浅谈消防水泵接合器的设置问题(Set on fire pump adapter)Set on fire pump adapterAbstract: according to the provisions of the fire pump adapter design specification, this paper elaborates and discusses the water pump adapter in fire protection system set requirements, partition settings and fire water booster, and fire water quantity and the distance, the relationship between the outdoor fire hydrant specific design methods and practices.Keywords: fire, water pump adapter, fire pump, outdoor fire hydrant, fire water tank, booster facilitiesFire pump adapter with fire protection system to connect the interior with a fire truck or pump motor. Fire truck or pump motor through the pump adapter interface, send the fire water to buildings or other liquid fire extinguishing agent, to extinguish fire inside the building, solve the high-rise building or other building in case of fire, the indoor fire pump inside the building due to the maintenance, power outages, failure or indoor water supply pipe at low pressure. The problem of water shortage or not water supply.In our country, fire pump adapter is set as a temporary water supply facilities, water supply to the fire pump is added in water. Different pipeline pump adapter of different uses of the connection point. Here with us to discuss about some problems of pump adapter settings.1, fire pump connector layout requirements: According to the specification and related reference materials and the author participated in the project, the fire pump combination device layout is summarized as follows: (1) fire pump combination device should be arranged outdoors : (2) as far as possible the use of ground type, and should be clearly marked signs: (3) fire pump adapter the site should be located in the fire truck, does not impede traffic: (4) wall adapter and the building should have a certain distance, generally not less than 5m; (5) according to the requirements of the fire pump adapter, and outdoor pool fire hydrant or distance should be 15 ~ 40m, should not be too far away from the water pump (6); the adapter should be dispersedly arranged, when setting the number of not more than 2, may be appropriate to focus on the layout, but the distance between multiple parallel settings should be appropriate, does not affect the use of out of stock.2, pump adapter installed in the fire partition and related connection"Code for fire protection design of tall buildings” (GB50045 -95 (2005 Edition)) "provisions of article 7. 4. 5. 2 of the fire water supply for vertical zoning of water supply, fire water supply pressure range partition, should respectively set pump adapter”. Before that the building height of more than 50m can not be part of the help of fire engines, can consider not set pump adapter, but with updated technology and equipment of fire development, many of the city have been equipped with high-powered fire engines, fire water supply has been far more than 50m, 50m should no longer pump adapter is set as the boundary. According to the "high regulation" provisions, each in the fire water supply pressure range partition must be set separately pump adapter. But the design specification "automatic sprinkler system” (GB50084 - 2001 (2005 Edition)) article 10. 4. 2 "when the pump water supply capacity can not meet the effect at the most unfavorable point of the flow and pressure requirements, should take measures to boost”.Obviously, the "spray gauge" is more strict than the "high standard" on this issue. Fire water booster facilities have two kinds: (1) by means of fire water supply reasonable, such as series water supply pump fire: (2) setting the relay water supply facilities, the relay tank (a) ; (b) the fire pump relay way.The internal water supply of high-rise buildings with vertical zoning of water supply mode, the partition partition fire water supply network independently, so everyone in the fire water supply pressure range partition must be set separately pump adapter. Only the tandem pump way of water supply, water from the district area under the water tank of a water supply, can only set pump adapter in the area under the floor, for the full use of. The pump adapter is connected with the interior ring contacts should be kept away from the fixed fire water pump outlet pipe and indoor pipe network. The water supply mode of series pump is suitable for high building height and high water supply level of city fire engine.Relay water supply way: relay tank water supply and relay fire pump two European ways. However, the disadvantage of relay water supply mode is that normally open and normally closed valves need to be converted by firemen during fire fighting. Valves need to be clear and reliable. And the use of electric valve control, often in the fire can not be guaranteed. It is suitable for the water supply of city fire trucks are highly limited, and building height exceeds the height of feed water pump adapter. The two kinds of relay water supply have their o。
