Mechanical seals new materials and technologies1. Liquid seal: With the rapid development of polymer organic synthesis industry, the emergence of liquid sealant for electrostatic sealing; this new technology, often called liquid seal. The principle of liquid seal is the use of liquid sealant adhesion, mobility and monomolecular membrane effect (the larger the film, the greater the tendency of natu...

How to make mechanical seal storage and protectionA mechanical sealMechanical Seal Storage Environmental Conditions(1) air relative humidity below(2) temperature at 15 ~ 25 ℃(3) clean(4) well ventilated(5) to avoid direct contact with heat (solar and heat)(6) ozone and ultraviolet light, halogen lamp or fluorescent lamp), otherwise there will be brittle elastic material risk.2. Store about 2 to 3 ...

Kind of mechanical seals which is divided into several 1.push mechanical seal and non-push mechanical sealPush-type mechanical seal refers to the secondary seal of the mechanical thrust along the shaft or sleeve to compensate for the wear of the sealing surface of the mechanical seal, usually the spring-loaded mechanical seal.A non-push mechanical seal for secondary sealing is secured to the shaft...

Failure reason and Countermeasure of O ring(1) Installation damageInvalid condition: the part or all of the seal is in good order.Failure reason: the edge of the groove and other parts is sharp, the size of the sealing parts is not suitable; the hardness or elasticity of the seal is too low; the surface of the seal is polluted.Solution: clear sharp corners; groove design is more reasonable; choose...

Cause analysis and treatment of mechanical seal leakage1.Leak when static pressure test(1) when the sealing end face is installed, it is damaged, deformed and damaged.(2) when the sealing end face is installed, the cleaning is not clean, and the particles are covered with impurities.(3) the sealing face is not compressed due to the loosening of the positioning screw or the tightening of the gland ...

Analysis and treatment of vibration and heating of mechanical seal1.Static and dynamic ring end rough.2.The clearance between the dynamic ring and the sealing cavity is too small, because the pendulum causes the collision. Treatment method: increase the inner diameter of the sealing cavity or reduce the o...

Why every time the rubber bellows are removed from the pump, the seals are glued to the shaft?It should be vulcanized itself into a shaft so that it can drive the rotating surface.If you can easily delete it, it is wrong. You may have used the wrong lubricant on the rubber during the installation.This is the lubricant we use to attack rubber and expand it.

Can you customize it according to the mechanical seal I now use ?Of course, we are professional supplier of mechanical seal, we have professional technical team and after-seals service team.

What are the common causes of component damage?Mechanical damage - eg: seal face damage due to excessive loads caused by high pressure and damage to faces and other parts caused by incorrect fitting.Corrosion and chemical attack -eg: crevice corrosion or pitting of metal parts due to exposure to excessive levels of chloride , H2S, etc. or cracked or swollen elastomeric o-rings due chemical incompa...

What are the common causes of mechanical seal failure ?Mechanical seal failures typically fall into three main categories:Incorrect operating an process upsets or changes.Incorrect fitting and alignment.Incorrect (or not quite correct) seal system selection.The majority of mechanical seal fail. seal failures fall into the first category with more than 60% of failures being caused by some kind o...

What is considered a good service life for a mechanical seal ?If there are no other factors involved, then mechanical seal life is limited by how long it takes for the carbon face to fully wear .However , mechanical seals rarely wear out because of old age and usually fail due to some other reason well before the carbon wears excessively.There are many unknown factors that influence the actual ser...

What is considered good life for a mechanical seal?①The only part of a mechanical seal that is supposed to be sacrificial is the carbon face. The seal should run leak free until the carbon face is worn away. if the seal leaks for any other reason we consider it a premature failure and always correctable.②Two hard faces are selected when carbon is not acceptable in the application and you have run ...

What is a mechanical seal and how does it work？Mechanical seals are devices that control the leakage of fluid between a rotating shaft and the pressurised casing on rotating equipment. Mainly applications include centrifugal pumps, reactors, mixers and compressors.
