Home > Main Business > Complete Set of Coal Mine Backfill System
This equipment is a core component of the paste backfill pumping system, widely used in coal mine paste backfill, tailings backfill in both metal and non-metal mines, high-concentration tailings discharge, wastewater treatment in the metallurgical and petrochemical industries, and solid waste treatment. It provides a safe and reliable solution for long-distance transportation of complex high-solid-content, viscous materials. The maximum outlet pressure reaches 21 MPa, and the maximum conveying capacity is 500 m³/h.
Multi-domain large volume long-distance transport High reliability high safety
● Large Volume, Long-distance Transport (Maximum Conveying Capacity of 500 m³/h):
Utilizes a multi-pump converging hydraulic system with constant power control,offering powerful yet non-overloaded performance.The system features proprietary large-diameter spool valve parallel synchronous control hydraulic technology,successfully resolving the switching challenges in ultra-large flow hydraulic systems.
● Stable Output with Minimal Switching Shock:
The system incorporates proprietary switching logic technology to further reduce hydraulic switching shock, ensuring stable output with virtually no impact during hydraulic switching.
● High Reliability:
Fully electrically controlled switching technology and imported hydraulic components are employed.The dual-power hydraulic station operates in parallel,independently,and acts as a backup for each other.
● High Suction Efficiency:
Equipped with a dual mixing and feeding mechanism and large-outlet S-valve design,increasing suction area and enhancing suction efficiency.
● Central Integrated Control:
Features real-time operation monitoring,fault diagnosis,and overload protection functions,offering various communication interface options for quick integration with upper-level equipment.
● Extended Service Life of whole machine:
All critical core components are made from highly reliable brands, ensuring an overall machine service life of more than 20 years.
● High Efficiency and Energy Saving:
The system employs variable energy-saving technology with electric proportional control, delivering powerful performance while ensuring efficient and energy-saving output.
● Long Service Life of components:
Wear parts such as wear plates,cutting rings,and S-pipes are made from fully hard alloy rings with special welding processes for high wear resistance.The inner walls of the conveying cylinders are coated with multiple layers of hard chrome,providing superior wear resistance and extended service life.
● High Safety Performance:
The system provides monitoring of the operating status of each component, with timely fault diagnosis, alarms, and interlock shutdown controls.
● Cost-effective Operation:
Critical lubrication points feature synchronized lubrication and central lubrication systems,resulting in low grease consumption.The automatic variable displacement technology outputs as needed.High-life wear parts(S-pipe,wear plates,cutting rings,pistons,etc.)contribute to low operational and maintenance costs.
● Easy Maintenance:
The system features full-time monitoring of operating status,providing real-time fault feedback and maintenance reminders.It also offers intelligent fault self-diagnosis and remote fault diagnosis capabilities,allowing for pre-diagnosis of faults.The main cylinder is equipped with a jogging function,facilitating quick and easy replacement of the conveying piston.The equipment can be operated locally or remotely,with easy switching between modes.
● High level of ergonomics:
Key operation points provide guidance and instructions,enabling on-site personnel to quickly familiarize themselves with the equipment.Multiple emergency stop devices are installed throughout the equipment,allowing for a rapid pump shutdown in the event of an accident to prevent further escalation.
