TECHNICAL PARAMETERS
Fangnuo's cooling tower spray water pump:
Special spray water pump, brand: Kaiquan;
Motor: Fully-sealed external fan seal cooling motor, protection level IP55, insulation level F, temperature rise level B, power supply 380V × 3 phase × 50HZ, branded by Kaiquan (Lu'an Motor). If there are additional requirements for the brand and form of the motor, it is non-standard.
Cooling tower spray water pump type:
(1) Classification by structure
Centrifugal pump (most commonly used): large flow, moderate head, high efficiency, suitable for most industrial cooling towers;
Axial flow pump Extra large flow: low head, suitable for large open cooling towers;
(2) Classified by drive method
Fixed-speed pump: simple structure, high energy consumption, suitable for small cooling towers or constant loads;
Frequency inverter pump: energy saving (adjustable flow), adapt to variable load, frequency inverter cooling tower, energy-saving transformation;
(3) Classification by material
Cast iron pump: low cost, resistant to general water quality, suitable for ordinary industrial water use;
Stainless steel pump (304/316): corrosion resistant, long life, long life, suitable for seawater, chemical, and high chlorine environments;、
Plastic pump (PP/PVDF): resistant to acid and alkali, lightweight, suitable for corrosive media such as electroplating and pickling;
Dimensions for measuring the quality of the cooling tower spray water pump:
Performance: flow, head, efficiency;
Operating status: fault cycle, vibration and noise, whether it is leaked, temperature rise, start and stop;
Economics: initial cost, life cycle cost, warranty and service;
When choosing a cooling tower spray water pump, you need to comprehensively consider the system requirements, pump performance parameters, operating environment, energy efficiency and economics.
