Hybrid power energy-saving type water evaporative condenser fan

Abstract

The invention relates to the technical field of fans, in particular to a hybrid power energy-saving type water evaporative condenser fan. Impact force of water flow is utilized to drive a water turbine enclosure to rotate, so that a connecting rod, a driven wheel and a cross fixed frame are driven to coaxially rotate, and fan blades are finally driven to rotate; when rotation speed of the fan blades reaches needed rotation speed, a motor is switched off, and power of the fan blades is provided by impact force of the water flow; when rotation speed of the fan blades does not reach needed rotation speed, the motor is started to drive the drive wheel to rotate, so that the driven wheel, the connecting rod and the cross fixed frame are driven to coaxially rotate, and the fan blades are finallydriven to rotate; a spiral shaft replaces a filler layer, so that gas inlet resistance of a gas inlet of the water evaporative condenser fan is reduced, air circulating effect is good, and the cooling effect is good. The hybrid power energy-saving type water evaporative condenser fan is simple and novel in structure, is good in air circulating effect, is good in cooling effect, has an electric-energy drive way and a water-energy drive way, which are flexible and practical, and can economically and conveniently reduce an energy consumption ratio.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to a hybrid energy-saving water-type evaporative condenser fan. Background technique [0002] For a long time, there have been two drive modes for water-type evaporative condenser fans. The first one is that the motor is directly connected or drives the fan through a reduction gear. Since the operating load of the water-type evaporative condenser is directly related to the meteorological conditions, the energy consumption ratio of the low-load state and the full-load state will not decrease; the second type is the high water pressure of the system pipe network to drive the water turbine , the water turbine coaxially drives the fan to run. The inlet water pressure of this type of water-type evaporative condenser is greater than 140kpa, which is 80kpa higher than that of the general water-type evaporative condenser. The evaporative condenser is small and cannot be used when the system...

Problems solved by technology

The inlet water pressure of this type of water-type evaporative condenser is greater than 140kpa, which is 80kpa higher than that of the general water-type evaporative condenser. The evaporative condenser is small and cannot be used when the system is overloaded

[0003] The force-bearing area of ​​the traditional water turbine blades is smaller than the impact area of ​​the water flow, and the utilization rate of the impact force of the water flow is low; and a filling layer is set under the fan, which increases the air intake resistance of the fan inlet of the water-type evaporative condenser , the air intake resistance is large, the air circulation effect is not good, and the cooling effect is poor
