AY type lubropump series, which is reformed and redesigned on the base of original Y type lubropump series. In order to meet the construction of the modernization and adapt to the requirement of replacing the old with the new one soon which is focused on the saving the energy,so we develop this new product, it has the following characteristics:
1.The original bearing body parts35,50,60 are replaced by bearing body45,55,70 in this way, its reliability can be increased.
2.The hydraulic excess flow part adopt the hydraulic model of the high efficiency energy saving pump, in average, the efficiency is 58% higher than the old Y type lubropump.
3.In order to keep inheriting the strueture pattern, installing size, performance parameter all keep the same with the Y type lubropump, so it is very convenient for renewing and recinstructing.
4.The lubropump parts have the strong all-purpose ability, its generalstandaed parts can be commonly used by several series.
5.The affinage of its selecting materials way and the principals part is mainly made of II III kind material, the materials of some parts such as bearing body is up two kinds, that is casting steel and casting iron, in this way, it makes very advantageous for being used in the cols area, being used outdoor, using for ship-making.
6.According to the different service temperature, selecting bearing has three types, that is air cooling, air fan cooling, water cooling. Among them, air fan cooling is especially used for the area where the water resource is lack or the quality of water is worse.
AY type lubropump can be divided into six kinds, that is Single-stragle suction and two-stage suction cantilever,single stage double suciton cantilever, single stage double suction and two stage double suction dual bearing type two stage single suction dual bearing type. The structure type is the chart 1 to chart 6.
Casing radial split,especially used for transporting the liquid which is high temperature, high pressure, inflammable, explosive or poisonous. Its installing way is supporting with the horizontal central line. The suction port flange and discharge part flange of the pump are all cast on the pump casing, and then are all in vwetical and upward direction. Gland seal cavity(pscling box) and cover are cast together, packing seal, balanced seal, bellows seal, tandem mechanical seal can all be put into the packing box. Out of the gland seal cavity, there is the selective water-cooling cavity jacket which is cast on it, the equipment of the water-cooling cavity must be used in this kind if the situation, that is specially put forward when transporting the hydraulic whose temperature is over 150ºC.
The impeller is cast integrally, and after static balancing, the axial force of the pump is mainly depend all the balanced cavity of the impeller to keep its balancing. There are radial ball bearing and a set thrust ball bearing, which is installed back to back on the bearing body. Its bearing adopt oil slinger to lubricate it. Fins are cast on the surface of the bearing body, it can be aircooled, we also can choose fan cooling (T=120ºC-260ºC) and watercooling(T=260ºC-420ºC)
In order to easily dismounting the parts such as impeller, shaft, bearing or gland seal,mean while we don't need to dismantle the suction line or discharge line while the pump is on the overhaul . We always adopt metallic flexible laminated memnrane couplings.
