RFID technology in equipment inspection application of technical indicators
Equipment inspection work is to protect the smooth operation of equipment is an important measure, inspection is a time-intensive work, requiring duty personnel must be periodic inspection of each inspection point. However, the manual inspection, it is difficult to effectively monitor the inspection staff on duty, resulting in frequent inspection reports are not in place, failure to deal with incidents caused by various incidents; In addition, the paper inspection can not pass the real-time inspection data, these metropolitan Resulting in failure to deal with not timely, affecting all types of equipment to run safely and effectively.
Use of RFID technology and wireless LAN for equipment and pipeline inspection, usually used in power, manufacturing equipment inspection, petrochemical pipeline inspection. In the factory area, a seamless wireless network is covered along the inspection route. A RIFD label is installed at each inspection site. The label records the basic information of the inspection site. Each inspection personnel to a patrol point first read the contents of the tag with a handheld, check the equipment and pipelines, the test information transmitted to the management office through the wireless network. Backstage establish a inspection management system, through the system to achieve inspection quality inspection staff, inspection equipment to improve the management level, improve inspection efficiency, inspection of the entire inspection work situation.
Oil refinery equipment and pipeline inspection refers to the equipment security department on its plant equipment, pipes for regular inspections, inspection, in order to ensure the safety of oil transportation and refining. For a long time the inspection work of the refinery has been using the "one form" of work. Inspection personnel inspection equipment and pipelines in accordance with the inspection route, and then select the operating conditions on the form, return to the management of statistical inspection. Due to lack of conscientious inspection personnel, weather conditions and other factors, sometimes patrols lazy, misrepresenting the inspection, making the quality of security inspection greatly reduced.
Equipment inspection system based on RFID technology includes inspection delivery management, inspection line management, inspection information download management, inspection information upload management, inspection information query management, inspection information report management. Hardware devices mainly by RFID handheld terminals and RFID tags, wireless access points. In this system design, closely around the industry's core needs and inspection operations of key business processes, and the close combination of RFID technology in the practical needs of the application, such as the choice of electronic tags using the ultra-high frequency passive electronic Label, the corresponding reading distance should be larger, so as to accurately detect the electronic label information.
Inspection business operations process:
RFID tags are placed at the existing inspection points, the labels are initialized and the basic information of the inspection points is recorded, such as the inspection number and the inspection site;
The establishment of inspection management information system, through the system for the management of all business operations in the system of inspection operations, management, statistics, analysis;
When there are plans for inspection will be entered into the system, such as inspection personnel, inspection routes, departure time, requirements, etc., and then sent to the inspection tasks RFID handheld reader, and then leave the inspection staff;
Inspection personnel in accordance with the inspection mission began inspection, the detection point RFID reader near the inspection inspection point, it can automatically record the testing staff detection;
Inspection of the situation and the results can be real-time upload via wireless LAN network to the management information system can also be returned to the management center will be patrolled data uploaded to the management information system;
The management center can check the completion of the inspection plan through the management information system, and can query and print the corresponding inspection statistics.
The inspection equipment system fully utilizes the physical advantages of RFID technology and mainly makes use of the features of the UHF RFID without contact and reading distance without manual intervention so as to improve the inspection convenience of inspection personnel and greatly reduce the inspection time Check the staff workload. Reading distance can achieve long-distance data acquisition, better remote inspection equipment; RFID recognition speed, reducing the number of inspection time, improve efficiency and improve the management of equipment inspection; RFID technology can be appropriate Through the cloth, leather, wood that material to read, and can fully meet the harsh environment challenges, keep the work around the clock.
What matters is that RFID technology brings real-time and accurate data, giving managers access to insight into the data and turning that insight into best practices for business management, improving management and predictive capabilities, and promoting overall Efficiency and management improvement.
The outer Spherical Ball Bearing is what we usually call the outer Spherical Bearing. The reason why it is called ball bearing is that it belongs to Deep Groove Ball Bearing, and the rolling element in it is steel ball.
Deep groove ball bearing outer spherical ball bearing is convenient to use the main characteristics of simple for loading and unloading, self-aligning ball bearings, standard tolerances for internal and external diameter reduction, adding tolerances to ensure the shaft with the light; each set of ball bearings are not alone to use and he must match to bearing inside the whole machine, the outer spherical bearing are of various shapes so the overall fit for various structural position after use. The ball bearing of the outer sphere can be divided into three categories according to the way of matching with the axis.
Outer spherical ball bearing with top wire
Its code is: UC200 series (light series), UC300 series (heavy duty Series), and deformation products UB (SB) 200 series. If the environmental load is small, UC200 series should be selected generally, otherwise UC300 series should be selected. Generally, there are two top threads on the outer spherical ball bearing, the angle between them is 120 degrees. The characteristic is that when the shaft fits with the shaft, the top wire is applied to the shaft to play a fixed role, but the environmental requirements for its matching must have a small vibration range. This kind of spherical ball bearing is widely used in textile machinery, ceramic machinery and other manufacturing industries.
Spherical spherical ball bearing with taper
Its name is: UK200 series, UK300 series. The inner diameter of the outer spherical ball bearing is the taper hole with a ratio of 1:12. When used, it must be combined with the tight sleeve. The characteristics of this kind of outer spherical bearing are: it can bear more load than the outer ball bearing with top wire. Because the diameter matched with the locking set the same model than with the top wire outer spherical ball bearing small, such as with the top wire outer spherical ball bearing UC209 inner diameter is 45mm, and is matched with the diameter of the shaft is 45mm, and if if change into a tapered outer spherical ball bearing, can only choose 45mm diameter sleeve, and 45mm adapter sleeve with taper outer spherical ball bearing is UK210 (of course, if the load is higher then you can choose the UK310). As a result, the load on UK210 is much larger than that of UC209.
Spherical spherical ball bearing with eccentric sleeve
Its name is: UEL200 series, UEL300 series, SA200 series. The main characteristic of this kind of spherical ball bearing is that there is a certain eccentricity on the upper end of the bearing, and the eccentric sleeve with the same eccentricity is cooperated with it. These bearings can also be said to be a special bearing, because it is mainly in agricultural machinery (harvester, straw machine, threshing machine etc.) on the use of this kind of outer spherical ball bearing is mainly used to beat hard structure, combined with the eccentric structure can effectively reduce the dynamic jump violently.
Double layer seal
The outer spherical ball bearings than other ordinary bearings is a double seal, because the outer spherical ball bearing the use of environmental conditions are harsh, especially agricultural bearing even more, and the double sealing to ensure the dust is not easy to enter the channel within the last two years, some companies developed the outer spherical bearing three lip seal the more greatly enhance dustproof ability, prolonging the service life of the bearing.
