Main Product Features

1. The entire test is automatically controlled and tested by the instrument, eliminating various human errors.

2. It has an overpressure automatic protection function. When overpressure occurs, the window displays 99.99, and the instrument automatically stops pressurizing, preventing damage to the instrument due to overpressure.

3. Test results and time can be printed.

4. Loading and unloading of the instrument are automatically controlled by the instrument.

5. The display uses a dedicated chip, eliminating flickering during the test.

Main Technical Parameters:

1. Pressure measurement range: 0-50.00KN

2. Flow value measurement range: 0-150.0 (0.1mm)

Top of Form 3. Upper and lower pressure heads: Inner diameter 101.6mm (standard type)

Inner diameter: 152.4 mm (large type)

4 Can store 25 test data for specimens; data is not lost after power failure.

5 Operating voltage: 220V ± 10% 50HZ Power: 550W

6 Operating temperature: 10-30 ℃ Operating temperature guarantee: 5-35 ℃

7. Dimensions: 60 × 38 × 84cm

LHSL-326E Expansion Joint Rubber Seal Strip Clamping Performance Testing Machine

The Microcomputer Controlled Electronic Tensile Testing Machine, specifically designed by Beijing Lanhang Zhongke Measurement and Control Technology Research Institute for rubber sealing strips in highway bridge expansion joints. The computer system, through a fully digital controller, controls the rotation of a high-precision stepping motor via a speed control system. After deceleration by the deceleration system, it drives the movement of the moving crossbeam via a precision ball screw pair, completing the repeated tensile mechanical performance test of the sample. It is suitable for rubber sealing strip performance testing in highway bridges and other applications. The equipment meets the requirements of JT/T326-2016 "General Technical Conditions for Highway Bridge Expansion Joints".
