HVLP Spray Guns – Atomization Technologies – Part 2

Fundamentally, a HVLP firearm is as yet an air splash weapon as it involves air as its essential atomization force. Both HVLP and customary air splash firearms utilize similar two parts of compacted air, tension and volume yet in various amounts. The strain, which is typically noted as far as pounds per square inch or PSI and volume, which is noted as far as cubic feet each moment, are both vital for one or the other firearm to work.

Initially HVLP weapons where intended to utilize very high volumes of CFM that were created by turbines as opposed to blowers. These turbines conveyed, now and again, many CFM yet very little tension. To stay serious with the turbine HVLP weapons, the makers of the customary air splash firearms before long sorted out some way to switch their firearms over completely to HVLP utilizing packed air as opposed to turbine air. Today HVLP weapons are just about as normal as the old regular firearms.

HVLP innovation demonstrated that assuming you utilized a ton of volume of air rather than a ton of tension like regular weapons did, you couldn’t atomize coatings yet additionally do so more effectively. The productivity improvement was generally connected with the way that the atomized paint particles went at a more slow speed than paint particles that were atomized with high pneumatic force. We allude to this trademark as splash molecule speed. The higher the speed of the paint molecule the lower the effectiveness would be.

I like to utilize the similarity of a tennis ball and a concrete divider. The paint molecule is illustrative of the atomized paint molecule and the divider 350 Legend ammo from the divider. During air shower atomization the paint molecule can go at speeds more noteworthy than 30 feet each second or FPS. At the point when a similar covering is atomized with HVLP innovation, the FPS drops to 10 to 23 FPS. The more slow the molecule speed, the less return and over splash, the more productive the innovation will be.

Notwithstanding splash molecule speed, another trademark that influences firearms that utilization a great deal of volume of air, for example, HVLP is air damming. Here I like to utilize the similarity of a 2′ high by 2′ wide by 2′ profound box and blocks that are 1′ high by 1′ wide by 1′ profound. In this situation the crate is within a bureau and the blocks address a cubic foot of air from your firearm. Attempt to envision these blocks of air as they leave the shower firearm and enter the case. At the point when you splash into the crate you are filling it with the blocks of air. Within region of the container can hold 8 cubic feet or 8 blocks, yet the firearm you are utilizing is putting out 20 cubic feet each moment or 20t blocks each moment.

The outcome is that inside the space of seconds you are placing an excessive number of blocks into the container and those additional blocks are keeping you from placing in additional blocks and they are pouring out of control. The volume of air needs to head off to some place since it generally can’t go through the thing you are attempting to shower. The high volume of air from the weapon is forestalling more air and above all, the covering from getting into the case. This is an illustration of air damming and the higher the volume of air the seriously damming you will get.

Notwithstanding air damming there is the issue of air choppiness. Choppiness results from abrupt shifts in twist course and speed. This makes the airplane skip and move quickly in bearings that are not expected. Anybody that has at any point flown in a plane or stream has likely experienced it direct. As the atomizing air leaves the shower firearm it starts to connect with the covering and the encompassing air in the climate making choppiness. Furthermore, the air and covering cooperate with the substrates’ math making vortexes and flows which add to the choppiness. All firearms make their own choppiness during atomization yet weapons with high atomizing tensions or high volumes of air will make more disturbance than firearms that utilization low tensions and extremely low volumes of air.

So beside these attributes that are shared by ordinary air shower, HVLP, LVLP and RP weapons, one ought to likewise grasp the advantages and impediments of HVLP. Generally the advantage is diminished covering use as HVLP has been demonstrated to build ones’ exchange effectiveness. Basically move productivity is than percent of paint solids that leave the splash weapon during atomization that really end up on the substrate and not in the shower stall channels, corner dividers or the stalls floor. A few producers have seen covering investment funds per square foot of up to half while others may just see reserve funds of 15 to 20%. Much relies upon your covering, your current circumstance, your finishers and how well your customary firearm was set up in any case.

Concerning the constraints, HVLP weapons utilize considerably more CFM than traditional firearms. This implies that you will in all probability be paying something else for power to run your blower, best case scenario, or you could have to move up to a bigger blower to say the least. Albeit the general atomization of HVLP has enormously improved, atomization quality can be adversely impacted by high consistency or potentially high stream rates. Most states expect that HVLP weapons be restricted to 10 psi at the air cap since pressures higher than that start to considerably diminish the firearms’ proficiency. So on the off chance that your material is gooey or on the other hand assuming you are running high stream rates you might be hampered by this 10-psi limit or by the declining effectiveness would it be advisable for you surpass 10 psi.

Low Volume Low Pressure

To assist clients with restricted compacted air accessibility, some weapon producers have presented Low Volume Low Pressure firearms. These weapons are intended to decrease splash molecule speed like HVLP firearms, however can really utilize less air than a regular firearm. This can assist with diminishing the high power costs related with the high cfm request of HVLP firearms. Notwithstanding, it is suggested that you assess these weapons completely for finish quality and productivity before naturally changing to this innovation. The cash you save in power might be offset by a misfortune in effectiveness or finish quality. On the other hand, you might observe that some of they are more effective or give you a superior completion and get a good deal on your electric bill. The best way to be certain is to attempt them at your office, with your coatings and your finishers.

One more benefit of this innovation is their capacity to convey pressures significantly higher than HVLP. For organizations or businesses that are not confined by state ecological guidelines concerning the 10-psi limit, these weapons can deal with higher viscosities and stream rates than HVLP firearms yet no doubt at lower efficiencies. Notwithstanding, the efficiencies are typically altogether higher than Conventional Air Spray. LVLP firearms are viewed as HVLP agreeable however provided that worked at 10 psi or less at the air cap.

The entirety of the above low liquid tension, air splash advances are accessible in siphon, gravity and strain feed designs. In any case, remember the restricted siphoning skill of a portion of these firearms, particularly on the off chance that your material is thick or on the other hand on the off chance that you want to shower at high stream rates. You must ensure that the firearm you select can be worked inside the consistent strain range (10 psi for HVLP) or that it is perceived as an agreeable innovation, on the off chance that you are expected to do as such by any state ecological guidelines.
