Radial flow steam turbine (High speed, high efficiency, various condition, energy saving)

The enthalpy of radial flow steam turbine is one time higher than axial flow steam turbine, then there are only 1~3 stage. The rotor is with long and narrow blade. The unit is designed with high speed, then output power 15%~50% higher than axial flow steam turbine. And if power is same, the efficiency can be up to 62%~77%, normally only 30%~60%, and maybe 84%. The unit features small volume, tight structure, high efficiency, easy maintenance. It is used well to drive high speed equipment or generator. Since 2006, we have got 3 invention patents and utility model patent.

Hydraulic turbine

Hydraulic turbine can convert the energy in fluid to mechanical drive energy. In petrochemical device, there are much potential energy when the high pressure liquid transferred to low pressure device, which can be recovered by hydraulic turbine. It is used extensively in high pressure liquid to recover the energy. 

HTDB Double-Casing Self-balance High- temperature High-pressure Centrifugal Pump

HTDB Double-Casing Self-balance High-temperature High-pressure Centrifugal Pump, designed according to API610 standard, is a kind of efficient energy-saver Self-balance high-temperature high-pressure centrifugal pump, whose outer casing adopts the cylinder structure and the radial-split design and inner casing uses the axially horizontal split Structure. The pump is characteristic of long operating life, high reliability, easy maintenance and low maintenance cost. The pump is mainly used in pumping the high-pressure liquid ammonia in the chemical fertilizer plant and the high temperature, neutral or corrosive, and clean liquid in the fields of boiler feed water, hydrogenation feed, oilfield high-pressure water injection, petrochemical process and so on.
