There are several steps to cleaning electric high-pressure airless sprayer.
Turn off the airless spray gun safety.
Turn off the sprayer equipment power switch and use the return valve to release the pressure in the equipment (just turn the return valve counterclockwise).
Remove the nozzle and soak it in a small bucket with clean solvent or water and rotate the return valve counterclockwise (note: the paint sprayer return valve cannot be unscrewed in its entirety).
Lift the airless suction tube so that it leaves the paint bucket and open the equipment so that the paint in the equipment flows out from the return tube.
Prepare a metal bucket with water or clean solvent, please do not use industrial alcohol to clean the equipment, industrial alcohol will gum up the internal seals of the equipment.
Put the suction tube into the metal bucket, make the water or solvent circulate in the equipment for 2-3 minutes, and turn off the power switch.
In order to save the remaining paint in the paint tube, pull down the trigger by aligning the nozzle to the wall of the paint bucket, tighten the return valve clockwise, at this time, you need to pay attention to the splash of paint, when the solvent or clean water appears in the paint, close the spray nozzle and put the nozzle into the metal bucket.
Knock down the trigger to make clean solvent or clear water circulate in the spray equipment for 2-3 minutes, turn off the power switch.
Lift the suction tube to make the suction tube leave the metal barrel with clean water or solvent, and set the return valve in the return position. Turn on the power switch to make the solvent in the equipment discharged from the reflux tube.
Prepare some clean solvent or water and use low pressure to make it circulate in the paint spray equipment until it is clean. If you use water to clean, you can add a little equipment protection liquid in the water, so that it can reduce the possibility of rusting in the equipment.
Take out the suction tube from the metal barrel with solvent or water and clean the airless suction tube strainer.
Check the equipment and nozzle filter screen for blockage and damage, and clean or replace if necessary.
Remove the nozzle from the pail containing solvent or water and gently brush the nozzle clean with a soft brush and blow clean with compressed air and store in a dry place.
WARNING: Since this equipment airless sprayer is a high pressure device, please read the cautions and warning labels on the operation manual carefully when operating.
The cleaning and maintenance methods and steps of airless paint sprayers:
1. After the spraying operation is over, the airless sprayer should be cleaned immediately to remove the residual paint in various parts where the paint flows to prevent it from hardening and causing blockage. When cleaning, just replace the paint with the corresponding solvent and spray according to the operation, until all the paint in the body, high-pressure pipe and spray gun is sprayed out.
2. After using the airless paint sprayer for a period of time, it is necessary to clean the filter screen of the spray gun. The method is: remove the movable joint and the buckle, unscrew the handle of the airless spray gun, take out the filter element in the handle and clean it, and then put it back in order, Tighten. If the filter element is found to be damaged during cleaning, it should be replaced with a new airless sprayer filter element.
3. If the spraying is not smooth during the spraying process, check and clean the suction filter in time. Generally, the airless suction filter should be cleaned after each shift.
4. Regularly check whether the fasteners are loose and whether the seals are leaking.
5. Under normal circumstances, after three months of continuous use of the airless sprayer machine, open the pump cover to check whether the hydraulic oil is clean and lacking. If the hydraulic oil is clean but missing, add it; if the hydraulic oil is not clean, replace it. When replacing the hydraulic oil, first clean the oil cavity of the pump body with kerosene, and then add hydraulic oil with a volume of about 85% of the oil cavity, which is equivalent to about 10mm between the oil surface and the top of the pump body.
5. If you still need to use it the next day after each use, please do not drain the liquid in the suction pipe, body and high pressure hose pipe, or do any disassembly, just soak the suction pipe and discharge pipe spray gun in the It can be stored in the corresponding solvent; if it needs to be stored for a long time, the liquid in the machine should be drained, and it should be packaged and stored according to the new paint machine state.
What is airless paint spraying? Simply put, airless paint spraying simply uses material pressure without air. An electric or pneumatic pump or gasoline engine puts the material under pressure and forces a specified amount of material through the tip hole at a maximum pressure of 250 bar. This converts the material into a spray.
Use the pump to bring the paint material to a pressure of up to 250 bar and then pass it through the airless spray gun.
When the airless paint valve (gun) is opened, the paint is forced through the opening in the airless nozzle of the required size. Atomization is created by the pressure difference between the coating material and the atmosphere.
The flow rate and spray width are determined by the airless spray tip.
Various materials can be sprayed with airless paint sprayers. We have summarized them here:
Water-based and solvent-based paints, varnishes, lacquers, oils, separators
Synthetic resin-based coatings, PVC coatings, 2-K lacquers
Primers, fillers
Fireproof coatings, anti-corrosion coatings
Emulsions, emulsion paints, adhesives, sealants
Masonry coatings, roofing coatings, flooring coatings, silicone coatings
Fillers and other high viscosity materials
Airless spray guns are a type of paint application system that use high pressure to atomize the coating material and propel it onto a surface without the need for compressed air. The wall putty spray gun are equipped with a pump that pressurizes the coating material, forcing it through a small opening in the spray tip, which creates a fine mist that is sprayed onto the surface.
Airless spray gun for sale are widely used in commercial and industrial applications because they offer several advantages over other spray systems. First, they can be used to apply a wide range of coatings, including latex, enamels, lacquers, and stains, at a much faster rate than traditional spray systems. Second, the high-pressure atomization of the coating material produces a finer spray pattern that results in a more even and consistent finish. Third, airless spray guns can be used to apply coatings to surfaces with irregular shapes and textures, such as concrete, wood, and metal.
Airless spray guns are available in a variety of sizes and configurations, from handheld units for small jobs to larger, more powerful units for commercial and industrial applications. They are also available with a range of spray tips that can be swapped out to adjust the size and pattern of the spray. However, custom spray guns can be more expensive than other spray systems, and they require more maintenance and cleaning to prevent clogging and ensure optimal performance.
Choosing the right airless spray gun depends on various factors such as your project requirements, the type of materials you will be spraying, and your budget. Here are some steps to help you select the right airless spray gun:
Determine your project requirements: Consider the type of surfaces you will be spraying (interior walls, exterior surfaces, furniture, etc.), the size of the area, and the type of material you will be using (paint, lacquer, stain, etc.). This will help you narrow down the selection.
Consider the PSI (pounds per square inch) rating: The PSI rating indicates the pressure at which the spray gun operates. Higher PSI is suitable for larger surfaces and thicker materials, while lower PSI is better for smaller projects and delicate materials.
Look for adjustable pressure and flow control: Having the ability to adjust the pressure and flow will give you better control over the spray pattern and thickness. This is particularly useful when working with different materials or surfaces.
Check for airless nozzle options: Different airless spray nozzles produce different spray patterns (wide, narrow, circular, etc.) and allow for different paint thicknesses. Ensure that the spray gun you choose has compatible nozzle options that meet your project requirements.
Consider the gun's weight and ergonomics: If you have a large project or will be using the paint spray gun for an extended period, consider the weight and ergonomics of the gun. A lightweight and well-balanced spray gun will help reduce fatigue and improve maneuverability.
Read reviews and compare brands: Research different brands and models of airless spray guns, read customer reviews, and compare their features, durability, and performance. This will help you identify reliable and reputable options.
Consult professionals or experts: If you still have doubts or specific questions, consider consulting with professionals in the field or experts at a local hardware or paint sprayer store. They can provide personalized guidance based on your specific needs.
By considering these factors and doing thorough research, you can choose the right airless spray gun that will meet your project requirements and help you achieve the desired results.
