Overview
XH-10T/15T/30T bolt tension meter (drawing instrument) 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 hose. The pump body is made of precision cast steel, with long service life, compact structure, convenient carrying, small size and light weight.
Features
1. The pump body is made of precision cast steel, with a long service life
2. The hydraulic cylinder is hollow self-resetting type, with a lift and can be connected to the high voltage hose through a quick connector
3. The digital pressure gauge reading is intuitive and can directly read the bolt tension (kN) value
4. Compact structure, easy to carry, small size and light weight
5. Hand pump can also be used as a power source for general small Flow rate high voltage oil
Principle
The Working Principle of the bolt tension gauge is: when the center hole of the jack covers the rod to be tested, select a suitable fixture to clamp the part of the rod to be tested that is exposed to the center hole; under the action of the hydraulic force of the pressure pump, the oil pressure is transmitted to the jack cylinder through YouTube, and the piston rod moves outward against the special collet; the pressure acts directly on the anchor shell, and then is transmitted to the clip. After the clip is stressed, the measured rod is clamped, and finally the rod is subjected to an outward pulling force; at this time, the pressure gauge on the pressure pump shows the corresponding force (kN) value, which reflects the size of the pulling force on the measured rod.
Steps
1. Cover the center hole of the jack with the rod under test
2. Select a suitable fixture to clamp the part of the tested rod that is exposed to the center hole
3. Operate the pressure pump to generate hydraulic force
4. Read the force (kN) value displayed by the pressure gauge
5. After the test is completed, remove the anchor manually with less force shaking and vibration
Step 6 Remove the pulling jack
