What is the water bell effect of a hydrogenerator:

Water hammer effect

Water hammer occurs when there is a sudden power failure or when the valve is closed too quickly, due to pressure flow inertia , a water shock wave is generated, just like a hammer blow, this is called a water hammer. The force generated by the reciprocating shock waves of water flow can sometimes be so great that it can damage water valves and pumps. When the electric water pump starts at full voltage, it can accelerate from a static state to the rated speed in less than 1 second, and the flow rate in the pipeline increases from zero to the rated flow rate. Since fluids have momentum and a certain degree of compressibility, rapid changes in flow will cause overpressure or underpressure in the pipeline, as well as "cavitation" phenomena. The impact of pressure will cause stress on the pipe wall and pwill make noise, just like a hammer hitting the pipe, called the “water hammer effect”. The water hammer effect is solely linked to the inertia of the water itself and has nothing to do with the water pump.

Dangers and elimination of the water hammer effect

Risks

The water hammer effect is extremely destructive: too high pressure will cause the rupture of the pipe, and vice versa. , too low pressure will cause the pipe to collapse and damage the valve and fixings. When the power is turned off and the pump is stopped, the potential energy of the pumping system will overcome the inertia of the motor and the system will stop abruptly, which will also cause pressure shock and surge effects. ram. In order to eliminate the serious consequences of the water hammer effect, a series of buffer measures and equipment are required in the pipeline.

Water hammer eliminator

The eliminatorr water hammer can effectively eliminate external water hammer and surges that can be generated by various types of fluids in the transmission system without blocking the flow of irregular fluids. the occurring water shock waves oscillate, eliminating destructive shock waves and achieving the protection purpose. There is an enclosed air chamber inside the water hammer eliminator, with a piston at the bottom end. When the shock wave enters the water hammer eliminator, the water shock wave acts on the piston and the piston moves towards the air chamber. The stroke of the piston movement is related to the gas pressure in the air chamber and the size of the water hammer wave. Under the double effect of the gas under a certain pressure and the irregular water hammer, the piston rises and falls to form a dynamic. balance, which effectively eliminates irregular shock waves from the EAu.

Using the water hammer effect

The water hammer pumping station is a pumping station that uses water hammer pressure to lift water. It is suitable for low-flow, high-head water supply in mountainous areas. . It is composed of a water hammer pump and corresponding. It is composed of hydraulic structures and is a new type of micro-hydraulic irrigation pumping station in mountainous areas. It is also generally called new micro-hydraulic station or hydraulic station. Water hammer pumping stations can be divided into two types: direct current water hammer pumping stations and alternating current water hammer pumping stations. At present, most of the water hammer pumping stations can be classified as water hammer pumping stationsdirect current ram. DC water hammer pumping station consists of micro-hydraulic source, inlet pool, electric water inlet steel pipe (long pipeline), pressure valve regulation, a DC water hammer pump, a water pump, a large storage tank, etc. DC water hammer pump is a hydraulic water hammer pump which directly uses the water hammer effect to exploit the water drop to lift the water. Its biggest feature is that it does not require special electric machine, fuel and electricity when suitable. head drop, pumping water can work continuously under certain conditions.

Water is likeHow does it turn into electricity?

In general, hydroelectric generation uses rivers with high water levels to flow to higher levels water to drive generators to produce electricityelectricity. This water can be used for irrigation after reaching the low water level..., and there is no waste. The water that flows towards the lower areas then evaporates through the natural environment, then under the effect of precipitation and snowfall... to then join the rivers located in the upper areas, thus continuing the cycle.

Water is converted into electrical energy using mechanical energy.

The process of converting water into electrical energy:

People use dams to increase the water level and the potential energy of the water

p>

Water flows from the dam As it flows up and down, potential energy is converted into kinetic energy. Because the potential energy is large, the kinetic energy converted to it is also large;

The kinetic energy carried away by the water causes the generator to convert it into the mechanical energy of the generator ;
