Centrifugal pump

1522468 Helico-centrifugal pumps SUNDSTRAND CORP 18 April 1977 [7 May 1976] 15987/77 Heading F1C Two diffusers 21, 22 are provided to receive the discharge from the pump impeller 16, the larger diffuser 21 being closed at low flow-rates by means of an axially slidable sleeve valve 23. Each diffuser comprises two volutes, approximately 180 degrees apart, discharging to an outlet pipe 26 in the case of the diffuser 21 and to an outlet pipe 29 in the case of the diffuser 22. The pump supplies fuel to an aircraft engine. When a high fuel flow-rate is demanded, the engine fuel control unit 48 supplies a pressure signal via a line 50 to shift a spool valve 47 to the left to admit fuel from the outlet pipe 29 to a chamber 37 to counterbalance the pressure within a chamber 36, whereupon the difference between the pressures acting on the ends 31, 30 of the sleeve valve 23 shifts the latter to the right to open the diffuser 21.

A centrifugal pump draws liquid from an inlet opening and discharges the liquid from an outlet opening. The pump includes a casing having a pump chamber, the inlet opening, and the outlet opening, an impeller placed in the pump chamber, and a drive mechanism for rotating the impeller. In the centrifugal pump, the impeller is placed so as to form a gap between the inner surface of the pump chamber and the lower surface of a disc of the impeller. In the impeller is formed a hole at the center of the disc. The casing has in its side wall a communication hole adapted for communication between the pump chamber and the outside of the casing. Even if gas stays in the gap, the centrifugal pump constructed in this way can discharge the gas through the communication hole. The centrifugal pump has sufficient pump performance and can be reliably started without becoming inoperable in starting operation.

Self-priming centrifugal pump

A self-priming centrifugal pump comprises a pump housing (2) having at least one inlet (3) and one outlet (4) for a working fluid, an impeller (5) rotatably mounted in the housing (2) and mounted to a shaft (6) having a longitudinal axis (L), prime mover means acting on the shaft (6) to rotate the impeller, a volute (7) placed inside the pump housing. The volute (7) has an inner spiral chamber (8) with a predetermined axial extension, a suction port (9) in fluid communication with the inlet (3) and a discharge port (10) in fluid communication with the outlet (4) . The spiral chamber (8) is delimited by a substantially continuous outer peripheral wall (11) with no recirculation port. Furthermore, the axial extension of the spiral chamber (8) is greater than or equal to that of the impeller (5). The advantage is obtained of providing fluid recirculation in the volute (7) and a negative pressure in the inlet during the self-priming step, substantially with no additional volumetric loss.

Группа изобретений может быть использована для разработки траншей под водой. Насосное устройство содержит основной насос с входом и выходом текучей среды соответственно низкого и высокого давления, и средство, связанное с входом среды основного насоса, эксплуатируемое в случае, когда внешнее давление является недостаточным для предотвращения кавитации в основном насосе, для локального увеличения давления среды на входе основного насоса. Устройство содержит один или более регулируемых клапанов ограничения потока, расположенных ниже по потоку от выхода среды высокого давления. Клапаны имеют положение, ограничивающее поток, и положение, не ограничивающее поток, где указанное положение, ограничивающее поток, функционально снижает входящий поток в основной насос и увеличивает давление выпуска на выходе текучей среды основного насоса в сравнении с положением, не ограничивающим поток. Один или более регулируемых клапанов сообщаются посредством трубопровода для обеспечения взаимодействия среды с основным выходом среды. Изобретения направлены на снижение или устранение кавитации в насосном устройстве для струйного инструмента прокладки траншей при использовании его на мелководье. 3 н. и 9 з.п. ф-лы, 1 ил.
