? Jun. 7, 2008 - Bearing the real comparison
|
True bearing consistent with the use of the
name, type and technical specifications; does not allow a 1-micron or 0.1
microns in error; bearing materials using high-quality, high cost of bearing
steel materials to ensure Cylindrical Roller Bearing Tapered Roller Bearing the quality, transport Process would take special
care. Bearing the appearance of fake and genuine, but its bearing capacity,
speed limits, and so I wonder if it is consistent with the purposes; to reduce
manufacturing costs, the accuracy without any requirement for lower prices, the
use of poor quality bearing steel materials, packaging, The treatment of
non-standard, bearing products have a negative impact on the accuracy, the
bearings will be in use early damage.

? May. 28, 2008 - The British XAAR Corporation series nozzle inquired into that (1)
| British XAAR Corporation series nozzle inquired into spurts draws machine
profession integral development history short, the home spurts draws machine
manufacture manufacturer rushing headlong into mass action, created has spurted
draws machine the quality good and evil intermingled. It is well known, the
nozzle is spurts draws machine the heart, the user spurts in the purchase draws
a question nothing better than detailed inquiry which the machine-hour most
cared with the consultation related Nozzle primary device. At present in the
Chinese domestic market can see the nozzle divides property equally from Britain's XAAR
Corporation and US's SPECTPA Corporation. The nozzle is spurts draws machine
the heart, the domestic product machine applies the British XAAR Corporation's
nozzle at present. The overseas angel and the SKYJET UV Flat-bed Printer SKYJET Cylinder Digital Printer lake all spurt draw machine use
XAAR128 or the XAAR500 nozzle. The XAAR nozzle mainly divides into models and
so on XAAR128, XAAR500 and XAAR126. In view of the fact that XAAR128 and the
XAAR500 nozzle in the domestic widespread use, we mainly inquires into these
two kind of nozzles. The XAAR500 nozzle mainly has Wister, the Run river, the
branch water chestnut type use at present, overseas has not used the XAAR500
nozzle to spurt at present draws machine. The XAAR128 nozzle mainly has the
prestige Si Te, the elegant color blue, fly sail a boat and so on companies to
use; Overseas companies and so on lake, angel all spurt draw machine are using.
The XAAR500 nozzle applies most early in the printing profession, but the
XAAP128 nozzle is the application in spurts at the beginning of the development
draws the profession, therefore the XAAR128 nozzle is one section specialized
spurts at the beginning of the birth draws machine the nozzle. The domestic
certain companies or the consumer are mistaken XAAR500 are the XAAR128
substitutions The nozzle, this is obviously not correct. XAAR500 nozzle when
purchase must simultaneously purchase nozzle's drive, in the certain extent
increased the customer buys machine the cost, the XAAR128 nozzle as a result of
the internal subsidiary company, independently had already developed the drive.
On the one hand reduced has bought machine the cost, in addition On the one
hand is advantageous for the service and the replacement. The XAAR500 nozzle
outlook is big, each kind of color printing ink and four nozzle only
correspondences, if some nozzle damage, will cause not to be able directly to
spurt the picture, the XAAR128 nozzle will be the multi-nozzle design, each
kind of color's printing ink and many nozzle correspondences, will spurt solely
Head's damage may carry on the suitable atonement by other nozzles, has the
good atonement function. For example, the golden Hengfeng Wister 2908 model
nozzles from 8 nozzles to 24 nozzles are the XAAR128 nozzles, each kind of
color has 6 nozzles to correspond with it, single nozzle's damage nearly not
The influence spurts draws machine the work. Speaking of the speed, the XAAR500
sole nozzle spurts draws the speed is about XAAR128 nozzle's four times, but in
the practical application, the XAAR128 nozzle volume is small, the weight is
light, the price is cheap, the factory installs the several fold in XAAR500 is
the XAAR128 nozzle generally, therefore What the decision spurts draws machine
the speed is nozzle's total quantity. As soon as what needs to raise is the
XAAR500 nozzle replaces the cost is about probably each 25000 Yuan, but XAAR128
nozzle probably about 3300 Yuan. Generally speaking, two kind of nozzles in are
used both, but it is noteworthy that overseas spurts draws machine Existed not
one exception has used the XAAR128 nozzle, at present has not used the XAAR500
nozzle's import machine. The XAAR126 nozzle is XAAR Corporation's other model
of nozzle, in view of the fact that this model of nozzle in the domestic market
only then one, two companies uses, the XAAR126 nozzle and XAAR128 and the
XAAR500 nozzle does not compare the specially prominent place. Speaking of the
speed, the XAAR126 nozzle is the speed in Between XAAR128 and XAAR500.

| Where K = Ci × k, k for the ideal state of the friction coefficient, K =
(1 ~ 5) × 10-8 [mm / (N/mm2 m
/ min hr): 1, Ci = C0 × Cl × C2 × C32, bearing the pressure P usually refers to
the so-called load bearing pressure to bear load, the maximum load bearing
support area divided by pressure, the so-called pressure area, when the
cylindrical bearings, bearings from contact with some of the load The direction
of the projection area. 3, V bearing the speed of heat, mainly due to the role
of the friction bearings caused by the light of experience available, the
friction surface temperature rise, the impact of sliding speed V P much greater
than the impact of bearing pressure. This shows that the life span of the main
bearings from the value of P × V decision. At the same time bearing PV value is
determined by the heat. When the bearings operation, bearing temperature of the
heat generated by friction and heat affected distributed, Ceramic Bearing Electrical Insulating Bearing Self Lubricating Knuckle Bearing usually to a certain
temperature stabilized, if the ongoing operation in the invasion of impurities,
the performance of lubricating oil will be reduced, and because of the impact
of friction powder, Of fatigue, then the friction surface deformation that is
changing, increase the friction coefficient, bearing the temperature rise,
causing friction surface damage, resulting in charred, based on such a case, the
bearings, the lower operating temperature, that is, the use of low value of the
PV , Bearing the load of good, life extension, in the design, as far as
possible the use of the lower value of PV. Second, the design axis: (1), under
normal circumstances axis of material selection more than 35 # quality carbon
steel structure, may also join the alloying elements heat treatment improve
their performance, the transfer of materials, surface treatment, such as
hardening, the hardness of more than bearing hardness To receive more
satisfactory results when a hard object penetrated, the hard object can be
embedded in the bearings, shaft without injury, or else the shaft will reduce
fatigue life. (2), the surface roughness larger shaft, the shaft bushings and
the processes of the oil film will be cut off, resulting in direct contact with
the two. Therefore, improving the shaft surface roughness, as far as possible,
narrow the gap Film, to close lubricating fluid state, this can improve the
life of bushings, under normal circumstances axis of surface roughness in Ral.
6 above. (3), do not bear the load of alternating shaft plating, not only can
improve its corrosion resistance, and can effectively prevent the rough wear
and improve lubrication performance.
