摘要:
System (100) zur Reinigung und/oder Inspektion einer Rohrleitung (D), aufweisend einen Schlauch (1); eine mit einem Ende (1A) des Schlauchs (1) verbundene Arbeitsvorrichtung (2) zur Durchführung der Reinigung und/oder Inspektion mit einer Sensoreinrichtung (3), dazu eingerichtet, eine Bewegungsrichtung (X1, X2) der Arbeitsvorrichtung (2) in der Rohrleitung (D) repräsentierende Sensordaten zu erfassen; eine Schlauchtrommel (4), auf welche der Schlauch (1) auf- und abwickelbar ist; umfassend Motor (5), welcher dazu ausgebildet ist, die Schlauchtrommel (4) zu drehen und eine Steuerungsvorrichtung (6), welche mit der Arbeitsvorrichtung (2) und dem Motor (5) signalleitend verbunden und dazu eingerichtet ist: basierend auf den Sensordaten die Bewegungsrichtung (X1, X2) der Arbeitsvorrichtung (2) in der Rohrleitung (D) zu ermitteln und ein erstes Steuersignal an den Motor (5) auszugeben, welches den Motor (5) dazu veranlasst, die Schlauchtrommel (4) zum Aufwickeln des Schlauchs (1) in einer ersten Drehrichtung zu drehen, wenn die ermittelte Bewegungsrichtung der Arbeitsvorrichtung (2) einer vorbestimmten ersten Bewegungsrichtung (X1) entspricht.
摘要:
An intelligent pig for pipeline monitoring comprises a single body (1) containing signal transmitters and receivers provided with replaceable rings (5, 6, 7, 8) for centering the body (1) within the pipeline, the rings (5, 6, 7, 8) may be provided with brushes (9) which help centre the pig within the pipeline and also aid its passage through pipelines which may contain bends and/or be of variable diameter, the pig may be used in combination with a cleaning pig to provide combined activities using a common driving force.
摘要:
A multipurpose air tool (1) having a handle (2) to which a head (3) can be removably attached. The head (3) has attached thereto various tools such as a face plate (4) and replaceable nozzles (5). The head (3) is interlocked to the handle (2) by a spigot (19) and bayonet connection (21, 23, 34). A safety interlock (16) prevents operation of the trigger (15) and valve (12) unless the head (3) is correctly positioned on the handle (1).
摘要:
A projectile launcher is disclosed and claimed adapted for use in apparatus for cleaning tubes arranged in an array such as with heat exchanger tube bundles, the apparatus being of the type whereby a projectile (1) is placed in a tube (10) to be cleaned and then subjected to a sudden cleaning medium pressure impact to force the projectile (1) through the tube (10) at high speed, the launcher for such projectiles having a barrel (3) that is aligned with the tube to be cleaned, a magazine (2) for feeding serially projectiles (1) into the barrel (3), a duct (4) for supplying cleaning medium being movable through the barrel (3) to push a projectile (1) into the tube (11) to be cleaned, and means for supplying a pulse of cleaning medium along the aforesaid duct (4) once a projectile is positioned in the tube to be cleaned, the barrel (3) and the cleaning medium duct (4) being selectably removable from the launcher to be replaced with similar barrels and cleaning medium ducts to accommodate projectiles of differing diameters without loss of any operating fluids from the launcher.
摘要:
A pneumatic chuck comprises a casing (1) divided by a piston (2), oriented along its longitudinal axis, into an inlet chamber (3) and a pumping chamber (4). The inlet chamber (3) is connected to a compressed air source through an air supply pipe (6) passing through an axial opening in the piston (2). The pumping chamber (4) is connected to the inlet chamber (3) through an annular gap (7) between the air supply pipe (6) and the piston (2). At the moment of its evacuation the pumping chamber (4) is connected to the atmosphere. The cross-sectional surface (10) of the piston (2), facing the pumping chamber (4), is larger than that of the end-face surface (11) of the piston (2), facing the inlet chamber (3) but smaller than that of the end-face surface (12) of an annular projection (8) on the piston (2), facing the pumping chamber (4), an additional chamber (9) being formed on the inlet chamber (3) side by said projection and by the casing (1).
摘要:
It is disclosed a pig drive (110) and a pig drive system (100) for feeding a pig (120) into a pig kicker section of a pipe (200) and a method for using same. Wherein the pig drive (110) comprises: - a piston (111) with a radial direction and an axial direction; - a rod (112) connected to the piston (111) and extending in the axial direction of the piston (111), wherein the rod (112) has a distal end adapted to interface a pig (120); - a retainer (113) slidably connected to the rod (112) and adapted to interface a retainer abutment (132); and - a biasing device (114) arranged to bias the retainer (113) towards the distal end of the rod (112).
