Airless spray scribing machines are expensive, and after a period of use, maintenance is indispensable. Regular, compliant maintenance can greatly extend the service life of the equipment and reduce the frequency of accessory replacement. However, the maintenance of the spray scribing machine involves many links such as inspection, disassembly and replacement of wearable parts, and there are certain requirements for operation. In order to help you maintain your equipment efficiently and comprehensively, we have summarized some tips for the routine maintenance of spraying equipment today for users' reference.
Routine Maintenance
Routine maintenance of airless spray scribing machines
1. Air compressor oil level
If the oil level of the air compressor is too low, it will cause the air compressor to heat up, damage the piston and piston rings, etc., and it is necessary to check regularly and add oil in time.
2. Gasoline engine oil level
If the gasoline level of the gasoline engine is too low, it will cause the engine to stall, so it needs to be checked regularly and gasoline added in time. The oil of the gasoline engine needs to be checked and changed regularly, otherwise it is easy to cause the engine to pull the cylinder.
3. Hydraulic oil level
If the hydraulic oil level is too low, it will cause the double pump to run at different speeds and unstable pressure, so it is necessary to check regularly and add hydraulic oil in time.
4. Whether there is water in the gas storage tank
There is moisture in the gas storage tank, and the water will enter the glass bead tank through the gas pipe, which will cause the glass beads to be damp and blocked, affecting the operation of the equipment, and need to be checked regularly and emptied in time.
5. Whether the nozzle is worn or damaged
The nozzle is worn or damaged, which will cause material costs, line shape is not up to standard, etc., and it needs to be checked regularly and replaced in time.
6. Whether the return valve is working properly
If the sealing ring in the return valve is damaged, it will cause unstable pressure, material leakage, and substandard alignment, so it is necessary to regularly check and replace the new sealing ring in time.
7. Whether the piston pump is tight
The repair kit assembly inside the piston pump is not damaged but not tight, which can cause material leakage. If the repair kit components are found to be damaged, they need to be replaced with new repair kits in time.
8. Belt tightness and wear degree
If the belt is too loose, it will cause insufficient air pressure, insufficient oil pressure, and substandard linear shape. Too tight a belt can increase the load on the engine and accelerate belt wear. It is necessary to regularly check the tightness and wear, and adjust and replace the belt in time.
9. Whether the hose is worn
The hose plays the role of pressure preservation and stabilization, if there is wear, it is easy to cause the hose to burst, and it needs to be checked regularly and replaced in time.
10. Filter screen
The filter screen is blocked, damaged, deformed, etc., which will cause the spray gun, nozzle, line shape is not up to standard, etc., and needs to be checked regularly and replaced in time.
11. Suction port filter
The filter at the suction port is damaged, deformed, etc., which will cause insufficient filtration effect, inhale large particles, and affect the operation of the equipment. The blockage of the suction port will affect the insufficient suction and the spray width is unstable, so it needs to be checked regularly and replaced in time.
12. Sealing oil
Add sealing oil to the upper sealing oil cup to ensure that the plunger rod is lubricated during operation to protect the upper sealing ring and reduce wear, which needs to be checked regularly and added in time.

Priority Maintenance
Focus on maintenance
1. Gasoline engine spark plugs
The spark plugs of gasoline engines have serious carbon deposits, which will cause the gasoline engine to fail to start, and need to be checked and replaced in time.
2. Air compressor air filter
When the air compressor is operating, it will suck in dust, glass beads and other small objects, and the air filter element is seriously polluted, which will cause insufficient pressure, so it needs to be checked and cleaned regularly, and replaced if necessary. If you work in an abnormally dirty environment, you need to increase the frequency of inspection, cleaning, and replacement.
3. Hydraulic oil and hydraulic oil filter
Hydraulic oil and hydraulic oil filters are seriously polluted and will damage the equipment, so they need to be inspected and cleaned regularly, and the hydraulic oil and hydraulic oil filters should be replaced if necessary. If you work in an abnormally dirty environment, you need to increase the frequency of inspection, cleaning, and replacement.
4. Gasoline engine air filter
The gasoline engine air filter element is too dusty, which will not be easy to start, so it needs to be checked and cleaned regularly, and replaced if necessary. If you work in an abnormally dirty environment, you need to increase the frequency of inspection, cleaning and replacement.
If you want to attack the task first, you must first sharpen the tools. Complete maintenance and good operation of marking equipment is the basis for the smooth development of road marking projects. Especially for spraying and marking equipment, we must abandon the erroneous concept of "only use but not maintain, only repair but not protect", and have special personnel and regular maintenance. In this way, the function of the scribing equipment can be maximized and more value can be created for the owner.
