| At Las
Vegas Air Conditioning Repair our technicians and owner
are highly qualified to work with semi-hermitic
compressors. Semi- hermetic compressors has no shaft
openings. The driving motor is completely enclosed in
one section of the assembly. The compressor is in the
other section. The motor shaft is an extension of the
compressor shaft. The two sections are gasketed and
bolted together.
Semi-hermetic compressors do not
have the disadvantage of open type compressors that is,
there is no exposed shaft prone to leak refrigerant and
oil out of the system and air and water into the system.
However, semi-hermetic compressors do not have the
service and power source advantages of open compressors,
either. The compressor speed is fixed by the speed of
the motor. Servicing the compressor or motor takes both
off line.
Semi-hermetic compressors have
an advantage over welded or sealed hermetic compressors.
Since they are bolted together, they can be disassembled
and serviced in the field. The semi-hermitic compressor
has proportionally higher cost than an open type
compressor or sealed hermetic compressor of equal
capacity. |
