Skylink Fluid Technology
Skylink AODD pumps adopt compressed air for power source and depend on diaphragms which move left and right to
reach the volume sealed working chamber to achieve loading and discharging.
斯凯力气动隔膜泵采用压缩空气作为动力源，依靠向左和向右移动的膜片改变密封的腔体容积来实现进料和出料。
AODD pump is structured by suction port
,
discharge port
,
medium chamber and air chamber, air chamber is
structured by main air valve
，
pilot valve
,
thimble on left diaphragm chamber and right diaphragm chamber,medium
chamber is structured by left medium
,
right medium and check valve. Check valve are set on the top or bottom,left and
right medium chambers are connected by suction port and discharge port.
气动隔膜泵由吸入口、排放口、介质室和空气室构成，空气室由主气阀、导向阀、左膜片室和右膜片室的顶针构成，介质
室为由左介质、右介质和止回阀构成。止回阀设置在顶部或底部，左、右中腔室通过进料口和出料口连接。
When AODD pump is working,left and right diaphragms are moving by compressed air, and the air valve has lubricating
demand, so clear and dry air can improve the performance of AODD pump.
隔膜泵工作时，左右膜片均通过压缩空气运动，气阀有润滑要求，干燥的空气可提高气动隔膜泵的性能。
Compressed air comes into air chamber across air inlet port,after the regulation of pilot valve,compressed air come into
left diaphragm chamber and drive diaphragm move on the left ,the result is that the volume of left medium
chamber decreases,the liquid is extruded.
压缩空气通过进气口进入气室，在导向阀调节后，压缩空气进入左侧隔膜室，驱动膜片向左移动，结果是左腔容积减小，
液体被挤出。
Because the right diaphragm and the left diaphragm are connected by an axle,the right diaphragm moves to the left
side,the right chamber volume increases,the liquid is inhaled. when the right diaphragm plate touches the right thimble,
the right thimble can change the direction of compressed air by pilot valve,air come into the right chamber,the left and
right diaphragm move to the right side,the left medium chamber volume increases,liquid is in inhaled,the right chamber
volume decreases,liquid is excluded. When the left diaphragm plate touches the left thimble,the air comes into left
diaphragm chamber through pilot valve. The actions above are repeated complete the fluid continuous transporting
on by AODD pump.
由于右膈膜和左膈膜通过轴连接，右膈膜向左移动，右腔容积增大，吸入液体。当右膈膜的压板接触右顶针时，右顶针可
通过导向阀改变压缩空气的方向。空气进入右室，左、右膈膜向右侧移动，左腔容积增大，液体吸入，右腔容积减小，液
体被排出。左膈膜压板接触左顶针时，空气进入左腔室，通过导向阀，重复以上动作完成气动隔膜泵的流体连续输送。
SECTION 2
Principle of Pump Operation
工作原理
The Skylink diaphragm pump is an air-operated, positive displacement, self-priming pump. These drawings show the
low pattern through the pump upon its initial stroke. It is assumed that the pump has no fluid in it prior to its initial stroke.
斯凯力隔膜泵是一种气动、正排量、自吸泵。这些图显示了泵在初始冲程时的流型。假设泵在其初始行程之前没有流体。
