Sealing Ring Stable Performance, To The Machine To Bring High Capacity

With the seal industry more and more advanced technology, people slowly found that a normal work of the machine, in order to its production capacity and high efficiency, than to have a good equipment. And for the seal, the quality of good or bad really affect the use of the mechanical efficiency of it. If the seal performance is stable, then you can bring high productivity to the machine, if the seal is not good quality, it will bring losses to the work.
With the upgrading of technology, people slowly divided into several types of seals, summed up can be divided into three types: low-end seals, mid-range seals, high-end seals. Of these three types, the cost and price of the low-end seals are the lowest, but the quality and service life are also the shortest. The high-end seal is the best seal in the seal industry, but it is expensive and costly. In the end of the ring is to take its two strengths for a seal, the cost is neither too high, the quality can be guaranteed, so slowly to replace the low-end seal market, a seal industry's mainstream products.
The advantage of the midrange seal relative to the low-end seal is that the service life is greatly improved, saving a lot of maintenance costs, and greatly improving the mechanical capacity, but the price is not much lower than the low-end. Overall calculation, with the end of the Sealing Ring products than the low-end seal products to cost-effective.
Although the carbon seal has some well-known shortcomings, it is still a standard part of a universal steam turbine seal. The primary problem in the shortcomings is that the inner ring of the seal is prone to wear, the shaft clearance is increasing, and the steam leakage is becoming more and more serious, resulting in the need to replace the carbon seal on a regular basis - frequently changing 4 times a year.
The carbon seal is simple to install and costs less than $ 1,000, so the cost of keeping the seal with a carbon seal does not seem to be high. However, carbon seals are prone to wear and may break, and there are also costs and costs associated with these problems, including higher water charges due to steam loss, and due to oil contamination and higher operating temperatures Resulting in reduced bearing performance.
For operators wishing to reduce steam leakage and improve equipment reliability, there are two major alternative options for the carbon seal on the market: mechanical seals and Sentinel floating brush seals.
O-shaped rubber seal ring is a circular shape of the Sealing Ring element, it is widely used in a variety of mechanical equipment, in a certain temperature, pressure and different liquid or gas medium to play a Sealing Ring role, and other seals Ratio, with the following superior performance:
①, sealed parts of the structure is simple, compact installation, and lighter weight.
②, self-Sealing Ring effect, often only one seal will be able to complete the Sealing Ring effect.
③, good Sealing Ring performance, used as a fixed seal when almost no leakage, used as a sports seal, only when the speed is high when some leakage.
④, movement friction resistance is very small, for the occasion of the pressure can also be adapted.
⑤, size and groove has been standardized, low cost, easy to use, easy to use and outsourcing.
Compared with other seals, there are three problems:
①, starting the frictional resistance.
②, used as a pneumatic device seal, you must add lubricating oil to prevent wear.
③, the coupling parts, such as the moving surface, grooves, gaps and other processing size and accuracy requirements are very strict.
