Ex Factory Price Cummins Water Cooled Three-Phase 250kva Diesel Generator

product presentation:

Diesel generator is a kind of small power generation equipment, refers to the diesel fuel, diesel engine as the prime mover to drive the generator power machinery. The whole set is generally composed of diesel engine, generator, control box, fuel tank, starting and control storage battery, protection device, emergency cabinet and other components.

Diesel engine cylinder head and cylinder body are cast in the cooling water jacket. After the coolant is pressurized by the water pump, it enters the cylinder water jacket through the water distribution pipe. The coolant absorbs the heat of the cylinder wall while flowing, and the temperature rises. Then it flows into the cylinder head water jacket and enters the water pipe into the radiator through the thermostat and the radiator. The heat of the cooling liquid flowing through the radiator core continues to disperse into the atmosphere, reducing the temperature. Finally, it is pressurized by the water pump and then flows into the cylinder water jacket again, so the continuous cycle, the diesel engine speed rises. In order to make the multi-cylinder diesel engine before and after each cylinder cooling uniform, the general diesel engine in the cylinder body water heavy set water distribution pipe or cast water distribution chamber. The water distribution pipe is a metal pipe, along the longitudinal thermal outlet hole, the larger the water pump, so that the cooling intensity of the cylinder before and after is similar, the whole machine cooling evenly.

The water cooling system is also provided with a water temperature sensor and a water temperature meter. The water temperature sensor is installed at the outlet pipe of the cylinder cover, and the water temperature of the outlet pipe is transferred to the water temperature meter. The operating personnel can understand the working condition of the cooling system at any time with the help of the water temperature table. The normal working water temperature is generally 80-90℃. Coolant and anti-cold liquid, the coolant used by diesel engine should be clean soft water, if the use of hard water, which minerals at high temperature sink out, attached to the pipe, water jacket and radiator core to generate scale, reduce the heat dissipation capacity, easy to make the diesel engine overheating, radiator core poisoning, accelerate the wear of the pump impeller and pump shell. For hard water with more minerals, it needs to be softened before it can be added to the cooling system. The commonly used method of hard water softening is to add sodium carbonate 0.5-1.5g in 1L water, or add sodium hydroxide 0.5-0.8g. After the impurities are precipitate, clean water above is injected into the cooling system.
