Overview
Subgrade pavement bonding performance tester (model: KS-L5, brand: KOSON) is mainly used to detect the bonding performance of subgrade pavement. The instrument consists of a miniature ultra-light small manual pump, a small hollow self-resetting hydraulic cylinder, a digital pressure gauge, a high voltage YouTube (2.5 meters) with a quick connector, a portable instrument case, a reaction frame, a tie rod and a 100mm marker block. The numerical display part is an integrated multi-function display instrument, which can directly read the tensile force value (kN), and has automatic calculation, peak holding, storage and query functions, with backlit display.
Features
1. Light weight, 2.6kg cylinder, 2.8kg small manual pump.
2. Equipped with 50 data recording, query, and LCD lighting functions.
3. Support peak hold and automatic shutdown without operation.
4, the value of 10 segment line correction, improve instrument accuracy.
5. Power supply is high-capacity rechargeable lithium battery, ultra-low power consumption design, Continuous Operating Time can exceed 200 hours.
6, using imported sealing ring, durable.
7, hydraulic cylinder surface corrosion resistance electrostatic spraying, nickel-plated piston and sliding sleeve.
8. With an overload protection structure, the cylinder will not be damaged beyond the range.
Principle
The tester generates tension by driving a small hollow self-resetting hydraulic cylinder through a micro-manual pump, and the tension is transmitted to the bonding of the road surface to be tested through the reaction frame and the tie rod. The tension value is displayed and recorded in real time by the digital pressure gauge, and the meter has the function of automatic calculation and peak hold to evaluate the bonding performance of the roadbed and pavement.
Applications
Subgrade pavement bonding performance detection
Steps
1. Connect the components of the instrument (manual pump, hydraulic cylinder, high voltage YouTube, reaction frame, tie rod and standard block).
2. Fix the reaction frame and tie rod at the position of the road surface to be tested.
3. Turn on the power supply of the digital display instrument.
4. Operate the manual pump to make the hydraulic cylinder apply tension smoothly.
5. By observing and recording the tensile force value through the meter, the meter can automatically maintain the peak value.
6. After the test is completed, release the pressure and reset the hydraulic cylinder.
7. Query or store test data through the meter.
Notice
• Please check whether the components are firmly connected before use.
• Please ensure that the reaction frame is installed stably during operation.
Do not exceed the maximum measurement range of the instrument (0-50KN).
• The instrument has overload protection, but it is still necessary to avoid overloading for a long time.
• Regularly check the battery level to ensure continuous testing.
• The instrument is stored in a drying environment to avoid corrosion.
• Please follow the operation steps to use the instrument.
