Pressure Washing Driveways Without Chemicals

!±8± Pressure Washing Driveways Without Chemicals

Pressure washing driveways without using any chemicals might seem almost impossible to you. Many people argue that using chemicals is the only solution to remove the tough stubborn stains that easily seep through the driveway surface whether it is concrete, asphalt, gravel or any other material.

Using a pressure washer has become a very popular option for cleaning the exteriors and interiors of a house, office or any building. Pressure cleaners that make use of high pressure are popularly used by professional cleaning companies. These machines do not use chemicals to remove tough stains while driveway cleaning. Yes, you read it right. High pressure washers propel out water at extremely high speed. This force is enough to loosen even the most stubborn stains off the driveway. The same amount of water is used to wash the surface as well. So a pressure washer simultaneously loosens up the dirt and also removes it off from the surface at the same time. It also makes use of very less water when compared to a garden hose which uses up large quantities of water to rinse and clean the entire driveway.

It is almost impossible to use a garden hose to clean oil spills, grease, etc. without using a chemical or detergent. If you are looking to cut down on using chemicals and if you are environment conscious, then pressure washing might be just the right option for driveway cleaning

You can either hire a pressure washing service provider or buy one. You can choose between electric pressure washers and those which run on gas. It is advisable to hire a pressure washer instead of buying one. Pressure washers in shops will be kept in a good running condition. If you end up buying one, you may have to spend time and money in maintaining it in a good condition.

You can also hire pressure washing services. These services have personnel who are trained in the field of pressure cleaning. They will do the whole task of driveway cleaning in a professional manner. They will also know the amount of pressure that has to be applied on different surfaces and will know how to use the machine.

If you want to use the pressure cleaner yourself, then it is very important to read the instructions manual carefully before using them. These machines have to be used with utmost precaution and care. Wear protective clothing as well. Never point the nozzle on yourself or at anyone. This might prove to be very fatal.

Always remember to clean the driveway thoroughly before using pressure washers. These machines are very effective in removing any type of dirt or stain on the surface. The entire process of driveway cleaning will take less time and effort. It is a very cost effective method of cleaning and will also reduce the risk of environmental pollution because there is absolutely no usage of chemicals. Pressure cleaners save a lot of water as well. So, if you are not interested in using chemicals, driveway cleaning with pressure washers can be just the right option to make.

How Does a Washing Machine Pressure Switch Work?

!±8± How Does a Washing Machine Pressure Switch Work?

Typically, washing machine pressure switches have a large sensing diaphragm that's about 60mm or so in diameter and three quick-connect male terminals. One connection is common, while the others are for normally open (NO) and normally closed (NC) connections. A set-point adjustment mechanism is built in (it's directly controlled by the 'water level' knob) and the switch opens and closes with audible clicks.

(Note that if the washing machine has digital controls, rather than a mechanical switch, it almost certainly uses an electronic variable pressure sensor to detect the water level. These three-wire sensors are easy to interface, but we'll leave them for another time).

Washing machine pressure switches directly control the hot and cold water inlet solenoids and so are rated for quite high currents - 15A at 230V AC is typical. So for low-voltage DC applications, the switches can certainly cope with (say) 5A. This means that, for most loads, a relay won't be needed.

Dishwashers use pressure switches that are similar to those used in washing machines. However, instead of having one switching point, they have multiple levels. For example, a two-position switch may switch at 10cm and 15cm of water, while a three-position switch may trip at 15cm, 25cm and 35cm of water.

These switches also look a lot like washing machine pressure switches, except they have multiple electrical terminals (six or even nine) and don't have external level adjustment. However, some have screwdriver adjustment for both the trip levels and the hysteresis.

When extracting the pressure switch from a washing machine, be careful that you don't also inadvertently

remove the adjustment mechanism it's often part of the bracket holding the switch in place! As for identifying the pressure switch, that's easy. Nine times out of 10, it's directly behind the 'water level' adjustment knob in the top control panel of the machine. If the machine's upside down or partly destroyed, follow the sensing tube from the base of the wash tub. And while you're at it, it's also usually worth scrounging the tube, which is often a high-quality plastic hose. You never know when it might come in handy.By contrast, dishwasher pressure switches are normally buried beneath the stainless steel drum. Because they're not externally adjustable, they don't need to be located close to the control panel.

Depending on your application, you might want your salvaged pressure switch to operate at pressures that are different to its standard range. That's not hard to do if you have a washing machine pressure switch, as they are quite easy to modify.In standard form, turning the adjustment control typically allows the trip pressure to be set to detect water depths anywhere from 9cm to 20cm. But if you remove the adjustment

bracket, you can access the internal spring which sets the sensitivity.For example, by using a very light spring (ie, one that provides just enough force to return the diaphragm to its un-triggered position when the

pressure is removed), it's possible to get a switch to trigger at just 5cm of water (~0.5kPa or 0.08psi). The external adjustment would then typically give a range of about 5cm to 7.5cm of water, but of course, this will vary depending on the unit and the spring used. Put in a stiffer spring and the adjustment

range becomes larger. While we haven't tried it, you could probably stop the switch from closing until you had 15 to 20kPa of pressure. Note,however, that the rubber diaphragm isn't designed to withstand these

pressure levels, so there may be some long-term reliability problems.

So what uses can be made of these switches? That depends on your imagination, but here are some suggestions:

(1). Controlling an electric water pump

- eg, to keep a container full of water. Just as in a washing machine, the depth of the water can be sensed from a hose connected to the base of the container.The advantage over a float switch is that the level is easily adjustable.

(2). Providing a low water level warning eg, the switch could be used to activate a buzzer or light if the liquid level in a tank drops below an adjustable point.

(3). Providing water level indication eg, by using a dishwasher pressure switch to activate LEDs or lights to indicate the water level in a tank. By using two dishwasher switches and adjusting their individual set-points, it's easy to have six levels indicated. However, you'll need a lot of wires to connect the switches to your display.

(4). Detecting vehicle movement using a washing machine pressure switch. The switch would be triggered by air pressure when the vehicle crosses a hose. Just remember to plug the end of the hose that's not connected to the switch! So there are four applications but there are lots more. It's certainly worth salvaging these very sensitive switches!
