| Shenzhen lianxin testing equipment co., LTD is a professional manufacturer of wire tester, shenzhen lianxin testing analytical instrument maintenance program, the importance of instrument maintenance, and teach you how to correctly maintain the instrument. This paper provides you with a comprehensive understanding of the structure and performance of the production detector, the correct grasp of the use of the instrument and the simple maintenance, maintenance skills, can extend the service life of the instrument, improve the detection accuracy, but also conducive to the quality inspection personnel easy to carry out quality monitoring work. The following is about the production of testing equipment for simple maintenance and maintenance matters needing attention. To master the use of the instrument operating procedures, measuring range, so as not to affect the accuracy of the measurement. To do a good job of moisture-proof, rust-proof, dustproof, shock-proof, calibration level of the mechanical parts of the instrument, and inject the specified type of lubricating grease. To electrical parts of the original components, power supply, sensors, converters, displays, etc., to do a good job in insulation, anti-rodent, temperature control, reduce oxidation, aging, leakage of electricity, short circuit, circuit damage caused by electrical parts. The knife edge, scale and indicator on all kinds of measuring instruments should be protected from damage and kept clean. For the mechanical system due to wear, rust, dust, oil, fracture, damage, falling into foreign bodies, loose or improper operation caused by the relevant parts of the "crash", slipping, vibration, operation is not synchronized, screw screw can not move, abnormal sound temperature, can be seen, heard, measured, touch for investigation. To the electrical fault appears start not to move, the indicator light is not on, the display is not shown or the data shows abnormal, can check whether the switch, fuse, filament, electrical parts leakage, or bad contact, and can be measured by the resistance, voltage, current, injection of the corresponding signal, replace the original device to troubleshoot. To the reading part of the pointer deformation, scale scale wear, paint off, fuzzy, monitor electrical signal interruption or electrical parameters abnormal, affect the normal display and accurate reading should be replaced. By analyzing and judging the condition of the instrument, if there is a fault, it can be disassembled, and before starting to carefully observe the mutual assembly relationship of various parts. Assembly accuracy and disassembly procedures. It is best to record the disassembly of complex parts to prevent errors during recovery. Do not disassemble the parts that are not easy to disassemble forcibly, should choose rubber plastic, wooden hammer, knock gently to make it a bit loose after disassembly. Parts and parts of different material such as metal, rubber, glass, magnetic body, should be stored separately, at the same time to prevent loss, especially after being magnetized will affect the use, is not necessary to disassemble the parts and parts never easily disassemble, the failure that does not grasp to solve to oneself had better ask professional machinery to repair. Through the replacement and repair of damaged, incomplete, deformation, rust, wear, fracture, loose, leakage and other fault parts, assembly recovery, to reset according to the original program, pay attention to the front and back and up and down direction can not be reversed, the assembly precision to ensure that within the tolerance range. Requirements in the horizontal state (zero) can not be omitted, the use of lubricating oil to pay attention to the type of lubricating oil and the sequence of oil not reversed. After the repair, installation and debugging of the instrument, it shall be carried out no-load and in-load trial operation. For those directly affecting the measurement reading, it shall be checked by the metrological department to ensure that the data detected by the instrument and the performance parameters of the instrument meet the requirements. The operation and use shall be identified and recorded and archived. As for the maintenance of wire tester (wire tester), we have conducted long-term practice and summarized as follows: Keep the instrument itself clean and dry. Shenzhen lianxin testing equipment co., LTD. Is a manufacturer of wire testing machine, environmental simulation test equipment and mobile phone test equipment. All staff of shenzhen lianxin testing equipment co., LTD. Welcome your presence. |
