!: DIY USB-Controlled Servo Squirter Water Pump

In this video, we'll show you a simple project where we connect a hobby R/C servo to a small water pump, and control both from the USB NerdKit. Using input from the connected computer, you can aim, and fire a stream of water. The video also introduces topics like Pulse Width Modulation (PWM), including how hobby servos share a common protocol (1.0 to 2.0ms pulses), and how to use the ATmega168 to generate these pulses.

Different Types of Well Pumps and Their Uses

!: Different Types of Well Pumps and Their Uses

Wells and the pumps that bring the water to the surface are fascinating and high-output investments that do a great deal for your energy consumption, your utility bills, and your health. However because of the incredible diversity of the terrains and water tables and types we face, there are many differing strategies on how to bring the water from the ground to your home.

If you live in a region with a low water table, meaning that you are not too close to a body of water or underground source and will have to dig quite far to reach paywater! But if you live in a reasonably high water table area, you may find that getting the hole dug is half the battle, and the other half is the proper use and implementation of your water depending on your unique requirements.

Shallow well pumping is often done by what's called a jet pump. A jet pump is similar to a long straw which uses suction to bring water up from these relatively short heights. Jet pumps generally taper off in effectiveness after 25 feet, at which point you would have to dig a deeper well and initiate a more effective pumping system to carry the water up a greater height.

The next step for deep wells is what is called a double jet pump. A double jet pump is not all that dissimilar from a jet pump except that it uses two points of suction to create two pressurized vacuums to lift the water a greater height, usually at a faster velocity. The second jet would usually be placed at the bottom of the water in order to create two separate vacuums to process the water.

Any pump in the water itself is called a submersible pump, and it works a little harder by pushing water up from the bottom, but it means less force than a pump which would lift water up from the bottom. Like anyone moving a piano knows, it's always easiest to lift from the bottom instead of dangling over it hoping to support the weight.

Every well and pump has a situation and place, but it's best to let a well and pump professional survey your property and make recommendations as to how best to pump your water out from the ground. Knowing how and where to pump makes the whole situation easier, cheaper, and more energy efficient.

Submersible Pumps

!: Submersible Pumps

A submersible pump is one that has a sealed motor, fitted in a pump body. The total assembly is immersed in the fluid that needs to be pumped. The main advantage of this type of pump is that it can offer a considerable amount of lifting power, as it does not rely on external air pressure.

A submersible pump has a system of mechanical seals that is used to prevent the fluid being pumped from entering the motor, resulting in a short circuit. A pump can either be attached to a pipe or a flexible hose.

Some of the types of submersible pumps are bladder pumps, bilge and ballast pumps, borehole pumps, booster pumps, and centrifugal pumps. Other examples are condensate pumps, dewatering pumps, fountain pumps, grinder pumps, micro pumps, sampling pumps, trash pumps, utility pumps, and well pumps. Some submersible pumps are manufactured for particular applications. These pumps are water submersible pumps, sewage submersible pumps, 12-volt submersible pumps, sand submersible pumps, irrigation submersible pumps, and solar submersible pumps. Solar submersible pumps have many uses and are suitable for slow and steady water transfer into a holding tank.

Submersible pumps are found in many appliances. Single stage pumps are utilized for drainage, sewage pumping, common industrial pumping, and slurry pumping. Multiple stage submersible pumps are normally used for water abstraction. These pumps can also be found in oil wells. Moreover, submersible pumps can be positioned directly in a pond and require comparatively little installation. These pumps are also relatively silent.

The four main specifications that should be considered while choosing a submersible pump are maximum expulsion flow, maximum discharge pressure, horsepower, and discharge size.

Earlier, the main drawback of submersible pumps was that its pump seal could rupture and release oil coolant into the water. However, newer pumps are magnet-driven, and no longer require a coolant. These magnet-driven pumps are more expensive, but they consume less electricity.
