What are the common water supply equipment on the market?

(1) high water tank. Automatic sprinkler system using a temporary high-pressure water supply system, should set up the high fire water tank, the water storage should be 10min fire water, fire water tank water supply system should meet the nozzles at the most unfavorable point of the minimum working pressure and water density.
The building height not more than 24m, and set the dry wet system, system or preaction system according to the light danger level or dangerous level places, such as setting a high water tank is difficult, should use the 5L/s flow of the air pressure water supply equipment with water supply at the early stage of 10min.
The water pump a system, should be independent, and should be a preparation or a preparation will set the standby pump ratio.
B, according to the two load power supply of the building, it is appropriate to use the diesel pump as a standby pump.
C, the system of water supply pump, pressure regulator pump, should use the self irrigation water absorption method. When using natural water, the water pump should take measures to prevent the blockage of the debris.
4) each water supply pump should not be less than 2. The alarm system is provided with an annular pipeline valve population before each water pump outlet pipe should not be less than 2. Water pump water supply pipe should be set up control valve control valve, outlet pipe should be set up; check valve water valve, pressure gauge and a diameter not less than 65mm. When necessary, should take measures to control the outlet pressure of the water supply pump.
(3) fire pool. Fire water pool is used for indoor fire protection in the absence of outdoor fire source. Fire water tank can be arranged on the outdoor underground or on the ground, or in the basement or indoor, and indoor swimming pool, pool and waterscape. Fire water tank shall be provided with a water level control valve of the water inlet pipe and an overflow pipe, vent pipe, drain pipe, a water outlet pipe and a water level indicator and other ancillary equipment. According to the requirements of water quality of all kinds of water system, the fire pool and the life or production of water storage
(4) air pressure water supply equipment or regulated water pump. Air pressure water supply equipment is based on Boyle's law, that is: under constant temperature conditions, the absolute pressure of a certain quality gas and its volume is inversely proportional to the principle of manufacturing. It uses the pressure of the compressed air in the airtight tank to change, adjust and pressure water supply, in the water supply system, mainly from the role of pressure and water regulation.
When the high water tank can not meet the building, the most unfavorable point of the construction of automatic water spray fire extinguishing system, should be set pressure water supply equipment, such as pressure pumps and other booster facilities
