The Mechanical Parts DO Fail

We use clever design and parts like bearings to prolong the life of our mechanical equipment, but that’s not enough to save them indefinitely. Even if the immediate friction of metal on metal doesn’t kill something, there are other forces at work that will. It’s only a matter of time before something gives out in a big way.   Friction is STILL the Enemy Bearings let us reduce the friction between spinning parts, that way we don’t have metal grinding on metal inside motors, valves, vents, or anything else mechanical. That’s not where the friction ends though. Friction is literally everywhere. Whenever two materials touch, there will be friction, including between the air and water against an object. This is destructive. Air and water seem soft and safe to us, but they’re actually capable of being extremely destructive over time. This is most evident in pumps. The impellers spin and push the water around, creating movement and pressure. A new impeller will have precise, ‘teeth’, shrouds, that work direct the water like the blades of a fan. Over time however, the smallest imperfections will be worn into massive design failures. These shrouds will be worn down until they don’t trap, grab, and push water around anymore. They won’t hold up to pressure anymore. Overtime, the water is grabbing bits and pieces of the metal itself and just carrying it away. Any weaker parts of the pump will be eaten and […]

What’s the BIG Problem with my AC?

Every season there will be a fair number of people with small problems in their air conditioners. They’ll experience leaks, failed belts, and maybe a few minor electrical issues. These are all little wear and tear things that your contractor can fix for a few hundred dollars. When an air conditioner gets older however, things start getting a little more expensive. There can be some big things starting to fail.   Dead Compressor The compressor is that big, typically black, cylinder or spherical object in your air conditioner. In many ways it is the heart of the system. The compressor will receive refrigerant and through one of many ways, squeeze it down. This compression is what lets us remove heat from the air elsewhere in the system. When the compressor fails or begins to fail, you might experience warm air blowing from the air conditioner instead of cold air, regardless of temperature setting. The system may have difficulties starting up, draw excessive power, burn through fuses, or trip its breaker. When the compressor fails, there’s really only two areas things can go wrong: the motor or the compressor assembly. If the motor starts to go, it’ll perform poorly and draw more power to start and run. Eventually the motor will just get hot and stop cranking the compressor assembly altogether. At that point, it’ll probably blow a fuse and start melting internal components. On the other hand, there’s also a […]
