摘要:
Die Wasserpumpe (4) und die Schaummittelpumpe (7) werden in einer Kompaktanordnung zueinander auf einer einzigen Welle (9) oder einem Wellenstrang (10) angetrieben, die bzw. der vom Motor (3) des Kraftfahrzeugs angetrieben wird. Dadurch ergibt sich eine sehr kompakte Bauweise, ein sehr geringer Regelaufwand und eine einfache Verrohrung.
摘要:
Die Erfindung betrifft eine Einrichtung für Feuerlösch-Fahrzeuge mit einem automatischen, elektronisch gesteuerten Zumischer (21), mit dem ein Schaummittel (12) aus einem Vorratsbehälter (11) dem Löschwasser (4) in einer vorbestimmten Menge beigemischt wird. Das Schaummittel (12) wird elektronisch geregelt dem Löschwasserstrom in einem wählbaren Verhältnis zugemischt, wobei die prozentuale Zumischung unabhängig vom Wasserdurchfluß konstant bleibt.
摘要:
A first intervention mobile unit for contaminated areas is described, including an air-tight closed motor-van (1) with a suitable trailer (2). in which is provided a set of equipment capable of allowing a certain number of operators (4) to intervene in said contaminated areas by means of connection (11) with said unit for respiration and communication.
摘要:
A digital computer based control system for a turntable ladder mounted on a vehicle is arranged to limit extension and minimum elevation angle of the ladder in accordance with the intended loading of the ladder. The system performs initial checks on parts of the system and will permit only manual control at low speed where the operational state of a part involved is unsatisfactory or outside the limits. In addition to monitoring the stabilising jacks on the vehicle and preventing movement of the ladder which would tend to increase an excessive bending force on it, the system automatically plumbs the ladder so that its rounds are horizontal. The system can also be applied to control a cage or platform on a telescopic boom.
摘要:
An extinguishing device comprises a body structure (101) having a vertical part (102) and a horizontal part (103), and a movable part (104) moveably supported to the vertical part to be above the horizontal part. The movable part is linearly moveable in a vertical direction to vary a distance between the movable part and the horizontal part so that an object in fire is between the movable part and the horizontal part. The extinguishing device comprises a hose connection (105) for receiving firefighting water from an external hose. The extinguishing device comprises first pipes (106) connected to the hose connection, attached to the horizontal part of the body structure, and provided with first nozzles (107) configured to spray the firefighting water upwards, and second pipes (108) connected to the hose connection, attached to the movable part, and provided with second nozzles (109) configured to spray the firefighting water downwards.
摘要:
Pump system (1) for a firefighting mixture generation system, comprising a housing (2) defining at least a pair of portions (2', 2") each defining a respective space (3', 3") and comprising a piston (4', 4") configured to slide in a fluid tight manner in each of the space (3', 3") and a crankshaft system (11', 11") configured to rotate about a respective axis (B', B " ) to move pistons (4 ' , 4") along a common travel axis (A), wherein spaces (3', 3") are fluidly connected together to define a delivery volume (6), the pump system (1) comprises regulation means (15) configured to vary the angular phase between the crankshaft systems (11', 11 " ) of pistons (4', 4") to vary the delivery volume (6) while crankshaft systems (11', 11 " ) is maintained constant.
