Understanding the Basics of Yagi Antennas

Yagi antennas are also known to the industry by another name, Yagi-Uda. Some would simply call it Yagi. Commonly used in communications, Yagis are a qualified directional antenna with frequencies above 10 MHz.

The antenna of this type are popular among Citizens Band and Amateur Radio operators and are utilized at satellite communications systems for their surface installations.

Components of a Yagi System

A Yagi system is usually comprised of 2 – 3 straight elements. Each of which is approximately ½ electrical wavelengths. There are 2 classifications for these antennas, they can be balanced or unbalanced. As for the Yagi type of antenna, they are usually considered as a balanced antenna. And yet you can feed them with coaxial cable together with another device referred to as a balun. This is the point where the driven element would be joining the feed line.

The Yagi driven element is comparable to the half-wave, center-fed dipole antenna. At approximately 0.2 to 0.5 wavelength on both sides of the parallel driven element, are straight wires or rods known as reflectors and directors. Reflectors, slightly shorter by ½ wavelength, are installed fronting the driven element.

It is quite typical for Yagis to come with one reflector but with plenty of directors. The antenna will propagate the electromagnetic field energy from the driven element direction toward the director(s). It is also very sensitive to incoming electromagnetic field energy from the exact, same direction.

High quality yagi antennas are not just going to have a response pattern and unidirectional radiation, they can also concentrate response and the radiation. If a Yagi system has more directors, the greater is this so-called forward gain. If more directors would be added to a Yagi, its natural response or tendency is to become even longer.

Some Yagis have plenty of directors, from 10 or even 12, which is on top of one reflector and the driven element. You seldom use long Yagis that are below 50 MHz. The underlying reason behind this is that these frequencies would render the structure to become physically unwieldy.

The Name Behind Yagi Antennas

Shintaru Uda, together with a colleague, Hidetsugu Yagi, conceptualized and invented the Yagi system of an antenna from a very long time ago, in 1926. In almost every part of the United States, there was a similar design and was called a log-periodic antenna.  

A Yagi system of antenna usually comes with 2-3 straight antenna elements. They are set to a length at least half the electrical wavelength they are intended to provide support. We qualify them as a balanced type, but this would depend if they are used with a balun, then they can be unbalanced, joining the antenna’s driven element.

One of the many benefits of the Yagi system of the antenna would include the ease of aiming the antenna and its range as opposed to many other directional designs.

A Yagi antenna is a qualified directional type, and for this reason, it will center the entirety of its signal to just a cardinal direction. This measure helps in making it possible to have increased gain over the omnidirectional models of other designs of the antenna.

How to Look for the Perfect 12 v Diesel Transfer Pump?

Before anything else, we need to give out a clear definition of what a 12 v diesel transfer pump is. When you have a good idea of what its intended purposes are, there is a good chance you will see if you need to have this piece of equipment for a project or not. 

As its name suggests, the main purpose of a diesel transfer pump is to transport water, or any kind of liquid for that matter, from one region to another. Such activities may include moving liquid, water as usual, from a dam to individual tanks. Or it could be out of your basement, or from an area in your construction site to another place.  

This also explains the reason why water transfer pumps became known to many of us as a dewatering pump. It significantly helps in eliminating water from a particular area. And it is useful most especially if that region is susceptible to flooding. By using diesel transfer pumps, the likelihood of flooding to occur can be alleviated. 

The market today is highly saturated with a wide array of water transfer pumps, thus, we have a lot to choose from whenever we have a need for one. But we must know what we are going to look for before we start shopping. If we do so, there is no way we can get the wrong kind of water transfer pump for your project.  

We are presenting below our no-fuss guide to finding the right 12 v Diesel Transfer Pump to buy! 

Select the size of the inlet/outlet

With regard to the application, water transfer pumps are available in a wide range of sizes. Like for instance, a lightweight pump is intended for use in the garden, around the home, and also for boating while the larger sized pump is ideal when you need to pump huge volumes of liquids to fill up dams or site flooding and anything similar.  

