Produced water jet loom weaving shaft jitter is the cause of abnormal? How to eliminate?

Produced water jet loom weaving shaft jitter is the cause of abnormal? How to eliminate? 2020 - 03 - 20 QiuYu hair water-jet loom in use after a certain number of years, part of the loom weaving shaft in the process of operation will produce abnormal jitter, and domestic loom the situation is more serious, the fluff, easy broken, it can lead to the warp silken face appeared no regularity of rail, pry, led to a decline in production efficiency and product quality. According to the observation of the production situation, found that the main cause of abnormal loom weaving shaft jitter produced have: ( 1) The warp loom tension determine the improper. Especially on the tension is too large, it is easy to cause abnormal weaving shaft jitter. So before production, according to the types of warp, total root number and thickness of thread, to correctly calculate the total required the warp tension, to determine the weight of a heavy hammer, and adjust the tension of stepless transmission pole and diastolic spring tension and make the heavy hammer arm is in a state level. ( 2) Improper let-off triangle tension. Should be in the case of tension meter measuring v-belts, modifying the positions of v belt, make it meet the requirements of theory. ( 3) Weaving shaft axis bearing wear, make its weaving shaft abnormalities resulting from the improper stress shaking. Carefully check should be made for large shaft bearing to see if the wear and tear, and check whether the bearing sleeve wear, if any wear should be timely exchange, and add the lubricating oil in exchange. ( 4) Beam bracket and creel cover wear and tear. If can repair, fair use, then to repair, if can't repair, should change in time, and adjust them to meet the installation requirements. ( 5) Improper let off gear combinations. Because of the mesh is not straight, transmission, and jitter; Should be in accordance with the weft density of fabric measure appropriate gear teeth, and select the correct module to cooperate. ( 6) Gear box oil shortage, damage, corrosion, transmission is not straight and jitter; Should be corrected in time, do not lack of oil, no damage, no corrosion. ( 7) Weaving shaft shaft head is loose and outside channeling, timely repair should be immediately repair, if not timely repair, should be in the machine repaired in a timely manner. ( 8) Weaving shaft bracket tightly capped pin bolt fastening, not completely should be tighten. The above causes of abnormal weaving shaft jitter is likely to be a, may be two, three, the repairman must carefully observe during overhaul, careful analysis, in under the condition of correctly determine the cause, timely give maintenance seriously.
