Fixed length deceleration, fixed length parking, forward and reverse rotation functions, static electricity elimination function
A first winding roller (11) and a second winding roller (13) with a limited roller gap (15), wherein the core is inserted through this roller gap and the material (N) is fed through this roller gap; Engage with at least one pair of movable connectors (57) to engage with the end of the winding core and transmit rotational motion to the core during at least a portion of the winding cycle of the package. Manufacturing and arranging the joint components and the first and second winding rollers in this way, so that the formed package comes into contact with the first and second winding rollers; In addition, a third winding roller (17) is also provided, which limits the winding space together with the first and second winding rollers. The third winding roller is movable to allow each packaged winding to increase and complete within the winding space. Flow instruments are widely used in process control, and their role in process control is to detect the fluid flow in the sealed pipeline. If necessary, flow measuring instruments and regulating instruments are also used The actuator and other components form a regulating system to stabilize the flow within an appropriate range, thereby achieving process stability. Therefore, flow measurement instruments need to meet the requirements of stable performance, reliability, strong anti-interference ability, short impact time, and diversity of output signals in process control. Below, we will explore the application of flow meters in oilfield automation measurement systems and boiler air supply processes in power plant process systems to gain a specific understanding of the use of flow detection and flow instruments.
