How much is the domestic concrete abrasion resistance testing machine

1Overview

The measuring instrument for concrete abrasion resistance testing machine is based on the "Test Code for Hydraulic Concrete"DL/T5150-2001》According to the specified technical requirements, a test is designed to use rotating water flow to impact steel balls and form steel ball impact wear on the surface of precast concrete, in order to determine the ability of various concrete surfaces to resist water flow impact wear.

2、 Main technical parameters

1. Sample size: φ300×100mm

2. Sample container barrel size: φ302×430mm

3. Motor stirring speed:1200r/min

4. Steel ball diameter: φ12.7mm；φ19.1mm;φ25.4mm25a

5. power supplyAC 380V 50HZ

6. Power:1.5KW

7. volume1800 mm×800mm×500mm

8. Weight:180kg

3、 Structural principle

It consists of a frame, an electromagnetic speed regulating motor, a pulley worktable, a test container, a water flow stirrer, a sample forming cylinder, etc.

When the motor is working, the main shaft equipped with a stirrer is driven to rotate by a speed regulating motor. The stirrer is installed in the sample container, and rolling steel balls of different specifications are placed on the surface of the sample. The stirrer is partially immersed in water, and according to1200r/minRotate and stir the steel ball at a certain speed to generate friction and wear on the sample, in order to verify the anti wear ability of the concrete surface.
