SL-808 Electric High-Pressure Infusion Machine

产品详情

Water leakage problems are often found in building structures. With today’s technology, construction methods and material selections are diverse, each with its own advantages. Therefore, selecting the right technology and materials for the right material, location, and application has become an important subject in professional waterproofing.


Water leakage is frequently observed in cracks and honeycombs of tunnels, diaphragm walls, and other structures. Various technologies are widely used for structural leak stoppage. However, when dealing with negative-side water penetration, traditional methods are commonly adopted: chiseling open the seepage points on the wall and then applying or filling with negative-side waterproofing materials.


Such methods often result in secondary, tertiary, or even quartic leakages, achieving only surface or partial water stoppage, rather than deep filling and sealing. The reason is that groundwater flowing from the outside of tunnels or structures through cracks, joints, or honeycombs cannot be fundamentally blocked, making complete water stoppage impossible.

For this reason, the high-pressure injection water-stopping technology has been adopted internationally, delivering excellent results and widely accepted by civil engineering, construction professionals, and owners for major projects, including metro systems, bathrooms, tunnels, basements, and even general buildings and residential leak repairs.

Features

The SL Shenglong brand high-pressure injection machine is developed in cooperation with foreign machinery manufacturers, featuring precise design and R&D for practical use.


Built with special tough and wear-resistant materials for durability and portability, it overcomes the shortcomings of common lightweight injection machines: 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 load pressure without component deformation during high-pressure grouting, and is lightweight and portable—making it the ideal tool for professional water stopping and crack reinforcement.

Fast Construction

Reaches a working pressure of 15,000 psi in 10 seconds, with faster grouting speed than other equipment.


Lightweight

Net weight: 9 kg, easy to carry and move.


Continuous Pressure Boosting

Injects PU water-stopping agent into micro-cracks above 0.01 mm, accurately and effectively sealing leakages.

Application Scope

Waterproofing, leakage stopping, and reinforcement of concrete structures:
basements, floor slabs, construction joints, metros, tunnels, dams, diaphragm walls, small honeycombs, voids, expansion joints, segments, post-pouring belt cracks, etc.
Effectively improves foundation, floor, and harbor engineering reinforcement.

Operating Instructions

  1. 1.Connect the power supply and ensure the grouting machine is turned off.

  2. 2.Before using a new machine, pour engine oil into the material cup, turn on the power to circulate, and discharge the oil.

  3. 3.Wipe the machine body and accessories with a soft cloth dipped in lubricating oil.

  4. 4.Pour single-component PU water-stopping agent directly into the material cup (two-component epoxy resin must be stirred evenly before pouring). Close the cup lid tightly.

  5. 5.Set the injection valve to the OPEN position. Aim the injection gun at a waste bin, turn on the power, and pump out residual oil until slurry flows out.

  6. 6.Firmly insert the injection gun onto the injection needle. Open the injection valve first, then start the power switch. Continuously inject slurry into the structure under pressure until slurry overflows from surrounding surfaces.
    Turn off the power, then close the injection valve. Loosen the valve and pull out the gun.

  7. 7.Immediately after construction, pour special cleaning agent (xylene, turpentine, acetone, etc.) into the material cup. Pump out residual slurry until cleaning agent flows out.
    Insert the injection valve into the cup and switch it repeatedly to create 200 kg pressure inside the pipe for thorough cleaning.
    After cleaning for 3–5 minutes, spray out the cleaning agent. Then circulate engine oil for maintenance and keep oil inside to prevent slurry residue from clogging the pipeline.
    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 for loose screws on all parts.
  • Tighten the nuts at both ends of the high-pressure hose to prevent slurry ejection during injection.
  • The booster 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 other brands of injection needles and hoses to reduce risks.
  • Wear protective gear (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

Method 1: Remove the hexagonal screw of the booster. Clean the groove of the pressure pump, steel ball, spring, and booster with a soft brush and cleaning agent.
Replace the steel ball if its surface is not smooth, then reassemble and test.
Method 2: If heavy leakage persists after adjusting the copper nut, tighten it with a special wrench.
If leakage continues even at maximum tightness, replace the anti-leakage gasket:
remove the four hexagonal screws on the booster, pull out the pump, remove the copper nut, carefully dig out the old gasket with a sharp tool, install a new one, and tighten the nut properly.
Method 3: Replace the impact rod or a set of pressure pumps, then test the pressure.

No chemical discharge from the machine

Cause: Hardened 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 on both sides, 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 slurry inside the material cup, seal the opening, insert a needle into the injection gun, close the valve to prevent residual liquid from foaming and clogging, and send the machine back to our company promptly for professional repair service.
