A polyurea spray machine is a significant investment for any contractor. Whether you are using a hydraulic model like the Reanin K7000 or a portable pneumatic unit like the K2000, regular maintenance is the key to preventing downtime and ensuring consistent spray patterns. In this guide, we’ll walk you through the essential steps to keep your equipment running at peak performance.
The most critical maintenance happens at the start and end of every workday.
Check the Lubrication Oil Cup: For proportioning pumps, ensure the lubrication oil is clean and at the correct level. This prevents the ISO (Isocyanate) from crystallizing on the pump shaft.
Inspect Filters: Check the Y-type filters on the suction lines. A clogged filter will cause pressure imbalances, leading to "off-ratio" foam.
Gun Maintenance: At the end of the day, clean the spray gun thoroughly. Use a proper solvent and ensure the mixing chamber and nozzle are free of residual material.
Once a week, perform a more thorough inspection of the entire system.
Check the Feed Pumps: Ensure the air supply to the T1 or T2 feed pumps is dry and lubricated.
Inspect Heated Hoses: Look for any signs of wear, leaks, or loose electrical connections. Since polyurea requires strict temperature control, a faulty hose can ruin your application.
Tighten Connections: Vibration during operation can loosen fittings. Check all hydraulic and air connections.
Inspect the Motor and Hydraulic System: If you use a hydraulic machine, check the hydraulic oil level and look for any discolouration in the fluid, which could indicate contamination.
Clean the Primary Heaters: Over time, sediment can build up in the heaters. Periodic flushing helps maintain efficient heating cycles.
Pressure Imbalance: If one side is consistently higher than the other, check for a blockage in the gun or a dirty filter.
Crystallization: This is the "silent killer" of PU equipment. Always keep Isocyanate (Side A) sealed and away from moisture.
By following this maintenance schedule, you can ensure that your Reanin spray machine provides years of reliable service. Remember, 15 minutes of cleaning today can save you 5 hours of repair tomorrow.
