Abstract

The invention discloses a constant-pressure wind supply electric control system of an air blower and an electric control method of the constant-pressure wind supply electric control system. The electric control system comprises a wind pressure transmitter, an SFD (Single Frequency Dialing) signal isolator, an intelligent PID (Proportion Integration Differentiation) adjuster, a switching power supply device, a change-over switch, an electromagnetic relay and a variable frequency starting switch; the wind pressure transmitter is mounted in a wind supply pipe of the air blower; the SFD signal isolator, the intelligent PID adjuster, the switching power supply device, the change-over switch and the electromagnetic relay are integrated and mounted in a distribution box through an electric control circuit. According to the constant-pressure wind supply electric control system of the air blower, after online intelligent initiative sensing, automatic analysis and rapid processing are carried out according to the size of wind quantity, a signal is transmitted to a Roots air blower frequency converter; the frequency converter is used for adjusting the level of frequency according to the intensity of an input signal and the system is used for supplying wind under a constant-pressure state.

Description

technical field [0001] The invention relates to the technical field of Roots blower wind supply electric control, in particular to an electric control system and an electric control method for a blower constant pressure wind supply. Background technique [0002] The Roots blower supplies air to the flotation cell in the flotation system. The air volume needs to be adjusted according to the change of the raw ore grade. The air supply valve installed on the flotation cell is completed. When the air supply valve is adjusted to a small air volume , the wind pressure of the Roots blower will increase, and the Roots blower operates under high wind pressure, suffocation and overload industrial and mining conditions. Long-term continuous overload operation will burn out the main motor of the blower, and the failure of the main motor will cause the beneficiation system to stop production. Contents of the invention [0003] The purpose of the present invention is to provide a blower...
