Chongqing Changping Machinery Plant under the China Shipbuilding Industry Corporation sentinel production of navigation equipment mainly mechanical and electrical integration of military enterprises. Chang Ping brand airless spraying equipment widely used in aviation, aerospace, shipbuilding, machinery manufacturing, petrochemical, power and other industries. Its high-pressure airless sprayer, high efficiency of spraying, the film engaging and strong, long life, corrosion protection, low maintenance costs. Model: CP45B Scope ?? 1. Anticorrosion coatings difficult construction airless spray. Such as: Epoxy Mastic asphalt coating, modified epoxy coating, epoxy natural mica iron coatings, high solids solvent-free epoxy coating, super epoxy paint, polyurethane paint coated reusable and other new high-performance coatings . ?? 2. A variety of paint airless spray. Such as: chlorinated rubber paint, phenolic, amino, nitro, acrylic, architectural paint. ?? 3. It can be used in mines and other large gap between the high-pressure fluid delivery occasions. 4. Applicable to leather handbags, gift packaging, furniture, footwear, automobile manufacturing and other industries. The main technical parameters: ???? pressure ratio: 45: 1 ??????? ???? Displacement:? 32L / min ???? Weight: 78kg ???? Gross Weight: 95kg ???? Air source: 0.3-0.6MPa ???? Maximum output power: 27MPa ???? Dimensions:? 660 (L) × 570 (W) × 1140 (H) mm ???? package dimension: 720 ( Advantages L) × 630 (W) × 1210 (H) mm long flat sprayer: 1. Good quality paint, coating smooth and delicate, no brush marks. It will paint a pressurized spray atomized into fine particles uniformly distributed in the wall surface, so that paint on the wall a smooth, smooth, dense coating, no brush marks, roller marks, which is brush, roller and other methods can not match the original. 2. High coating efficiency. Single operation efficiency of spraying up to 200-500 square meters / hour, artificial brush of 10-15 times. 3. good adhesion, long coating life. It uses high-pressure spray, the atomization of the paint particles get strong momentum; kinetic energy emitted coating particles take up the pores in order that the film is more dense, so as to enhance the film and the wall of the mechanical bite force, improve coating adhesion effectively extend coating life. The film thickness, coating efficiency is high. The thickness of the artificial brush roll is uneven, usually in the 30-250 micron, paint utilization rate; without gas spraying is very easy to get a coating thickness of 30 microns. 5. easy reach corners and voids. As a result of the high-pressure airless spray, paint spray without air, paint brushes and other parts easily reach difficult corners, cracks and uneven, especially there are a lot of office ceiling air conditioning duct fire more suitable, it is difficult to brush construction. 6. The high viscosity of the coating can be sprayed, and hand brush, air spray, and so are only suitable for low viscosity of the coating. ? ???? Several common faults and troubleshooting common faults pneumatic airless sprayer is divided into two categories: air system failures and paint hydraulic system failure. ???? (A) air system failure: ???? 1. Pneumatic motor does not work. Check air supply is switched on, if regulator is opened. ???? 2. Air motor is not working properly. Should check whether the gas supply requirements (0.3-0.6MPa), whether to adjust the appropriate regulator, whether fully open. Second is to check whether the valve spring failure. Valve O-ring seal is reliable. ???? 3. Air motor whirring, insufficient pressure spray atomization bad. The direct cause of the failure is that the cylinder valve seal in wear and slider valve baffle badly worn, flat tie together well, resulting in leakage, piston thrust decreases, inadequate spray pressure. Replace all seals within the air motor. And 18 research plane of contact with emery paper flat member 17 pieces each other. With red lead powder end face fit check, if the two contact surfaces have a uniform red lead powder, indicating that it has polished. ???? 4. Suddenly stopping the work process (crashes), the system checks the gun discharged, painting tube composed of clogged should be cleaned or dredge. Check the coupling nut is loose, if loose should and tight. Check valve push rod nut is loose, if loose should and tight. Check whether the jack spring stiffness degradation due to lead to the top of power is not enough, not open the valve. Change should be based on matching the slide stays in different locations (top dead center or bottom dead center), adjust the jack nut, so ram position until the open valve. ???? Motor failure, it should be described in any one of the excluded, but not free to turn on the air motor. Because of the relatively high component reliability, long life, low probability of problems, so do not open. ???? (B) coating of hydraulic system failure: ??? 1. Such as air motor reciprocates normal, high pressure paint exclude normal. Check the paint bucket in the paint whether the suction air; check the exhaust system is clogged paint or foreign matter; the entire check whether the filter is filled precipitate; check paint pump V-rings (PTFE, leather ) is badly worn or loose; check paint suction valve port and plunger valve port Have precipitate blocked or severely worn seat; above all will lead directly to the high-pressure paint discharge is not normal. ???? 2. Close bleeder valve and gun, reciprocating air motor still have regular exercise. Cause there are the following two: (1) ??? V-rings installed at coating piston wear. The solution is to replace the seals. (2) ??? plunger valves, suction valves, discharge all the high-pressure valve port vent valve and other damage, the solution is to replace the piston assembly, the valve sleeve assembly, drain valve and ball. 3. If you find in a paint cup has a lubricating oil paints and solvents seeping described V-ring (PTFE, leather) within the pump housing is badly worn, should be renewed when you change from a few paint the pump group seals (PTFE, leather) replace together. NOTE: leather before replacing the seals should be fully immersed in vegetable oil. 4. When maintenance, all the non-metallic seals, shall not use strong organic solvent scrubbing, but not soaked in strong organic solvents. Three. 1 security alert. The airless sprayer high pressure industrial equipment. 2. High pressure spray gun toward others are forbidden or own any part. 3. High pressure paint can Shepo skin, injected into the skin will cause serious injury. 4. In the event of high pressure paint fired into the skin, be sure to specialized hospital treatment. 5. The airless sprayer must be used within its rated working pressure range. 6. A spark can cause a fire or explosion in the spraying operation area is strictly prohibited fire exists. 7. It must be reliably grounded when the airless sprayer to prevent static electricity. 8. When cleaning and maintenance, it should first cut off the gas source and paint pump relief.
