The remote control part and control core of the stainless steel gear pump use high-performance programmable controllers. The detection part is divided into two parts: one is the analog quantity detection part. It is mainly used to detect the water level of the water tank. The second is the switch quantity detection part. Connect the switching signal such as the vacuum circuit breaker status, the working status and the opening and closing position of the electric valve in the high-voltage start cabinet to the PLC, and the system running status can be detected.
1\System requirements
The system and equipment meet the requirements of relevant standards and coal industry standards.
2\System composition
(1) System composition
(2) Control subsystem
The system consists of PLC\touch screen\detection part\execution part etc.
(3) Ground remote control terminal
The industrial control configuration software used in the ground remote control terminal control software can monitor the operating parameters of the stainless steel gear pump system in real time, and can remotely control the start and stop of the stainless steel gear pump system.
The control performance and method automatically start/stop the operation of the stainless steel gear pump according to the water level of the sump, real-time monitoring of various status parameters in operation, and upload the data to the ground control room through the interface.
According to the monitored water level signal, low water level\operating water level and 3 upper limit water level signals and dangerous water level can be set. The pump stops when the water level is low; the stainless steel gear pump runs when the water level is high; and the spare stainless steel gear pump is put into operation according to the upper limit water level. Run at the same time; start the stainless steel gear pump when the water level is dangerous. At the same time, calculate the water inflow according to the water level change. When the water inflow increases or change suddenly, start the stainless steel gear pump to reduce the occurrence of water inrush accidents.
Each stainless steel gear pump can be set with four working modes: "local control"\"semi-automatic control"\"automatic control" and "maintenance mode", which can be set directly on the controller.
Stainless steel gear pump system adopts vacuum pump or jet method to vacuum:
The system starts the corresponding equipment for vacuuming according to the water level status or the operator's command.
When the vacuum pressure reaches the requirement, the stainless steel gear pump motor will be automatically started, and then the electric gate valve of the stainless steel gear pump outlet line will be opened for drainage.
If the pressure of the stainless steel gear pump does not reach the set value within the time after the electric gate valve is opened, the system will automatically stop the operation of the stainless steel gear pump and close the electric gate valve and alarm at the same time.
