In the festive seasons and on the special occasions of our life we love to crack fireworks. Some people love to go for the one that produces sound and some love to see the light and different images that produce in the sky during night. First of all the chemical reaction of the objects and raw materials is very important. This is the base of any firework. This is called pyrotechnics. This ensures that the raw material go for an exothermic chemical reaction and thus produces light, smoke, heat and sound. Some crackers come with excessive sound as well! Find your machine on internetÂ
The third reason is they people often feel lonely and isolated. Although people's social circle has been enlarged through the advanced social life methods and frequent flow from the population, the both depth and length in the affection have been reduce by a large degree. People have dwindling faithful and sincere friends.
The filter adopts high - strength wedge-shaped strainer to control the automatic cleaning of filter element through pressure differential control. When the impurity accumulates in the filter surface causes the import and export pressure difference to increase to the set value, or the timer reaches the preset time, the electric control box sends out the signal to drive the anti-flushing mechanism. When backwash suction dish and filter imports are pair, the drain valve is opened, the system pressure drainage, chuck and filter the inside a relative pressure below the filter of the lateral pressure of negative pressure zone, forcing some net circulating water from the inside filter lateral flow filter, adsorption on the inner wall of the filter in the impurity particles with flow into ç©£ disc and is discharged from the drain valve. The specially designed filter causes the inside of the filter to produce a jet effect, and any impurities will be washed away from the smooth inner wall. When the pressure difference of the filter is returned to normal or the timer set time is finished, the material does not break the flow during the whole process, and the anti-washing water consumption is low, which realizes the continuous and automatic production
