Teach you the proper use of various workbenches
When you buy a workbench, quality inspection is an indispensable part. Only by grasping the accurate method, we don't have to worry about buying a poor quality workbench. In the process of testing, we have certain indicators. What kind of indicators are normal, no impact on quality, and more than what indicators, quality will have an impact, these are all we need to understand and grasp. In this way, a high-quality workbench can be purchased to ensure the performance and longevity of the product. Of course, in addition to mastering the correct method of purchase, the correct operation method for all types of workbench needs to be understood. Today, Xiaobian uses the lean tube workbench and the ultra-clean workbench as examples to teach you how to use it correctly:
1. How to use the ultra-clean workbench?
The ultra-clean workbench is a purification device designed to meet the strict requirements of modern industrial technology for the cleanliness of the work area, providing a local clean working area of up to 100 levels for the user's needs . Due to its high cleanliness and mobility, it is widely used in laboratories, biomedicine, microelectronics, precision instruments and other fields. Next, we will introduce the Shenzhen Clean Workbench, the details are as follows.
The ultra-clean workbench laminar flow air unit module can be connected and used , making the ultra-clean workbench widely used in clean room , ultra-clean workbench, clean production line, assembled clean room and laminar flow hood. The purification workbench is equipped with an initial and high efficiency two-stage filter. The fan draws air from the top of the FFU and passes through the primary and high-efficiency filters. The filtered clean air is sent out at a constant speed of 0.45 m/s ± 20 on the entire air outlet surface . Utilizing the new US technology, it is suitable for obtaining a high level of clean environment in various environments. It provides high quality clean air for clean rooms and micro-environments of different sizes and cleanliness levels. In the new clean room and clean factory renovation, the cleanliness level can be improved, the noise and vibration can be reduced, and the cost can be greatly reduced. The clean bench in Shenzhen is easy to install and maintain, and is an ideal component for a clean environment.
Super clean workbench management
(1) at each use clean benches, laboratory personnel should open the clean table of the UV lamp, UV radiation for 20 minutes using.
(2) Turn on the working power of the ultra-clean workbench , turn off the UV lamp , and spray the disinfection work surface with 75% alcohol or 0.5% peracetic acid .
(3) During the whole experiment , the experimenter should operate according to the aseptic procedure .
(4) After the end of the experiment , wipe the work surface with disinfectant , turn off the working power , and turn on the UV lamp again for 15 minutes .
(5) In case of failure of the unit , the animal laboratory should be notified immediately , and the professional should continue to use it after passing the inspection .
(6) The experimenter should pay attention to keep the room clean and tidy .
(7) The filter material of the ultra-clean workbench is replaced once every 2 years , and the replacement record is made .
Second, how to use anti-static workbench?
Static electricity is ubiquitous in our lives, sometimes affecting our normal work, so the application of anti-static workbench is more and more extensive, anti-static workbench should be strictly in accordance with operational requirements, then you do not understand those requirements?
1. The grounding state must be good. The resistance values ​​of the static static safety worktable pads, anti-static mats, anti-static wrist straps, and grounding cables must be measured frequently to maintain normal values.
2. The insulating parts of work clothes, work chairs and tools should be sprayed with antistatic agent.
3. Clean the anti-static mat and floor mat to choose to wash with neutral detergent and water.
4. The building floor should also be treated once a week, using antistatic solution
5. The resistance value of the ground wire configuration system should also be regularly maintained.
3. How to use the lean tube workbench?
(1) From the setting of the fault, the assessor shall not promptly go ahead.
(2) According to the fault phenomenon, the possible causes of the fault on the electrical control line, determine the scope of the fault.
(3) During the troubleshooting process, Au stays 0 major failure. In the specified time, lj continues to smear failure
(4) f purchase and use the Republican instrument.
Indexing the indexing, indexing and positioning of the flexible tube table. It is automatically carried out according to the instructions of the control system, and each time the index is rotated by a certain angle, but the transmission mechanism that realizes the indexing of the table is difficult to meet the requirements of the indexing accuracy, so special positioning components are required to ensure. Commonly used positioning components include pin positioning, reverse positioning, toothed disc positioning and steel ball positioning.
In China's toothed disc ( also known as rat sprocket ) positioning indexing table application zui is common. Widely used in CNC machine tools, also used in combination machine tools and other special machine tools. It can achieve high indexing accuracy, generally 23 seconds, and Zui can be up to lo . 4 seconds. Can withstand a large load, high positioning stiffness, and good precision retention. The structure of the THK6370 automatic tool change CNC horizontal boring and milling machine indexing table. It mainly consists of a pair of indexing spurs 13 and 14 , a sling cylinder 12 , a piston 8 , a hydraulic motor, a worm gear pair 3 , 4 and a reduction gear pair 5 , 6 . The indexing and indexing action includes: 1 picking up the worktable, disengaging the toothed disc, and completing the preparation before the indexing; 2 rotating indexing; 8 working table descending, the toothed disc re-engaging, and the positioning clamping is completed.
