1. Tap water pipe network water supply: this way is easier, indoor water supply directly from the external tap water pipe network water supply. Its structure is simple, makes full use of the water pressure of the external network, and saves energy. But since there is no internal water, once the external network is shut down, the internal water will turn off, reducing reliability. This method can be used when the water supply and pressure of the external water supply network are stable and the water supply and pressure required by the hydrant device can be satisfied at any time in the vulnerable area of the system.

2. Water tank water supply: in a relatively high place to install stainless steel water tank, adjust the flow and pressure. Reliable water supply to maximize external pressure. However, the need to install a high water tank added to the burden of the building. If the pressure of the outdoor pipe network can meet the pressure requirements most of the time, and the pressure of the outdoor pipe network is low and cannot meet the pressure requirements of the indoor fire hydrant in the peak period of water consumption, the water supply method is as follows: I can. It will be used.

3. Water pump and water tank coordination water supply: when walking on the road, there may be red water pump, but this is the actual water supply. At the same time equipped with water pump and stainless steel fire tank efficiency is higher. The fire extinguishing water in the system is generally supplied from the roof tank, and the stainless steel fire extinguishing water tank is regularly replenished by the production and domestic pumps. When a fire breaks out, pumps can start supplying water to the system. If the water pressure of the external water supply network cannot provide the water pressure required by the internal fire water supply system in time. This type of water supply should be used. If the fire pump cannot absorb water directly in the outdoor pipe network, the fire pool should be installed.
