STAND FOR ADJUSTMENT AND TESTING OF THE EMERGENCY CLOSING CRANE AUTOMATOR (OPTIONS) Russian patent published in 2022 - IPC F15B19/00 G01M13/00 G01L27/00 

FIELD: testing equipment.

SUBSTANCE: inventions group relates to testing equipment for simulating the processes of changing the pressure of gaseous media. The stand for setting and testing the emergency shutdown valve consists of a drive made in the form of a gear motor (1) and a cylinder (2) with a piston (3) installed in it with the possibility of linear movement, an over-piston cavity (5) of the cylinder (2) connected to the buffer tank (6) and has a channel (7) for connection to the tested object. The piston cavity (9) is connected to the atmosphere. The piston is displaced by a screw-nut transmission connected to the piston (3), which converts the rotary motion of the drive into the reciprocating motion of the piston (3). Also, a variant of a stand for setting up and testing an emergency shutdown machine for a crane is disclosed.

EFFECT: increasing the accuracy of testing.
