产品介绍

A slurry pump is a special pump specifically used to transport slurry or similar suspensions containing solid particles (such as sand, rock fragments, etc.). Its core belongs to the reciprocating positive displacement pump (mainstream type), and it also includes other types such as centrifugal pumps. It is an indispensable fluid transport equipment in industrial production.

Features

Features:

Smooth operation with minimal fluctuations Five sets of pistons move reciprocally in a staggered manner, with adjacent eccentric wheels differing by 72°, reducing pressure and flow fluctuations by 30%-40% compared to three-cylinder pumps, effectively minimizing pipeline vibrations and component wear. Powerful and capable of handling demanding conditions High-pressure models have a rated power of up to 3000 horsepower and a maximum pressure exceeding 50 MPa, meeting the high-pressure, high-displacement delivery requirements of ultra-deep wells and offshore drilling, suitable for complex geological conditions. Precise control and high automation Mainstream models are equipped with PLC control systems and variable frequency technology, allowing real-time precise adjustment of speed, displacement, and pressure, with parameter monitoring and fault alarm functions, reducing manual operation. Energy-efficient and durable, easy to maintain Power transmission efficiency exceeds 90%, with energy consumption 10%-15% lower than that of three-cylinder pumps; key components use wear-resistant materials and standardized designs, facilitating easy disassembly and maintenance, and lowering operational costs. Wide adaptability and versatile applications:Modular design can be adapted to land, marine, desert, and other environments, compatible with various drilling fluids, and flexibly suited for deep well, well maintenance, mining, and other operational scenarios.

Basic Principles and System Composition

Basic Working Principle

A five-cylinder mud pump is a positive displacement reciprocating pump, which achieves high-pressure and stable delivery of drilling fluid through the cycle of 'power transmission - piston reciprocation - slurry suction and discharge.

Overall System Composition

Power System (Power Core): The core components are AC variable frequency motors (mainstream) or hydraulic motors, paired with inverters and transformers (electric drive) or hydraulic pumps and valve assemblies (hydraulic drive). They are responsible for providing the power needed for piston reciprocating motion. Speed can be precisely controlled through variable frequency technology to accommodate different displacement requirements.

Transmission System (Power Conversion Core): Composed of crankshaft, connecting rods, crosshead, and gearbox. Its core function is to convert the rotational motion of the power source into the staggered reciprocating motion of five sets of pistons (crankshaft eccentric wheels with adjacent angles of 72°), ensuring smooth and loss-free power transmission.

Hydraulic End System (Fluid Transfer Core): Includes cylinders, pistons, suction valves, discharge valves, cylinder liners, and air chambers. Responsible for suction, compression, and discharge of drilling fluid. One-way valves (suction/discharge valves) prevent backflow of mud, and the air chamber buffers pressure fluctuations to ensure stable high-pressure delivery.

Control System (Control Core): Centered on a PLC controller, paired with a driller's control console, sensors, and display screens. It can collect operational parameters such as displacement and pressure in real-time, automatically adjust power output, achieve constant pressure and displacement control, and also features fault alarms and shutdown protection.

Lubrication System (Protection Core): Composed of a lubrication oil tank, oil pump, lubrication pipelines, and filters. It uses a combination of forced and splash lubrication to lubricate and cool the transmission system and hydraulic end moving components, preventing wear and overheating of parts and extending equipment life.

Auxiliary System (Support Core): Includes a spraying system (to cool and wash cylinder liners and pistons), an injection system (to prevent air locks and ensure smooth suction), and base and enclosure (to fix the pump body, dissipate heat, and facilitate maintenance), supporting normal and stable operation of the pump body.

Basic Principles and System Composition

Installation in place:Preparation: Secure the pump body and connecting pipelines, check each system, add lubricating oil, set control parameters, and ensure all systems are ready. Start-up: Start the power system to drive the pistons in alternating reciprocating motion; simultaneously start the lubrication, spraying, and filling systems, and accelerate to preset parameters. Normal operation: Pistons alternately suck and discharge slurry, air bag stabilizes output; PLC monitors in real time and automatically adjusts speed to ensure stable transport. Exception handling: Immediately alarm and stop the machine when an anomaly is detected, troubleshoot (blockage, leakage, etc.), and restart after repair. Shutdown and finishing: Shut down all systems, close valves, clean the pump body, inspect and replace wear parts, and record maintenance.
