The maintenance of electronic jacquard faucet machine should follow safety regulations, including pre operation preparation, component maintenance, electrical system maintenance, mechanical structure adjustment, and post maintenance testing. The following are specific maintenance steps and precautions:
1. Preparation before maintenance
Cut off power: Before maintenance, the power supply of the electronic jacquard faucet machine must be cut off, and a warning sign reading "Under maintenance, no closing" must be hung to prevent electric shock accidents caused by others' misoperation.
Prepare tools: Prepare corresponding tools according to maintenance needs, such as screwdrivers, wrenches, multimeters, etc., and ensure that the tools are intact and undamaged to avoid using damaged tools that may cause maintenance accidents.
.Understand the equipment: Familiarize yourself with the structure, working principle, and common fault phenomena of the electronic jacquard faucet machine, in order to quickly and accurately locate the fault point.
.2. Maintenance steps
Check the electrical system:
Check the power supply circuit: Check whether the power supply circuit is damaged, aged or has poor contact, and ensure that the power supply circuit is firmly connected and well insulated.
.Check the controller: Check whether the controller is working properly, such as whether the indicator light is on, whether the display screen is displaying normally, etc. If the controller malfunctions, it is necessary to troubleshoot and repair according to the fault code or phenomenon.
Check the solenoid valve: The solenoid valve is a key component of the electronic jacquard faucet machine, responsible for controlling the lifting and non lifting of the warp yarn.
. Check if the solenoid valve is damaged or blocked, and replace or clean it if necessary.Check the mechanical structure:
Check the hole selection needle: The hole selection needle is responsible for transmitting the pattern information on the pattern board to the jacquard machine.
. Check if the hole selection needle accurately falls into the hole of the patterned plate. If there is any deviation or damage to the hole selection needle, it needs to be adjusted or replaced.Check the vertical and horizontal needles: The vertical and horizontal needles are the executing components of the jacquard machine, responsible for converting the signal of the solenoid valve into the lifting action of the warp yarn.
. Check whether the vertical and horizontal needles are worn or broken, and replace them if necessary.Check the pressure grid: The pressure grid is responsible for adjusting the displacement distance of the vertical needle to ensure the accuracy of the jacquard pattern.
. Check if the pressure grid is in a tilted state. If the pressure grid is installed improperly, adjustments should be made to ensure that the vertical needle displacement distance is consistent.Cleaning and lubrication:
Cleaning equipment: Use a brush and vacuum cleaner to clean the dust and debris inside and outside the equipment, especially the contact surfaces of electrical components and mechanical parts, to ensure that the equipment is clean and free of dirt.
.Lubrication parts: Lubricate parts that require lubrication, such as bearings, gears, etc., to reduce wear and extend service life.
.III. Testing after Maintenance
Slow running test: After the maintenance is completed, perform a slow running test first to observe whether the equipment runs smoothly, whether there are any abnormal sounds or vibrations.
.Fast train operation test: After the slow train operation test is normal, conduct a fast train operation test to check whether the production speed and jacquard effect of the equipment meet the requirements.
.Check the textile fabric surface: Carefully observe the jacquard effect of the textile fabric surface to ensure that the pattern is clear and free of defects.
. If necessary, the equipment can be fine tuned to optimize the jacquard effect.IV. Precautions
Safety first: During the maintenance process, it is necessary to follow the safety operating procedures, such as wearing protective equipment, avoiding touching live parts, etc., to ensure personal safety.
. Record the maintenance process: Detailed records of the maintenance process, replaced parts, and adjusted parameters for future reference and traceability.Regular maintenance: Establish a regular maintenance system to regularly inspect and maintain the electronic jacquard faucet machine, promptly detect and handle potential faults, and ensure long-term stable operation of the equipment.
