Closely related to the raw material and product quality rubber seals
Raw material quality rubber seals are closely related to the reliability of the final product. Common problems are: inconsistent quality of raw materials, when raw rubber mixing vote wrong, improper storage of raw materials or mix (cross-contamination), rubber mixing uneven curing conditions (temperature, time, pressure, etc.) is wrong, seal products improperly stored, improper use of molds. These issues are often related to the production process quality control. When choosing the ordering side seal manufacturers, should after several visits, research and product testing. In the delivery process, the seals may also require the company to provide true, accurate inspection reports. [View Details]
How piston rubber O-ring is not worn
Replacing some of the control valve, the fault is not eliminated. After dismantling the cylinder piston found serious rubber O-ring, so that the cylinder two-chamber hydraulic oil due to mutual channeling. Analysis of the reasons, since the rubber O-ring wear, cylinder rod chamber and the rod chamber gap increases interoperability, when you close the control valve shut-off valve 2 or 3, it means cutting off the cylinder rod chamber of the return line.

Experimental hydraulic friction O-ring
Hydraulic friction characteristics of the O-ring seal is an important issue concerns research. Hydraulic O-ring at different compression ratios suffered friction. Movement, ensure concentricity between the rod and the hydraulic friction O-ring and O-rings between the hydraulic friction lever mounting position leaving a gap in order to avoid friction between the two, four stages were measured hydraulic O-ring of the forces: friction rod starts moving stage, the friction rod uniform motion stage, the friction arm stop motion without unloading the cylinders driving force uninstall the driving force of four stages, and thus can be a detailed analysis of the movement patterns of the entire reciprocation O-ring . Domestic and foreign scholars on the [View Details]
Xinhua Xu vulcanization process of rubber gasket
Xinhua Xu vulcanized rubber gasket is through chemical cross-linking between rubber molecules will be substantially converted to plastic raw rubber elastic and dimensionally stable product, the physical properties of vulcanized rubber stable, extended temperature range. "Vulcanization (Curing)" the term commonly used throughout the rubber industry, plays an important role in rubber chemistry. Vulcanized rubber molecular chains [View Details]

Rubber seals how rational selection scheme
1, at room temperature, low pressure, the selection of rubber seals; when the pressure high-temperature, use a combination of metal and non-metal or rubber gasket seals; temperature, pressure greater volatility, the selection of good flexibility or self-tightening rubber seals; at low temperature, corrosive media or vacuum conditions, it should consider sealing gasket with special properties.

Suitable amending the law of the rubber O-ring
Unvulcanized rubber O-ring compound as a viscous fluid, and the compression molded and cured stage, plastic materials quickly to fill the cavity at a high temperature, pressure, the excess part (in order to prevent lack of glue, filling in the cavity of the rubber material, certainly to maintain a certain excess) overflow vulcanization, they formed the excess glue (also known as scrap, flash). Overflow edge once formed, to make the appearance neat and beautiful, must be removed, this process commonly known as trimming. For trimming the size requirement is precise, neat appearance. In the actual production. Trimming products are often time-consuming, consuming work, strict requirements for the product, when trimming a slight mistake which may waste time and must be treated with caution. Generally speaking, the smaller the size of the product specifications, the more complex configurations, the higher the difficulty of trimming, the more waste. [View Details]
Working condition Hydraulic O-rings
Hydraulic O-ring seal is the easiest and most common type is one of a wide range of static and dynamic applications. O-ring groove design of hydraulic O-ring is relatively simple - a groove shape by the developed rules to obtain an economical and reliable sealing. Basically, an O-ring seal is of circular cross-section into a resilient O-ring groove design, there is provided an initial compression. O-ring hydraulic compression force required to cross-sectional diameter and hardness results. Stretch the O-ring by reducing the cross-section, which reduces the potential impact of the sealing O-ring seal compression. [View Details]
Hydraulic silicone rubber O-ring PRECAUTIONS parked ripening time
Hydraulic kneading silicone O-ring in accordance with the requirements of the specimen thickness showings must be cooked into after showings, hydraulic rubber O-rings deposited in the warehouse, on a flat, clean, dry metal plate is cooled to room temperature (efficient management methods Make rubber is deposited on the trolley to move freely), and then at 23 +/- 2 ? condition, parking 22-24 hours, and to prevent moisture absorption. Silicone back when needed refining, refining shall return roller pitch, roll back requirements mild refining time will be. [View Details]
