O – ring design knowledge set

Feb 06
2017

First, O-shaped rubber seal is a circular cross-section of the sealing element, it is widely used in a variety of mechanical equipment, at a certain temperature, pressure and different liquid or gas medium to play the role of sealing, and other seals Ring, has the following advantages:
①, sealing parts of a simple structure, the installation site is compact, and lighter weight.
②, a self-sealing effect, often only a seal will be able to complete the sealing Groove and compression
The compression ratio of O-shaped rubber seal for fixed seal is generally 15-25% (this data is the empirical data), 10 ~ 12% for reciprocating motion and 3 ~ 5 for rotary motion. % Of the compression rate, commonly used O-shaped rubber ring compression and groove size shown in Table 4-1-9 cnc drill effect.
③, good sealing performance, used as a fixed seal almost no leakage when used as a sports seal, only at higher speeds when some leakage.
④, the movement friction resistance is very small, also can adapt to the pressure change situation.
⑤, size and groove has been standardized, low cost, easy to use, easy to use and outsourcing.
Compared with other seals, there are the following three problems:
①, the starting friction resistance.
②, used as a pneumatic device seal, you must add lubricants to prevent wear.
③, the coupling parts, such as sports surfaces angle bending machine, grooves, gaps and other processing size and precision requirements are very strict.
Structural Design Principle of O – ring Rubber Seal
Because O-ring seals are used in a variety of trenches, the mounting trenches are listed in Table 4-1-3.

174944afgsbjpdjudsrrj1

Pressure and seal clearance
O-ring rubber seals are generally produced by the rebound of the compression to be sealed, but with the pressure increases, it is squeezed into the seal turbidity gap to produce a shape change, as shown in Figure 4-1

174944fezc5q7ex79scck5

In order to O-shaped rubber seal with a good seal and extend the service life, O-ring rubber seal must be installed groove and seal the gap between the design of appropriate, when the gap is too large O-ring rubber seal in the oil pressure Under the role of squeeze gap, causing damage, causing leakage. When the working pressure is less than 9.8Mpa generally do not design the retaining ring, when the pressure is greater than 9.8Mpa iron punching machine when the O-shaped rubber ring bearing pressure surface is easy to be squeezed out, should be added ring; if one-way compression in the bearing surface set a block Circle, if the two-way compression will have to set two retaining ring, as shown in Figure 4-2

O-ring performance standards

174945btaet99ykll4hqy3

The relationship between the hardness of O – ring and the maximum clearance and working pressure of groove
Sealing gap size and pressure levels, rubber hardness and O-shaped rubber seal section of the diameter of the relevant circumstances, see the following table:

Axial Groove Width and Depth of O – Ring Seals with Different Cross – Section
Axial seal groove width and depth; see Table 4-1-8 for axial seal groove width and depth

174947jb1duttieheupya3

The relationship between the hardness of O – ring rubber material and working pressure
In the rubber material standard, the hardness and compression set the most important performance of the two. Select the smaller compression deformation of the rubber material on the sealing performance is beneficial, and the hardness of the O-shaped rubber seal pressure and anti-squeeze is sheet metal punch essential. According to domestic standards and practical experience, the rubber at the specified temperature of the maximum compression deformation of not more than 50%. The hardness of the rubber and seal work pressure is closely related to the higher the pressure, the hardness is higher; see Table 4-1-11

174948t422bnj922in9j9j

Note: Rotary movement working pressure is generally not more than 0.4 Mpa, hardness selected in (70 ± 5) degrees; beyond 0.4 Mpa according to a special seal device design.
Groove finish requirements
The smoothness of the trench, the roughness of the trench contact surface, has a significant effect on the sealing effect and durability.
The surface roughness of each mating coupling groove of the seal groove

174948qzbuumqr4ds4snpi

Groove and compression
The compression ratio of O-shaped rubber seal for fixed seal is generally 15-25% (this data is the empirical data), 10 ~ 12% for reciprocating motion and 3 ~ 5 for rotary motion. % Of the compression rate, commonly used O-shaped rubber ring compression and groove size shown in Table 4-1-9

Interpretation of Growth Trend of Space Laser Used in Proximity Sensing

Jan 24
2017

NASA’s Goddard Space Flight Center (NASA’sGoddardSpaceFlightCenter), researchers are working to study the future of space flight and remote sensing instruments used in laser launchers, including for the ice cover and marine ice monitoring micro-pulse laser altimeter, A laser spectroscopy instrument for atmospheric carbon dioxide detection, and a laser imaging radar for high-resolution imaging of the Earth’s surface cnc punching machine. In addition, these flying loads can also be used for the detection of the atmosphere of other stars in the solar system and for the imaging of the stars cnc machining center. In this paper, we first summarize NASA’s previous space-borne laser-borne launchers for Mars, Mercury, Earth and Lunar Orbit, and then synthesize the current space flight laser load projects, and introduce their science of proximity sensing And to explore the use of the expected results.

 

There are three laser loads in use today, and their mission is to use scientific data on the Earth induction welding, Moon, and Mercury so that we can more deeply understand our planet and the solar system. All of these radar systems use a semiconductor laser array-pumped high power quasi-persistent solid-state laser as a light source. The first solid-state laser pumped on-board semiconductor laser was the Mars satellite laser altimeter, which was launched in 1996 and provides a large number of high-resolution Mars profiles. Subsequently, in 2003, a laser altimeter was launched for earth sciences research. The laser load currently in use is the cloud-aerosol orthogonal polarimetric lidar, the Mercury laser altimeter, and the lunar satellite laser altimeter, which was launched in 2006. Although the current semiconductor-pumped solid-state lasers in space has made great success, but still can not meet the requirements of future laser radar. Therefore, it is necessary to develop a new type of space laser for future proximity sensing.

Punch load noise is really annoying

Dec 26
2016

The causes of load operation noise are caused by tool and workpiece or stripper plate and blank impact milling drilling machine, stamping process of twisting and punching Drilling Machine for Plate. One punch stamping process of punching and torsional noise the largest noise. \t1. Punching shear noise. Stamping process different, very different noise. Sheet blanking than bending, deep drawing noise. The punch press, pressure wave, flanging, bending, drawing and other forming process noise is small. \t2. Punch noise. Torsional noise of the same type of punch press parts with the thickness, hardness, geometry, hammering speed, die clearance and other factors, the noise increases with these increases.

Punch work, the punch and the plate and the discharge plate and blank impact impact greatly enhanced Structural Steel Fabrication, with the impact of the impact speed also increased. The collision noise of the punch and the subsequent fracture sound of the material can be measured separately, and this measurement method has been implemented. In the same punch, punching thick, hard material than the punching thin, soft material noise. For thick ductile sheets, the impact noise is the same as the fracture sound.
