=====================================

The hot drawing process uses steam to heat the fiber and then stretch it 4-5 times. It is completed by drawing machine, drawing machine is divided into import and export two parts, equipped with two sets of roller, driven by two asynchronous motor, motor power is 18.5 kw and 5kw, each equipped with two frequency converters for speed adjustment (can be adjusted separately or 2 groups of speed proportional synchronous regulation) . The machine is equipped with a pair of guide rods and two sets of star-shaped rollers. The machine is driven by a 5kw asynchronous motor driven by a long shaft, the tow is formed by dividing the guide rod into two separate sets of star rollers. Pre-drying by curtain dryer, the process is to dry the silk bundles densify, eliminate the inner fiber cavity, so that the structure 2. According to the wet-spinning process, there are two processes: Spinning process and post-processing process. The SPINNING PROCESS INCLUDES: cold-stretching ———— water-washing —— hot-stretching. Dryer by feeding, curtain plate, hydraulic and steam heating four parts. The feeding device introduces the tow into the curtain plate, and the hydraulic device moves left and right (transverse) back and forth, which completes the silk-laying action together with the feeding device, the preformed tow is slowly sent to the steam heating area for drying and densification. The feeding device consists of two inverters to adjust the speed of two 2.2 kw asynchronous motors to drive two pairs of star-shaped rollers to feed the wire beam, and the curtain plate is driven by a inverter to adjust the speed of a 3 kw asynchronous motor. The relaxation link is the link that the formed fiber must be in the state of relaxation and set up in the dryer. In the power supply of the original system, the distribution room of the original system is two-way power supply, but not connected with each other. The main power supply of the circulating water system adopts the 1 # incoming line, the standby power supply adopts the automatic switching device of the incoming line of the power supply, and the standby circuit adopts the 2 # incoming line. Although the two-way power supply is considered, there is no problem on the surface and in theory, and the emergency power and water supply is realized, when the voltage of the 1 # main line is unstable

 曾經(jīng)的歡愉，在街頭的轉(zhuǎn)角已泛黃，回眸，卻已是一地零落的記憶；光影的流年里，山是水的故事，云是風的故事，而你注定不是我的故事；情未央，花已盡，年華里最深的銘記，終是被山水阻隔，化作一縷惆悵，隨風倘佯。
