What is balancing drum in pump?
The balance drum is a device designed to balance axial thrust generated by impellers; it is usually combined with a thrust bearing which serves to compensate a small amount of residual axial thrust.
What is pump recirculation?
Recirculation in centrifugal pumps is a flow reversal at the inlet or at the discharge tips of the impeller vanes. Through analysis and tests, it is now possible to determine the flow patterns that must exist to produce the observed results.
What is meant by recirculation?
: the act or process of circulating again or causing something to circulate again … which help convert the steam generated within the reactor back into water for recirculation in the closed loop system.—
What is the purpose of recirculation?
Recirculation is the reintroduction of fluid into a cycle of circulation. It reduces the cost of operations and increases efficiency. Water recirculation is the processes of using the same water more than once in a system. The water must leave the system and re-enter it or be used in a different system.
What is recirculation factor?
In order to quantify the recirculation that exists in a confined system Wunning and Wunning [4] defined a parameter known as the recirculation factor (Kv), which is the ratio between the gas mass flow entrained by all jets , and the sum of air and fuel mass flows in the discharge.
What is water detention time?
The actual or theoretical (calculated) time required for water to fill a tank at a given flow; pass through a tank at a given flow; or remain in a settling basin, flocculating basin, rapid-mix chamber, or storage tank.
How does a detention tank work?
Detention tank: Detention tanks work by temporarily storing stormwater runoff during a rainfall event and then slowly releases the water into the public stormwater system. These can be located either above or below ground. Also known as a single purpose rain tank.
How much does a detention tank cost?
A 3000 litre Thin Tank costs $2200 excluding the costs of fitting it, and plumbing it in. Families in Auckland pay a single bill for water and wastewater to Watercare.
