“…There is a growing trend worldwide towards research and development of components and hydraulic systems supplied with water [6,13,14,28,32,33,37]. Therefore, a hydraulic motor dedicated to oil systems should not be used in systems where the working medium is water [27].…”

“…Water hydraulics could be used especially in small vessels (yachts and small cruise ships) in regions of the world where there is no frost. To this end, it is necessary to develop and test innovative components for hydraulic water systems [25,26,28,29,37]. Thus, it was reasonable to develop a new hydraulic motor dedicated to supply with water.…”

In this paper, mechanical losses in a hydraulic motor supplied with water and mineral oil (two liquids having significantly different viscosity and lubricating properties) are described and compared. The experimental tests were conducted using a special design (prototype) of a hydraulic satellite motor. The design of the satellite motor is presented. This motor was developed to supply both with water and mineral oil and features a non-circular tooth working mechanism. The paper also characterizes sources of mechanical losses in this motor. On this basis, a mathematical model of these losses has been developed and presented. The results of calculation of mechanical losses according to the model are compared with the experimental results. Experimental studies have shown that the mechanical losses in the motor supplied with water are 2.8 times greater than those in the motor supplied with oil. The work demonstrates that the mechanical losses in both the motor supplied with water and the one supplied with oil are described well by the mathematical model. It has been found that for the loaded motor working at high speed, the simulation results differ from experimental ones by no more than 3% for oil and 4% for water.

Wind is a renewable energy and has many benefit. This energy is used by the salt farmers in the north coast of Java. Windpump is used to convert the wind energy for pumping water from sea to the salt pond. The purpose of this study is to get the performance of salt farmer’s windpump from Demak Region, Central Java for water lifting with vertically reciprocating pump. Rotation of shaft is directly converted to linear translation by crankshaft and connected to the piston pump. This study uses three variations lenght of the crankshaft arm in a piston pump. In 2 up to 5 m/s of wind speed range, the windmills from Demak with arm length of 5.0 cm, 7.5 cm, and 10.0 cm has an average volume flow rate of 0.89 litre/s, 1.8 litre/s, and 1.3 litre/s, respectively. For a day, these variations has a daily average volume of 19,278 litre, 39,162 litre, dan 27,804 litre.
