Structural Requirements for Diesel Generator Sets 2

The previous article has already introduced the structural requirements of the diesel engine, fuel system, and lubricating oil system for diesel generator sets. In this article, the professional diesel generator manufacturer - Dingbo Electric will continue to introduce the structural requirements of the starting system, cooling system, intake system, heating system, noise and shock absorption system.

1. Start the system

1) The generator should be able to start and deliver electricity within 30 degrees after a power outage in the city. The starting system equipped with an engine should be able to start 6 times, with each start lasting 6 seconds and an interval of 6 seconds. Each generator set should be equipped with a starting system.

2) An automatic diesel engine starting device should be installed, and the success rate of starting should not be less than 99%. When the engine runs without load within the predetermined time, it should automatically stop. At the same time, the startup system should meet the manual startup requirements.

2. Cooling system

1) The engine of a diesel generator must be equipped with a closed cooling system with sufficient capacity. The air temperature rise of the radiator should be 15 ℃ or lower, but should not exceed 18 ℃ when fully loaded.

2) The guide pipe of the diesel generator set adopts flange connection.

3) Anti corrosion measures should be considered.

3. Air intake system

An effective air filtration system should be provided based on the working environment conditions of diesel generators.

4. Exhaust system

1) All heated surfaces of the exhaust system of diesel generator sets must be protected by heat or other shielding measures.

2) Stainless steel elastic connections and matching flanges should be installed under the fire suppressor.

3) Elastic exhaust expansion joints should be installed at the exhaust outlet. The generator set manufacturer should indicate in the bidding documents whether the exhaust temperature and emission indicators comply with national standards.

4) The facilities between the muffler and the exhaust port (including the muffler) on the sled are provided by the manufacturer, and the muffler fixing bracket and the exhaust system after the muffler are provided by the owner.

5. Heating system

The cooling water and lubricating oil heating facilities required for rapid start-up of emergency diesel generator sets should be equipped, and a circulation system suitable for engine antifreeze during shutdown should be set up.

6. Noise and shock absorption system

The main requirements are as follows:

1) The full load noise of diesel generator set is less than 105dBA (1m) and 75dBA (7m).

2) The diesel generator set should be equipped with good special shock absorbers to eliminate 98% of the vibration and toughen the transmission of the generator set. When the generator set is fully loaded, the maximum seismic amplitude should not exceed 0.5mm.

3) Rated capacity within the scope of supply (natural ventilation)

Dingbo Power was founded in 1974 and is one of the earliest manufacturers of generators and diesel generator sets in China. If you want get more information, please feel free to send email to sales@dieselgeneratortech.com we will pay highly attention on your question.
