Figure 7: Parts of a Simple Seal Chamber
Seal chamber and Stuffing box both refer to a chamber, either integral with or separate from the pump case housing that forms the region between the shaft and casing where sealing media are installed. When the sealing is achieved by means of a mechanical seal, the chamber is commonly referred to as a Seal Chamber. When the sealing is achieved by means of packing, the chamber is referred to as a Stuffing Box. Both the seal chamber and the stuffing box have the primary function of protecting the pump against leakage at the point where the shaft passes out through the pump pressure casing. When the pressure at the bottom of the chamber is below atmospheric, it prevents air leakage into the pump. When the pressure is above atmospheric, the chambers prevent liquid leakage out of the pump. The seal chambers and stuffing boxes are also provided with cooling or heating arrangement for proper temperature control. Figure7depicts an externally mounted seal chamber and its parts.
Glands
The gland is a very important part of the seal chamber or the stuffing box. It gives the packings or the mechanical seal the desired fit on the shaft sleeve. It can be easily adjusted in axial direction. The gland comprises of the seal flush, quench, cooling, drain, and vent connection ports as per the standard codes like API 68
Throat Bushing
The bottom or inside end of the chamber is provided with a stationary device called throat bushing that forms a restrictive close clearance around the sleeve (or shaft) between the seal and the impeller.
Throttle Bushing
The throttle bushing refers to a device that forms a restrictive close clearance around the sleeve (or shaft) at the outboard end of a mechanical seal gland.
Internal Circulating Device
The internal circulating device refers to device located in the seal chamber to circulate seal chamber fluid through a cooler or barrier/buffer fluid reservoir. Usually it is referred to as a pumping ring.
Mechanical Seal
Mechanical seals will be discussed further in part two of this article series.
Bearing Housing

The bearing housing encloses the bearings mounted on the shaft. The bearings keep the shaft or rotor in correct alignment with the stationary parts under the action of radial and transverse loads. The bearing house also includes an oil reservoir for lubrication, constant level oiler, jacket for cooling by circulating cooling water.

light_speed_flow_max

Light plays a vital role in our everyday lives and technologies based on light are all around us. So we might expect that our understanding of light is pretty settled. But scientists have just uncovered a new fundamental property of light that gives new insight into the 150-year-old classical theory of electromagnetism and which could lead to applications manipulating light at the nanoscale.
It is unusual for a pure-theory physics paper to make it into the journal Science. So when one does, it’s worth a closer look. In the new study, researchers bring together one of physics' most venerable set of equations – those of James Clerk’s Maxwell’s famous theory of light – with one of the hot topics in modern solid-state physics: the quantum spin Hall effect and topological insulators.
To understand what the fuss is about, let’s first consider the behaviour of electrons in the quantum spin Hall effect. Electrons possess an intrinsic spin as if they were tiny spinning-tops, constantly rotating about their axis. This spin is a quantum-mechanical property, however, and special rules apply – the electron has only two options open to it: it can either spin clockwise or anticlockwise (conventionally called spin-up or spin-down), but the magnitude of the spin is always fixed.
In certain materials, the spin of the electron can have a big effect on the way electrons move. This effect is called “spin-orbit coupling” and we can get an idea of how it works with a footballing analogy. By hitting a freekick with spin, a footballer can make the ball deviate to the left or the right as it travels through the air. The direction of the movement depends on which way the ball is spinning.
football_rotation_two_players_playing


Spin-orbit coupling causes electrons to experience an analogous spin-dependent deflection as they travel, although the effect arises not from the Magnus effect as in the case for the football, but from electric fields within the material.
A normal electrical current consists of an equal mixture of moving spin-up and spin-down electrons. Due to the spin-orbit effect, spin-up electrons will be deflected one way, while spin-down electrons will be deflected the other. Eventually the deflected electrons will reach the edges of the material and be able to travel no further. The spin-orbit coupling thus leads to an accumulation of electrons with different spins on opposite sides of the sample.
This effect is known as the classical spin Hall effect, and quantum mechanics adds a dramatic twist on top. The quantum-mechanical wave nature of the travelling electrons organises them into neat channels along the edges of the sample. In the bulk of the material, there is no net spin. But at each edge, there form exactly two electron-carrying channels, one for spin-up electrons and one for spin-down. These edge channels possess a further remarkable property: the electrons that move in them are impervious to the disorder and imperfections that usually cause resistance and energy loss.
This precise ordering of the electrons into spin-separated, perfectly conducting channels is known as the quantum spin Hall effect, which is a classic example of a “topological insulator”– a material that is an electrical insulator on the inside but that can conduct electricity on its surface. Such materials represent a fundamentally distinct organisation of matter and promise much in the way of spintronic applications. Read heads of hard drives based on this technology are currently used in industry.
Beginning to see the light
Now, the new study suggests that the seeds of this seemingly exotic quantum spin Hall effect are actually all around us. And it is not to electrons that we should look to find them, but rather to light itself.
In modern physics, matter can be described either as a wave or a particle. In Maxwell’s theory, light is an electromagnetic wave. This means it travels as a synchronised oscillation of electric and magnetic fields. By considering the way in which these fields rotate as the wave propagates, the researchers were able to define a property of the wave, the “transverse spin”, that plays the role of the electron spin in the quantum spin Hall effect.
In a homogeneous medium, like air, this spin is exactly zero. However, at the interface between two media (air and gold, for example), the character of the waves change dramatically and a transverse spin develops. Furthermore, the direction of this spin is precisely locked to the direction of travel of the light wave at the interface. Thus, when viewed in the correct way, we see that the basic topological ingredients of the quantum spin Hall effect that we know for electrons are shared by light waves.
This is important because there has been an array of high-profile experiments demonstrating coupling between the spin of light and its direction of propagation at surfaces. This new work gives a integrative interpretation of these experiments as revealing light’s intrinsic quantum spin Hall effect. It also points to a certain universality in the behaviour of waves at surfaces, be they quantum-mechanical electron waves or Maxwell’s classical waves of light.
Harnessing the spin-orbit effect will open new possibilities for controlling light at the nanoscale. Optical connections, for example, are seen as a way of increasing computer performance, and in this context, the spin-orbit effect could be used to rapidly reroute optical signals based on their spin. With applications proposed in optical communications, metrology, and quantum information processing, it will be interesting to see how the impact of this new twist on an old theory unfolds.
