蠕动泵管软管接头的选择
Selection of hose joint of peristaltic pump pipe
蠕动泵所产生的吸力是由蠕动泵头的管轮总成挤压软管后软管回弹所产生的。因此，如果所需要传输的流体距离蠕动泵头过长或者软管接头扣边变小会使得吸入端的阻力变大，阻力变大是使蠕动泵软管回弹受阻最终造成实际传输流量损失严重。同理，如果输出端的软管过长或者软管接头口径变小会造成软管内输出阻力变大，造成输出流量变小。
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.
因此在选择蠕动泵软管接头的时候软管接头不要小于泵头装卡软管的口径。同时蠕动泵软管入口处也要尽可能短。
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.
