Problems solved by technology

[0003] At present, the existing fire extinguishing equipment cannot be used in harsh environments. For example, when the water level is greater than 3-5 meters, the fire extinguishing equipment cannot take water from the outdoor seaway to extinguish the fire
Because most of the water pumps used by fire extinguishing equipment currently have a water absorption depth of 3-5 meters. When the water level in the river is lower than this depth, it often cannot meet the requirements of water absorption and fire extinguishing, which limits the use of fire fighting equipment.

Embodiment 1

[0024] Such as figure 1 As shown, the hydraulically driven centrifugal pump of the present invention includes a centrifugal water pump and a water turbine, wherein the water turbine and the centrifugal water pump are coaxially installed.

[0025] Wherein, the centrifugal water pump includes a pump body 1 , a pump cover 3 , an impeller 2 and a rotating shaft 4 . The structure of the pump body of the centrifugal water pump is as follows: figure 2 , image 3 shown.

[0026] Wherein, the water turbine includes a pump cover, a volute 6 and a runner 7 . The volute structure of the turbine is as Figure 4 , Figure 5 shown.

[0027] The impeller of centrifugal water pump and the coaxial of water turbine are installed on the two ends of above-mentioned rotating shaft 4, and shaft sleeve 4 is equipped with in the middle part of rotating shaft 4, and its impeller is installed on rotating shaft 4 front ends through bearing 8. The running wheel 7 is installed on the rear end of t...

Embodiment 2

[0029] Working process of the present invention is as follows:

[0030] When working, the water driven by the power source enters the water turbine through the hydraulically driven water inlet QT1, and is discharged through the hydraulically driven water outlet QT2 to form a water cycle. The runner of the wheeled water turbine rotates, and then drives the rotating shaft of the present invention to work, and the rotating shaft drives the impeller of the centrifugal water pump to rotate, which is used as a water supply pump. The water supply of the centrifugal water pump is sucked through the pump water inlet QP1 and discharged from the pump water outlet QP2.

[0031] The hydraulic driving part of the water turbine can adopt a circulating water pump as a power source to provide the power of the present invention.

[0032] Driven by the water turbine, the centrifugal water pump can supply water to the fire fighting equipment.

[0033] The test data of hydraulic drive centrifuga...

Abstract

The invention provides a water-power-driving centrifugal pump which is wide in an application occasion range. After the pump is driven, the depth of water pumping can reach above 20 meters, and the pump can meet water pumping requirements under the severe environment. The water-power-driving centrifugal pump comprises a centrifugal pump and further comprises a water turbine. The centrifugal pump and the water turbine are installed in a coaxial mode. The centrifugal pump comprises a pump body, a pump cover, an impeller and a rotary shaft. The water turbine comprises a pump cover, a volute and a turning wheel. The impeller and the turning wheel are installed at the two ends of the rotary shaft in a coaxial mode, the impeller is installed at the font end of the rotary shaft and connected through a bearing, and the turning wheel is installed at the rear end of the rotary shaft and connected through a bearing. A shaft sleeve is installed in the middle of the rotary shaft. The pump cover of the centrifugal pump and the pump cover of the water turbine are connected to cover the rotary shaft and shaft sleeve.

Description

technical field [0001] The invention relates to a hydraulic drive device, in particular to a hydraulic drive centrifugal pump. [0002] Background technique [0003] At present, the existing fire extinguishing equipment cannot be used in harsh environments. For example, when the water level is greater than 3-5 meters, the fire extinguishing equipment cannot take water from the outdoor seaway to extinguish the fire. Because most of the water pumps used by fire extinguishing equipment have a water absorption depth of 3-5 meters, when the water level in the river is lower than this depth, it often cannot meet the requirements of water absorption and fire extinguishing, which limits the use of fire protection equipment. Contents of the invention [0004] Aiming at the existing technical situation, the present invention provides a hydraulically driven centrifugal pump. The pump is suitable for a wide range of occasions, and the water absorption depth can reach more than 20 met...
