Overview
RUNJIE RJ-1 miniature drawing instrument is a bolt tension gauge, which is suitable for the detection of the anchoring force of anchors, anchor cables, steel bars, anchors and other anchors. It is one of the instruments required for mass inspection of bolt construction support engineering. The instrument is composed of a manual pump, a hydraulic cylinder, a digital pressure gauge, high voltage hoses, anchors, pull rods, adapters, portable cases and other parts. The structure is compact, easy to carry, small size and light weight. The manual pump can also be used as a power source for general small Flow rate high voltage oil.
Features
1. Nickel Plated Pistons and Slides
2. With Data storage function, 100 Data storage capacity
3. Surface corrosion electrostatic spray
4. New sealing ring, reliable work
5. Instrument data query and deletion
6. Automatic spring return, simple structure
7. Automatic shutdown function
8. Peak hold function
Principle
The RJ-1 bolt tension gauge generates high voltage oil through the manual pump, which is transmitted to the hydraulic cylinder through the high voltage hose to drive the piston to generate tension. The digital pressure gauge directly reads the bolt tension value, and has automatic calculation, backlight, peak holding, storage and query functions. The hydraulic cylinder is hollow and self-reset, and the operation is simple and reliable.
Applications
Anchorage force test of bolt, anchor cable, steel bar, bolt and other anchorage bodies, mass inspection of bolt construction support engineering
Standards
GB 50367-2006、GB 50330-2002、GB 50086-2011、GB 50007-2011、CECS 22：2005、CECS 22:99、JGJ 120-2012、JGJ 145-2013
Steps
1. Check whether the components of the instrument are firmly connected
2. Install the anchors, pull rods, and adapters on the tested anchors
3. Connect high voltage YouTube and quick connector
4. Operate the manual pump pressure handle and gradually pressurize
5. Observe the digital pressure gauge reading and record the peak tension value
6. After the test is completed, open the unloading valve to relieve pressure
7. Disassemble the instrument, clean it and store it
Notice
• Check whether the components are in good condition before use to ensure no leakage
• Avoid overpressure during operation to prevent damage to the instrument
• Regularly check the battery level to ensure that the digital pressure gauge is working properly
• Release pressure in time after test to avoid long-term pressure
Keep drying during storage to prevent corrosion
• Follow relevant safety regulations to ensure the safety of operators
