(1) The significance and content of equipment operation and management
Equipment is the material and technical basis of modern production. Sewage treatment plant production can be carried out smoothly, mainly depends on the degree of perfection of machinery and equipment.
The sewage treatment plant has a large number of treatment facilities (or structures) and auxiliary production facilities. Production process equipment such as grating interceptor, pumps, agitators, fans, dosing equipment, sludge thickener dewatering machine, mixing and stirring equipment, air diffusion devices, electric valves and so on. The failure of these process equipment will affect the operation of the sewage plant or cause a plant-wide shutdown.
The operation management of sewage treatment plant equipment, refers to the whole process of production equipment management, that is, from the selection, installation, operation, maintenance until the end of the whole process of management. Therefore, the content of equipment operation and management can be summarized in the following major aspects.
①Reasonable selection, safe use of equipment. For example, the selection of advanced technology, energy-saving equipment, according to the performance of the equipment,
Arrangement of its appropriate production tasks and loads for the equipment to create a good working environment conditions; arrangements for a certain level of technical skills and proficiency of the equipment operator.
② good maintenance and overhaul of equipment.
3 according to the needs and possibilities, planned equipment upgrading and reconstruction.
④ good equipment acceptance, registration, storage, scrapping work.
⑤Establish equipment management files.
6 Do a good job of handling equipment accidents.
(2) the operation and management of equipment
①managers, although the responsibility
compile the enterprise's machinery and equipment operation and maintenance management system, the preparation of the annual maintenance plan and spare parts, spare parts purchase plan; is responsible for purchasing, accounting, allocation until the end of the management; compiling and drawing the equipment atlas or archives; is responsible for the provision of renewal, transformation of the technical program, to participate in the equipment of the overhaul and transformation, Renewal work, and preside over the testing and acceptance, participate in equipment safety inspection and accident analysis and treatment.
② operator responsibility system
Including the operation of equipment staff job responsibility system, operating procedures, inspection system, shift handover system.
③ mechanical equipment operating procedures
such as equipment scheduling procedures, emergency procedures, accident procedures.
(3) Maintenance management of equipment
①Contents of equipment maintenance management
Establishment of machinery and equipment files, such as name, performance, drawings, documents, operation date, test data, maintenance records. Adhere to the mechanical equipment maintenance and repair system. Establishment of overhaul procedures for mechanical equipment, such as technical standards for overhaul, procedures for overhaul, acceptance of overhaul, and so on. Establishment of spare parts, spare parts system.
② equipment wear and maintenance
a, the concept of equipment wear
Equipment in the long-term use of the process will produce two kinds of wear. One is material wear and tear, refers to the use of mechanical forces caused by friction, vibration loss; the second is the technical wear and tear, such as improper operation or other reasons resulting in equipment scrapped, can no longer be used; or due to scientific and technological advances, better performance and efficiency of the same purpose of the equipment continues to appear,
this results in the original old equipment, "value" is reduced.
The original old equipment "value" reduced. From the form, the former is called tangible wear and tear, the latter is called intangible wear and tear.
b, equipment maintenance work category
Equipment maintenance content, including lubrication, corrosion, cleaning, parts and components control replacement, generally equipment maintenance is categorized as follows.
(a) routine maintenance
This is the cleaning, inspection, refueling and other external maintenance of equipment, undertaken by the operator, and as one of the contents of the handover.
(b)First-level maintenance
The inspection and maintenance of the equipment's wearable parts, including cleaning, lubrication, dismantling and adjusting of the equipment's localization and key points, are generally undertaken by operators under the guidance of full-time maintenance personnel.
(c) the second level of maintenance
strict inspection and repair of equipment, including the replacement of parts and components, repair the accuracy of the equipment. Undertaken by full-time maintenance skilled workers.
(d) minor repair
This is the smallest workload of localized repairs, only local repair, replacement and adjustment.
(e) medium repair
This is a larger workload of planned repairs, sewage treatment plant arrangements for 1-3 years 1 time, the content of the replacement and repair of the main parts of the equipment, inspection of the entire equipment and adjustments to the corrections, so that the equipment can meet the technical standards that should be.
(f) overhaul
This is the largest workload of a planned repair, including a comprehensive dismantling of the equipment, inspection, repair, replacement, adjustment, and finally reassembled into a new machine, and the appearance of the equipment for repainting or painting. It is usually carried out only once every few years or even ten years, and can be done by a professional (repair) shop.
c, the plan of equipment repair system
Equipment in the process of use, parts, key components will continue to "wear and tear", which will affect the performance of equipment, efficiency and safety. Equipment top repair system is based on the equipment "wear and tear" law, through the daily maintenance of planned inspections and repairs to ensure that the equipment is often in a good condition of the work system.
The main content of the equipment repair system includes routine maintenance, regular inspection and planned maintenance.
③ equipment maintenance work principle
maintenance and planned maintenance and prevention. Adhere to good maintenance,
can be mitigated.
