Abstract

The invention belongs to the field of foam stability measurement, particularly relates to a device for measuring foam stability, and provides the following scheme in order to solve the problems that in the prior art, foam cracking and collapse pressure changes cannot be monitored in real time, and manual reading is high in error. The device comprises a paperless recorder, a wind pressure transmitter, a mass flow meter, a test tube, a reference tube, a pressure reducing valve and an N2 gas cylinder, the upper end of the N2 gas cylinder is provided with an N2 gas port, the left end of the N2 gasport is connected with an N2 gas pipe, the left end of the N2 gas pipe is provided with the pressure reducing valve, and a first gas pipe three-way connecting piece is connected among the three sections of the N2 gas pipe. The device is suitable for researching the dynamic defoaming process of foam, recording the pressure generated by the foam in real time and measuring the stability of the foam.The device is simple in structure and low in cost, can realize visual observation of the foam pressure change in the whole process of foam collapse and rupture, and has important significance for quantitatively representing the foam stability.

Description

Technical field [0001] The invention relates to the field of measuring foam stability, and in particular to a device for measuring foam stability. Background technique [0002] Foam extinguishing agent is an effective extinguishing agent for extinguishing flammable and combustible liquids. It is mainly used to form a condensed foam floating layer on the surface of the liquid, which acts as suffocation and cooling, and is used to fight non-water-soluble combustible liquids and general solid fires. Foam fire extinguishing agents are divided into chemical foam, air foam, fluoroprotein foam, aqueous film-forming foam and alcohol-resistant foam. In order to accurately evaluate the technical performance of the foam solution, it is necessary to refer to the technical indicators of the foam solution evaluation according to "GB15308-2006-Foam Extinguishing Agent", including foaming ratio, pH value, 25% drainage time, 50% drainage time, etc. index. Among them, 25% drainage time and 50% d...
