Thermostatic Expansion Valve This type of thermostatic is used in industrial and commercial refrigeration system. This is an expansion device, and it is also known as constant superheat valve. In this ther are many different types of elements presented like evaporator, adjusting screw, feeler bulb, diaphragm, spring, valve, strainer. Let, Pb- pressure in …
Evaporative condenser Evaporative condenser is nothing but the evaporative cooling. That means the water evaporates, when the water comes in contact with the refrigerant flowing in the condensing coil. Evaporative condenser consist of a condenser coil, pump to circulate water from the sump, eliminators, fan, spray header and it’s nozzles, and a float valve. …
Regenerative Air Cooling System. Regenerative Air Cooling System is the another modified form of simple cooling system and it is additionally presented with a heat exchanger. Regenerative air cooling is used when the cooling turbine discharge temperature of a simple system is more. And this types are mostly is used in supersonic aircraft and rockets …
Refrigeration: Refrigeration is used to maintain and to reduce the temperature below that the surrounding temperature. It is done by the process of removing heat from an object under controlled conditions. It is used to store the products at required temperature. Ice can be manufactured easily through refrigeration. Advantages of Liquid Gas Refrigeration: .This refrigeration …

Electrical type temperature indicator: Electrical temperature indicator is used to identify the changes occur in the temperature of a required medium, In this type of indicator unit it consist of an engine which has an insulated wire connected to the panel to obtain an exact temperature indication. by making all the connections perfect it is …
USES OF ANTI-FREEZES: It is used at some places that falls below zero degrees temperature. Due to zero degrees when the water from the cooling system enters in to the engine jackets and at certain stage, at zero degrees it gets freeze by this the engine parts may gets damage like cylinder blocks, pipes and …
Fuel feed system in diesel engines: In this process the air is taken into the cylinder and compressed during the compression stroke and fuel is directly passed through the combustion chamber with high pressure at the end of compression stroke.the fuel inside the chamber burns due to the compressed air or self ignition. For this …
Starter Motor and it’s working: Construction of starter motor is same as of D.C generator construction. 1. Body 2. Armature. 3. Commutator. 4. Field winding. Working of starter Motor: The motor working depends on the type of current or that provided to a battery. It is fixed on the side of the engine. The motor …
Battery Ignition System: Starting of vehicle is easy by using battery type. It can produce efficient sparking even at low speeds also. In this energy is obtained by battery. It occupies a large space and wiring is complicated.
Contact breaking for Ignition system: It is used to make and break the current. To produce a high voltage in the secondary windings, contact break is used to break the primary current in primary winding of the ignition system. Cam,lever,heel,spring and bush are the main components.
