Inlet ports

Some attempts have been made to reslurry the filter cake without having to open the filter press. However, a number of problems appear, eg, bending of the plates due to uneven cake deposition or cavitation, uneven dewatering and washing within the frames, and plugging of the inlet ports.

Compression is achieved by the intermeshing of the male and female rotor. Power is applied to the male rotor and as a lobe of the male rotor starts to move out of mesh with the female rotor a void is created and gas is taken in at the inlet port (see Figure 4-2). As the rotor continues to turn, the intermesh space is increased and gas continues to flow into the... 

Straight-lobe compressors, or blowers, as they are commonly called are low-pressure machines. The feature unique to these compressors is that the machines do not compress the gas internally as do most of the other rotaries. The straight-lobe compressor uses two rotors that intermesh as they rotate (see Figure 1-7). The rotors are timed by a set of gears. The lobe shape is either an involute or cyclodial form. A rotor may have either two or three lobes. As the rotors turn and pass the inlet port, a volume of gas is trapped and carried between the lobes and the outer... 

Inlet port injection is used with liquid fuel, spark ignition engines only. Fuel is injected into the inlet port and mixed with the inlet iii The injection process may be either timed or continuous. 

Figure 4-78. Tubular in-line pressure filter with reusable elements. The flow unfiltered liquid enters the inlet port, flows upward, around, and through the media, which is a stainless steel or fabric screen reinforced by a perforated stainless steel backing. Filtered liquid disch lrges through the outlet (top) port. Because of outside-to-lnside flow path, solids collect on the outside of the element so screens are easy to clean.

Cyclical opening and closing of the inlet and discharge ports occurs by the rotor s vanes passing over them. The inlet port is normally a wide opening that is designed to admit gas in the pocket between two vanes. The port closes momentarily when the second vane of each air-containing pocket passes over the inlet port. 

A pump must have a continuous supply of fluid available to its inlet port before it can supply fluid to the system. As the pump forces fluid through the outlet port, a partial vacuum or low-pressure area is created at the inlet port. When the pressure at the inlet port of the pump is lower than the atmospheric pressure, the atmospheric pressure acting on the fluid in the reservoir must force the fluid into the pump s inlet. This is called a suction lift condition. 

There are outlet ports in the manifold to provide connections to each subsystem. A similar manifold may be used in the return system. Lines from the control valves of the subsystem connect to the inlet ports of the manifold, where the fluid combines into one outlet line to the reservoir. Some manifolds are equipped with check valves, relief valves, filters and so on, required for the system. In some cases, the control valves are mounted on the manifold in such a manner that ports of the valves are connected directly to the manifold. 

A simple manifold is illustrated in Figure 40.41. This manifold contains one pressure inlet port and several pressure outlet ports that can be blocked off with threaded plugs. This type of manifold can be adapted to systems containing various numbers of subsystems. A thermal relief valve may be incorporated in this manifold. In this case, the port labeled T is connected to the return line to provide a passage for the relieved fluid to flow to the reservoir.

Non-return valves are essential in the operation of pumps. It is important to ensure that when the pump compresses the solvent, it leaves at the exit port and is completely arrested at the inlet port. Conversely when the pump draws fresh solvent into the cylinder, the non-retum valves must allow solvent to flow through the inlet valve, but flow-back from the other side of the exit valve must be...

The chip comprises five inlet ports and two outlet ports [28]. Three streams, two aqueous phases and one organic phase, are contacted initially a layered system is created in this way (Figure 4.13). The aqueous phase is removed from the main stream two other aqueous streams encompass the remaining organic phase. The two streams fulfil different functions. In total, several (up to 10) chemical unit operations may be conducted in series in this way. 

This micro-chip reactor comprises a liquid inlet port which splits into two channels of equal passage [21]. These split channels merge with a third channel, which is connected to a second port for gas feed, in such way that the two liquid streams encompass the gas stream. This triple-stream feed section is followed by a long serpentine channel passage which ends in a third outlet port (Figure 5.11).
