High Pressure Control
If all the gas generated cannot be drawn in by the compressor and passed on to the filling manifold, either due to low capacity of the compressor or fast generations, gas pressure will gradually build in the generator. When the gas pressure reaches a predetermined level (about 0.5 kg /cm2) carbide charging will be cut off automatically and further generation of gas is stopped.
There is no expensive gasholder with the SANGHI Acetylene Generator. This item alone will reduce the investment on such a plant. Further, as the gas generated is always at a positive pressure, the pumping cost is also reduced. Since the generator is constantly at a positive pressure, (once the plant has been purged with Nitrogen) no air enter the system,
and it is this feature which makes “SANGHI” Plant inherently very safe.
Expansion Engine is a vertical reciprocating machine which can expand air adiabatically from operating air pressure to 5 Kgm / cm2 to produce the required cold for the Oxygen / Nitrogen plant. It greatly helps to reduce power consumption.
This consists of two layers of regenerative chemicals,which remove additional impurities. The purifying agent may be reactivated for re-use by the atmosphere air. For continuous operation one extra charge of chemicals can be kept in open wooden trolley.
Oxygen / Nitrogen Liquid Pump
The liquid pump is a horizontal reciprocating pump. It can pump cryogenic liquids such as Liquid Oxygen, Nitrogen and Argon upto 165 Kgm/Cm2 pressure normally and 250 Kgm / Cm2 pressure in special cases. The pumps are simple and requires least maintenance.
The equipment is installed between the chemical purifier and the high-pressure compressor which helps to remove additional impurities from the gas if any.
Air Seperation Unit / Cold Box
Air Seperation Unit / Cold Box consists of Distillation Column with Heat Exchangers for heat transfer between the incoming air and the out going cold Nitrogen and Oxygen. It is equipped with Expansion valves for controlling the operation of the plant. Control panel for the cold box is provided with the plant. Defrost heater for thawing plant is also provided on the cold box. It is also equipped with liquid oxygen pump which is a single cylinder equipment and delivers Bone-dry Oxygen upto pressure 165 Kg/Cm2. Cold box is insulated withperlite for minimizing cold losses and reducing power consumption.
For filling of the cylinders an I.R. make reciprocating, oil lubricated, multi-stage, water submerged compressor with intercoolers,safety relief valve for each stage, driven by a 15 H.P. Flame Proof Motor confirming to
Sanghi Water Softner Plant
Custom built water softner plants with flow Capacities ranging from 0.7m3 / Hr to 12m3 / hr with an output per regneration ranging from 8.1m3 to 20.3m3 max. working pressure 3.0 kg / cm2.
No Loss -Carbide charge
No gas is lost or wasted while charging the carbide because that section is completely sealed off from the generator by a high pressure hydraulically operated valve.All the above controls are automatic and require no attention from the operator. There is a further safety device, in terms of an alarm bell, which will ring continuously till the fault is corrected.
Sanghi Valves for cylinders
Oxygen / Nitrogen / Acetylene / Argon Cylinder valves with SS304 spindle & Teflon. This cylinder valve is fixed to a gas cylinder by screwing & its essential functions are as under :
– To enable filling of gas into the cylinder.
– To ensure proper storage of the gas – inside the gas cylinder.
– To release the gas as and when – required.
– To act as a safety device for the cylinder if valves are provided with safety.
