The Red Baron, whose real name was Manfred Albrecht Freiherr von Richthofen, was the most famous German flying ace of World War I. He had a really short flying career, which spanned just over 50 % of World War I, and died with the age of 25 in April 1918 after being shot down over Morlancourt Ridge, at the Somme. He was officially credited with 80 air combat victories, though further report on data indicates that the number may have been better 100. As for Red Baron airplanes, all were Fokkers, or Albatroses, plus one Halberstadt D.II.
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
