Problems solved by technology

But the result is that the structure of the device is more complicated and the energy recovery efficiency cannot be guaranteed
The best way is to use movable guide vanes to adjust the working conditions, but the design of the movable guide vanes is various, but it is difficult to match the pump or energy recovery device for structural design. The current published patents only disclose the form, but it is difficult to specify Specific application of pump devices

Abstract

The invention belongs to the technical field of fluid machines, and relates to a rotation guide vane module for hydraulic power work condition adjustment and an assembling method of the rotation guidevane module in a turbine pump. The rotation guide vane module comprises a rotation guide vane rear cover plate, a rotation guide vane front cover plate, a rotation guide vane drive gear and rotationguide vanes. The rotation guide vanes are integrally-formed independent components and each comprises a rotation guide vane rear base, a blade, a rotation guide vane front base and a shaft. When the rotation guide vane module is used for adjustment, a center gear rotates, the rotation guide vane drive gear is driven, the guide vanes rotate, and accordingly the aperture of the guide vanes is changed. According to the provided technical scheme, the rotation guide vane module can be applied to reverse osmosis sea water desalination and other systems, work condition adjustment can be conducted under the situation that devices are not replaced, and the efficient area range under the multi-work-condition application condition can be widened.

Description

Technical field [0001] The invention belongs to the technical field of fluid machinery. Specifically, it relates to a hydraulic operating condition regulating rotary guide vane module and an assembly method thereof in a turbo pump. Background technique [0002] Pump and turbine, or a combination of both turbine and pump (turbine pump for short) is an indispensable device in the industry that pressurizes the medium or recovers energy. The structure of the existing device has a certain degree of adjustment to working conditions. Due to its limitations, different types and specifications of equipment are often required to meet the requirements of different working conditions. [0003] Turbine pumps combine pumps with energy recovery devices and are often used in reverse osmosis seawater desalination systems. However, the system's requirements for seawater desalination recovery rate are not static, so higher working condition adjustment requirements are put forward for such pumps and ...
