With the extensive application of the continuous development of science and technology, new technologies, new processes, the type of concrete mixer is more complete, more complex structure, superior performance, higher concrete mixer technical skills and equipment maintenance requirements. Mechanical equipment operator should have certain skills: judgment and repair the fault, and should have a high sense of responsibility and professionalism.
The premise and foundation equipment is routine maintenance and upkeep. In the long concrete mixers, different environments use, wear and tear of mechanical components, the gap increases, with changes directly affect the balance of the original equipment. Stability of the equipment, reliability, efficiency will be reduced to a considerable extent, and even lead to the loss of its inherent mechanical equipment essential performance, can not run normally. So, the device must be overhauled or replaced with new equipment, which will increase the cost of doing business, the impact of the rational allocation of corporate resources. It must establish a scientific and effective device management mechanism, increase the intensity of the daily management of the device, combining theory with practice, scientific and reasonable maintenance equipment maintenance program.
(1) maintenance principles and requirements: concrete mixer maintenance priorities are: cleaning, lubrication, inspection, fastening and corrosion. Care must implement the principle of "both maintenance and repair, prevention-oriented" and do regular maintenance, force, correctly handle the relationship between the use, maintenance and repair, not only allowed to keep, just repair support. Maintenance of machinery to ensure the quality, according to the provisions and requirements of the project one by one, shall not leak protection or security. Maintenance projects, maintenance of quality and maintenance problems found should make records at the department is working.
(2) implementation and monitoring of maintenance operations: Mechanical Maintenance adhere to promote a "clean, lubricate, adjust, tighten, corrosion" as the main content of the "cross" working method, perform routine maintenance and periodic maintenance of the system, in strict accordance with the instructions provided to use periodic maintenance and inspection projects. Routine maintenance is cleaned and inspected before and after the operation of machinery and processes carried out, mainly to check vital, vulnerable parts of the case, coolant, lubricants, fuel quantity, instrumentation instructions.
