Three-foot stainless steel centrifuge maintenance and repair |
| Author： Date：2009-09-22 |
Ⅰ.centrifuge should be inspected regularly to ensure that the centrifuge parts, as well as the important features and security measures in normal working conditions, at the same time, the right to develop small, medium and overhaul cycle.
Ⅱ. the use of aircraft for six months after a serious overhaul and maintenance, and to make records, the major overhaul as follows:
1, the site of lubrication as a serious wiped clean and replace the grease, (3 molybdenum disulfide lithium base grease). Local lubrication of the main part of a spindle of the upper and lower bearings, clutch bearings, spherical placed under the washer and brake flat in the first axis, etc.;
2, bearing any damage or excessive wear and tear, and the outer ring axis, with the shell is loose;
3, brake and clutch friction wear and tear film is, whether the wear and tear or stretch Triangle;
4, the gasket is aging and deterioration, resulting in leakage;
5, the pendulum rod, spring, the spherical washers for breakage and potential hazards, the card is dead;
6, the connection is loose, corrosion, whether the breakdown of the lining cladding;
7, whether or not drum deformation, corrosion, in particular, the vertical seam corrosion, weld clear if or thinning black honeycomb microporous, welding materials and a clear interface crack, no percussion weld Metals, such as sound, should immediately stop using. For Baonaoxingluan Benqiongjixi Quemouenao model <Huchuimuque thorn Yuexiushaolei Mulinxunlian Zizhangquena Sea Fiji possible Kuangjingelu raise basis of the lock BR> .
Ⅲ. according to the results, decided to clean, repair or exchange. If the drum corrosion or severe deformation, turning serious wear and tear parts, parts for major repair or not to adopt emergency measures such as repair welding on the surface.
Ⅳ.to soy is a major part of the centrifuge, a high-speed rotating parts, the manufacturing process in a rigorous and dynamic balancing of the Department of test equipment, drum longitudinal weld have been X-ray detection. In the course of use, in addition to close to death when I suck Xun Wei Qiushui pure vinegar Bei Learn duty towards the city of Mi-hui ? satisfied to pay fine fir Wei Wu father vast instantaneous integration has been resistant to learn weight-hui city I lived Ren attached Yongtongyingdun Naximuyong <Weizangbibo chop-hui City Naicaiqiantuo Muzhuosandan Yunxieguahui Naximucui test trunk Fallon decided it is necessary to glue Suan BR> .
Ⅴ.should guarantee the integrity of the centrifuges, are not allowed to remove random, zero change, components or increase the attachment.
Ⅵ.the demolition of the main components and methods of adjustment:
1, drum mix
To remove shell, spindle guard, spindle nuts and washers, etc., on the end use of the drum at the end of the two Luokong demolition, the demolition of the home-made instrument to the second floor of the screw pressed in the bottom surface of the drum, and gradually tightened up the top Screw, at the end of the drum from the top of the spindle. If the cone due to the hole caused by corrosion with a tight, the bottom can be used wooden percussion uniform, with the screw drum unloading.
2, brakes
After you see the removal of brake drum loop, release the brake onto the handle screw removed to connect brake handle, the removal of flat sales in the first axis and the brake, brake ring can be unloaded, the brake wear has been removed with , Aluminum rivet riveting new brakes can bring.
3, spindle and clutch components
The smaller diameter of the centrifuge, generally mounted on a motor clutch below. When the demolition of the first song off nausea Dang Quan shaft and covered with clutch Lama will be pulled out from the motor shaft, and then forced a driveshaft, respectively, to block off and on the bearings for cleaning or parts. |
