Designing a Futuristic World and a Brighter Future

Mechanical engineering is an exciting career options that touch upon various facets of designing and production of tools and mechanical equipments, used in industries. There is an impressive line up of options to match your skill sets and interests. Without the advent of mechanical engineering the world would have been an archaic place to live. From thermal power stations to jet machines and combustion tools, mechanical engineering deals with almost all segments of our daily lives.

Mechanical engineering is one of the oldest disciplines and the second largest in this filed. Mechanical engineers would be applying principles of mechanics in designing various machines and devices that would make the life simple and more efficient.

In case you are interested in making engineering as your profession, you should take a degree in mechanical engineering where you would be learning about the design, operation and maintenance of various types of machines and their components.

Mechanical engineers are in demand in various well paid segments like automobiles, space centers, trucks, airplanes, and trains among others. They would also be dealing with many other useful activities like the economical combustion of fuels and the application of mechanical energy to do various tasks. The job profile of a Mechanical Engineer can be extremely challenging as it requires high end analytical and IT skills apart from interpersonal skills to work as a team. They would be required to work in adverse conditions like high temperature and amidst high noise levels of machines. They would also be dealing with financial and management professional while designing new products while analyzing their marketability and financial viability. They would be responsible to see that the plant is operated smoothly as per the design and plan and that the machines are properly maintained.

Mechanical Engineering offers a strong base for professional engineering practice, and in many other related segments. Students should have good analytical skills and logic to come up with innovative designs and creative ideas that would enhance the quality of life. Mechanical engineers would be required to work for long hours and also in night shifts if they are working on time bound projects like space shuttles. The deadlines and work pressures would be immense and they should not crack under pressure. The salary and perks are one of the best industry and proficient candidates would be able to climb up the career ladder easily as there are many disciples and career options in this vast field.

Design Problems and Maintenance

A List of Possible Design Problems of Mechanical Seals

When working with mechanical seals, you want to maintain their usefulness and good performance so that you’ll receive great results. One way to make sure mechanical seals stay in good shape is by checking design problems. Even a small defect in your sealing equipment can cost production and operation dearly.

Here’s a quick guide on mechanical seal design and maintenance problems.

Issues with Faces of Mechanical Seals

Selecting the wrong hard face or carbon seals can have negative effects. The material may turn out to be incompatible with the chemical or liquid you’re trying to seal. The solvent, cleaner or flush system may also not work.

Problems with Face Flatness

If the face cross portion is way too narrow, the seal will experience pressure or temperature distortion problems. To prevent this distortion, the clamping forces should be “equal yet opposite.”

Weak Heat Conductivity

Compared to seals made of other materials, such as hard face seals, carbon is a relatively poor heat conductor. Plenty of other ceramic items are weak heat conductors. If you’re going to use carbon, the material should be dense enough as to prevent the expansion of air pockets and the formation of pits within the carbon face. Additionally, the best option would be unfilled carbon that has four impregnates.

Springs and Bellows

Springs found in the liquid can easily clog, especially when small springs are used. There’s also the problem of chloride stress corrosion in stainless steel bellows and springs.

Small cross sections of springs and thin bellow plates are considerably probe to abrasive wear, and you also want to be careful when winding a single spring because winding it in the wrong direction can cause damage.

Also, be careful with rubber bellows because when the bellows rupture, a disastrous failure is sure to follow.

Metal bellows and springs are more exposed to high stress, and stressed metals experience corrosion and fatigue faster.

Severe Operating Conditions

It shouldn’t be a surprise that extreme temperatures hasten damage in industrial equipment. Although industrial materials are continually being developed to resist severe temperature ranges, elastomers and several other seal faces are quite prone to damage from excessive heat.

Too much pressure can also deform the seal faces and case extrusion to the elastomer.

Although mechanical seals tend to be exposed to high speed because of rotating seal designs, a great deal of heat can lead to the seal faces overheating. A lot of movement can also cause the shaft to break apart.

Other Design Setbacks

Among other problems, the majority of seal faces tend to be weak in tension.

To preserve the effectiveness of seals, they should be packaged very securely because storage and shipment can be very hard on these devices.

If the application calls for high speed and lots of movement, consider using mechanical seals with a stationary design.

No matter how strong the material used to make sealing equipment, mechanical seals are bound to deteriorate at some point. However, there is something you can do about delaying their deterioration. With this guide, you’ll be able to target the weakness point of mechanical seals, and take better care of them.
