Volkswagen PV3906 reciprocating wear tester

1、 Purpose:

The reciprocating abrasion tester is used to test the scratch resistance and wear resistance of coatings, plastics, decorative fabrics, automotive interiors, velvet fabrics, and other materials. The LCD screen controls and displays the test process, and can set parameters such as reciprocating wear frequency, motion stroke, and reciprocating speed according to user needs. Unique friction arm design enables the replacement of different friction heads. Implement precise pressure control based on the principle of leverage balance. Fully meet the different requirements of different standards for friction forms, friction heads, pressure, etc.Fabric reciprocating wear testerflat abrasion tester for fabricsMeasure the "wear resistance" of fabrics（486The instrument on the page. It belongs to a type of fabric flat grinder. It is mainly composed of a sports platform, a bracket, etc. Generate linear reciprocating motion through electric motor drive. Install fabric samples on a sports platform with a certain tension. Wrap the bracket with abrasive (e.g400Place the sandpaper on the sample and rub it back and forth. Alternatively, wrap the sample around the support and flatten the abrasive on the motion platform. The bracket and the motion platform undergo relative motion, and the sample is subjected to reciprocating wear on the plane. Measure the changes in weight, light transmittance, strength, or damage of the sample at a certain number of times to determine its wear resistance.

Secondly,Test Principle

The test sample is fixed on a horizontal sample table and worn out as the sample table moves horizontally under the specified abrasive and load. The other end of the test arm is equipped with a weight to maintain its balance and ensure the accuracy of the sample surface load. abrasive

The height of the load rack can be adjusted to suit the testing of samples at different heights.

The instrument consists of the following parts: additional weight, friction head, balance rod, fixed knob, locking knob, and balance weight;LCD screen;power switch;Emergency stop button

Additional weights: Different additional weights are equipped according to various standards and customer needs. After adjusting the balance, the weight of the additional weights is the weight pressed on the sample.

Friction head: There are various types of friction heads available for replacement according to different standards and customer needs. This instrument is equipped with a friction head and its fixture as follows: Among them, forD42 1775During use, the sandpaper should be attached to the curved surface of the grinding head. For rubber grinding heads and sets, the set needs to be disassembled during use. The green grinding head should be placed in the middle of the set, and then the top thread should be used to protrude and tighten it, exposing the surface of the set0.1in.

Fixed knob: Release the fixed knob. If the balance weight and friction head cannot reach balance, the balance rod will tilt. On the contrary, if the fixed knob is locked, even if the balance bar is unbalanced, it can still lock the current position.

Locking knob: After tightening, the front to back ratio of the balance bar can be locked.

Balance bar: It plays a role in measuring whether the lever balance has been achieved and supporting the connection.

Balance weight: According to the principle of lever balance, move the balance weight back and forth to balance with the friction head. Make the pressure of the additional weight equal to the pressure exerted on the actual fabric.

LCD screen: It has the function of setting test parameters, displaying and controlling the test process.

Power switch: Start or turn off the instrument.

Emergency stop button: In case of emergency, press the emergency stop button to shut down the instrument.
