Jet pump has two fluid feeds to be mixed for delivery where the jet tube has an axial adjustment against the mixer tube which can be set and varied while the pump is operating

摘要

The jet pump, to mix and impel at least two fluids (F1,F2), has a jet tube (2) which has an axial adjustment against the mixer tube (3). The axial setting of the jet tube (2) can be adjusted while the pump is operating. The adjustment range of the jet tube (2) is set so that the smallest cross section of the mixer tube (3) can open upstream and downstream. The tangential inlet tube (1) is at an angle to the center line (5) of the pump which is = 90 deg or = 60 deg and is -20 deg . The inlet tube (1) is connected to the pump housing at a tangent, with a spiral coil connection. The inner dia. (a) of the inlet tube (1) is 20-200 mm, and the inner dia. (b) of the jet tube (2) is 10-200 mm at its opening, and the inner dia. (c) of the mixer tube (3) at its narrowest point is 20-400 mm. The inner dia. of the mixer tube (3) increases gradually downstream from its narrowest point, along a tube length (d) of 50-3000 mm.
