Product Description

High pressure horizontal multistage centrifugal pump for boiler water feeding

Product Description

General of High pressure horizontal multistage centrifugal pump for boiler water feeding

Model QD multi stages is a horizontal multistage centrifugal water feed boiler pump and suitable for transporting pure water (with the contained foreign matters' content less than l % and graininess less than 0. 1mm) and other liquids of both physical and chemical natures similar with those of pure water.

QD model middle and low pressure boiler water supply multistage pump is applicable to transport medium with temperature of not higher than 105℃, and is also applicable for small boiler water supply or transporting medium similar to hot water.

QDG model is used to transport medium with temperature of not higher than 160℃, and is also applicable for small boiler water supply or transporting medium similar to hot water.

Specification

Size: 25 - 450 mm
Flow: 3 - 684 m3/hr
Head: 15 - 680 m
Speed: 1450 - 2900 rpm

structure of High pressure horizontal multistage centrifugal pump for boiler water feeding

1. The QD series multi stages pump are sectional casing,multistage centrifugal pumps. The suction casing, stage casing and discharge casings are rigidly held together by tie bolts. The joints between these casings are primarily sealed by means of metal-metal contact. Simultaneously,O-rings are used as auxiliary seals.

2. The shafts of these pumps are sealed by soft-packing and cooling water. Mechanical seal can be used according to the client's requirement.

3. The rotating assembly is supported by sliding bearings on both ends of the pump shaft. Bearings of pump are forced-lubricated. The oil system is equipped for type QD(G) pump The axial thrust of rotor is balanced by balance disc. And the thrust bearing is also provided which is sed to bear residual axial force caused by the change of working conditions.

The assembly quality of the boiler pump will result in a notable affection to the performance and the running stability of it and can not be guaranteed unless the technical requirements in the drawings are strictly followed in the assembly, such as on the alignment between the centers of the impeller’s outlet and the guide vane's inlet. the uniform values of the sealing intervals of both rotor and stator portions etc.

Covering angle and central line posit ion adjustment. check the equipments at least in the fol lowing three periods and take adjustment:

The first time, both the multi stages pump and foundation are secured while the motor is not.

The second time, both pump and motor are secured while the bolts on the suck-in and spitting pipeline flanges are not.

The third time is in 24 hours after the pump starts running,then secure both pump and motor
