Product Description

Product Description

HBE liquid-ring vacuum pump is an energy-saving product developed by our company, and is used to pump gas which carries no solids undissolved or just slightly dissolved in wording liquid, to form vacuum and pressure in the closed container. The characteristics of this series product are as followings:

As the result of the flexible valve provided in the outlet to adjust the dischare angles, the pump can work efficiently at different suction condition.

Using an automatic discharge valve, the liquid level can be controlled well to prevent over-load start-up.

The rotating parts of the pump do not contact each other in the working chamber.Axial and radial load is borne by different bearings, being stable, safe and reliable.

There is observation hole on the side cover, pump's corrosive and scaling conditions can be observed through the hole, it is easy to maintain.

The working process is close to isothermal compression, particularly suitable for the delivery of flammable and explosive gases.

There are packing seal and mechanical seal  two kinds of structures to meet the needs of the different seals.

The impeller and shaft adopt thermal interference fit, with reliable preformance and smooth operation.

By changing materials of the wetted parts in contact with the medium, the pumps can transfer the corrosive gases or meet the anti-corrosion requirements underthe working condition with corrosive liquids as working fluid.

Pump Structure

 

PUMP SEAL

Packing seal is an economical and practical shaft seal way that pumps, especially large-sized ones, often, adopt.
There are two ways of cooling shaft seal, one of which is internal water supply way, another is external water supplyone.
Different cooling ways require different installing direction of the packing sleeve, so when the change of cooling way is needed, the direction of packing sleeve should be rotated, meanwhile, water supply way should be also changed. when external water supply way is adopted, pump should be connected with cooling water before operating.

 

Single mechanical seal prossesses the advantages of sealing reliability and long service life. Due to low sealing pressure, non-balanced mechanical seal is adopted, with compact structure. when single mechanical seal is used, the cooling way for shaft sealing adopts internal water supply, pump operates without external cooling water, and adopts self cooling way.

 

The goal to apply dual mechanical seal is to create an artificial environment in seal chamber to enable seal to operate without trouble for a long time. when toxic, volatile, combustible or explosive liquid is pumped. It is very necessary to create such an environment. An external reservoir with pressure must be used to supply clear isolating liquid which circulates in an internal cyclic loop or external flush system.
The pressure of isolating liquid should be greater than that of medium.
Dual mechanical seal can mate carious seal piping systems to make seal plans recommended by API682, for example typical seal plan 52,53 or 54.
