- Q: What is mechanical seal?Single mechanical seal? Double mechanical seal? What's the shaft seal?
- 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. "
- Q: What are the uses and types of seals?
- Dynamic seals can be divided into rotary seal and reciprocating seal two basic types.According to the seal of the relative movement of the parts is divided into sealing contact, contact and non-contact seal; according to the seal and the contact position can be divided into circumferential seal and the seal, the seal is also called mechanical seal. The centrifugal seal and spiral seal in the dynamic seal are sealed by the power of the medium when the machine is running, so it is sometimes called the power seal.
- Q: What's the difference between an oil seal and a seal? Is it the same thing?
- The seal is a general term for all products that are sealed. They include O rings, oil seals, seals for piston hydraulic cylinders, dust rings, and so on,
- 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: The cylinder seal includes what ah, I heard a small piston ring of YX2, D2, D2, dust 2, O ring 2, a total of 8 as a set of individual is D1, D2, dust 2, O ring 2 a total of 6 pieces a.
- Piston rod seals: piston rod dust + piston rod seal (these two can be combined into one, which is also more commonly used), piston rod buffer, piston rod guide support ring;
- Q: Want to ask, vacuum seals can use what glue to fill, can achieve the purpose of high vacuum, the material is metal, thank you
- 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: How do you determine the assembly direction of the cylinder seals?
- According to the sealing direction and the pressure direction of the cylinder to determine, usually in relative direction
- Q: What are the material requirements of the valve sealing surface?
- Sealing materials should meet the requirements of sealing function. Due to the different sealing medium and different working conditions of the equipment, sealing materials are required to have different applicability. The sealing material requirements are: the material density, not easy leakage; the appropriate mechanical strength and hardness; and good elasticity, compression, permanent deformation is small; the high temperature softening, decomposition, low temperature, non hardening embrittlement; the good corrosion resistance in the long-term work of acid and alkali, oil medium, the volume of a small change in hardness, and adhesion to the metal surface; the low friction coefficient, good wear resistance; with the sealing surface with soft and full; the good anti-aging, durable; to facilitate manufacturing, price cheap, easy. Obviously, it is impossible for any material to meet the above requirements completely, but the material with excellent sealing performance can meet most of the above requirements.Rubber is the most commonly used sealing material, in addition to rubber, suitable for sealing materials as well as graphite band, PTFE and various sealants, etc. table 29.2-4 lists the classification and use of sealing materials.
- Q: What are the common materials of rubber seals for valves?
- Construction machinery industry, shipbuilding industry, automobile manufacturing, hydraulic industry and so on, almost as long as there is a place where the machine will use the oil seal oh.
- Q: Classification of the use of seals
- The seal according to the shape and material type, sealing structure, sealing mechanism, classification of seal for 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 axis. 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. To this end, often on the packing pressing degree of adjustment, so as to fill in the lubricant after running for a period of time loss, and then squeezed out some lubricant, pressing force relaxation while compensating for volume changes caused by filling.
