Time：

2026-01-26

The daily maintenance of a rubber hose extruder encompasses the following aspects: routine upkeep, periodic servicing, maintenance after prolonged shutdowns, troubleshooting abnormal noises, keeping the production environment clean, servicing the gearbox, preventing foreign objects from entering, maintaining the cooling water lines, prohibiting no‑load operation, assigning dedicated personnel for maintenance, inspecting DC motors, and calibrating temperature control instruments.

Daily Maintenance and Care Procedures for Rubber Hose Extruders

The daily maintenance and upkeep of a rubber hose extruder encompass the following aspects:

Daily maintenance : Includes cleaning the machine, lubricating all moving parts, tightening any loose threaded fasteners, and inspecting and adjusting the motor, control instruments, working components, and piping. Routine maintenance is typically performed during equipment operating hours and does not consume operational time.

Regular maintenance : Typically, this is performed after the extruder has been in continuous operation for 2,500–5,000 hours. It involves disassembly and inspection, measurement, and assessment of wear on major components; replacement of parts that have reached their specified wear limits; and repair of damaged components.

Long-term storage and maintenance When the equipment is to remain out of service for an extended period, anti‑rust lubricant should be applied to all working surfaces, including the screw, barrel, and die head. Small screws should be suspended or stored in wooden crates and supported with wooden blocks to prevent deformation or damage.

Abnormal Noise Processing If abnormal noises occur during extruder operation, stop the machine immediately for inspection or repair.

Clean production environment : Maintain a clean production environment to prevent debris and contaminants from entering the material, which could clog the filter plates, reduce product yield and quality, and increase die head resistance.

Gearbox maintenance As with standard gear reducers, inspect gears, bearings, and other components for wear and failure. Use the specified lubricant and add oil to the prescribed level. Any leaking seals in the gearbox should be replaced promptly.

Prevent debris from entering : Strictly prevent metal or other foreign objects from entering the hopper; install magnetic separators or magnetic racks at the feed inlet to keep debris out, and pre‑screen materials before feeding.

Coolant Hose Maintenance : Inspect the inner walls of the cooling water pipes for scale buildup and the exterior for corrosion and rust, and implement descaling and anti-corrosion measures.

No idling with an empty vehicle. : Do not run the machine empty to prevent the screw and barrel from becoming worn or damaged.

Dedicated personnel are responsible for maintenance and upkeep. : Designate a dedicated person to oversee equipment maintenance and servicing, and meticulously document each maintenance and repair activity in the factory’s equipment management records.

DC Motor Inspection : Inspect the brushes for wear and contact condition, measure the motor’s insulation resistance, check the connecting wires and other components for rust, and implement appropriate protective measures.

Temperature Control Instrument Calibration : Regularly calibrate temperature control instruments and verify the accuracy of their adjustments and the reliability of their control functions.
