Las bombas de vacío de dos etapas NASH TC ofrecen soluciones altamente fiables y eficientes para aplicaciones químicas y petroquímicas.
Los sistemas de extracción con condensador NASH son los sistemas de extracción de aire preferidos por las centrales eléctricas de ciclo de vapor de todo el mundo.
Ideal para una gran variedad de aplicaciones industriales, como la energética, y puede combinarse con eyectores o boosters para formar sistemas híbridos, permitiendo que haya niveles de vacío más altos.
Hogging: Initial evacuation of the condenser to a pressure of 200 to 400 mbar abs. (6" to 12" Hg abs.) within a defined period of time before applying steam to the condenser.
Holding: Continuous exhausting of the air leakage into the condenser during normal operation in order to optimize the efficiency of the power generation.
To realize a low absolute pressure, two stage liquid ring vacuum pumps are the perfect solution. They offer a low absolute pressure with a small and compact system design. Two stage vacuum pumps work best with water cooled condensers.
Capacity Bonus: You get more capacity and save energy when water vapor is condensed ahead of the NASH liquid ring vacuum pump. This performance bonus is made possible by NASH conical porting.
Power plants continue to struggle with the changing demand for electric power. When the plant runs at low load, ordinary liquid ring pumps are prone to damage from cavitation, resulting in higher operating costs and shorter pump life.
The upgraded line of NASH TC pumps offers an innovative, patent-pending design that extends pump life by reducing the potential for cavitation damage without affecting capacity or performance. The new design is available on all TC models, and as an aftermarket upgrade to existing NASH TC pumps. Aftermarket upgrades can be performed in any Nash factory service center. The upgraded pump design offers the same fit as your original NASH TC, with only minimal piping changes to your NASH system. External connections are unchanged.
