FAQ

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
What are the storage conditions for seals?
First of all, the pressure is an important factor affecting the quality of seals, the pressure level, the length of the pressure cycle cycle, the seal damage (such as extrusion) have a great impact. The higher the pressure, the greater the influence of other factors on the performance of the seal, such as temperature, speed, the material of the seal, the clearance between the piston and the cylinder, the clearance between the piston and the cylinder head.Another is the temperature and friction, it is difficult to describe the maximum use temperature and minimum use temperature of a sealing material, because it is the result of a series of factors. The piston and piston rod have different operating temperatures, so we should choose them differently. Another is the seal product surface roughness, surface characteristics, pressure, medium, temperature, sealing materials, seals type and speed of movement, these are the factors affecting the seal.The last is surface treatment. Experience has shown that the characteristics of the surface of the cylinder piston and the piston rod have a great influence on the life of the seal. Surface characteristics are defined by the values of surface roughness RA. RA is the arithmetic mean of the shape of the surface deviating from the absolute value of the center line. However, these values do not fully indicate the effect of surface conditions on the seals, because even under the same roughness, different surface shape features can cause wear of seals to varying degrees of seal.
What rubber kind of rubber does the brake seal of the car use?
People have encountered such a problem in production: a customer asked him to produce a number of cars on the brakes with seals, resistance brake oil, swelling can not exceed 2%, shore A60. hardness he used nitrile rubber production, detection of customers to pay customers after that swelling failed, he was replaced nitrile rubber grades with nitrile rubber and butadiene acrylonitrile production in 42% and merged with pVC, is still not qualified. This puzzled him.
What is the sealing principle of O type sealing ring?
The O ring has good sealing performance. It can be used for both static and dynamic seals. It can be used not only individually, but also as a basic component of many modular seals. It has a wide range of use. If the material is chosen properly, it can meet the requirements of various media and various sports conditions.
How long will it take for the seal to age naturally after the seal has been installed on the cylinder?
This is a lot of factors, first look at what brand of sealing ring! Good brand in a certain environment, aging slow!
About the service life of hydraulic cylinder sealing ring
Haha, the inside of the injection molding machine or digging. Mechanical arm?.OK, OK on the market is a good one, is not ideal, relatively better, that is when others do use a standard material, without reducing scrap material cost.
What type of sealing roller bearings.
The so-called bearing additional sealing performance device, that is, in the installation of end caps and other internal manufacturing into a variety of sealing devices. On the selection of roller bearings with a sealing Longma Xiaobian that should consider the following 6 main factors.
How do you determine the assembly direction of the cylinder seals?
Look at your choice of sealed form, two-way sealing products do not have to consider the direction of installation, but some lip products, such as Y ring, we should consider the direction of the lip and the direction of the oil pressure coordination
