Zhu Changcheng Diqing Petrochemical Company, Heilongjiang Daqing 163714 life and operational reliability play a vital role. Based on their actual work experience, the basket is simple to analyze how to properly maintain and maintain the screw air pressure hole. 1 Intake air filter maintenance and maintenance The air filter is a component that filters out dust such as dust in the air. The filtered clean air enters the compression chamber of the screw rotor for compression. Due to the internal clearance of the screw compressor, only the space of the particle size within 15 ports is allowed. If the air filter is clogged or broken. A large amount of particles larger than 151 enter the screw machine, which not only greatly shortens the service life of the lubricating oil filter fine separator, but also causes a large amount of particulate matter to directly enter the bearing cavity, accelerates the bearing wear, increases the rotor clearance, reduces the compression efficiency, and even the rotor due to the gap. Unreasonable and impact friction, shorten the rotor removal, air filter core is best to maintain once a week, unscrew the gland nut, take out the filter element, use 020.4Mpa compressed air, sweep from the filter cavity to the outside, with a clean The rag wipes the dirt on the inside of the filter housing. When refilling the air filter, it is important to note that the seal ring on the front of the air filter should be in tight contact with the inner end of the case. 1500 hours of replacement, in particularly harsh environments or different seasons, such as the northern winter and spring and autumn wind season, it is recommended to replace the secondary air filter every 500 hours. After cleaning or replacing the air filter, the parts must be reassembled in the original assembly form and sequence to prevent foreign objects from falling into the intake valve. In normal times, it is necessary to check the intake telescopic tube for damage and flattening deformation, and whether the connection between the expansion joint and the air filter intake valve is loose or leaking. If abnormalities are found, they must be repaired and replaced in time. 2 Lubricating oil filter replacement The new lubricating oil filter should be replaced after 500 hours of the first operation. Use a special wrench to rotate the oil filter to remove the new filter. Before installing it, it is best to add the screw oil filter seal. Use both hands to screw back the oil filter seat and tighten it tightly. It is recommended to replace the new filter element every 15002000 hours. It is best to replace the oil filter element when changing the oil. When the environment is bad, the replacement cycle should be shortened. It is strictly forbidden to use the sleeve filter overdue. Otherwise, because the filter plug is severely blocked, the pressure difference exceeds the load capacity of the bypass valve, the bypass valve automatically opens, and a large amount of particles will directly enter the screw main unit, resulting in random oil. Serious consequences. 3 Maintenance of oil fine separator The oil separator is a component that separates the screw oil from the compressed air. Under normal operation, the service life of the oil separator is about 3000 hours, but the quality of the oil and the filtration accuracy of the air. It has a great influence on its life, and it is necessary to shorten the maintenance period of the air filter in a harsh environment, and even consider installing a front air filter. The oil fine separator must be replaced after the expiration or before and after the pressure difference exceeds a12Mpa, otherwise the motor overload oil separator will be damaged and run. 4 screw oil maintenance and replacement of screw oil has a decisive impact on the performance of the oil injection screw machine, good oil has good oxidation stability, separation, rapid foaming, high viscosity, good corrosion resistance, therefore, the user must Use pure special screw oil. After the new machine is running for 500 hours, it is necessary to change the oil for the first time, and then replace the new oil every 2000 hours. It is best to change the oil filter at the same time when changing oil. Reduce the replacement cycle when using in harsh environments. Replace the method, start the air compressor to run for 5 minutes, so that the oil temperature rises above 500, the viscosity of the oil drops. 2 Stop running. When there is 0. port 3 pressure in the fuel tank, open the oil drain valve at the bottom of the fuel tank and connect the oil draining barrel. The oil drain valve should be slowly opened to prevent the oil from being sprayed with the pressure of the pressure belt. When the lubricating oil is dripping, close the drain valve. Open the oil filter and drain the oil in each line at the same time. Put on a new oil filter. 3 Open the fuel filler port and plug in new oil, so that the oil level is within the range of the oil mark. Tighten the fuel filler port to check for leaks. 4 Lubricating oil must be inspected frequently during use. When the oil level line is too low, it should be replenished with new oil in time. The lubricating oil must also be used to discharge condensed water frequently. The general situation is to discharge once a week, and should be discharged in 23 days in high temperature climate. Times. Stop for more than 4 hours, open the oil drain valve without pressure in the fuel tank, drain the condensate, and quickly close the valve when the organic oil flows out. 3 Lubricating oil is strictly forbidden to be mixed with different brands. It is strictly forbidden to use the lubricating oil over time. Otherwise, the lubricating oil quality will decrease, the lubricating performance will decrease, the burning point will be lowered, and the high temperature shutdown will be easily caused, causing the oil to spontaneously ignite. 5 Cooler maintenance The cooling effect of the cooler directly affects the operating temperature of the air compressor. The plate-fin structure is also prone to dust accumulation. Therefore, the maintenance of the cooler needs to use a dry compressed air of 0.493 or more per shift to blow down. After blowing, the dust particles in the air hood are cleaned to prevent the dirt from being blown into the cooler again by the fan, causing blockage and causing high temperature of the machine. If the machine is used in a harsh environment and the cooler is full of oil, it must be cleaned with a carbon cleaning agent. Etc., the law enforcement files of the procuratorate were established as the basis for performance appraisal. 23 Construction of the Procuratorate Conference Paperless System Improves the Standardization of the Operation Mechanism of the Procuratorial Committee The Procuratorial Committee is the operational decision-making body of the procuratorate and plays an important role in researching and solving major and complicated cases. It is also the procuratorial organ's establishment of a case management mechanism that cannot be ignored. Aspect. To improve the quality of work and efficiency of the Procuratorate, it is first necessary to standardize the proceedings. Through the construction and application of the conference proceedings system, it ensures that the procuratorial committee makes decisions democratically and scientifically. 24 The sound statistics of the procuratorial business of sound cases use computer network technology to standardize case management, and should also realize the connection between the case handling system information and the procuratorial business statistical reporting system, in order to truly target the objective of the business decision. In order to ensure the integrity of the information, the People's Procuratorate of Guandu District of Kunming City is responsible for accepting the case. From the date of acceptance, the case information is entered into the case management system. All the data about the case are based on the case information of the daily entry. Automatically generate and import the unified statistical card system to ensure the authenticity of the procuratorial business data, thus objectively and comprehensively reflecting the true situation of the procuratorial business. At the same time, in order to strengthen the analysis and research of business data, master the business work dynamics and social security conditions, and provide objective and accurate data for leadership decision-making.
