Abstract

The invention provides a damper and an overspeed testing machine with the damper. The damper comprises a shell, a damping spacer bush, a damping seat and a detecting device. A core rod penetrates in the shell. The damping spacer bush is arranged in the shell so that vibration of the core rod can be reduced. The damping seat is arranged in the shell and is connected with the damping spacer bush. The detecting device is arranged on the shell and detects vibration of the core rod by detecting vibration of the damping seat. By means of the damper, the problem that in the prior art, a damper cannotensure safety of the overspeed testing machine is solved.

Description

technical field [0001] The invention relates to the field of mechanical vibration reduction, in particular to a damper and an overspeed testing machine with the same. Background technique [0002] At present, most of the existing traditional impeller overspeed testing machines are directly driven by motors or belt drives, and the speed is generally only between 10000r / min and 25000r / min. 40000r / min. At this time, the test has strict requirements on the vibration of the equipment during operation. If the vibration is too high, it needs to be forced to stop, otherwise it will easily cause damage to the equipment and even lead to safety accidents. [0003] In the existing equipment, devices such as dampers are generally used to slow down and absorb the vibration of the equipment, but the vibration absorption effect of the damper in the existing equipment is not good, and it affects the rotation speed and power consumption of the test piece, so it can only be adapted to lower sp...
