The key difference between such compressors and pumps is that the compressor working fluid is a gas (compressible) and the pump working fluid is liquid (incompressible). Centrifugal pumps basically consist of a stationary pump casing and an impeller mounted on a rotating shaft. A centrifugal pump is a mechanical device designed to move a fluid by means of the transfer of rotational energy from one or more driven rotors, called impellers. Almost every industrial centrifugal volute pump has an extremely short vaneless diffuser only upstream of the volute, compared to various diffuser types seen in centrifugal compressors. Liquid leaving the impeller at a high velocity enters the volute and has its velocity reduced causing a pressure rise. Please get in touch with us through WhatsApp. The chart given below lists the classification of pump base on API 610. diffuser ring centrifugal pump. Most commercial pumps have diverging (Figure A) channels called volutes cast into the discharge portion of the casing. The rotational energy typically comes from an engine or electric motor. The flow only reattaches to the wall after a travel path (L) equal to at least 8 to 10 times the diameter D 2. This is a ring fixed to the casing, around the impeller, in which there are passages formed by vanes. The flow only reattaches to the wall after a travel path (L) equal to at least 8 to 10 times the diameter D 2. In cases where this radial force results in excessive shaft deflection, a double volute design (Figure B) is used. To restore efficient, reliable operation and prevent catastrophic pump failure, it is critical to restore proper clearances between the stationary casing wear ring and the rotating impeller wear ring. Centrifugal pump Components vary in design and construction from simple pumps with relatively few parts to extremely complicated pumps with hundreds of individual parts. Wear rings play a crucial role in centrifugal pumps. 8. Some of the most common components found in centrifugal pumps are wearing rings, stuffing boxes, packing, and lantern rings. Under certain circumstances, a sudden transition from a small to a large pipe cross-section (e. g. a Carnot diffuser) may prove more advantageous than installing a diffuser, both for cost and hydraulic reasons. Change seal ring and diffusor sleeve if they damaged and influence pump. The casing must still function as a collector to convey the flow from the diffuser to the discharge nozzle. DESMI 56,035 views. A centrifugal pump typically features two adjacent wear rings: a stationary wear ring on the casing and a rotating wear ring on the impeller.
