Know All About Semi-Hermetic Compressors

With technology upgrading and paving its way to the field of engineering, people have continued to believe in the most straightforward products. This is where we introduce you to the semi-hermetic compressors that offer immense advantages for refrigerating and air cooling systems. 

These were first manufactured in the late 1940s, and since then have been used for refrigeration. With an extraordinary improvement in the Semi-Hermetic compressor’s working, these provide access to being repaired rather than replaced when a part of the system fails. 

A semi-hermetic compressor uses a large cast-iron casing secured with screws which can be opened to repair or replace motor and compressor components. The motor and the compressor are fixed together and can be accessed anytime when required. So, when it comes to ‘repair and maintenance of Semi-Hermetic compressor’

the semi-hermetic compressor has no route for the gas leakage!

What is a semi-hermetic compressor?

The word hermetic is derived from the word hermit, which means to be isolated from the outside world. This means that the ammonia compressor parts are isolated or sealed in a closed system in a compressor.

There are 3 distinct types – Open, Hermetic, and Semi-Hermetic. The semi-hermetic has the compressor body and the engine sealed inside the case during operation, but it can be opened for inspection and maintenance when required.

The functioning of the semi-hermetic compressor 

The semi-hermetic compressor works in the following way –

  • The compressor raises gas pressure and transports the gas through the piping system for distribution. 
  • The electricity when pushed in, the compressor crankshaft rotates. 
  • During the downstroke, the compressor pump contains a piston which creates a low-pressure between the piston top and the compressor cylinder. 
  • And, during the piston upstroke, the suction valves close and further increases the pressure, leading to the gas being compressed. 

The entire cycle completes when the semi-hermetic compressor piston reaches the top of the cylinder and the discharge valves close. Again the suction valve opens and the downstroke starts, drawing the gas in, hence the cycle completes. 

The applications of semi-hermetic compressors 

These amazing compressors are used in appliances like refrigeration compressor parts and air conditioning units. These are the preferred choice for larger-scale units and are trusted by many industrialists. Being an efficient option, the big refrigeration units use it.

These are used in industrial cold rooms, bar cooling, air conditioning systems, etc., wherever the temperature control is required.
