SL-605 Electric High-Pressure Infusion Machine
产品详情
Water leakage is a common issue in building structures. With today’s technology, construction methods and material selections are diverse and each has its merits. Therefore, choosing the right technology and materials for the right structure, location and condition has become a key topic in professional waterproofing.
Water leakage often occurs in cracks and honeycombs of tunnels, diaphragm walls and other structures. Various technologies have been widely used for structural leakage stoppage. However, when dealing with negative-side water penetration, traditional methods are still commonly used: chiseling at seepage points and then applying or filling with negative-side waterproofing materials.
Such methods often lead to secondary, tertiary or even repeated leakages, achieving only superficial or partial sealing instead of deep filling and thorough water stopping. The reason is that groundwater flowing from the outside of tunnels or structures through cracks, joints or honeycombs cannot be completely stopped unless blocked fundamentally.
Therefore, high-pressure injection grouting technology has been adopted internationally for its excellent performance, and is widely accepted by civil engineering, construction professionals and project owners. It is applied in metro projects, bathrooms, tunnels, basements, and even in general buildings and residential leakage repair.
Features
SL Shenglong high-pressure injection machine is developed and precisely designed in cooperation with renowned foreign machinery manufacturers, focusing on practical and user-friendly operation.
Made of special tough and wear-resistant materials, it is durable, lightweight and portable, overcoming the disadvantages of common small injection machines such as high failure rate, difficult maintenance and frequent malfunctions.
Designed for quick assembly, disassembly and easy maintenance, this professional equipment is used for structural grouting, water stopping and crack reinforcement.
It provides ultra-high working pressure without deformation of components during high-pressure grouting. Lightweight and portable, it is an ideal tool for professional waterproofing and crack reinforcement.
Fast Construction
Reaches a working pressure of 15,000 psi within 10 seconds, with higher grouting efficiency than other equipment.
Lightweight
Net weight: 9 kg, easy to carry and move.
Continuous Pressure Boosting
Injects PU waterstop grout into micro-cracks larger than 0.01 mm, sealing leakages accurately and effectively.
Application Scope
Leakage stopping and reinforcement for concrete structures:basements, floor slabs, construction joints, metros, tunnels, dams, diaphragm walls, honeycombs, voids, expansion joints, segments, post-pouring belts, etc.Also applicable for foundation, floor and harbor engineering reinforcement.
Operating Instructions
- 1.Connect the power supply and ensure the grouting machine is switched off.
- 2.Before using a new machine, pour engine oil into the material cup, turn on the power to circulate and discharge the oil.
- 3.Wipe the machine body and accessories with a soft cloth dipped in lubricating oil.
- 4.Pour single-component PU waterstop directly into the material cup (two-component epoxy resin must be evenly stirred before pouring). Close the cup lid tightly.
- 5.Set the injection valve to OPEN. Aim the injection gun at a waste bin, turn on the power and pump out residual oil until grout flows out.
- 6.Firmly attach the injection gun to the injection needle. Open the injection valve first, then start the power switch. Inject grout under continuous pressure until it overflows from surrounding surfaces.Turn off the power, then close the injection valve. Loosen the valve and remove the gun.
- 7.Immediately after construction, pour special cleaning agent (xylene, turpentine, acetone, etc.) into the material cup. Pump out residual grout until cleaning agent flows out.Insert the injection valve into the cup and operate repeatedly to create 200 kg pressure inside the pipeline for thorough cleaning.After cleaning for 3–5 minutes, discharge the cleaning agent. Then circulate engine oil for maintenance and keep oil inside the machine to prevent clogging caused by residual grout.Note: Keep the cup lid tightly closed.
Note: Two-component materials must be used within their usable life. Please refer to the material instruction manual to avoid hardening and clogging in the cup or pressure pump.
Precautions
- Check all screws for looseness.
- Tighten the nuts at both ends of the high-pressure hose to prevent grout ejection during injection.
- The booster pump and pressure pump are equipped with a 17-size hexagonal copper nut and a thickened Teflon gasket for anti-leakage.If heavy leakage occurs during operation, tighten the copper nut properly.
- The maximum instantaneous pressure of this machine is 10,000 psi. Always consider the pressure resistance of injection needles and hoses of other brands to reduce risks.
- Wear protective equipment (gloves, mask, goggles) during operation to avoid direct skin contact.If splashed onto skin, rinse immediately with water. If contact with eyes occurs, flush with plenty of water and seek medical attention immediately.
- Do not pour particles into the material cup to avoid scratching the pressure pump.
- Clean the machine immediately with cleaning agent after use, then circulate engine oil for maintenance.
Troubleshooting
Leakage at the injection gun during operation
Cause: Worn internal gasket.Solution: Disassemble the gun, replace the rubber gasket and four claws, then reassemble.
Machine fails to build pressure
Solution 1: Remove the hexagonal screw of the booster pump. Clean the groove of the pressure pump, steel ball, spring and booster pump with a soft brush and cleaning agent.Replace the steel ball if its surface is not smooth, then reassemble and test.
Solution 2: If heavy leakage persists after tightening the copper nut, replace the anti-leakage gasket:remove the four hexagonal screws on the booster pump, take out the pump, remove the copper nut, carefully dig out the old gasket, install a new one, and tighten the nut properly.
Solution 3: Replace the impact rod or a set of pressure pumps, then test the pressure.
No grout discharged from the machine
Cause: Blockage at the bottom of the material cup.
Solution: Empty the cup and remove the blockage.
Machine does not run when powered on
Cause 1: Slurry hardened and clogged inside the gearbox.
Solution: Loosen and remove the cover plates, clean residues, replace damaged parts, then reassemble.
Cause 2: Worn drill nut, failed to engage.
Solution: Remove the drill and replace the nut.
Cause 3: Poor power connection.
Solution: Check for short circuit, repair connections or replace the drill.
★ If the machine still cannot run or be cleaned after the above repairs:Keep 2/3 of the grout inside the material cup, seal the opening, attach a needle to the injection gun, close the valve to prevent foaming and clogging, and return the machine to our company promptly for professional repair service.
