Fire pump in the life is a very important part of the design of fire pump pipe layout is also very important to facilitate the future maintenance and repair, Xiaobian now to say fire pump pipe design considerations . Fire pump line 1, fire pump self-filling suction or from the outdoor municipal green pipe network directly absorb water, the suction pipe must be installed rod valve or reliable locking device butterfly valve 2, a group of fire pump suction pipe is not Should be less than two, when one of the damaged or overhaul, the rest of the suction pipe should be able to pass the entire amount of fire water.3, fire pump suction pipe design flow rate generally used 1.0-1.2m / s (DN.250mm hour) suction pipe The mouth should be set down the bell, the bell mouth below the water level is not less than 0.50m. 4, each fire pump outlet pipe should be installed on the control valve, check valve and pressure gauge. 5, fire pump straight 瓤 outdoor Municipal water supply pipe network, the pump lift calculation should consider the minimum water pressure outside the water supply network, and outdoor water supply pipe network to check the maximum water pressure hydraulic conditions. 6, fire pump should have not less than two The outlet pipe is connected with the annular fire water supply pipe network, and a drain valve for testing and inspection should be installed between the pump outlet pipe control valve and the check valve. The valve diameter is DN65. 7, fire pump outlet pipe design flow rate, generally 1.5-2.0m / s. 8, the system design work pressure P> 1.OMPa fire water supply system should take anti-overpressure measures.
