Nowadays if you approach any general contractor or developer form Hollywood Park Chicago to West Ridge Chicago, about a reliable Architectural Engineering in Chicago, the most popular answer is reach out to NY Engineers. What is very well known is that NY-Engineers.Com is probably your top choice for anyone looking for a fire sprinkler engineer in Des Plaines. At NY Engineers our staff has many years of experience designing fire protection and sprinkler systems from New City to North Bay Shore, New York. Today, from our Chicago office we are helping contractor and developers in Des Plaines design the fire protection and sprinkler systems they need.

The possibility of a building burnt down because of fire can be a sight that no one wants to enjoy. That is the reason why fire protection engineers are hired before a building or apartment is built. In case you are wondering who needs fire protection engineer, then a first name that you should know may be the architect of your building. Just like an architect is very important to make certain that the design of the property is perfect and safe from all ends; a fire protection engineer ensures that your building remains safe and secure from possible chances of fire.

Seeing fast reaction from the firefighting professionals is okay but won’t it be great if the fire never took place? You have to think of “what if” as an alternative to experiencing the horrifying scene of your building being on fire. Fire protection engineers check out the design of the property first then plan the escape routes to be used during a fire. Additionally, they are responsible for putting in many fire protection components inside and out of the structure. Water hosepipes linked to the main water supply, and checking the usefulness of the fire extinguishers are some of the duties that the fire protection engineer performs while they are hired.

Distinction Between Des Plaines Fire Protection Engineers vs Tech

The Society of Fire Protection Engineers carries a specific definition of Fire Protection Engineers vs Tech. The two positions require a solid education in fire technology and know-how being a firefighter in many instances.

The engineers use principles to make use of methods and systems setups in a variety of structures that really help protect folks and animals from injury during fires. Engineers analyze where the biggest fire threats lie and where to put protection such as sprinklers. They make certain that the utilization of residences as well as any materials in them are meant to keep dangers to a minimum.

Engineers will likely manage the connection and maintenance of smoke detectors, alarms systems, and definately will carry out investigations of fires after it happens. This can help them stop such things from occurring later on.

This type of rank employs scientific principles to help you increase the safety of folks in homes and offices. A fire technician functions is to conduct the testing and maintenance of the systems that were arranged and presented with the engineers.

They should also possess the highest education and firefighting training to operate within the field. They may also work to aid put in fire alarms and sprinkler systems but they usually do not create the design of the systems just like the engineers do. There is a great possibility you would like additional info on fire sprinkler system engineering services in Des Plaines by NY Engineers we invite you to take a look at our Chicago CAD to Revit Modeling blog.

Using Proper MEP Engineering to Protect Water Booster Pumps from Cavitation

MEP Engineering Books

Booster pumps play a very important role in ensuring a continuous water supply. In the absence of a booster system, most buildings only get a reliable water supply for the first five floors. For this same reason, keeping booster pumps under optimal operating conditions is a very important part of MEP engineering, and one of the main causes of impeller failure is an hydraulic phenomenon called cavitation. This article will provide an overview of cavitation and how it can be prevented.

What is Cavitation?

Everyone knows that water can be boiled with heat, turning it into vapor. However, low pressure can also vaporize water, and this can happen inside a pump if water is not supplied with enough pressure at the intake. When the pressure of a fluid drops below a critical value called the vapor pressure, small bubbles form in the flow, and these bubbles collapse violently once pressure increases again – the phenomenon is called cavitation, because the bubbles are cavities in the fluid.

You may be wondering how a pump reduces fluid pressure, when its actual purpose is to increase it. The answer can be explained with Bernoulli’s principle, which states that a fluid loses pressure as it speeds up or as it rises to a higher elevation. Water speeds up at the pump suction, and its pressure drops momentarily before being increased.

One bubble forming and collapsing does not cause major issues, but consider that thousands are continuously forming and imploding when a pump has severe cavitation issues. The combined shockwaves of all these bubbles gradually erode the pump impeller. When removed, the impeller blades will seem to have corroded, even though cavitation does not involve any chemical processes.

Other than impeller erosion, cavitation has many negative consequences in water booster pumps and other similar systems:

  • Vibration: The ongoing formation and collapse of bubbles not only wears down the impeller. The resulting shockwaves also shake the impeller, inducing vibrations in the entire shaft, with the potential to damage other system components. Seals and bearings are especially vulnerable to vibration.
  • Noise: Cavitation is very noisy due to the imploding bubbles. For a person close to the affected pump, it may sound like there are small rocks or marbles are being pumped along with water.
  • Decreased performance: Cavitation represents wasted energy, and this can be reflected as a reduction in flow or discharge pressure. A sudden drop in pump performance without an evident reason may indicate cavitation.

Preventing Cavitation With Adequate MEP Engineering

The technical specifications for pump manufacturers typically include a value called the Net Positive Suction Head (NPSH) required, which can be defined as simple terms as the minimum water head required at the pump suction for normal operation. If the actual head is above the NPSH required, no cavitation occurs.

In theory, cavitation can be prevented by increasing the suction pressure or by reducing the speed of water as it flows through the pump impeller. In practice, there are many ways to accomplish this effect.

  • Reduce pump speed: Cavitation is less likely at lower RPM values, so a booster pump can be slowed down with a variable frequency drive (VFD), as long as the system continues to meet the pressure and flow requirements in the local plumbing code.
  • Install the pump at a lower level: Static water pressure is higher at the lower levels of a building, so installing it at the lowest elevation possible reduces the chance of cavitation.
  • Reduce temperature: The critical pressure at which cavitation occurs increases as fluid temperature increases. If water must be pumped and heated, make sure the pump is installed upstream from the water heater.
  • Selecting the right pump: Many cavitation issues can be attributed to poor pump selection, and the issue disappears when a pump that matches the application is used.

The best solution for cavitation is not allowing it to occur in the first place, and this can be accomplished by working with qualified MEP engineering professionals from the start of a project. Modifying actual projects is far more expensive and time consuming than editing construction plans and specifications. A high-level professional design will not only prevent cavitation, but also optimal equipment capacity, energy efficiency and local code compliance.
