一,产品简介:
混凝土贯入阻力仪是度盘显示,A力值1000牛顿,用于利用贯入阻力法测定混凝土凝结时间,外型设计轻巧美观。采用杠杆原理,将测针力直接由仪表读数,使试验方便而又准确,混凝土贯入阻力仪适用于各类水泥、外加剂以及不同混凝土配合比,不同气温环境下的混凝土拌合物,凝结时间的试验。
First, the product introduction:
The concrete penetration resistance meter is a dial display with a maximum force of 1000 Newtons. It is used to measure the concrete setting time by the penetration resistance method, and the exterior design is light and beautiful. Using the principle of leverage, the stylus force is directly read by the meter, making the test convenient and accurate. The concrete penetration resistance meter is suitable for all kinds of cement, admixtures and different concrete mix ratios, concrete mixes under different temperature conditions, condensation Time test.

三,操作规程:
★混凝土放于仪器底盘上,松开调节螺套,选装上合适的贯入针。
★旋动调节螺塞使压力表指针对准刻度零线。
★将动作钮子开关置于调整位置,将正反转钮子开关置于正转位置,按工作按钮后试料容器在2秒后。开始上升,待停止以后,即可调整。调整时拧松调节螺套将贯入针调至刚好接触试料面,拧紧调节螺套固定贯入针。再按动动工作按钮,10秒钟以后试料容器升高25mm,即贯入到A深位置,读取压力表贯入阻力并记录,试料容器停留4秒钟以后,开始下降,7秒钟后恢复原位。自动停机,一次测试完成。
★作第二次贯入测试时必须变换贯入位置,推动手柄使其旋转一定角度,当贯入点在外圈时,变化测点只需推动手柄一次;当贯入点在内圈时,变化它则需推动手柄二次。
★在测试过程中,应经常注意压力表指针起始是否在零位,如不在零位应调零。
★在不需调整贯入针高低时,可将动作纽子开关置于自动位置,这样在以后的测试中只要按启动按纽一次,即自动作一次测试循环。
★每个试样作贯入阻力试验应不少于六次,A后一次的单位面积贯入阻力应不少于28MPa。
★使用一段时间后,旋动调节螺塞至极限位置不能使压力表指针调到零线,此时必须添加油液。
Third, the operating procedures:
★ Put the concrete on the instrument chassis, loosen the adjusting screw sleeve, and choose the appropriate penetration needle.
★ Turn the adjustment screw to align the pressure gauge pointer with the zero line of the scale.
★ Place the action toggle switch in the adjustment position, and place the forward/reverse button switch in the forward position. After pressing the work button, the sample container is in 2 seconds. Start to rise, after you stop, you can adjust. When adjusting, loosen the adjusting screw sleeve to adjust the penetration needle to just touch the sample surface, and tighten the adjusting screw sleeve to fix the penetration needle. Press the work button again. After 10 seconds, the sample container is raised 25mm, that is, it penetrates to the deepest position. The pressure gauge is inserted into the resistance and recorded. After the sample container stays for 4 seconds, it starts to fall for 7 seconds. After returning to the original position. Automatic shutdown, one test is completed.
★ For the second penetration test, the penetration position must be changed, and the handle is pushed to rotate a certain angle. When the penetration point is on the outer ring, the change point only needs to push the handle once; when the penetration point is in the inner circle, the change It needs to push the handle twice.
★ During the test, you should always pay attention to whether the pressure gauge pointer starts at zero position. If it is not at zero, it should be zero.
★ When there is no need to adjust the height of the penetration needle, the action button can be placed in the automatic position, so that in the subsequent test, just press the start button once, it will automatically make a test cycle.
★ Each sample shall have a penetration resistance test of not less than six times, and the last penetration resistance per unit area shall be not less than 28 MPa.
★ After using for a period of time, turning the adjusting screw to the limit position does not adjust the gauge pointer to the neutral line. At this time, oil must be added.
