FAQS

• 1. Is the genset noisy?

  Every generator produces some amount of noise from the exhaust, the engine and the airflow. Huihe generators are designed to provide maximum noise control and are all noise level tested during production to ensure they meet relevant legislation. Huihe diesel generating sets of soundproof type have won the patent of invention, utility model and design, as well as the Certificate of Hi-Tech Products awarded by Jiangsu Technology Committee, which assures a high noise reduction performance of 85 db at 1 meter.

• 2. What are the standard components on a Huihe generator set?

  All generators are made up of a number of different parts. The following are the major components which are standard on all Huihe gensets:
  1. Engine
  2. Alternator
  3. Control Panel
  4. Air Filter
  5. Base Frame and Fuel Tank
  6. Circuit Breakers
  7. Guards
  8. Cooling System

  Optional parts can also be equiped onto a Huihe generating set to easily customize the product to meet the customer’s individual requirements.

• 3. How does a generator set work with the mains electricity supply?

  Constant mains electricity is supplied into premises via electrical cabling. When this mains electricity is disrupted due to power failures, a signal is sent from the transfer switch to the generating set which then starts up and sends generated electricity back into the premises. When the mains supply is restored the transfer switch blocks the power from the generating set and reverts back to the main supply.

• 4. What is Transfer Switch?

  Transfer Switch is a panel that is wired into the premises electrical distribution system to allow a generator to be used. It prevents the generator from back feeding into the mains power supply which could cause serious injury to line workers trying to restore utility power supplies.

• 5. How do I know which size of generator set to purchase for my premises?

  There is no correct answer to this question. The size of generator set required depends on a number of individual factors. To ensure that your generator set is correctly sized you should contact your local Huihe distributor. They will make an appointment to come out (visit) and help you identify the kVA or wattage rating for all the equipment and appliances on your premises that will be powered by a generator. This will then enable them to provide you with details of the exact size and type of generator that is most suitable for your needs.

• 6. 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

• 7. How long will a generator run on a tank of fuel?

  The amount of time that a generator will run on a tank of fuel depends on the size of the tank, the amount of time in which the generator is in use and the load that the generator has to fulfil. All Huihe gensets are designed to run for eight hours at their full rated load.

• 8. How long can a standby generator be continuously operated?

  There is no set answer to this question. Huihe generators are designed to last for long periods of time and function in heavy duty operations. However, it is important that the set is inspected regularly between each use, before restarting to check such things as fuel and oil levels and any signs of abnormalities. Our sets can run continuously when the amount of load is lowered.

• 9. Where can I get parts for my generator set?

  Once you buy or own a Huihe generator set, you will be able to purchase any spare parts you require from our local dealers in your area. Huihe's network of dealers stock a wide range of parts for our generator sets and should be able to provide you with the items you need.
