Q:What are the uses and types of seals?
According to the type of sealing structure, sealing mechanism, seal shape and material, the classification of seal is:Packing into the packing cavity after the gland axial compression on it (see figure 29.5-9), when the filler and relative motion, because the plastic filler to produce a radial force, and close contact with the shaft. At the same time, the lubricant impregnated in the packing is extruded and an oil film is formed between the contact surfaces. Because the contact state is not uniform, the contact parts will appear the boundary lubrication condition, known as the "bearing effect"; the concave without contact to form a small oil tank, oil film thickness, contact and non-contact parts of an irregular maze, preventing the liquid leakage flow this effect, called "labyrinth effect". This is the mechanism of packing seal. Obviously, the good seal is to maintain the "bearing effect" and "labyrinth effect"". That is to say, to maintain good lubrication and proper compression. If the lubrication is bad or pressed too tight, the oil film will be interrupted, resulting in dry friction between the packing and shaft, and finally lead to burning shaft and serious wear and tear.
Q:Design of sealing ring, groove and bottom fillet of sealing ring
Hello, Lei Xin sealing ring, the outer corner of the groove of the sealing ring is designed to prevent the scratch of the O ring assembly. It generally uses a smaller rounded radius, that is, r=0.1~0.2mm. This avoids the formation of a sharp edge, the O ring does not dare to squeeze out the gap, and can make the retainer stable
Q:National standard for mechanical seals
There are many kinds of seals in the machinery industry. It is recommended to inquire about the standards required by the GB website.GB 10444-1989 mechanical seal product model method, China Machinery Industry Federation 1990-01-01 currentGB/T 10708.1-2000 reciprocating rubber sealing ring structure size series first parts: one-way sealing rubber ring, the State Quality Supervision, inspection and quarantine. 2001-03-01
Q:So in today's world, mechanical seal is the most important shaft seal in these equipment. The mechanical seal is also called the seal, in the relevant national standard is defined as: "by at least a pair of end faces perpendicular to the axis of rotation of the fluid pressure and the elasticity of compensation organizations (or magnetic) device and the role of the coordination of auxiliary seals to keep up with the relative sliding to prevent fluid leakage. "
Type (translation should also be stamped), and also can be Chinese and translated in the same form of paper.I hope the students will check with their school as soon as possible, and whether they can issue such documents. If you can't, then go to the notary office. F+U representative office can help the student to submit the notarization to the audit department and help the students get the notarization quickly.In addition, we should also communicate with the University as soon as possible, if you need to notarized, then through the audit or, if the time is urgent, we must seize the notary office to add legalization.
Q:What kind of performance requirements should the rubber seals meet?
physical propertyThe seal is generally divided into static sealing and dynamic sealing in two forms, one of the typical example is the static sealing pipe sealing, after installed in the pipeline, the pipeline movements will cause the rubber seal (circle) and slow motion interface, while the rubber is in the static state of compression. Because most of the pipeline buried underground, so some outside factors such as temperature, ultraviolet radiation and other basic oxidation on aging seal has no effect, at this time of the rubber material can require a higher compression performance, others can reduce the requirements; a movable seal used in the process of rubber seal should have different physical properties. The representative of the dynamic seal valve seal, the sealing process, the addition of rubber stress, the surrounding environment is complicated, so the rubber seal in the process due to excessive squeeze decreased elasticity, or because of wear caused by leakage. Therefore, in this process, we must according to the seal between the valve sealing parts in the process of the use of different materials used require different physical properties, and effectively solve the rubber seal and deformation, because of the long-term use of sealing effect reducing problems.
Q:On the amount of compression of the sealing ring
Fluorine rubber heat resistance, oil resistance, chemical corrosion resistance, good aging, suitable for high temperature (-25~240), vacuum, the use of chemical medium, not suitable for the use of ketone, ester
Q:About hydraulic cylinder sealing ring What is the model of the general oil cylinder seal ring and what is its selection principle?
(3) the sealing ring has the advantages of strong corrosion resistance, aging resistance, long service life, good wear resistance, and automatic compensation to a certain extent after wearing.(4) the structure is simple, the use and maintenance are convenient, and the sealing ring has longer service life.
Q:What kind of equipment do you need to open a small seal factory?
1 rubber machines, 2 cutting machines, 3 vulcanizing machine tools, 4 ovens (if you do fluoride products)
Q:Would you like to ask what glue can be used for vacuum seals?
The sealant can resist high temperature, corrosion, vacuum to achieve, you can check online, Varian was acquired by Agilent, do not know not to change the name! But for vacuum seals, there should be no problem!
Q:What are the categories of commonly used hydraulic seals?
The most common are the O ring, the shaft seal, the lip ring, the collar ring (the O-ring), the combination seal, etc. all other seals are these sealed deformations.
