Persistence of noise appearance and methods in imported bearings

This noise is declared by adhering to the free oscillation of the frame during the rotation of the imported bearing and its impact with the roll or ferrule. It can be present in all types of bearings; but its sound pressure level is not too high and is low frequency. Its characteristics are:
a. Stamping holders and plastic holders can be attacked.
b. Whether it is thin oil or grease is smooth.
c. When the outer ring accepts bending moments, it is most likely to occur.
d. When the radial clearance is large, it is simple to present.
Because it is inevitable that the voids in the frame and the gap between the frame and the ferrule will exist in the bearing product; it is not easy to completely eliminate the sound of the frame; but it can be improved by cutting the installation error; .
Another kind of sticking special sound is because the conflict between the supporting frame and the guiding surface of other bearing parts causes the self-excited oscillation of the holding frame to sizzle. The punching of the deep groove ball bearing is more than that of the 蚝 蚝 蚝婺诘 婺诘 淝斩冉 停 停 停 逦榷ㄐ 逦榷ㄐ 逦榷ㄐ 逦榷ㄐ 逦榷ㄐ 逦榷ㄐ 逦榷ㄐ 逦榷ㄐ 逦榷ㄐ 逦榷ㄐ 逦榷ㄐ 逦榷ㄐ 逦榷ㄐ 逦榷ㄐ 逦榷ㄐ 逦榷ㄐ 逦榷ㄐ 逦榷ㄐ 逦榷ㄐ
When the imported bearing is under the radial load effect and the grease function is poor; the noise of “咔嚓, 咔嚓” will be heard at the beginning of the work; this is mainly because the roll body is out of the load zone; the roll body is suddenly accelerated and the frame is maintained. The noise announced by the collision; this kind of impact is inevitable but will not be seen after a period of work.
The way to avoid sticking noise is as follows:
a. In order to ensure the stability of the auger movement; the ferrule guiding method should be selected as much as possible and the guiding surface should be given ample smoothness; the tapered roller bearing layout under high-speed working conditions should be improved; the roller-guided L-shaped holding frame should be changed to a set. Z-shaped frame supported by the rim.
b. When the bearing rotates at a high speed; the bearing with large pockets has a oscillation amplitude that is much larger than the oscillation amplitude of the bracket with a small gap; therefore, the value of the pocket gap is particularly important.
c. Pay attention to minimize radial clearance.
d. Try to improve the accuracy of the production of the price; improve the surface quality of the frame; help reduce the noise of the rollover and the collision.
e. Actively use leading cleaning skills; useful complete removal of spare parts and finished products; improve the cleanliness of bearings.

Liposuction Pump

The Peristaltic Pump can be used in liposuction surgery, in the process of swelling anesthesia, used to deliver saline.
The definition of swollen anesthesia is to infiltrate into subcutaneous adipose tissue by ultra-low concentration, high-dose, a large-volume local anesthetic (currently used lidocaine) as an anesthetic method for liposuction.
Swelling anesthesia was first proposed by Klein in 1987. It is also called [over-perfusion anesthesia". A large amount of solution containing adrenal and lidocaine is stably perfused into the skin through a peristaltic pump, causing edema and cell tissue gap in the subcutaneous tissue and its structure. The small blood vessels are separated and pressed to be locked, thereby achieving the effects of local anesthesia, pain relief, hemostasis, and tissue separation.

Swollen anesthesia can be used as separate local anesthesia or combined with general anesthesia or regional anesthesia.

The advantage of peristaltic pump in swelling anesthesia:
1, easy operated, non-contamination
2, foot pedal control ,safety & reliability
3, adjustable speed and left/right direction optional

4, Power-down memory function
