The application of encoder on the TBM！

Rotary encoders are indispensable speed and angle measurement feedback sensors in today's industrial production. Encoders are widely used in various industries in China, making all kinds of advanced machines made in China even more powerful.

Shield tunneling machine, referred to as shield machine. It is a special engineering machine for tunneling. The modern shield tunneling machine integrates light, machine, electricity, liquid, sensing, information technology as a whole. It has excavation and cutting soil, conveying soil, assembling tunnel lining, measuring and guiding correction. And other functions, involving geology, civil engineering, mechanics, mechanics, hydraulics, electrical, control, measurement and other disciplines, but also in accordance with different geology to "tailor-made" design and manufacturing, reliability requirements are extremely high. Shield tunneling machines have been widely used in subway, railway, highway, municipal, hydropower and other tunnel projects.

The encoder is used in the pipe erector, an important component of the shield machine. Encoder installed on the equipment, in order to control the rotation Angle of information system to provide the equipment, so as to control system accurately controls the rotation angle of the device according to the position information provided by the encoder, at the same time to limits the device to prevent the device from rotating. Excessive damage to the device body or other hazards
