The following is aboutFire booster and voltage stabilizing complete equipmentDetailed data and explanations for the selection guide:

1.Fire booster and voltage stabilizing complete equipmentA basic overview of

Fire booster and voltage stabilizing complete equipmentIt is a set of equipment specially used in fire protection systems, designed to provide stable water pressure and flow to ensure rapid and effective water supply when a fire occurs. The device usually includesbooster pump, pressure surge tanks, control systems, pipes, valves and other components.

2.Basic structure and components

2.1booster pump

• type:Multistage centrifugal pump,Single stage centrifugal pump,Self-priming pumpwait.
• Material: Cast iron, stainless steel, etc.
• Function: Provide the required water pressure and flow to ensure that the fire protection system can quickly supply water when a fire occurs.

2.2 Pressure tank

• type: Pressure tanks, diaphragm tanks, etc.
• Material: Carbon steel, stainless steel, etc.
• Function: Stabilize the system pressure, reduce the number of pump starts, and extend the service life of the pump.

2.3 Control system

• type: PLC control, relay control, etc.
• Function: Automatically control the start and stop of the pump, monitor system pressure and flow, and ensure that the system can operate normally in the event of a fire.

2.4 Pipes and valves

• Material: Carbon steel, stainless steel, PVC, etc.
• Function: Connect various components to control the direction and flow of water flow to ensure the normal operation of the system.

3.Working principle

Fire booster and voltage stabilizing complete equipmentpassbooster pumpProvide the required water pressure and flow, the pressure tank is used to stabilize the system pressure, and the control system automatically monitors and adjusts the operating status of the system. When the system pressure is lower than the set value, the control system startsbooster pump, providing the required water pressure; when the system pressure reaches the set value, the control system stopsbooster pump, to maintain the stable operation of the system.

4.Performance parameters

4.1 Flow (Q)

• definition: The amount of liquid delivered by the equipment per unit time.
• unit: Cubic meters per hour (m3/h) or liters per second (L/s).
• scope: Typically 10-500 m3/h, depending on the model and application of the equipment.

4.2 Lift (H)

• definition: The device can raise the height of the liquid.
• unit: Meter (m).
• scope: Usually 50-500 meters, depending on the model and application of the equipment.

4.3 Power (P)

• definition: The power of the equipment motor.
• unit: kilowatt (kW).
• Calculation formula：( P = \frac{Q \times H}{102 \times \eta} )
  • (Q): flow rate (m3/h)
  • (H): Lift (m)
  • ( \and ):pumpefficiency (usually 0.6-0.8)

4.4 Efficiency (η)

• definition: The energy conversion efficiency of the device.
• unit:percentage(%).

6.Selection guide

6.1 Determine demand parameters

• Flow(Q): Determined according to system requirements, the unit is cubic meters per hour (m3/h) or liters per second (L/s).
• Lift(H): Determined according to system requirements, unit is meter (m).
• Power(P): Calculate the power requirement of the pump based on the flow rate and head, in kilowatts (kW).

6.2 Select pump type

• Multistage centrifugal pump: Suitable for high lift requirements, high efficiency and stable operation.
• Single stage centrifugal pump: Suitable for medium and low lift requirements, with simple structure and easy maintenance.
• Self-priming pump: Suitable for situations where self-priming function is required, such as when the water source is unstable.

6.3 Select pump material

• Pump body material: Cast iron, stainless steel, bronze, etc., selected according to the corrosiveness of the medium.
• Impeller material: Cast iron, stainless steel, bronze, etc., selected according to the corrosiveness of the medium.

6.4 Select brand and model

• Brand selection: Choose well-known brands to ensure product quality and after-sales service.
• Model selection:Select the appropriate model based on demand parameters and pump type. Refer to the product manuals and technical information provided by the brand.

7.Maintenance and care

7.1 Regular inspection

• Check content:pumpThe operating status, the pressure of the pressure stabilizing tank, the working status of the control system, the sealing of pipelines and valves, etc.
• Check frequency: It is recommended to conduct a comprehensive inspection once a month.

7.2 Regular maintenance

• Maintain content: Clean the pump body and impeller, check and replace seals, lubricate bearings, calibrate control system, etc.
• Maintenance frequency: It is recommended to perform comprehensive maintenance every six months.

7.3 Troubleshooting

• Common faults: Pump does not start, insufficient pressure, unstable flow, control system failure, etc.
• Solution: Troubleshoot according to the fault phenomenon, and contact professional technicians for repair if necessary.
