Under normal circumstances, the hot air stenter device cannot be operated on the same type of door frame for a long period but should be replaced with a different type of door frame at regular intervals. This prevents premature wear of the splined spindle. In daily work, the operator also needs to frequently check whether each travel switch of the hot air stenter equipment is sensitive and effective.
If any damage is found during the inspection, it should be replaced in time. The amplitude modulation screw inside the drying room of hot air stenter equipment also needs to be cleaned frequently, generally once a month. If the equipment used is of oil heating type, the filter on the heat-carrying oil pipeline should be removed for cleaning at least every six months. You can continue to use it after cleaning up.
If during the daily use of the hot air stenter equipment, it is found that the oil pressure has decreased, or the temperature has risen slowly, it may be due to the clogging of the filter, which should be checked and handled in time. If it is electric heating, you need to check whether the electric heating tube has abnormal problems. If the current does not flow, it should be replaced in time.
Under normal circumstances, when the hot air stenter equipment is used continuously for seven days, the filter should be cleaned to remove the attached fluff. Also, the hot air circulation system should be cleaned regularly, especially the spray pipe needs to be cleaned once a month. As for the exhaust fan and exhaust ducts, they are generally inspected and cleaned every 3 to 6 months to avoid accidents.
In addition to the content described above, the needle clip and needle plate of the hot air stenter should also be cleaned regularly, usually once a week. At the same time, it is necessary to clean the oil in the oil pan above the exhaust duct once a week.
