Abstract

The invention relates to the technical field of fire extinguisher product detection, in particular to a fire extinguisher injection performance test device and a fire extinguisher injection performance testing method. The fire extinguisher injection performance test device comprises a base, first dust concentration sensors, a data acquisition and analysis terminal and a weighing sensor arranged onthe base, the number of the first dust concentration sensors is multiple, the multiple first dust concentration sensors are arranged at intervals in the fire extinguishing agent spraying direction ofa fire extinguisher for testing, and the data acquisition and analysis terminal is connected with the first dust concentration sensors and the weighing sensor. The fire extinguisher injection performance test device provided by the invention can automatically measure the injection distance of the fire extinguisher, and eliminates the influence of manual operation in the test process; the fire extinguisher injection performance test method provided by the invention can save the labor cost.

Description

technical field [0001] The invention relates to the technical field of fire extinguisher product testing, in particular to a fire extinguisher spray performance test device and a fire extinguisher spray performance test method. Background technique [0002] Fire extinguishers are commonly used fire-fighting equipment, which play an important role in extinguishing initial fires and preventing fires from spreading, and their quality can directly affect the fire-extinguishing effect. The relevant technical standards of fire extinguishers have strict restrictions on the performance indicators of fire extinguishers, and these performance indicators need to be determined through relevant tests. According to "Portable Fire Extinguisher Part 1: Performance and Structure Requirements" (GB4351.1-2005), the description of the test method for the spray performance of fire extinguishers, the spray distance is defined as: when the fire extinguisher sprays 50% of the fire extinguishing dos...
