還有一種食品級橡膠軟管泵，它的內(nèi)襯的橡膠層需要達(dá)到了食品衛(wèi)生的要求，同時也需要符合EHEDG或者其他衛(wèi)生級的要求。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：強氧化溶劑。軟管的內(nèi)層是CSM，外層是天然橡膠。運行溫度達(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.

眾所周知軟管泵在運行時，是通過一根U型附有彈性的橡膠軟管來完成輸送。今天小編需要強調(diào)的是，軟管存放時間不宜過長，一般以一年為限。在停工期間，對裝有軟管的泵，若長期不用，每隔一個月需轉(zhuǎn)動泵一次。以免壓輥長時間壓在泵管的某一處，減弱管子回彈性，影響其流量的輸送。

It is well known that when the hose pump is running, it is conveyed through a U-shaped rubber hose with elasticity. Today the editor needs to emphasize that the storage time of the hose should not be too long, and it is generally limited to one year. During the shutdown period, if the pump is equipped with a hose, if it is not used for a long time, the pump needs to be rotated every other month. So as not to press the roller for a long time at a certain position of the pump tube, it will weaken the resilience of the tube and affect its flow rate.

 

工藝介紹：用傳統(tǒng)的物化法或生物法來處理垃圾滲濾液，不僅效果較差、難以達(dá)標(biāo)，還會存在占地面積大，建成時間長等問題；如果采用包括納濾、反滲透等在內(nèi)的MBR（即膜+生化結(jié)合）工藝進(jìn)行處理，則會存在投資高、工藝復(fù)雜、運行費用高、處理后的濃縮液造成二次污染等各類問題。
