Excessive heat can adversely affect the mechanical seals you are using. It can hasten its deterioration and can break it down easily in time. This can result in leakages and can be harmful if you are dealing with toxic chemicals in your plants.
Factors to Consider When Choosing Mechanical Seals Mechanical seals are always present in any construction project that uses machines with rotating shafts and connections. While these parts are often overlooked, picking out a mechanical seal is something that should be given ample time considering the different factors that usually come to play at this. Some manufacturers may discourage the use of mechanical seals mainly because it is more expensive compared to other alternatives like gaskets and gland packing. When in use, seals can usually last for a few months or even up to a full year. Despite this, it is still relevant to know some of the things that easily wear out the seals you are using. Overheating is one of its biggest problems. Excessive heat can adversely affect the mechanical seals you are using. It can hasten its deterioration and can break it down easily in time. This can result in leakages and can be harmful if you are dealing with toxic chemicals in your plants. Its seal faces. It can result in the seal sticking to the machine or any other installation it is being used with. Seals with carbon-graphite faces are especially vulnerable to this. Those with plated faces, on the other hand, can crack. Some seals may be deformed due to too much heat absorption. This can lead to a number of problems including premature leakages. The fillers used in some seals can also melt or corrode at very high temperatures. Overheating can be caused by improper installations on the plant itself. This is why it is very important to deliberate and decide the specific mechanical seals that should be used before proceeding with your purchases. There may be inefficient cooling systems in your machines or inefficient cooling jackets that will result to overheating. The problem can also be traced to the people maintaining the installations or machines. Mechanical Seals Requirements There are several factors to consider when choosing mechanical seals. You do not want to waste too much of your resources in buying the wrong seals for your project. You need to set down and make a list of the specific parameters that the seals will have to conform to and withstand. Speed of the machine and the frequency of use is the first thing that you need to consider when choosing mechanical seals. Mechanical seals come in different shapes and sizes and you need to consider which among the myriad types you need. For machines that operate at 5000 feet per minute, for example, you can opt for a rotating seal. If the assembly that the seals will be installed in exceeds this, then a stationary mechanical seal would be the better choice. Pressure is another factor that needs consideration. Manufacturers usually put the specific maximum pressure that their products can withstand. Take note of these and make sure that you apply the seals in machines that operate within the specifications. Temperature, as was discussed above, is also significant. Lastly, motion capability is another factor in this list. Pick mechanical seals according to the aforementioned factors.
