Definitions
- the invention relates to a high-pressure fan to promote a gaseous medium in which in a tubular shell Fan wheel is arranged, of which the medium is essentially axial is sucked in, radially accelerated and blown out axially, and in which a fixed guide device is connected downstream of the impeller.
- blower is known (DE-A-38 42 697).
- Blower is a high pressure blower like it can be used for example for gas burners.
- blowers should have a steep pressure-volume characteristic, i.e. one The change in the static differential pressure is only slight Reduced volume flow.
- the well-known high pressure blower shows for most applications has a too complex structure, i.e. its production is closed complex.
- the specific performance of the known Blower not sufficient for many uses.
- the technical problem underlying the invention therefore exists in creating a high pressure blower that operates at limited Dimensions, which are usually determined by the device in which the blower is used, are predetermined and the use of a Large series engine generates the highest possible pressure and yet is easy to set up and manufacture.
- High pressure blower a device for measuring the volume flow contains.
- this technical problem has the following features solved :
- Such a high pressure blower produces despite being relatively low Dimensions a high pressure and a large volume flow. It is also with a device for measuring the throughput volume Mistake.
- the high-pressure blower is arranged in the tubular casing 1, which for example has an inner diameter of 150 mm.
- the high pressure blower mounted in the casing containing the electric motor 1 2, for example a DC motor with a target rotation speed of 5,000 min -1.
- the disk-shaped inflow nozzle 3 On the output side of the electric motor 2 there is the disk-shaped inflow nozzle 3, which has a circular opening 5 in the area of the motor shaft 4.
- the inflow nozzle 3 is provided with the annular channel 6, which has an annular slot 7 towards the opening and is connected via the opening 8 to the connection A outside the tubular casing 1.
- the space above the inflow nozzle 3 is connected via connection B to the space outside the tubular casing 1.
- Differential pressure values can be measured between ports A and B, which are proportional to the volume flow of the high-pressure blower (quadratic function).
- the impeller is connected to the motor shaft 4. It consists of the flat rear plate 10 provided with a plate-like edge 9, the flat front cover plate 11 and the blades 12 arranged between them, which should be curved, for example, backwards.
- the deflection disk 13 is arranged after the impeller. She owns a slightly smaller diameter than the impeller. Between her The circumference and the inner diameter of the tubular shell 1 is a Forming flow path narrowing annular gap 14.
- FIG. 2 shows a high-pressure fan, which is constructed in the same way as the high-pressure fan in FIG. 1.
- the same components are provided with the same reference numerals.
- the electric motor 2 is arranged behind the other parts in the direction of flow.
- the proposed high-pressure blowers are particularly suitable, for example, for being assembled with a gas burner.
- blower for example in Fig. 3.
- the Components of this blower which are identical to those in FIGS. 1 and 2 Blowers shown are identical, are given the same reference numerals Mistake.
- the motor 2 is attached to a closed wall 15 so that an inflow space 18 is present between it and the inflow nozzle 3.
- the air required to form the gas-air mixture becomes the Inflow chamber 18 fed radially, as illustrated by the arrows 19.
- the gas is supplied via the feed pipe A 2, which is connected to the ring channel 6 communicates. It passes through the ring channel 6 the slot 7 into the inlet nozzle 3.
- the slot 7 only extends over part of the circumference of the inlet nozzle 3, for example over 340 degrees.
- the lid 20 can be hemispherical Be sieve bottom.
- the inlet nozzle of the High pressure blower on two ring channels As can be seen from Fig. 3, the inlet nozzle of the High pressure blower on two ring channels.
- the upper ring channel 21, which is provided with the connection piece A 1 is used for acceptance a control pressure.
- the size of the one taken off at the connector A 1 Pressure is proportional to the volume of air delivered.
- the wall 15 is interposed of a tube 16 provided with an external thread is a conical one Throttle device 17 is provided.
- This throttle device 17 is axially adjustable by twisting so that they are within of a certain area in different positions to the inlet nozzle 3 can be brought.
- the throttle device can for one existing negative pressure in the ring channels within a certain Range of different volume flows or different air volumes can be set. Because there is a correlation between air volume and Burner output, the maximum burner output at a predetermined fan speed and a predetermined differential pressure continuously adjustable between A 1 and B.
- Fig. 5 shows the top view of the underside of the impeller cover plate not present. It is the rear pane 10 with to recognize the backward curved blades 12.
