Q:What kind of seal is the dust sealing ring?
The dust ring is mainly used in hydraulic piston rod above the start, it is the role of the piston cylinder outside the dust to clear, avoid some particles inside the cylinder liquid and other contaminants penetrating sealing, improve sealing performance.
Q:How should the piston rings for piston wear be chosen? What is the national standard?
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.Three, SIL silicone rubber sealing ring: with excellent heat resistance, cold resistance, ozone resistance, atmospheric aging resistance. Has good insulation performance. But the tensile strength is inferior to that of ordinary rubber and has no oil resistance. Applicable to household appliances, such as electric water heaters, electric irons, microwave ovens, etc.. The utility model is also suitable for various articles which have contact with human bodies, such as a kettle, a water dispenser, etc.. Not recommended for use in most concentrated solvents, oils, concentrated acids, and sodium hydroxide. The general use temperature range is -55~250 degrees centigrade.
Q:What's the difference between an oil seal and a seal? Is it the same thing?
The oil seal, also known as the rotary shaft lip seal, is a seal used in the rotation of the shaft. It is different from the seals used for reciprocating movement of the piston!
Q:The difference and advantages and disadvantages of single lip seal and double lip seal
Ring seal generally refers to the buckle ring seal, the material is divided into metal and non-metallic. Common metals are mostly used in reciprocating motion.Lip seal generally refers to the outsourcing metal skeleton lip seal, metal and non metal lips, applied to rotary motion.
Q:Reasons affecting the tightness of cylinder
1, piston and cylinder clearance2, piston ring end clearance3 、 piston ring backlash4 cylinder cylindricity5, valve tightness
Q:What kind of seals are divided into?
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: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: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:Excuse me, what's the material for the general piston ring?
application areaBecause of the above properties, PTFE is widely used in chemical machinery, electrical, electronic, metallurgical, defense aerospace, instrumentation, metal surface treatment, pharmaceutical, medical, textile, food and other industries, to become irreplaceable products. 1., filled with PTFE bearings, used in food, chemical, paper, textile machinery;
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.
