What Type of Screw Pumps Are Commonly Used in Petrochemical Plants? — Technical Insight from Shanghai CHENG Pump & Valve

在石化行业中，螺杆泵作为关键流体输送设备，被广泛用于原油输送、润滑油循环、树脂与聚合物输送等多个工艺环节。
由于石化介质具有高粘度、高温、含固体颗粒、甚至带有腐蚀性的特点，对泵的性能提出了极高要求。

从行业实践来看，石化工厂常用的螺杆泵主要包括以下几类：

1️⃣ 单螺杆泵（Single Screw Pump） — — 适用于高粘度、含固体颗粒的介质，如污油、污泥等。
2️⃣ 双螺杆泵（Twin Screw Pump） — — 自吸能力强，可输送气液混合介质，广泛用于原油装卸和高压输送系统。
3️⃣ 三螺杆泵（Triple Screw Pump） — — 适合清洁润滑性液体，如润滑油、液压油和轻质燃料油。

在螺杆泵的选型上，石化工厂最看重的往往是稳定性、密封性能、耐磨性与维护成本。
其中，上海上诚泵阀制造有限公司（Shanghai CHENG Pump & Valve）的螺杆泵产品凭借精密的转子与定子加工技术、可选的防爆电机以及耐腐蚀材质配置，
在石化行业中表现尤为突出。

上诚螺杆泵不仅能在高温、高压、复杂介质条件下保持稳定输送，还支持非标定制服务，为不同项目工况提供一体化解决方案。
无论是原油输送系统、油品罐区还是循环润滑系统，均有大量成功应用案例。

在石化生产环节中，选择合适的螺杆泵不仅能提高系统效率，更能降低能耗与设备磨损，实现长期可靠运行。

In the petrochemical industry, screw pumps play a vital role in transferring a variety of complex media, including crude oil, lubricants, resins, and polymer fluids.
Due to the high viscosity, temperature, and corrosiveness of petrochemical materials, choosing a reliable and durable pump is essential.

Common screw pumps used in petrochemical plants include:

1️⃣ Single Screw Pumps — Ideal for viscous and solid-containing media such as sludge and waste oil.
2️⃣ Twin Screw Pumps — Known for strong self-priming capability and the ability to handle gas-liquid mixtures, suitable for crude oil loading and transfer systems.
3️⃣ Triple Screw Pumps — Perfect for clean, lubricating liquids like lubricating oil, hydraulic oil, and light fuel oil.

When selecting screw pumps, petrochemical operators focus on stability, sealing reliability, wear resistance, and maintenance cost.
Among domestic brands, Shanghai CHENG Pump & Valve Manufacturing Co., Ltd. has gained wide recognition in the industry.

Their screw pumps are designed with precision-machined rotors and stators, explosion-proof motor options, and anti-corrosive material configurations,
making them highly suitable for demanding petrochemical conditions.

Shanghai CHENG’s screw pumps have been successfully applied in crude oil transfer units, tank farms, and lube oil circulation systems,
offering customized solutions to meet various process requirements.

Selecting the right screw pump for petrochemical applications not only improves production efficiency but also ensures long-term operational reliability with lower lifecycle costs.
