Entering into the mixed cylinder, the end of the primary net water supply line is connect with one end of primary net water supply line elbow,
The other end of the primary net water supply line elbow with once connect for straight section central tube, the primary net water supply line insert
It is in the same direction with secondary network return water water (flow) direction by the primary net water supply line elbow steering after entering into the mixed cylinder,
Described is primary concentric for straight section central tube and the mixed cylinder.
The straight mixed thermal power plant unit mixer and pump inlet fluidic device, the primary net water return pipeline is described
Mixed cylinder left vertical is inserted into the mixed cylinder, the end of the primary net water return pipeline and primary net water return pipeline
Elbow connection, the primary net water return pipeline elbow steering is reverse with secondary network return water water (flow) direction, and described once nets back
Waterpipe elbow and the mixed cylinder are concentric.
The described straight mixed thermal power plant unit mixer and pump inlet fluidic device, the left side of the mixed cylinder by variable diameter with
The right side of the connection of secondary network water return pipeline, the mixed cylinder is mixed by the variable diameter and flange with the efficient decontamination
Heat exchanger connection.
The straight mixed thermal power plant unit mixer and pump inlet fluidic device, the other end of the primary net water supply line
It is connect with the primary net booster pump, the center line position of the primary net pressurization pump intake, which introduces, the confession of secondary network high pressure
Water-jet flow tube is equipped with ball valve on the secondary network high service jet pipe.
The utility model beneficial effect achieved is:
1. the primary net water supply line of the utility model is inserted perpendicularly into mixed cylinder, pass through primary net water supply line elbow after insertion
Steering is in the same direction with secondary network return water water (flow) direction, increases after elbow and once (purpose: increases flow velocity and balanced stream for straight section central tube
Region), it is once concentric for straight section central tube and mixed cylinder.When secondary network water flows through once for straight section central tube, according to literary mound
In effect (low pressure can be generated near swiftly flowing fluid, to generate suction-operated), be conducive to primary net water by one
It is secondary to enter mixed cylinder mixing for straight section central tube.The lift for reducing primary net booster pump plays the role of saving electric energy.
2. the primary net water return pipeline 13 of the utility model is inserted into mixed cylinder in mixed cylinder left vertical, pass through one after insertion
Secondary net water return pipeline elbow steering is reverse with secondary network return water water (flow) direction, and primary net water return pipeline elbow and mixed cylinder are concentric.
Due to inserting primary net confession, return pipe road at mixed cylinder center, the circulation area at this position can reduce, therefore in this position two sides
By variable diameter overstriking, increase circulation area.
3. the utility model introduces secondary network high service at primary net pressurization pump intake faces toward pump center line of suction position
Jet pipe is equipped with ball valve on secondary network high service jet pipe, for adjusting flow.According to Venturi effect (in high velocity stream
Dynamic fluid nearby can generate low pressure, to generate suction-operated), be conducive to improve in the pressure of primary net pressurization pump intake,
Slow down cavitation phenomenons of the primary net pressurization pump intake under low pressure, the condition of high temperature.
