Electric Vertical Multi Stage Pump For Conveying Clean Or Particle Containing Liquid

Product type-description:

　　VSD type petrochemical process pump is a centrifugal pump of vertical, single-stage or multi-stage, single or double suction, diversion shell type.It’s designed according to the API610 standard,VS1 type.This series of pumps is designed strictly in accordance with the standard in terms of pump support, bearing arrangement, reservation interface, cooling and washing, cavity structure etc.
This series of pumps has good hydraulic power,comprehensive spectrum,high efficiency and anti-cavitation.
According to different working conditions,VSD series pump is equipped with many kinds of structures,so that the best configuration achieves in all working conditions.Pumps with different configurations all have API standard seal chamber sizes, you can set different seal combination forms.

Parameters:

Standard:API610
Capacity:20~1600m3/h
Head: ~330m
Pressure:6.0MPa
Temperature:-80~250ºC
Application:this series of pumps is suitable for conveying clean or particle-containing, neutral or corrosive liquid such as oil refineries, power plants, steel factories, docks, water treatment, water supply, water supply and drainage system, seawater, river water, cooling water, sewage, crude oil etc.

Cross-section Diagram:

1.grease lubrication structure

1.Rolling bearing structure,grease lubrication, simple structure and good economy. Face to face angular contact ball bearings bears the residual axial force of the rotor.
2.Pump and motor adopt flexible connection. Small pump can also use rigid connection.The pump does not have separate bearing chamber and uses motor shaft to bear the axial force of the rotor.
3.Discharge casing equipped with mounting base has beautiful structure and reduces the number of pump parts.
4.API610 standard seal chamber size,and different seal and auxiliary systems can be configured according to requirements.
5.Safe and reliable connection of shaft is very good to ensure the accuracy of shaft, increases the insertion depth of shaft and expands the application range of the pump.
6.The shaft can be provided with a protective sleeve and flushed by external liquid,which guarantees a good operating environment for bushing and is suitable for particle-containing media.
7. Structure:seal rings in front and back cover board+balanced hole.This structure balances axial force and is reliable.
8.Delivery chamber is space guide blade structure, hydraulic design performance is stable and reliable,and small radial size reduces the overall installation space of the pump.
9.The impeller adopts advanced hydraulic model, and it has stable and reliable performance, high efficiency.First-stage can also use double-suction impeller.
10.Multi-supports bracing structure,;the sliding bearing spacing is in line with standard API610 requirements; high safety and reliability;bushings use wear-resistant rubber or compound materials.
11.The inlet is provided with a filter net to ensure that the pump is running in a relatively clean environment.

2.thin oil lubrication structure

1.Rolling bearing structure,thin oil lubrication, simple structure and good economy. Face to face angular contact ball bearings bears the residual axial force of the rotor.
2.Pump and motor adopt flexible connection. Small pump can also use rigid connection.The pump does not have separate bearing chamber and uses motor shaft to bear the axial force of the rotor.
3.Discharge casing equipped with mounting base has beautiful structure and reduces the number of pump parts.
4.API610 standard seal chamber size,and different seal and auxiliary systems can be configured according to requirements.
5.Balancing drum structure balances axial force and reduces the burden on the bearing;safe and reliable structure.
6.The shaft can be provided with a protective sleeve and flushed by external liquid,which guarantees a good operating environment for bushing and is suitable for particle-containing media.
7.Safe and reliable connection of shaft is very good to ensure the accuracy of shaft, increases the insertion depth of shaft and expands the application range of the pump.
8.Delivery chamber is space guide blade structure, hydraulic design performance is stable and reliable,and small radial size reduces the overall installation space of the pump.
9.The impeller adopts advanced hydraulic model, and it has stable and reliable performance, high efficiency.First-stage can also use double-suction impeller.
10.Multi-supports bracing structure,;the sliding bearing spacing is in line with standard API610 requirements; high safety and reliability;bushings use wear-resistant rubber or compound materials.
11.The inlet is provided with a filter net to ensure that the pump is running in a relatively clean environment.
