GZ series evaporative cooling pump
Quick Details
The optimal hydraulic model is used for impeller, the pump is of an utmost dynamic-static balance and reliable performance.
The pump shaft is an extended one from the motor, so the concentricityh is absolutely reliable.
The pump which is supported by well-known international brands’ bearing, runs at little vibration and low noise.
Singl-stage single-suction horizontal centrifugal pump; closed impeller and volute chamber are adopted.
Coaxial volute structure, high efficiency, small volume, light weight, easy installation and maintenance.
Mechanical seal, no damage to shaft, no leakage, long perfomance life.
No overload: when pump operate on the any point of the performance curve, the comsumed power of the pump will not exceed the rated power.
Application
GZ series evaporative cooling pump is special applied on the evaporative condenser, it also can be used in some large flow and low head location.
Evaporative condenser priciple
Evaporative condenser is utilizing sprayed water part outside the coil pipe to absorb the heat of high temperature gaseous refrigerant inside coil pipe through evaporation to cool refrigerant inside the pipe gradually from gaseous state to liquid state.
Sprayed water is conveyed by water pump from collecting tank to spraying pipe on top of evaporative condenser, and sprayed by the nozzle to exterior surface of condensing reed pipe to form a very thin water film, part water of which will be evaporated to vapor after heat absorption, the rest will fall to collecting tank for recycled use of water pump.
Axial-flow fan forces the air to be absorbed into and flow through coil pipe from the top and side wall, whereas hot wet air of feeding and saturate hot wet air are exhausted to ambient atmosphere, part water drops included in hot wet air are retained by water collector, for effective loss control of water drop scattering, thus scattering rate of vapor is less than 0.001%, vapor scattered and lost in atmosphere will be complemented through control of ball float valve in the system.
