Overview

How much water does an integrated fire water tank for underground pumping stations generally hold? Scope of application: It is widely used in various fire water supply systems such as fire hydrant water supply systems, automatic sprinkler systems, water fire extinguishing systems, and fixed fire monitor fire extinguishing systems that require pressurization facilities in newly built, expanded, and renovated industrial and civil buildings.

How much water is usually stored in the integrated fire water tank of buried pump stations

There is no significant impact on the underground fire water tank. If there is an automatic fire extinguishing system in the community, it is necessary to have a fire water tank and a rooftop fire water tank. Because the fire water pool is part of the entire fire protection facility system, and the fire water pool is located in the basement, it has little impact on the owners of the entire community, does not affect the community environment, and does not cause noise pollution.

How much water is usually added

1. The inlet pipe of the fire water tank should be determined based on its effective volume and replenishment time, and the replenishment time should be ≤ 48 hours; however, when the effective total volume of the fire water tank is greater than 2000m3

When replenishing water, the time should not exceed 96 hours; the diameter of the inlet pipe of the fire water tank should be determined through calculation and should not be less than DN100;

2. When the fire water pool adopts two fire water supplies and can continuously replenish water to meet the fire protection requirements in case of a fire, the effective volume of the fire water pool should be determined according to the calculation

Fixed, but should not be less than 100m3. When only a fire hydrant system is installed, it should not be less than 50m3.

3. When the total effective storage capacity of the fire water tank is greater than 500m3, it is advisable to set up two independently usable fire water tanks; When it is greater than 1000m3, it should be set to be able to independently

Two fire water pools for immediate use.

Each (or each) fire water tank should be equipped with an independent outlet pipe and a connecting pipe that meets the effective water level, and its diameter should be able to meet the design flow of fire water supply

Post maintenance precautions for integrated automatic water supply equipment with box and pump: If the paint peeling off is found on the tank body of the integrated fire box and pump, it should be painted and maintained in a timely manner to extend the service life of the equipment.

Working principle of integrated fire box pump (fire type, life type): When the system is in a stable state, due to the discharge of some gas by the water in the pressure tank, the pressure inside the tank decreases. When the pressure drops to a certain level, the pressure sensor sends out a signal, and the electromagnetic valve is opened through the electric control box to discharge the water in the tank. When the water level drops, the electromagnetic valve closes and the liquid level sensor sends out a signal to control the water replenishment pump to start working, replenishing water and air to the pressure tank. When the water level reaches the upper limit, the actual water pump stops, but the pressure inside the tank does not reach the set working pressure, the solenoid valve opens, and the tank is drained.
