Aerator (aerator) brand - Hing Kong aeration, Hing Kong environmental Xi'an branch of "De-oriented, business integrity, mutual win-win" principle struggled for years, since the establishment of access to the majority of users acclaim. We sincerely welcome all walks of life to cooperate with us. Contact 0311 -85,236,167. Hu: 13831199587. Aeration hose variable orifice basic principle is: 1, the use of the "internal pressure of the pressure vessel the principle of equal everywhere," as used in refineries Jiujiang Each hose is up to 60 meters and gas distribution remains homogeneous. (As entered on the hose aeration gas filling the hose when the park, the aeration resistance under the action of time and no vent hose, the hose is equivalent to the pressure vessel internal pressure is equal everywhere. Proceed Intake When aeration overcome resistance to uniform outlet hose do 2, variable orifice openings aeration hose way slit type, the outlet flow rate under the action of a variable cell size, volume adjustment range large, relative to other needle-type (hole size changes very little volume adjustment range is small) of aeration, its outlet resistance is not large. That is when it reaches a certain volume, the other a total micropore aerator The outlet resistance is quite large, while the total variable orifice aeration hose outlet resistance is not so big.
