产品详情

一，产品简介：
通信管内壁静摩擦系数测试仪是专业检测仪器，是测量通信管内壁静摩察系数而设计和生产的，具有用性广、测量精度高、测量安全及可靠性好等特点。符合中华人民共和国交通行业标准JT/T496-2004《公路地下通信管道高密度聚乙烯硅芯塑料管》相关技术标准的要求。
the product introduction:
The static friction coefficient tester for the inner wall of the communication tube is a professional testing instrument. It is designed and produced by measuring the static friction coefficient of the inner wall of the communication tube. It has the characteristics of wide application, high measurement accuracy, good measurement safety and good reliability. It meets the requirements of the relevant technical standards of the People's Republic of China transportation industry standard JT/T496-2004 "High-density polyethylene silicon core plastic pipe for highway underground communication pipeline". Technical standards.

三，操作步骤：
♦ 将试样固定在V型铁上，从右端插入试棒使一端露出20mm，拴好链绳。
♦ 轻微摇动手轮使V型铁上水平泡处于水平位置。
♦ 打开角度尺紧固栓，转动角度尺使角度尺与副尺归零，拧紧紧固栓。
♦ 顺时针摇动手轮，使V型铁缓慢倾斜，直至试棒滑动为止。
♦ 记录下角度尺示值。
♦ 逆时针摇动手轮，使V型铁水平为止。
♦ 将试棒拉出通信管外露20mm。
♦ 按照以上操作步骤连续9次，计算出9次平均值。（倾斜角度≤14°4′依据JT/T683-2009《通信管道静摩擦系数测量仪》之规定要求）
Third, the operation steps:
♦ Fix the specimen on the V-shaped iron, insert the test rod from the right end, expose one end to 20mm, and lick the chain.
♦ Slightly shake the handwheel so that the horizontal bubble on the V-shaped iron is in a horizontal position.
♦ Open the angle ruler and turn the angle ruler to zero the angle ruler and the secondary ruler and tighten the fastening bolts.
♦ Shake the handwheel clockwise to slowly tilt the V-shaped iron until the test stick slides.
♦ Record the angle ruler value.
♦ Shake the handwheel counterclockwise to level the V-shaped iron.
♦ Pull the test rod out of the communication tube and expose it to 20mm.
♦ Calculate 9 average values according to the above steps for 9 consecutive times. (The tilt angle ≤14°4' is based on the requirements of JT/T683-2009 "Communication Pipe Static Friction Coefficient Measuring Instrument")
