Bearings have found to be very effective in the prevention of damage by earthquakes. They provide the capacity to withstand earthquakes, an example of which is the San Francisco airport.
Electric pumps can be affected by high winds. Not only can these winds cause defrosting problems, they also blow debris into vents and can even cause overheating and motor blowouts. Try to secure them away from areas where high winds could cause trouble.
According to the American Bearing Manufacturer’s Association, Leonardo Da Vinci described and designed a type of ball bearing in the 15th century. It was the industrial revolution though that saw great advancements in technology, allowing different types of bearing designs to meet different needs.
Electric motor facts: Did you know that so many of the objects we use every day contain electric motors? Dishwashers, microwaves, and electric can openers are just some of the kitchen items that contain electric motors.
The easiest way to tell you need new (ball) bearings is noise! In fact, bearings will reveal their need for changing with an increase in noise levels, which is often accompanied by an increase in temperature and a corresponding decrease in running accuracy.
Have you ever heard “loss of prime” in reference to a pump? This loss is usually due to air making its way into the pump and will require the pump to have liquid added or be “primed.”
In a ball bearing, the ball is a sphere that spins very smoothly by contacting the inner and outer race of the ball. If the load is too heavy, it can squish or deform the balls and ruin the bearing.
Electric motors are often used in rotating machines such as turbines, fans, drills, locomotives, and conveyor belts. They are also useful in robotics, and are currently being used to replace hydraulic cylinders in airplanes and military equipment.
Some of the largest ball bearings are used in earthquake-prone areas. Buildings are made with ball bearings in their foundations to allow movement without fear of structural damage.
Never pump anything that could be considered flammable or corrosive. Even if thoroughly cleaned, it could easily catch on fire in the future.
Did you know that the tolerance of the bearing is an important factor to be considered when buying it? It is this level which decides the amount of expansion of the bearing upon heating.
The most prominent feature of centrifugal pumps is that they have one or more impellers. Centrifugal pumps are used with all kinds of liquids (clean or dirty), as they have the highest flow rates of all pump types.
Did you know Conrad bearings can withstand both axial and radial loads? Unfortunately, they also have a lower load capacity due to the limited number of balls within the assembly. Conrad bearings are still widely used in the mechanical industries.
Q: My AC electric motor doesn’t seem to be starting. What could the problem be? A: A number of things might be wrong. You could have a blown fuse or a broken hookup wire, for instance.
Giant ball bearings five feet in diameter are just some of the building technologies the San Francisco International Airport has incorporated to help the structure survive earthquakes.
Is your motor making a lot of noise when it doesn’t normally? This could be caused by bad bearings, loose mounts, or misaligned couplings. Take a look at these, replace or tighten anything that looks off, and see how you go.
How many drivers do you think actually consider what would happen if the steering on their car suddenly failed? A car’s steering system is one of the components that must, and does, function safely and reliably throughout the whole life of a vehicle, thanks in large part to proper fitting bearings.
The first locomotive with an electric engine was made by a scientist called Charles Page. The project was paid for by the US Senate in its quest to drive expansion via rail.
Henry Timken patented the tapered roller bearing in 1898. He was a 19th-century visionary and innovator in carriage manufacturing. His company grew to make bearings of all types, like specialty steel.
While electric motors perform highly complex tasks and are responsible for delivering many of the services we take for granted, it is really quite a simple concept. An electric motor converts electric energy into rotational energy. It is that basic.
Bearings don't just make machines possible here on Earth. Bearings are used in weather and other satellites, the Hubble telescope, and the Mars Space Rover, for example.
With positive displacement vacuum pumps, the cavity is expanded through the use of a mechanism that enables gases to flow into the chamber. Once the gases are in there, the cavity is sealed, the gas exhaust is vented, and the cycle starts all over again.
Ball bearing failure modes are most often the result of not rotating, which causes oscillating forces on the bearing to result in impact damage: called brinelling or false brinelling. Static maximum loads from non-rotating balls also cause component stress fracturing.
Different pump manufacturers specialize in different applications. For example, some are best for dealing with corrosive fluids, those at high temperatures, or large volumes. Your pump salesperson will be knowledgeable about the different brands and help you choose the right one for your needs.
