630A Integrated Distribution Cabinet Mechanical Emergency Fire Pump Controller

Sprinkler Pump Mechanical Emergency Start Control Integrated Distribution Cabinet

Product Overview

The fire control cabinet mainly consists of the main power supply circuit breaker, AC contactor, programmable PLC, intermediate relay, touch mode screen and other electrical components.When the control cabinet control system receives the fire control signal or network pipe pressure and pool level of the control center, the fire pump is immediately started or stopped to realize the function of automatic pump opening and stopping, and can store all work records and fault records.

Our company has independently developed an automatic fire control cabinet integrating alarm, monitoring, control and management, and has been put into production and use. When fire occurs, the fire signal, automatically start the pump. In case of control cabinet failure, the mechanical emergency start device to force the pump to achieve fire extinguishing function.The product complies with the technical specifications of the national standard GB 27898.3-2011 and is inspected and certified by the National Fire Engineering Technology Research Center.

Model Meaning

Start Mode Selection

• Advantages And Disadvantages Of Direct Startup

Advantages:less required elements, simple start mode, more suitable for small power motor.The current directly started by the motor is more than 5 times that of normal operation. In theory, as long as the line and transformer capacity providing power to the motor are more than 5-7 times the motor capacity, they can be directly started, and most of the small capacity motors are directly started.

Disadvantages: For large-capacity motors, on the one hand, it is difficult for the line and transformer capacity providing power supply to meet the conditions of direct motor start, on the other hand, the powerful starting current shocks the power grid and the motor, affecting the service life of the motor, and is adverse to the power grid.

• Advantages And Disadvantages Of Soft Startup

Advantages: little impact on power grid voltage fluctuation, small impact on power grid, good protection on electric motor, extend the life of electric motor, and more suitable for high power and heavy load motor.When the motor is directly started at full voltage, the starting current will reach 4-7 times the rated current. When the capacity of the motor is relatively large, the starting current will cause a sharp drop in the power grid voltage and affect the normal operation of other equipment with the power grid.When the soft start, the start current is generally 2-3 times the rated current, and the voltage fluctuation of the power grid is generally within 10%, so the impact on other equipment is very small.

Disadvantages; high investment, high environmental requirements for use, and low overload capacity of electronic original.

• Advantages And Disadvantages Of Self-Lotus Root Antihypertensive Initiation

Advantages; the environment is not high, less faults.It is to reduce the voltage after reducing the motor, which can adjust the voltage freely.

Disadvantages: large voltage current, large impact torque, there are secondary shock current and shock torque in the starting process, can not start frequently, the protection of the motor is poor.

• Advantages And Disadvantages Of Star Triangle Initiation

Advantages: Star triangle start is after changing the wiring mode of the motor to realize the pressure reduction, the equipment is relatively simple and more economical.

Disadvantages: star triangle start connection, large investment, and the start has a certain impact on the grid.
