Q:Who knows, the country has a few sealing strip production enterprises are more concentrated place
Glass bead, glass glue, glass of water, glass door seal rubber molded parts, mechanical seals, foam seals, seals, gaskets, rubber pad, three EPDM rubber molded products, silicone, transparent, dustproof, rubber (PVC), white, various types of color. All kinds of rubber, silica gel, rubber and plastic, three yuan ethylene propylene (EPDM) system
Q:How to choose the sealing ring according to the shaft?
General hardness is chosen according to pressure, low pressure with low hardness material, high hardness with high pressure. According to the load type can be divided into static seal and dynamic seal. According to the sealing use, can be divided into hole seal, shaft seal and rotating shaft seal
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:About hydraulic cylinder sealing ring What is the model of the general oil cylinder seal ring and what is its selection principle?
Sealing ring advantages:(1) the sealing ring should have good sealing performance in the working pressure and the certain temperature range, and it can automatically improve the sealing performance as the pressure increases.(2) the friction between the sealing ring and the moving parts should be small, and the friction coefficient should be stable.
Q:What is the material of the sealing ring mostly?
Two, HNBR hydrogenated nitrile rubber sealing ring: with excellent corrosion resistance, tear resistance and compression deformation characteristics, ozone resistance, sun resistance, weather resistance better. Better abrasion resistance than nbr. The utility model is suitable for washing machines, automobile engine systems and refrigeration systems using new environmental protection refrigerant R134a. Not recommended for use in alcohols, esters, or aromatic solutions. The general use temperature range is -40~150 degrees centigrade.
Q:How to prevent the metal from sticking to the gasket?
It is better to use torque wrench when sealing gasket is pressed. For large bolts and high strength bolts, it is better to use hydraulic tightening devices. The tightening torque shall be calculated by calculation according to the given gasket. The size of the hydraulic pressure of the hydraulic tightening device shall also be determined by calculation.5. When installing the gasket, tighten the nut in sequence. However, the design value should not be screwed once. Generally should be recycled at least 2~3 times so that the gasket can be evenly distributed.6, the flammable and explosive medium pressure vessel and piping, replacing gasket should be used to avoid security tools, tool and flange bolts or collide, sparks, causing a fire or explosion accident.
Q:How are ceramic and metal sealed joint?
The sealing parts should be selected according to the different line speed, sealing medium, temperature, pressure and direction.
Q:What kind of seals are divided into?
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:Design of sealing ring, groove and bottom fillet of sealing ring
The rounded corners at the bottom of the groove are mainly designed to avoid stress concentration. The value of fillet radius, dynamic sealing groove desirable R=0.3~1mm, static sealing groove, it is recommended that its O ring section diameter of half, that is R=d/2
Q:Is it good to use NBR or EPDM for sealing parts?
NBR produces industrial rubber products exposed to mineral oils, liquids, and gases
