AY Single Two Stage Centrifugal Pump 


>>>Brief introduction
AY series single two stage centrifugal pumps which are reformed and redesigned on the base of original Y type lube pump series. In order to meet the construction of the modernization adapt to the requirement of replacing the old with the new one soon which is focused on the sizing 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 5-8% higher than the old Y type lube pump.
   3. In order to keep inheriting, the structure pattern, install size.
   4. The lube pump pats have the strong all-purpose ability, its general-standard parts can be commonly used by several series.
   5. The affiance 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 to two kinds, that is casting steel and casting iron, in this way, it makes very advantages for being used in the cold area, being used outdoor, using for ship making.
   6. According to the different temperature, selecting hearing 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.

>>>Performance Scope: 

flow capacity: Q=2.5-600m3/h lift : H=30~330m Temperature: T=-45 deg C to 420 deg C.

    

>>>Application: 

AY-type centrifugal oil pump can be used in different field such as petroleum refining, petrochemical, chemical industry, the other field which transport the petroleum, liquid gas and the other medium which doesn't contain the particulate solids.
Illustration 

>>>Model Explaination: 


200AY150B


"200" means the diameter of suction port(mm) 
"A" means The first time alteration  

"Y" mean centrifugal oil pump  

"150" means single lift(m) 2--class 
"B" means impeller cutting times , the order will be showed as A,B... 

>>>Structure characteristics 
    AY centrifugal oil pump can be divided into six kinds that are single- stage single suction and TWO-stage single suction cantilever, single stage double suction cantilever, single stage double suction and TWO stages double suction dual bearing type, Two stage single suction data bearing type. 
    The impeller is cat integrally, an after static balancing, the axial force of the pump is mainly depend on 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 is bearing adopt oil slinger to lubricate it fins are cadet on the surface of the bearing body , it can be air -cooled ,we also can choose fan-cooling (T=120 deg C-260 deg C)and water-cooling(T=260 deg C-420 deg C).
    In order to easily dismounting the parts such as impeller, shaft, bearing so gland seal, meanwhile 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 membrane couplings. 

>>>The pump line system 
    1. According to the temperature and the demand of application we use cooling-water to cool the shaft seal capacity, bearing or pump mounting the water amount for per pipe is 0.3-0.7m3/h,its pressure 0.2-0.3MPa.
    2. Sealing flush is changing according to the different transporting medium and its temperature pressure or the other working condition, the seal liquid amount for per pump is as following table, both inter supply and outer supply is suitable for that.

Sealing nominal diameter (mm) 13-47 48-59 60-84 85-95 96-133
Average seal liquid amount (m3/h) 0.18 0.24 0.36 0.48 0.66

 
 The pressure of the seal liquid is usually higher than the pressure of the sealing capacity 0.07-0.1MPa,if the transporting medium is easily vaporizing, the hat pressure should be higher than the caponizing pressure 0.175-0.2MPa.
    3. Steam line is equipped in case the transporting medium is easily precipitation crystal; its pressure should be 0.1MPa less or more. 
The material list of the excess flow parts 
According to the different service condition, the main parts of the pump can be decided in three dints, the details is as following chart 

         Material type  I II III
service temperature -20 deg C~+150 deg C -45 deg C~+420 deg C -45 deg C~+420 deg C
