Check out some of the non-landscape ways you can simplify everyday jobs with a pressure sprayer: 10 non-landscape Uses for Pressure Sprayers: Cleaning — Pressure sprayers are great for common household and commercial cleaning uses.
Great for fly spray, peroxide, show sheen and betadine applications Construction — Sprayers are helpful for washing away construction debris and can be used to provide a portable water source to use with dry cutting tile or masonry. A pressure sprayer is a chamber which is filled with a liquid which can be a lubricant, paint or chemical, then filled with compressed air to allow the liquid to be sprayed at pressure. Units are typically of cast iron or stainless steel design.
Cast Iron is used for lubricating liquids, and some weed killers, with stainless steel being used for spraying water based detergents to ensure water does not become discolored from corrosion, and the pumping of chemicals.
Flammable liquids must not be used with such equipment. Units can be fixed with a stand incorporating part of the design or on wheels for portability.
A industrial sprayer consists of a tank, safety valve, inlet nozzle and gauge. The sprayer is then sealed and an air line connected with the container being pressurized to its design pressure of anywhere between bar. Inside the cylinder, there is a small spring. To operate the pump, you pull the trigger back, pushing the piston into the cylinder. The moving piston compresses the spring, so when you release the trigger, the piston is pushed back out of the cylinder.
These two strokes of the piston, into the cylinder and out again, constitute the entire pump cycle. The downstroke, the piston pushing in, shrinks the area of the cylinder, forcing fluid out of the pump.
The upstroke, the spring pushing the piston back out, expands the cylinder area, sucking fluid into the pump. In a spray bottle, you need to suck cleaning fluid in from the reservoir below and force it out through the barrel above. In order to get all of the fluid moving through the barrel, the pump must only force the fluid up -- it cannot force the fluid back into the reservoir.
In other words, the fluid must move through the pump in only one direction. The device that makes this possible is called a one-way valve.
A spray bottle has two one-way valves in the pumping system: one between the pump and the reservoir and one between the pump and the nozzle. Typically, the valve between the pump and the reservoir consists of a tiny rubber ball that rests neatly inside a small seal.
The sides of the seal are angled so that the ball won't fall through. Depending on the design, either gravity or a small spring holds this ball against the seal so that the water passageway is blocked off when you are not pumping. When the piston moves out when you release the trigger , the expanding area of the cylinder sucks on the fluid below, pulling the ball up out of the seal.
Since the ball is lifted up, fluid is free to flow from the reservoir. But when you squeeze the trigger, the outward force of the moving fluid pushes the ball into the seal, blocking off the passageway to the reservoir.
Consequently, the pressurized fluid is pushed only into the barrel. In a spray mechanism, the one-way valve between the pump and the nozzle is a sort of cup, which fits over the end of the barrel.
