Definitions

  • the invention relates to a device for filtration and simultaneous air separation of water circuits, especially on pumps.
  • Water in heating or sanitary facilities is often through Rust, solder residues, lime abrasive substances etc. moved or dirty. If it is not filtered, it can it in the system in heat exchangers, pumps, valves etc. damage.
  • the object of the invention is a replaceable Creating device operating in a water cycle, especially in the return of a pump housing can be integrated.
  • the device is used on the one hand to filter the Water before it through the downstream components, such as Pump motor, heat exchanger, valves etc. one Boiler etc. flows. Second, through this Device separates the air from the water, then through the automatic bleeder integrated in the pump to be eliminated. It has been shown that a small ventilation space compared to known ones Vent pumps is sufficient.
  • the Vent chamber is disc-shaped and a level to Back has parallel front.
  • you can the front is (partially) spherical.
  • the level in particular Filter as a filter disk parallel to the rear, in particular between the front and back, detachable is attached.
  • the filter disc can outer, in particular at least partially circular Have frames.
  • the filter can be easily replaced if the filter frame by locking means in the Vent chamber is releasably attached.
  • the device has a housing 11 with a curved, in particular partially spherical or flat Front 12 and a back 13 parallel to it. There is one between the front and back Vent chamber 5. With the flat back 13 is the Device on a flat connection surface of a pump attachable, which has a suction and pressure opening. In there is an inlet opening 14 on the flat rear side and an outlet opening 15 which is connected to the pressure opening and the suction opening of the pump or hydraulic system are connected.
  • the device has a fine-mesh filter 3, the optionally surrounded by a frame 4. Of the Frame stiffens, especially when choosing an unstable Filter material the filter.
  • This filter unit will inserted into the chamber 5 of the connection adapter 1 in such a way that the suctioned water first flows through the filter must before it gets into the spiral space of the pump. As a result, the water is filtered.
  • the filter unit also forms the partition between an unfiltered suction side Vent chamber 5 and a vented, filtered Area 6 of the connection adapter 1. This vented, the filtered area can, if necessary, directly Form spiral space or be in front of it.
  • the mesh size of the filter must be designed in this way be that the air to be separated by the Filters of the water to be transported to a high degree be separated. It is also important to ensure that the Filter does not become dirty too quickly.
  • a material can including a braid made of stainless steel or a plastic filter can be used. Since it's in the course the filter will become dirty during the period of use can, there is an opening 7 in at a suitable location this provided by the closed filter the water can flow into the spiral space of the pump.
  • the Position of the opening is determined by the arrangement of Suction nozzle 8, and automatic vent 9 and through the Inner contour of the connection adapter 10 or pump housing dependent.
  • the attachment of the filter unit should be releasable Snappers 17, press fits etc. are carried out to to achieve a quick exchange and assembly.
  • the position and shape of the unit is determined by the Design and the nozzle arrangement of the housing certainly.
  • the automatic vent 9 works as follows:
  • the air or air bubbles to be discharged are due to their buoyancy from a pipeline or a Vent chamber in the housing of the quick breather.
  • This housing is covered by the cover of the Quick exhaust valve tightly closed.
  • On the lid is the entire ventilation mechanism is installed.
  • the air can flow between the piston and the O-ring escape until the float rises through the Water level the piston back to the lever Has pressed the O-ring.
