還有一種食品級(jí)橡膠軟管泵，它的內(nèi)襯的橡膠層需要達(dá)到了食品衛(wèi)生的要求，同時(shí)也需要符合EHEDG或者其他衛(wèi)生級(jí)的要求。還有三元乙丙橡膠軟管泵，這種一般適用于絕大多數(shù)腐蝕性的化學(xué)物質(zhì)和無機(jī)物，內(nèi)襯橡膠層由三元乙丙橡膠構(gòu)成，外層也是完整的三元乙丙橡膠。這樣的軟管具備很強(qiáng)的抗化學(xué)腐蝕的特性。以及CSM軟管泵，它適用于特別腐蝕性的化學(xué)介質(zhì)，如：強(qiáng)氧化溶劑。軟管的內(nèi)層是CSM，外層是天然橡膠。運(yùn)行溫度達(dá)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.

軟管泵屬于蠕動(dòng)泵的范疇，主要是由一根特制的橡膠軟管，對(duì)應(yīng)泵體內(nèi)轉(zhuǎn)子總成上的一對(duì)壓輥，當(dāng)壓輥沿著橡膠軟管轉(zhuǎn)動(dòng)時(shí)，壓輥與泵殼產(chǎn)生的擠壓力將橡膠軟管壓扁，在軟管自身彈性和側(cè)導(dǎo)輥的強(qiáng)制下，通過恢復(fù)原狀產(chǎn)生的真空吸入流體物料，物料在壓輥的機(jī)械擠壓下從管內(nèi)排出，如此往復(fù)循環(huán)，從而達(dá)到連續(xù)輸出物料的目的。

The hose pump belongs to the category of peristaltic pump. It is mainly composed of a special rubber hose corresponding to a pair of pressure rollers on the rotor assembly in the pump body. When the pressure roller rotates along the rubber hose, the pressure roller and the pump housing The squeezing force flattens the rubber hose. Under the elasticity of the hose itself and the force of the side guide rollers, the fluid material is sucked in by the vacuum generated by the original state. The material is discharged from the tube under the mechanical pressure of the pressure roller, and so on. , So as to achieve the purpose of continuous output of materials.
