Diesel Engine Concrete Pump

Diesel engine concrete pump is a concrete conveying equipment with diesel engine as power source, which is widely used in construction, mining, tunnel, water conservancy engineering and other fields.

1. Working principle

The core of diesel engine concrete pump is hydraulic transmission system, and its working principle is as follows:

- Power source: Diesel engine drives hydraulic pump to generate high-pressure hydraulic oil.

- Hydraulic system: Hydraulic oil drives piston movement through cylinder, sucks concrete from hopper and presses it into conveying pipe.

- Distribution valve control: Control the flow direction of concrete through S valve or other forms of distribution valve to ensure continuous pumping.

- Output adjustment: According to the pumping pressure and load changes, the diesel engine speed can be automatically adjusted to maintain the best working condition.

2. Main models and parameters

According to the knowledge base information, the following are some typical models and their parameters):

Model: HBTS40/HBTS50 trailer concrete pump

Power range: 22-165 kW

Transportation capacity: 10-90 m³/h

Core features:

The hydraulic system is efficient and stable, and fuel consumption is saved by 15%

Using international brand components (such as Bosch Rexroth hydraulic system)

Adapting to complex working conditions (such as underground coal mines and mountain construction)

3. Performance advantages of diesel engine concrete pump

- Strong adaptability:

No electricity environment: Diesel engine power can meet the needs of field and power-deficient construction sites.

Complex terrain: such as mines, tunnels, and hilly areas, the equipment can be flexibly moved.

- Energy-saving:

Adopting intelligent control system, automatically adjusting speed and pressure to reduce fuel consumption.

HBTS40 model saves 15% of comprehensive fuel consumption and increases power by 5%.

- Durability:

Core components (such as cylinders and distribution valves) are made of high-strength materials to extend service life.

The explosion-proof design is suitable for special environments such as coal mines.

- Versatility:

Supports multi-purpose operations such as pumping and wet spraying to meet the needs of mine construction, tunnels, and water conservancy projects.

Optional insulation/heating function to adapt to construction in low temperature environments.

4. Application scenarios of diesel concrete pump:

- Construction:

Concrete pouring of high-rise buildings, bridges, and tunnels.

High-pressure pumping to high altitudes (such as 50-80 meters vertical height).

- Mining engineering:

Mine support, tunnel closure, and shaft construction.

Applicable to underground coal mines (explosion-proof type) and open-pit mines.

- Water conservancy projects:

Construction of large infrastructure such as water diversion tunnels, dams, and reservoirs.

- Special working conditions:

Concrete transportation of large aggregates (maximum particle size 50 mm).

Narrow space operations (such as tunnels and mountain construction).

5. Technology trends:

- Intelligent: Equipped with a car networking system to monitor the status of the equipment in real time.

- Environmental protection: National V emission standard diesel engines have become mainstream.

- Energy-saving design: low fuel consumption and long endurance.

6. Purchase suggestions

Focus on core configuration:

- Hydraulic system stability (such as Bosch Rexroth hydraulic pump).

- Diesel engine power and fuel consumption performance (such as Yunnei and Weichai brands).

- Aggregate particle size limit (whether it meets engineering requirements).

7. Industry prospects

- Technical direction: Develop in the direction of intelligence, energy saving and environmental protection, and new energy (such as electric + diesel hybrid) may become a future trend.

- Export potential: Southeast Asia, the Middle East, Africa and other regions with strong infrastructure demand are the main export markets.
