Air spray gun design
Abstract: High pressure airless spray gun is a kind of to make use of the compredded air as power, not and directly use the compredded air carries on atomization to the coating, it presses pump to press the coating super - to the 10 Mpas Mpas-25ses with the super -, the high pressure coating passes nozzle of small spray gun hole the high speed spew out the atomization scatter into the most slender fog drop, at the same time atomization coating the corpuscle push into drive Tu Gong Jian's surface.
Make use of top speed air current but make air gun partial uvauum, as a result generate the vacuum force absorbs to spray Ju to take into atomization jet from the pot the paint and mainly make big area spray gun, the advantage is that the atomization of paint is better, can hit the thickness and water request of painting the film.The press barrel is the cylinder shape press container, generally use stainless clad steel or straight carbon steel creation, the barrel covers setup to adjust to press accesserieses such as valve, pressures gauge and safety valves etc., and the conditioning inputs the press of compredded air to hit the press of outputting the coating.Press barrel have of still install agitator air, the capacity of the wirking pressure barrel is for the 10 Ls, 20 Ls, and 40 L...etc..Press barrel the structure is simple, the maintenance is convenient, the coating outputs press more stable, scarcity of section is cleaning change a color inconvenience.
Air cap(air noozle), nozzle(coating nozzle) and vertex needle that compresses an air gun, habitually be termed three sets of compressing the air gun is decide air to spray Tu Zhuang mass key fraction.The gas moves a pair of septums pumps, is to make use of compredded air to make power, pass to change to make to get empty a barometric pressure action in the diaphragmatic seamy side toward the mrvhsnidm, while diaphragmatic outside side and pump body constitute a coating chamber that volume can change together.When the left side coating chamber volume became big to generate partial uvauum since the childhood, underneath an one-way valve opened, up an one-way valve locks, the coating in the coating barrel entered a left side coating chamber under the atmospheric pressure, but right surface coating chamber volume from greatly diminished, underneath an one-way valve lock, the coating generated press, the vertex opened over - an one-way valve discharged to pump a body.Two sides of double septum pump contain two coating chambers and be a volume from small become big, then another volume from greatly diminish, go round and begin again, go back and forth progress.So double the septum pump of every time back and forth have two coating suction and discharge and make the output efficiency of pump exaltation, and output contra more steady.Because the ratio of the input press of the compredded air and the output press of the coating is 1:1, the output press of the dimension convertibility coating of the input press of past conditioning compredded air
High pressure airless spray gun can use higher - viscosity coating, big area spray gun speed reach to the 4 ms 2/ms min-7s 2/min, the production efficiency is high.Spray has no compredded air vs the coating interfusion, paint fog rebound to fly a loose phenomemon compare air spray gun Tu Shao, lowered coating dissipation, improved public nuisances. High pressure airless spray gun's lacquer measures a little bit greatly and paints fog thin degree not enough soft, Tu Ceng's thickness doesn't easily control.The Jing decorates a spray gun of Tu Mo to cannot compare with air spray gun meticulous. Generally compliant unipole species viscosity the higher coating is as simple as shape, the surface accumulate a bigger work piece quantity production.Extensively used for a shipbuilding and gather vanning, the steel structure crafts, such as piece, outside wall inside the building and large piping...etc..
