Abstract

The invention relates to a double-head pneumatic spray gun testing method. The double-head pneumatic spray gun testing method includes the steps of A, testing service life of the spray gun, namely, conducting cycle usage test for 5,000-20,000 times by an automatic tester; B, subjecting a spray gun body to pressure resistance testing, namely, injecting air with the pressure of 8 KG into the gun body for 60 minutes; C, testing airtightness, namely, establishing connection with an air pipe joint at the air pressure of 3-5 KG, observing the number of bubbles rising from all screws respectively when the gun body is immerged into water, and observing whether or not the bubbles rise from a gun nozzle; D, establishing connection with liquid with the pressure of 4-6 KG and observing whether a liquid pipe joint leaks liquid or not; F, conducting spray testing, namely, observing atomization effects. The double-head pneumatic spray gun testing method is capable of testing airtightness of multiple portions of the spray gun and can be more thorough in spray effect detection by testing different shapes of spraying effects.

Description

technical field

[0001] The invention relates to the field of equipment testing methods, in particular to a testing method for a double-headed pneumatic spray gun. Background technique

[0002] The spray gun mainly uses air pressure to produce atomization effect and sprays through the nozzle of the spray gun, and the spray body passes through the air pipe to the nozzle mouth to spray atomized spray. Higher air pressure will obtain greater spray energy and finer atomization effect. The most important thing about the spray gun is to control the spray air pressure, and the change degree of the air pressure will greatly affect the quality of use.

[0003] At present, spray guns have studied many shapes and structures around the same or similar principles of use, but there is no good detection method for the detection of air tightness of spray guns and the detection of spraying effects. The air tightness and spraying effect of the spray gun are the most important performance indi...
