Overview
The pumps are horizontal, single-stage, single-suction, cantilevered and centrally supported centrifugal pumps. The design standards are API 610 and GB3215. API code is OH2.KOH has a conventional design with closed impeller, while KOK is an open impeller design. Pumps can be applied in the transportation of most process medium because of extensive performance range. extremely sophisticated design and a variety of constructions.
Pipeline Auxiliary System
All pipeline systems are designed to the standard of APl610 (the 1Othedition). According to working conditions, pump bonnet, bearing bracket and pump support may be cooled, and seal gland maybe back quenched. To handle easily crystallized and solidified media, pump casing and bonnet maybe heat traced, The flow rate of cooling water for each pipeline: 0.3-0.6m’/h for pump bonnet, bearing bracket and pump casing respectively; 0.06m’/h for the quenching of seal gland.
Seal flush differs from the temperature and pressure of medium handled The sealing liquid of each chamber stated in the table below (applicable for internal or external supply).
Seal flush schemes depend on specific working conditions. Typical pipeline flushing system including:
Single seal self-flushing, used in the medium handled being clear liquid or liquid containing a few impurities, To handle liquid containing solid particles, cyclone hydraulic separator shall be connected in, To handle medium of high temperature, heat exchanger shall be connected in. This type of flushing scheme requires the allowable pressure of seal higher than the discharge pressure of pump.
Single seal external flushing, in which seal flush liquid will be mixed into the medium to be pumped. When the medium pumped is in disadvantaged conditions (poor lubricity or containing a mass of impurities)and when the medium pumped allows external liquid to be mixed in, this scheme can be adopted. But the pressure of external liquid shall be higher than the pressure of sealing chamber) This scheme can be used in the. Dual seal external flushing conditions where the medium pumped cannot be used as seal flushing liquicdue to its poor performance, and where medium disallows any other media to be mixed in, It can be flushed directly by pressured liquid source, or by the limited medium in the circulating pressure vessel of pump or seal.
