Head H : 38～280m

Temperature T : -80～+450°C

Applications

Petrochemical industry Power station

Coalindustry Chemical industry

Features

Pump casing: the double-volute structure reduces the radial thrust, the fluid that entering into impeller will be distributed evenly and symmetry. The suction and drain on casing, without dismantling the pipeline to replace the wear parts and rotor parts

Pump cover : the symmetry double pump cover structure, it is easily for maintains, The cooling chamber which could decrease the working temperature in seal chamber, which guarantees seal long running and reliability.

Impeller: the double suction impeller would automatic balance the axial force of rotor, which decrease the NPSHr.

Shaft: the rigidity Shaft designing could guarantee the pump running steadily under the working speed. The heavy-duty shaft is designed for adopting the suitable bearing span, which supplies the reliability and anti-turn safety, it is easily assembly when using the taper extended shaft.

The bearing: the equipped diagonal contacting ball bearing that would guarantee the load capacity in heavy duty. There are air cooling(t<120 °C), wind cooling (t=120°C-260°C) and water cooling (t=260°C-450 °C), which will decrease the bearing working temperature to improve the bearing life.

The seal and auxiliary system: completely according to the API682 with flushing pipeline and cooling system.

Type Meaning

SOY 150 - 125 B

SOY: Single stage double suction centrifugal oil pumps with between bearings

150: Suction diameter of pump (m)

125: Head (m)

B: Indication of impeller correction, the second correction

Overview

Series SBR is a horizontal between bearings radially-split double-volute single-, two- or three-stage centrifugal pump. Two hydraulic powers of high efficiency and anti-cavitation can be selected for the impeller depending on the operation condition so that it can be used for a broader range of operation conditions.

Series HR pumps comply with the design requirements in API 61010th and API 61011th. The product was designed by reference with the design and hydraulic performance of the most excellent similar products at home and abroad and by use of the advanced hydraulic power and strength analysis software. The strict international quality control system was applied in the process control of product to ensure that the overall performance of the product reaches the China-leading and world-advanced level.

Application range

Widely used for recovering excessive hydraulic pressure energy from petroleum refining, petrochemical, CTL, coal chemical, natural gas processing, polycrystalline silicon, platforming, heating and other plants. Typically used as hydraulic desulfurization and decarburization turbines in synthetic ammonia plants, hydraulic hydrogenation turbines in petroleum refining plants, hydraulic circulating water recovery turbines in polycrystalline silicon plants, turbine expansion engines in liquefied natural gas stations, hydraulic high-pressure water recovery turbines in sea water desalinization, etc.

Materials

Main materials: S-5, S-6, S-8, C-6, A-7, A-8, D-1, D-2 and other materials to API610, or designed according to the requirement of the customers.

Sealing

The sealing system designed completely according to API 682 Standard 3rd Edition "Pumps-Shaft Sealing Systems for Centrifugal and Rotary Pumps" can be configured with different types of seals and seal flushing and cooling modes, or as required by the customer.

Technical

◎ Capacity Q: 20 ~ 4500 m3/h

◎ Head H: ~ 660 m

◎ Pressure P: 5, 10, 15 MPa

◎ Temperature T: -80℃ ~ +450℃

Direction of rotation

In section of hydraulic turbines, the direction of rotation can be selected according to the setting of drive units.

Configurations

There are three typical configurations for the unit, as below:

Turbine + pump

Turbine + clutch + motor + pump

Turbine + clutch + motor + gearbox + pump

Technical innovation on the unit:

Turbine + asynchronous motor + current processor

The innovative technology makes the turbine directly drive the asynchronous motor to generate electricity and ensure that the electricity quality meets the state's requirement for grid electricity so that the field operation, unit arrangement and energy recovery are optimized.

Key technologies

The technology for solving the axial and radial forces of a large amount of gas onto the rotor as the hydraulic energy is being relieved, the lubrication and other problems.

The technology for ensuring the turbine stability upon fluctuation of the unit pressure.

The overspeed protection technology for hydraulic turbine.

The technology of clutch selection.

The technology for rationally configuring and completing the unit.

The reliable and safe field commission technology.
