Research And Development Of Balanced Pressure Foam Proportioning Equipment

The energy issue has been the important issues related to the world economicdevelopment. With the needs of national economic construction and energy strategy, inwhich oil plays an important role. According to the data given by the2011oil and gasindustry at home and abroad Development Report, it can be expected that the country’sdemand for oil can reach the level of490million tons by2012. The oil is a flammableliquid in its processing, storage, transportation process inevitably face the dangers posedby fire. Oil depot fire and explosion is one of the major hazards of petrochemical andstorage industry, the speed of its spread, strong destructive event of fire, if you can notbe suppressed, the direct economic loss is enormous. At the same time, bring casualtiesand environmental disaster is irreparable.The subject as scientific and technological achievements and PromotionAssociation of Shanghai Education Development Foundation in order to better promotethe launch of the year2011by the University science and technology into businessbenefits affiliate program-part of the bid for solving special activities aimed at thedevelopment of efficient oil Irrigation District foam fire extinguishing equipment. Forfoam fire extinguishing system, the core part of the foam proportioning mixing device,foam proportioning device performance largely determines the operating performanceof the whole system.In this paper, mixed a variety of foam proportioning device, identified Selectbalanced foam proportioning device a balanced foam proportioning device is the bestkind of performance of similar products, its safety performance, precise mixing ratio,pressure loss small a wide range of flow and foam large reserves and many otheradvantages. Parts of the research and analysis play a central role, according to the actualneeds and technical requirements, determine the final meet specifications design.In accordance with the design, manufacture or purchase the various components of theprototype and mechanical design in accordance with the design requirements, technicalrequirements on the prototype assembly. In order to verify the performance of theprototype according to GB20031-2005"foam fire extinguishing system and the membergeneral technical conditions", the reliability of the experiments, including the mixingratio of the experiment, the pressure loss experiments run experiment of threeexperiments. According to the national standard requirements, the mixing ratio of theexperimental results of the experiment should be maintained within the design workingpressure range and flow range of3%-3.9%. The pressure loss is another importantindicator to measure the performance of the equipment manufacturer to announce a lossof pressure and flow curve, as an important basis for customers to choose. For reliabilitytest run, requiring the device to run for40minutes under normal circumstances, thedevice as a whole and the respective parts can not be abnormal situation.In order to save the cost of experiments, we first prototype water experiments,estimate the performance of the prototype, and then precise experimental prototype. Theexperimental steps and points to note are implemented in accordance with the technicalrequirements and standards.Through the analysis and processing of the experimental data to validate theperformance of the prototype. The processing of the experimental data results show thatthe prototype compliance with the design requirements, but also meet the nationalstandards. Show that the design is entirely feasible.
