Definitions
- the invention relates to a centrifugal pump with a a housing arranged interchangeable insert, the has an inlet and an outlet which in one side flat and open side wall of the housing lie, and with a top on the outer edge of the housing (3) attached ventilation device (9), below which the Insert (13) is arranged.
- Pumps are known to change their design
- Direction of rotation or by actuating internal pumps can alternately supply different circuits.
- the valves are either hydraulic or mechanically operated.
- a centrifugal pump is known from DE 36 24 917, which is a housing with a side flat and open Has side wall in which an insert can be replaced can be introduced.
- DE 36 24 917 is a housing with a side flat and open Has side wall in which an insert can be replaced can be introduced.
- pressure-side and suction-side channels individually, so that it is possible with such a pump, for example is, they with two suction and a pressure nozzle or to operate in reverse. So this pump is too Suitable for supplying several circuits.
- the ventilation system at the highest points in the heating system be provided where the air is removed from time to time can be. Because this type of venting is unfriendly to maintenance, it is known in the pump Vent valves, so-called quick breather integrate. These quick exhaust ventilate the air during operation of the pump continuously to the environment.
- DE-U-94 16 551 for example, includes a pump known such a vent.
- FR 1 532 578 shows one pump with another Embodiment of a breather.
- the object of the invention is to provide a centrifugal pump create through an interchangeable insert for Supply of multiple circuits can be used and which is also the venting of each circuit ensures.
- This task is characterized by the characteristics of the Claim 1 solved.
- the advantage of such a pump is that the pump is universal can be adapted to the needs of the user without the ventilation device must be replaced. Here can use this pump to operate multiple system circuits simultaneously be vented. The ventilation takes place automatically, without the user or a heating installer System must wait. This means effort and costs lowered.
- the centrifugal pump according to the invention is in a special one Embodiment designed to be in two Direction of rotation can be operated and so two can supply independent circuits. Therefore, it can be simply replace it with an existing double pump.
- the centrifugal pump 1 is operated by an electric motor 2, the direction of rotation in a special embodiment is reversible.
- the electric motor is on the outer housing 3 attached and operates an impeller 5 via a shaft.
- the electric motor is advantageously a canned motor.
- the housing 3 has a flange 4 sealed against the heating system.
- the design of the pump is flange 4 with an outlet 7 and provided with an inlet 8.
- Inlet 8 and outlet 7 are located on a side flat and open side wall 10 of the housing 3.
- the suction side of the pump 1 is by means of a venting device 9 vented on the top Outside edge of the housing 3 is attached.
- FIG. 2 shows two sections through the pump 1 described.
- Section A-A shows the venting device 9 which is mounted on top of the housing 3.
- the Venting device 9 has a float 11, the one Valve 12 actuated, through which the existing air escape can.
- the housing 3 there is an insert 13 which in the special embodiment is in two parts. One part is formed by the flange 4, which in the housing is sufficient and in the area of the ventilation device 9 Has passage openings 14. Through these openings 14 the water at the venting device 9 passed by, so that the air can collect. At a special embodiment, the ventilation either on the pressure side or on the suction side.
- a second part 15 of the insert 13 In addition to the flange 4 is a second part 15 of the insert 13 arranged.
- This hydraulic insert 15 points in this embodiment has a spiral channel, through which the impeller 5 the water to the pressure side promoted.
- the hydraulic insert 15 is interchangeable in introduced the housing 3.
- the flange 4 is on the inside reinforced with ribs 16.
- the section B-B shows the impeller 5 on the suction side Water is supplied and this through the hydraulic use 15 defined channels on the Pressure port 8 promoted.
- the venting device is designed so that it in each case at least one channel through which pressure or Vented on the suction side.
- FIG. 3 shows a pump 1 with the described Housing 3 and the electric motor 2.
- the hydraulic use 15 and the flange 4 are designed so that the pump two Inlets 7 (suction ports) and one outlet 8 (pressure ports) having.
- a valve 17 closes either one or the other inlet 7.
- the valve 17 has a seal 18 on and is pivotally mounted on an axis 19.
- the Venting device 9 ventilates both suction sides the pump.
- Inserts 13 are used in the pump housing 3 . If the direction of rotation of the The motor 15 is reversible (reversing pump), the insert 15 a valve on which switches between two Channels. So the pump with two suction and a pressure port or vice versa. The Venting of the channel through which the flow is flowing is carried out by the Venting device ensured.
- any use is conceivable that for example the water in several different Promote channels at the same time.
- the ventilation can again on each channel flowed through.
