本机专为沙发弹簧框架和弹簧包而设计的测试仪器，它可满足以下三种测试要求

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)耐久性测试 / Durability Tes 可按预设定之压力条件进行重复按压测试，周期可预设定，到数自动停止。

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

2)压缩量程与压力关系检测 / Fix stroke test

压板按预设定行程下压， 到位停止。在压力表上读取该行程的弹簧力.

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

3)特定压力下弹簧压缩量检测 / Fix force test

压板下压至设定压力后停止，显示屏上显示该压力值的压缩行程长度。

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

will be displayed on the screen.

注:

a) 本机最大压力 = 80 公斤， 最高按压行程150 mm。

b) 压力传感器精度:0.3% FS

c) 行程精度 : ±0.2 mm

d)电源: 220伏, 功率= 400瓦
