摘要

FIELD: machine building.;SUBSTANCE: invention is related to power machine building and may be used, in particular, in hydraulic tests of heat exchange unit elements and heat exchange units of modular-sectional regenerative air heater. Technological complex of equipment for hydraulic tests comprises the following components that are technologically connected by working fluid: test bench for hydraulic tests of bent heat exchanging pipes, test bench for hydraulic tests of units with headers of air supply and exhaust and bundle of heat exchange pipes and test bench for drying of units with headers of air supply and exhaust, common or separate hydraulic systems with forcing installation with double-step supply of working fluid for stage of pipes filling and for stage of test pressure pulling. To connect bent pipes subject to hydraulic tests, clamping devices are used, developed in invention as hydraulic clamping devices with drives from pressure of hydraulic system working fluid pressure. Hydraulic system comprises tank with working fluid, forcing installation, piping from pipelines, stop valves and measuring instruments, and also foresaid hydraulic clamping devices. Method of hydraulic system assembly includes assembly of equipment, including installations with foresaid hydraulic clamping devices, which provide compression force from working fluid pressure. Methods of bent pipe hydraulic tests in version realisation provide filling of pipes packet with working fluid and their pressurising with application of foresaid hydraulic clamping devices with different realisation of their fixing on support structure. Hydraulic system for tests comprises support structures developed in invention for installation of units with air supply and exhaust. Test bench for drying of heat exchange units in version realisation comprises berth for unit installation, system of plugs and support system developed in invention.;EFFECT: increase of efficiency and reduction of power intensity, labour and material expenses for performance of hydraulic tests.;34 cl, 24 dwg
