Pressure Washer

Hi, and thank you for your help. Has anyone made/created a pressure washer. Here is link: http://www.nextag.com/SIMONIZ-1300-PSI-Pressure-582276230/prices-html. I am wondering if someone has made somthing small, like the one in the link.

pressure gauge

HelloI have a heat press that has no pressure gauge. I am trying to figure a way to add a manual one.So when I close the upper platen to the bottom I can tell how much pressure is being exterted on to a substrate that I am pressing. If a way coudl be found to do it while being able to withstand 400+ degrees F that be great but if not doing it cold shouldn't matter.Thickness would have to be less than a inch.I was thinking a air bulb like on a blood pressure cuff and some type of gauge but not sure about that.Anyone got any good ideas.THanksMark

Pressure Washer? Answered

I would assume it can't be, but it would be really lucky if a pressure washer could fill an air tank to the pressure the washer is rated for.  So can a pressure washer that says 5000 psi really fill a tank to 5000 psi with the right fittings.  It probably won't be breathable or paint ball worthy but is it plausible.

Homemade Pressure Washer Answered

Hey guys, I had a lawnmower which broke at the blades, so I thought I'd turn it into a pressure washer. So  I welded up a frame from a old hand trolley and bolted on the engine. While I was looking around for a pump I realized that the engines made for pressure washers cannot be used for mowers. Is this the case the other way round?, Will a pump work on this engine? I'm 100% sure one will fit. Has anyone ever attempted/done this conversion? Thanks in advance!!

Low hot water pressure

I the past 4 months I have replaced the water heater, water softener, and the pressure tank. Everything was working fine until I developed a leak in a PVC elbow from the outside water supply As soon as that was replaced and I turned the wter supply back on my hot water pressure dropped to almost nothing in all of the faucets. I am thinking some scale got lodged in the outflow pipe from the water heater and I need to apply high pressure air from one of the faucets to force this out.

Pressure Sensor Feedback loop

I'm trying to build something that will more or less maintain a constant, but adjustable level of pressure, probably driven by an electric motor. I've seen pressure-sensors on this site that increase conductivity with more pressure applied to the sensor, but mechanically I can't think of any way to get my device to work without a pressure sensor to decrease in conductivity with added pressure. Sadly I don't know enough about electrical components or circuitry to make it work with the former. If anyone here would happen to know how I could create such circuit, or can suggest of a purely mechanical alternative I would appreciate it.

Handheld Flamer- No pressure tank?

Alright fellow instructables, here's the lowdown: I'm currently attempting to build a hand-held flamethrower that you only need one hand to use, sort of like a pistol. However, when I was looking at a diagram for a regular Army flamethrower, I realized something: The fuel tanks on the flamethrower werent pressurized, and the fuel was pushed out using a pressurized tank that was fed into the fuel tanks. Now here's my question: Because I'm just trying to make a little hand-held that I DON'T need to shoot 50 feet, can I skip the pressure tanks and just jump to a commercial fuel source, like one of those miniature camper stove fuel tanks? Thanks Outdoors!

Pressure system leak alert

Hi, from a brand new poster. I have a farm water pressure system in a shed, mostly watering troughs for stock. When there is a slow or fast leak, I waste water, at expense.  They could be broken valves to pin holes in pipes. The pressure is system is run by 240V mains, (Australia) via a plug into a socket, as normal. There is a smart meter in the shed. Stock generally don't drink much from midnight to 5am. If there is a constant leak, the pressure system will cycle during the night. What I want to know is, is there a way to trigger an indicator that shows the pressure system is cycling overnight between set hours (12 - 5am)?  Eg, a few cycles may be acceptable, 5-10 are not.  When noticed, I can go to the shed, further investigate, and reset the trigger. I also have capacity to read water pressure at my house, on the same system, which will fluctuate as the pressure system cycles.  If I could easily track and record the pressure fluctuations, I would also know if there is a leak. Apparently I could install a flow meter with a wifi or sms system, but that sounds expensive and complicated.  I don't use a flow meter as it is not needed. So we have power usage, pressure switch triggering, water flow, water pressure , noise, and pump heat as indicators, at the pump shed. I have line of sight to the shed from my house, about 500m away.  I could see any alert lights daily, both at dark in the evening, and in morning daylight.  They could be 240V or battery powered.  I am currently tapping into the pressure switch to run a light.  The problem is 1. I have to be awake then to check a light. 2. it takes time for long cycles to occur. For all I know there may be something available already, which I have not yet found. I don't have need, yet, to be alerted as an absentee manager (eg sms alert). I know there are fancy systems available for sale for that. Any technical ideas would be most welcome, thanks, including combinations of the engineers parameters - cheap, strong, quick.