No matter what size you pick, you can expect that diesel transfer pumps will work in pretty much the same way. The liquid will get suctioned in via an inlet valve and eventually eject through the discharge valve. The manner in which how fast it gets the job done is what makes the difference.  

The speed of the liquid transfer would be depending upon the suction and discharge ports sizes, which is the inlet and the outlet. Normally their range is from 1 up to 4 inches. We reckon that a 4-inch port will be capable of moving water at least 4 times faster compared to a 1-inch port.  

Choose Flow Rate

It is typical for 12v diesel transfer pumps to have a low PSI capacity as opposed to a high-pressure fire water pump, yet powerful enough to carry large volumes of water. You can measure this up by the liter/minute flow rate. The amount of flow rate that you will require here will depend upon the task size at hand.

Like for instance, in a small domestic job, this would probably require 100 -200 liters for every minute of flow rate. A commercial task or a much larger property would be requiring 10 times that flow rate. 

We need to take into account the flow rate together with the pump’s “Maximum Head” capability. This pertains to the maximum distance or height which the pump can pump to. 

12 v diesel transfer pump tool

So this means to say that if you have a pump having 60 meters maximum head, you can anticipate a flow rate of zero at 60 meters. Therefore, it is safe to conclude that the flow rate will wane with the height or distance.  

Choose Your Engine Type

Consider the type of engine that you will need to have for your pump, should it be petrol, electrical or diesel-powered? The majority of the structural designs for electric water transfer pumps are intended for indoor smaller requirements. They cater to the various needs of a DIY user for their smaller domestic tasks. Most of the time they are less powerful and thus would be needing less maintenance as opposed to a diesel or petrol pump.  

Take in Account Their Design Features

What will you need a water transfer pump for? Water transfer pumps that are intended for commercial would usually come with specially designed features, primarily for use around a worksite. Here are some of the important things you will want to look for:

  • Anti-vibration dampening helps secure your pump in place and alleviates noisy rattling while the pump is in use.
  • Rollover casing gives protection to your water pump in case that it is knocked. 
  • Portability, allows you to move about your water transfer pump around your boat or garden.  
  • Low oil shutoff, allows for automatic stopping of the engine the moment that it is running short on oil — a mechanism to help it prevent damage on itself.

What Are the Benefits of Bunded Tanks?

For most companies that are involved in the production of the so-called industrial products, the storage and containment of petrochemical liquids, such as gas and oil which they use as fuel in their production of chemicals,  is more often than not a major concern.  

These business entities have a constant need for adequate amounts of these petrochemical materials to be used in their production facilities or sites. This means to say that they need to have no less than a secure and safe storage facility, after all, what they are handling are extremely toxic and hazardous substances. 

What Are the Benefits of Bunded Tanks?

Companies that are handling petrochemical substances in making their products can’t afford to have leakage or spills in their fuel storage facilities, because that happening can put every surrounding living things and the environment in general in harm’s way. Too often the price for such unfortunate events is extremely high.  

The growing trend right now when it comes to building storage facility is to veer away from underground tanks and silos. This has something to do with the need for a more efficient and safer storage facility for qualified hazardous materials. Right this very moment, there are increasing numbers of companies that are switching to the use of bunded tanks for their fuel storage options. 

One thing that makes bunded fuel tanks distinct from all the others is their double wall feature, designed to comply with the industry and government standards, they have proven safe and an efficient system for storing high-value liquids.  

Aside from concerns on safety and efficiency, there are a couple of other reasons why industrial firms have a special preference for bunded tanks over, say, for instance, the underground silo which is another form of a storage system. Building the latter is not just expensive, but comes with a manifold of requirements and of course you need to comply with them. 

On the other hand, self-bunded tanks are a more cost-effective form of storage system for high-value liquids. You can easily obtain if you have a dire need for one, aside from which they are immediately operational right after you acquire them.

Another distinct feature of bunded fuel tanks why industry experts have a special preference for them over other storage systems is because they offer great flexibility of use. If your facility does have a small tank of this type, you can have relocated to another facility or site instead. This signifies that you don’t really need to buy another tank, but if you already have acquired a bunded tank instead you can reuse it. 

