本機(jī)專為沙發(fā)彈簧框架和彈簧包而設(shè)計(jì)的測試儀器，它可滿足以下三種測試要求

This tester is designed for the test of the zig-zag spring assembly and spring pack used in sofa manufacturing , it can perform the following 3 kinds of test requirements:

1）      耐久性測試 / Durability Test

可按預(yù)設(shè)定之壓力條件進(jìn)行重複按壓測試，週期可預(yù)設(shè)定，到數(shù)自動(dòng)停止。

The spring undergone a repeated specific force , the test cycles is pre-settable, and the test stop when the set cycle is up。

2）壓縮量程與壓力關(guān)係檢測 / Fix stroke test

壓板按預(yù)設(shè)定行程下壓， 到位停止。在壓力錶上讀取該行程的彈簧力。

The presser comes down to a specify stoke, read the force on that stroke from the pressure gauge.

3）特定壓力下彈簧壓縮量檢測 / Fix force test

   壓板下壓至設(shè)定壓力後停止，顯示幕上顯示該壓力值的壓縮行程長度。

   The presser comes down to a specify force, the presser stop and the compression rate (stroke)

   will be displayed on the screen.

專門用於測試沙發(fā)坐墊的彈簧框架及彈簧包和彈簧坐墊的耐久性和承受力 specialize using in testing the durability and endure of sofa’s spring frame and spring pack.
