Expansion of Conditions

Operating costs and conditions depend on working conditions. Change of loading configurations may cause malfunctioning of compressor pistons, valves and shafts. The loading quantities varies due to the wide range of carrying conditions especially in piston compressors. The productivity problem occurs more at unspecified high pressures and low labours. Such changes require the following control system and conditions to be stable:

• Compressor torque effort
• Shaft voltages
• Resonances

Therefore, it is important to design systems for the range of conditions, not for a specific usage condition. When the cooling system or similar systems in the compressor environment are considered to be necessary, it may be necessary to develop them as "cooling room" systems by making an addition. It is important that the compressor's ancillary systems, such as the electric motor, are included in this expansion.

 Completion of Design Guidelines in a Correct Way

Design and the following analysis measurements are important for efficient operation conditions. For this, it is necessary to fully comply with the guidelines given. Reactions and tensions, controls such as compliance with compressor operating conditions should be completed with final analyses and load steps. For this, the following stages are important:

• Analysis of endpoints: Analysis of high-power double-acting and single-acting chassis, maximum and minimum suction and discharge pressures, closed and open valves and other parts is required.
• Analysis of torsional close speeds: Determination of the natural torsional frequency of system components should be analyzed by including ∓10% frequencies.
• Analysis of unusual conditions: When the compressor is running on the bypass, it can significantly change the torsional response of the system. This means that it causes a different mode of operation for mechanical malfunctions. Therefore, the analysis of potential errors is important.
• Proper placement of cylinders: It is important where cylinders with the highest torque effort are placed in the shaft speed sequences close to the torsion system. In terms of controlling the torsional response, the cylinders should be placed in certain positions instead of bringing them together.

 Operation and Installation Conditions

Another component that affects compressors is the difference of conditions. It is important to minimize the difference of conditions which greatly affect both the effort curve and frequency. Gas and inertial forces, compressor torque effort, are geometrically mutual force functions. These functions are vector systems that balance each other. In addition, it is important to fulfill some physiological conditions in order to maximize working conditions. Any change in gas composition causes differences in density and specific heat. These changes in operating conditions will affect the compressor effort. For the operation of the compressor and the maximization of operating conditions, the following conditions should be considered:

• Constancy of discharge pressure
• Variability of suction pressure
• Constancy of gaps in volume
• Constancy of speed
• Stabilization of gas properties

The operating conditions of compressors are important for changing the properties of torque effort. As it is seen, the operating conditions and other conditions develop in an interconnected way.
