2. Istruzioni di sicurezza

Il rispetto delle seguenti linee guida di sicurezza è fondamentale per prevenire lesioni e danni all'attrezzatura.

• Prohibited Test Liquids: Do not use water or diluents such as ketone, Tianna water, or xylene for testing the polyurethane injection machine. These substances can cause damage to vulnerable parts, lead to stuck pumps, or burn out components due to lack of pressure.
• Recommended Test Liquid: Always use oil or edible oil for machine testing.
• Controllo della pressione: During testing, the pressure range must be controlled within 400 units (e.g., kg/cm² or psi, depending on the gauge scale).
• Manometro di monitoraggio: When operating the machine, continuously monitor the pressure value on the pressure gauge. Ensure the pressure does not exceed the yellow scale area on the gauge. Exceeding this limit can cause component deformation or failure.
• Dispositivi di protezione individuale (DPI): Always wear appropriate PPE, including safety glasses and gloves, when operating the machine.
• Ventilazione: Ensure adequate ventilation in the work area, especially when using grouting materials that may emit fumes.
• Alimentazione elettrica: Collegare la macchina a una presa di corrente con messa a terra e con la tensione correttatage and frequency (220V AC/50Hz).
• Connessioni sicure: Before operation, ensure all connections, including the high-pressure pipe and nozzle, are securely fastened to prevent leaks or disconnections under pressure.

• Maniglia per il trasporto: For easy transport and positioning of the machine.
• Drive Machine: The electric drill unit that powers the pump.
• Material Barrel: Container for the grouting material. Made of corrosion-resistant ABS plastic.
• Manometro: Displays the current operating pressure. Features a shock-resistant glycerin filling and a double dial for high precision.
• Three Links: Connects the pump to the high-pressure pipe.
• Pompa: High-precision stainless steel alloy pump core, offering good sealing, corrosion resistance, and wear resistance.
• Switch Valve: Controls the flow of grouting material.
• Ugello: Directs the grouting material into the injection point.
• High Pressure Pipe: Durable, explosion-proof pipe designed to withstand high pressures.
• Clamp: Secures the drive machine to the main unit.
• Scatola del cambio: Transmits power from the drive machine to the pump.

3.2 Caratteristiche principali

• Materiali di alta qualità: The machine features an ABS plastic barrel that is corrosion-resistant and durable. The pump core is made of stainless steel alloy, ensuring high precision, good sealing, and resistance to corrosion and wear for a long service life.
• Potente ed efficiente: Equipped with a high-performance, all-copper wire motor electric drill, providing strong power, fast heat dissipation, and low noise. It can achieve a working pressure of 0-50 MPa in seconds, with a maximum supported pressure of 700 kg.
• Environmental Protection and Low Noise: The design minimizes environmental pollution and operates with low noise levels. The electric drill's ventilation holes ensure rapid heat dissipation.
• Effective Penetration: Due to continuous high pressure, the grouting agent effectively penetrates concrete structures, filling micro-cracks, micropores, and capillaries.

4. Impostazione

Before initial use, it is essential to perform a machine test to ensure proper functionality and to familiarize yourself with the equipment. This test should always be conducted using oil or edible oil, never water or diluents.

4.1 Initial Machine Test

1. Versare l'olio: Pour oil (edible oil is also suitable) into the material barrel.
2. Controllare eventuali ostruzioni: Verify that the high-pressure tube and the gun barrel are not obstructed.
3. Turn Off Gun Head Switch: Ensure the switch on the gun head is turned off.
4. Observe Pressure Gauge and Start: Observe the pressure gauge value. Press the start switch to begin the test.
5. Check for Low Pressure Stop: Confirm if the machine stops when the pressure is low (the manometer should stop around 500 kg/cm²).
6. Pressione di rilascio: Open the gun head to release any remaining pressure.

5. Istruzioni per l'uso

Follow these steps for effective grouting operation:

1. Preparare la superficie: Clean the base surface thoroughly and identify the exact leak point. Drill holes at approximately 45-degree angles, 2-8 cm on both sides of the crack or leak point.
2. Insert Water-Stop Needle: Insert the black rubber part of the water-stop needle into the drilled hole. Use tools such as a T-shaped wrench to lock and fix the needle securely in place.
3. Load Slurry and Connect Power: Install the grouting slurry into the material barrel. Plug the machine into a suitable power supply. Fasten the machine gun head and the water-stop needle head together.
4. Start Perfusion and Monitor Pressure: Turn on the switch located on the handle to begin the perfusion process. Continuously pay attention to the pressure value displayed on the machine's pressure gauge. It is critical that the pressure does not exceed the yellow scale area on the gauge.
5. Stop Grouting: Continue grouting until the grout visibly overflows from the crack, indicating complete filling. Then, turn off the machine.
6. Remove Needle and Finish: After at least 48 hours, carefully remove the water-stop needle. Finally, fill and finish the base surface to complete the repair.

6. Manutenzione

Regular maintenance ensures the longevity and optimal performance of your grouting machine.

• Pulizia dopo l'uso: After each use, thoroughly clean the material barrel, high-pressure pipe, and nozzle to prevent material hardening and blockages. Use appropriate cleaning agents recommended for your specific grouting material.
• Pump Core Inspection: Periodically inspect the stainless steel alloy pump core for any signs of wear or damage. Ensure it remains free of debris.
• Integrità del sigillo: Check all seals and connections for leaks. Replace any worn or damaged seals promptly to maintain pressure and prevent material leakage.
• Ventilazione del motore: Keep the ventilation holes on the electric drill clean and unobstructed to ensure proper heat dissipation and prevent overheating.
• Magazzinaggio: Store the machine in a clean, dry place, away from extreme temperatures and direct sunlight. Ensure all components are dry before storage.
• Lubrificazione: Refer to the specific grouting material's guidelines for any lubrication requirements for the machine's moving parts, if applicable.
