Guidelines for Selecting and Applying Acid-and Alkali-Resistant Magnetic Pump Models
The medium’s hazardousness determines whether a magnetic pump should be used; its corrosiveness and temperature determine the appropriate material selection. The minimal leakage rate of a pump directly determines the safety level of the process. Magnetic pumps employ magnetic coupling instead of mechanical seals, structurally eliminating leakage pathways. In applications involving flammable and explosive substances,…
Google’s liquid cooling demand far exceeds expectations: With a guidance of 33,000 CDUs over two years, China’s supply chain faces a historic opportunity
NVIDIA GPUs are not the sole winners in the AI computing power race. Leading ASIC chip manufacturers like Google are forging a distinct growth path based on their proprietary TPU architectures, driving demand for liquid cooling infrastructure at an unprecedented pace. The key findings from Google’s recent Supply Chain Conference indicate that the company forecasts…
High-frequency failures in high-power magnetic pumps
Abstract: This paper examines the P-106 circulating benzene pump from three perspectives—structural design, operating principles, and practical operation—highlighting frequent operational failures during its service that led to multiple shutdowns, resulting in emergency equipment halts, significant operational complexity, high maintenance frequency, and difficulties in scheduled switching. The study conducts a root cause analysis and proposes corresponding…
Why does a magnetic pump lose its magnetism?
The fundamental cause of demagnetization in a magnetic pump is that the temperature of its internal permanent magnet exceeds the material’s tolerance limit. Once this critical temperature is surpassed, the magnet’s magnetism undergoes irreversible attenuation or even complete loss. In simple terms, high temperature is the direct culprit behind demagnetization, while various improper operating conditions…
NVIDIA has finalized its next-generation liquid cooling strategy: shielded pumps will become standard equipment in CDUs, marking a technological turning point for the liquid cooling pump market.
The surge in original AI computing power is driving a complete transformation in data center architecture. At GTC Taipei and Computex, NVIDIA announced that its next-generation 800V HVDC (High-Voltage Direct Current) CDU will fully adopt high-voltage DC electronic shielded pumps. This marks a pivotal technological shift in the liquid-cooled CDU pump sector, with zero-leakage, high-performance…
Structure and Working Principle of a Pumped-Space Shield
A centrifugal pump connects the pump to an electric shaft via a coupling, enabling both the pump shaft and motor to rotate simultaneously. In contrast, a canned motor pump is a seal-free design where both the pump and drive motor are enclosed within a pressure vessel filled with the fluid being pumped. This vessel features…
