I would like to know about vacuum pump design

[@mohamedrakeebmohamedzuhar9321]

Please explane primary Secondnary pump

[@anilpal5947]

Any one tell me , how much should clearance between impeller and casing

[@santoshpatnaik30]

Sir why balancing line and recirculation line for multistage pump???

[@Coreengineers]

Balancing and recirculation lines are provided in multiple stage pumps to ensure proper hydraulic balance between the stages and to prevent overheating or excessive wear on the pump components. Balancing lines are used to equalize pressure between stages, ensuring that each stage of the pump operates efficiently and evenly. This helps to prevent uneven loading and premature wear on the pump components. Recirculation lines, on the other hand, allow a portion of the discharge flow to be recirculated back to the suction side of the pump. This helps to maintain adequate flow through the pump during low flow conditions, preventing issues such as cavitation and overheating. Overall, these features help to improve the performance, reliability, and longevity of multiple stage pumps. I hope you got the answer of your query.

Sir what is difference between high flowrate and high head??in pump?

[@Coreengineers]

a pump with a high flow rate moves a lot of fluid quickly, while a pump with a high head generates significant pressure to push fluid through a system, even against resistance.

Sir why vaccum creation required for pump???

[@Coreengineers]

Where have you seen this phenomenon?

[@chellamsiva8030]

creating vaccum at suction side enables the fluid to flow into pump through the eye of impeller

Sir what is turbine vertical pump???what r the main components??

[@Coreengineers]

A turbine vertical pump is a type of centrifugal pump designed specifically for applications where high flow rates and high heads are required. It consists of multiple stages, typically enclosed within a vertical casing, with each stage comprising a rotating impeller and a stationary diffuser or guide vane. Main components: Turbine vertical pump components: Shaft, impellers, diffusers, casing, bearings, sealing, inlet/outlet. Convert mechanical energy to fluid movement efficiently. I hope you got the answer of your question!

Sir what is thermal shock??

[@Coreengineers]

Thermal shock in centrifugal pumps occurs when there is a rapid and significant change in temperature within the pump components. This sudden temperature variation can lead to the expansion or contraction of materials at different rates, causing stress, distortion, and potential damage to the pump.
