Types & Parts Of Ropeway

Ropeway is a mode of transport that has a capacity to bear heavy weights of passengers and provides them a safe and comfortable ride. However, it can also used to carry materials, goods and components. It is engineered of stainless steel overhead cables attached to the poles from which ropeway carriers are supported. Ropeway is of two types; bio cable and mono cable ropeway. A bi-cable tower consist of  saddles and roller battery, while a mono-cable tower has only roller battery to support the hauling-carrying rope.

The capacity of Ropeway can be measured by the factors like load, it can carry per hour, speed of the carriers, number of passengers.

TYPES OF ROPEWAYS:-
1) Bicable (2S) & Tricable (3S) Gondola lifts
2) AERIAL TRAMWAYS
3) Inclined elevators
4) Fixed Grip Chairlifts.

Parts of Ropeway :-

Rope: A rope is made up of several strands of steel wires spun together. The rope or cable of a ropeway is used to fulfils two functions that are:-
It used to carry the suspended load and pull it along. Depending upon the design of a cable it can be used do one or both of these functions.

Ropeway carrier:  It consists of a carriage and a container . The carriage used for this  purpose is made up of a box head and a hanger. The box head  is attached  to the container with the hauling rope by means of a clip or wheels that run over the supporting rope in a bi-cable system and/or over the station. 

Drive station: Drive station consist of ropeways in the drive system, it includes a motor drive mechanism and a driving sheave. It contain some parts to maintain the tension of the rope.

Return station: Return station is at the end of the line  which contains a return sheave, from which the  carriers move back towards the drive station.

Sheaves: Sheaves are large diameter wheel which  found at  the both ends of the line and the stations. Their is hauling rope which passes around them. A driving sheave is run either by an engine or an electric motor connected to the sheave with a suitable drive mechanism.

Things You Should Know About PSA Oxygen Plant

PSA Oxygen Plant

PSA  Oxygen Plant in this  PSA stands for Pressure Swing Absorption Plant which is used to separate the oxygen from a mixture of gases . When pressure is applied to zeolite molecular sieves which attracts  oxygen more than nitrogen as its absorption capacity is different and oxygen exists the vessel.

What are the parts of PSA Oxygen Plant?

1) Air Compressor & After Cooler :- The Air Compressor reduces the  air up to 7.5 Bar and  then it allowed to  cool down  to ambient temperature in a shell or a  tube type heat exchanger. With the help of a mechanical unload the air compressor is been unloaded.

2) Oxygen Surge Vessel :- Oxygen from PSA Module have different varying purity depending upon the pressure it adsorbed during the one minute cycle time. The output received is also obtained at constant pressure with constant average gas purity.

3) Air Receiver :- It serves as a buffer vessel / small storage for compressed air to continuous feed the air to the system and as a result it kills the pulsation of pressure.

4) Raw Oxygen Flow Meter :- Raw oxygen flow meter (Rotameter) is used at the outlet of Oxygen Surge Vessel to check the quantity of Oxygen flow drawn in PSA system.

5) Percentage Oxygen Analyser :- It is a digital on-line oxygen analyzer is installed to monitor the oxygen Percentage level at outlet. 

Application

1) Metal industry

Oxygen is heavily used in the metal industry , because it improve the process efficiency by increasing the burning temperature which is used in the production of ferrous and non ferrous metals.

2) Chemical and petrochemical industries

In chemical and petrochemical industries, oxygen helps to increase the  oxidation of raw chemicals and  healing  of nitric acid, ethylene oxide  and other important chemical compounds.

3) Fish farming

The use of oxygen in the fish farming is to increase the survival and fertility ratios and reduce the incubation period.This oxygen  is applied for shrimps, crabs and mussels rearing.

4) Glass industry

  In glass furnaces industry oxygen is accomplished and it is  used to increase burning temperature  and burning processes improvement.

5) Waste management

Oxygen  is also used in incinerators which allows significantly increased the  flame temperatures and eventually ensures enhanced cost efficiency and incinerator production capacity.

Advantages :-  • It provides complete automation and simplicity in operation

•Quick start and stop facility.

• It has Moderate dimensions and light weight •Low noise level

• It helps to  Extended operational life

• It reduces Low operating costs

• To use it their is no special workshop is required

• It is easy to install and integration into an existing air system.

•Relativity low oxygen purity - 93-95% for adsorption
