October 19, Anqing Petrochemical Electric Department to keep up with the pace of the Ninth Conference, the organization of the elite will be on the sewage treatment of carbon equipment for small technical transformation, tackling the investment is no longer 'dystocia', so that the safe operation of environmental protection devices.
Sewage treatment The cast-in-place unit has been continuously operated since its inception, and the activated carbon powder has been put into the PACT biochemical tank. When the powdered activated carbon is mixed with the reflowed carbonaceous sludge, the activated sludge adheres to the surface of the powdered activated carbon and greatly increases The use of carbon equipment at the same time with the cost of saving investment, flexible operation and convenient, high utilization of activated carbon and many other advantages.
18, as the maintenance task of the electrical department of the oil refining electrical work area to maintain two classes of workers in the inspection, found that the device motor body temperature is higher, the inverter reported to ground failure. Monitor class Yin Yue informed the situation immediately after the people The motor to disassemble the inspection, shake insulation, cleaning motor stator, to prevent the conductive performance of the toner into the motor stator coil, resulting in ground fault, check finished, restore the installation immediately after the use of 19:00 at 8:00, the motor again Issued a 'brain stem' alarm, Yin Yue immediately rushed to the scene, for maintenance and power failure tickets, he immediately came to the investment device, in a dark space to remove the motor and gear box connection screws, In the lubricating oil, so as not to penetrate the ground lubricants, resulting in maintenance personnel slipping or polluting the environment, and then the motor from the high-profile, with the rope along the charcoal pipe, slowly the motor hanging to the ground, disintegrated, found the motor rotor Due to aging and 'end of life'.
In order not to affect the normal operation of environmental protection equipment, so that the sewage treatment rate of 100%, Yin Yue co-manager in charge of Ding Hansong actively looking for a backup machine. Through careful search and found a set of machine for the German production, but if the use of complete sets of equipment, Gear box, and equipment installation location is small, only one person sideways construction, high 'barrel' light within the dark, to the demolition work to bring some difficulty, and time-consuming and labor. Ding Han Song after a comprehensive analysis, decided to new Motor and the new gear box detachment, and change the new motor running mode, the motor triangle into a star connection, and the old gear box connection. Yin Yue immediately led the staff to install a good size, re-create contact points, the rapid motor To the scene in place to install them with a rag to wipe the black carbon around the carbon machine, clean the old gearbox, and then connect the motor with the gear box, with a fire mud blocking a cable jacket to prevent toner into the impact of motor use life.
17:30 points, after more than 10 hours of continuous rotation, and finally successfully completed the maintenance tasks, so that the investment device to resume operation, to ensure the safe operation of sewage treatment.
