摘要
Abstract
The spraying performance is one of the key performance of fire extinguishers.When optimizing the design of fire extinguisher structures,it is necessary to build a fire extinguisher measurement and control platform to evaluate the spraying performance of the fire extinguisher.On the basis of the overall design of the fire extinguisher measurement and control platform,LabVIEW is used to construct a fire extinguisher spraying performance measurement and control system,a data collection and processing device are designed to monitor the quality changes of the fire extinguisher bottle,and a motion control device is built to simulate the process of manual pressure on the pressure rod during actual use.Subsequently,through this measurement and control platform,the performance of the fire extinguisher,such as spraying delay time,effective spraying time,spraying residual rate,and effective spraying distance,can be analyzed.The analysis of experimental results shows that the main factors affecting the effective spraying time of fire extinguishers are the filling pressure value and nozzle hole diameter of the fire extinguisher.The general factor is the length of the fire extinguisher's nozzle,and the influence of nozzle hole length on the effective spraying time of the fire extinguisher is much smaller than the filling pressure value and nozzle hole diameter.To ensure a longer spraying time,the preferred parameters for the fire extinguisher:filling pressure is 1.2 MPa,nozzle diameter is 2.3 mm,and nozzle length is 500 mm.关键词
