Fire Engineer What is generally calculated in a fire hydrant system

Number of fire hydrants Hydrant placement spacing Water consumption.

Summary. The purpose of hydrant system calculations is to determine the size and number of pipes, valves, and other equipment that need to be used in the system, as well as the water pressure and flow rate required. This data will be used to ensure that in the event of a fire, the hydrant system can provide sufficient water and pressure to control the fire and protect the building and the people and property inside it.

These calculations need to take into account the size, shape, height, and purpose of the building, the projected water demand, and the requirements of local regulations for fire pools, pump rooms, and other equipment.

The purpose of the hydrant system calculation is to determine the size and number of pipes, valves, and other balances that need to be used in the system, as well as the required water pressure and water flow. This data will be used to ensure that in the event of a fire, the hydrant system can provide enough water and pressure to control the fire and protect the building and its people and property. These calculations need to take into account the size, shape, height, and purpose of the building, the projected water demand, and the requirements of local regulations for fire pools, pump rooms, and other equipment.

I'm still a little confused, can you be more detailed?

The design of a fire hydrant system requires detailed calculations to ensure that in the event of a fire, the system can provide sufficient water and pressure to protect people and property. Here are some factors to consider:1

Size, shape, and height of the building: As a hydrant system covers every corner of a building, it is necessary to determine the water source and equipment in each area, as well as the required water pressure and flow rate. The height and shape of a building can also affect water pressure and flow.

2.Purpose of the building: Different types of cracked buildings have different water needs.

Local fire regulations specify the minimum requirements that a hydrant system should meet, such as pipe size and water pressure. These requirements must be incorporated into the calculations to ensure that the system is compliant with regulations. 4.

Installation of equipment: The location and number of hydrant system equipment (e.g., connecting pipes, valves, and sprinklers) need to be determined to ensure that the system covers the entire building and can be used effectively and sparingly in the event of a fire. 5.

Projected water demand: The amount of water and time required by firefighters needs to be considered, as well as the use of other fire extinguishing equipment such as fire extinguishers. These requirements need to be based on the type and purpose of the building** to ensure that the system can provide the required amount of water and pressure.

In summary, the calculation of a fire hydrant system includes determining the size and number of pipes and equipment, determining water source and water pressure needs, considering the building's use and regulatory requirements, and projected water demand. These calculations are an important step in ensuring that the hydrant system can work effectively in the event of a fire.

The design pressure of fire water supply should meet the pressure requirements of water extinguishing facilities at the most unfavorable points of the various water fire extinguishing systems served.

The pressure of the indoor fire hydrant hydrant and the fire water cannon to enrich the water column shall comply with the following provisions:

1. The dynamic pressure of the fire hydrant should not be greater than; When it is larger, it is necessary to set up a type of non-decompression device;

2. In high-rise buildings, workshops, warehouses and civil buildings with an indoor clearance height of more than 8m, the dynamic pressure of the fire hydrant should not be less than, and the fire water cannon should be calculated as 13m; In other places, the dynamic pressure of the fire hydrant should not be less than, and the water column of the fire water gun should be calculated as 10m.

The fire water supply pressure in the pipeline of the indoor fire hydrant system of the urban traffic tunnel should ensure that when the water consumption reaches the maximum, the minimum pressure should not be less than, but when the water outlet pressure at the mouth of the fire hydrant exceeds it, the pressure reducing facility should be set up;

Summary. Fire protection systems include, outdoor fire hydrant system, indoor fire hydrant system, fire extinguisher system, and some will have automatic sprinkler system, water cannon system, gas fire extinguishing system, fire detection system, water mist system, etc. The fire hydrant set is generally composed of fire box + fire hose + water gun + buckle + bolt + clip, etc., the fire hydrant is mainly used by fire trucks to take water from the municipal water supply pipe network or outdoor fire water supply pipe network to extinguish the fire, and can also be directly connected to the hose and water gun to extinguish the fire.

Therefore, the indoor and outdoor fire hydrant system is also one of the important firefighting facilities for fire fighting.

The installation height of the fire hydrant in the fire hydrant system is generally a b Hello dear, I am happy to answer for you: The installation height of the fire hydrant in the fire hydrant system is generally a b Reply as follows: The positive installation height of the fire hydrant in the fire hydrant system is generally a fire hydrant, officially called a fire hydrant, a fixed fire fighting facility, the main role is to control the elimination of combustibles, isolate combustibles, and eliminate the source of ignition.

Hello fire protection system includes, outdoor fire hydrant system, indoor fire hydrant system, fire extinguisher system, and some will also be buried in the automatic sprinkler system, water cannon system, gas fire extinguishing system, fire detection system, water mist system and so on. The fire hydrant set is generally composed of fire box + fire hose + water gun + buckle + bolt + clip, etc., the fire hydrant is mainly used by fire trucks to take water from the municipal water supply pipe network or outdoor fire water supply pipe network to extinguish the fire, and can also be directly connected to the hose and water gun to extinguish the fire. Therefore, the indoor and outdoor fire hydrant system is also one of the important firefighting facilities for fire fighting.

Zhejiang Provincial Quota: If the pipe diameter is below DN32, the bracket has been included in the quota, but the bracket paint should be calculated separately.

Maximum spacing of horizontal pipe supports:

dn15: m,

DN20: 3 meters.

DN25: m.

DN32: 4 meters.

DN50: 5 meters.

DN70: 6 meters.

DN80: 6 meters.

DN100: meters.

DN125: 7 meters.

DN150: 8 meters.

Vertical pipe support spacing: one per floor.

The number of stents * the weight of a single bracket can be used to obtain the weight of the stent.

The fire hydrant system mainly involves the following engineering quantities to be calculated.

1. Fire hydrant dry pipe.

2. a riser. 3. Branch pipes.

4. Fire hydrant box.

5. Valve (butterfly valve).

6. Wear the floor casing.

7. a pipe support.

8. Fire pump adapter.

However, the quantity calculation related to the examination is mainly the effluent flow of indoor and outdoor fire hydrants.

Answer]: a, according to the "Code for the Configuration and Design of Building Fire Extinguishers", there is no indoor local rock fire hydrant system and fire extinguishing system, and the correction coefficient of the fire extinguisher configuration is; The correction coefficient of the fire extinguisher configuration with indoor fire hydrant system is; The correction factor of the fire extinguisher configuration with fire extinguishing system is as follows; The value of the correction factor for the configuration of the fire extinguisher with an indoor fire hydrant system and a fire extinguishing system is.

Number of fire hydrants and installation distance.
