Remote control system of underground pump station

Abstract

The invention discloses a remote control system of an underground pump station, The remote control system is used for controlling the interlocking control of underground pump station equipment and anelectric valve, automatic adjustment and control of ore pulp conveying and waste water discharging are realized, the automation of a production system is improved, the labor intensity of workers is reduced, and meanwhile, the operation stability and operation efficiency of the equipment are improved; and the system specifically has the beneficial effects that the operation condition of an ore pulpconveying pump is automatically judged by the system, an alarm signal if given out when a fault is encountered, and a standby pump is automatically started; according to multiple parameters such as the temperature, the vibration, a pipeline flow, the running state of the ore pulp conveying pump is judged, and starting and stopping of the ore pulp conveying pump are controlled according to the comprehensive conditions. According to the system, the operation process is simple, and the system is suitable for modern management.

Description

technical field [0001] The invention relates to a remote automatic control technology of a pump station, in particular to a remote control system for automatic alarm and automatic start and stop of a large-flow, high-lift underground pump station. Background technique [0002] Pumping stations are widely used for the transfer of liquid and slurry transportation, while underground pumping stations are generally used for slurry transportation with large flow and high head. Take a mine production unit as an example: beneficiation is to enrich the useful minerals in the mined ore, and the output concentrate accounts for about 13-15% of the total processing volume, which is sent to smelting. 85-87% of the tailings produced are dehydrated and sent to the tailings pond for storage. The underground pump station is the transfer station before the tailings are dewatered. Due to the need for self-flow of ore pulp, the height difference between the beneficiation process and the underg...

AI Technical Summary

Problems solved by technology

The control of slurry transportation is limited to the start and stop of the slurry delivery pump. Although it has a soft start control function, due to the lack of monitoring of conditions and parameters such as liquid level, flow rate, and pump speed, every time there is a equipment failure or a change in the slurry flow rate Manual adjustment and operation are required by workers. If it is not found in time, the tailings slurry will not be transported in time, and the underground pump pool will overflow. For large-flow slurry transfer, it may cause the underground pump station to be submerged within 3-5 minutes, resulting in a major production accident. It will also cause the upstream process to stop production

[0003] To sum up, the control of the original underground pumping station has the following problems: First, the design of the existing power distribution and control mechanism is backward, which only displays the equipment start, stop, operation signal and operating current, and lacks the monitoring of the signal of the slurry pump and the delivery of the slurry The protection of the pump; the second is that the operation management of the current control system is not interlocked with the measurement value of the slurry delivery pump and the liquid level of the sewage pump pool, and manual operation is still used. The operation process is cumbersome and the degree of automation is low, which is not suitable for modern enterprises. management; the third is that the current control operation and protection signals do not enter the main control room for tailings transportation, and the start and stop of the equipment does not have a self-start function, which increases the labor intensity of the employees
