A barring device in a compressor is a mechanism or system designed to facilitate the manual rotation of the compressor shaft during startup or maintenance activities. Compressors are crucial components in various industries, and they often operate in conjunction with large motors. The barring device allows for the slow and controlled turning of the compressor shaft without the need for energizing the main motor.
Key features and purposes of a barring device in a compressor include:
Manual Rotation: The primary function of the barring device is to allow operators or maintenance personnel to manually rotate the compressor shaft. This can be necessary during startup procedures, inspections, or maintenance tasks.
Reduced Friction: The barring device is typically designed to minimize friction and resistance, enabling smooth and controlled rotation. This is essential to prevent damage to the compressor components and to ensure the safety of personnel.
Alignment Checks: During maintenance or inspection, it is often necessary to rotate the shaft to specific positions for alignment checks or to access different sections of the compressor. The barring device facilitates this process.
Emergency Situations: In the event of a motor failure or other issues preventing the normal operation of the compressor, the barring device can be crucial for emergency procedures. It allows for controlled manual rotation to address the situation.
Shaft Positioning: The device helps position the compressor shaft precisely, allowing for the correct alignment of various components, such as blades, seals, and bearings.
Safety Features: Barring devices often incorporate safety features, such as interlocks, to ensure that the compressor is not accidentally started while the barring device is engaged. This helps prevent accidents and damage to the equipment.
It's important to note that the design and implementation of barring devices can vary depending on the type and size of the compressor, as well as the specific requirements of the application. Barring devices are commonly found in large compressors used in industries such as petrochemical, refining, power generation, and other heavy industrial settings.

In a hermetic compressor, the internal overload protector is typically located on the compressor's start winding terminal. This overload device is designed to interrupt the electrical current if the compressor overheats, helping to prevent damage from excessive temperature. It ensures the compressor operates safely and efficiently.

The high pressure side is the discharge side. It runs from the compressor outlet to the metering device inlet. The low pressure side is the vacuum side. It runs from the metering device outlet to the compressor inlet.

There are two parts which do. The first is the compressor - the high side starts at the compressor outlet. The other is the metering device (either a Thermal Expansion Valve or a Fixed Orifice Tube). The high pressure high ends at the metering device inlet. The low pressure side starts at the metering device outlet and ends at the compressor inlet.
