Volute-spraying type water turbine

Abstract

The invention discloses a volute-spraying type water turbine, and belongs to the technical field of hydroelectric generation device designing and manufacturing. According to the volute-spraying type water turbine, the output effect can be remarkably improved. The volute-spraying type water turbine comprises a guide water spraying device and a water guide rotating device with a hydraulic driving mechanism. The guide water spraying end of the guide water spraying device is communicated with the driving water flow input end of the water guide rotating device. In the working process of the volute-spraying type water turbine, electric generation driving water flow is input into the water guide rotating device through the guide water spraying device, the electric generation driving water flow input into the water guide rotating device through the guide water spraying device drives the hydraulic driving mechanism to drive the water guide rotating device to rotate around the axial center line of the water guide rotating device.

Description

technical field [0001] The invention relates to a water turbine, in particular to a snail jet water turbine, and belongs to the technical field of design and manufacture of hydraulic power generation equipment. Background technique [0002] The water turbines in the prior art mainly include four types of impact water turbines, Francis water turbines, axial flow water turbines and perfusion water turbines. The above-mentioned several types of water turbines have been accumulated, improved, and finalized after years of accumulation. From a structural point of view, they are relatively perfect and most commonly used models. However, the above-mentioned types of water turbines also have obvious disadvantages, for example, due to structural reasons, the cost is very high, and the production cycle and maintenance cycle are relatively long. Equally, also be because the parts and components of the water turbine of said various types are all more, basically all comprise similar stru...

Problems solved by technology

However, the above-mentioned types of water turbines also have obvious disadvantages. For example, due to structural reasons, the cost is very high, and the production cycle and maintenance cycle are relatively long.

Equally, also be because the parts and components of the water turbine of said various types are all more, basically all comprise similar structures such as volute, runner, guide vane, front cover plate and rear cover plate, thereby make the output effect relatively small. Difference

In order to obtain the best output effect, it is required to be very precise and meticulous in manufacturing, which further increases the manufacturing cost.
