HLB (K) series vertical long shaft oblique flow turbopump

overview

HLB (K) series HLB, HLBK, HLKS, HLKT single shell vertical long shaft oblique flow turbopump systemVertical single-stage guide vane mixed flow cantilever centrifugal pumpThe vertical single-stage (multi-stage) centrifugal or inclined flow turbine pump with guide vane structure is a vertical suspension turbine pump product developed by our factory by drawing on international advanced technology and combining it with China's actual situation, complementing each other's strengths and weaknesses. Supply and transport clean water, rainwater, seawater, and sewage with a temperature below 55 ℃. Suitable for use as a circulating pump in power plants, it can also be used as industrial water for steel plants, shipyards, urban water supply, drainage engineering, and agricultural irrigation.

Structural characteristics of HLB (K) series vertical long shaft oblique flow turbopump

1. Installation method

Single layer foundation: The motor and pump are directly installed on the same foundation layer, and the pump outlet can be arranged below or above the foundation layer.

Double layer foundation: The motor and pump are installed on their respective foundation layers, and the pump outlet is located between the two foundation layers.

The installation types of pumps include wet pit installation or dry pit installation.

Wet pit installation: The lower part of the pump is submerged in the suction tank.

Dry pit installation: The pump adopts pipeline inlet, and the pump suction horn mouth is connected to the inlet pipeline with a 90 ° elbow shaped inlet bend.

2. Pumps are divided into three types: non withdrawable, rotor withdrawable (including guide vanes), or pump integral withdrawable. When the pump diameter is below 1000mm, the pump rotor is generally non withdrawable; When the pump diameter is above 1000mm, the pump rotor is generally in a withdrawable form.

3. Pump impellers are divided into integral impellers or combined impellers.

4. The axial force of the pump is borne by the thrust bearing of the motor or the thrust bearing of the pump. When the pump diameter is below 1000mm, the axial water thrust and rotor weight of the pump are generally borne by the thrust bearing of the pump body, and an elastic connection is used between the pump and the motor. When the pump diameter is above 1000mm, the axial water thrust and rotor weight of the pump are generally borne by the thrust bearing of the motor, and a rigid connection is used between the pump and the motor; When the pump body is subjected to axial water thrust and rotor weight, the pump thrust bearing adopts thin oil lubrication, and the thrust bearing components are equipped with Pt100 temperature measuring elements to measure the bearing temperature or pressure type thermometers to measure the lubricating oil temperature.

5. The bearings of the pump are rubber (wear-resistant, corrosion-resistant, seawater resistant rubber) guide bearings and Sailong bearings. The pump shaft is usually equipped with a protective tube, which is filled with clean pressure water for lubrication and flushing of the guide bearing. The water volume can be controlled by a flow relay to prevent damage to the bearing due to water shortage. When the pump is used to transport sewage or water containing particles, the end of the guide bearing in the guide vane body is equipped with a parking automatic shaft seal device to prevent the medium from entering the bearing after shutdown; Lubrication forms include external lubrication water and pump self lubrication.

6. In addition to using materials that are resistant to seawater corrosion, pumps that transport seawater also use sacrificial anode and external power source cathodic protection devices to prevent electrochemical corrosion of pump components.

7. The pump is directly driven by a motor through a rigid or elastic coupling.

8. There are two types of pump suction ports: the usual horn shaped or the improved elliptical guide pier.
