Abstrakt
| The article deals with possibilities of using and application of cheaper alternatives of devices for transportation and evacuation of air mass and gases in real operation in energetics and in other associated industries. This article deals with the measurement of the important parameters of a water ring vacuum pump. Then the parameters that are declared by the Chinese producer are compared with real and actually measured values obtained by the laboratory testing. Operational tests were performed after validation measurements and there were created operational characteristics of the vacuum pump. The result of the measurement is the evaluation and comparison of the advantage of installing a vacuum pump from a cheap Chinese manufacturer compared to established suppliers who offer guaranteed quality, but at a higher purchase price. Measured values and tests proves clearly that the values from a device label, guaranteed by the manufacturer, cannot be trusted, and when purchasing these devices from foreign or even unknown manufacturers, it should be taken into account that there may be other risks - such as the quality of the materials used, reliability, etc. The customer should consider if they wants to save money at the expense of quality and reliability.. |
