| description | The invention belongs to the technical field of coal mine safety, and particularly relates to an intelligent variable-frequency water injection pump and method for mine pulsating water injection. The intelligent variable-frequency water injection pump is provided with an anti-explosion variable-frequency motor, a piston in the high-pressure pump is driven to move through transmission of the anti-explosion variable-frequency motor so as to form high-pressure water, the variable-frequency control equipment comprises a variable-frequency control cabinet and an operation table, and an intelligent electric control system is installed in the operation table. Output signals of the frequency conversion control cabinet are adjusted through the operation table so as to change the output power of the anti-explosion frequency conversion motor, and then frequency conversion of water outlet pressure and flow of the high-pressure pump is achieved. According to the method, pre-designed variable-frequency pulsating water inje |
