Description

Technical Field

[0001] The utility model belongs to the field of sewage treatment station equipment in coal mines, and in particular relates to a system for replacing a water pump motor in a sewage treatment station in a coal mine. Background Art

[0002] The pump motor is a key piece of equipment in coal mine wastewater treatment plants. It converts electrical energy into mechanical energy. Its operating principle is that electrical energy input to the motor drives the motor's rotor, which in turn drives the pump, allowing wastewater to flow through the plant according to a set flow pattern for subsequent treatment. Due to aging equipment, performance degradation, frequent failures, high energy consumption, safety hazards, and the need for renovation, the pump motor in the wastewater treatment plant needs to be replaced to ensure normal operation and improve overall efficiency.

[0003] For safety reasons, the water pump motor in the underground tunnel is generally installed on a step three meters above the ground. The motor weighs 500 kilograms. When replacing the water pump motor, it is entirely dependent on manpower to remove the old water pump motor and transport it away, and then transport the new water pump motor to the front and lift it up the steps, which is time-consuming and labor-intensive. Moreover, the steps are often recessed into the side walls of the tunnel, affecting the transportation process. It is also unsafe for workers to operate, and there is a risk of injury if they operate carelessly. Utility Model Content
