In practice, once the rolling bearing is assembled or disassembled, the end faces of the inner ring and the outer ring must have traces left during loading and unloading, and the color of the inner ring or outer ring surface will not be uniform, and there will be bright or dark. Aura; used rolling bearing, the rolling element and the raceway increase the clearance of the bearing due to wear, and the geometry and size of the rolling element will change when severe. First-timers may wish to find a pair of new bearings and a pair of "recycled" bearings (disposable bearings) carefully observed, compared, will have some experience.
The key to identifying and preventing "regeneration" bearings When assembling rolling bearings in equipment repair, the repair personnel should first identify whether the bearings used are "recycled" bearings. The methods for identification and prevention are as follows: (1) The inner and outer packaging of the bearings must be standardized. . Whether there is damage, whether there is a product certificate and the name of the manufacturer. (2) After unpacking, wash the anti-rust oil, wipe the bearing clean, and check whether the bearing type and grade are clearly legible. (3) Check the bearing's inner and outer ring ends for scratches, collisions, etc., and whether the contours of the inner and outer ring surfaces and the end face chamfer are uniform and there are no scratches. (4) Whether the processing marks and color of the inner ring and the outer ring surface are consistent, and whether there is a bright or dark halo. (5) Whether the processing lines on both end faces of the inner ring and the outer ring are uniform. (6) Whether there are signs of wear on the rolling elements and raceways.
Peristaltic Dosing Pumps Characteristic :
1 Clean and pollution-free: fluid only passes through and touches the Peristaltic Pump hose.
2. High precision: constant current, reproducibility of up to 0.5%, and flow can be precisely adjusted.3. Low shear force: It is an ideal tool for conveying shear-sensitive and corrosive fluids.
4. Corrosion resistance: it can transport various fluids, such as organic solvents and corrosive liquids.
5. Idling and dry operation: air or gas-liquid-solid three-phase mixed transportation can also be transported.
6. Possess self-priming ability: self-priming, no need to fill the pump, no need to empty.
7. It has the function of a shut-off valve, does not siphon, has no seals, and has the functions of a shut-off valve and a check valve.
8. Two-way conveying function: reverse pumping and back-suction functions can be realized by changing the direction of the pump runner.
9. Simple maintenance: only need to replace the peristaltic pump hose, no valve and seal replacement.
