How does a concrete pump truck work?

In construction, concrete is an indispensable material. In order to efficiently transport concrete to the construction site, the concrete pump truck has become one of the key equipment in the construction process.
Smat machine has more than 20 years of experience in concrete pump production, so how does concrete pump truck work? Smat will introduce the working process of concrete pump truck in detail in this article to help users understand the use and operation points of this equipment more comprehensively.

Understand the working principle of concrete pumps

If we want to know how concrete pump works, we need to understand the working principle of concrete pumps first.

The magic of concrete pumps is that they can use the pressure generated by the hydraulic system to suck and push concrete to the designated position through the reciprocating motion of the piston or plunger.

Concrete pumps use hydraulic power to push concrete to flow in the pipeline throughout the process to achieve long-distance or high-altitude transportation.

Specifically, the hydraulic system drives the piston or plunger to reciprocate in the delivery cylinder.

When the piston or plunger moves backward, negative pressure is generated to suck the concrete into the delivery cylinder;

When the piston or plunger moves forward, the concrete is pushed out of the delivery cylinder and sent into the pipeline.

The distribution valve is responsible for controlling the suction and discharge direction of the concrete to ensure that the concrete can flow smoothly between the delivery cylinder and the pipeline.

After understanding the operating principle of concrete pumps, we can better understand how does a concrete boom pump work. We can also understand the working process of concrete more clearly.

How to operate a concrete pump?

If you are an operator or a builder, you will definitely want to know how to use a concrete pump. After understanding the working principle and method of a concrete pump, we only need to follow the following steps to operate the concrete pump.

1. Preparation work

Before using the concrete pump truck, a series of preparation work needs to be done. Make sure that there are no obstacles in the working area of ​​the concrete pump truck so that the operation can be carried out smoothly. Check whether the relevant parts of the concrete pump truck, such as the pumping pipeline and hydraulic system, are operating normally to ensure the safety and reliability of the equipment. Also prepare enough concrete raw materials and transport them to the storage area near the pump truck.

2. Set up the pumping pipeline

During the working process of the concrete pump truck, the setting of the pumping pipeline is very critical. Connect the feed port of the pumping pipeline with the concrete in the storage area, and ensure that the connection is tight to avoid concrete leakage. According to the needs of the construction site, connect the pumping pipeline section by section and fix it with a special clamp to ensure safety and reliability. When setting up the pumping pipeline, you also need to pay attention to the degree of curvature and slope of the pipeline to ensure the smooth delivery and uniform distribution of concrete.

3. Start the concrete pump truck

After the preparation work and the setting of the pumping pipeline are completed, the concrete pump truck can be started for formal work. Turn on the power switch of the concrete pump truck and check the working status of the hydraulic system. Open the vent valve on the concrete delivery pipeline to remove the air in it to ensure the continuous delivery of concrete. Next, deliver the concrete from the mixer truck or storage area to the feed port of the pumping pipeline and observe the flow of concrete. After the concrete begins to flow out of the pump truck pipeline, the vent valve can be closed and the delivery power of the concrete pump truck can be gradually increased.

4. Pumping concrete

Once the concrete pump truck is in normal working condition, it can start pumping concrete to the construction site. During the pumping process, the flow and stability of the concrete should be maintained. If the concrete flows poorly or is blocked, the pumping should be stopped immediately and the pipeline should be checked for foreign matter or blockage. It is also necessary to control the pumping speed and pressure of the concrete to avoid damage to the construction site.

5. Cleaning and stopping work

After completing the concrete pumping task, the equipment should be cleaned and stopped. The delivery system of the concrete pump truck should be turned off and the connection with the pumping pipeline should be disconnected. Empty the concrete in the pumping pipeline and rinse it with clean water to prevent the concrete from solidifying in the pipeline. Carefully clean the various parts of the concrete pump truck, and inspect and maintain the equipment to ensure safety and reliability when it is used next time.

Through the above work flow and operating precautions, when using concrete pump trucks for construction, tasks can be completed efficiently and safely. The use of concrete pump trucks not only improves construction efficiency, but also ensures the quality and uniformity of concrete, providing solid support for the smooth progress of construction projects
