JJFLT Abrasion Performance Tester _Chengde Jinjian Testing Instrument Co., Ltd

JJFLT Abrasion Performance Tester

Is mainly an instrument for testing the abrasion performance of ultra-high molecular weight polyethylene. It is also a necessary testing instrument for factory inspection of such resin product manufacturers, entry inspection of processing enterprises and product comparison test.

1. Same speed in different stations

The instrument is equipped with 6 experimental stations, and one experiment can do 6 samples at the same time. The connection of each station is driven by a synchronous belt, and there is no deviation from the speed of the spindle motor to ensure the consistency of its speed, which greatly improves the comparability of the sample results.

2. Automatic lifting system, high test efficiency and safety

The instrument uses a single capacitor motor to lift and lower the sample rotation system with a chain structure, and can stop at any position during the stroke, which is convenient for observing the installation and status of the sample. Both ends of the lifting system are equipped with double limit positions. Once the first limit position fails, the second limit position is directly triggered to make the instrument in a power-off state. The safety of the instrument is further guaranteed.

3. Design of internal immersion abrasion test cup

During the test, the lid of the test cup is directly pressed into the annular groove of the test cup to prevent the slurry in the cup from overflowing when the sample is rotated. There are three springs on the upper end of the test cup cover to press the cup cover to make the connection between the cup cover and the cup body more firm.

4. Split refrigeration system

It has an immersion cooling method. Below the base panel is an annular water tank. The 6 test cups are immersed in the annular water tank. The temperature of the slurry is controlled by the water in the water tank. In this way, the temperature in the 6 test cups can be changed with the temperature of the water tank, so as to achieve a temperature of 6 cups, and the temperature difference is less than 1 °C, which makes the experimental results more accurate.

5. Rotating sample plate and external suspension stirring design

The handle, stirring shaft, test cup cover, test cup and water tank are all made of stainless steel, which improves the corrosion resistance of the instrument. At the same time, it saves the steps of wiping the instrument before each test and applying anti-rust oil after the test, so that the instrument can be maintained. It's simpler. The rotatable test disk can facilitate the staff to load and unload the sample more conveniently, and rely on the handle to turn the sample disk to turn the station that needs to be replaced to the front of him. The stirring method adopts the external suspension type, which is more convenient to clean the slurry on the sample stirring shaft and replace the sample, which makes the maintenance of the instrument easier.

6. Automatic test, real-time monitoring of sample speed and slurry temperature

The display panel can set the test time (the countdown method is adopted, and the system defaults to 3 hours). After the test, the timing device starts automatically. The display panel can display the current slurry temperature and the number of revolutions of the sample, which simplifies the operation steps and work intensity of the experimenter.
