Simply put, a shell and tube heat exchanger is used to cool fluids on a large scale, such as in an oil refinery. The device consists of a pressure shell that contains tubes. Fluid is directed around the tubes using baffles.
To function, two fluids of different temperatures are fed into the exchanger. One flows through the tubes and the other flows outside the pressure shell. As the second fluid passes over the tubes the heat of the two liquids are exchanged. Tubes come in one-pass and two-pass forms.
When it rains it pours! While readying the guest bathroom for an overnight visitor, the faucet handle came right off. I’m pretty handy with a set of tools, so I went about disassembling the handle and unscrewing the back plate to take a look at the cartridge. Unfortunately, everything in our apartment is so old that the cartridge was lodged firmly in place. I threw my back out trying to dislodge the broken cartridge.
Finally, I gave up and called a plumber. Since it was a simple fix (and I had done most of the work already) they were able to get me fixed up in no time. I asked lots of questions – hey I still had to pay the whole fee! – about future repairs. I learned a lot and even picked up a tip on removing the seat valve from a sink faucet.
A CNC lathe – Computer Numerical Controlled lathe – is designed to use a modern carbide tooling process. Computer menu style interface is used to control the machine. Operators of a CNC lathe need a high level of knowledge regarding the machine in order to set and operate the CNC.
Design of a CNC lathe can vary depending on the manufacturer’s needs. That being said, all CNC lathes have common elements. For example, the turret always holds and indexes the tool holders. The spindle will always hold the workpiece and slides always move the turret.
When I was first approached by an employee about purchasing a new COP tank, I wasn’t sure what she meant. I did a bit of research and found out that COP stands for Clean-Out-of-Place. Frequently, COP immersion washers are used by pharmaceutical and biotech processing facilities.
A COP immersion tank is really a washer with a turbulent circulation system. Techs place dirty parts into the tank and the currents thoroughly wash the interior and exterior of the parts. COP tanks are especially useful for cleaning small parts where human hands might not fit for a thorough scrubbing.
A check valve may be installed in a house water line in order to regulate water entering and exiting. Though a check valve in a water line requires little external interference, it is important to test the check valve every now and then to ensure the correct water pressure is entering the home. To test the check valve, begin by opening the high-side and low-side bypass valves. Then attach the high-side hose on the test kit to the fitting, which is usually to the left side of the check valve.
The low-side of the hose from the test kit should be attached to the testcock to the right of check valve. Turn off the first shut-off valve (connected to the water line) and then slowly open the testcocks to which the hoses are attached. Open the high-side bleed valve and then close the low-side bleed valve. Read the PSI on the test kit to see if the water pressure is where it needs to be.
Similar to a car, a Baldor motor should be checked every three months or every 500 hours, whichever comes first. If you notice any problems, then check the Baldor website. They’ve compiled a handy chart of common problems and their solutions. For example, a strange noise may be caused by material trapped in the air gap or ventilation opening.
Baldor motors are particularly vulnerable to high ambient temperatures, as well as dirty working conditions. Be sure to check the maximum operating temperature and duty cycle of each Baldor motor. This information is usually found on the motor’s name plate.
Butterfly valves are typically used to isolate or regulate the flow of water. There are three main types of butterfly valves: concentric, double eccentric, and triple eccentric. The concentric butterfly valve usually has a rubber seat with a metal disc.
A double eccentric, or high performance butterfly valve, can have a variety of materials for the seat and disc. A triple eccentric butterfly valve, also known as triple offset butterfly valve, can be made with either a laminated or solid metal seat design. The triple offset valve design are used solely in applications that require bi-directional shut-off, such as in oil and gas, chemical factories, and ship building.
When you are looking to redesign your shower there are different types of enclosures that you can choose from. Conventional enclosures are the most commonly used. There are a variety of different styles that are available for you to choose from. They come in different colors, textures, and shapes.
A more popular choices are Stainless Steel or Copper enclosure. The appearance as well as durability is why these types of enclosures are more eye appealing. Stainless steel are non corrosive, resistant to stains and finger prints. These type of enclosures will stand the test of time.
There are different types of check valves. The one type that you will want to make sure that it is working in excellent condition is a backwater valve. This type of valve is used for sanitary drainage systems. If you have ever had a sewage backup then you know exactly how important it is to make sure that this type of valve is functioning properly.
A backwater check valve protects lower located rooms against flooding caused by return flow of sewage waters. Backwater valve prevents rodents and rats to enter the sanitary and rainwater drainage system as well as the building interiors. Preventing a sewage blockage is something that is important to prevent. The smell is un godly as well as the clean up.
Although most of us know Suzuki for their work in the auto industry, they actually have an entire aquatic line called . Rather than being a traditional “boat company,” Suzuki Marine is a motor company. This means they can translate the technology they have already developed in their numerous vehicles to power items such as motorcycles, ATVs, and boats.
The engines themselves are designed to be lightweight with the maximum amount of output. They are also distinguished from similar companies for being 4-stroke cross valve engines that are surprisingly quiet and fuel efficient. And that is becoming increasingly important to boaters as the cost of boat fuel far exceeds the cost of auto fuel, which itself is already at an all-time high.
