First, an overview

KHB type stainless steel food biochemical process pump and KHB in high temperature resistant corrosion centrifugal pump is the company to digest introduction of Swedish Allah cutting advanced technology, independently developed with independent intellectual property rights of products, in the domestic has the leading level.

KHB type pump with auxiliary impeller dynamic seal, mechanical seal with, especially for contained in the transmission of a certain concentration of solid particles suspension, due to the role of vice impeller, reduce the sealing cavity solid particles concentration, improves the working environment of mechanical seals, thus enhancing the mechanical and the service life of the sealing.

Two, the scope of application

KHB type pump is especially suitable for containing a certain amount of solids biological products suspended liquid medium to transport, or strong corrosive liquid medium.

Mainly used:

Biomass energy device with pumps, such as starch, starch sugar, glutamic acid, lysine amino acid, citric acid, alcohol (ethanol, propylene ammonia alcohol) etc. Department pumps used in petroleum refining, oil transportation device, oil processing device pump.

Pump for water supply and seawater desalination system.

Sewage treatment, environmental protection system with the pump.

Coal chemical pump.

Three, the use of parameters

Flow range: 12.5~1000m range: 8~260m /h fand head

Working pressure: 0.02~2.5MPa medium temperature: CHB type -1.-0 type KHB is -40 DEG ~120 DEG ~260 DEG C

Four, structural characteristics

KHB type pump is a single-stage single suction cantilever centrifugal pump, horizontal axial suction center vertical discharge. Using the structure after the door form, its characteristics is convenient for maintenance, in on pump solution physical repair, without removing the pump suction and discharge piping flange, can replace the pump impeller, a sealing ring, mechanical seal, bearings and other components.

KHB peripheral water-cooled cavity seal, bearings, suspension parts, also did not choose the water-cooled jacket and is therefore particularly suitable for conveying high temperature (- 40 DEG C c-260deg C) liquid medium.

Bearing suspension components using radial thrust ball bearings two sets of back-to-back to balance the residual axial force, thin oil lubricating oil tank.

Pump bearing to a force balance approach there are two, one is by the Deputy leaves, another is on the balance hole. Due to the effect of auxiliary impeller, can reduce pressure seal cavity, and reduce the sealing the concentration of solid particles, improves the service life of the mechanical seal.

Pump hydraulic design of advanced, high efficiency and energy saving, large flow pump and the double volute design balanced radial force, pump running smoothly, improve the running reliability of the pump.

The hydraulic design of the pump shaft meets the design requirements of the AP1610 rigid shaft

Pump steering: from the motor side, it appears that the pump rotates clockwise.
