Function of Sound Attenuators

The basic function of a sound attenuator is to reduce the noise created by the fans in heating and ventilation systems.  They are designed to absorb the noise and create a more peaceful and quiet environment. All HVAC systems tend to make a great deal of noise which can create noise pollution as well as hinder productivity during the day, after installing an attenuator, the noise is considerably reduced.

Most sound attenuators are usually fitted in the supply or exhaust ducts. The size of an attenuator depends on the kind of air conditioning system in use. These are available in 4 inch, 6 inch, 8 inch, 2 inch and 16 inch diameters. Attenuators are designed from a variety of materials.

Customised Sound Attenuators for Boating

Customized sound attenuators are all the rage these days. These are designed exactly according to the demand of the system. They could be circular or rectangular in design, however rectangular attenuators are given more preference.

There are certain things which you should keep in mind before purchasing a customized attenuator. These include the following

  • The design of the attenuator should be such that it supports as minimum pressure drop as possible.
  • The attenuators must guarantee an optimal performance. It should help reduce the noise to a considerable extent so that the working environment is as peaceful as possible.
  • The attenuator must be designed by a well reputed company.

When buying a sound attenuator you have got to keep certain things in mind like your budget and your actual requirement. If yours is a small se up with a few people working in the office, any sound attenuator would do. However for larger corporations which have huge HVAC systems, it’s necessary to select the right sound attenuator.

Things like the total width and circumference of the attenuator should also be kept in mind. The first step in doing so would be to completely analyze your system and then make a decision based on that analysis.

You need to ensure information about all the following

  • Determine the insertion loss ranging from a frequency of sixty three Hz to eight thousand Hz
  • The complete air flow in the system
  • The amount of pressure drop
  • The size of the duct and exhaust fans
  • The total length of the silencer which would be required for your specific system
  • Once you have all the above information, selecting the right sound attenuator is pretty eay. These dimensions and sizes help you find the perfect noise control solution for your HVAC systems.

Some other factors to consider when buying sound attenuators is to see whether they have a space saving design. Plus things like being environment friendly is also pretty important. The insulation should be present on the attenuators as ell to improve its productivity.  The attenuators must be designed as such that these are easy to install as well.

Are you looking for goo quality sound attenuators? Look no further, make sure you check out the variety available at Aletek. The designs are easily compatible with all kinds of HVAC systems and are great value for money as well.

What are Drum Pumps used for?

Liquid management is not an easy task in various industrial plants especially when the liquid is above 50 pounds and this is a real crisis for barrels and even drums. You may say that barrels are large and strong enough to hold huge amounts of fluids; however, when it comes to extracting such fluids from these barrels it is really difficult. The only solution to this great problem is using a drum pump.

What really is a drum pump? A drum pump is a type of instrument that you place on the upper opening that is usually used to transfer and empty the liquid in the drum or barrel. You don’t have to pivot the drum so as to remove that liquid. Basically, there are two types of drum pumps according to their materials, models and the tube lengths. The following information has been supplied by: Oil Drum Pump , Drum Pump & Oil Pump suppliers.

How really does a Drum Pump Work?

A drum pump is fitted on the upper opening of the barrel and its narrow pipe goes down into the liquid. The pump has a vertical shaft which works through direct current by the help a tiny motor which is attached to it. The motor functions when the switch is turned on.

When you have placed your pump properly, switch on the pumping mechanism which originates from the lower point of the pipe which works by sucking the content. Usually, a relatively small centrifugal pump rotor is located at the base of the pipe.

Usually, there are diverse types of fluids that mostly require processing, transportation, handling and even transferring. This should tell you that drum pump is not only used in industries that use water. Oils are heavier than water and therefore, it becomes very hard for them to be emptied. That’s why most industries that are using non-hydro based fluids opt for drum pump.

Some of the industries that use drum pumps include chemical plants, processing plants, manufacturing plants, food processing and also other cleaning jobs.

Types of Drum Pumps

Different types of drum pumps are determined by the way they are used, their types and of course their models. So how to select a drum pump? The two types of drum pumps include:

  1. Hand – operated drum pumps

As their name indicates, their functioning is usually enabled by a hand rather the motor. They are common in places where there is the unavailability of power. They are available in various subtypes like steel, aluminum, plastic, sulfide and also PVC. They also come up in different shapes and lengths which offer you with an easy, spark-free and leak-free pumping mechanism.

  1. Electric operated drum pumps

They usually pump by the use of electric power and mostly used in areas where there is transfer/emptying of high volumes of liquids in the barrels and tanks. They come in different models that use electricity and also batteries and they are built to handle various voltages.

It works best when it is working with thick and heavy liquids like crude oil and bitumen. They come in sizes, shapes and even lengths.

Now that you have known the types of the drum pump, what should you look up to when selecting a drum pump?

Factors to Consider when Selecting a Drum Pump

Some of them include:

  • The purpose or the use of the pump- this will enable you to buy the right motor, pump series etc.
  • Check the compatibility
  • Make sure the tube you are using is resistant to chemical reaction
  • Have an explosion proof in case your liquid is flammable
  • Make sure you purchase accessories of your drum pump.

In conclusion, drum pump is one of the practical way and option you can use to empty your barrel and also to fill it. And of course, you will enjoy its portability nature. Stop tipping that heavy barrel and acquire your drum pump today.
