AI Technical Summary

Technical Problem

Existing water damping systems are prone to damage due to excessive water pressure on components during high-speed testing, and failure of water to enter the space between the storage tank and the damping tank in time can lead to cylinder explosion.

Method used

Design a water damping cylinder, including a cylinder body, a throttling tube, a moving piston, and a rope. The throttling tube is equipped with multiple through holes and a buffer section. The liquid moves alternately on both sides of the piston to avoid excessive water pressure. The damping and buffering stroke are adjusted by the density of the through holes.

Benefits of technology

It effectively avoids damage to components caused by excessive water pressure, improves testing accuracy and safety, and has a simple structure and small footprint.

Abstract

The utility model discloses a water damping cylinder and water damping system for accelerating test, including cylinder, the throttle pipe in cylinder, the reciprocating piston that moves in the throttle pipe and the power rope and reset rope that connect reciprocating piston both ends, the power rope passes through the cylinder and extends outward, the both ends of cylinder are sealed, is equipped with the water inlet and the drain in the cylinder, the both ends of throttle pipe are connected with the cylinder end, and the throttle pipe includes the throttle short pipe of successive interconnection, and the lateral wall distribution of part or all throttle short pipe has a plurality of through -hole. The utility model discloses the mode of through -hole is set to the lateral wall of throttle pipe and realizes liquid alternately in reciprocating piston both sides activity, and liquid can pass through the backflow of through -hole, need not move to the throttle pipe end, avoid the water pressure in the cylinder too big, and can change the damping and the buffer stroke through the mode of replacing throttle short pipe, and the area is small, and it is more convenient and fast to use.
