Q:How do you determine the assembly direction of the cylinder seals?
The lip of the cylinder seal is generally facing the direction of the oil pressure, so that it can play a sealing role in the work process.
Q:What type of sealing roller bearings.
The seal can be divided into two categories with seal and seal with roller bearings. The so-called bearing comes with sealing, that is, the bearing itself is made into a sealing device. Such as bearings, dust cover, sealing ring and so on. The utility model has the advantages of small space occupation, convenient installation and disassembly and low cost.
Q:What equipment is needed to produce rubber seals and what is the production process?,
Hello I made the seal! You do rubber ring to do large-scale (mixer, pre forming, opening machine, cutting machine, vulcanizing machine, trimming machine, testing equipment, there are many, I will not say!
Q:What are the equipment needed to produce the sealing ring?
These two are completely different materials, the rubber ring is generally rubber, PTFE is plastic, the production process is not the same. Not familiar with, or first learn more professional knowledge!
Q:What seals should be used for high speed spindle rotation?
What is the approximate temperature of your environment? Another is how much stress can be achieved Only in this way can you tell what material to use, or what form to choose, because you need to know the external use environment to determine the internal structure of the oil seal
Q:How are ceramic and metal sealed joint?
If it is static sealAxial, O ring or flat gasket can be used; radial O ring can be used.If it is dynamic seal, in addition to radial seal, but also consider whether the need for axial dust ring.The end face seal has a special sealing ring, and the lip is contacted with the ceramic surface.For reciprocating motion, a combination of O rings or other cross sections can be used.
Q:In the seal of hydraulic cylinder, the O-ring and Y ring are sealed well
It all depends.Minor changes in the shape of the same device in the same situation (environment)Its role will not be the same
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:How can the tapered roller bearings be sealed?
At the same time, we should pay attention to the proper use of seals, can bring great benefits; improper use of seals, the effect is not great. For example, the contact seal seal under high speed heating and rapid wear and loss of seal, wear products and pollution of SKF tapered roller bearing; non contact seal in the seal on both sides of a differential pressure (pressure or pressure), dust or as oil sealing effect will become worse.
