Life jacket buoyancy loss tester GB/T32227—2015 Shanghai Chengsi

Life jacket buoyancy loss tester instrument use: buoyancy testing of buoyancy body materials (such as air bags, foam plastic, kapok bags, etc.
) and life jacket products, used to analyze the relationship between
material structural properties and buoyancy and buoyancy retention.
Meet the standards: GB 4303-2008GB/T32232-2015 children's life jackets and other standards
.
GB/T32227—2015 Instrument characteristics: 1.
Pressure sensor range: 0-150N; 2.
The test box is made of sampling acrylic, no rust, and the appearance is neat; 3.
Upper pressure plate: grid-like design, adjustable relative position up and down, detachable; 4.
Test result: buoyancy value (N); 5.
Water level control mode: automatic positioning of the equipment, manual control and positioning; 6.
Force test: system automatic test, digital display; 7.
The touch screen adopts 7-inch color, and the operation interface switches between Chinese and English 8.
Fully automatic downward pressure immersion mechanism, which is stable and practical9.
1 stainless steel 304 net basket; 10.
The instrument adopts imported servo motor, which runs smoothly, has low noise and high precision; Put the life jacket into the non-absorbent net basket and immerse it in the fresh water surface for 100mm, and after 24h, measure and calculate the buoyancy according to the following steps: a) Place the dynamometer with an accuracy of 1N above the pool, immerse the non-absorbent net basket in water and hang it on the dynamometer, and record the buoyancy W net; b) Put the life jacket into the non-absorbent net basket, immerse it in water and hang it on the dynamometer, and record the buoyancy W1 after the life jacket is immersed in water for 24h; c) Life jacket buoyancy W float Calculated by equation (2): W float = W net -W1.
