Pump room automation system design Central pump room drainage centralized control system Direct sales pump room centralized control system
The automatic control system of the water pump station can remotely control the start and stop of the water pump, remotely monitor the operating status and operating parameters of the water source well, and fully meet all the functional requirements for unattended operation. It also adds automatic joint control of multiple wells, water potential and Functions such as water pump energy efficiency analysis have greatly improved the efficiency of water source well management and significantly reduced management costs. Surface water is generally collected and transported to water plants through water pumping stations. The water pumping station remote monitoring system is a subsystem of the urban water supply remote monitoring and dispatch management system. The dispatch center staff can remotely monitor the working conditions of the pumping station equipment. The water pumping station Managers can remotely control pumping station equipment.
The coal mine underground drainage remote automatic centralized control system is based on the actual conditions of the coal mine underground drainage system and pump room, combined with advanced PLC technology, to develop a set of automated control pump operation, collect on-site data, provide alarm information, and can be used in the production dispatch center A system that implements real-time monitoring. The system monitors the working status of various equipment in the underground drainage system through various advanced and reliable sensors, protection devices, electric actuators, etc., automatically starts and stops the operation of the water pump according to the water level in the water tank, and performs real-time monitoring of various status parameters during operation. Monitoring, while uploading data to the ground server through the interface. Realize automatic control of underground pump room drainage system. In an emergency, the entire pump room equipment can be remotely operated to eliminate the risk of water damage and truly realize the unattended pump room, making the pump room drainage system safe, reliable, energy-saving, efficient, economical and reasonable operation, thereby achieving the goals of reducing personnel, increasing efficiency, and safe production.
System functions
1. The ground dispatching room displays various operating parameters of the central pump room in real time and provides open monitoring configuration software. Users can draw various dynamic graphics and static graphics. The graphics screen has a link function and can easily switch to other screen displays.
2. The system operation mode is flexible and can be controlled on the ground, on-site, automatically and manually. In the automatic control mode, the system can automatically control the work of the water pump according to the water level in the water tank, and can also automatically drain water at a scheduled time according to the actual conditions of the mine to save the operating costs of the water pump. 3. The system sets a rotation work system to realize the cyclic starting and stopping of the water pump to prevent the motor from being damaged by the lake or other faults that are not discovered due to the standby pump or the maintenance pump not working for a long time, so as to achieve early detection and early treatment of faults. So as not to affect mine safety.
4. It has fault shielding function. If one of the operating pump, backup pump, and maintenance pump fails, the system can shield it and automatically switch to other water pumps for rotation. 5. According to the monitored water level signal, the low water level, high water level, upper limit water level signal and dangerous water level can be set. The pump will stop when the low water level is low, and the water pump will run when the high water level is high. The backup water pump will run at the same time when the upper water level is high; it will start when the dangerous water level is reached. Pumps all running. At the same time, the amount of water inflow is calculated based on changes in water level. When the amount of water inflow increases or changes suddenly, the water spring operation is started to reduce the occurrence of water inrush accidents.
6. The water pump system uses two methods of evacuation and water supply: jet pump and vacuum pump.
7. The system sets four water levels and corresponding operation modes: low limit water level, high limit water level, upper limit water level and dangerous water level.
8. When water level exceeds limit, switch failure, pressure drop, flow drop and other faults occur, the system will automatically stop running and prompt and alarm. 9. It has water inrush treatment function. The control system can monitor the flow rate of the open channel and the water level of the water tank. If the water inflow is too large or the water level change rate increases suddenly, the backup drainage pump and alarm prompt will be activated.
10. Can memorize fault status. When a certain part of the system fails, the system can implement a fault alarm and save the fault status. 11. The system can be seamlessly connected with the mine comprehensive dispatching system to realize data sharing.
12. Complete protection functions. It has over-temperature protection, flow protection, motor failure protection, electric gate valve failure protection and other functions.
13. The system has the control and switching functions of double sets of vacuum pump vacuuming and jet vacuuming devices.
Control system functions
Monitor the power supply current, power supply voltage, electric energy, line power supply status, etc. in the power distribution room of the water pumping station.
Monitor the working current, working voltage, maintenance status, start-stop status, protection status, etc. of each water pump.
Monitor the opening degree and open position and closed position status of each electric valve.
Monitor information such as outlet water pressure, outlet flow, water level in the intake tank, turbidity, etc.
Monitor the water level of the sewage pool in the pump room and control the drainage of the sewage pump according to the water level.
Automatically control each water pump and valve; remotely control each water pump and valve.
Automatically record the working time of each water pump, arrange the work of the water pump reasonably, and wear evenly. Monitor the vacuum degree of the suction tube and automatically and remotely control the vacuum pump
When personnel enter the pump room, the alarm will be automatically triggered, photos will be automatically taken and uploaded, and photos can also be controlled remotely. It will alarm when the current, voltage, water level, pressure, turbidity, etc. exceed the set value. It supports automatic protection and power outage alarm. Both monitoring terminals and monitoring center servers can store historical data
Automatically generate production reports and curves.
Supports multiple communication methods, and supports video surveillance when using optical fiber or wireless bridge communication.
