non-return or automatic valve and then to the cylinder air start valve. Opening of the cylinder air start valve will admit compressed air into the cylinder. The opening of the cylinder valve and the remote operating valve is controlled by a pilot air system. The pilot air is drawn from the large pipe and passes to a pilot air control valve which is operated by the engine air start lever. When the air start lever is operated‚ a supply of pilot air enables the remote valve to open. Pilot air for the

[pic] TAKEING THE MYSTERY OUT OF THE TXV The thermostatic expansion valve has been considered by some to be a mysterious and complex device. As a result‚ many valves are needlessly replaced when the cause of the system malfunction is not immediately recognized. Actually the thermostatic expansion valve performs only one very simple function. –it keeps the evaporator supplied with enough refrigerants to satisfy all load conditions. It is not a temperature control‚ suction pressure control

Adjust the pressure regulator on the air supply (As) to 2 atm. 2.) Familiarization with 5/3 lever-operated valve‚ closed center. 3.) Closed center is obtained when the valve is not activated. 4.) Pushing the lever to one side will activate one state of air flow through the valve. Pushing the lever to the other side will activate the other state of the valve. 5

A fermenter is an apparatus that maintains optimal conditions for the growth of microorganisms. The main function of the fermenter is to provide a controlled environment for the growth of a pure culture or of a defined mixture of microorganisms or animal cell to obtain the desired product. Different parts of fermenter:- 1) Fermenter Vessel: A suitable vessel is used to carry out the whole fermentation process. The vessel is capable of being operated aseptically and meet the containment

CHAPTER 1 INTRODUCTION At first glance the idea of running an engine on air seems to be too good to be true. Actually‚ if we can make use of air as an aid for running an engine it is a fantastic idea. As we all know‚ air is all around us‚ it never runs out‚ it is non-polluting and it is free. An Air Driven Engine makes use of Compressed Air Technology for its operation. Compressed Air Technology is now widely preferred for research by different industries for developing different drives for different
