Abstract

The invention discloses an automatic temperature control device for a cooling fan on a cooling tower. The device comprises a water temperature sensing thermocouple and a feedback temperature controller, wherein the water temperature sensing thermocouple is arranged at a water outlet in a water tank of the cooling tower and on a mounting device on the wall of the cooling tower; the temperature controller is arranged at a power line inlet; the device is characterized in that: after the water temperature sensing thermocouple arranged in the cooling tower senses water temperature and the feedback temperature controller acquires a water temperature signal, the temperature controller controls a motor to start a relay to control the starting and the stopping of the motor; the water temperature sensing thermocouple is made of a PT100 platinum resistive material; the temperature controller is an XMTE200 temperature controller; and a shielding thermocouple line is used for line connection between the thermocouple and the temperature controller. Thus, the fan can be started stably relatively, and the starting and the stopping of the fan are not needed to be controlled according to temperature of cooling water, so the labor intensity is reduced, the control accuracy is improved, and the fan can be prevented from being frequently started or stopped.

Description

technical field [0001] The invention relates to an automatic temperature control device for a cooling fan on a cooling tower Background technique [0002] During the working process of the chiller, the cooling water of the cooler enters the cooling tower through the cooling circulation pump, and continues to enter the chiller for cooling cycle after cooling. [0003] With the continuous operation of the chiller, the temperature of the cooling water continues to rise. The cooling fan of the cooling tower adopts the direct start method and must be turned on and off under manual control. [0004] The defect of the control mode of the prior art: the outdoor temperature changes greatly in spring and autumn. It is easy for the cooling water temperature to be higher than the set cooling water temperature. This will cause the chiller to alarm and shut down, which will affect the normal operation of the chiller or the outlet water temperature will be lower than the set value. Co...
