Nowadays, relations between states are developing in the context of globalization. The international community is exposed to various challenges and risks. The goal of the institutions of global economic governance in these conditions is ensuring the stability of the world economy and stimulating its growth.To develop an effective strategy, it is necessary to increase the speed and efficiency of responding to economic challenges and crisis situations. The relevance of the study is determined by the complexity, contradictions and dynamism of the system of international economic and political relations. The purpose of the research is to evaluate the work of international institutions of global governance by the example of the IMF and WTO. For this, we consider their new models for regulating the world economy. In conclusion, the urgent need to reform global governance institutions is noted. Two main problems of ineffective functioning of global governance institutions are identified. Every strong state should be interested in achieving solid results. Each member state of world organizations should aim at establishing interstate interaction and mutual understanding. The world needs transformation in the interests of security and the soundness of politics and economics. We believe that a new complex, developed system of international relations is the basis of all regulatory world processes of the present and future.

“…Defects occurring in working parts or driving elements of some machines often lead to higher energy consumption, which can be also used as a sign of failure [12]. It is known to use nondestructive testing methods (such as, for example, ultrasound scanning, magnetic method, gamma-radiography or capillary examination [11]) in order to detect damage to individual pump components.…”

The article discusses the vibrodiagnostic tests of a multi-stage high-power rotodynamic pump. The tested pump was operated as a feed water pump in an industrial combined heat and power plant. However, some time ago, its dynamic performance started to deteriorate. Therefore, diagnostic tests were carried out, the aim of which was to identify the reasons for the increased vibration level and to minimise it. The scope of the performed work included both the analysis of possible excitation forces originating from the flow system and measurements of the pump vibrations at different power levels. Additionally, at selected measuring points, vibration velocity spectra were registered and eigenfrequencies were determined. The analysis of the obtained results allowed to clearly identify the causes of dynamic problems and introduce changes that enable their elimination.
