絕大多數(shù)蠕動泵系統(tǒng)都包括三個組件:泵頭、泵管,以及驅(qū)動器,下面我們就來談談,組件的選購要點;
Most of the peristaltic pump system comprises three components: pump
head, pump, and drive, we are going to talk about, buy points of
components;
1.選擇管
1. selection tube
◆作為蠕動泵軟管的條件
As the peristaltic pump hose condition
·具有一定彈性,即軟管徑向受壓后能迅速恢復形狀
? a certain flexibility, that is, the hose can be quickly restored to shape after radial compression
·具有一定的耐磨性
It has a certain wear resistance
·具有一定承受壓力的能力
? ability to cope with pressure
·不滲漏(氣密性好)
No leakage (good air tightness)
·吸附性低、耐溫性好、不易老化、不溶脹、抗腐蝕、析出物低等
Low adsorption, good temperature resistance, aging, swelling, corrosion resistance and low precipitation
◆選擇軟管應考慮如下因素
The choice of hose should consider the following factors
·抗化學腐蝕性/化學相容性
Chemical resistance / chemical compatibility
傳輸不同的流體時,軟管應表現(xiàn)出一定優(yōu)良化學性能,即稱之為化學相容。如:吸附性低、耐溫性好、不易老化、不溶脹、抗腐蝕、析出物低等
When transporting different fluids, the hose shall exhibit certain good
chemical properties, which is called chemical compatibility. Such as:
low adsorption, good temperature resistance, not aging, swelling,
corrosion resistance, low precipitation
抗化學腐蝕性能隨溫度的升高而降低,在室溫下對管沒影響的化學藥品可能隨溫度升高對軟管產(chǎn)生影響。
The resistance to chemical corrosion decreases with increasing
temperature, and chemicals that do not affect the tube at room
temperature may have an effect on the hose as the temperature increases.
·承壓
Pressure bearing
蠕動泵的應用受軟管承壓性能的限制。
The application of peristaltic pump is limited by the pressure bearing performance of the hose.
如果系統(tǒng)壓力達到超過軟管的極限承壓,軟管會膨脹,導致軟管的過度磨損或軟管破裂。
If the system pressure exceeds the limit of the hose, the hose will expand and cause excessive wear of the hose or hose rupture.
影響軟管承壓的因素有:材料、直徑與壁厚的比例等。
The factors affecting the pressure of the hose include material, diameter and wall thickness.
·溫度
Temperature
軟管適應工作溫度范圍是用戶要考慮的因素。不同材料有不同的溫度表現(xiàn)。
Flexible hose operating temperature range is a factor for users to
consider. Different materials have different temperature performance.
·尺寸
Size
軟管的尺寸對流量有直接影響,優(yōu)秀泵設計會考慮適用軟管的內(nèi)徑和壁厚,匹配最佳軟管尺寸或管號范圍。軟管的內(nèi)徑?jīng)Q定了流量;壁厚影響軟管被壓縮回彈的能力,對軟管的壽命也有很大影響。
The size of the hose has a direct bearing on the flow. Excellent pump
design will take into account the inner diameter and wall thickness of
the hose and match the best hose size or pipe number range. The inner
diameter of the hose determines the flow rate; the wall thickness
affects the hose's ability to compress and rebound; it also has a great
effect on the life of the hose.
·認證
Certified
軟管用于相關(guān)用途時可能要通過相關(guān)的認證。如美國藥典標準USP, 歐洲藥典標準EP,美國食品藥物管理標準FDA, 美國農(nóng)業(yè)部標準USDA和國家衛(wèi)生基金會標準NSF。
Hoses used for related purposes may be subject to relevant
certification. Such as USP standard USP, European Pharmacopoeia Standard
EP, American food and drug administration standard FDA, USDA standard
USDA and national health foundation standard NSF.
·軟管的柔性/彈性/壽命
Flexible / flexible / life of hose
不同軟管耐滾輪反復擠壓、摩擦的能力不同。不同的管型、管材、泵頭、運行速度有不同的壽命。使用壽命在泵系統(tǒng)中叫柔性壽命,在特定的應用中,泵的特性是很一致的。選擇長壽命、厚壁管,選用大流量泵,運行在較低轉(zhuǎn)速時可以獲得更長的軟管使用壽命。
Different hose, roller resistance, repeated extrusion, friction ability
is different. Different pipe types, tubing, pump head and running speed
have different life. The service life is called the flexible life in the
pump system, and the pump characteristic is very consistent in the
specific application. Choose long life, thick wall pipe, choose large
flow pump, run at a lower speed, you can get longer hose life.
