How to operate a high pressure grout pump?

High-pressure grouting pump is a machine used for high-pressure chemical grouting of structures, using single-liquid or double-liquid chemical grouting materials or cement materials. How to operate the high pressure cement grouting machine? This may be a problem that many beginners, operators, builders or workers need to face. You can refer to the following steps to realize the operation of most high-pressure grouting pump. Welcome to view the best safe operation procedures for high-pressure grouting machines.

A high-pressure grouting pump is mainly composed of electric drill, chassis, bracket, material cup, pump, tee, pressure gauge, high-pressure pipe and switch valve group. The body is compact, easy to carry and move, and can be operated by a single person. The electric grouting pump solves the inconvenience of relying on the traditional hand-pressed air source as power and carrying heavy machinery; the structure design is scientific and simple, and it can be maintained without special training, and a humanized self-priming feeding system is newly added. Using mechanical power, it can increase the working pressure to over 4500psi (300kg/cm2) within 3-6 seconds, and can effectively pour the liquid water-stopping agent into the tiny cracks of 0.1mm, and the construction efficiency is three times faster than the traditional technology and the waterproof and anti-leakage effect is more durable and effective. It is the best equipment for construction engineering, underground engineering, water conservancy engineering, environmental protection engineering, municipal, subway, tunnel, culvert engineering, seepage stoppage construction, crack reinforcement, and is the choice of waterstop constructors.

Operation steps of high pressure electric grouting pump

1. Check whether the power supply of the high-pressure cement grouting pump is normal.
2. Check the motor and gear oil pump, and turn it a few times.
3. Turn on the switch of the pressure gauge and loosen the pressure regulating handwheel of the overflow valve.
4. Put the suction pipe into clean water to test.
5. Check whether the steering of the motor and gear oil pump is correct.
6. Check whether the hydraulic reversing valve group can control the reciprocating movement of the oil cylinder.
7. Start the motor, adjust the system pressure to 1-2Mpa, and run the test for about 5 minutes (at this time, the discharge valve of the mixer is fully opened). If it is functioning properly, close the valve on the mixer and adjust the oil pressure to the desired level. Maximum pressure, then stop the grouting machine, ready to work.
8. Open the grouting valve of the mixer and inject water for 1 minute. If everything is normal, quickly put the two suction pipes into the grout tank for normal grouting operations.

Features of Electric High Pressure Grouting Pump

1. Environmental protection: good mechanical performance, no noise.
2. Portable: small size, light weight, easy to carry and operate.
3. Efficient: It can reach 0—50Mpa working pressure in a few seconds, which saves time and effort.
4. Safety: Reliable technology, reasonable structure and safe use.
5. Sustained pressure: Sustained high pressure enables the agent to effectively fill and block the micro-gaps, micro-slits, micro-pores and capillaries in the concrete structure.
6. No damage to the structure: directly install the grouting nozzle on the cracks of the concrete for grouting, without picking grooves or burying pipes, and there is no damage to the structure.
7. Leakage plugging with water: It can directly carry water and grout for plugging of leaks in various gaps, honeycomb leaks, and underground water gushing. The slurry can be effectively injected deep into the fracture.
8. Range of supporting materials: Polyurethane, epoxy resin, acrylic resin and other non-granular low-viscosity slurry materials can be used.
9. Multi-function: one machine with multiple functions such as plugging grouting, consolidation grouting, crack reinforcement grouting.
10. Durable: parts are durable when the pressure is 50Mpa. Easy to maintain, easy to repair, sturdy and easy to clean.

Application range of electric high pressure grouting pump

1. Plugging and sealing of cracks, expansion joints, construction joints and structural joints in various buildings and underground concrete works.
2. Leakage plugging and reinforcement of drilling retaining wall in geological drilling engineering.
3. Grouting of reservoir dams in water conservancy and hydropower projects, plugging and anti-seepage of cracks in water delivery tunnels, seepage prevention and reinforcement of concrete cracks in dam bodies.
4. Subway, tunnels, culverts, sewage treatment pools, and concrete cracks leak water, and plugging with water.
5. Water leaks from basement, underground garage, underground passage, and concrete cracks, and plugging with water.
6. Roof concrete slab cracks, wall pipes, wall corners, water leakage, plugging with water.
7. High pressure epoxy resin injection for cracks in concrete structures, beams, columns, and slabs.
