External valve water cooling system cooling tower of fan motor

Abstract

An external valve water cooling system cooling tower of a fan motor comprises a tower body, a fan cover is arranged at the top of the tower body, a fan is arranged in the fan cover, a rotary shaft of the fan is connected with a fixed plate, the fixed plate is connected with the outer wall of the tower body, a second rotary wheel is arranged on the rotary shaft, a motor is arranged on the outer portion of the tower body, a first rotary wheel is arranged on an output shaft of the motor, a through groove is formed in the tower wall of the tower body, and a belt is arranged between the first rotary wheel and the second rotary wheel and penetrates through the through groove. The fan motor is moved to outer portion of the cooling tower, and is completely isolated from moisture and humidity inside the tower, the motor works normally, and the motor is completely prevented from being damped.

Description

technical field [0001] The invention relates to a power tool, in particular to a cooling tower of a water-cooling system with an external valve for a fan motor. Background technique [0002] The cooling tower is the core equipment for cooling the cooling water of the converter valve of the DC converter station. Whether the cooling tower operates safely and stably directly affects the heat dissipation and cooling of the cooling water. During the operation, the inner wall of the cooling tower is in direct contact with water. Due to the poor corrosion resistance of the material, the inner wall is extensively corroded; the fan motor is inside the cooling tower, and the fan bearing needs to be oiled online for maintenance in the cooling tower. It is exposed to water vapor and moisture all the year round. Wiring And the rapid deterioration of the insulation performance of the main body causes the failure of the fan. The replacement requires a lot of manpower and material resources...

Problems solved by technology

During the operation, the inner wall of the cooling tower is in direct contact with water. Due to the poor corrosion resistance of the material, the inner wall is extensively corroded; the fan motor is inside the cooling tower, and the fan bearing needs to be oiled online for maintenance in the cooling tower. It is exposed to water vapor and moisture all the year round. Wiring And the rapid deterioration of the insulation performance of the main body causes the failure of the fan. The replacement requires a lot of manpower and material resources, which is time-consuming and labor-intensive. It has always been a key problem for maintenance personnel.
