During the operation of the grooving machine, various common faults may occur. So, what are some common faults and their solutions? Below, the editors of GIRET Grooving and Edge - milling Machines summarize as follows:
The equipment fails to start or operates abnormally.
Possible Causes: Poor power supply connection. Motor overload, short - circuit or open - circuit in the winding. Damaged motor bearings. Excessive wear of carbon brushes, burned - out stator or rotor windings.
Solutions: Check the power supply circuit to ensure stable power supply and good contact. Inspect the motor and repair or replace the damaged components. Replace the worn - out carbon brushes and repair the stator or rotor windings.
Possible Causes: Low air pressure. Poor internal lubrication of the motor. Worn - out motor blades.
Solutions: Check the air source to ensure stable and sufficient air pressure. Regularly check and replenish the motor lubricant. If necessary, repair the internal blades of the motor and replace the worn - out parts.
The tool wears out quickly, becomes loose or breaks.
Possible Causes: High hardness of the material. Poor - quality tool. Improper tool installation or unclean installation surface. The tool is not suitable for the material of the pipe to be processed. Excessive feed speed or large cutting volume. Insufficient lubrication.
Solutions: Select a tool suitable for the pipe material. Check the tool installation method to ensure that the blade is sharp and installed correctly, and clean the installation surface. Adjust the feed speed and cutting volume to an appropriate range. Use lubricants such as saponified oil to reduce blade wear.
The transmission components are abnormal, and the equipment cannot operate normally.
Possible Causes: Loose or broken belt. Worn - out or damaged gears. Damaged bearings.
Solutions: Check the transmission components and replace the loose or broken belt. Replace the worn - out or damaged gears. Replace the damaged bearings.
The equipment vibrates excessively or generates abnormal heat.
Possible Causes: Unbalanced tool. Unstable equipment installation. Unsecured processed material. Poor lubrication or damaged rotating components.
Solutions: Balance the tool or replace it. Ensure that the equipment is installed stably and firmly. Add appropriate lubricating oil to ensure the normal operation of the lubrication system. Check and replace the damaged rotating components.
The groove surface is uneven or eccentric.
Possible Causes: Expansion - induced deformation of the pipe. Machine skew. Quality problems of the blade or improper installation method.
Solutions: Re - install the machine and expand and tighten the pipe to ensure the pipe is in the correct position. Adjust the level of the machine to ensure that the machine is stable and does not shake during processing. Check the quality and installation method of the blade to ensure that the blade is suitable for the pipe to be processed and is installed correctly.
The feed speed is inappropriate, resulting in poor groove surface quality.
The equipment cannot be operated normally, such as unable to adjust the speed, unable to start, etc.
Possible Causes: Damaged controller. Poor line contact. Sensor failure.
Solutions: Check and replace the damaged controller. Check the line connection to ensure good contact. Replace the damaged sensor.
In conclusion, the common faults of the grooving machine involve multiple aspects such as power supply, motor, pneumatic motor, tool, transmission components, equipment vibration and heating, groove surface quality, and feed system. When solving these faults, operations should be carried out strictly in accordance with the operation manual and safety regulations of the grooving machine, and professional maintenance personnel should be contacted in a timely manner for repair.
