The inspection cycle of the conveyor belt vulcanizing machine should be determined in combination with the usage intensity and working conditions. The following are the recommended inspection cycles under different situations:
First, the regular inspection cycle
Daily inspection: Before each use, check the stability of the mobile equipment, the lubrication and firmness of the transmission components, the operating status of the electrical equipment, the accuracy of the vulcanization thermometer, and pre-fill the nozzles to prevent leakage or blockage.
Monthly inspection: It is recommended to conduct a comprehensive inspection once a month, covering the degree of wear of transmission components, the amount of lubricating oil, the working condition of the vulcanization thermometer or control system, and temperature stability, etc.
Second, the inspection cycle for special working conditions
High-frequency usage scenarios: If the equipment operates for more than 8 hours a day or handles high-load tasks, the inspection cycle should be shortened to once every 15 days, with a focus on monitoring the pressure stability of the hydraulic system, the uniformity of the heating plate temperature, and the heating of electrical components.
In harsh environmental scenarios: When the dust concentration exceeds the standard or the humidity is greater than 85%, the aging condition of the sealing parts and the clogging degree of the filter screen should be checked weekly, and the hydraulic oil filter element should be replaced monthly.
Third, the special inspection cycle for key components
Hydraulic system: Inspect the oil tank filter every quarter, replace the hydraulic oil and clean the micro-filter every six months, and conduct a pressure test for the sealing performance of the hydraulic system every two years.
Heating system: Use an infrared thermometer to test the temperature uniformity of the heating plate every month, check the resistance value of the heating sheet every six months, and verify the accuracy of the temperature controller every year.
Electrical system: Check the insulation of the circuits weekly, test the grounding resistance quarterly, and conduct the withstand voltage test of electrical components annually.
Fourth, inspection cycle during the period of suspension
Short-term shutdown: If the machine is shut down for more than 7 days, it is necessary to power on and heat it to 100℃ every week and maintain it for 30 minutes to prevent the water pressure plate from getting damp.
Long-term shutdown: If the machine is out of service for more than one month, a complete functional test should be conducted monthly, including pressure holding test of the hydraulic system, detection of the heating rate of the heating plate, and insulation test of the electrical system.
