In the past month, with the help of factory leaders and workshop leaders, through the joint efforts of workers and colleagues, through their own positive efforts, we have done the following work.

1. Work attitude and ideological work.

I love my job, strictly self-discipline, abide by the rules and regulations of the factory, strictly control myself, straighten my post, and always maintain a "modest, cautious and self-disciplined" working attitude. With the care and training of the leaders and the help of my colleagues, I always study hard, make positive progress, strive to improve myself, always work hard, finish my tasks seriously and perform my duties. Adhere to ideals and firm beliefs. Constantly strengthen study, firmly establish the lofty ideal of socialism, firmly believe in taking the road of Socialism with Chinese characteristics, and consciously work hard to realize the basic line and program of the Party in the primary stage. Armed with Marxism–Leninism, Mao Zedong Thought, Deng Xiaoping Theory and Theory of Three Represents, we should thoroughly study and practice Scientific Outlook on Development and constantly strengthen professional study.

Two. 1. Equipment maintenance management.

(1) This month, the equipment management and maintenance work is based on the principle of "reducing costs and increasing efficiency" of the group company, and actively responds to the call of the branch factory and the equipment department to reduce costs. According to the basic drawings of thermal insulation water jacket provided by the equipment department, combined with the actual situation on site, draw CAD electronic drawings of thermal insulation water jacket and related parts drawings, and provide them to the equipment science and technology repair shop to save spare parts outsourcing funds. Use spare time to decompose and repair the damaged spare parts off the assembly line, so as to reduce the cost of spare parts as much as possible. This month, the cost of spare parts is 353,000 yuan, and the cost of a 750m3 impeller plate rack is153,000 yuan. The material cost is 99,305 yuan, saving 20,695 yuan. At the same time, the last week of this month is used to find out the surface and potential problems and deficiencies in team equipment maintenance management and daily inspection and maintenance, and put forward suggestions for solutions and rectification to prepare for full-load production.

(2) Although I have made continuous efforts in the management and maintenance of equipment in the workshop, equipment accidents continue to occur, which shows that my understanding of equipment in this workshop is not deep enough, and there are still big loopholes in equipment management, which urgently needs to correct the correct direction of equipment management and maintenance. At the same time, apply to the workshop for a selection team to study in the converter pump room for two weeks. After two weeks of study, I will work with the monitor to deal with equipment failures, install equipment and maintain it. Not only the model sizes of clean water, turbid water, oxygen lance pump and pipeline are recorded, but also the process parameters of each water supply pump are known. Replacing the 55KW motor with the purified water tower pump will draw the dimensions of the motor and the coupling at the pump end, which will provide data for future work. Understand the advantages of converter pump room team in equipment management and daily equipment maintenance. Find the relevant information of water pump maintenance on the internet and discuss the water pump maintenance project with the monitor. Confirm that the installation size of the water pump is generally 4-8mm, the water pump and the motor are misaligned, the radial displacement is less than 0.2mm, and the radial wear of the rolling bearing is less than 0.3 mm. Confirm the maintenance time of loading, framing 75C-L slurry pump and vertical pump. The frame filter press has broken down three times this month. On July 7th, it was found that the limit switch, hydraulic valve coil and relay were ablated by electric shock. The contacts of the relay work normally 1944 times a day. Because of the aging caused by electric shock for a long time, the faulty relay is replaced for troubleshooting. The other two times were hydraulic failures of the South boss crane. By solving the fault together with the master worker, the shortcomings of the converter pump house team in the maintenance of the hydraulic system of the plate-and-frame filter press were found. And go to Qingdao Library to borrow books about the basic knowledge of hydraulic pressure, study and study with the monitor and fitter monitor, and explain the principles of hydraulic pump and control valve of hydraulic system to the monitor. The method and experience of repairing the hydraulic control valve learned from the study and work in the continuous casting workshop were passed on to the team leader of the converter pump room, and the faulty control valve replaced by the plate-and-frame filter press was disassembled, cleaned and repaired. Through the installation of air compressor in brother workshop, we can understand the matters needing attention in the installation and use of air compressor.

(3) Replace the impeller

This month, it is planned to replace two impellers, namely 2 # and 4 # fans, for primary dust removal. In the middle of this month, the viscosity of 46# mechanical oil in 4# fan bearing thin oil station decreased, and impurities in the oil were slightly emulsified. No.4 airbag has abnormal sound fault. On the 27th, it is planned to replace the impeller of the 4# fan, clean the pipeline and replace the 46# mechanical oil drum of the dilute oil station. After replacing the impeller on 27th 17: 40, it was found that the temperature of the thrust pad in front of the impeller was abnormally high, which was 89℃. First of all, it is found that the cooling water channel is smooth and there is no fault. Secondly, due to the tight assembly of the thrust tile, it was judged that the temperature of the thrust tile was abnormal, and the fault of replacing the thrust tile before disassembling the fan impeller was not ruled out. Find the lubricating oil path of the bearing bush, and remove the oil inlet pipe of the front bearing bush and find that the throttle hole is blocked. Clean the orifice and troubleshoot the installation. Through this fault, I reflected on my ignorance of the structure of impeller bearing lubrication system. After changing the impeller oil, I didn't try to see if the oil circuit was smooth first. After the fault occurred, I judged that the fault direction was wrong, which led to a long time to deal with the fault. On August 3rd, it is planned to clean the 2# dust removal system and replace the impeller. When installing the impeller, draw lessons from the failure of the lubrication system of 4# fan, and test the lubrication system when installing the impeller. After starting, the new impeller vibrates normally and the lubrication system is normal.

(4) Find faults and improve equipment operation rate.

It is said that the equipment is divided into three parts and seven parts. Improper use and maintenance of equipment will reduce service life and increase failure rate. Maintenance frequency affects production. In the last week of this month, the time before the morning meeting of the workshop was used to focus on the use of vaporization and fan equipment. It is found that the operation of the water seal check valve on duty of the fan does not conform to the operating rules, and there is no sewage discharge at night. Too much mud in the water seal valve is easy to damage the water seal valve, and the resistance is great when recycling. 3# water seal valve oil-water separator has no oil level, 2# coupling has no oil level, and the oil level of vaporizing two-temperature hydraulic station is low. Mark the oil level of the hydraulic station, coupling and secondary dust removal bearing bush at the second temperature, and mark the lowest oil level on the equipment with paint. Supervise the equipment inspection and maintenance of each team.

(5) Work direction for next month.

Next month, I will focus on finding and rectifying my own problems in equipment management and maintenance, find out the problems of vaporizing fan system, and feed back the problems that have been found to the workshop and relevant leaders for more advice. Prepare to lay a nitrogen pipeline on the outer wall of the fan, connect the outlet of the positive pressure pipeline of the fan with nitrogen for back blowing, and add nitrogen into the water-sealed tank to drain the tank bottom, so as to improve the positive pressure drainage effect, prevent the positive pressure drainage from being blocked, and urge the vaporization to urgently need instrument spare parts.

In the future work, we should make up for the shortcomings and learn lessons. Try to do the work better.
