Integrated foam performance detection box and detection method

Abstract

The invention discloses an integrated foam performance detection box. The integrated foam performance detection box comprises a measuring device and a foam collector which are arranged in a detection box body, wherein the top of the measuring device is an electronic balance, and is provided with a temperature sensor, a controller, a display screen and an operation panel; the foam collector comprises a foam receiving tank, a connecting pipe and a separated liquid receiving tank which are connected from top to bottom, the foam receiving tank is supported on a supporting frame, the top of the foam receiving tank is of an open structure, the bottom of the foam receiving tank is a necking pipe opening, and a filter screen is embedded in a top end of the connecting pipe; an upper end of the connecting pipe is inserted into a pipe opening of the foam receiving tank, a valve is arranged in the middle section of the connecting pipe, and a lower end of the connecting pipe is connected into the separated liquid receiving tank. The device has the characteristics of high integration level, small size, light weight, easiness in carrying, simplicity and convenience in operation and automatic calculation, can realize synchronous measurement and rapid calculation of important foam performance parameters such as foaming times and 25% drainage time, and greatly saves the foam performance measurement cost.

Description

technical field [0001] The invention relates to foam fire extinguishing equipment performance detection technology, in particular to an integrated foam performance detection box and detection method. Background technique [0002] In major core production devices such as UHV converter transformers, compressed air foam fire extinguishing systems play an important role in ensuring the safe and stable operation of production equipment. Generally speaking, the foam fire extinguishing agent and the foam fire extinguishing system cooperate with each other and play a synergistic fire extinguishing effect. The compressed air foam fire extinguishing system involves the three-way two-phase mixing technology of fire water, foam liquid and compressed air, the type of fire extinguishing agent, the mixing of foam solution, and the pipe Both the net delivery and release method affect the foam performance of the fire suppression system. In actual engineering, the commissioning, acceptance, ...

AI Technical Summary

Problems solved by technology

At the engineering site, the foaming ratio is often measured by simple instruments such as plastic buckets, resulting in large errors in the test data, and it is difficult to accurately reflect the quality of the system engineering; 25% liquid analysis time is an important parameter to measure the stability of the foam, due to the lack of effective measurement methods. Affected the commissioning and engineering acceptance of the compressed air foam fire extinguishing system project

[0003] At present, the foam performance testing device specified in GB 27897-2011 "Class A Foam Fire Extinguishing Agent" has many components and large volume, which cannot be used for engineering site testing

Although CN 201681030U provides a low multiple foam fire extinguishing agent on-site detection device, the device has many components, cumbersome methods, and slow detection speed. The detection results rely entirely on manual on-site calculations, and it is difficult for some personnel to master the measurement method. In addition, it is limited to 25% Liquid analysis time is limited, and 25% of the liquid analysis time is often missed during operation
