two.

1. Equipment maintenance management work.

This month's equipment management and maintenance work is based on the principle of “reducing costs and increasing efficiency” of the group company. It actively responds to the cost reduction call of the branch and equipment department. According to the basic drawing of the insulated water jacket provided by the equipment department, it is combined with the actual situation measurement. The hot water cover cad electronic drawings and related parts drawings are provided to the equipment major repair factory to save spare parts and purchase funds. Use the spare time to repair and disassemble the damaged spare parts, and try to reduce the spare parts cost. The spare parts cost this month is 353,000 yuan, the plate and frame yuan, and the 750m3 impeller is 153,000 yuan. The material cost is 99,305 yuan, saving 20,695 yuan. At the same time, the last week of the month is used to find the surface and potential problems and deficiencies in the equipment maintenance management and daily inspection and maintenance of the equipment, and propose solutions to the rectification and preparation for full-load production. .

Although I have been working hard on the maintenance and repair of equipment in the workshop, the equipment accidents continue to occur, indicating that I am not deeply aware of the equipment in this workshop. There are still many loopholes in equipment management, and it is urgent to correct the correct direction of equipment management and maintenance. At the same time, apply to the workshop to select the converter room to re-learn for two weeks. After two weeks of study, work with the class to deal with equipment failures, install equipment, and maintain equipment. Not only the model size of the water, turbid water, lance pump and passage are recorded, but also the process parameters of each water supply pump. Use the clean water tower pump to replace the 55kw motor opportunity mapping motor and pump end coupling size archive for future work. Learn about the strengths of the converter pump house team in equipment management and daily equipment maintenance. Go online to find the relevant information of pump maintenance and discuss with the class to discuss the pump maintenance project, confirm that the gap between the two ends of the pump installation is generally 4-8mm, the different axial degrees of the pump and the motor, the radial displacement should not exceed 0.2mm, scrolling The radial wear of the bearing should not exceed 0.3mm. Confirm the loading, frame 75c-l slurry pump, vertical pump refueling maintenance time. This month, the frame and frame filter presses have a total of three faults. On July 7th, the north automatic plate frame has no frame return action to find the limit switch. The hydraulic valve coil and the relay are judged to be relay electric shock ablation and oxidation. The relay contacts are normal every day. 1944 times of work, the reason is that the electric shock is used for a long time, and the fault relay is replaced. The other two were hydraulic failures of the South Boss frame machine. Through the failure of working with the workers' masters, the inadequacies in the maintenance of the hydraulic system of the plate and frame filter press were found. And went to the Qingdao Library to borrow back the relevant hydraulic basic books, study and study together with the team leader, and explain the hydraulic system hydraulic pump and control valve principle to the team leader. The experience of the method of repairing the hydraulic control valve learned during the study and work in the continuous casting workshop will be explained to the head of the converter pump room, and the fault control valve replaced by the frame filter press will be dismantled for cleaning and maintenance. By installing an air compressor in the brother workshop, you need to pay attention to the installation and use of the air compressor.

Replace the impeller

This month, the plan to replace the two impellers is a dust removal 2#, 4# fan. In the middle of this month, the ## fan shaft and thin oil station appeared 46# mechanical oil viscosity decreased, oily mild emulsification and impurities. 4# The air bag sound is abnormally faulty. On the 27th, the 4# fan plan was replaced with the impeller cleaning path, and the thin oil station 46# mechanical oil and steam drum exchange work. At 17:40 on the 27th, after replacing the impeller, the temperature of the impeller front thrust tile was abnormally up to 89 °C. The reason for the parking search was first to find the cooling waterway and found that the cooling waterway was smooth and did not malfunction. Secondly, it is judged that the tension of the thrust pad is too tight, which causes the temperature of the thrust tile to be abnormal. The failure of the replacement of the fan impeller in front of the fan impeller is not ruled out. Look for the bushing lube road. Disassemble the front shroud inlet pipe and find that the throttle hole is blocked. Clear the orifice, the installation troubleshooting. Through this fault, it is reflected that the structure of the impeller bushing lubrication system is not known. After replacing the impeller, the oil path is not tested first. After the fault occurs, the fault direction is judged to be wrong, resulting in long processing failure time. On August 3, the plan was to clean the 2# dust removal system and change the impeller at the same time. When installing the impeller, draw lessons from the failure of the 4# fan lubrication system and test the lubrication system when installing the impeller. After the start-up, the new impeller vibration normal lubrication system is normal.

Look for problems and improve equipment operation rate.

As the saying goes, the device is divided into 3 points and 7 points. If the equipment is not properly maintained, the service life will decrease and the failure rate will increase. Maintenance frequency affects production. In the last week of the month, use the workshop before the morning meeting to focus on the use of vaporization and fan equipment. It was found that the operation of the wind turbine check valve was not in accordance with the operating regulations, and the water seal check valve did not discharge during the night shift. The water seal valve is likely to cause damage to the water seal valve in the mud, and the resistance is large when recovering. 3# Water-sealing valve oil-water separator has no oil level, 2# coupling has no oil level, and the vaporization of the two-way throat hydraulic station is low. The Erwen throat hydraulic station, coupling, secondary dust-removing bearing oil level are specified, and the minimum oil level line is delineated on the equipment by paint. Supervise the equipment inspection and maintenance of each team.

Work direction next month.

Next month, we will focus on rectifying our own problems in equipment management and maintenance, find out the problem of vaporization fan system, and feedback the problems we have found to the workshop and relevant leaders, and ask the workshop and relevant leaders. Prepare to lay the nitrogen channel of the fan external wall, connect the blower outlet of the positive pressure passage of the fan to the nitrogen backflushing and the method of adding the nitrogen to the bottom of the tank to increase the positive pressure drainage effect, prevent the positive pressure drainage from being poor, and prompt the vaporization shortage. Instrument spare parts.
In the future work, we must make up for the shortcomings and learn the lesson. Work hard to do a better job.
