Mine drainage monitoring system

The underground pump is one of the main equipment in coal mine production. The remote control and monitoring of the underground pump house is an important part of the comprehensive automation construction. At present, in the drainage system design of the mine pump house, a number of multistage centrifugal pumps are generally set up, one is used, one is prepared and one is repaired. These pumps have high voltage, high power and complex operating conditions, and it is difficult to achieve real-time monitoring manually. The underground drainage monitoring system of coal mine takes the programmable controller as the control core, and monitors the working state of each equipment of the underground drainage system through various advanced and reliable sensors, protection devices and electric actuators, so as to realize the automatic control of the underground pump drainage system. The system integrates computer technology and automatic control technology, and is applied to the full automation of underground drainage in coal mine and remote monitoring of the ground. According to the actual situation of the mine, automatic transformation can be carried out on the basis of the original facilities, so that the equipment can automatically run and self-diagnose in the case of no interference. At the same time, through the intelligent scheduling algorithm according to the water level of the water tank, the running time of the water pump, the coal mine power load and other information, all the pumps in the pump room are centralized management and unified scheduling, so that each pump can be balanced use and achieve the best working state, effectively extend the service life of the unit on the basis of energy saving and emission reduction, and increase the efficiency basis. Further reduce the labor intensity of staff, and improve the intelligent level and operation management level of coal mines on the basis of safe production.

DESCRIPTION

Product use

The underground pump is one of the main equipment in coal mine production. The remote control and monitoring of the underground pump house is an important part of the comprehensive automation construction. At present, in the drainage system design of the mine pump house, a number of multistage centrifugal pumps are generally set up, one is used, one is prepared and one is repaired. These pumps have high voltage, high power and complex operating conditions, and it is difficult to achieve real-time monitoring manually. The underground drainage monitoring system of coal mine takes the programmable controller as the control core, and monitors the working state of each equipment of the underground drainage system through various advanced and reliable sensors, protection devices and electric actuators, so as to realize the automatic control of the underground pump drainage system. The system integrates computer technology and automatic control technology, and is applied to the full automation of underground drainage in coal mine and remote monitoring of the ground.

Product use

 

Main feature

The system has the advantages of high reliability, real time, high information degree, good security measures, strong anti-interference ability, low failure rate, easy management and maintenance;

The system realizes the network monitoring and control of all the equipment in the pump room of the underground drainage system in the safety production command and dispatch center, so that the pump room is unattended and the equipment runs safely and reliably.

The system control has four working modes: automatic, semi-automatic, manual and maintenance.

Multiple pumps in the pump room can share a PLC control box, easy connection; Each pump can also be configured with a PLC control box, redundant design;

The system consists of automatic data acquisition, automatic control, automatic rotation work, dynamic display, fault record alarm and communication interface.

The system can automatically start and stop the pump according to the water level of the sump, predict the growth rate of the water level, and automatically choose the drainage in the normal season of electricity consumption;

According to the monitored water level signal, low water level, high water level and. Upper water level signal and dangerous water level; Stop pumping at low water level; Pump operation at high water level;

At the upper water level, the standby pump runs simultaneously; When the water level is dangerous, start the pump to run all;

With powerful data processing and collection functions, it can detect the water level of the water tank, outlet pressure, pipeline flow, pump body temperature, vibration, current, running time, equipment status and other parameters in real time.

With a variety of protection and voice alarm functions, when there is a pump failure, pump body overheating, pressure drop, low current, low flow, etc., the system will automatically stop running and issue a voice alarm;

It can use animation, graphics, Chinese characters and other ways to visually display the running state of the pump, system working parameters, equipment failure state, etc. With alarm record, operation record, operation record, power record, historical data, historical curve and other query functions;

Curve display: the system has real-time curve display of water level, flow, pressure and other analog quantities;

Equipment maintenance time setting: the platform can set the equipment maintenance and maintenance time at will, and automatically remind the expiration;

The drainage system has automatic water injection link, gate valve control link, water level automatic monitoring link, fault protection link, motor automatic control link, peak automatic operation and other functional links;

The system software is rich in functions, which can achieve unattended, peak avoidance, valley filling and efficiency analysis, and help the mine to reduce staff, save energy and improve efficiency. It can realize functions such as cloud monitoring and mobile APP.
