The maintenance of the Eugen yarn puffing machine can start from daily inspection, regular maintenance, maintenance of key components, replacement of vulnerable parts, lubrication management, electrical system maintenance, etc. The following is a detailed introduction:
Daily inspection
Transmission parts: Check whether the sound of the transmission parts in the front and rear transmission boxes is normal, and whether the synchronous belt runs off.
Bearings and components: Check whether the bearings at each roller component, friction roller component, guide wire and transmission component are heating and vibrating;
; Are there any scratches on the leather roller; Is the rotation of the false twisting device, tube holder clamp, and leather roller flexible.Elastic coupling: Each time the machine is stopped, the elastic coupling of each part must be checked for looseness or wear. If there is looseness, it must be tightened, and if there is wear, it must be replaced.
.Synchronous belt: The operation of the synchronous belt must be checked daily to observe for looseness, missing teeth, and friction between the synchronous belts.
.Regular maintenance
Minor maintenance: usually carried out every 2-5 weeks, focusing on cleaning equipment hygiene and removing dust from various parts of the machine;
; Remove waste wires from rollers, friction rollers, shafts, wire guides, and false twists; Check the damage of various operating parts and wire guides; Remove dirt and other debris from the upper and lower hot box guide wires and other threads.Major maintenance: Generally, it is carried out every 1-3 months. In addition to minor maintenance, check the cleanliness and wear of the synchronous belt and synchronous pulley in the transmission part.
; Open the wear condition of the groove tube, shuttle, slider, etc., and determine whether to replace them; Check the lubrication condition of the groove cylinder; Check the bearings and lubrication conditions at all locations; Check the cleanliness of the cold rail and the toothed belt of the false twisting device; The rotational flexibility of the leather ring wheel, etc.Maintenance of key components
Hot box maintenance: When the filament passes through the hot box tube, the spinning oil agent is heated and evaporated, and a small part of the components with lower boiling points remain in the heat pipe, forming dirt and coking, which will affect the heating effect of the filament and cause a decrease in the quality of DTY, so it should be cleaned regularly.
. The cleaning cycle depends on the fineness of the processing wire, the operating speed of the machine, and the type and content of POY oil, usually 2-3 months. Regularly clean the guide wire tubes in the first and second hot boxes, rotate the hot box to an inclined position, extract the tubes from above, immerse them in 15% -20% alkali solution and heat them, cool them down, remove them, wash them clean with hot water, and then dry them with compressed air to check if the dirt inside the tubes has been cleaned. When cleaning pipes, be careful not to make the pipe mouth or inner wall rough or deflate.Leather roller maintenance: The first and second roller leather rollers are usually polished once after 1-3 months of use, and the third roller leather roller is polished once after about 6 months of use. During polishing, check whether the bearing rotates flexibly.
.Friction false twisting device maintenance: It is necessary to promptly remove the waste threads wrapped around the friction spindle shaft and the "snowflakes" on the friction disc.
. When abnormal rotation speed of the friction disc, misalignment of false twisting tension (confirmed to be caused by the friction false twisting device), and difficulty in generating heads are found, the friction false twisting device should be removed for inspection. Check whether the small bearings of the false twisting device are damaged and whether they rotate flexibly, as well as whether the small toothed belts that drive the three spindle shafts are stretched or worn. If any abnormalities are found, they should be replaced in a timely manner. The surface of the friction disc should also be inspected regularly. If peeling, scratching, roughness, or other phenomena are found on the surface, they must be replaced in a timely manner.Replacement of vulnerable parts
Leather ring: Replace the leather ring once every 1 month to 45 days in conjunction with maintenance dates.
. Replace the first roller leather ring with a new one, clean the original first roller leather ring and replace it with a second roller leather ring, clean the original second roller leather ring and replace it with a third roller leather ring, and discard the original third roller leather ring. Rabbit head and small shuttle: Replace according to wear and tear within 6-12 months.Head rod guide: Rotate the head rod guide by 120 ° according to the degree of wear for 12 months, and replace it after 360 ° rotation.
.PU disk: Replace according to the degree of wear and tear after 24 months.
.Leather ring wheel 608 bearing and chuck bearing: Replace the first and second roller leather ring wheel 608 bearings and chuck bearings uniformly in about 24 months.
.Transmission synchronous belt: usually replaced every 12-18 months.
. Lubrication ManagementFalse Twist Ingot Group and Its Auxiliary Mechanisms: The false twist ingot group and its auxiliary mechanisms have the highest operating speed and lubrication requirements on the feeding machine.
. The three shafts of the false twisting device must be filled with imported high-temperature and wear-resistant grease (the industry default is German Krupp NBU15 fully synthetic high-speed grease), and the base dragon belt supporting wheel, supporting wheel, and limit wheel can be filled with general domestic high-temperature resistant grease. If ceramic discs are used, the false twisting machine shaft speed is higher, with a cycle of generally 12 months. If PU discs are used, the speed will be reduced by about 25%, and the cycle can be extended to about 18 months.Horizontal box: The horizontal box has two stages: refueling and oil change. After running the new machine for a period of time, 50% of the oil is added from the bottom of the horizontal box (the industry default is BM50 type grease).
. After 6-8 months of operation, disassemble the lateral box, dry the old oil on the inner wall of the box and the gaps between the flower shafts, and replace it with new oil.New travel cone: refuel after 20 days of initial use, and replace every 3-6 months thereafter (industry default uses Dow Corning's 2 # molybdenum disulfide grease).
.Electrical system maintenance
Motor inspection: Check for abnormal noise and vibration in the motor, and replace bearings if necessary.
.Hot box temperature control: Check the frequent temperature drop of the hot box, and check whether the control or display terminals have loose screws and poor contact.
.Fixed length control and cutting induction: Check for sensitivity issues with fixed length control and cutting induction.
.Wire ends and wire bars: Check for loose wire ends and loose wire bars, and tie and organize them.
.Heat dissipation of electrical cabinet: Conduct a thorough ventilation check for the cabinet's heat dissipation. Use compressed air to blow away dust from the cabinet's exhaust vents, internal ducts, and frequency converter fans to avoid thermal tripping.
. The protective net of the electric motor fan should also be blown clean to ensure smooth exhaust.
