Overview
RUNJIE RJ-3 miniature drawing instrument is an anchoring force detection instrument suitable for anchors, anchor cables, steel bars, anchor bolts and other anchors. It is the equipment required for mass inspection of anchor construction support projects. The instrument is composed of manual pump, hydraulic cylinder, digital pressure gauge and high voltage hose, anchor, pull rod, adapter, portable box and other parts. The pump body is made of precision cast steel and has a long service life. The hydraulic cylinder is hollow and self-resetting. The digital pressure gauge reads intuitively, can directly read the bolt tension value, and has automatic calculation, backlight, peak holding, storage and query functions. The overall structure is compact, easy to carry, small size and light weight, and 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 RUNJIE RJ-3 miniature drawing instrument provides high voltage oil power through the manual pump to drive the hydraulic cylinder to generate tension, which acts on the anchor rod and other anchoring bodies for anchoring force detection. The digital pressure gauge displays the tension value in real time, and has automatic calculation and peak holding functions to ensure accurate and reliable measurement.
Applications
Anchorage force test of bolt, anchor cable, steel bar, bolt and other anchorage bodies, mass inspection of bolt construction support engineering

Steps
1. Check the oil storage cylinder and oil injection port to ensure sufficient oil
2. Connect high voltage YouTube and quick connector to hydraulic cylinder
3. Install anchors, tie rods and adapters to the tested anchor
4. Operate the pressure handle to pressurize, and observe the tensile force value through the digital pressure gauge
5. After reaching the required tension, use the unloading valve to release the pressure
6. Record or query data, and store or delete it if necessary
Notice
- Check whether the components are firmly connected before use
- Ensure that the manual pump and hydraulic cylinder operate within the rated pressure range
- Regular maintenance of sealing ring and hydraulic system to prevent leakage
Avoid use in extreme temperatures or humid environments
- Pay attention to safety during operation to prevent high voltage oil splashing
When not in use for a long time, remove the battery and store it properly
