Comparison of the powers of energy losses in a variable capacity displacement pump determined without or with taking into account the power of hydraulic oil compression
Abstract
Powers of energy losses in a variable capacity displacement pump are compared with or without taking into account the power of hydraulic oil compression. Evaluation of power of liquid compression in the pump was made possible by the use of method, proposed by the Author, of determining the degree of liquid aeration in the pump. In the method of determining the liquid aeration in the pump and of powers of volumetric losses of liquid compression a simplified formula was used describing the field of indicated work of volumetric losses of liquid compression during one shaft revolution at indicated increase of pressure in the chambers. Three methods were used for comparing the sum of powers of volumetric losses due to leakage and of compression and also of mechanical losses resulting from increase of indicated pressure in the working chambers.
