4、to the self- suction centri- fugal pump and uses the mechanical seal of a ceramic ring so as to resist any sandy liquid to go into the sealing face, preventing it from getting scratched. This pump holds the advantages of a compact structure, easy operation, stable movement, easy maintenance, high ef
5、ficiency, long duration and strong self- suction capacity and, as no foot valve is ne- eded to be mounted on the pipeline and only a certain am- ount of leading liquid is required to be filled into the pump before work, improves the work condition while simplifying the pipeline system. This pump can

After the pump is normally started, the impeller
10、 sucks i n t he all liquid inside of the suck- in room and the air inside of the pipeline and gets them completely mixed inside of it, then, under the action of the centrifugal force, the liquid, carrying the air, flows towards the outer edge of the scroll room and, on the outer edge of the impeller
11、, a white foam band of a certain thickness and a quickly rotating l iquid r ing are formed. The air- liquid mixture gets into the air- liquid separating room through the expanding pipe and, as t he f low - rate is abruptly lowered thereafter, the lighter air is separ- ated from the mixture and rises
12、 through the vomit port of the pump casing and is exhausted therefrom. T he l iquid w ith the air off returns to the liquid storing room and gets into the impeller again through the liquid back hole, where it is mixed again with the air sucked in from the suck- in pipe- line and, under the action of
13、 the quickly rotating impeller, flows towards the outer edge of the impeller again , al- ong with the repeated process, the air in t he s uck- in p ipeline is continually reduced till being sucked up, the self- suction process ends and the pump gets into the normal work. This unique exhaust capacity
14、 makes the pump able to transport the air- contained liquid without a foot valve mounted and of a good cabin cleaning function when used on an oil ship. There is a cooling room on the bottom of the bearing body with some pumps and, when the bearing bodys temp- erature rise is over 70oC with the bear

The sealing mechanism inside of the pump used to prevent the liquid from leaking from the high pressure area to the low one is the front and rear seal rings, the f

When the seal ring gets worn out to a certain extent after a long time work of the pump and thus affecting both effici- ency and self- suction property of it, it should be replaced. 1 8 2 9 4 11 3 10 5 12 6 13 7 14 Clutch Inlet seat Pump shaft Front seal ring Bearing Impeller Mechanical seal Rear cover Bearing body Baffle ring Pump casing Liquid filling hole Outlet seat Liquid back hole BRI
