1、 Why do I need a backup power supply?

In today's world, the most important thing is to be fully prepared for anything. For people who have experienced power outages, power outages have a great impact on their daily life and work. Power supply is the most important basic energy in the development of national economy, which is related to the national economy and the people's livelihood. On many occasions, such as hospitals, banks, airports, railways, important conference centers, daily office places and other important places, as well as the fire protection and security systems of general buildings, these have high requirements for the continuity of power supply. In addition to providing necessary standby power supply, these places also need to set up uninterruptible power supply system.

2、 Diesel generator set is a common standby power supply

As long as the supply of diesel can be guaranteed, it can supply reliable electric energy for a long time. It can be completed in places where the power supply of power grid cannot be guaranteed, whether in field operation, disaster relief and other occasions. This is the advantage of diesel generator. Similarly, its disadvantages are:

1) The generator set has a long start-up time, which can not meet the needs of power conversion time of some equipment.

2) The operation of the generator requires sufficient oxygen and serious fuel gas pollution.

For the construction of generators, air inlet, exhaust, smoke exhaust channel and smoke removal equipment need to be considered. In areas with strong environmental awareness, it is also required that the smoke exhaust outlet must be at the highest place in the downwind direction of the building complex, which brings some trouble to the architectural design;

3) The noise and vibration generated during generator operation pollute the environment, and the use of rooms around the generator room is limited;

3、 Black smoke control scheme of diesel generator

Our black smoke control device is customized according to the timely needs of customers to control the black smoke of diesel engine exhaust with various displacement. It can match the diesel engines of mainstream brands at home and abroad, including Cummins, caterpillar cat, platinum Perkins, antyou MTU, Volvo, Mitsubishi (Mitsubishi Heavy), Shantou Doosan, Weichai, cork googol, Yuchai, Weiman VMaN, Shangchai, jichai, tongchai, Wudong, etc. Reasonable selection shall be carried out in combination with different engine exhaust volume and air cooling, and the most satisfactory treatment effect shall be achieved based on the actual situation. When the tail gas purifier works, the shell surface temperature can reach 300-400 ℃, so it is required to keep a certain space distance between the purifier and other components, especially the fire-fighting facilities in the generator room. When the fire detection rod is above 75 degrees, it will give an alarm and turn on the sprinkler head at the same time, so the exhaust gas purifier installed indoors needs to be insulated outside the shell. When the temperature of the exhaust port reaches 200-300 ℃, keep it away from the pedestrian aisle to avoid high-temperature gas damaging the human body. When the internal back pressure of the black smoke purifier rises to the maximum allowable back pressure due to the accumulation of particles, the electronic control system will automatically send an audible and visual alarm, and the high temperature resistant solenoid valve will automatically open the bypass to ensure the safe operation of the diesel engine.
