(1) Significance and content of equipment operation management
Equipment is the material and technical basis of modern production. Whether the production of sewage treatment plant can be carried out smoothly depends mainly on the perfection of machinery and equipment.
Sewage treatment plants have a large number of treatment facilities (or structures) and auxiliary production facilities. Production process equipment, such as grid trash rack, pump, mixer, fan, dosing equipment, sludge concentration dehydrator, mixing and stirring equipment, air diffusion device, electric valve, etc. The failure of these process equipment will affect the operation of the sewage plant or lead to the shutdown of the whole plant.
The operation management of sewage treatment plant equipment refers to the management of the whole production process from equipment selection, installation, operation, maintenance to scrapping. Therefore, the content of equipment operation management can be summarized as the following main aspects.
① Reasonable selection and safe use of equipment. For example, choose advanced technology, energy-saving and consumption-reducing equipment, arrange its appropriate production tasks and loads according to the performance of the equipment, and create good working environment conditions for the equipment; Arrange equipment operators with certain technical level and proficiency. (2) Do a good job in equipment maintenance and repair.
(3) According to the needs and possibilities, the equipment shall be updated and reformed in a planned way. ④ Do a good job in equipment acceptance, registration, storage and scrapping. ⑤ Establish equipment management files. 6. Do a good job in handling equipment accidents.
(2) Operation and management of equipment
(1) Although the manager is responsible for compiling the management system of mechanical equipment operation and maintenance, and compiling the annual maintenance plan and spare parts procurement plan; Responsible for the management of procurement, account establishment, allocation and scrapping; Compile and draw equipment atlas or documents; Responsible for providing technical solutions for renovation, participating in overhaul, renovation and renewal of equipment, presiding over testing and acceptance, and participating in equipment safety inspection and accident analysis and handling.
(2) The operator responsibility system includes the post responsibility system, operating procedures, inspection system, and succession system for operating equipment personnel.
(3) Mechanical equipment operation procedures such as equipment dispatching procedures, emergency handling procedures and accident handling procedures.
(3) Equipment maintenance management
(1) The contents of equipment maintenance management: Establish mechanical equipment files, such as name, performance, drawings, documents, operation date, test data, maintenance records, etc. Adhere to the mechanical equipment maintenance and repair system. Formulate maintenance procedures for mechanical equipment, such as technical standards, procedures and acceptance of maintenance. Establish spare parts and spare parts system. ② Equipment wear and maintenance
First, the concept of equipment wear and tear will produce two kinds of wear and tear in the long-term use of equipment. One is material wear, which refers to the loss of friction and vibration caused by mechanical force during use; Second, technical wear and tear, such as equipment scrapped due to improper operation or other reasons, can no longer be used; Or because of the progress of science and technology, the same-purpose equipment with better performance and efficiency continues to appear.
In this way, the "value" of the original old equipment is reduced. Formally, the former is called visible wear and the latter is called invisible wear and tear.
B. Work category of equipment maintenance The contents of equipment maintenance include lubrication, corrosion protection, cleaning and replacement of parts. Generally speaking, equipment maintenance is divided into the following categories.
(a) Daily maintenance This is the external maintenance of the equipment, such as cleaning, inspection and oiling, which should be carried out by the operators as one of the contents of the shift change.
(II) Level I Maintenance Inspection and maintenance of the vulnerable parts of the equipment, including cleaning, lubrication, partial and key disassembly and adjustment of the equipment, are generally carried out by operators under the guidance of full-time maintenance personnel.
(c) The second-level maintenance strictly inspects and repairs the equipment, including replacing parts and repairing the accuracy of the equipment. Be undertaken by full-time maintenance technicians.
(d) Minor repairs This is a local repair with the least workload, and only local repairs, replacements and adjustments are carried out. (e) Medium repair This is a planned maintenance with a heavy workload. The sewage treatment plant will be arranged for three years 1- 1 time, including the replacement and maintenance of the main parts of the equipment, the overall inspection and adjustment of the equipment, so that the equipment can meet the due technical standards.
(f) Overhaul This is a planned repair with the largest workload, including comprehensive disassembly, inspection, repair, replacement and adjustment of the equipment, and finally reassembly into a new complete machine, and repainting or painting the appearance of the equipment. Usually only once every few years or even ten years, it can be completed by a professional (repair) factory. C. Planned maintenance of equipment During the use of equipment, spare parts and key components will continue to "wear", thus affecting the performance, efficiency and safety of equipment. Equipment top repair system is a working system that checks and repairs the equipment in a planned way according to the "wear" law of the equipment through daily maintenance to ensure that the equipment is always in good condition.
The main contents of the equipment pre-repair system include daily maintenance, regular inspection and planned maintenance.
(3) the principle of equipment maintenance work
Pay equal attention to maintenance and planned maintenance, and give priority to prevention. Adhere to good maintenance, can reduce.
