摘要： A pumping system in which a pump (5) is controlled by a programmed controller (22) in response to input signals from an inlet pressure transducer (3) and an outlet pressure transducer (15) and in certain circumstances inputs from various flow sensors (4,19). The controller (22) can be programmed to allow the pump (5) to prematurely operate before an outlet pressure reaches a low pressure threshold, when usage of the liquid is high. The controller (22) can be programmed to detect a lack of prime of the pump (5), to restore prime once the pump (5) has lost prime, and to prevent successive on/off pump cycles when the outlet flow is continuous and at a moderate or low level.

摘要： A centrifugal pump has a rotating shaft (1) with a centrifugal impeller (3) mounted on it. The shaft (1) and impeller (3) are mounted within a stationary casing (7) and a mechanical seal (8) is provided where the shaft (1) passes out through the casing (7). In order to cool rubbing, sealing faces (9, 11) of the seal, fluid is caused to flow along a path from a tip (6) of the impeller, through the casing (7), into a seal chamber (14), through a clearance (15) between a hub (2) of the impeller and the casing (7) and returning through a port (16) in the impeller. In order to act as a vent for and to clear debris from the seal chamber (14), the clearance is located radially outwardly of and remote from the shaft (1). Especially those parts which are moving and are subject to wear can be replaceable.

摘要： A water supply system that supplies water to a plumbing system from either a mains supply, or an auxiliary supply. In a default state, a shuttle valve is pressure balanced and couples water from the mains supply to the plumbing system via mains inlet port and outlet port, and in another state the shuttle valve is pressure unbalanced and moved so that auxiliary water is coupled to the plumbing system via an auxiliary inlet port and the outlet port of the shuttle valve. Water is drawn from an auxiliary tank and coupled to the plumbing system when two conditions exist, namely when water is demanded, as sensed by flow sensor, and when water is available from the auxiliary supply, as sensed by float system. Water pressure at the auxiliary inlet port causes the shuttle to move from the default state and couple water from the auxiliary inlet port to the outlet port and thus to the plumbing system. When either of the two conditions are not met, the shuttle valve remains in the default state and couples mains water from the mains inlet port to the outlet port and thus to the plumbing system.

摘要： A method of degassing a coal seam by directionally drilling a borehole in a rock formation that is adjacent the coal seam, or between two different coal seams. The borehole is then pressurised to fracture the adjacent coal seam(s) to enhance the permeability thereof and allow fluids to flow from the coal seam to the borehole and be extracted from the coal seam.

摘要： A drill bit (6) is equipped with one or more fluid jets (7) that are activated during a portion of the rotational movement of the drill bit (6). A processor (41) located with other down-hole sensors (33-38), is programmed with parameters defining the desired path of the borehole (8). The sensors (33-38) determine the actual spatial location of the drill bit (6) and provide the processor (41) with corresponding information. The processor (41) compares the actual drilling path to the desired path, and if a correction is required, a switching module (3) allows a pressurized drill fluid to be sequentially switched to selected jets (7) during rotation of the drill bit (6) to thereby erode the formation in a direction toward the desired path. With this arrangement, the problems of directional control by surface-located equipment are overcome.

摘要： A borehole drilling apparatus has a jacket attachable to a well head and through which a drill rod passes and which carries pressurized drilling fluid to a working end of the drill rod and out into an annulus of the borehole. The jacket has a drill rod seal and an outlet port leading from the interior of the jacket to a pressure regulator. The pressure regulator comprises an annular space through which fluid can flow from an inlet to an outlet. The annular space is defined between an inner rod and a surrounding elastomer pipe. In use, the elastomer pipe is squeezed radially inwards toward the inner rod by fluid pressure maintained between the outside of the elastomer pipe and a surrounding housing. A sampling system is in communication with the outlet port at a location upstream of the regulator. The sampling system intercepts a proportion of the drilling fluid passing to the regulator for enabling sorption pressures, gas contents, bubble points or other characteristics of the return fluid and entrained contents to be determined.

摘要： A method and device for stimulating and completing a drilled wellbore in a productive formation. The device comprises a pipe having a plurality of weakened portions and containing a propellant material. When the propellant is ignited it produces rapidly expanding gaseous combustion products which puncture the weakened portions of the pipe. The expanding gas fractures the surrounding formation thereby stimulating the formation to production. The pipe remains in the wellbore and is used for collecting oil and gas from the formation.

摘要： A steering collar for deflecting a drill string in a borehole to cause the borehole to be drilled in a different direction. The steering collar surrounds a hollow drive shaft which is driven by the drill string. During normal drilling operations, the steering collar does not rotate with the drive shaft. The steering collar has three sets of pistons operated by the pressure of the drilling fluid, one set of which is pressure relieved. Drill fluid that is pumped down the drill string flows into the hollow drive shaft and through ports to activate the pistons which thereby force corresponding pads outwardly into contact with the sidewall of the borehole. Since the one set of pistons is pressure relieved, it does not force its pad against the borehole sidewall with as much pressure as the other two sets of pistons force their pads against the sidewall of the borehole. Accordingly, the steering collar is deflected laterally in the borehole so that the drill bit is also steered laterally to cause drilling in a different direction. In order to reorient the steering collar in the borehole, the steering collar can be locked to the drive shaft so that when the drill string is rotated, the steering collar is also rotated so that it is moved to a new angular position in the borehole.
