Overview
RUNJIE RJ-VX-3 light puller is a testing instrument composed of manual pump, hollow hydraulic cylinder, digital pressure gauge, high voltage hose, anchor, tie rod, adapter and portable case. Its hydraulic cylinder adopts hollow self-reset and digital integrated design, which can directly read the force value (KN), and has functions such as peak hold, storage, clearing, backlight, inquiry and automatic shutdown. It is technically professional and easy to operate, especially suitable for laboratory and field use.
Features
1. Chinese settings menu
2. Stainless steel body
3. Nickel Plated Pistons and Slides
4. Digital display direct reading force value
5. Peak hold function
6. Surface corrosion resistance electrostatic spray
7.5 segment polyline correction
8. Data storage function
9. High Accuracy Sensor
10. Resistant high voltage sealing ring
11. Automatic shutdown function
12. Self-returning spring
13. Ultra-low power consumption, continuous operation for more than 200 hours
Principle
The instrument provides hydraulic power through a hand pump to drive the piston movement of the hollow hydraulic cylinder. The piston is connected to the anchorage to be tested through a pull rod and an anchor to apply tension. The built-in High Accuracy Sensor detects the force value in real time and displays it directly through a digital pressure gauge. The hydraulic cylinder has a self-reset function and can be automatically returned after the test is completed.
Applications
Testing the pull-out force of various anchors, steel bars (planting bars), expansion bolts, chemical anchors and other anchors, and on-site pull-out force testing of Glass curtain walls (test)
Standards
GB 50203-2011 "Masonry structure engineering construction mass acceptance", JGJ 145-2013 "concrete structure after anchoring technical regulations"
Steps
1. Connect the components of the instrument (manual pump, hydraulic cylinder, high voltage hose, anchor, tie rod, adapter) through quick connector.
2. According to the specifications of the tested anchor, select the appropriate anchor and adapter, and install it on the tie rod.
3. Insert the assembled anchors into the measured anchors (e.g. steel bars, bolts).
4. Open the digital pressure gauge and perform the clearing operation.
5. Operate the manual pump, apply the pulling force smoothly, and observe the change of the digital gauge force value.
6. When the anchorage reaches failure or a predetermined test force value, stop pressurizing, and the digital display will maintain the peak force value.
7. Record or query stored test data.
8. After the test is completed, the pressure of the manual pump is released, and the hydraulic cylinder is returned under the action of the self-return spring.
9. Remove the instrument, clean it and put it in the portable case.
Notice
• Please read the manual carefully before use to ensure that all parts are connected correctly.
• Select the appropriate anchors and adapters according to the specifications of the tested part to ensure that the connection is firm.
• The pressurization process should be smooth and uniform to avoid Impact loads.
• During testing, personnel should stay away from the hydraulic cylinder and the possible ejection direction of the tested part to ensure safety.
• The instrument should be maintained regularly to check the condition of the sealing ring and hydraulic oil.
• Avoid use beyond the instrument range (30KN).
• When storing and transporting, please put the instrument in the portable case to prevent bumping.
• The digital pressure gauge has an automatic shutdown function, please turn it off when not operating for a long time to save power.
