A method for repairing the oil leakage of the oil delivery pipe of the spinning finish pump on-line

Abstract

The invention discloses a method for repairing the oil leakage of the oil delivery pipe of the spinning oil agent pump on-line. Step 1: placing a container containing the oil agent transported by the oil leakage plastic oil pipe to be repaired under the oil leakage of the plastic oil pipe; Step 2: Mark the leak or damage of the plastic oil pipe; Step 3: Submerge the leak or damage of the plastic oil pipe in the container so that the leak or damage of the plastic oil pipe is below the oil level, and then use a cutting tool Cut off the plastic oil pipe with leakage or damage along the mark of oil leakage under the oil liquid surface. The method for on-line repairing of the oil leakage of the oil delivery pipe of the spinning oil pump realizes on-line repair of cracks without stopping the station or production, and without affecting normal production and product quality.

Description

Technical field: [0001] The invention relates to the field of polyester filament production, in particular to a method for repairing the oil leakage of an oil delivery pipe of a spinning oil pump on-line. Background technique: [0002] In the process of polyester filament production and processing, in order to improve spinnability and benefit post-processing weaving or texturing, the filament fiber will be oiled. The basic process of the above method is: oil storage oil balance tank-- Oil pipeline--oil pump--oil injector--filament fiber oiling. The oil delivery pipes used in the industry are all plastic pipes. Generally, the diameter of the pipes is in the range of 2-10mm. With the extension of the use time, the plastic pipes will age or be cracked by external forces, resulting in oil leakage or air in the pipes. It is easy to cause online spinning. Fibers with little or no oil will result in poor spinnability and unstable post-processing performance. Generally, when the o...

Problems solved by technology

The oil delivery pipes used in the industry are all plastic pipes. Generally, the diameter of the pipes is in the range of 2-10mm. With the extension of use time, the plastic pipes will age or be cracked by external forces, resulting in oil leakage or air in the pipes, which is easy to cause online spinning. The fiber has less oil or no oil, resulting in poor spinnability and unstable post-processing performance

Generally, when cracks are found in the oil pipe, it is necessary to stop the production spindle equipment and deal with it again. Although the problem can be solved in this way, the loss caused by the stoppage of production is relatively large.
