What is a Grout Pump?

What is a Grout Pump? A grout pump is a liquid and pasty compound for pumping, spraying, injecting and filling, designed to firmly press cement or grouting mixture into any foundation or structure requiring repair or construction middle.

Grouting pump, usually called Grout injection pump, Cement grout pump, Slurry grout pump, Chem grout pump, it includes high-pressure grouting pump, electric grouting pump, manual grouting pump, each machine has different characteristics, suitable for projects with different requirements .

The high-pressure Grout Pump has the characteristics of leak-free groove, high pressure, and can be constructed on the back of the water. Compared with the hand pump, the pressure is higher, the efficiency is higher, and the quality is better.

Grout pumps are mainly used in the construction of mines, tunnels, water conservancy, subways, buildings, bridges and other construction sites for grouting, water blocking, gap filling, and reinforcement of broken rock formations.

How many types of Grout Pumps are there?

How many types of Grout Pumps are there? According to the driving conditions of the Grout injection pump, the commonly used grouting pumps are generally divided into hydraulic grouting pumps, piston type grouting pumps, squeeze type grouting pumps, screw type grouting pumps and other categories.

Hydraulic grouting pump: hydraulic grouting pump is also called hydraulic grouting machine, hydraulic grouting pump. Hydraulic grouting pump is composed of electric motor, gear oil pump, relief valve, hydraulic reversing valve block, oil cylinder, working cylinder, mixer, oil tank, radiator, oil filter, inlet and outlet valves and electric control box and other components.

Piston type grouting pump: Piston type grouting machine is also called piston type grouting pump, piston type mortar pump.

Squeeze type grouting pump: Squeeze type grouting machine pump is called extrusion type grouting pump, extrusion type mortar pump. The extrusion grouting machine is composed of rollers, wheel frames, extrusion hoses, reset guide wheels, pump bodies, transmission devices, etc.

Screw type grouting pump: Screw type grouting pump is also called screw type grouting pump. The screw type grouting pump has compact structure, light weight and stable material flow. It is suitable for occasions where the conveying height is not large. It can also be placed on the middle floor as a relay pump to increase the conveying height.

The main function of the Grout injection pump is to fill water, block water, fill gaps, and reinforce broken rock formations in construction projects. It is suitable for grouting water plugging, filling gaps, etc. Reinforcement of broken rock formations, etc.

How do Grout injection pump work?

As we said earlier, the grouting pumps used are generally divided into hydraulic grouting pumps, piston grouting pumps, extrusion grouting pumps, and screw grouting pumps. There are differences in the working principles of different types of grouting pumps. The following are the working principles of several grouting pumps:

Hydraulic grouting pump: The hydraulic grouting machine is directly driven by the motor to the gear oil pump. The high-pressure oil output from the gear oil pump enters the hydraulic reversing valve block through the overflow valve, and the hydraulic reversing valve block controls the oil cylinder to do reciprocating motion. The working cylinders move synchronously, and because the bore and stroke of the working cylinders are the same as those of the oil cylinders, the displacement and pressure of the working cylinders are basically similar to those of the oil cylinders. There is a set of slurry suction valve and slurry discharge valve at both ends of the working cylinder, which can suck and discharge The same kind of slurry can also absorb and discharge two different kinds of slurry.

Piston type grouting pump: During the reciprocating movement of the piston of the piston type grouting machine, when the piston moves outward, the outlet check door is closed under the action of its own weight and pressure difference, and the inlet check door is opened under the action of the pressure difference , the liquid is sucked into the pump cavity. When the piston is pushed inward, the pressure in the pump chamber rises, the inlet check door is closed, and the outlet check door is opened to press the liquid into the outlet pipe.

Squeeze type grouting pump: The rotating wheel frame drives the rollers to crush the rubber tube installed on the inner wall of the pump to squeeze out and press the mortar in the tube. The extruded rubber hose is restored by its own elasticity and the reset guide wheel, so that the inside of the rubber hose is partially vacuumed and new mortar is sucked in.

Screw type grouting pump: The screw type grouting pump uses the helical rotor to rotate in the elastic stator to push the mortar to be conveyed continuously along the direction of the helical movement. The screw type grouting pump has compact structure, light weight and stable material flow. It is suitable for occasions where the conveying height is not large. It can also be placed on the middle floor as a relay pump to increase the conveying height.

How to choose a grout pump?

You can choose the appropriate cement grout pump according to the specific project type, such as performance and body shape.

What should be paid attention to when using the grout pump?

When the equipment is cleaned, the residual cement slurry should be thoroughly cleaned to prevent residual agglomeration, which will cause equipment failure in the next use. After cleaning the equipment, add butter to the grease hole to improve the service life of the internal seal of the transmission assembly.
