Centrifugal fan intelligent cooling protection self-starting control system

Abstract

The invention discloses a centrifugal fan intelligent cooling protection self-starting control system. The system comprises a centrifugal fan, a cooling structure, a temperature sensor, a controller, a display control panel, an alarm unit, a power supply and a cooling water tank, wherein the cooling structure and the temperature sensor are arranged on the centrifugal fan; the controller is connected with the centrifugal fan; the display control panel and the alarm unit are arranged on the controller; the power supply is connected with the controller; the cooling water tank is connected with the cooling structure through a cooling driving device; the temperature sensor is further connected with the controller; the cooling driving device is also connected with the power supply and the controller; the cooling driving device is a temperature control starting circuit provided with a cooling water pump; and the power input end of the temperature control starting circuit is connected with the power supply. The centrifugal fan intelligent cooling protection self-starting control system provided by the invention can automatically cool equipment at a high temperature during equipment operation and can give an alarm in time when the temperature exceeds a set value to remind related staff to maintain the equipment.

Description

technical field [0001] The invention belongs to the field of centrifugal fan use safety, and specifically refers to an intelligent cooling protection self-starting control system for a centrifugal fan. Background technique [0002] The centrifugal fan is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas. It is a driven fluid machine. Centrifugal fans are widely used in ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and induction of boilers and industrial furnaces; cooling and cooling of air conditioning equipment and household appliances Ventilation; drying and selection of grain; wind tunnel wind source and inflation and propulsion of hovercraft, etc. With the advancement of my country's industrialization process, the industrial sector is vigorously carrying out energy conservation and consumption reduction, industrial upgrading and integrat...

AI Technical Summary

Problems solved by technology

[0004] Existing centrifugal fans will generate higher temperatures when in use, especially in the process of discharging certain high-temperature gases, which are prone to overheating, and when the centrifugal fan is in a high-heat environment for a long time, it will It greatly reduces its service life, and it is easy to cause various internal parts to be damaged to varying degrees, which brings a lot of potential safety hazards to the normal use of the equipment.
