Laboratory parameters Creep Test Machine
一、要用途及功能
I. Main Purpose and Function
本试验机用于测定混凝土圆柱或长方体度件在恒定的受压荷载作用下，随时间增长的变形，即混凝土的压缩徐变变形。适用于混凝土的恒温和绝湿条件下，测试单向爱压的混凝土徐变试验。本设备的设计、制造完全符合《SL352-2006 》水利行业标准及国家行标准。能满足相关行业的科研院所、大专院校的设计、施工、质检等部门混凝土徐变试验的需要。
This test machine is designed to determine the deformation of concrete cylinder and cuboid parts under constant pressure load over time, namely the creep deformation of concrete, and is applicable for concrete creep deformation test under single-direction pressure at constant temperature in a humid-free environment. The design and manufacture of this equipment complies with water sector standard SL352-2006 and national industry standard and is able to meet the requirements of concrete creep deformation test performed by design, construction and quality inspection departments of scientific research institutions of relevant industries, universities and colleges.
二、主要结构
II. Main Structure
本试验机主要由主机、液压系统、测力单元、压缩变形系统等组成。
This test machine is composed of host equipment, hydraulic system, force measuring unit and compression deformation system etc.
1．主机由顶板、丝杆、中压板、下压板、调节螺母、压板调平总成、叠式弹簧等组成。上下压板间装有活动球座，操作时当上压板底面与试件顶面接触后，能自动适应试件高度方向的细微倾斜，使两平面互相接触全面，从而使软件受力均匀，根据试件大小，可转动调节螺母，上压板自动下降或上升，以适应调节试验空间，上下压板顶面上刻有定位线框，便于将试件放置在中心位置。
1. The host equipment is composed of top board, screw rod, middle compression plate, lower compression plate, adjusting nut, compression plate leveling assembly and folded spring etc. A movable ball base is mounted between upper and lower compression plates. During the operation, when the bottom surface of upper compression plate is in contact with top surface of test piece, it will automatically adapt to the slight tilt in height direction of test piece, enabling the two planes contact in large area for uniform stress distribution. The upper compression plate will descend or rise automatically by rotating the adjusting nut according to the size of test piece so as to adapt to the test space. The top surface of upper and lower compression plates is carved with positioning frame for the convenience of placement of test piece at the center.
2．液压系统（需用户另购）
2. Hydraulic System (option)
由手动或电动液压泵、油管及分离式油压千斤顶组成。此液压系统每套可控制多台徐变试验机，为一台加压到额定的压力后调节徐变试验机的锁定螺母固定后可移到另一台机器进行工作。
Composed of auto or manual hydraulic pump, oil pipe and split hydraulic jack, each set of this hydraulic system can control several creep deformation test machines. The creep deformation test machine of which the pressure has been increased to rated level can be moved to another machine by adjusting the fixing nuts.
3．测力单元
3. Force Measuring Unit
主要由压力传感器，连接线及高精度数显仪表组成。
This unit is mainly composed of pressure sensor, connection line and high-accuracy digital instrument.
三、产品特点
III. Product Features
1．本徐变试验机****优点运输方便，可散装运输，现场安装调试。
1. This creep deformation test machine features convenient transportation, bulk transport and on-site installation and debugging.
2．本徐变试验机加压到额定压力后，固定调节螺母，数显仪表显示当前的压力，试件长时间加压变形压力不足额定压力时，人工开动液压系统开始加压到额定压力紧固调节螺母。
2. After the pressure of this test machine is increased to rated level and the adjusting nuts are fixed, the digital instrument will indicate the current pressure. In case the long-term compression deformation pressure is lower than rated pressure, the hydraulic system shall be manually operated to increase the pressure to rated level and to fasten the adjusting nuts.
3．本徐变试验机如试验繁忙每台可同时做2个试件可节约投资。
3. Each of this creep deformation test machine can perform test on two test pieces at the same time in case the test process is busy, so as to reduce the investment.
