Pneumatics is a branch of engineering that makes use of gas or pressurized air. Pneumatic systems such as cylinders, air compressors or actuators are all used extensively in the industry. Hydraulic accessories are also offered and include both motorized and electric butterfly valves.

HOW TO USE A MOTORIZED BALL VALVE TO CONTROL AN IRRIGATION SYSTEM

If you have an elaborate irrigation system for a vegetable garden, you may want to install a motorized ball valve or several of them for a variety of reasons.  The benefits include better convenience, faster control and safer operation compared to more basic set-ups.  For example, a motorized ball valve can be used as an emergency shut-off, if it is installed at the point where the water source connects to the irrigation system.  For many users, this is the place where the garden hose connects to the PVC pipe that feeds into the drip lines.

Furthermore, a motorized ball valve is useful as a control mechanism to shut off sections of the garden that may not need water or to prioritize which plants get watered during a drought.  What’s more, a motorized ball valve can help quickly relieve pressure in the irrigation system; excess pressure can cause irrigation pipes to burst.

The ultimate benefit of using a motorized ball valve over the basic manual control valve is convenience.  The motorized version allows you to hook up an external on/off switch that you can place somewhere that is easy to reach — near the electrical outlet, in your garage, etc — so that you can control your system remotely.

For this example, Deelat’s motorized electric ball valves can be installed to control the irrigation system between a garden hose (connected to the house’s spigot) and the irrigation system.  Among the models suited for this purpose are motorized electric ball valves that consist of a 24V AC on/off actuator and a 2-way brass or stainless steel valve.

valve 3  SKU# D1156046

First you will have to select a motorized electric ball valve that matches the size of the PVC pipe you are using for your irrigation system.  There are a wide variety of couplers and adapters to connect brass or stainless steel to PVC, and you may also need an adapter to connect your garden hose to the valve if there is a size difference.

The actuator has 3 wires:

  1. Blue Wire = Negative/Neutral

The blue wire is continuously connected to the 24V transformer’s neutral connection.

  1. Brown Wire = Positive

The brown wire is continuously connected to the 24V transformer’s line connection.

  1. Black Wire = Controlling wire which is also Positive

The black wire connects to the 24V transformer’s line connection through a switched connection.

The valve opens when the switched connection is completed between the black wire and the 24V transformer’s line connection.  When this switched connection in broken, the valve closes.

Follow these steps to complete the set-up:

  1. Install the actuator on the valve.
  2. Attach the actuator’s blue wire directly to the neutral connection on the transformer.
  3. Attach the actuator’s brown wire directly to the line connection on the transformer.
  4. Attach the black wire directly to the light switch (either connection is fine).
  5. An additional wire is needed to connect the other connection on the light switch to the line connection on the transformer.

If the connections are done properly, you can test the unit by plugging the 24V transformer into an outlet and flipping the light switch, which should close the valve.  Flip the switch to the opposite side and the valve should open again.

Applications for using Pneumatic Air Riveters

Pneumatic Air Riveters are a tool that can be used for a variety of applications, all of which are very satisfying and efficient to use. A pneumatic air rivet gun uses a hydraulic system and is powered via air pressure fed into the bottom of the tool. It then fires a rivet into a pre-drilled hole which creates a secure bond between two items. It can be used in a variety of industries, including construction, metal fabrication, automotive, aeronautics, and woodworking.

Below are some of the main applications for using Pneumatic Air Riveters:

 

For Decorative Effect – There’s something primal and powerful about using rivets in metal which means they don’t always have to be used for practical purposes. Riveted metal has been used for decorative purposes for years and can be used as part of a frame for a mirror or picture. It can also be used to build a lamp stand or a metal desk or chair. Of course, some of this will involve riveting for practical as well as decorative effect, but all are still aesthetic decisions based on your decor. Check out Pinterest for some examples of the kind of design applications you can use your riveter for. Seasonal decorations (ie, Halloween, Christmas etc) can also be attached to walls with rivets to make sure they stay in place.

Woodworking – Riveting is best known as a way of bonding metal but it’s also frequently used in woodworking too. Rivets actually work better than the traditional nails and screws when it comes to securing pieces of wood together in the assembly of furniture, shelving, etc. Of course, it can also be used for attaching the hinges, runners, handles and knobs, and would probably be even more commonly used if screws weren’t seen as the easier option for flat-pack self-assembly.

General DIY and Home Building – Your rivet gun has so many applications around the house, whether you’re starting from scratch or doing some maintenance. Guttering needs rivets to be held in place and to be attached together, while anything made out of fiberglass is best constructed with a riveter too. Other household fixtures that can – and often need to – use rivets include doors, windows and blinds, so it really is a tool that will constantly come in handy if you regularly do work around the home.

Belt Grinder: Types, Applications and How to Buy

A variety of grinders, which are machines that are used to smooth surfaces, remove material and deburr metals, are used in metal working. A belt grinder is one common type, and they are used for a wide variety of applications. For example, belt grinders are commonly used in knife making.

The biggest difference between belt grinders and other types of grinding machines: Belt grinders use a fast-moving coarse belt, similar to sand paper, to contour metals. Other types of grinding machines, though, typical use a metal blade or grinding bit to remove material.

