摘要:
A fluid pump includes a pump body having a fluid path with an inlet and an outlet. The fluid pump also includes a diaphragm disposed along the fluid path between the inlet and the outlet, a non-return valve to control direction of flow along the fluid path, and a diaphragm actuating unit. The diaphragm actuating unit includes an unbalanced motor. Further, a steam generator may include the fluid pump.

A method comprises accessing a vibratory device having a rotor and first and second eccentric weights. The first weight is initially attached to the rotor's shaft in a manner such that its center of the mass is offset from the shaft in a first radial direction. The second weight is initially attached to the shaft in a manner such that its center of the mass is also offset in the first radial direction. The method further comprises reorienting the first and second weights relative to the shaft in a manner such that their centers of the mass are offset in a second radial direction. By performing these steps, the location of greatest bearing surface wear rate on the shaft is circumferentially relocated about the shaft. As such, the service life of an eccentric weight vibratory device is thereby extended.

The invention relates to a controller for an unbalanced mass adjusting unit in a vibration exciter. Said controller comprises an adjusting piston (3) for changing the relative position of unbalanced masses in the vibration exciter (1) that is coupled to a reference piston (7). The position of a piston rod (10) of the reference piston (7) is detected by a pressure sensor (12) and is furnished to a controller (14) in the form of a position signal (13). The controller (14) compares the position signal (13) with an operating signal (15) given by an operator and generates a control signal (16) with which the position of a selector valve (18) that controls the oil supply to or the oil discharge from the reference piston (7) can be changed.

Bei einem Rotationsvibrator, dessen Unwuchten auf gegensinnig drehenden, parallelen Innenwellen angeordnet und in ihrer Exzentrizität über konzentrisch äußere Hohlwellen verstellbar sind, ist erfindungsgemäß vorgesehen, daß die Unwuchten (25, 26; 32) exzentrisch auf Exzentern (23, 24, 31) drehbar und in Radialarmen (27, 33, 34) der mit ihren Innenwellen (19, 22) gleichsinnig umlaufenden Hohlwellen (9, 10) geführt sind, welche über ein Planetengetriebe (15-17) gegenüber den Innenwellen (19, 22) verdrehbar sind.
摘要:
A pneumatic linear vibrator comprises a piston guide sealed at least on one side and delimited by detachable end parts (14, 16), a piston (10), a sound-absorbing pipe (52) which forms the housing, and means for supplying and removing a gaseous or vaporized pressure medium. Relative motion between the guide with the end parts and the piston is ensured by automatic alternating delivery of the pressure medium to a working to a working volume (V, V1, V2) located on one face of the piston. The piston (10) has a longitudinal axial bore (22) with a snap ring groove (26) in the region of the ends or close to either side of the longitudinal median plane of the piston. The snap ring grooves are connected to a face of the piston (10) by at least two axisymmetric channels (27) which run in the axial direction (A) and are sealed off from the longitudinal axial bore (22) of the piston (10). A guide pipe (18) for delivery of the pressure medium, which is closed at one end, penetrates the end part (14) or end parts (14, 16) and the longitudinal axial bore (22) of the piston (10) in a sealed manner. The guide pipe (18) serves as a piston guide and has radially disposed axisymmetric outlet openings (32) for the pressure medium corresponding to the snap ring grooves (26) in the longitudinal axial bore (22) of the piston (10). The vibrator has a slim, elongated shape and can be used for example for sieves, conveying channels compacting installations and for driving tools.

摘要:
Ein pneumatischer Linearvibrator umfasst eine durch mindestens auf einer Seite dichtendes, lösbares Abschlussteil (14, 16) begrenzte Kolbenführung, einen Kolben (10), ein das Gehäuse bildendes Schalldämpferrohr (52) und Mittel zur Zufuhr bzw. Abfuhr eines gas- bzw. dampfförmigen Druckmediums. Die Relativbewegung zwischen der Führung mit den Abschlussteilen und dem Kolben erfolgt durch selbststeuernde, alternierende Zufuhr des Druckmediums zu einem auf einer Stirnseite des Kolbens gebildeten Arbeitsvolumen (V, V1, V2). Der Kolben (10) weist eine längsaxiale Bohrung (22) auf, welche im Bereich der Enden oder beidseits benachbart der Längsmitte des Kolbens je eine Ringnut (26) hat. Die Ringnuten sind über mindestens je zwei axialsymmetrisch angeordnete, gegenüber der längsaxialen Bohrung (22) des Kolbens verschlossene, in Axialrichtung (A) verlaufende Kanäle (27) mit einer Stirnfläche des Kolbens (10) verbunden. Ein auf einer Seite verschlossenes Führungsrohr (18) für die Zufuhr des Druckmediums durchgreift den Abschlussteil (14) bzw. die Abschlussteile (14, 16) und die längsaxiale Bohrung (22) des Kolbens (10) dichtend. Das Führungsrohr (18) dient als Kolbenführung und weist entsprechend der Ringnuten (26) in der längsaxialen Bohrung (22) des Kolbens (10) in radialer Richtung angeordnete, axialsymmetrische Austrittsöffnungen (32) für das Druckmedium auf. Der Vibrator hat eine schlanke, längliche Form und kann beispielsweise für Siebe, Transportrinnen, Kompaktierungsanlagen oder zum Antrieb von Werkzeugen eingesetzt werden.
