The Alteration About Steam Condensation And Draining System Of Chemical Fiber Stretch Machine

The chemical fiber stretch machine is the key equipment in the entire producing process of polyester fibre. Whether or not it normally works directly relates stability of the producing craft and quality of the product. The surface temperature of roller of HV582 model chemical fiber stretch machine in polyester factory of Tianjin Petrolic Chemical Company is low and instability. It causes the temperature of silk thread not to reach the mark and usually undulate. It results in the influence to the stability of the product quantity. At the same time, it is also the main device of 3.5MPa steam wastage, and the wastage is tremendous. Today, economizing energy sources and reducing wastage become the important contents of the business enterprise management. Alteration of the device with tremendous energy sources wastage is necessarily.The high or low of surface temperature of roller and the big or small of steam wastage is decided by the good or bad of steam condensation and draining system of stretch machine. Thesis just about started with steam condensation and draining system, and it summarized the current draining system, then the existent problem is discussed and analyzed by this thesis. And then craft calculation about common draining system is accomplished, from the measurable side, the existent blemish in the original draining system is Verified. In allusion to the existent blemish in the original draining system, and on the basis of analysis and research, alteration project is brought forward and carried out. For the importance of steam trap in the draining system, the specialized discussion and researches about steam trap is expounded in the thesis.Through the alteration about steam condensation and draining mode of the chemical fiber stretch machine and the betterment about draining pipeline system, and the modern style and multi-function steam trap adopted, so the temperature of silk thread reached the craft request at the exit of stretch machine, the quality of product is ensured. The congealed water inside the rollers is drained in time, the temperature of silk thread by the rollers rised step by step, and producing craft undulation is little and state is steady. Steam heating efficiency heightened, and the press of steam declined to use, so steam wastage reduced. Examine and repair of draining system is more safe and convenient, and the work intensity minished consumedly. The temperature of rollers can be adjusted effectively, so it is propitious to produce various different fibre. In a word, alteration acquired success.This thesis not only solved the existent problem of our device, but also it will bring elicitation and reference to these enterprises which use the chemical fiber stretch machine.
