Problems solved by technology

The main disadvantages are that the reliability of the water pump start is poor, the cavitation is serious when the water pump starts to drain, the artificial intelligence of the electric gate valve is low, and when the water volume and level of the drainage pipeline are low, the start of the water pump will easily cause the motor to start a large current, which will cause the motor to burn or the circuit to trip. When the system is powered off, the water pump system has poor water hammer effect, which may easily cause water hammer accidents

Abstract

The invention relates to an automatic control device for a mine water pump. A water inlet pipe of the water pump communicates with a bottom valve at the bottom of a water sump in a sealed mode, and a hydraulic-control combined valve is connected to a water outlet pipe of the water pump in a sealed mode in series. A water level controller is arranged in the water sump and is in signal connection with a programmable control switch. A deflation overflow signal valve is arranged on the water pump and is in signal connection with the programmable control switch. The automatic control device for the mine water pump is simple in structure, safe, reliable and high in automation degree.

Description

technical field [0001] The invention relates to a water pump automatic control device, in particular to a mine water pump automatic control device. Background technique [0002] The existing mine water pump automation control device is mainly composed of electric gate valve, vacuum device, water level, pressure, flow and other sensors, PLC programming software and hardware control device, server and cables. The main disadvantages are that the reliability of the water pump start is poor, the cavitation is serious when the water pump starts to drain, the artificial intelligence of the electric gate valve is low, and when the water volume and level of the drainage pipeline are low, the start of the water pump will easily cause the motor to start a large current, which will cause the motor to burn or the circuit to trip. When the system is powered off, the water pump system has poor water hammer effect, which may easily cause water hammer accidents. Contents of the invention ...
