Problems solved by technology

When the pipe fabric is used as a conveying pipe or bushing, casing and other products, it needs to be jacketed or lined in the pipe. However, both the jacket and the lining will exert pressure on the pipe wall, which will cause friction when the pipe fabric is pulled out on the pipe wall. hindrance

Abstract

The invention provides a friction coefficient measuring device and a friction coefficient measuring method. The friction coefficient measuring device comprises a supporting outer pipe, an elastic circular ring, a clamp, a tension sensor and a driver, wherein the supporting outer pipe is used for fixing a pipe, a tubular fabric can be arranged on the outer wall of the pipe in a sleeving mode, and the elastic circular ring is used for applying positive pressure to the tubular fabric; one end of the clamp is connected with the tubular fabric, the other end of the clamp is connected with the tension sensor, and the driving end of the driver is connected with the tension sensor. The friction coefficient measuring device can truly reflect the contact state of the tubular fabric and the outer wall of the pipe.

Description

technical field [0001] The invention relates to the technical field of textile measurement, in particular to a friction coefficient measuring device and a method thereof. Background technique [0002] Tubular fabrics made of high-strength fibers, such as aramid fiber, carbon fiber, glass fiber, etc., are widely used in engineering because of their light weight, excellent fatigue resistance, high specific stiffness and specific strength, and good corrosion resistance. basic building blocks. Tubular fabrics are referred to as tube fabrics, which can be used to make various conveying pipes, casings, bushings, high-temperature heat-resistant insulation pipes and other products. The field also has a good application prospect. When the pipe fabric is used as a conveying pipe or bushing, casing and other products, it needs to be jacketed or lined in the pipe. However, both the jacket and the lining will exert pressure on the pipe wall, which will cause friction when the pipe fabr...
