擠壓輪的結構設計與拖鞋結構設計：
與擠塑輪結構設計相比，膠管泵的滑靴設計能承受更高的壓力，因此要根據泵的需求壓力和具體應用情況來決定哪種設計適合。擠壓輪設計只需在軟管表面涂上硅脂，不需要額外的潤滑油，因為滾筒在軟管表面“滾動”。因此，該設計可考慮用于涉及食品和飲料的應用，因為在軟管故障和斷裂的情況下，交叉污染的概率小于浸沒在潤滑油中的拖鞋設計蠕動泵的概率，即使油是“食品級”，通常也 使用滾筒設計。                             

軟管泵工作原理：
一根內壁光滑，強度可靠的特制橡膠軟管安裝在泵體內部，通過一對壓輥沿著軟管旋轉擠壓，這樣的 旋轉使得介質往一個方向輸送而不會倒流，軟管在輸送介質之后，由被壓扁軟管的自身彈性和側導輪的強制下，軟管恢復原狀，此時，軟管內產生高真空將介質再次吸入管腔，然后介質在隨之而來的壓輥擠壓下從軟管內排出，如此周而復始，介質不斷的被吸入和排出。目前產品使用溫度為≤100℃。根據用戶需要可以開發(fā)使用溫度在120℃的軟管泵軟管產品。
Working principle of hose pump:
A special rubber hose with a smooth inner wall and reliable strength is installed inside the pump body. It is rotated and squeezed along the hose by a pair of pressure rollers. This rotation allows the medium to be transported in one direction without flowing back. After that, due to the elasticity of the flattened hose and the force of the side guide wheels, the hose returns to its original state. At this time, a high vacuum is generated in the hose to suck the medium into the lumen again, and then the medium is pressed by the subsequent pressure roller. It is discharged from the hose under the squeeze, and so on and on, the medium is continuously sucked in and discharged. The current product temperature is ≤100 ℃. According to user needs, we can develop hose pump hose products with a temperature of 120 ℃.
