Safety Warning ● This equipment must only be operated by trained personnel. ● Every equipment has a specific use. Please consult the agent of Dino-power if you have any questions. ● Never attempt to modify the equipment, nor exceed the maximum working pressure of the system. ● Check the equipment everyday. Maintain or replace old or broken parts immediately. ● Read the warnings provided by the manufacturers of coatings and solvents.
● Know the special harm of the coating you are using. ● Always wear protective glasses, gloves, clothing and musk recommended by the manufacturers of coatings and solvents. ● Actions of thrashing, knocking or throwing the cylinder of the coating machine are forbidden. If the cylinder is found broken, it should be replaced with a new one. It is also recommended that the cylinder should be replaced with a new one after being used for 5000 hours (or 3 years) to ensure the safety.
Dino-Power Airless Spraying Machine 1 General 1.1 Application Model DP6391 high-pressure airless spraying machines are the 3rd generation spraying equipments developed by our factory. They are applicable to industrial usage such as steel structures, ships, automobiles, railway vehicles, geology, Aeronautics and Astronautics and so on, for the spraying of new coatings or thick-film heavy-duty anti-corrosive coatings which are difficult to operate. 1.
3 outline drawing of Dino-Power Airless Sprayer (See Figure) Air intake The main working part of the sprayer is the double-acting air-driven high pressure painting pump. The reversing mechanism is the pilot all pneumatic control air-distributing reversing device with special form. When the compressed air flows into the cylinder, the piston moves to the upper part or lower part of the cylinder, forcing the upper or lower pilot valve to operate.
capacity of the equipped air compressor must be large enough. The length of the used air pipe must not exceed 5m. 4.2 Plug both the coating suction pipe and the discharge valve into the tank containing diluted coating, put through the air source, and adjust the air intake pressure according to the type of coating. To ensure safe use, the maximum air intake pressure must not exceed 0.6MPa, and is better to be kept at a value as low as possible as long as the atomization of the coating is good. 4.
5 Common Faults and Trouble-shooting Method SN 1 2 3 4 5 Generally, the faults of airless sprayer can be divided into two types: faults in air system and faults in coating system. If a fault occurs, it's prohibited to dismantle blindly. The fault should be analyzed and eliminated step by step as shown in the following table. Before that, the pressure switch should be dismantled and the air intake ball valve should be closed.
