On July 17, 2009, the “2009 Gas Pressure Emergency Fire Pressure Water Supply Equipment Technical Exchange and Product Promotion Conference†jointly held by Beijing Fire Protection Association, Shanghai Liancheng Group and China Architecture Society Fireproof Comprehensive Technology Branch was successfully held.
The meeting introduced the performance of the high-level water tank replacement technology for building fire-fighting water supply--the performance of the "DLC gas pressure-pressure emergency fire-fighting water supply equipment". The technical product solves the shortage of the pressure tank to replace the high-level water tank, which was numerous in the 2008 Beijing Olympic Games. It is widely used in stadiums and other key buildings.
Fire pressure water supply equipment usually consists of a pressure water tank, a water pump unit, an electric control cabinet and accessories. Equipment that can supply water to the fire protection pipe network when the pump is started or stopped.
Classification of fire pressure water supply equipment
1) According to the working mode of the pressure water tank, it is divided into (1) air supply type fire pressure water supply equipment (2) capsule type fire pressure water supply equipment (3) nitrogen pressure pressure fire pressure water supply equipment 2) according to whether the fire pump component is provided a. Common fire pressure water supply equipment with fire pump set b. Emergency fire pressure water supply equipment without fire pump set
Who should design the equipment for fire pressure?
1) The manufacturer of the pressure water tank shall hold a pressure vessel manufacturing license or registration and have a sound quality management system and system. 2) The purchased parts of the equipment must have the product certificate and can be used after passing the inspection. The components such as the pressure water tank, water pump unit and electrical components of the equipment shall be assembled and used only after passing the inspection. The on-site performance can be checked on-site using equipment assembled on site. 3) A production license issued by the relevant department should be held. 4) When selecting this product, the following requirements should be made: equipment composition, equipment classification, equipment working pressure, equipment design flow rate, pressure tank specification quantity, equipment material, and sanitary requirements. 5) The overall structure of the equipment, the arrangement of the water pipeline, the gas pipeline and the electrical circuit should be reasonable, and the installation and maintenance space should be left for easy operation. 6) A safety valve shall be provided on the pipeline of the equipment, and its opening pressure is not more than 1.1 times the highest working pressure. 7) Fire-fighting and living (production) shared equipment must have separate fire outlets.
DLC gas pressure emergency fire pressure water supply equipment
High-rise building fire water supply often uses pressure tanks instead of high-level water tanks to meet the initial water consumption of 10min fire-fighting, but often chooses ordinary pressure tanks to occupy a larger space.
The DLC series of gas pressure fire water supply equipment produced by Shanghai Liancheng Company is GB50015-2003 "Design Code for Building Water Supply and Drainage", GBJ16-87 "Code for Fire Protection of Building Design", GB50045-95 "Code for Fire Protection Design of High-rise Civil Buildings", GB50084 -2001 "Design Specification for Automatic Sprinkler System" is based on design; GA30.1-2002 "Performance Requirements and Test Methods for Fixed Fire Water Supply Equipment Part 1: Fire Pressure Water Supply Equipment", Q/IFNM9-2004 "Gas Top Pressure fire water supply equipment is a new type of fixed fire extinguishing device produced by standard. The device is composed of a pressure water tank, a voltage regulator, a container device, a gas stop device, an electric control system, etc., and the tank volume is 1/3 to 1/5 of the ordinary pressure tank, and the water supply pressure is stable, which is ideal. Large emergency fire pressure water supply equipment.
Features
1. The design, manufacture, pressure test, inspection and acceptance of the pressure water tank and assembly device of DLC products are in accordance with GB150-1998 "Steel Pressure Vessel" and GB5099-1994 "Steel Seamless Gas Cylinder". It is stipulated that the liability insurance for container equipment shall be underwritten by the People's Insurance Company of China; 2. The water pump equipped with DLC products shall pass the type inspection of the National Fire Equipment Quality Supervision and Inspection Center, and the quality shall comply with GB6245-1998 “Fire Pump Performance Requirements and Test Methodsâ€;
3, DLC products have advanced multi-function programming control, can receive a variety of fire signals and can be connected with the fire center; 4, DLC products with two power interfaces, with dual power automatic switching function; 5, DLC product gas pressure The device is equipped with dry battery backup power supply, and the fire extinguishing performance is safe and reliable. 6. The accessories used by DLC products have been screened by many manufacturers, with reliable product quality assurance, key components in standard products, such as: motor and water pump bearings. , programmable controllers, circuit breakers, contactors, relays, etc. use international and domestic famous brand products; 7, DLC products can store 10 minutes of fire water, can replace indoor fire water tanks, with investment, short construction period, easy construction and installation It is easy to realize the advantages of automatic control, especially suitable for earthquake zone construction, concealed works, temporary buildings and buildings that are not suitable for setting high water tanks due to architectural requirements.
Environmental conditions
1. Ambient temperature: 5~40°C; 2. Relative humidity of air: ≤85% (at 20±5°C); 3. Medium temperature 4~70°C; 4. Power supply voltage: 380V (+5%-10%)
