Common failures and solutions of the guide rails and slider in hydraulic pipe benders

Guideway common faults and solutions

Guideway wear leads to increased clearance, slider and guideway guide clearance is too large, making abnormal noises

Reason: guide rail use time is long, be worn out

Solution: check the degree of wear and tear of the guide plate, depending on the degree of wear to determine whether to replace the guide plate, and re-adjusted to meet the requirements of the clearance

Corrosion or corrosion points on the surface of the guide rail, processing accuracy decreased

Causes: corrosive dust and fumes generated during processing are deposited on the surface of the guideway.

Solution: every half a month to clean the guide rail bender, clean before closing the bender, remove the dust on the surface of the guide rail and smoke deposits

Guideway daily maintenance recommendations

Regular cleaning: clean the guideway once every half month to prevent dust and smoke deposits from affecting machining accuracy and guideway service life.

Check fasteners: Regularly check the fasteners such as screws at the rail connection to prevent loosening and affecting the smoothness of mechanical movement.

Slider common faults and solutions

Slider action is not smooth or crawling

Causes: the hydraulic system into the air, the oil level is too low; the cylinder is pulled inside the hair; solenoid valve poor contact

Solution: add hydraulic oil; repair the cylinder; overhaul the solenoid valve wiring

Slider movement speed is slow

Causes: insufficient pressure in the hydraulic system; insufficient lubrication of the slider

Solution: adjust the pressure of the hydraulic system; add the appropriate lubricant to the slider

Slider and guide rail clearance is too large

Causes: slider or guide rail wear

Solution: check and repair or replacement of worn parts

Slider action is not accurate

Causes: hydraulic system failure; slider position sensor failure

Solution: check the hydraulic system, repair or replace the faulty parts; check and repair or replace the position sensor

Abnormal noise generated by the slider

Causes: poor contact between the slider and the guide rail; loose internal parts of the slider

Solution: Check and tighten the internal parts of the slider; adjust the contact state between the slider and the guide rail.

Slider Maintenance Recommendations

Regular lubrication: Add suitable lubricant to the slider regularly to reduce friction and improve the smoothness of movement.

Check the gap: Regularly check the gap between the slider and the guide rail to ensure that it is within the normal range, to avoid too large or too small a gap to affect the performance of the equipment.

Clean the slider: clean the surface of the slider regularly to prevent dust and debris from entering the inside of the slider and affecting its normal movement.

Check the hydraulic system: check the hydraulic system regularly to ensure that the level of hydraulic oil is normal, the oil quality is good and free of impurities and moisture.

Fastening components: Regularly check the screws and other fasteners on the slider to prevent loosening and affecting the smoothness of mechanical movement.
