单螺杆泵 Single screw pump   单螺杆泵是一种常用的容积式泵，主要由单螺杆转子和固定的螺杆衬套（通常由橡胶材料制成）组成。该泵的设计使其能够出色地处理各种粘度的流体，包括高粘度液体、含固体颗粒的液体以及易沉淀或固化的产品。 Single screw pump is a commonly used positive displacement pump, mainly composed of a single screw rotor and a fixed screw liner (usually made of rubber material). The design of this pump enables it to perform excellently in handling fluids of various viscosities, including high viscosity liquids, liquids containing solid particles, and products that are prone to precipitation or solidification.   单螺杆泵的主要特点包括： 1.自吸能力：能够从低位或远距离吸取液体。 2.流量均匀：输出稳定，脉动最小。 3.高效率：即使在高压下也能保持高效率。 4.适用范围广：可输送各种介质，包括腐蚀性液体和含有一定量固体颗粒的悬浮液。 5.结构简单：维护方便，使用寿命长。 The main features of a single screw pump include: 1. Self suction ability: able to suck liquid from a low position or a long distance. 2. Uniform flow: stable output with minimal pulsation. 3. High efficiency: It can maintain high efficiency even under high pressure. 4. Wide applicability: It can transport various types of media, including corrosive liquids and suspensions containing a certain amount of solid particles. 5. Simple structure: easy maintenance, long service life.   主要应用   威弗德单螺杆泵广泛适用于食品、饮料、酿酒、造纸、电力、化工、石油、冶金、建筑以及环境工程等众多领域；在石油工业中，主要用来输送原油、稠油、各种催化剂、聚合物（油田注聚）、油泥、含油污水、公用工程等工况。产品符合ISO和API676标准。     Weford single screw pumps are widely used in various fields such as food, beverage, brewing, papermaking, power, chemical, petroleum, metallurgy, construction, and environmental engineering; In the petroleum industry, it is mainly used to transport crude oil, heavy oil, various catalysts, polymers (oilfield injection), oil sludge, oily wastewater, public engineering and other working conditions. our screw pump are made as per ISO and API 676 standard。
