6, sewage treatment system which generally have instrumentation?
Instrumentation equipment: a variety of balances, laboratory commonly used analytical instruments, electromagnetic flowmeter, level gauge, air flow meter and dissolved oxygen analyzer.
7, sewage treatment system equipment management points which are the main?
Sewage treatment system, the equipment management has the following four points:
(1) use good equipment
All kinds of equipment must have operating procedures, the provisions of the operating steps. The equipment operating procedures are based primarily on the combination of the site conditions of the manufacturer's instructions. Workers must operate in strict accordance with the operating procedures. Equipment used in the process to record.
(2) to maintain good equipment
All kinds of equipment should be developed maintenance regulations, maintenance regulations in accordance with the equipment manufacturer's instructions on the combination of the scene to develop, but also the maintenance regulations on the operating procedures together. Maintenance regulations include cleaning, adjustment, fastening, lubrication and corrosion and other content. Maintenance work should also be recorded. Maintenance work can be divided into: routine maintenance - refers to the operation of the inspection inspection and maintenance. Inspection and maintenance - regular downtime inspection and maintenance. Parking maintenance - refers to the maintenance of spare units or idle equipment. Seasonal maintenance - refers to the equipment into the summer, winter, rain and other seasonal needs of the maintenance work, including sunscreen, cold, moisture, cooling and other measures.
(3) maintenance of good equipment
The development of equipment for major equipment maintenance standards, through maintenance, recovery of technical performance. Some equipment, to clear the big, medium and small repair boundaries, division of labor to implement. The main equipment must be clear maintenance cycle, the implementation of regular maintenance, do not damage to the very serious when you think of repair. For routine repair, should be developed to repair the workpiece quota, in order to reduce maintenance costs, each maintenance should be a detailed record.
(4) manage the equipment
The term "tube" refers to the management of the entire process from the purchase of equipment - installation - commissioning - acceptance - use - maintenance - maintenance - scrap - update the whole process. Including capital management of equipment (overhaul costs, depreciation fees, etc.) for each link should be provided for the provisions.
8, sewage treatment system equipment, what is the perfect standard?
The following criteria can be used as a good standard:
(1) equipment performance is good, the main technical performance to the original design or minimum should meet the sewage treatment process requirements.
(2) operation control of the safety system is complete, action sensitive and reliable.
(3) stable operation, no abnormal vibration and noise.
(4) electrical equipment insulation and safety protection device should be consistent with electrical installation procedures.
(5) equipment ventilation, cooling and cooling, sound insulation complete system, the effect is good, the temperature rise in the rated range.
(6) inside and outside the equipment clean and tidy, good lubrication, no leakage (oil, leak, air leakage, leakage).
(7) operating records, technical information is complete.
9, sewage treatment system equipment maintenance cycle generally how much?
Equipment used after a period of time, must be minor repair, repair, or overhaul Some equipment manufacturers clearly defined its minor repair, overhaul period; some equipment is not clearly defined, it must be based on the complexity of the equipment, vulnerable parts Durability and maintenance conditions to determine the repair cycle. Repair cycle refers to the equipment between the two repairs between the working hours, sewage treatment system, a number of equipment overhaul cycle as table. (For reference only) Preface Device name Overhaul (hours) Regular maintenance
1 centrifugal sewage pump<600r / min 40000 500 2 centrifugal sewage pump <800r / min 30000 500
