Components of Mechanical Seal

-

There are various types of Mechanical Seal, assembly gets more complicated as the application become critical.

The basic components of a mechanical seal are a Rotating Part and a Stationary Part. 

Following Diagram show the cross section of the Simplest Mechanical Seal :

Impeller Selection

-
Image
  The specific speed of centrifugal pump is defined as speed of geometrical Similar pump which would deliver one cubic meter of liquid per second against head of one meter It is a function of shaft speed, flow rate, and differential head at the pump Best Efficiency Point  Sp.Speed It is a key consideration in the design and selection of pumps, and particularly pump impellers , is specific speed.

Advantages & Disadvantages of Mechanical Seals

-
Image
 Advantages Reduced Friction And Loss of Power Negligible Product Leakage Elimination Of Excessive Wear Maintenance Reduced Long Term Cost Effectiveness Disadvantages Less tolerant to shaft deflection and misalignment  High beginning expense The structure is relatively complex Require workers to have a certain level of installation skills. Less tolerant to dirty or contaminated liquid, Require expensive seal piping to flush and quench                               Causes of the Pump Failures     Mechanical seal failure - 60 to 70% Bearings failure- 15 to 25% Pumping rate 5 to 10% Miscellaneous 5 to 15%

Volute casing & Impeller

-
Image
  Volute of a centrifugal pump is the casing that receives the fluid being pumped by the impeller As liquid exits the impeller it has high kinetic energy and the volute directs this flow through to the discharge.  As the fluid travels along the volute it is joined by more and more fluid exiting the impeller but, as the cross sectional area of the volute increases, and velocity is gradually reduces. Volute casings come in three different types:  Single volute and Double volute The fundamental benefit of a double volute over a single volute is the equalization of the pressure distribution within the volute. Radial thrust can substantially increase the pump shaft deflection Pressure distribution comparison  for non diffuser volute casing The motional energy of one or more driven rotors, known as impellers, is transferred to power a centrifugal pump.  The fluid is...
