Integrated ground box pump Jilin fire box pump integrated manufacturer advantages of box pump integration

Description :

Integrated ground tank pumpWhen the fire alarm does not occur and the system is in automatic operation, the pressure sensor on the fire pipe network samples the water pressure of the pipe network, converts the pressure signal into an electrical signal, and transmits it to the PID regulator. Then, it compares and calculates with the pressure value set by the user, and converts the comparison and calculation results into frequency adjustment signals and signals for the number of stable pressure pumps to be started, which are respectively sent to the frequency converter and programmable logic controller (PLC): the frequency converter adjusts the electrical frequency of the pump motor accordingly.

　　Jilin Changchun Stainless Steel Box Pump Integrated Stable Pressure Water Supply Equipment - Fire Box Pump Integration to Adjust Pump Rotation: The programmable controller controls the operation of the stable pressure pump based on the pump start signal transmitted from the PID regulator. By adjusting the number of pumps that start and stop, as well as the speed of the stabilizing pumps that operate with positive frequency conversion, the water pressure in the user's fire protection pipeline network is kept constant at the pre-set pressure value, in order to maintain a low fire protection pressure and prepare the entire system for fire protection. When a fire alarm occurs, the control cabinet will receive a pump start signal from the station control room.

　　Jilin stainless steel box pump integrated pressure stabilizing water supply equipment immediately started the fire main pump and turned off the pressure stabilizing water pump, providing rated fire water to meet the requirements of fire water injection to enrich the water column. After the fire command is lifted, manually shut down the main fire pump to restore the equipment's daily stable voltage state. Meet the requirements of fire water injection to enrich the water column. After the fire command is lifted, manually shut down the main fire pump to restore the equipment's daily stable voltage state.

　　Water flow rate: Fire pump: 40I/s; Pressure stabilizing pump: 1_5 L/s Supply pressure: Fire pump: 0.6MPa Pressure stabilizing pump: 0.7MPa Number of pumps *: 2 fire pumps; 2 stabilizing pumps with single pump power

　　Jilin Stainless Steel Box Pump Integrated Stable Pressure Water Supply Equipment Fire Pump: 37kW; Stable Pressure Pump: 4.0kW Constant Pressure Accuracy:<0.01MPa Control Mode: Constant Pressure Control, Station Control Room Command Control Operation Mode: Manual, Automatic Fire Main Pump Start Mode: 5KW direct start; &18.5KW star delta voltage reduction starting.

　　The Jilin stainless steel box pump integrated pressure stabilizing water supply equipment adopts a fully enclosed operation mode, without the need to build a water tank, which can save construction investment and effectively solve the secondary pollution phenomenon of traditional water supply methods. The integrated composition of the roof box pump mainly consists of a variable frequency speed regulation water pump unit, a steady flow compensator, a vacuum suppressor, pressure and flow sensors, a pre pressure self balancing device, a control cabinet, a filter, a backflow preventer, etc.
