Description

CQB-G High-temperature Water-cooled Magnetic Drive Centrifugal Pump Product Details
1. Product Overview
The CQB-G high-temperature water-cooled magnetic drive centrifugal pump is a special upgraded magnetic pump designed for high-temperature corrosive and high-risk medium closed-loop transportation. Composed of four core modules: motor, high-precision magnetic coupler, independent water cooling device and anti-corrosion pump body, it breaks the limitations of ordinary normal-temperature magnetic pumps such as high-temperature demagnetization and thermal failure.
Adopting a dual cooling system of circulating water cooling and external fan heat dissipation, it stably handles media temperature up to 300℃. The pin coupling and split structure reduce vibration and noise, realizing full static sealing and zero leakage. With a rated working pressure of 1.6MPa, it adapts to high-density and medium-viscosity high-temperature fluids. It is widely used in petroleum, chemical, pharmaceutical, printing and dyeing industries for safe transportation of high-temperature acid-base, oil, volatile toxic and flammable explosive precious media.
2. Core Product Advantages
1. Multiple Water-cooling Heat Dissipation, Anti-demagnetization & Constant Temperature Operation
Equipped with an independent circulating water cooling system and external rotor heat dissipation fan, it forms a dual water-air cooling system to continuously take away internal high-temperature heat. It fundamentally solves the common failures of ordinary magnetic pumps such as magnetic steel demagnetization, bearing burnout and cavity thermal deformation under high temperature, ensuring stable torque transmission and long-term continuous operation under 300℃ ultra-high temperature working conditions.
2. Composite Shock-absorbing Transmission, Low Noise & High Stability
The combined structure of pin coupling and detachable design buffers mechanical vibration and impact under high-temperature operation, reducing noise and component wear effectively. The extended pump body optimizes the heat dissipation space, avoids heat accumulation, and supports 24-hour uninterrupted continuous industrial operation with stable and jitter-free performance.
3. Full Static Sealing Zero Leakage, High Safety for High-risk Working Conditions
Non-contact magnetic coupling power transmission completely eliminates traditional mechanical dynamic seals and leakage risks. The fully closed flow structure prevents volatilization and leakage of high-temperature flammable, explosive, toxic and corrosive media, avoiding safety accidents and site pollution, and meeting explosion-proof and clean production standards for high-temperature workshops.
4. Strict High-temperature & High-pressure Adaptation, Strong Parameter Bearing Capacity
Calibrated for extreme high-temperature working conditions, with a stable working temperature ≤280℃, instantaneous maximum temperature up to 300℃ and maximum working pressure of 1.6MPa. It adapts to clean high-temperature fluids with density ≤1840kg/m³ and viscosity ≤30mm²/s, with large parameter redundancy and wide working condition coverage.
5. Modular Detachable Design, Convenient High-temperature Maintenance
The integrated detachable structure enables quick disassembly and replacement of vulnerable parts without dismantling the whole pipeline. The independent water cooling system can adjust the water flow according to medium temperature for precise constant temperature control. The standardized 1000-hour maintenance cycle greatly reduces the difficulty and cost of high-temperature equipment maintenance.
6. Wide-spectrum Conveying, Multi-industry Universal Adaptation
It stably transports high-temperature acid-base corrosive liquid, oil, organic solvent, toxic volatile media and precious fluids, and supports matching operation of high-temperature circulating water equipment and filter units. It integrates high temperature resistance, corrosion resistance, explosion protection and cleanliness, adapting to refined high-temperature production working conditions in various industries.
3. Working Principle
The CQB-G high-temperature water-cooled magnetic pump operates based on the permanent magnet non-contact coupling transmission and multi-circulation water cooling constant temperature principle. The motor drives the outer magnetic rotor through the pin coupling, and the magnetic field synchronously drives the inner magnetic steel and impeller without mechanical contact and torque loss, realizing zero-leakage power transmission.
During operation, the independent water cooling system continuously cools the magnetic coupling and bearing cavity, and the external heat dissipation fan performs forced air cooling to avoid magnetic demagnetization and thermal wear. The high-speed rotating impeller completes suction, pressurization and stable discharge of high-temperature media. The medium assists in bearing lubrication and cooling, and multiple protection measures ensure long-term stable operation under ultra-high temperature working conditions.
4. Standard Installation & Operation Specifications
1. Installation Requirements
Horizontal installation is mandatory to ensure smooth water cooling and pipeline flow. Check the lubricating oil level of the cooling box before operation and replenish oil in time if the level is insufficient to protect transmission components.
2. Water Cooling System Operation
Follow the principle of "water first, startup later". Turn on the cooling water circuit in advance, and adjust the inlet valve opening according to the outlet water temperature during normal operation to achieve precise constant temperature control. Dry startup without cooling water is strictly prohibited.
3. Pipeline Matching Rules
Open the inlet valve directly when the liquid level is higher than the pump axis. Install a bottom valve on the suction pipeline for negative pressure working conditions to prevent medium backflow and dry running damage.
4. Pre-start Inspection
Check that the motor fan rotates flexibly without jamming and abnormal noise, fasten all fasteners, and confirm the motor rotation direction is consistent with the pump marking to avoid reverse rotation damage.
5. Standard Start-stop Process
Start the motor with no load, slowly open and adjust the discharge valve after stable operation. Before shutdown, close the discharge valve first, cut off the power supply, and finally close the cooling water valve to realize standardized shutdown protection.
5. Key Precautions & Maintenance Specifications
1. Strictly Prohibit Dry Running & Liquid-lost Operation
Bearings rely entirely on conveying medium for lubrication and auxiliary cooling. No-load operation and liquid-lost operation are strictly prohibited to prevent irreversible burnout of bearings and end-face rings.
2. Medium Impurity Control
Install a filter for media with solid particles and a magnetic filter for ferromagnetic particles to avoid wear of high-precision bearings and isolation sleeves.
3. Working Parameter Limit
Operate strictly within the rated range: medium temperature ≤280℃ (instantaneous 300℃), working pressure ≤1.6MPa, density ≤1840kg/m³, viscosity ≤30mm²/s. Over-parameter operation is prohibited.
4. Timely Cleaning for Crystalline Media
Drain and clean the pump cavity thoroughly after operation for precipitable and crystalline high-temperature media to prevent crystal blockage and impeller jamming.
5. Periodic Professional Maintenance
After 1000 hours of operation, disassemble and inspect the wear and thermal damage of bearings and end-face moving rings, replace failed vulnerable parts in time to restore rated high-temperature working performance.
6. Magnetic Safety Warning
Equipped with high-performance permanent magnets with strong magnetic field. Keep magnetic-sensitive devices such as pacemakers, credit cards and calculators away from the pump body to avoid magnetic interference and safety risks.
6. Core Application Scenarios
