还有一种食品级橡胶软管泵，它的内衬的橡胶层需要达到了食品卫生的要求，同时也需要符合EHEDG或者其他卫生级的要求。还有三元乙丙橡胶软管泵，这种一般适用于绝大多数腐蚀性的化学物质和无机物，内衬橡胶层由三元乙丙橡胶构成，外层也是完整的三元乙丙橡胶。这样的软管具备很强的抗化学腐蚀的特性。以及CSM软管泵，它适用于特别腐蚀性的化学介质，如：强氧化溶剂。软管的内层是CSM，外层是天然橡胶。运行温度达到85℃/185°F。

There is also a food-grade rubber hose pump. Its rubber layer must meet food hygiene requirements, and it must also meet EHEDG or other sanitary requirements. There is also a EPDM hose pump, which is generally suitable for most corrosive chemicals and inorganic materials. The inner rubber layer is composed of EPDM rubber, and the outer layer is also a complete EPDM rubber. Such hoses have strong chemical resistance. And CSM hose pump, it is suitable for particularly corrosive chemical media, such as: strong oxidizing solvents. The inner layer of the hose is CSM and the outer layer is natural rubber. Operating temperature reaches 85 ° C / 185 ° F.

当齿轮连续转动时，当两啮合点在节点两侧对称位置时，闭合体积逐渐减小。引进润滑泵的叶片泵。为了让您更好的了解我们的产品，并向您讲解齿轮油泵的保养方法：润滑频繁，电动油桶泵高速运转，润滑脂易挥发，所以必须保持轴承处的润滑清洁，并注意更换。利用泵控技术制作环件，可以提高数据的应用率，简化制造工艺，节省数据和加工时间，如目前普遍采用耐磨泵管制作的泵管、管件等。从结构上看，它像一个单向阀，所以也可以参考单向阀的维修方法。