Belt Grinders vs. Belt Sanders

There’s some common confusion about the difference between these two devices. They both work in a similar manner. The motor powers a fast-moving stationary belt, which the operator then engages the materials to make them smooth and add contour. But that’s where the similarities stop.

Of the differences, belt grinders are typically designed to be used with metal workpieces, whereas belt sanders are used primarily with wood. Additionally, the differences include:

  • Belt grinders tend to have faster belt speeds, from 70 to 135 feet per second. This is needed when working with metals.
  • Their motors have more horsepower.
  • And they’re designed to be used with flat or rubber platens.

Due to the grinders greater power output and faster belt speeds, these machines tend to have the ability to remove material from the workpiece and smooth metals. Using a belt sander with metals will result in damage to the machine and/or undesirable results.

Belt Grinder Applications

In metal working, belt grinders are used for a variety of tasks. There are three main tasks though:

  • Deburring: Metal burrs can form on the surface of workpieces. Belt grinders remove these burrs. Additionally, they are used for edge breaking and rounding metal materials.
  • Surface Finishing: Like belt sanders, grinders are used for sanding, smoothing or roughing the surface of a material. This can also include removal of tiny burrs, polishing and cleaning the material, removing mill marks and edges.
  • Removing Material: Belt grinders are commonly used to sand metals and remove material. For example, belt grinders are commonly used in knife making to shape metal blades. Typically, belt grinders are designed to remove tiny bits of material with each pass.

Considerations When Buying Belt Grinders

It’s important to match the belt grinder to the work that you will be doing. And to accomplish this, there are many considerations you will need to make. The two biggest include:

  • Belt size: Belts for grinders average from about 1.5 to 6 inches in width. Wider belts are used for larger work pieces, while narrower belts allow for more precision. If you want to use a range of belt sizes, choose a grinder that can accommodate more than one width.
  • Belt Speed: Typically, faster belt speeds are required for removing material more quickly. Slower speeds are best-suited for smoothing and deburring metals. Choose a belt grinder that has a selectable range of belt speeds.

Air Rivet Guns: Common Applications, Types and Features

Solid rivets are a widely used fastener in industrial applications for strongly binding together an assembly. They’re typically used in aircraft and automotive manufacturing, as they are more durable and create a more sturdy binding than a screw and nut. The process of “setting” a solid rivet requires a specialized tool called an air rivet gun.

Air rivet guns work by driving the rivet into place. The process begins by inserting the rivet into a pre-drilled hole, with the protruding end, called the shank, backed up by a “bucking bar.” Then, as the rivet head is driven with the rivet gun, the back end is deformed, creating a “shophead.” In the process, the rivet swells in the hole, creating an extremely tight bond.

Air Rivet Gun

There are numerous types of hydraulic and air-powered rivet guns, and they all have different capabilities. Some are slow-hitting, striking the rivet head with 2,500 hits-per-minute, or fast-moving, which is up to 5,000 hits-per-minute. Slow-hitting air rivet guns, which are sometimes called pneumonic hammers, are one of the most common types used in industry. Additionally, these guns are also determined by their size, shape and their ability to drive certain sizes of rivets. For example, a 2X rivet gun, which is on the lower end of the spectrum, can reliably drive 1/8” and 3/32” rivets, but it is not powerful enough to drive 1/4″ rivets.

Factors to Consider When Selecting a Rivet Gun

Air rivet guns provide controlled hitting of the rivet head. They differ from other types of air-powered devices like an air hammer or air chisel, which strike too hard and too fast to be used in riveting. These types of tools can quickly damage or dent the sheet metal around the rivet.

Choosing the correct type of air rivet gun can be a complicated process. You should consider:

  • Hitting speed: Hitting speed is the rate at which the rivet gun strikes the head of the rivet. Typically slow-hitting rivet guns – in the range of about 2,000 hits-per-minute – provide a greater degree of control, compared to fast-hitting guns. In addition, the fast-hitting rivet guns create more force, but aren’t typically necessary for smaller sizes of rivets.
  • Size and Capacity: Capacity is one of the most important factors to consider. In general, this refers to the rivet gun’s ability to drive rivets of a certain diameter. For example, quarter-inch rivets or M6 rivets require a gun with a greater capacity to be properly set. This is generally measured in pulling power or RPM. The larger the rivet’s diameter, the greater the capacity of the gun will need to be.
  • Stroke Length: This is the distance that the rivet gun’s driving head takes each time it hits the rivet. Some guns are adjustable, and there are also extension pieces available to increase the stroke length. Stroke length is important for applications in confined spaces, like a rivet that is attached within a protected hole.
  • Rivet Set Sizes: You must match your rivet gun to the size of the rivet that you will be setting. There are two different types of measurements – Imperial and Metric. For example, an M6 air rivet gun can be used to drive M6 rivets. (This is the metric diameter of the rivet head, which is 6mm.) In general, many rivet guns are adjustable, allowing the operator to interchange heads to fit the type of rivet. To be safe, a rivet gun set with a range of sizes is a solid investment.
