首先我們先介紹一下軟管泵，軟管泵又稱蠕動(dòng)泵。為了泵體污染流體或流體污染泵體的危險(xiǎn)性，整個(gè)泵的裝置中只有軟管與介質(zhì)接觸。在一般場(chǎng)合下，軟管泵使用的都是天然橡膠的軟管。內(nèi)層和外層都是完整光滑的天然橡膠，其目的是很強(qiáng)防磨損。適用于腐蝕性不高但磨損性很大的如泥漿以及無機(jī)物等等介質(zhì)。而且一般適用于脂肪、油類或油脂的介質(zhì)，以及有機(jī)化學(xué)物質(zhì)。內(nèi)層是橡膠，而外層是天然橡膠或者是復(fù)合橡膠。

First of all, lets introduce the hose pump, which is also called peristaltic pump. In order to eliminate the danger of the pump body contaminating the fluid or the fluid contaminating the pump body, only the hose in contact with the medium in the entire pump device. In general, hose pumps use natural rubber hoses. The inner and outer layers are completely smooth natural rubber, the purpose of which is to prevent abrasion. It is suitable for mediums that are not corrosive but very abrasive, such as mud and inorganic substances. And generally suitable for fats, oils or oils, and organic chemicals. The inner layer is rubber, while the outer layer is natural rubber or composite rubber.

 

擠壓輪的結(jié)構(gòu)設(shè)計(jì)與拖鞋結(jié)構(gòu)設(shè)計(jì)：
與擠塑輪結(jié)構(gòu)設(shè)計(jì)相比，膠管泵的滑靴設(shè)計(jì)能承受更高的壓力，因此要根據(jù)泵的需求壓力和具體應(yīng)用情況來決定哪種設(shè)計(jì)適合。擠壓輪設(shè)計(jì)只需在軟管表面涂上硅脂，不需要額外的潤(rùn)滑油，因?yàn)闈L筒在軟管表面“滾動(dòng)”。因此，該設(shè)計(jì)可考慮用于涉及食品和飲料的應(yīng)用，因?yàn)樵谲浌芄收虾蛿嗔训那闆r下，交叉污染的概率小于浸沒在潤(rùn)滑油中的拖鞋設(shè)計(jì)蠕動(dòng)泵的概率，即使油是“食品級(jí)”，通常也 使用滾筒設(shè)計(jì)。
