蠕動(dòng)泵管軟管接頭的選擇
Selection of hose joint of peristaltic pump pipe
蠕動(dòng)泵所產(chǎn)生的吸力是由蠕動(dòng)泵頭的管輪總成擠壓軟管后軟管回彈所產(chǎn)生的。因此，如果所需要傳輸?shù)牧黧w距離蠕動(dòng)泵頭過長(zhǎng)或者軟管接頭扣邊變小會(huì)使得吸入端的阻力變大，阻力變大是使蠕動(dòng)泵軟管回彈受阻最終造成實(shí)際傳輸流量損失嚴(yán)重。同理，如果輸出端的軟管過長(zhǎng)或者軟管接頭口徑變小會(huì)造成軟管內(nèi)輸出阻力變大，造成輸出流量變小。
The suction generated by the peristaltic pump is generated by the hose rebound after the tube wheel assembly of the peristaltic pump head compresses the hose. Therefore, if the distance between the fluid to be transmitted and the peristaltic pump head is too long or the buckle edge of the hose joint becomes smaller, the resistance at the suction end will become larger. The larger the resistance is, the rebound of the peristaltic pump hose will be blocked and the actual transmission flow loss will be serious. Similarly, if the hose at the output end is too long or the diameter of the hose connector becomes smaller, the output resistance in the hose will become larger and the output flow will become smaller.
因此在選擇蠕動(dòng)泵軟管接頭的時(shí)候軟管接頭不要小于泵頭裝卡軟管的口徑。同時(shí)蠕動(dòng)泵軟管入口處也要盡可能短。
Therefore, when selecting the hose connector of peristaltic pump, the hose connector should not be smaller than the diameter of the hose installed on the pump head. At the same time, the inlet of peristaltic pump hose should be as short as possible.
