Shenyang No. 1 Dg Medium Pressure Sub High Pressure Boiler Feed Water Centrifugal Pump

Product Description

use:
Performance Range: Flow (Q):7.****0m³h  Head (H): *******0m
Medium temperature: below **0 ° C
structure:
· DG type high-pressure boiler feed pump is a single-casing segment multi-stage centrifugal pump. The suction inlet and discharge outlet are vertical upwards. The middle section, inhalation and discharge section are connected into one body with a penetrating bar, and the stationary seal between each section. The surface is sealed with a metal surface and an O-ring is used as an auxiliary seal.
· Forging section, middle section and discharge section of DGB high-pressure boiler feed pump adopt forgings.
Shaft seal:
· The seal of DG type pump is sealed with soft packing and cooled with cooling water.
· Mechanical seals can be used according to user requirements.
Bearings and balancing devices:
· The pump rotor is supported by sliding bearings at both ends of the pump. The bearings are forced to lubricate and the pump itself is equipped with an oil system.
· The axial thrust of the rotor is balanced with a balance plate and has a thrust bearing. Used to withstand residual axial forces due to changes in operating conditions. A return pipe is installed between the balance chamber body and the suction pipe.
transmission:
· The pump is driven by an electric motor through a flexible coupling. It can also be equipped with a toothed coupling, a diaphragm coupling and a fluid coupling according to the user's needs. The prime mover can be driven by a small turbine or electric motor.
• The pump rotates clockwise when viewed from the drive.
material:
· Inhalation section, spout section, guide vane, impeller: carbon steel or chrome steel.
Shaft, seal ring, guide vane sleeve: Chrome vanadium steel or chrome steel.
