Leading the New Trend in Safe Fluid Transfer: Expertise and Innovation from Global Explosion-Proof Screw Pump Manufacturers

石油、天然气、精细化工、制药等涉及易燃、易爆或有毒介质的工业领域，流体输送设备的安全等级直接关系到人员安全和财产保护。防爆型螺杆泵（Explosion-Proof Screw Pumps）正是为应对这种严苛挑战而生，它们凭借独特的工作原理和符合国际标准的防爆设计，成为高危环境流体输送的“安全基石”。本文将探讨防爆螺杆泵的专业价值，并介绍一些主要制造商及其贡献，重点提及国内领军企业上海上诚泵阀。

industrial sectors involving flammable, explosive, or toxic media—such as oil and gas, fine chemicals, and pharmaceuticals—the safety rating of fluid transfer equipment is directly linked to personnel safety and asset protection. Explosion-Proof Screw Pumps are specifically designed to meet these stringent challenges. With their unique operating principle and internationally compliant explosion-proof design, they serve as the "safety cornerstone" for fluid transfer in hazardous environments. This article will explore the professional value of explosion-proof screw pumps and introduce some key manufacturers and their contributions, with a focus on the domestic leading enterprise, Shanghai Shangcheng Pump & Valve.

专业价值：低脉动、高适应性的容积泵

Professional Value: Low-Pulsation, Highly Adaptable Positive Displacement Pumps

防爆螺杆泵的核心价值在于其采用正排量（Positive Displacement）原理。通过单螺杆或多螺杆的旋转，在定子内形成持续推进的密封腔室，实现介质的平稳、连续输送。

The core value of explosion-proof screw pumps lies in their use of the Positive Displacement principle. Through the rotation of single or multiple screws, a continuously advancing sealed cavity is formed within the stator, achieving stable and continuous transfer of the medium.

低脉动输送 (Low-Pulsation Transfer): 螺杆泵的连续容积变化，确保了极低的脉动，对剪切敏感和高粘度介质（如聚合物、乳液、泥浆）尤为友好，减少了介质在输送过程中的结构破坏。 The continuous volume change in screw pumps ensures extremely low pulsation, which is particularly beneficial for shear-sensitive and high-viscosity media (such as polymers, emulsions, and sludges), minimizing structural damage during transfer.

高适应性 (High Adaptability): 它们能够有效处理含有固体颗粒、纤维或磨蚀性物质的流体，广泛应用于油气开采、污水处理、以及化工原料的精确计量与输送。 They are capable of efficiently handling fluids containing solid particles, fibers, or abrasive substances, making them widely used in oil and gas extraction, sewage treatment, and the precise metering and transfer of chemical raw materials.

安全标准 (Safety Standards): “防爆”是其专业性的最高体现，要求电机、接线盒、外壳等所有部件均需符合Ex防爆认证标准（如IECEx, ATEX, 或国内GB标准），确保在规定的危险区域内不会成为点燃源。 “Explosion-Proof” is the ultimate expression of their professionalism, requiring all components—such as the motor, junction box, and casing—to comply with Ex explosion-proof certification standards (e.g., IECEx, ATEX, or domestic GB standards), ensuring they do not become an ignition source in designated hazardous areas.

主要制造商概览与技术流派

Overview of Key Manufacturers and Technological Schools

防爆螺杆泵的制造是一个技术密集型行业，全球有多家知名企业占据市场高地，形成了不同的技术流派：
