Nozzle Selection
Spraying the spray paint and the flow rate is determined by the nozzle, so choosing the
right nozzle is very important and appropriate spraying construction sites can enhance the
efficiency of the flow is appropriate to reduce unnecessary waste of paint, and vice versa
Ran.Generally speaking, the viscosity of the coating in the choice of spray nozzle and the
flow rate, an important subject, when used by the lower viscosity of the coating, we usually
recommend the use of spray flow rate narrower and smaller nozzle Conversely, if coating
viscosity higher or solid components in a higher viscosity, we would recommend that you
use a wide spray and the rate of flow to the larger atomizing nozzle coatings, in the table
below is different coating viscosity we recommended by the nozzle aperture size.

1. seal oil and the protection of the pump body
Spraying in fixed before sealing oil will not only add to the role of sealing equipment,
and better ensure that the cylinder piston rod sealing life, and in long-term storage does not
work, let the body protection equipment inhalation solution is to prevent equipment corrosion
or rust
