Description

Pelton Impact Turbine

technical field

The utility model relates to the technical field of water conservancy engineering machinery, in particular to a bucket impact water turbine.

Background technique

my country is a country with complex and diverse terrain, and there are mountains and other rivers with large drops in the complex terrain. Therefore, using hydropower to generate electricity is an important way for my country to effectively use resources to create energy. The water inlet pipe of the existing water turbine is usually set directly to the water wheel, and the water wheel is mostly in the form of blades, and the potential energy provided by the head of the water source is converted into mechanical energy. In this way, the utilization rate of resource energy is very limited, and a large amount of hydraulic power is not sufficient. Being utilized, resulting in a large amount of waste of water resources. In today's world where energy is increasingly scarce, how to save energy and make full and effective use of energy is an important issue that must be resolved at this stage.

Contents of the invention

The technical task of the utility model is to solve the deficiencies of the prior art and provide a bucket impact water turbine.

The technical scheme of the utility model is realized in the following manner. The bucket impact water turbine includes a casing, a runner, and a water inlet pipe. There is a vane bucket, a water inlet pipe is arranged on one side of the casing, a nozzle is arranged at one end of the water inlet pipe leading to the inside of the casing, a needle valve is arranged inside the nozzle, and a regulating valve is arranged on the water inlet pipe outside the casing.

The opening directions of the buckets on the runner are consistent.

The nozzle is arranged under one side of the runner, and the nozzle is arranged on the tangential direction of the circle formed by the center of the bucket of the runner.

The number of buckets on the runner is 16.

The utility model has the advantages that: the bucket impact water turbine uses the water volume regulating valve and the needle valve in the nozzle to control the flow rate and flow rate of the water on the water inlet pipeline, and can make full use of the potential energy of the water to convert it into mechanical energy. High efficiency, the setting of 16 blade buckets on the runner of the water bucket impact turbine, firstly increases the density of blade buckets, which is conducive to improving work efficiency, and moreover, the setting of blade buckets can fully utilize the water energy Converted into mechanical energy, it is suitable for high water head power stations. The single unit capacity ranges from more than 10 kilowatts to more than 200,000 kilowatts. It has a simple structure and stable performance.
