The regulation of productivity-power balance of compressor units at high pressures in the underground gas storages

The paper is dedicated to the control of the balance of power and productivity of compressor units in the underground gas storages at high pressures of absorption and injection. The studies and calculations based on the motor-compressors of AJAX brand have been carried out, and major technical suggestions prepared to solve the task. The increase of productivity in the high pressure diapason while absorption pressure rises, leads to the relevant increase of consumed power, and in the case of lack of drive power, a control necessity occurs. The parameters of the compressors depending on the increase of injection pressure have been conducted, and the corresponding graphs developed as well. To control the balance of productivity and power of piston-type compressors, the ways of deactivation of absorption valves have been analyzed and the productivity decrease estimated. It is shown that compared to the mechanical and pneumatic control, hydraulic regulation provides higher productivity.