Pressure, vacuums, and the on earth equivalent?

One atm is equivalent to about 14.7 psi.  Does that mean that if one was in a perfect vacuum a vessel sporting 1 atm would need only hold the pressure of 14.7 psi?  It seems to me that in space (not a perfect vacuum) a craft would only need to hold maybe 12 psi (of course when messing with human life I would definitely allow for 150 to 200% tolerance, but in the end 24 psi still isn't very much is it.  Is there more to it than this, or are all those quotes about how hard it is to deal with a vacuum and how things must be super strong a little over blown.  Going just 11 meters under water exposes you to a little over double air pressure at sea level.  Someone in just a diving suit has been to over 60 times atmosphere and the deepest submarine dive I could find was 1083 atm at around 11000 m.  It just seems to make holding out a vacuum a little overrated.

Plumbing Help

Help! We just moved into a new house and the water pressure seemed pretty high, especially at the bathroom sink (it sprays everywhere when turned on full).  I tested the pressure at an exterior hose bib and it measured at 81 psi.  It also measured at 79 psi at the cold water supply valve for the washing machine.  I sent the pictures listed here to my father-in-law, who seems to believe that I can adjust the pressure with the current plumbing system.  I looked everywhere for a pressure regulator in the line, but couldn't find one.  The only thing I can think of is that he believes the gray valve above the meter is a glob valve and can be used to throttle down the pressure.   Any help would be appreciated!

I am looking for a sensor that measures "pressure" but I don't know what to look for.

I have an idea, nothing revolutionary, but it would perfectly solve a problem that I have in my woodworking shop. I need to be able to tighten a very small toothpick-sized piece of wood in a small meral vice, to a very specific level of "squeeze", and then release the vice, and repeat that exact "level of squeeze" over and over. Can someone point me in the right direction of what these "pressure measuring devices" might be called? Ideally I could use this pressure gauge (sensor) in tandem with a small display and an Arduino, Raspberry pie, or some other logic device that can interpret the output from the pressure sensor and send that output to the little display.Thanks for your help guys!

How to store hydrogen under pressure

I've made several hydrogen generators via electrolysis, but every time I failed to store the generated hydrogen under (some) pressure. In this-> http://www.youtube.com/watch?v=m9Q6gDKP2R0 video they used an emptied fire extinguiser to store the hydrogen. The only problem with this is that they use a chemical reaction to generate the hydrogen whereas I want to use a renewable source (electricity).  I have a compressor so I could use that to generate the pressure. Has anyone got any ideas on how I could store hydrogen under pressure?

detergent feed for electric pressure washer

I know there are exspensive or maybe just newer PW's that you can add detergent to but not mine. It's just one of those hardware store 1300 PSI electric models. I'm just thinking that there has to be a way to provide some detergent to my spray. I think tapping into the feed hose with a siiphon rig would be a bad idea cuz then you'd be sending the soap through the pressure pump. It's have to be on the other end but there you have high pressure hose you might not want to cut. My thoughts flow along the lines of some sort of connector pipe comming off the output side that goes between the unit and the spray hose connector. You could make it a bit larger to hold like a dishwasher table or rig some sort of siphon hose (like a hose end sparyer) maybe. I'm not sure. My main thought isn't to use the soap for pressure CLEANING but to use the much greater reach of the pressure sprayer to spread the soap/cleaning solution farther - like up to second story siding. thanks

The second one is difficult to find something on, whilst there are ways to do so, I can't seem to figure a way without using electromagnets(which may overheat)

How to store hydrogen at low pressure?

What is the most practical and cost efficient way to make a 10m3 gas bag for the storage of hydrogen? I am planning to store pure Hydrogen (made from water electrolysis) in an outdoor area, a bit like the way biodigestor gas is stored in low cost, small scale installations. My concern is the high effusing nature of the gas through membrane material. My first thought was to use reinforced PVC like that used for truck tarpaulins but I can't find any info on effusing rates verses other materials. Ideally the gas would be able to remain in the bag for a maximum 2-3 weeks until needed. This is an experiment on the practical applications of locally produced hydrogen, so I hope to be able to follow up any advice by constructing the gas bag and reporting back with the project progress. Any thoughts and advice would be gratefully received!
