本机是“用促凝压蒸技术一小时推定混凝土强度试验方法”的专用设备之一,用于混凝土湿筛砂浆的筛分及试件的成型,也可作为某些采取混凝土湿筛砂浆进行性能试验(例如混凝土凝结时间)时的设备。本机系用0.5千瓦电动机带动双凸盘形凸轮,由弹簧的反压复位作用,使从动件进 This machine is one of special equipments for “Testing Concrete Strength Test Method with One Hour of Promoting Condensing Pressing and Steaming Technology”. It is used for the screening of concrete wet sieve mortar and the forming of test pieces, and it can also be used as some concrete wet sieve mortar. Equipment for performance testing (eg concrete setting time). This machine uses a 0.5 kW motor to drive a double-convex disc cam, which is reset by the spring’s back pressure to move the follower.
