Laboratory Peristaltic Pumps operates by pumping fluids through the Peristaltic Pump tube squeezed rotating rollers in the pump head that squeeze the liquid out of the tube with compression force.
The peristaltic pump is a liquid delivery device that can control the flow rate. It has the characteristics of high delivery accuracy, strong corrosion-resistance, small shearing effect, simple operation, easy maintenance, and can effectively avoid cross-contamination. It has a very wide range of laboratories. Applications. From cell culture to in vitro organ research, from material preparation to water treatment technology optimization, from food ingredient extraction to food preparation technology improvement, Peristaltic Dosing Pumps may be used as power to achieve accurate fluid transmission and processing operations during the experiment.

TIMKEN joint bearing can be used for discriminating; mainly considering the degree of damage of TIMKEN joint bearing, mechanical properties, importance, working conditions, and the time to the next inspection. If there are the following shortcomings, it can no longer be used; it is necessary to replace it. TIMKEN joint bearing. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
1. There are cracks or gaps in any of the inner ring, the outer ring, the roll body and the cage.
2. There is crack on any one of the ferrule and the rolling body.
3. There are significant card injuries on the rolling track, ribs and roll.
4, the cage wear is significant or the rivet is significantly relaxed.
5. There is rust on the raceway surface and the rolling body; there is injury.
6, there are severe indentations and marks on the raceway surface and the rolling body.
7. There is significant creep in the inner diameter surface of the inner ring or the outer diameter surface of the outer ring.
8, the color change due to heat is significant.
TIMKEN joint bearing sealed with smooth grease; damage to the seal or dust cover is significant.
Most of the TIMKEN joint bearing damages are caused by many loads beyond the original estimate; non-useful seals, too tight TIMKEN joint bearing clearances caused by too tight cooperation, etc. Any of these elements have their own special Damaged type and will leave special damage marks. Therefore; inspection of the bearing of the damaged shaft; in most cases, the cause of its ability can be found; in general; one third of the TIMKEN joint bearing damage is caused by fatigue damage The other third is due to poor smoothness; the other third is due to contamination of the TIMKEN joint bearing or device disposal.
However, these types of damage are also related to industrial types. For example, the pulp and paper industry is mostly caused by poor smoothness or contamination to form TIMKEN joint bearing damage rather than data fatigue.
