Assembled explosive-proof and intrinsic safety type control box KXJZ-1140 (660) for mines
2、Assembled explosive-proof and intrinsic safety type control box KXJZ-1140 (660) for mines
The programmable control box is controlled by Siemens original PLC, equipped with a high-definition touch screen, which can control the start/stop of permanent magnet motors, frequency converters, water-cooled motors and cooling fans (internally integrated water-cooled motors supporting electromagnetic starter function), acquisition and receiving belt type Protect sensors, disc brakes, and tensioning equipment signals along the conveyor, and automatically adjust the operating speed of the belt conveyor according to load conditions (load detection equipment is required). The control box reserves Ethernet and RS485 communication interfaces, which can transmit data with the frequency converter, integrated protection system, and integrated automation system.
It can be used as the main control system of belt conveyor.
The touch screen displays the operating status of the belt conveyor in real time, mainly including the following screens:
Ø Main monitoring screen
The operation overview of the belt conveyor, including the main motor current, speed, motor temperature, and monitoring of the operation of each auxiliary motor;
Ø Fault alarm screen
Real-time display of the fault and alarm information of each device of the belt conveyor to help customers quickly locate the point of failure, and timely analyze and deal with various software and hardware faults during operation;
Ø Parameter setting screen
According to the requirements of the on-site working conditions, timely modify the belt conveyor system parameters to meet the normal production conditions;
Ø Trend curve screen
The current and temperature curves of the belt conveyor motor are displayed in the form of trend graph;
Ø Other screens required by customers
The control box contains manual, automatic, remote, and on-site working methods, which can meet the needs of use under various working conditions on site;
The control box supports multiple communication protocols such as Ethernet and RS485, and can communicate with the frequency converter, main control system, comprehensive protection system, and comprehensive automation system to reduce field wiring and reduce customer maintenance;
The HMI configuration screen adopts humanized design and parameterized design. Customers can adjust the operating characteristics of the system by changing the parameter settings of the touch screen to meet the needs of various production conditions;
The internal hardware design of the control box adopts a new modular component design, which is convenient for on-site replacement of accessories and minimizes downtime;
According to site conditions, control the start/stop of the belt conveyor in the conveyor system, and automatically adjust the operating speed of the belt conveyor according to the load condition;
Scope of application
It can be used in the PVD control system of belt conveyor in explosion-proof occasions, the centralized control system of belt conveyor in explosion-proof occasions, and the intelligent control system of belt conveyor in explosion-proof occasions.
