Grouting machine, simply defined as a kind of mechanical equipment for pressure conveying and perfusion of flowable slurry.There are many types of grouting machines, which can be classified according to their purpose, according to their working principle, according to the size of the pressing force, and can also be classified according to the thickness of the pumped slurry and the thickness of the aggregates contained.In short, each different grouting machine was developed at the beginning of the period and was based on a specific purpose. There is no pump with equipment that can meet all construction conditions. It is just that with the delay of time and continuous improvement in use, some grouting machines are more powerful, but they are far from reaching a grouting machine with equipment that is all over the world and violates basic science.In this regard, we must have a clear mind and rigorous scientific understanding.
1. Manual grouting machine, with low pressure, it can be said that there is almost no pressure. It is purely manual operation to squeeze the slurry out of the slurry. It is commonly used in various waterproof repair grouting. The grouting machine is very cheap and the structure is very simple.
2. Waterproof high-pressure grouting machine, with a pressure of less than 1MPa, is mainly used for grouting of thin slurry materials with waterproof, particle-free fluidity. The pressure of the grouting machine is not large, but in the waterproof industry, everyone is used to it, so it is called a high-pressure grouting machine or a high-pressure grouting machine, nothing more. The price is about 1,000 yuan. This kind of small grouting machine is very practical and very lightweight for individuals who are simply engaged in repairing grouting.
3. Extrusion grouting machine, known as extrusion pump or mud pump in the industry, is mainly used for short-distance perfusion of thin pure grout, which cannot be mixed with any material with aggregate particles. The grouting machine has a very small pressure, mainly relying on intermittent weak pulse pressure generated by the cam squeezing hose to squeeze the grout out, to achieve the purpose of short delivery of cement slurry, the use is extremely limited, and the grouting efficiency is slow and low.Most of the prices are around 3,000 yuan. Most of them are used by small contractors and individuals who are just starting out in some small grouting projects. The late maintenance of the mud pump is mainly due to the rapid wear of the mechanical seal and hose, and the blocked pipe is not easy to clear.
4. Single-cylinder piston grouting machine, a kind of cheap grouting equipment that relies on the cylinder liner piston to generate pressure. The principle is self-evident. It is a stroke of the piston that generates a pressure, which in turn promotes the flow of thin slurry. Since the piston pressure is discontinuous, there are pulses and the pressure is intermittent. This determines that this type of grouting machine can only pump very thin grout, and a slightly thicker pure grout will cause serious pipe blocking consequences. Of course, it is definitely not possible to add sand. If the sand is added very little, such as cement: Sand is at 2:1. The above is a different matter, but the so-called “sand pulp or mortar”, which is mostly cement and has very little sand, is a bit reluctant, and it is a bit suspected of selling dog meat. After all, this is not called sand pulp at all.However, the pump is not expensive, it is only a little bit more expensive than the extrusion pump, but the grouting efficiency is low, the pressure is small and there is a pulse, and it will lie down when it encounters a slightly thicker slurry.Users use it with caution!Of course, if Party A has no special requirements or the supervision and management are not strict, it can be said that the grouting project that can pass the customs by pouring grout as thin as rice soup can also be used. The pump has a certain self-priming capacity and has a slurry inlet pipe and a slurry outlet pipe.
