Product Overview BY type centrifugal oil pump includes
single-stage cantilever centrifugal pumps, single-two-stage two-end
supporting centrifugal oil pump and multistage centrifugal oil
pumps three sub- series. Single-stage cantilever centrifugal oil
pump is developed and renovated by the Shenyang Water Pump
Institute and this company, on basic of single-two cantilever
centrifugal pumps of the old Y -type centrifugal pumps, drawing
lessons of various characteristics from the existing domestic
centrifugal oil pumps, and in accordance with the American
Petroleum Institute "API**0 petroleum , heavy chemical and
industrial gas pump " standard.
Applications:petroleum refining , petrochemical and chemical
industries , and delivery of liquid petroleum gas and other media
without solid particles;
Performance advantages:the basic performance parameters inherited Y
-type centrifugal pump type spectrum, easy for selection and
replacement. Execution API**0 standards; Cancel the two-stage
structure cantilevered form, enhances the rotor stiffness, high
reliability, small size, light weight, high efficiency hydraulic
model selection; Efficiency up of **8 % compared with Y -type ,
good cavitation performance;
Technical Parameters:Flow Q = 1.****0m3 / h, head H =
*****5m, Transmission medium temperature t = **5 ℃ - ***0
℃.
Performance
advantages: 1,Basic performance parameters inherited Y-type
centrifugal pump type spectrum, easy for selection and
replacement; 2,Implementation API**0 standard; pump discharge
size cancel the diameterΦ*5,Φ**5, etc.; pump materials perform API**0
standard specifications. 3, Abolition of two cantilevered structure
type; 4, Enhances the rigidity of the rotor, to
improve the reliability; 5.Small size and light weight to reduce
manufacturing costs of the pump, and enhance market
competitiveness; 6, Best selection of efficient hydraulic model,
the efficiency up of **8% compared with Y-type offers good
cavitation performance.
Applications BY cantilever single-stage centrifugal pump is
mainly used in petroleum refining and transporting petroleum
processing apparatus and its products, as well as transportation of
flammable, explosive, toxic cleaning liquids and other similar
liquids. Flow rate Q = 1.****0m3 / h, head H = *****5m,
the transmission medium temperature t = **5℃-
***0℃
Structural features BY cantilever single-stage centrifugal pump is
cut spit up, with two suction ways: axial suction and top
suction. When the transmission medium temperature t
<**0 ℃,use of standard API**0 OH1 structure, means pump
foot-mounted type; when transmission medium temperature ≥ **0 ℃,use
of OH2 structure API**0 standards, means pump centerline mounted
type. Radially split casing, particularly suitable for
conveying high temperature, high pressure and flammable, explosive
or toxic liquids. Seal chamber (stuffing) outside is cooling room,
to cool; seal type can be soft packing seal and mechanical seal,
execute "API**0 standard" requirement, selection by user on basic
of a variety of mechanical seals and piping systems for
single-stage pump cantilever households. Pump case is rare-open structure, with a
diaphragm pump coupling with longer segments, repair piping and
pumps without moving the core components of the motor , good
maintenance. The impeller is whole casting type, the balance
of axial impeller advocated rely on back-sealing ring and impeller
balance hole, residual axial force to withstand by a diagonal
contact ball bearings, bearing lubrication is oil valley style, it
comes slinger for small shaft diameter.Special heat-insulating
cooling chamber for bearing suspension.
Working conditions This pump together with motor for indoor use or
outdoor use, class of explosion-proof and degree of protection
depends on the motor. Pump with same class of explosion-proof and
the degree of protection, please be sure to specify these
requirements at the time of ordering the product
