motor driven concrete pump
The motor driven concrete pump is a device that uses an electric motor as a power source to deliver concrete to the construction site through a pumping system. It is widely used in various projects such as buildings, bridges, roads, tunnels, etc., and is one of the indispensable machines in modern construction. The motor-driven design makes it have lower energy consumption, higher stability and more environmental protection compared to diesel or gasoline-driven pumps.

Product Structure
The motor-driven concrete pump is mainly composed of the following parts:
Motor: As the driving source, a three-phase AC motor or DC motor is usually used to provide power to drive the pumping system.
Pumping system:
Hopper: used to receive the mixed concrete.
Piston or screw pump: Depending on the model, the concrete pump can use either a piston or screw pump. The piston pump uses the reciprocating motion of the piston to achieve the suction and delivery of concrete, while the screw pump uses the rotation of the screw to achieve the medium delivery.
Piping system: Pipes used to transport concrete from the pumping system to the construction site, usually made of wear-resistant materials.
Control system: used for automatic control of the motor and pumping system, including start, stop, flow regulation and other functions.
Cooling and lubrication system: Provides necessary heat dissipation and lubrication for the motor to ensure the normal operation of the equipment under high load conditions.
Working principle
The mixed concrete enters the pumping system through the hopper. When the motor is started, the motor drives the piston or screw to rotate through the reducer. For piston pumps, when the piston moves backward, the concrete is sucked into the pump tank under negative pressure. When the piston moves forward, the concrete is compressed and sent out through the pipe. For screw pumps, the concrete is continuously pushed forward by the rotation of the screw. The concrete is transported to the location where construction is required through the piping system. By adjusting the valve, the flow rate and pressure of the delivered concrete can be controlled.
Product Advantages
High efficiency: The output power of the motor is stable and can continuously provide efficient power to ensure the rapid operation and high production efficiency of the concrete pump.
Low noise: Compared with diesel or gasoline driven concrete pumps, motor-driven concrete pumps have less noise and are suitable for cities or noise-sensitive environments.
Environmental protection: Motor drive does not produce exhaust gas, meets modern environmental protection requirements, and reduces the impact on the surrounding environment.
Easy maintenance: The components of motor-driven equipment are relatively simple and easy to maintain.
High operational safety: Motor-driven concrete pumps are usually equipped with a variety of safety protection devices, such as overload protection, short-circuit protection, etc., to ensure the safety of the equipment.
Strong adaptability: Electric concrete pumps can be widely used in various construction projects and have good adaptability to meet the needs of different working conditions and construction.
