Fan for conveying media

Abstract: The blower has a sealing (22) arranged at a side of a rear front wall (8) of a housing in such a manner that the sealing in a position, which seals an opening gap, lies against a through hole under axial prestressing at the rear front wall of the housing in a sealed and surrounded manner. The sealing includes a clamping element (32) made of spring-elastic material i.e. spring steel, and a sealing element (23) made of non-elastomer material i.e. PTFE, where the sealing element is fixed between the clamping element and the rear front wall in a force-fit manner.

Verfahren zum Regeln von Ventilatoren sowie Ventilatorgruppe

Abstract: Die Erfindung betrifft ein Verfahren zum Regeln einer Ventilatorgruppe zur Erzeugung eines vordefinierten Gesamtvolumenstromes vorgeschlagen, wobei die Ventilatorgruppe aus einer Vielzahl von parallel betriebenen einzelnen Ventilatoren besteht, die jeweils einen Einzelvolumenstrom erzeugen. Die Ventilatorgruppe ist in mindestens eine erste und wenigstens eine zweite Regelgruppe aufgeteilt, die jeweils mindestens einen Ventilator umfassen. Unter Einhaltung eines im Ergebnis konstanten Gesamtvolumenstromes wird der Einzelvolumenstrom des mindestens einen Ventilators der ersten Regelgruppe durch eine Regelung in einen Bereich des optimalen Wirkungsgrades durch eine Drehzahlveranderung erhoht und der Einzelvolumenstrom des mindestens einen Ventilators der zweiten Regelgruppe durch Drehzahlverringerung entsprechend reduziert. Dabei ist vorgesehen, dass jederzeit alle Ventilatoren einen Beitrag zum Gesamtvolumenstrom leisten und zu keinem Zeitpunkt eine Abschaltung eines Ventilators der zweiten Regelgruppe erfolgt. Die wenigstens eine erste Regelgruppe ist innerhalb seiner hochsten Leistungsaufnahme in sein Wirkungsgradoptimum geregelt, so dass die Energiebilanz des Gesamtsystems der Ventilatorgruppe optimiert ist.

A air absorbing nozzle for fan

Abstract: The utility model relates to an air absorbing nozzle for fan with an induction port (8) for aspirating the fan primary air, air absorbing nozzle (2) have and border on the opening marginal zone section (7) of induction port (8), opening marginal zone section has at least one local breach portion (11), and air current plug -in components (10) can be fixed by detachably opening marginal zone section (7) in the breach portion (11), the air current plug -in components form provide for the bypass air current of inward -remittance fan primary air, access to the bypass of induction port (8) install measuring device (30) that are used for confirming the volume flow rate of fan primary air in the bypass. The utility model discloses integrate volume flow rate measuring device's solution on depositing the fan, even this solution also has low as far as possible error or allowable error under little volume flow rate's the condition.

Airflow fence and fan

Abstract: The utility model relates to an airflow fence and fan, wherein this airflow fence has around the lattice structure of axis, this lattice structure include interval distribution on the circumferencial direction radial check fence and in footpath upwards interval distribution's coaxial circumference check fence and outer lane, wherein the air inlet side of this airflow fence is extended to the plane and is on a parallel with the radial plane of this airflow fence Consequently, need less space in the axial, maintain the same efficiency simultaneously at least to at least, can not increase the noise discharges In addition, the fan that will have corresponding airflow fence improves to compact constitutional unit

Electric motor, internal rotor and rotor plate

Abstract: An internal rotor (150) for an electric motor (100) has a laminated rotor core (200; 600) with a multiplicity of rotor plates (310), which laminated rotor core (200; 600) has multiple pockets (210) in each of which a rotor magnet (221; 621) is at least partially arranged. The rotor plates (310) have first recesses (211; 611) for forming the pockets (210) and at least a first rotor plate (11) which has at least a second recess (231-236; 631), which second recess (231-236; 631) is assigned to a first recess (211-216; 611), wherein a sprung web-shaped clamping element (291; 691) is formed between the second recess (231-236; 631) and the assigned first recess (211-216; 611), which clamping element (291; 691) is tensioned towards the second recess (231-236; 631) by the assigned rotor magnet (221, 621), and which clamping element (291; 691) as a result applies a force to the assigned rotor magnet (221; 621) toward the first recess (211-216; 611) in order to hold the assigned rotor magnet (221; 621) in the pocket (210). A rotor plate (311) for holding a rotor magnet (221) in a pocket (210) of a laminated rotor core (200; 600) is also presented.
