Abstract:
A cleaning device (1) of the type operating by means of a pair of hydraulic nozzles (2), each nozzle spraying a cleaning liquid jet which carries out a swabbing action, allowing a considerable handling flexibility by making the nozzles (2) substantially independent from each other, and comprising an operative end (3) for handling said hydraulic nozzles (2); and a feeding unit (4) operating said hydraulic nozzles (2) by unwinding and winding a pair of hoses (5), each tube being connected to the respective hydraulic nozzle (2), comprising a reel (21), wherein said hoses (5) are wound; one or more motor-driven rotating elements (23) for moving said hoses (5) forward and backward; a drive shaft (30) controlled by a reversible mover (29), mechanically connected both to the reel (21) and the rotating elements, so as to provide them with the same direction of rotation, said reel (21) being connected to said drive shaft (30) by a first power chain (31, 32, 34, 36) which operates when the hoses (5) are moved backward, with said rotating elements being independently connected from each other to said drive shaft (30) by respective second power chains (31, 33, 35, 37) which operates when said hoses (5) are moved forward.
Abstract:
A method and an arrangement for controlling cable winding and unwinding in an electrically driven vehicle. In the method, cable winding and unwinding, respectively, are controlled on the basis of the position of driving and/or steering means of the vehicle. The arrangement comprises only one unwinding valve (7) connected in series with a hydraulic motor (4), by which valve the counterpressure of the hydraulic fluid flowing through the hydraulic motor (4) can be regulated during cable (2) unwinding from the reel (1), and one winding valve (6) respectively, by which the quantity of the hydraulic fluid coming to the hydraulic motor (4) can be regulated during cable (2) winding.
Abstract:
The present disclosure is to systems and methods for actuating pneumatic controls of reels electronically via a remote console, thus expanding remote control capabilities in a combination of hazardous and undesignated areas for oil and gas technologies. The method includes receiving, at a second control network (110) from a first control network (105), electrical control signals for controlling pneumatic solenoids (145) of a second control network (110). The second control network (110) provides pneumatic signals to pneumatic valves (165), based at least in part on the control of the pneumatic solenoids (145). A controlling feature of the present disclosure is based at least in part on the pneumatic signals, to control, via the pneumatic valves (165), spooling movement of one or more reels (170) comprising cables or feed lines, thereby spooling the cable or the feed lines.
Abstract:
The application concerns a control unit (1) and its for positioning a wash-down hose (2) with flushing nozzle (3) for cleaning of waste-water pipes, in which the wash-down hose (2) is mounted on a cylindrical wash-down hose drum (4) with an axial length and where the wash-down hose drum has a rotational position, wherein the unit includes a pulse emitter (5), a rotation direction indicator (5a) and a memory unit (6), in which: - the pulse emitter (5) is designed for emitting a fixed number of electrical pulses per rotation of the wash-down hose drum (4), - the rotation direction indicator (5a) is designed to determine a rotation direction for the wash-down hose drum (4), and - the memory unit (6) is designed with an address for storing data related to the electrical pulses from the pulse emitter (5) and from the rotation direction indicator (5a) for determining the rotational position of the wash-down hose drum (4), where the storing of data is maintained independently from power supply to the memory unit (6). With the control unit an improved control is achieved of a flushing process of a waste-water pipe.
Abstract:
A vacuum pool-cleaning storage system that is housed in the side of a swimming pool substantially below the waterline. The pool vacuum cleaner automatically deploys to clean the pool when the central pool vacuum pump is activated, and automatically retracts to a stored position when the central pool vacuum pump is turned off. The system is adapted to store the vacuum hose in a substantially linear tube located substantially underground. A reel-type hose storage embodiment is also disclosed. The system is preferably powered by vacuum pressure generated by a water circulation pump of the pool plumbing system.
Abstract:
The invention relates to a device for the internal coating of pipes, in particular coolant pipes of vapour condensers and heat exchangers, with plastics. Said device has a supply unit (V) for feeding and forwarding coating material, an application unit (A) for applying the coating material fed by the supply unit, and a control unit for monitoring and controlling the supply with coating material and the application of said coating material to internal pipe walls. The application unit (A) has guide tubing (21) with a mouthpiece (29) mountable on the pipe to be coated, and an application tubing (18) conveyed in the guide tubing (21), insertable through the mouthpiece (29) into the pipe to be coated and having an application nozzle (30).
Abstract:
A buoyant conduit storage system comprising a reel for storing conduit and a drive arrangement for rotating the reel. The reel is rotatable about a substantially vertical axis of rotation to reel and/or unreel the conduit.The drive arrangement drives the reel at the axisof rotation. The buoyant storage system may provide for the storage and/or transportation and/or deployment of reelable conduit.
Abstract:
A pump positioning and driving vehicle for remote sites such as mines having a trailer with a jib for raising and lowering a water pump down the face of a site to submerge the pump which rides on a cart with wheels. The cart is connected to the trailer by a pair of hoses which are wound on a reel. A hydraulic generator on the trailer supplies power to the pump through the hoses which return water output from the pump to the trailer where it discharges into a drainage conduit. In a variant, the trailer has an electrical generator and one of the hoses contains an electrical cable for driving an electric pump motor. The trailer wheels rise hydraulically to allow the trailer to lie on the ground.
