The NLO Series Condensate Pumps Safeguard Energy Security with Cutting-Edge Technology
Driven by the dual carbon goals and the transfomaton of the energy structure, thermal/nuclear power plants have higher requirements for the efficiency.reliabiity, ant erosion pertormance and ease of maintenance of the core auxilay equpment As the heart of the condensate system the vertical mut stage tubular bagtype condensate pump has outstanding performance and is a standard core equipment for 15oOMW - 10oMW units. Our companys condensate pumps have introduced advanced foreign technologies and optimized them, reaching the international advanced level.
I. Core Positioning: High-efficiency "Pump" in Vacuum Conditions
The condensate pump s specifically designed for the high vacuumenvironmentof the condenser's hot wellat 0.095 - 0.1 MPa and the clean condensate water ondtion wth atemperature of s o°C. ts core function sto exracthe condensate water and increase rts pressure, The water s then sentto the deaeratorva alow presure heater, and at the same time, tprovides sealing water forthe shaftseal and the vacuum system. Itis a key equipment formaintaning the vacuum of the unitecoverng the working medium, and ensuring sate operation. Each unitis typicaly equipped with 2 pumps of 100% capacty (1 in operation and 1 on standby, and the frequency control is suitable for a load range of 50% 100%.
II. Technological Breakthrough: Six Advantages Leading the Industry
1. Anti-erosion Champion
Verical nstalation frst stage double suction mpeler low rotational speed veried water Inlecton hergh, NsHr as low as 3.5m completely soving the problem of vapor entrainment at the vacuum inlet.
2. Zero Leakage Sealing
Integrated mechanical seal condensate water sealing, zero air leakage, ensuring stable vacuum of the condenser.
3. Core Extraction Quick Repair
Without disassembling the outer cylinder and pipelines, the rotor, sea, and bearing can be extracted, reducing mantenance time by more than 50 %.
4. High Efficiency and Energy Saving
Space guide vanes optimize the hydraulic design, effciency of the milionunit model exceeds 85%, and annual electricity savings exceed mllions of kilowat-hours.
5. Stable and Reliable
Muitiple guide bearings support, elastic coupling, compact pump structure, good rotorigidity, can met diferent variable frequency operation conditions.
Anti-interlock, wear-resistant pump body sealing ring structure, ensuring operational reliability.
Self lubricating, high-maintenance-resistant titing pad sliding bearing structure,ensuring smooth operation of the pump, long maintenance cycle.
Integrated mechanical seal structure facilitates installation and maintenance.
Vibration < 4.5mm/s, MTBF reaches 25,000-32,000 hours.
6. More Space-Efficient
Vertical embedded installation, saving floor space, suitable for narrow machine rooms.
