拉力试验机与多功能拉力试验机的原理

多功能拉力试验机采用机电一体化设计,主要由测力感测器、变送器、微机处理器、负荷驱动器、电脑及彩色喷墨打印机构成。高精度调速电动机可设置五档试验速度。各集成构件间均采用插接方式连接。功能与作用电脑全程控制并显示试验全过程和曲线、微机自动传输试验设置与试验资料。多功能拉力试验机广泛使用于各类五金、金属、橡塑胶、鞋类、皮革、服装、纺织、绝缘体、电线电缆、端子……等各类材料。预测其拉伸、撕裂、剥离、抗压、弯曲抗剪力、三点抗折……等各项物性测试性能。 拉力试验机是用来对材料进行静载、拉伸、压缩、弯曲、剪切、剥离等力学性能试验用的机械加力的试验机,适用于塑料板材、管材、异型材,塑料薄膜及橡胶、电线电缆等材料的各种物理机械性能测试为材料开发,为物性试验、教学研究、质量控制等不可缺少的检测设备,源峰拉力机夹具作为仪器的重要组成部分,不同的材料需要不同的夹具,也是试验能否顺利进行及试验结果准确度高低的一个重要因素。 ......

气动V型调节球阀--大田球阀

V型调节球阀介绍
V671H(F)气动球阀具有特殊形状的固定式V型切口球体和可调金属阀座结构,当阀关闭时,V型切口与阀座形成楔形剪切作用,可防止球阀球体和阀座之间污物产生的卡死现象,具有自清结功能,特别适用于含纤维料浆,污水和粘性颗粒的介质,配以阀门定位器可实现连续调节,并且流阻小,调节范围广,气动V型球阀是一种用途广泛,高质量的调节阀。

QV47Y型电动V型球阀的特点:
QV47Y型电动球阀的V型切口的球芯与金属阀座之间具有剪切作用,特别适用于含纤维、微小固体颗粒、料浆等介质;
蜗轮传动V型切断球阀还具有调节并可靠定位能力,流量特性为近百分比,可调范围广;
采用板簧加载的可动阀座结构,阀座与球芯不会产生卡阻或脱离等问题,密封可靠,适用寿命长。
