Stainless Steel Diaphragm For Pump,High Strength Wear Resistance
Product Overview
Several sets of diaphragms (stainless steel sheets) are alternately
bolted to the two coupling halves, and each set of diaphragms is
formed by stacking several pieces, and the diaphragm is divided
into a link type and a whole shape of different shapes. The
diaphragm coupling relies on the elastic deformation of the
diaphragm to compensate the relative displacement of the two
shafts. It is a high-performance flexible coupling for metal strong
components. It does not need oil, has a compact structure, high
strength and long service life. It has no rotating gap, is not
affected by temperature and oil pollution, and has the
characteristics of acid resistance, alkali resistance and corrosion
resistance. It is suitable for shafting transmission in high
temperature, high speed and corrosive medium working conditions.
Feature
Each set of couplings is composed of a plurality of diaphragms with
a thickness of 0.2-0.6 pieces, and the outer edges of the sheets
are elastic with a circular arc shape, and the shape is simple, the
processing is convenient, the construction period is reduced, and
the number of sides is small. Elasticity is better than the number
of sides and the stability is good.
Compared with the toothed coupling, the coupling diaphragm has no
relative sliding, no lubrication, no sealing, no noise, no
maintenance, and is easy to manufacture. It can partially replace
the gear coupling. Diaphragm couplings are common in industrial
applications in the industrial world.
Application
-DT(LT) Series FGD Engineering Pump
-TL(R) Series Desulfurization Pump
Use and maintenance:
First of all, before installation, the end faces of the two axles
should be cleaned and the end bonding cooperation checked.
Secondly, after installing the diaphragm coupling, if normal
operation, all the screws must be checked. If loosening is found,
it must be tightened, so several classes can be repeated to ensure
that it does not loosen.
Thirdly, in order to prevent fretting wear and high-speed operation
of diaphragm, leading to micro-cracks in bolt holes, the diaphragm
can be coated with solid lubricants, such as molybdenum disulfide
or antiwear coating on the surface of the diaphragm.
Fourth, overloading and accidents should be avoided.
Fifth, in the process of working, it is necessary to check the
abnormal phenomena of diaphragm coupling, such as abnormal
phenomena and maintenance.
Sixth, appropriate safety measures must be taken in every place
where personal and equipment accidents may occur due to diaphragm
coupling.