Unlike underground tanks or silos, bunded fuel tanks are remarkably a lot easier to clean and maintain. Deep deposits of dirt, grime, and foreign debris, scratches or dents that are known to be the root cause of rusting or any other major damage to the tank can be readily seen in no time. 

However, companies are encouraged to take extra caution and care with regard to their choice of a fuel storage tank. It is very likely that not all manufacturers of these industrial items are using the one and the same technology in their production of it, which means to say that there would be some tank that is better than others in terms of durability, reliability, and price. 

Remember, when trying to shop or when trying to look for a storage tank for your high-value liquid, it does not always follow that the most expensive is tantamount to being the best. There are instances that cheaper tanks perform much better than exorbitant brands, and they last longer giving more value for your money.

Home Security Doors: Which One is Right for You?

 

The kind of surrounding we have today makes us paranoid- with all the crimes and inhumane activities happening here and there. This make us feel that we are actually not safe wherever we are. In fact, even with alarms, deadbolts, motion detector lights and securing monitoring systems, people with bad intentions like burglars can get still get it.

Such thing leads people to home security doors. However, you may find yourself a bit confused as there are so many types to choose from. Here is a guide on how to choose the right door for your specific need.

Why Opt for Security Doors?

The purpose why you need security doors and windows is definitely not for the aesthetics of your home. Instead, these are designed to provide safety and protection. Thus, if you want a glass door for instance, you need to understand that a glass door will never be the best material for your security door.

The best choice would be a wooden wood as you can select a door that is made out of a tough and strong wood like an oak. For other softwood doors, although they may look pretty, they may not be able to withstand attacks.

Are Security Doors for Everyone?

Admittingly, these types of doors may seem expensive for some. Instead, to make things work they will protect themselves by installing deadbolts to their doors. Although this is a good idea in keeping intruders out, in case of emergency and people need to get in this might not be a help. Especially if you don’t have the key, you won’t be able to be of assistance.

Being able to choose the right security door is of utmost importance, yet it can be a challenge. For example, there is a kind of door that has a complicated lock system and might only be opened with a key. Although this can provide barricade for intruders who want to get in, burglars can still break into doors with keyless systems.

Machinery Repair Basics for Beginners

Machinery repair will be warranted by your suite of industrial machine at one point, and there is no going around this fact. Even the most well-maintained piece of equipment will reach the end of its lifespan, which can trigger issues that can derail its operability. Fortunately, ensuring quality repairs is very possible. If it will be your first time to deal with them, appreciating this fact is a must: commissioning successful repairs begins with understanding the value that they can provide to the functionality of your facility. In addition, here are other important pointers to remember.

 

Always check your manual

Your manufacturer’s manual outlines all the information that you will need, when it comes to the operation of the machine. If you’re calibrating the equipment for the first time, your manual will guide you through the initial setup. And if you’re commissioning repairs, your manual will apprise you of certain specifics that need to be factored into the process. Doing this will also preserve the warranty of the equipment so before you touch your machine, make sure that you know what to do. If you’re commissioning a third-party repair company for the repair, this is even more critical.

 

Get your team involved

Also, don’t discount the amazing help that your team can provide for industrial machinery maintenance and repairs. Anything that involves the suite of machinery that you all work with merits the attention of the entire team, and repairs are no exception. Your team should approach them as a collective effort because it will:

  • Ease the sharing of critical information in your facility
  • Help define tasks and roles more clearly
  • Inculcate a culture of proactive efforts; and
  • Provide a solid foundation for comprehensive maintenance

Make sure that your staff is properly apprised of their specific tasks during repairs, and log everything.  Documentation should be solid and dependable before, during, and after the repair.

 

Design a good preventive maintenance programme

Speaking of maintenance, your items like air compressor machinery repairs should inform the inclusions in your preventive maintenance programme. Preventive maintenance is essential to keeping costs down while ensuring maximum potential functionality in your facility, and what you glean off the repairs will be a big part in that. If you notice patterns, for instance, they should be assessed and then incorporated into your maintenance programme. They may signify that there are operational conditions that you will need to better manage to reduce the occurrence of damage.
