2.1  Whole structure:

The Vertical Turbine Generators Pump is a vertical double deck shell structure, and the single base is installed. For the single suction impeller or double suction impeller as a secondary form, single suction form. The suction port of the water pump can be positioned under the foundation or on the base layer, and the outlet is arranged on the foundation, and the two can be arranged at an angle of 90 DEG, 180 DEG, etc.. The inner shell part can be drawn out for maintenance and overhaul.

The axial thrust of the pump and the weight of the rotor are carried by the pump body, and the pump and the motor are connected by an elastic coupling.

From the end of the motor, the pump rotates counter clockwise.

2.2.1  Outer cylinder

The outer cylinder is a round cylindrical part welded by a high quality carbon steel plate or stainless steel plate. When the suction port is below the base layer, the suction port is opened on the outer cylinder. The outer cylinder is the outer pressure chamber of the pump, and the liquid can be stably introduced into the suction bell mouth. When the normal temperature pump works, the cavity is in a vacuum state, and the cavity is in a positive pressure state when the high temperature pump works.

2.2.2  Pump rotor

The pump rotor is the core part of the pump, impeller, pump shaft, shaft sleeve, sleeve, keys and other parts, the increase of imports of impeller flow area to improve the anti cavitation performance of the pump.

Impeller: the impeller converts the mechanical energy of the prime mover into water by rotating it at high speed.

Pump shaft: the main transmission torque, coupled with the motor through the flexible coupling.

The pump shaft and impeller are connected by a key and a round nut, and the key transfers the torque, and the round nut is positioned in an axial direction.

The pump shaft and the pump shaft are connected by a sleeve coupling, and the utility model has the advantages of good neutrality and convenient assembly and disassembly.

 2.2.3  Suction bell

The suction bell outer cylinder in water evenly and stably into the impeller, is arranged inside the guide bearing chamber is connected by ribs. Guide bearing, impeller sealing ring is installed on the suction bell inside. The suction bell is connected with the inlet section by the stud nut.

2.2.4  Guide vane

The function of the guide vane is to change the kinetic energy of the liquid into the pressure energy and guide the liquid flowing out of the impeller into the lower impeller or the outlet section with the minimum loss. The guide vane is sheathed on the guide blades.

2.2.5  Middle part

The guide vanes are arranged in the middle section, and each middle section is positioned by a stopper, and is fastened with the water inlet section and the water outlet section through the bar. Each secondary impeller seal ring is installed in the part, and the middle part of the lug boss prevents the guide vane from rotating.

2.2.6  Effluent section and lifting pipe

The liquid in the pump is drawn out uniformly, and the guide bearing is installed in it.

2.2.7 Curved   pipe

The water outlet pipe is welded by the straight pipe section, the transverse pipe section and the supporting plate, etc. when the suction port is above the base layer, the suction port is opened on the water outlet bent pipe, and the main shaft passes through the center of the part. The liquid flowing from the suction pipe passes through the part and enters the pump outside the pressure pipe horizontally. A gas discharge opening is arranged on the water outlet elbow so as to discharge the gas in the outer cylinder into the condenser or the pump body. The motor seat is installed on the water outlet bend pipe, and the shaft seal part and the balance device are installed in the water outlet bent pipe.

2.2.8 Guide bearing

The guide bearing plays the role of supporting the pump shaft in a radial direction, and the lubricating fluid is the liquid of the pump itself.

2.2.9  Mechanical seal parts

The water pump can be made of a container type mechanical seal, the machine seal is connected with the machine sealing body, and the flushing water needs to be connected, and the water source can be connected with the cooling water, and can also be extracted from the pump out of the jellyfish tube.

2.2.10 Thrust bearing parts

The water pump with deep groove ball bearings and thrust roller bearing residual axial force, oil lubrication, cooling pipe external can also leads to cooling water cooling water pipe from the pump, the rotor with the adjusting nut to adjust thrust bearing parts in ascension.

2.2.11  Coupling parts

The two shafts of the pump are connected by a sleeve coupling, and the elastic coupling is used between the rotor of the pump and the motor.
