Power plant boiler hot water circulation pump

Product Description

Description of Power plant boiler hot water circulation pump

There are two type of multistage water pump we supply, horizontal multistage pump and vertical multistage pump, centrifugal theory, meet require of high pressure feeding water, high efficiency low noise make it to be the greatest choice in suppling water system. Moreover, high pressure performance make it works well in fire system, mining dewatering, agriculture irrigation, boiler feeding water.

Power plant boiler hot water circulation pump structure specification

The basic structure of multistage pump is composed of six parts, respectively, the impeller, pump, shaft, bearings, seal rings, stuffing box.

Impeller: it is a core part of multistage pump, smooth inner and outer surface help to reduce the flow friction loss, and play crucial roles in pumping water at very high pressure.

Casing:

it is a body of multistage water pump, tplay a role of supporting & fastening, and connected to the bracket whitch mounting the bearing.

Pump Shaft:

It is the main components of the mechanical energy transfer.

Shaft Bearing:

it is a component to support the shaft, there are two kinds of rolling bearing and Sliding bearings. Rolling bearing use butter as a lubricant oil, Sliding bearings using a transparent oil as a lubricant.

Sealing ring:

use to increase the resistance of back-flow, and reduce internal leakageAlso known as leakage reduction ring, by this way, it is helpful for Increase the service life of the impeller and casing.

Stuffing Box:

Composed of packing, seal loop, packing tube, packing gland, seal tube. Keep pump in vacuum state when working.
