The Main Points for the Nozzle Purchasing
Published on January 4 2013
Factors for the selection of nozzle
There are several of nozzles and a range for the optional nozzle is wider, and we should simply grasp: 1. Media, 2. Pressure, 3. Traffic, 4. Spray angle, 5. Structure and purpose. And these five points can basically complete 90% of the nozzle replacement. Generally, the degreasing and washing step of the nozzle can select spray gun nozzle with strong impact force: take the segment-type nozzle as an example, it is better choose the injection angle of 60 ° which has a larger impact strength; while the phosphating step can choose centrifugal nozzle with good atomization, uniform grain and fine water and the weak impact, such as the cone nozzles, the best distance of the nozzle is 40cm ~ 50cm which can disperse and atomize the liquid. The nozzles are arranged on the nozzle and we can take two forms of channel types in parallel and cross.
Flow and pressure, spray angle and coverage are proportional to the relationship. Any nozzle injection purpose is to maintain continuous connection between the bath and the workpiece, the flow of this factor is more important than the pressure. The temperature of the liquid does not affect the performance of the spray nozzle, but it affects the viscosity and specific gravity, but also influences the choice of materials. The nozzle material should be determined based on the chemical properties of the bath. For the non-corrosive bath, it can be casted in bronze or plastic die-casting according to the ease of processing. To prevent corrosion, non-metallic materials can be used, and for the strong etching bath of sulfuric acid, hydrochloric acid, the nylon plastic can be used. The nozzle has a certain impact should be used in small-angle nozzle and flat fan nozzle is used for cleaning, degreasing and cooling. Conical nozzle is suitable for bleaching cream, the surface layer, phosphide, humidification, dust, and so on. It should be installed in the reservoir paint cylinder in order to prevent the precipitation, because the agitation to ensure a uniform mixing of chemical solution.
The principle of nozzle
Nozzles mix the liquid and gas uniformly by the internal design. The adjustment of liquid flow rate can also produce the same desirable spray without changing the air pressure and the pressure of the liquid. Every spray device consists of the air cap and fluid cap, which can provide the two kinds of spray patterns: the fan and the circular, and has a wide flow range. The nozzle members can be interchangeable, and the fine spray droplets generated by the nozzle can play an excellent humidifying effect on the surrounding environment.

Spray nozzle is of high degree accuracy and intractable. On the basis of spray nozzle processing, Changyuan Co., Ltd. is developing precision finishing of hareware parts industry. Changyuan Co., Ltd. has twenty Japan-made CNC automatic lathes whose precision can reach 2 micro or below and several sets of five spindle lathes whose orifice precision can reach 0.10mm. All the advanced equipments ensure that we can supply good quality products to our customers.
