Engineering is a career with a wide variety of specializations. Everything around you is built or designed by someone with the help of a professional. One of these professionals is a defence engineer, specifically trained to build, design, or simply … Continue reading What Is Defence Engineering and How Is It Different?
A check which having the word void is known as voided check. The word void indicates that the check will not be used for the purpose of payment. What is a voided check? A voided check contains the check numbers, … Continue reading How To Void A Check: The Simple Process For Checking
Vibration Induced Fatigue; Vibration Induced Fatigue is a form of fracture due to fatigue, mechanical (of mechanical Fatigue) due to Dynamic load caused by vibration ( with Vibration) had done so at the risk of Vibration Induced Fatigue is a point there. High stress and severe shaking points. This type of damage is usually found at the small branch connections of Pressure Vessel and Piping, which are naturally high-stress points because they are discontinuous (see Stress Analysis) and are the receiving points. Vibrating force Thus, if the Support inadequate and the Small Branch Connection with Vibration ( for example, near … Continue reading What is Vibration induce cracking
Oxygen Scavenger (Corrosion Inhibitor); Oxygen Scavenger is a chemical used to inhibit Corrosion one that removes Oxygen in reaction Corrosion by being put into the water Boiler feed water to get rid of Oxygen , or from the rest of the Deaerator before release to manufacturing Steam.

The most important factor in ensuring a pump system offers a long service life is to get the installation right. No amount of good engineering, proper pump selection, or correct application of pumping technology can overcome the challenges a poor installation can throw at a pump system. So it’s critical that we all know the bare minimum requirements to ensure a good installation. Step 1: Read the Manufacturer’s Installation Instructions Virtually all pump manufacturer’s offer Operation and Maintenance Manuals (O&M’s). In addition to information on proper pump operation and maintenance these manuals usually also provide information on how to install … Continue reading Pump installation guides
It’s important to size an electric motor properly. Doing so will produce a pumping unit that is more efficient and provides a longer service life. Failing to size the motor correctly will result in a pumping unit that demands more power than it should or one that produces repeated electric faults and may suffer from premature motor failure. A Basic Introduction to Pump Motors Electric motors are generally sized at predetermined intervals. What this means is that in most cases you will need to round up to the next available motor size when determining how large a motor to couple … Continue reading Pump motor selection
Years ago, making a pump selection meant sitting down with large printed catalogs and flipping through them until you reached a pump curve that fit a project’s hydraulic requirements. Today this process is made much easier through the use of electronic pump curve catalogs. One of the most well-known developers of electronic pump catalogs is Engineered Software and their pump selection software pump-flo. Another popular option for pump selection software is Intelliquip. All of the curves in this article were generated by Pump-Flo’s web-based pump selection software. What is a Pump Curve? A pump curve is a graphical representation of the performance … Continue reading Pump Curve Understanding
In a previous article, we discussed some common impeller and casing designs. This article will consider what happens when you put the two together. End-Suction Pumps End-Suction Pump from Wikimedia Commons The most common centrifugal pump design is the end-suction pump. This type of pump combines a volute casing with a variety of impeller designs. Most typically, a radial flow impeller would be used, but in certain specialty applications, Francis-vane or mixed-flow impellers may be used. End-suction pumps are used in a large range of applications. Standard end-suction pumps are commonly used in fire suppression, plumbing, HVAC, and municipal water … Continue reading Centrifugal Pump Designs
There are a few components that virtually every centrifugal pump has in common. These components include: An impeller A volute or diffuser style casing A shaft Shaft sleeves Bearings A sealing arrangement These parts can be subdivided into the wet end and … Continue reading Centrifugal Pump Structure
