The present disclosure provides an irrigation system (1) for crop irrigation, and especially a centre-pivot irrigation system. The system comprises: a pivot assembly (10) comprising a frame (11) supporting an inlet pipe assembly (20) for inlet of water from a water supply to the irrigation system, and a span assembly (40) for connection to the pivot assembly (10) to extend radially therefrom across a field (F). The inlet pipe assembly (20) comprises an upper pipe segment (21) and a lower pipe segment (22). The upper pipe segment (21) is mounted in the frame (11) for rotation about a pivot axis (X) relative to the lower pipe segment (22). The span assembly (40) comprises a distribution pipeline (45) for fluid connection with the inlet pipe assembly (20) to convey the water along the span assembly (40) for distributing the water to a plurality of sprinkler heads located along the span assembly for applying the water to the field (F). The span assembly (40) is configured to rotate about the pivot axis (X) together with the upper pipe segment (21). The present disclosure also provides a pivot assembly (10) for a centre-pivot irrigation system (1), and a span assembly (40) for connection to a pivot assembly (10) in a centre-pivot irrigation system (1).

The fuel rail assembly comprising a fuel rail (4) comprising an elongate generally tubular body forming a fuel reservoir and having formed integrally therewith a fuel inlet port (6), and a plurality of fuel outlet ports (12) spaced along the fuel rail wherein each outlet port (12) comprises a fuel injector cup (10) adapted to receive a fuel injector. The fuel injector cup (10) is located on the fuel rail (4) by means of a connection device (14).
摘要:
Die Erfindung betrifft eine Verrohrung für eine Erdwärmesonde zur Gewinnung geothemischer Energie, insbesondere tiefengeothermischer Energie, wobei thermische Energie mittels eines vorzugsweise flüssigen Wärmeträgermediums aus einem tiefen Bereich in einen oberen Bereich der Erdwärmesonde transportiert wird, mit einem äußeren Förderrohr (13) aus einem Metall und mit einem innerhalb des äußeren Förderrohrs (13) vorgesehenen inneren Förderrohr (15) aus einem wärmeisolierendem Kunststoff, welches aus einer Mehrzahl von Innenrohrschüssen (15a) besteht, wobei das innere Förderrohr (15) an zwei oder mehreren axialen Positionen der Verrohrung (5) mittels jeweils einer Lastübertragungseinrichtung (23) zum Einleiten von auf das innere Förderrohr (15) wirkenden axialen Kräften auf das äußere Förderrohr (13) mit dem äußeren Förderrohr (13) verbunden ist. Erfindungsgemäß sind in axialen Sektionen zwischen zwei Lastübertragungseinrichtungen (23) die Innenrohrschüsse (15a) an Koppelstellen zwischen jeweils zwei unmittelbar benachbarten Enden der Innenrohrschüsse (15a) gekoppelt. Zusätzlich ist in jeder Sektion zumindest an einer Koppelstelle zwischen einer der beiden Lastübertragungseinrichtungen (23) und dem unmittelbar benachbarten Ende des betreffenden Innenrohrschusses (15a) eine Kopplung gegeben, wobei die Kopplung an den Koppelstellen ohne einen Stoffschluss durch axiale Druckkräfte erzeugt oder zumindest oder zumindest unterstützt wird.

摘要:
Λ method of making a hose is provided that includes providing a fitting configured to receive a hose liner therethrough and configured to receive a material configured to be bonded to the hose liner. The method includes receiving the material in the fitting, drawing the hose liner through the fitting, and bonding the material to the hose liner such that the hose liner and material arc secured to an outer face of the fitting.
摘要:
The invention relates to a method for assembling two structural elements, at least one of the two being tube-shaped and including a skin made of a fiber-reinforced composite material. The ability of said element to adapt to the shape and perimeter of the junction interface is improved by providing longitudinal grooves (5) distributed on the circumference of the junction interface. The grooves (5) are of a sufficient length to provide the junction interface with the flexibility to accommodate, through the relative radial movement of each portion located between two grooves, the differences in shape and perimeter among the junction interfaces of the two structural elements.
