Hello, do you want to ask what are the precautions for cleaning the turbine of marine generator? Precautions for cleaning marine generator turbines are:
1. Pay attention to the impact of moisture in the cleaning room on the lines.
2. Be careful not to break the line when cleaning.
3. When cleaning the marine generator turbine, pay attention to power outages. The above are the precautions for cleaning the marine generator turbine.
Also known as turbine and turbine. Turbine is the transliteration of English turbine, derived from the Latin word turbo, which means rotating object. The working conditions and working fluids of turbines are different, so their structures are diverse, but the basic working principles are similar. The most important component of the turbine is the rotating element (rotor or impeller), which is installed on the turbine shaft and has blades evenly arranged along the circumference. The energy of the fluid is converted into kinetic energy when it passes through the nozzle during the flow. When it flows through the rotor, the fluid impacts the blades, pushing the rotor to rotate, thereby driving the turbine shaft to rotate. The turbine shaft drives other machinery directly or through a transmission mechanism to output mechanical power. Turbines can be divided into water turbines (used as the power source of hydropower stations), steam turbines (used in thermal power plants, ship propulsion, etc.), and gas turbines (used as the propulsion power of jet aircraft, ships, etc.) according to the different working fluids used. power, as well as power plants, small power stations for peak loads, etc.) and air turbines (can only be used for small power), etc.
Hydraulic turbine--When water flows from a high-water level reservoir along a channel to a hydraulic turbine at a low water level, the potential energy of the high-water level water turns into kinetic energy, which drives the turbine to rotate. The tailwater flowing through the turbine flows along the waterway. The only purpose of modern water turbines is as a power source for hydropower stations, driving generators to generate electricity.
Steam turbine-its working fluid is steam, which has thermal energy. Steam comes from boilers burning fossil fuels or from steam generators heated by nuclear power plants. The high-temperature and high-pressure steam they generate is sent to the steam turbine through the nozzle at high speed, driving the rotor to rotate and output power. The steam flow rate is very high and the turbine rotor size is small, so the speed can reach 10,000 rpm. Steam turbines are mainly used in thermal power plants to drive generators to generate electricity; they are also used in large ocean-going ships and submarines as main engines to drive propellers and propel ships.
Gas turbine--it, together with the compressor and combustion chamber, becomes the three main components of the gas turbine device. Air is supplied to the compressor and compressed into compressed air of higher pressure and temperature. It flows into the combustion chamber to mix and burn with fuel, forming a high-temperature, high-pressure, and high-speed gas flow. It flows into the gas turbine and drives the gas turbine to rotate. The shaft outputs mechanical power. The speed of the gas turbine reaches tens of thousands of revolutions per minute. The most widely used modern gas turbine is as the propulsion power of jet aircraft. Some are used as ship power, power plants, small power stations for peak loads, and as the power of gas pumps for transporting natural gas over long distances. Gas turbines used to power locomotives and automobiles are still under development and testing.
There is also a gas turbine used in rocket engines. It serves as the power for a delivery pump that pressurizes rocket propellant (fuel and oxidizer). It is powered by a gas generator.The required high-temperature gas is produced by chemical action, which blows the turbine to rotate and drives the delivery pump to operate.
In addition, there are also turbines that use compressed air as the working medium to push the rotation of the turbine, which can only be used as a small power. This type of turbine is called an air turbine.
