Hydraulic pumps are the part of hydraulic machines family and are commonly used in almost all branches of the industrial engineering. They have various possibilities of usage and therefore there is a huge amount of these machines all over the world. Lots of companies are focused on increasing output power as well as efficiency. One of the solutions how to reach higher efficiency is operating control and regulation of hydraulic pumps. The intentions of this work were to compare two different hydraulic pumps from the Wilo Company based on measuring of operating parameters. Two types of pumps " Stratos and Top-S " were chosen. The Stratos pump is electronically regulated, with possibility of settings of different operation modes. The Top-S pump is the common type without outer regulation. The operating parameters of the Stratos pump were measured during the different modes of the constant revolution, constant and variable differential pressure. The whole mechanism was vibrating during reducing of the flow's rate in the differential mode. These vibrations were measured as exact as measure equipment allowed. While measuring the power input and efficiency there were taken fifteen different measurements on the Stratos pump. The operating characteristics of the Top-S pump along with power input and efficiency were measured in three operating modes, which are available. Measured results were pictured into graphs and compared to each other. The Stratos pump shows higher efficiency. This pump is electronically controlled and it uses modern technologies. On the other hand it is more expensive than the Top-S pump. |
