What aspects does the routine maintenance of multifunctional spinning testing machine include?

The daily maintenance of multifunctional spinning testing machine mainly includes mechanical parts, electrical system, spinning system, hydraulic system, etc. The following are the specific contents:

Mechanical component maintenance

Regular cleaning: always clean the dust, oil stain and sundries on the machine body, transmission parts, workbench and other surfaces to prevent dust from entering the machine and affecting its operation. Clean it with a clean cloth or brush. For some corners and gaps that are difficult to clean, compressed air can be used for purging.

Check the connecting parts: regularly check whether the connecting parts of the testing machine, such as bolts, nuts and couplings, are loose, and tighten them in time if they are loose. For some parts that often vibrate, such as connecting bolts of motors and pumps, it is important to check them to prevent equipment failure caused by looseness.

Lubrication and maintenance: lubricate all moving parts regularly according to the requirements of the equipment manual. Such as lead screw, guide rail, bearing and other parts, should be coated or injected with proper amount of lubricating oil or grease regularly to reduce friction and prolong the service life of components. At the same time, pay attention to check the oil quality and oil level of lubricating oil, and replace the deteriorated or insufficient lubricating oil in time.

Check transmission parts: check the wear of transmission parts such as belts, chains and gears. If problems such as belt looseness, chain elongation or serious gear wear are found, they should be adjusted or replaced in time. For synchronous belt transmission equipment, pay attention to check the tension of synchronous belt to ensure the transmission accuracy.

Electrical system maintenance

Cleaning and inspection: regularly clean the dust in the electrical control cabinet to prevent dust accumulation from affecting the heat dissipation and performance of electrical components. Check whether the connection of electrical components is firm, whether there is looseness, oxidation, etc. If there is any problem, it should be handled in time. At the same time, check whether the wires and cables are damaged or aging, and replace them in time if damaged.

Temperature and humidity control: keep the temperature and humidity in the electrical control cabinet within a suitable range. Generally, the temperature should be controlled below 40℃ and the humidity below 80%. Temperature and humidity sensors can be installed in the control cabinet to monitor environmental parameters in real time, and air conditioning or dehumidification equipment can be installed if necessary.

Check the grounding system: regularly check whether the grounding system of the testing machine is good and whether the grounding resistance meets the requirements. Generally, the grounding resistance is not more than 4Ω to ensure the safe operation of the equipment and prevent electric shock accidents.

Spinning system maintenance

Cleaning of nozzle: after each use, the spinning nozzle should be cleaned in time to prevent the spinning raw materials from solidifying in the nozzle and blocking the nozzle. Special cleaning agent or solvent can be used to soak and rinse the nozzle, and then dry it with compressed air. Regularly check whether the nozzle hole of the nozzle is worn or deformed, and replace the nozzle in time if there is any problem.

Maintenance of metering pump: check whether the inlet and outlet pipelines of metering pump are blocked, and clean them in time if there is any blockage. Regularly calibrate the metering pump to ensure its metering accuracy. If the metering pump is found to have unstable flow or abnormal noise, it should be checked and maintained in time. It may be that the gears, shafts and other parts in the pump are worn and need to be replaced in time.

Raw material storage and transportation system: clean the raw material storage tank regularly to prevent raw materials from settling, caking or deterioration in the tank. Check the tightness of raw material conveying pipeline to prevent raw material leakage. At the same time, check the operation of the delivery pump to ensure that the raw materials can be delivered to the spinning nozzle smoothly.

Hydraulic system maintenance

Oil quality inspection and replacement: check the oil quality of hydraulic oil regularly, and replace the hydraulic oil in time if it turns black, turbid, smelly or abnormal in viscosity. Generally, the hydraulic oil should be replaced every 2000-3000 hours or every six months to one year, which can be determined according to the use of the equipment and the oil quality test results.

Filter cleaning and replacement: the filter in the hydraulic system should be cleaned or replaced regularly to ensure the cleanliness of hydraulic oil. Generally, the coarse filter should be cleaned every 200-300 hours, and the fine filter should be replaced every 1000-1500 hours.

Check the hydraulic components: check whether there are any problems such as leakage and abnormal sound in the hydraulic pump, hydraulic cylinder, hydraulic valve, etc. If there is any leakage, find the leakage point in time and repair it. Check whether the connection parts of hydraulic components are loose, and tighten them in time if they are loose.

Control system maintenance

Software maintenance: back up the parameters and data of the control system regularly to prevent data loss. If the software of the control system is found to be faulty or abnormal, the manufacturer should be contacted for maintenance or upgrade in time.

Sensor calibration: periodically calibrate various sensors on the testing machine, such as temperature sensor, pressure sensor and displacement sensor, to ensure their measurement accuracy and reliability. Generally, the calibration of sensors should be carried out once a year, which can be carried out by professional metering institutions.
