How Does A Concrete Pump Work

How Does A Concrete Pump Work

A concrete pump is a tool mainly used for conveying freshly mixed concrete to the location on a construction site where it is needed to be placed. It works using a valve system and the basic fundamental of hydraulics.

Step:1

• The pumping operation starts with the discharge of the concrete, usually from a ready-mix truck that mixes concrete mix within its rotating drum.

• Step:2

• Then the truck pours the fresh concrete into a hopper, which is continuously rotating so concrete will not solidify. In the hopper of the pump, an agitator maintains the fresh concrete flowing smoothly into the pumping cylinders.

• Step:3

• From there, the concrete pump sucks the liquid concrete mix out of the hopper, through a valve system, and into the area where it needs to be laid down. Sometimes with the use of auxiliary hoses.

• Step:4

• Pistons of concrete pumps utilize the same principle as a twin-cylinder work with the reciprocating engine, in which the one cylinder draws concrete from the hopper on the return stroke and another cylinder pushes mix on the forward stroke into the pipeline.
• A twin-cylinder hydraulic pump’s internal workings typically consist of two parallel cylinders. The cylinders have driven pistons inside them that move them backward and forward in opposite directions. As the first cylinder moves forward, the second one moves back.

• Step:5

• Pistons in both cylinders operate in inverse directions so there is constant pressure applied on the concrete mix in the pipeline and uninterrupted flow. The pistons in the concrete pump are operated by hydraulic cylinders powered by a hydraulic pump.
• A synchronized valve permits concrete from the two cylinders to go into one pump discharge line. This valve is frequently used to differentiate one type of pump from another.
• The 1st cylinder, also known as the material cylinder, pulls concrete out of the hopper. The 2nd cylinder known as the discharge cylinder thrust the concrete out of the pump in the location where it is needed to be placed on the site.
• Step:6
• The two working pistons, alternately pulling in and pushing out their volumes of liquid concrete. The hydraulic flow created by the continuous flow of concrete is important to prohibit the liquid concrete from solidifying.
