TLZET-99 Camshaft Eddy Current Flaw Detector

About camshaft:

The camshaft is a component of the piston engine. Its role is to control the opening and closing of the valve. Although the speed of the camshaft is half of the crankshaft in a four-stroke engine (the speed of the camshaft is the same as that of the crankshaft in a two-stroke engine), usually its speed is still high and it needs to withstand a lot of torque, so the design is correct. Camshafts are highly demanding in strength and support, and are generally made of high-quality alloy steel or alloy steel. Since the law of valve motion is related to the power and running characteristics of an engine, the camshaft design plays an important role in the design process of the engine.

Eddy current testing:

Eddy current testing is a method of detecting the surface defects of components and metal materials by using the principle of electromagnetic induction. The detection method is to detect the coil and its classification and structure of the detecting coil. The principle is that an exciting coil is used to generate an eddy current in the conductive member, and the amount of change in the eddy current is measured by the detecting coil, thereby obtaining information on the component defect.

According to the shape of the detection coil, it can be divided into through type (for wire, bar and tube inspection), probe type (for local detection of a component surface) and plug-in (for internal detection of tube hole) Kind.
