Q:What is mechanical seal?Single mechanical seal? Double mechanical seal? What's the shaft seal?
2. mechanical seal is a kind of rotating machinery shaft seal device. Such as centrifugal pumps, centrifuges, reactors and compressors and other equipment. Due to the drive shaft through the inside and outside of the equipment, so there is a gap between the shaft and the peripheral equipment, equipment in the media leak out through the gap, if the device internal pressure below atmospheric pressure, air leakage to the equipment, so there must be a package of the shaft to prevent leakage. There are many kinds of shaft seals, because mechanical seals have the advantages of less leakage and long service life
Q:What are the seals that are resistant to 500 degrees of high temperature?Airtight chamber gas temperature up to 500 degrees, what are the appropriate seals available? Thank you
Airtight container seals are static seal, you can use the "flexible graphite" material made of seals, capable of more than 1000 degrees high temperature. (dynamic seal does not apply).
Q:What is the maximum resistance to the seal in the hydraulic system currently being produced?
Therefore, in order to improve the sealing capacity, not only rely on seals, good structure is also very important. You say, if the light takes into consideration the seal, there is no problem with the regular 50MPa (usually around 30).
Q:What are the common sealing forms of hydraulic cylinders?
2, the friction ring seal on sleeve friction on the piston ring (made of nylon or other polymer materials) in O sealing effect of elastic ring under tight and cylinder wall to prevent leakage. This material is good effect, friction is low and stable, high temperature resistant, wear compensation ability, but the processing requirements, installation is inconvenient, suitable for high voltage and high speed or high sealing performance requirements. 3, the sealing ring sealing is to use rubber or plastic elasticity, so that a variety of sections of the ring ring attached to the static and dynamic between the mating surface to prevent leakage. The commonly used sealing rings are O, Y, V and so on. The utility model has the advantages of simple structure, convenient manufacture, automatic compensation after wearing, reliable performance, and can be used between the cylinder and the piston, between the cylinder head and the piston rod, between the piston and the piston rod, between the cylinder and the cylinder head.
Q:500 degree high temperature rubber sealing strip
For high and low temperature parts, insulation, pipe joints, etc.. Fluorine rubber - using the upper temperature limit of 300 degrees for chemical lining, advanced seals, high vacuum adhesive and so on.More than 500 degrees of high temperature, should have melted, can not be sealed role.
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:What are the uses and types of seals?
Seals can be divided into two categories: static seal and dynamic seal.Static seals are mainly gasket seal, sealant sealing and direct contact sealing three categories.According to the work pressure, static seal can be divided into medium and low pressure static seal and high pressure static seal. Low and medium pressure static seals are usually made of soft and wide width gasket. High pressure and static seals are made of hard material and metal gaskets with narrow width.
Q:The material of the seal must be compatible with the medium in contact with it. Why?
Therefore, the compatibility between them requires simple understanding that they do not react to each other in order to maintain their respective characteristics.
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.
Q:What's the function of the sealing ring?
Composition of mechanical sealMechanical seals are mainly composed of the following four components. 1. Main seals: moving ring and stationary ring. 2. Auxiliary sealing parts: sealing ring. 3, pressing parts: spring, push ring. 4, transmission parts: play skip and key or fixed screw.
