A kind of building coating spray gun
Technical field
The utility model relates to a kind of building coating spray gun.
Background technology
Spray gun divides three classes by spray gun operation principle: the gravity type simultaneously adopting coating gravity and fore vacuum suction, formula is sucted only with fore vacuum suction, paint pump is sent to the pressure sending type in spray nozzle front end portion coating, in addition, according to using dissimilar coating, also can be divided into priming paint spray gun, finish paint spray gun and small-sized spray gun, according to coating supply mode, paint spray nozzle bore, air use amount, the difference of spray pattern etc. divides, be divided into the formula of sucting, gravity type and pressure sending type three kinds suction, above formula spray gun, suct formula spray gun: principle utilizes high velocity air and makes spray gun parital vacuum, thus generation suction is drawn onto nozzle paint and is atomized ejection from kettle, mainly do large area spraying, benefit is that the atomization of paint is better, thickness and the glossiness requirement of paint film can be reached, the paint can sucting formula spray gun is positioned at the bottom of spray gun, paint spray nozzle generally compared with the centre bore of air cap slightly toward front protrusion, compressed air is from air cap centre bore, i.e. surrounding's ejection of paint spray nozzle, negative pressure is formed in the front end of paint spray nozzle, coating is atomized from sucking-off in paint can, the coating spray volume sucting formula spray gun is more obvious by the impact of dope viscosity and density, and have substantial connection with the bore of paint spray nozzle, the formula spray gun of sucting is applicable to general noncontinuity spraying operation occasion, gravity type spray gun: utilize gravity painting the nozzle below causing from kettle above, ejection is atomized again with wind-force.
Design in the past repairs for small size to use, be developed to comprehensive spraying now, benefit does can save paint when small size is repaired, the paint can of gravity type spray gun is positioned at the top of spray gun, the suction function that coating is formed by self gravity and paint spray nozzle front end sprays from paint spray nozzle, and with air mixing atomizing, the essential structure of spray gun is identical with sucting formula spray gun, but under identical spraying conditions, it is large that coating spray volume ratio sucts formula, gravity type spray gun is few and colour changing spraying operation occasion frequently for coating consumption, when coating consumption is many, can separately establish high-order paint can, be connected with spray gun with sebific duct, in this occasion, by changing the Height Adjustment coating spray volume of paint can, pressure sending type spray gun: pressure sending type spray gun supplies coating from the coating booster jar (or paint pump) separately established, the pressure improving booster jar can simultaneously to several spray gun supply coating, paint spray nozzle and the air cap central hole of this spray gun are positioned at same plane, or it is inwardly slightly recessed compared with air cap centre bore, negative pressure need not be formed in paint spray nozzle front end, pressure sending type spray gun is applicable to the many and different areas of activity of continuous spray of coating consumption, internal-mixing spray gun: have two air supply systems in internal-mixing gun body, namely with the compressed air system of coating mixed aerosol with in container for paint to the compressed air system that coating pressurizes, coating supply mode adopts pressure sending type, the centre bore of air cap is long olive shape, thus spray pattern is oval, this spray gun does not have side air hole and auxiliary air hole, spray pattern can not be adjusted arbitrarily, spray pattern is determined by the shape of the centre bore of air cap, change the fabric width of spray pattern, air cap must be changed, therefore, internal-mixing spray gun does not have spray pattern governor motion, other governor motions are similar to external mix spray gun.
Current existing spray gun easily produces electrostatic in use and causes potential safety hazard.
