A concrete line pump, also known as a fixed concrete delivery pump, is a mechanical device that delivers concrete continuously along a pipeline through hydraulic drive. Concrete line pumps are widely used in construction, bridges, tunnels and other projects, and are particularly suitable for medium- and short-distance, fixed-position concrete delivery. The following is the process of concrete line pump work.
1. Equipment preparation
Before starting the pumping operation, the concrete line pump needs to be fully inspected to ensure that all components (such as the hydraulic system, control system and delivery pipeline) are in good working condition. The operator should be familiar with the equipment’s operating manual and safety guidelines.
2. Connection and testing
Connect the delivery pipeline to the concrete line pump and ensure that the connection is tight to prevent leakage. Then perform a test run to check the pump’s functionality and the integrity of the pipeline connection to ensure that there are no potential problems.
3. Loading concrete
Concrete is poured into the pump’s hopper from a mixer truck or mixing plant. If necessary, water or additives can be added at this stage to adjust the consistency of the concrete.
4. Pumping process
The hydraulic system drives the piston or rotor in the pump to push the concrete out through the delivery pipeline. Operators need to monitor flow and pressure and adjust settings as needed to ensure a smooth and efficient pumping process.
5. Concrete delivery and pouring
Concrete arrives at the construction site through the delivery pipeline and is then poured according to the construction requirements. Operators need to continuously observe the entire process to ensure that the concrete is accurately placed and maintains a consistent consistency.
6. Equipment cleaning
After the pumping operation is completed, it is crucial to clean the concrete line pump to help extend the life of the equipment and ensure the quality and efficiency of concrete delivery. Cleaning methods include:
Water washing method: flush the pump body and delivery pipeline with a high-pressure water gun.
Chemical cleaning method: use a mixture of chemical cleaners and water to clean the pump body.
Mechanical cleaning method: use a mechanical cleaning head to clean the pump body
Factors affecting concrete line pump performance
Concrete consistency: Thicker concrete has poor fluidity and may affect pumping efficiency.
Delivery distance: Longer delivery distances may cause pressure drops, affecting efficiency.
Pumping speed: The faster the speed, the faster the concrete is poured, but it may cause aggregate separation.
Temperature: High temperatures may cause concrete to set faster, requiring faster pumping rates
