The requirements of the power generation industry for vacuum systems are concentrated on high efficiency, stability, and long-cycle operation. Condenser vacuum degree directly affects steam turbine thermal efficiency, turbine oil purification is related to unit lubrication safety, and hydrogen replacement involves explosion-proof safety. Traditional vacuum pumps are prone to issues such as pumping capacity attenuation, high energy consumption, and frequent maintenance under high-temperature, high-humidity, and dusty conditions in power plants. Leynow provides vacuum pump and vacuum unit solutions targeting power generation industry conditions, and they have been widely used in multiple key processes of thermal power, nuclear power, biomass power generation, and new energy power stations.
Challenges Faced by the Industry
The requirements of power generation production for vacuum systems are not just about "pulling a vacuum", but more importantly, high efficiency, stability, and long-cycle operation. In practical applications, customers often encounter the following types of problems:
Vacuum Degree Attenuation Affects Thermal Efficiency
A decrease in condenser vacuum degree will directly raise the steam turbine exhaust pressure, reduce unit thermal efficiency, and increase coal consumption.
Poor Adaptability to High-Temperature and High-Humidity Conditions
Power plant environments have high temperature, high humidity, and high dust content. Ordinary vacuum pumps experience decreased pumping capacity and increased failure rates.
High Safety Requirements for Hydrogen Replacement
The generator hydrogen cooling system has extremely high requirements for the safety and reliability of vacuum equipment during the replacement and drying processes.
Maintenance Costs and Downtime Losses
Vacuum pump oil needs to be replaced regularly. Unplanned downtime for maintenance directly affects power generation, and maintenance costs add up.
Leynow Power Generation Industry Solutions
Targeting the actual working conditions of the power generation industry, Leynow provides overall vacuum solutions centered on vacuum pumps and vacuum units, forming a complete service closed loop from equipment selection and installation and commissioning to post-maintenance.
