摘要: A rotary hydraulic machine with radial pistons comprising: a rotating shaft (2); a cylinder-housing body (3), having a plurality of housing seatings (4) arranged radially at equal distances from the rotation axis (R) of the rotating shaft (2); a cylinder (5) housed in each of said plurality of housing seatings (4) and rotating relative to the same around an axis (C) concentric with said rotation axis (R) of the rotating shaft (2); a piston (6) slidable in each cylinder (5) and coupled to a crank (7) of the rotating shaft (2); a supply conduit (12), for each cylinder (5), provided with a seal (120) arranged to enable a sealed connection between the supply conduit (12) and the respective cylinder (5). Each seal (120) comprises: a first ring (121), arranged at an end of the supply conduit (12) and placed in contact with the cylinder (5); a second ring (122), concentric to the first ring (121) and interposed between the supply conduit (12) and the first ring (121), wherein the second ring (122) is coupled by interference with the first ring (121) and is inserted by interference into the supply conduit (12) in such a way as to prevent a rotation of the first ring (121) with respect to the supply conduit (12) around a common axis (X).

摘要: A hydraulic machine including: a casing rotatably mounted relative to a shaft; first brake means constrained to rotate with the casing; second brake means constrained to rotate with the shaft, and adapted to co-operate with the first brake means; a braking piston associated with return means and tending to exert a braking force; and a brake-release chamber adapted to be connected to a pressure force so as to apply a brake-release pressure selectively to the braking piston, so as to enable the first and second brake means to be separated; said hydraulic machine including a sweeping channel arranged in the shaft so as to define a leakage flow between the brake-release chamber and an internal volume of the casing.

摘要: A liquid leak detector for a pump is described. The liquid leak detector is mountable on a pump to detect leaked fluid coming from the pump. The leak detector includes a buffer tube positioned on the pump to collect a leaked fluid from the pump and a sensor positioned on the buffer tube to detect the level of leaked fluid in the buffer tube and to generate a signal when the leaked fluid reaches a maximum fluid level. A purge line on the buffer tube removes leaked drive fluid from the buffer tube once the leaked drive fluid reaches a maximum level. Logic connected to the sensor receives the signal from the detector and generates an alarm.

摘要: A suction cover assembly for a reciprocating pump includes a suction cover nut having a nut face and a thread configured to threadably connect the suction cover nut to a fluid cylinder of the reciprocating pump. The suction cover assembly includes a suction cover having a cover face. The suction cover is configured to be held by the fluid cylinder such that the cover face opposes the nut face of the suction cover nut. The suction cover includes first and second seals having a leakage trap defined therebetween. The leakage trap is configured to trap leakage pressure during operation of the reciprocating pump. The suction cover includes at least one leakage channel that is configured to channel the leakage pressure from the leakage trap to an interface between the cover face and the nut face.

摘要: Vibrating pump with a secondary closed circuit designed for the recovery and reinjection of the fluid that can eventually escape from the compression chamber and which, if not collected, would end up in the force chamber affecting the drive elements (springs, magnetic core) and therefore the proper functioning and useful life of the pump.

摘要: A pump drip control system for attachment to a pump assembly to prevent premature replacement of the pump. The control system includes a pump housing having a leakage collection chamber and a drip cap engaged with a second end of the leakage collection chamber. The drip cap includes a circumferential channel defining a flow path to a gathering chamber. The pump drip control system further includes a slinger assembly located within the leakage collection chamber, and wherein, in operation, the slinger assembly directs liquid leakage from the impeller shaft to the drip cap and the circumferential channel within the drip cap which directs the liquid along the circumferential flow path and into the gathering chamber. The gathering chamber can hold a predetermined amount of liquid until the liquid evaporates and includes a liquid exit port for draining excessive liquid out of the pump housing to another location.
