This equipment is a core component of the underground gob-side entry retaining system. The coal mine concrete pump is specifically designed for concrete transportation in underground coal mines, suitable for high-pressure, long-distance material conveyance in such environments.
Multi-purpose Ultra-high pressure Long-distance transport High reliability High safety
● Ultra-high Pressure and Long-distance Transport with Adjustable Pumping Capacity:
The maximum outlet pressure is 21 MPa, with a maximum transport distance of 8 km. The hydraulic pump displacement utilizes electric proportional variable control technology, enabling remote and stepless adjustment.
● Stable Output with Minimal Switching Shock:
Featuring an open hydraulic system and multi-pump converging hydraulic system with constant power control.The main cylinder's direction change is controlled by an electric proportional slope reduction method,minimizing switching shock and reducing failure rates.The swing valve cylinder is equipped with an adjustable buffer valve group to reduce impact during direction changes.
● High Reliability:
Two sets of power units act as backups for each other,capable of working simultaneously or independently.Critical electrical and hydraulic components are imported.Wear parts are made from special materials and are specially designed for long service life.
● High Suction Efficiency:
The large-mouth S-valve design increases suction area, improving suction efficiency.
● High Efficiency and Energy Saving:
The hydraulic pump displacement uses electric proportional variable control technology to output as needed, enhancing efficiency and energy savings.
● Easy Maintenance:
Maintenance and operation points are easily accessible; the open layout provides more space for maintenance, and specialized tools are available for specific parts.
● Cost-effective Operation:
Automatic variable displacement technology ensures output as needed;high-quality hydraulic pump and valve group systems;long-life wear parts(wear plates,cutting rings,pistons,S-pipes,etc.)result in low operational and maintenance costs.
● Built-in Mixing Device:
The pump hopper is equipped with a mixing device to improve slurry flow and enhance pump suction efficiency.
● Long Service Life:
The use of top domestic and international brand hydraulic pumps and valve group systems ensures reliable quality.The flow parts are made of special materials and processes(wear plates,cutting rings,pistons,S-pipes,etc.),ensuring long overall machine life.
