What are the daily maintenance and maintenance methods of staple fiber spinning testing machine?

The core of daily maintenance of staple fiber spinning testing machine is "regular cleaning, accurate lubrication, parameter monitoring and component inspection", which aims to prolong the service life of the equipment, ensure the stability of test data and avoid sudden failures.

1. Daily maintenance: Focus on basic cleaning and condition inspection.

Equipment cleaning: after the test, clean the residual materials on the surface of the main engine and the melt pipeline in time, and wipe the spinneret with special solvent (such as acetone) to prevent the material from solidifying and blocking the spinneret hole.

Condition check: Before starting the machine, check whether the power supply, air supply and water supply are connected normally, observe whether the indicator light of the control cabinet is abnormal, and test whether the emergency stop button and other safety devices are sensitive.

Parameter record: record the operating parameters of the equipment (such as the temperature of each heating zone, the rotating speed of metering pump and the pressure of cooling air) on the same day, compare the historical data, and find out the deviation in time.

Second, weekly maintenance: focus on component lubrication and functional verification.

Lubrication maintenance: Add special lubricating oil (grease) to the moving parts such as winding machine bearings and cutting machine transmission parts according to the instructions to ensure smooth operation of the parts and reduce wear.

Pipeline inspection: check the tightness of the interface of melt pipeline and cooling air pipeline. If leakage or looseness is found, replace the sealing ring or tighten the interface in time.

Sensor calibration: calibrate the temperature and pressure sensors with standard instruments to ensure that the error of detection data is within the allowable range (usually temperature ≤ 1℃ and pressure ≤±0.01MPa).

Third, monthly maintenance: in-depth inspection of core components and systems.

Inspection of core components: Dismantle and inspect spinneret and metering pump, observe whether the spinneret hole is deformed and whether the gear of metering pump is worn, and repair or replace it in time if there is any problem.

Electrical system inspection: open the control cabinet, clean up the internal dust, check whether the terminal is loose and aging, test the insulation performance of the motor, and avoid short circuit failure.

Maintenance of auxiliary equipment: check the surface smoothness of winding roller, clean up the residual fiber of cutter set, and adjust the alignment of equipment to ensure the smooth running path of fiber.

IV. Long-term maintenance: quarterly/annual in-depth maintenance

Comprehensive disassembly inspection: disassemble the main engine and melt system, thoroughly clean up the internal accumulated materials, check whether the heating pipe and insulation layer are in good condition, and replace the aging seals and pipelines.

Accuracy calibration: contact professionals to calibrate the overall accuracy of the equipment, including the levelness of the main engine, the delivery accuracy of the metering pump and the control accuracy of the winding speed.

Replacement of spare parts: according to the service life of spare parts (such as heating pipes and sensors), replace the parts that are about to be scrapped in advance to avoid sudden failures during the test.
