四,DT-20W混凝土动弹仪使用方法

★首先根据试件尺寸,调整好两下刀口距离。

若试件尺寸为100×100时,应首先将固紧螺母(13)拧紧,把右连接扳(12)与两只25mm长的定位套(14)调换位置(即将连接扳放在两只定位套的里面),然后将固紧螺母拧紧。

若试件尺寸为125×125时,应将固紧螺母拧松,把右连接扳放在两只25mm定位套中间,然后把固紧螺母拧紧。

若试件尺寸为150×150时,侧将右连接扳放在两只25mm定位套的外边即可,如结构示意图所示。

★在左、右基座(17)(19)上,装好左、右标尺(2)、(7),并将紧定螺钉拧紧,固定好标尺。

★调整上刀口位置,使上、下刀口(6)(11)间距等于所需距值,然后将固紧螺钉(5)拧紧。

★将两只配用量表(1)、(8)左右编号后分别装在左,右基座上,位置按触,

★双手握住左、右连接扳(16)(12)均匀地压缩的位置上,如兼弹簧夹紧力不够,可转动调节螺母(21)调整弹簧压力。

★在测压缩变形时,仪器在夹持试件后,将定位螺钉(9)下旋离开下刀口底面〉7mm(做完试验后再复位,使下刀口底面成水平位置)

在测拉伸变形时,侧不需要将定位螺钉下旋,仍保持下刀底面成水平位置接触。

★为了增强上刀口的夹紧力也可通过手轮(4)调整。

★试件在标距范围内的压缩量取两表数值的平均值进行计算。

Fourth, the use of concrete dynamic modulus tester:
★ First adjust the distance between the two cutting edges according to the size of the test piece.
If the size of the test piece is 100×100, first tighten the tightening nut (13), and change the position of the right connecting plate (12) and the two 25mm long positioning sleeves (14). Inside the sleeve), then tighten the tightening nut.
If the size of the test piece is 125×125, loosen the tightening nut, place the right connecting plate between the two 25mm positioning sleeves, and then tighten the tightening nut.
If the size of the test piece is 150×150, the right side of the test piece can be placed outside the two 25mm positioning sleeves, as shown in the structural diagram.
★ On the left and right bases (17) (19), install the left and right scales (2), (7), and tighten the set screws to fix the scale.
★ Adjust the position of the upper knife edge so that the distance between the upper and lower knife edges (6) (11) is equal to the required distance, and then tighten the fastening screw (5).

★The two metering tables (1) and (8) are numbered and placed on the left and right bases respectively.
★ Hold the left and right connecting plates (16) (12) with both hands in a position where the clamping force is evenly compressed. If the clamping force of the spring is not enough, turn the adjusting nut (21) to adjust the spring pressure.
★When measuring the compression deformation, after clamping the test piece, the instrument will rotate the positioning screw (9) off the bottom surface of the lower knife edge > 7mm (reset after the test, so that the bottom surface of the lower knife edge is horizontal)
When measuring the tensile deformation, the side does not need to rotate the positioning screw down, and still keep the bottom surface of the lower knife in a horizontal position.
★ In order to enhance the clamping force of the upper knife edge, it can also be adjusted by the handwheel (4).

 

五,DT-20W混凝土动弹仪产品特点:

★手动测量频率灵敏度达到了1Hz,从100HZ到20KHZ可实行跳频扫(即以十位百位千位或万位粗扫),精扫(粗扫到值后再以更精确的位数细扫,直至精确到1HZ)。

★自带内存:可存储100次试验数据,数据导出集中打印等。

★进口编码开关 ,一键式操作:原装进口ALPS编码开关具有操作手感好,使用寿命长等特点,独创的一键全能操作功能,配合全中文操作提示菜单,让您轻松操控设备,简单清晰、一目了然。

★热敏打印机,经济低噪:本机采用新型热敏打印机,比传统的针式打印机出纸速度快、噪声小,且打印品质高运行稳定,使用中只需换纸无需更换碳带,同时软件可设置成省纸状态,或集中打印。

Five, concrete dynamic modulus tester Features:
★ Manual measurement frequency sensitivity reaches 1Hz, from 100HZ to 20KHZ can perform frequency hopping sweep (that is, tens of thousands of thousands or 10,000 bits of rough sweep), fine sweep (thick sweep to the value and then more precise digits Sweep until it is accurate to 1HZ).
★ Comes with memory: It can store 100 test data, and the data is exported and printed.
★Imported code switch, one-button operation: Original imported ALPS code switch has the characteristics of good operation feel, long service life, etc. The original one-button all-round operation function, with the full Chinese operation prompt menu, allows you to easily control the equipment, simple and clear, At a glance.
★ Thermal printer, low noise: This machine adopts a new thermal printer, which has faster paper output, lower noise than traditional needle printer, high print quality and stable operation. It only needs to change paper during use without replacing the ribbon. The software can be set to save paper or concentrate printing.
★Improved metal probe, fine and beautiful: The external use of electroplating technology makes the probe have shiny luster and more dynamic; the precise magnetic circuit and sound path design make the probe more sensitive and repeatable testability. At the same time, it has high impact resistance, making it sturdy and durable, achieving a perfect blend of visual experience and function.
