FAQ

 What are the main parts of a generator set?

A diesel generator set consists of a diesel engine, an alternator and various ancillary devices such as chasis, control systems, circuit breakers, canopy. A diesel generator set is some time called a genset for short.

 
What is important in selecting a generator set?
Diesel generator sets are selected by the load they are intended to supply power to. When selecting a diesel generator set you need to take into account the type of load, if it for emergency of continuous power, and the size of the load, and size of any motors to be started which is normally the critical parameter.
 
Where does the generator set used and the respectively power range?

Diesel generating sets are used as backup emergency power if the main power fails. They are also used in areas where electricity is not available such as construction sites or remote locations. We have generator set range from 8kVA to 3000kVA in output power and they can be used for homes, offices, hospitals, shopping mall, municipal construction, place of entertainment, etc..

 

What type of generator set do I need?

The type of generator that you need will vary depending on what it is required to power, where it will be installed and whether it is needed to run continuously or only when there is a power outage.

YANAN offers generator sets to provide prime power, standby power and continuous power. We produce diesel units as small as 8 kVA that are ideal for domestic and small retail properties up to sets as large as 3,000 kVA that can provide power for complete villages and even feed back into national electricity supply grids. Our generator set can be started either manually or automatically and can be provided as open sets, soundproof type and containerised sets. There is also the option to have the generator mounted on a trailer if it needs to be transportable.

To establish what type of generator is most suitable for you, contact our technical department who will be able to size and quote for your requirements.

 

What do I need to know about engine room?

To run a generator set effectively, it is strictly required in correctly assembling the generator set. Make sure the layout of engine room is reasonable for problem free maintenance. Meantime, the engine room should comply with the local building code and fire code announced by local government or other relevant regulations.

You must ensure that:

-Protect the diesel generator set from rain, sun, wind, etc.;

-Keep a good ventilation in engine room, which should be large enough. 

-Exhaust the hot air out of the engine room to reduce the influence caused by the room temperature increase;

Silencer and exhaust pipe should be clamed by suspension system to ceiling, which is designed to support the silencer; It is forbidden to install the exhaust system on top of generator set directly.

 
What do I need to know about anti-vibration?

The diesel generator set (except some models) is supported on inbuilt rubber mounts and not normally require another special measure to isolate vibration and you can refer to the installation guide to right install the set in level and smooth slab with expansion bolts.

The flexible connection should be fitted between the components in generator set and outside parts, such as: an exhaust expansion should be fitted on the engine outlet; exhaust duct, oil inlet tube, oil outlet tube and electric cables should be with flexible connections to insulate the most vibration. 

 
What happens if I overload a generator?
Generator sets should not be overloaded once running, but are designed to take an overload condition for a very short time during start up of the set. If a set is running for long periods of time with an overload condition (that is a rating above the maximum rating of the set) various things may occur.
These include such things as :
Overheating of the coolant system
Overheating of the alternator windings
Oil viscosity (thickness) break down resulting in low oil pressure
A shortening of the working life of the generator
  
What happens if I underload a generator?

All engines are designed to operate under varying load, ranging from the maximum down to the minimum. Problems occur when light loading (min load) is sustained for long periods of time resulting in the engine not getting up to its normal temperature. Oil in the cylinder that is normally burnt is heated and a lacquer is formed on the cylinder liner. If the light loading continues, visible blue smoke will appear and the engine will require service work to deglaze the liner or replace it. 

  
What should I pay attention in assembling the exhaust system?

The diesel generator set with standard configuration, such as industrial silencer, flexible exhaust connection and elbows. The user can assemble the exhaust system with the offered matching facilities, but must pay attention to the below points as well.

1. Make sure that the back pressure is lower than the maximum setting value (Usually, the back pressure is lower than 5kpa.)

2. Fix the exhaust system to avoid the longitudinal pressure and lateral.

3. Reserve the room for contraction and expansion. 

4. Reserve the room for vibration.

5. Reduce the exhausting noise.

 
What will happen in high back pressure?

The excessive back pressure will cause the below

1. Power loss

2. Fuel economy deterioration

3. Exhaust temperature rising
