With the rise of modern industry, the construction method based on concrete has become one of the main structures of the construction industry, and it occupies a large proportion in various engineering construction, making the development of concrete machinery enduring and increasingly fierce. Concrete trailer pump is a kind of concrete machinery, which is widely used in the transportation and pouring of concrete construction.

What is concrete trailer pump?

Concrete trailer pump (also known as trailer concrete pump or ground pump) is a kind of equipment used for transportation and pouring in concrete construction. Concrete Towing Pump is a mobile pumping equipment driven by hydraulics, which is specially used to transport high-viscosity fluids such as concrete and mortar.

Concrete trailer pump relies on pressure to continuously transport concrete horizontally and vertically along the pipeline through pipelines. Concrete pump trailer continuously and efficiently transports concrete to the construction area (such as high-rise buildings, bridges, tunnels, etc.) through pipelines without relying on vehicle transportation. It is an indispensable key equipment in modern construction.

How to define concrete trailer pump?

Concrete trailer pump is a concrete transportation equipment installed on a wheeled frame and can be towed to different construction sites. Trailer concrete pumps do not have their own distribution booms, so manual laying of the delivery pipeline is required.

Concrete pump trailer types

What are the two types of concrete pump trailers? There are two common types of concrete trailer pump installation power device classification, one is diesel concrete trailer pump, the other is electric concrete trailer pump, both trailer pump concrete have their own usage scenarios and characteristics.

Diesel concrete pump trailer

What is a diesel concrete pump trailer? A diesel concrete pump trailer is a mobile pumping equipment powered by a diesel engine, which is specially used to transport high-viscosity fluids such as concrete and mortar.

The diesel concrete pump trailer drives the hydraulic system through a diesel engine to control the pumping unit to continuously transport the concrete produced by the mixing station to the construction area through a pipeline. It is suitable for scenes such as the field and large infrastructure construction sites without a stable power supply. It is one of the core equipment in traditional infrastructure projects.

The diesel concrete pump trailer is characterized by strong power, strong adaptability, independent operation, and no need for an external power supply, but there are problems such as high noise and exhaust emissions.

How does a diesel concrete pump work?

The diesel engine drives the hydraulic pump through a belt or gear drive, and the hydraulic pump pressurizes the hydraulic oil. The power transmission process is diesel engine → hydraulic pump → hydraulic motor/cylinder → pumping mechanism.

1. Hydraulic system: The pressurized hydraulic oil enters the hydraulic cylinder through the hydraulic pipeline, drives the piston to reciprocate, and completes the suction and discharge of concrete.
2. Pumping cycle:

3. The role of the distribution valve: The distribution valve (such as S-shaped valve, gate valve, etc.) is used to control the flow direction of concrete to ensure that the concrete is evenly distributed during the transportation process.

4. Cyclic action: The hydraulic system controls the reversal of the cylinder through the solenoid valve and the stroke switch, so that the two hydraulic cylinders alternately perform suction and feeding actions, thereby achieving continuous pumping.

Electric concrete pump trailer

What is an electric concrete pump trailer? An electric concrete pump trailer is a type of equipment that uses an electric motor as a power source. Unlike traditional diesel-powered pump trailers, it is powered by an electric motor (or battery pack) and combines a hydraulic system to control the pumping unit to continuously transport the concrete produced by the mixing plant to the construction area through a pipeline.

The electric concrete pump trailer drives components such as pistons or screws through a hydraulic system to suck concrete from the hopper and push it to the construction equipment at the designated location. Electric concrete pump trailers are usually installed on trailers with wheels to facilitate movement and transfer at the construction site.

The core features of electric concrete pump trailers are environmental protection, low noise, and high energy efficiency. They are suitable for construction scenarios that are sensitive to emissions and noise (such as urban buildings and indoor projects).

How does an electric concrete pump work?

The working principle of an electric concrete pump is based on a hydraulic system.

1. Hydraulic system drive: The motor pressurizes the hydraulic oil through the hydraulic pump to drive the piston in the hydraulic cylinder to reciprocate.

2. Concrete suction and delivery: When the piston of a hydraulic cylinder retracts, the concrete in the hopper is sucked into the delivery cylinder under the help of atmospheric pressure and the stirring blades; the piston of the other hydraulic cylinder extends to push the concrete in the delivery cylinder out through the pipeline.

3. Cyclic action: The hydraulic system controls the reversing of the oil cylinder through the solenoid valve and the stroke switch, so that the two hydraulic cylinders alternately perform suction and delivery actions, thereby achieving continuous pumping.

4. The role of the distribution valve: The distribution valve (such as S-shaped valve, gate valve, etc.) is used to control the flow direction of concrete to ensure that the concrete is evenly distributed during the delivery process

Trailer pump concrete structure

Core components of trailer concrete pump

Power system

Usually driven by diesel engine or electric motor, it provides the power required for high-pressure pumping. Some high-end models are equipped with intelligent control system, which can monitor parameters such as pressure and flow in real time.

Pumping unit

Main cylinder driven by hydraulic pressure to drive concrete suction and discharge.

S-valve:

controls the flow direction of concrete, realizes efficient switching and anti-blocking function.

Spectacle plate and cutting ring:

reduces concrete backflow and prolongs the life of pump pipe.

Hydraulic system:

uses plunger pump or gear pump to convert mechanical energy into hydraulic energy to drive pumping mechanism.

Chassis and mobile device

Trailer design, can be moved by tractor, adapt to different construction site scenes. Some models are equipped with self-propelled function (such as vehicle-mounted pump).

Control system

Manual or automatic operation interface, supports pressure regulation, fault diagnosis and other functions.
