Abstract

The invention relates to a remote drainage control system of a centrifugal pump. The system comprises a soft start cabinet and at least one centrifugal pump drainage device which are arranged at a drainage site end, at least one centrifugal pump start-stop circuit is arranged in the soft start cabinet, and the centrifugal pump drainage devices and the centrifugal pump start-stop circuits are the same in number and are in one-to-one correspondence; a remote control device arranged at a remote end is further included; any centrifugal pump drainage device comprises an electric drainage valve, a centrifugal pump, a water pump motor and a drainage pipeline; and the water outlet end of the centrifugal pump communicates with the drainage pipelines, the electric drainage valves are arranged on the drainage pipelines, and output shafts of the water pump motors are in transmission connection with the centrifugal pump. The water pump motors are electrically connected with the corresponding centrifugal pump start-stop circuits; and all the electric drainage valves, all the water pump motors and all the centrifugal pump start-stop circuits are electrically connected with the remote control device. Start and stop control can be conducted on drainage of the multi-stage centrifugal pump at the remote end, a water pump worker does not need to monitor operation on site, and the labor cost is low.

Description

technical field [0001] The invention relates to the technical field of well drainage, in particular to a remote drainage control system for a centrifugal pump. Background technique [0002] During the construction of prospecting shaft to level roadway, to prevent water gushing in the roadway, a temporary drainage system needs to be built. Usually, a cavern is excavated at a reasonable position in the main roadway as a temporary water tank. The water gushing from the roadway flows to the sedimentation tank in front of the water tank through the roadway ditch. Stage horizontal centrifugal pump discharges to the surface. [0003] Due to the limitation of construction site conditions, the temporary drainage system of some mines usually uses a single soft starter cabinet to control multi-stage horizontal centrifugal pumps to drain water. When the pump is started, the power required by the pump is the smallest when the flow rate is zero. Therefore, the drain gate valve should be...
