With the increasing demand of the mechanisms of sand, the third generation Sand gravel production line productivity. Sand widely used, not only to improve the mechanism of sand production, and the quality is also more secure than the natural sand.
However, sand making machine during use, influenced by a variety of factors, restricting the performance of the play and service life of the Sand. One of the major problems currently facing is how to do sand making management and maintenance, fault prevention, the good condition of the machinery and equipment to maintain and give full play to the efficacy of equipment. Zhen Xin Machinery manufacturers as the third-generation Sand, sand making machine management to maintain, improve service life and put forward their own suggestions.
Currently, sand making production process management maintenance work, seriously restricting the sand making life and improving efficiency of the sand and gravel plant, which is mainly manifested in the following aspects:
First: Device Manager weak, affecting the normal order of production. Gap between the management and operation layer in the production process, resulting in a sand and gravel plant machinery and equipment management is weak. There are a considerable part of the sand and gravel plant does not form a complete and strict management system of mechanical equipment, machinery and equipment ledger, technical data file management system is not perfect, causing confusion in the management of machinery and equipment, and seriously affected the normal production of sand and gravel plant.
The second: Sand maintenance system may not be implemented to reduce the resulting mechanical equipment in good condition. Generally gravel plant equipment use are often re-use light maintenance Although the scheme given the man-machine system, but they ignore the constraints of mechanical equipment maintenance system activities, did not explicitly implement people. Operator just focus, not timely processing problems; mechanical equipment failure in need of repair, maintenance personnel responsible not cope with the job, failure is not a fundamental solution to the problem, "headache medicine head, feet sore foot ", resulting in the continuous expansion and development of the equipment failure. When a problem occurs, the operation and maintenance personnel tend to shirk their responsibility, not aware of the importance of the issue. This not only affects the quality and progress of the production also increased repair costs, running costs, and reduce the resulting sand making life and security.
Third: Sand is not standardized, accelerated equipment wear and tear of aging. Sand making technology, equipment use knowledge as part of the operating personnel is poorly understood, especially the technical quality of the short-term staff employed, do not pay attention to the specific conditions of construction and operating methods, just in time production, grab the progress, so sand making machine has been in a situation of overload, or with the "disease" job status, even illegal operation, thus accelerating the wear and tear of aging equipment. In addition, after the end of the project, the equipment can not be required to careful maintenance, repair and overhaul, to be deployed to the new project, the equipment often fails. Both spend a larger energy and the high cost of refurbishment, but also seriously bungled the normal construction period.
Fourth: ignore Sand upgrading, resulting in the construction of inefficiency and declining competitiveness. Present some gravel plants pay enough attention, and the upgrading of equipment failure and aging of the Sand slower. Part of the management to focus only on short-term economic benefits, just for the sake of convenience, without regard to the overall performance of the device, to adopt the practice of "robbing Peter to pay Paul", or even in violation of the relevant provisions of the State to continue to use worn-out machinery and scrap machinery, resulting in the mechanical failure rate greatly increase. Pose a security threat not only to the production staff, and the overall production inefficiencies, the overall increase in the cost of production, reduce the income of gravel plants, declining competitiveness, and ultimately affect the development of the entire factory.
To sum up, do a good job in sand making equipment maintenance and management work properly analyze and solve the various contradictions relationship management process, improve the management of sand and gravel plant equipment maintenance levels, improve sand making life, enhance the gravel plant market competitiveness has a very important practical significance.
