Overview
XH-3T bolt tension meter (drawing instrument) is produced by Tiandi Spark brand, 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 anchor construction support projects. The tension meter is composed of manual pump, hydraulic cylinder, digital pressure gauge and high voltage rubber pipe. The pump body is made of precision cast steel, which has a long service life. The hydraulic cylinder is hollow self-reset type, with a lift and connected through a quick connector. The digital pressure gauge reading can directly read the bolt tension value. The structure is compact, easy to carry, small size and light weight.
Features
1. Suitable for a variety of anchorage inspections, including bolts, anchor cables, steel bars, anchor bolts, etc
2. Adopt precision cast steel pump body for long service life
3. Hollow self-resetting hydraulic cylinder with handle for easy operation
4. The digital pressure gauge intuitively displays the tension value, which can directly read the bolt tension (kN).
5. Compact structure, easy to carry, small size and light weight
6. Hand pump can be used as a power source for general small Flow rate high voltage oil
Principle
The Working Principle of the bolt tension gauge is: after the center hole of the jack covers the tested rod, the exposed part of the rod is clamped with a fixture; under the hydraulic action of the pressure pump, the oil pressure is transmitted to the jack cylinder through YouTube, and the piston rod moves outward against the special chuck; the pressure acts on the anchor shell and is transmitted to the clip clamping rod, so that the rod is subject to the outward pulling force; the pressure gauge shows the corresponding force (kN) value, reflecting the pull force on the rod. If the rod is a steel bar, the anchoring force of the steel bar can be measured. After testing, manual shaking and vibration are required to remove the anchor, which is convenient for removing the jack.
