These are some types of pumps that may be used but most the first 3 are not used too much with chemicals or soaps listed below.
|The rollers are thrown out trapping a section of water and then pushes it down the line.|
|The rotation of the motor cause the water to be funnelled in to the sections between the fins and forced in the centre hole forcing water out.|
|Vain style the veins slid in and out with the rotation of the motor water is trapped between veins and forced out similar to the roller pump.|
Now we need to introduce the last equation in the mix. All this blogging from the start boils down to this one thing "cleaning units". You now know how a washer works and what the key principals that make it work. So what are these cleaning units? Cleaning units are the total force that the water hits the partial of dirt and the power it takes to move it off the surface into the water stream. How do we calculate this now? CU (cleaning units) psi (pressure per square inch) GPM (gallons per minute) in this formula CU = PSI x GPM example 4000 psi pressure washer putting out 4 gpm =16000 cleaning units or 3000 psi @ 8 gpm = 24000 cleaning units. You can see here that the smaller pressure has more cleaning units then the larger pressure unit. Lets take the average house 40 psi and 10 gpm = 400 cleaning units you can see now why it takes a fraction of the time to clean with a pressure / power washer than your hose and that a pressure can be environmentally friendly. With this formula you can calculate the cleaning unit of all water pressure applications and you then can see that water energy weather gas or eclectic is being saved. Pressure washer are environmental friendly and for cosmetic cleaning professional contractors can get the job done better and quicker saving even more resources. The last thing I want to say is just because someone pulls up in front of your home or business with an eighteen foot trailer loaded with all types of tanks, washers, machines of all types and tells you how hot and powerful this is. We can blow that mold off your house with this kind of pressure this does not make them the best. Sometimes high pressure is called for and other times it is not, we here Cleaned by Pete want to sit down with you and talk about your needs and what is right for you.
I hope you have seen how things work, though brief and in the most basic form. There is more science in the pressure washing industry anymore it just not water squirting out a hose with incredible pressure. New products and methods come around all the time and we have tamed the this beast using it to its full potential. By influencing the psi, gpm, nozzles, pumps types and motor size we can now clean better, safer, quicker, and more efficient than ever before. But the cleaning contractor needs to under stand it also. Arm yourself with this knowledge and ask questions to protect your home and business against "fly-by-night" or "low-ball" individuals. Cleaned by Pete does their very best to stay up with all the new cleaning methods and equipment, please just ask us anytime to explain what we are doing or why. We are schooled in both pressure washing and soft washing ask us what is best for your home. I will talk about equipment and add on tools next time. Thank you for your interest and time. Knowledge is the key.
