Electric cabinet manufacturers believe that there are many types of control cabinets, including electric control cabinets, frequency conversion control cabinets, low-voltage control cabinets, high-voltage control cabinets, pump control cabinets, power control cabinets, explosion-proof control cabinets, elevator controllers, PLC control cabinets, fire control cabinets, brick machine control cabinets, etc.
Electric cabinet manufacturers believe that there are many types of control cabinets, including electric control cabinets, frequency conversion control cabinets, low-voltage control cabinets, high-voltage control cabinets, pump control cabinets, power control cabinets, explosion-proof control cabinets, elevator controllers, PLC control cabinets, fire control cabinets, brick machine control cabinets, etc.
Electric cabinet manufacturers believe that the main structural features of the control cabinet:
1 advanced technology: the use of PLC equipment according to the water supply, fire requirements to achieve intelligent constant pressure variable water supply;
2. High-speed energy saving: electric cabinet manufacturers believe that the system can set the pressure according to the needs, and the system can automatically adjust the speed of the water pump and the number of running water pumps according to the set pressure, so that the equipment can run in a good state of high-speed energy saving;
3. Stable water supply pressure: the system realizes closed-loop control, which can automatically adjust the difference between the set pressure and the system pressure to keep the pressure constant;
4. Stable operation: The electric cabinet manufacturer believes that the system is automatically controlled by a frequency converter or a frequency converter plus an intelligent controller, and the operation is very simple;
5. Extend the life of the motor and water pump: The cabinet manufacturer believes that all pumps are soft-started, eliminating the impact current when starting. Each pump cycle start, so that the standby pump will not rust or wear due to long-term use or frequent use. Conduct regular fire inspection;
6. Perfect protection function: with short circuit, overcurrent, overvoltage, overheating, overload and other protection. If there is a fault in the operation of the water pump, it will automatically stop working and send out an alarm output; the system has the functions of self-check, fault judgment, fault memory, fault display, automatic start of the standby pump and so on.
7. Low-flow sleep function: The electric cabinet manufacturer believes that it can be equipped with an auxiliary small pump, which can automatically shut down the main pump and open the auxiliary small pump under the condition of system operation at night or other low-flow conditions to avoid waste caused by opening the high-power water pump;
8. Easy operation function: the programming setting of frequency converter and controller is convenient, simple and easy to master;
9. Manual automatic switching function: equipped with manual switch control, can ensure the safe and continuous operation of the equipment;
10. With partial pressure time-sharing water supply function, can control six periods of time. Electric cabinet manufacturers believe that users can set their own, can achieve unattended.
Electric cabinet manufacturers believe that the PLC integrated control cabinet has protection functions such as overload, short circuit and phase loss protection. Compact structure, stable work and complete functions. It can be combined according to the actual control specification, which can realize the automatic control of a single cabinet, or realize the distributed control (DSC) system composed of multiple cabinets through industrial Ethernet or industrial field bus network. Electric cabinet manufacturers believe that PLC control cabinets can be adapted to various industrial automation control occasions. Widely used in electric power, metallurgy, chemical industry, papermaking, environmental protection sewage treatment and other industries. PLC control cabinet is the core and soul of modern industry. It can complete equipment automation and process automation control, and realize the characteristics of perfect network function, strong anti-interference ability, stable performance and strong scalability.
