Reciprocating Hermetic Compressor Manufacturer,Supplier and Exporter in India
Product Code : EL-TWL-13127
Jlab Export is a leading Reciprocating Hermetic Compressor Manufacturer,and suppliers in India
This sectioned reciprocating hermetic compressor shows the piston type of compressor sealed inside many domestic refrigerators and freezers. Cut from an original compressor, it lets students see the piston, cylinder, valves, crankshaft and motor inside the welded shell. The parts are colour coded, and the belt drive with its rotating handle moves the piston through each stroke.

Practicals for RAC Trainees
Trainees first turn the handle and call out each stage as the piston moves: suction, compression, discharge. They trace the gas from the suction line into the shell, through the cylinder and out to the discharge line. Then they find the motor windings and the terminal block where the supply enters the shell.
The next step is a sealed Compressor on the bench. Using a Digital Multimeter, students read the resistance between each pair of the three terminal pins. The highest reading is start to run, and the pin common to the two lower readings is the common terminal. The cut-away shows them the windings they have just measured.
Frequently Asked Questions
How does a reciprocating hermetic compressor work?
The motor turns a crankshaft, and a connecting rod drives the piston up and down in its cylinder. On the down stroke a suction reed valve lets gas in. On the up stroke the gas is squeezed until the discharge reed valve opens and sends it on to the condenser.
Where is this type of compressor used?
Small hermetic piston compressors are common in domestic refrigerators, freezers and water coolers. They suit the small cooling loads of these appliances and need no service in their working life, as long as the system stays sealed and clean.
What usually damages a hermetic piston compressor?
Liquid refrigerant reaching the cylinder can break the reed valves, because a piston cannot squeeze a liquid. Overheating, a low charge or moisture in the system can burn the motor windings. The cut-away shows students where both faults happen.
Why do small hermetic compressors need a start relay and an overload?
The motor has a run winding and a start winding. The relay switches the start winding in for the first moment and drops it out once the motor is up to speed. The overload cuts the supply if the motor draws too much current or runs too hot.
