Overview
The intelligent bolt puller is composed of a manual pump, a hollow hydraulic cylinder, an intelligent digital pressure gauge, a high voltage YouTube and options, and is integrated into the Portable system. It adopts an imported Sensor with high Sensitivity and accurate value, which can directly read the tensile force value, and has functions such as automatic calculation, peak holding, storage query and backlight display. The hollow hydraulic cylinder is equipped with a dust protection system and an imported sealing ring, which has a long service life and simple operation. It is especially suitable for laboratory and field use.
Features
1. Imported Sensor with High Sensitivity and Accurate Value.
2. An integrated multi-function display instrument that can directly read tensile force values (kN, Mpa).
3. Equipped with automatic calculation, peak hold, storage and query functions.
4. With backlight display, easy to use in poor ray of light environment.
5. The hollow hydraulic cylinder is equipped with a dust-proof system and an imported sealing ring, which has a long service life.
6. Easy to operate, easy to learn and use, suitable for laboratory and field use.
7. Equipped with a portable carrying case for easy portability and storage.
Principle
The instrument is pressurized by manual pump, and the hydraulic oil is transported to the hollow hydraulic cylinder through the high voltage YouTube to push the piston to generate tension. The tension acts on the measured anchors (such as bolts, steel bars, etc.), and the force value is detected in real time by the pressure sensor in the hydraulic cylinder and transmitted to the intelligent digital pressure gauge for display, calculation and storage, so as to realize the accurate measurement of the pull-out force of the anchors.
Applications
It is suitable for testing the pull-out force of various anchors, steel bars (planting bars), expansion bolts, chemical anchors and other anchors, and can also be used for on-site pull-out force testing (test) of Glass curtain walls.
Standards
GB 50367-2013 "Code for Design of Reinforcement of Concrete Structures", GB 50330-2013 "Technical Specifications for Building Slope Engineering", JGJ 120-2012 "Technical Specifications for Building Foundation Pit Support", CECS 22:2005 "Technical Specifications for Geotechnical Anchors (Cables) ", GB 50001-2011 "Code for Design of Building Foundation", JGJ 145-2013 "Technical Specifications for Rear Anchorage of Concrete Structures", GB 50550-2010 "Code for Construction Mass Acceptance of Building Structure Reinforcement Engineering", GB 50203-2011 "Code for Construction Mass Acceptance of Masonry Structure Engineering"
Steps
1. Remove the instrument from the portable case and check whether the components are in good condition.
2. According to the type of anchor to be tested, select the appropriate anchor, adapter and tie rod for assembly.
3. Connect high voltage YouTube, hand pump and hollow hydraulic cylinder through quick connector.
4. Turn on the intelligent digital pressure gauge and make necessary parameter settings (such as unit selection).
5. Sleeve the assembled hydraulic cylinder and anchor on the tested anchor.
6. Operate the manual pump to apply pressure slowly and evenly, and observe the pressure change on the digital display.
7. When the test requirements are met or the anchors are displaced, the digital display will maintain the peak pressure.
8. Record or store test data.
9. After the test is completed, manually reset the hydraulic cylinder piston.
10. Remove the connection, clean the parts and put them back in the portable case.
Notice
Please read the instructions carefully before use and ensure that the operator is trained.
Make sure that all connection parts (especially quick connectors) are firmly connected and leak-free.
* The pressurization process should be smooth and slow to avoid Impact loads.
Do not exceed the maximum range of the instrument (500KN).
During testing, personnel should stay away from the hydraulic cylinder and the direction where the tested part may be ejected to ensure safety.
Regularly check the amount of hydraulic oil and the cleanliness of the oil, and replace or replace it if necessary.
* When the instrument is not in use, the power should be turned off and stored in a drying, non-corrosive gas environment.
When the instrument malfunctions, do not disassemble it yourself. You should contact a professional for repair.
* This product is guaranteed for one year and implements a lifetime maintenance responsibility system.
