To understand the structure and performance of the carton production tester, to correctly grasp the use of the instrument's method of use and a brief maintenance, repair techniques, you can extend the life of the test equipment, improve the detection accuracy, but also conducive to quality inspection personnel to carry out quality monitoring work. And can greatly improve the inspection efficiency and the quality of raw materials and carton products monitoring. The following exchanges are made on the simple maintenance and repair of carton production inspection instruments.
Brief maintenance and repair techniques To master the use of food methods, procedures, and testing range, so as not to affect the measurement
The moisture level, rust resistance, dust resistance, shock resistance, and calibration level of the mechanical parts of the instrument must be well established and the specified type of grease should be injected. For the electrical parts of the original device, power supply, sensors, converters, monitors, etc. to do a good job of insulation, rat-proof, temperature control, reduce oxidation, aging, leakage, short circuit, circuit breakers cause electrical damage.
All kinds of glassware and optical instruments should be handled lightly and gently, and they should be protected from sudden cooling, sudden heat, medium shock, collision, dust and mildew. In particular, the mirror surface and the polishing surface of the optical components cannot be directly picked up by hand, and it is necessary to wear a fine yarn glove or a pad to take it on a soft silk cloth. When wiping, it can only be lightly rubbed with a fine silk cloth.
All kinds of measuring instruments on the knife, scales, indicators to prevent damage, to keep clean, and regular measurement departments.
The mechanical system is subject to wear, rust, dust, oil, fracture, damage, falling into foreign matter, looseness or improper operation resulting in "deadness" in the active parts, slippage, vibration, unsynchronized operation, screw screw adjustment, sound temperature Abnormalities can be checked by seeing, listening, measuring and touching.
The malfunction of the electrical appliance will appear, the indicator light will not be on, the display will not show or the data display is abnormal, and the switches, fuses, filaments, and electrical devices may be checked for leakage or bad contact. The resistance, voltage, current, and injection may be measured accordingly. The signal, replace the original device in question to investigate.
æ›° The pointer distortion, scale mark wear, paint peeling, blurring, display electrical signal interruption, or electrical parameter anomaly on the reading position should be changed in order to affect normal display and accurate reading.
Analyze and judge the condition of the instrument. If there is a fault, disassemble the instrument and carefully observe the mutual assembly relationship of various components before starting work. Accuracy of assembly and disassembly procedures are best recorded for disassembly of complex components to prevent errors during recovery. Do not forcibly disassemble components that are difficult to disassemble. Use rubber-plastic or wooden hammers. Gently knock them and loosen them to remove them. Parts of different materials, such as metal, rubber, glass, and magnetic materials, should be stored separately. At the same time, they should be protected against loss. In particular, magnetization can affect the use of components. Components that do not have to be removed must not be easily removed. The failure to solve the problem is best solved by professional machinery.
Overhauled assembly
Repair and replacement of parts that have been damaged, incomplete, deformed, deteriorated, rusted, worn, broken, loosened, or leaked, etc., must be reset as is. Pay attention to the fact that the front and back surfaces cannot be turned upside down. Accuracy must be within the tolerance range. If it is required to be in the horizontal position (zero position), it cannot be omitted. The lubricant should be used with care that the type of oil used and the order of oil injection should not be reversed.
After the instrument is repaired and installed, it is required to carry out a no-load and actual-load trial operation. The direct impact on measurement readings shall also be marked: éš¹ Measurement department verification to ensure that the instrument's detected data and instrument performance parameters are in accordance with Requirements, to verify the operation and use of the situation, and make a record of the record.
