

  b.Impurities such as generator if the suction sand will make the insulation of the stator gap between damage, the person that weigh cause burning

If you have any more questions to ask, I'm very glad to answer for you!
