- second flange 175, which is attached to the valve housing 151 is connected to the first flange 171 on the outlet pipe 113 is attached.
- the pump housing 110 has a variety of flat ones Projections 118 (see Figures 5 and 10). If the pump housing 110 faces down, the flat ones are Protrusions 118 in contact with the ground and wear the pump housing 110.
- valve 153 closes by its own Weight has moved down, as by the solid line in Fig. 6, the interior of the valve housing 151. From this state on after opening a tap (or valve) the consumer in the fluid in the valve housing 151, connected to the consumer side through which Tap drained while turning the valve 153 due to a difference between the pressure in the Inlet pipe 111 and the pressure in the valve housing 151 next to the consumer side along the guide rod 157 moved up. As in the broken line in Fig. 6, thereupon the interior of the valve housing 151 opened while the Reed switch 167 through the one on the top of the valve 153 arranged magnet 155 is turned on and sends an operating signal to the control unit 140. The control unit 140 then actuates the motor 130, which rotates the impeller 120 and thereby draws in the fluid and ejects.
- the inventive automatic pump not just the valve assembly releasably connected to the pump housing, but there may also be an angular position of the valve assembly can be set so that the automatic pump is independent of the direction can be installed.
- the reed switch is attached to the pad by connecting both ends of the reed switch with the Conductor patterns are welded to the base, after a middle section of the reed switch in the empty space was arranged in a middle Section of the pad is formed. So that's it manual work of attaching the reed switch the pad simple and easy.
