Operation concrete test instrument to use is very important, if errors in operation will give you cause unnecessary trouble, as well as strict control of the use of its unique structure, twin concrete test equipment with high mixing efficiency, more uniform mixing thereof, Stripper cleaner and so on. Here there are a few steps to use concrete testing equipment: for construction-related scientific research, design departments and laboratories and construction unit used to measure the deformation of shrinkage and expansion of concrete. Shrinkage of concrete expansion instrument from the base, positioning column, adjustable column, dial indicator, par and so on. 1, the base for the steel unit, for receiving the test block with concrete. 2, positioning column for par and concrete brick probe on the left side of the vertical and horizontal spacing. 3, adjustable column, its commercial port there are three pre-installed through holes dial indicator dial indicator positioning and help set screws. Three through holes respectively from the base plane 50mm, 75mm, 100mm 50mm from the base datum hole for measuring 100 × 100 × 515 specifications of concrete brick; 75mm holes from the base plane, test instruments for measuring 150 × 150 × 515 specifications of concrete brick (due tryout specification only 150 × 150 × 600, should Proposed Use tryout shorten pieces so concrete brick forming size becomes 150 × 150 × 515). 4, par, Henan standard curing chamber test instrument, as the instrument of reference length. The factory has been installed on par par shelf, do not free entry, so as not to affect the degree of accuracy par Center. 50,75100 words each side of par, Henan carbonation tank testing equipment, such as showing where on the base reference plane, the standard rush Center 9 height respectively 50mm, 75mm, 100mm. Concrete Test Hammer maintenance of concrete back There should be one bomb instrument for routine maintenance of the following conditions: 1. The shells hit more than 2,000 times; 2. detection values ??are suspected; 3. Steel anvil rate setting failure; routine maintenance shall conform to the following requirements: 1. Make hammer shells removed after decoupling movement, test equipment Henan curing room, and then remove the fillip bar (remove the inside cushion spring) and FRL (hammer shells, shells hit extension spring and extension spring seat); 2. each movement with gasoline to clean parts, especially in the center of the hole and the impact surface guide rod, playing the hammer and the fillip bar. After washing in the center of the guide rod coated with a thin layer of oil or sewing machine oil clocks, other parts shall be oiled; 3. Clean the casing wall, remove the scales, to check that the friction force should be 0.5-0.8N Room; 4. shall rotating end cap positioned fastening screws zero; 5. Do not make or replacement parts; 6. After maintenance should be required to carry out calibration test, calibration value should be 80 ± 2.
