CCCF fire patrol control cabinet
CCCF fire patrol control cabinet -- Product Overview
CCCF fire inspection cabinet is solid and beautiful, and electrical components are selected from international and domestic famous brand products. According to different use needs, the products have the functions of main circuit, open phase, overload protection, pump body leakage, stator winding overthermal protection and so on. All main and standby control products shall have the function of automatic stop of fault pump and delayed automatic switching of standby pump.
This product aims at this phenomenon. According to the industry specification of automatic fire water supply equipment formulated by the Ministry of public security, jjk-f-xj digital intelligent fire patrol controller meeting the specification requirements is used in the control equipment to form a special control equipment for fire water supply, and the automatic low-frequency patrol function is added.
CCCF fire patrol control cabinet -- product performance
PLC programmable controller is used to automate the motor pump and related equipment. It can carry out regular automatic patrol inspection of fire pump, solve the problem of fire pump seizure, frequency conversion pump cutting, eliminate water hammer effect, alarm and joint control of fire control center.
Jjk series water pump control cabinet mainly uses the special monitoring software of Mitsubishi PLC to save the trouble of bus and computer networking through RS-232 / RS-485 and wireless connector. The operator can know the working conditions and various technical parameters of outdoor pump unit and other equipment only by operating the computer in the control center, and can automatically make correction control according to real-time needs, Make it possible for the computer room to be unattended, so as to achieve the purpose of man-machine interface.
CCCF fire patrol control cabinet -- intelligent control
Microcomputer intelligent control is successfully developed by our technicians on the basis of variable frequency speed regulation control cabinet in order to meet the market requirements. PLC programmable controller is adopted to carry out man-machine interface for pump unit and other equipment, supplemented by computer technology for intelligent control. It has the functions of automatic, manual, remote operation, computer joint control, etc. With advanced control methods, reliable electrical performance, convenient network connection, greatly reducing operation cost and more obvious energy-saving effect, it is a new modern intelligent control product with high quality and low price.
CCCF fire patrol control cabinet - Instructions
1. When installing the wiring, it must be connected in strict accordance with the schematic diagram of terminal blocks at the letter symbol level. After completion of the connection, carefully check whether the wiring is wrong, and then check whether the actual capacity of the controlled motor is consistent with the capacity controlled by the product. If not, refer to the data listed in each parameter table to reset the current, current action value and protection delay setting value of time conversion device, and thermal relay setting value.
2. Manual operation: when the power is supplied, the power indicator light is on, turn the function switch to the manual position, turn on the control switch of each sub pump (the switch corresponds to each group of water pumps), turn the water pump operation selection switch to the required position (i.e. select the main pump and standby pump), press the start button, the motor starts to start, and the start indicator light is on. When the starting current drops to 1.5 times the rated current, The motor automatically switches to full voltage operation state, and the working indicator light is on. Press the stop button, the motor stops working and the stop indicator light is on. If the current conversion multiple is found to be inaccurate during startup, it shall be adjusted on site according to the actual situation. If some control circuits are converted by time relay, observe the time required for the ammeter to reduce the current to 1.5 times the current from starting to motor, and reset the time setting value of time relay.
3. Automatic operation: close the automatic air switch, select the main pump and standby pump, turn the function switch to the automatic position, and turn on the switches of each sub pump. The water pump controller will automatically start the main pump or put the standby pump into operation or stop the operation of the fire prevention pump according to the liquid level and through the change of the position of the floating ball switch.
4. Fault: when the water pump fails, such as motor overload, phase loss, overtemperature and water leakage of the pump body, the product automatically cuts off the power supply of the motor, terminates the motor operation, and gives corresponding instructions for various faults. If the mutual standby controller is used, the standby pump will automatically switch into operation after any group of main pumps fails.
5. During the starting process of the motor, the operator must monitor whether the controller enters the operation state after starting, so as to avoid damage to the autotransformer and motor caused by too long starting time. For the infrequent water pump controller, such as controlling fire fighting, spray pump and other types of water pumps, it shall start operation and inspection regularly.
6. The autotransformer of the autotransformer step-down control cabinet is allowed to be started twice continuously from the cold state. The starting time of each time is 15s, and the interval time is at least 20s. The starting time of the autotransformer step-down control cabinet can be adjusted through the time relay according to the power of the motor. The adjustable range of delay time is 15-120s。
