JJHVT-S Hydraulic Vibration Tester
This instrument is a hydraulic vibration test unit of the comprehensive performance test platform for thin-walled stainless steel pipe fittings. It is mainly used to realize the hydraulic vibration test at the joints of the pipe fittings under the specified pressure after the thin-walled stainless steel pipes are connected to the pipe fittings, and to evaluate the connection performance of the pipe fittings.


GB/T 19228.1

JJHBDT-S Hydraulic Vibration Tester

This instrument is a hydraulic vibration test unit for the comprehensive performance test platform of thin-walled stainless steel pipes and fittings. The test pressure is provided by the hydraulic test control system. It is used to test the water pressure vibration resistance and evaluate the pipe fittings after the thin-walled stainless steel pipes are connected to the pipe fittings. Connection performance.

JJHTS-S Hydraulic test control system(host)

This instrument is the core of the hydraulic test control of the comprehensive performance test platform for thin-walled stainless steel pipes and fittings. It can be used for multiple hydraulic performance test units, multiple water pressure test units, multiple hydraulic vibration test units, and multiple bending angles at the same time. Test units, multiple hydraulic torsion test units, multiple maximum expansion and contraction test units, multiple deflection angle test units, and multiple vibration strain test units provide accurate test pressures.
