Foam liquid appearance quality inspection and inspection

The so-called visual quality inspection of foam liquid is to observe the appearance and check whether it is qualified.

The appearance quality inspection of foam liquid is to observe whether it is deformed and other mechanical damage, whether the exposed non-mechanical processing surface protective coating is intact, whether the machining surface without protective coating is rusted, whether all exposed interfaces are damaged, whether the blockage, cover and other protective objects are well encapsulated, whether the nameplate mark is clear and firm, whether the fire pump runs flexibly, whether there is blocking or abnormal sound, whether the high-power foam generator rotates the impeller by hand is flexible, and whether the manual mechanism of the fixed foam bubble is jammed.

The standards for sending foam liquid for inspection are: the design amount of 6% type low power foam liquid is greater than or equal to 7.0t; the design amount of 3% type low power foam liquid is greater than or equal to 3.5t; the minimum reserve amount of 6% protein type medium power foam liquid is greater than or equal to 2.5t; the minimum reserve amount of 6% synthetic medium power foam liquid is greater than or equal to 2.0t; the minimum reserve amount of high multiple foam liquid is greater than or equal to 1.0t; the contract stipulates that on-site sampling and testing of foam liquid is required.

If the appearance quality inspection is to judge the quality of the foam liquid by observation, etc., then the inspection is to test whether the foam liquid is qualified by the exact data.
