High-pressure water jet impact feedback protection device

Abstract

The invention relates to the field of water cutting and industrial cleaning, and particularly relates to a high-pressure water jet impact feedback protection device. One end of a cross bar is fixedlyarranged on a suspension, a rack is arranged at the section of the cross bar close to the suspension, a gear is arranged below the rack and meshed with the rack; a nozzle is arranged on the left end of a high-pressure spraying pipe, a boss sleeve is fixedly arranged on the high-pressure spraying pipe, a spring is arranged on the boss sleeve, the right end of the high-pressure spraying pipe penetrates through the suspension and is fixedly arranged together with a chuck; a displacement sensor is arranged on the suspension, a pull bar and the chuck are connected, a roller is arranged on the lowerend of the suspension so as to ensure that the suspension stably moves along the linear direction. The high-pressure water jet impact feedback protection device has the advantages of being capable ofrealizing the automatic feeding of the high-pressure spraying pipe, detecting the counter-force change of water jet in real time, and automatically adjusting the jetting distance. Springs with different elastic coefficients can be changed, and the applicability of the device can be promoted. The variation of the springs can be detected by adopting the displacement sensor, the installation is convenient, and the mechanical structure is protected from being destructed by the counter force of the high-pressure water jet. The device is applicable to water cutting and industrial cleaning.

Description

technical field [0001] The invention relates to the field of water cutting and industrial cleaning, in particular to a high-pressure water jet impact force feedback protection device. Background technique [0002] High-pressure water jet technology is an emerging technology that has developed very rapidly in recent years. The high-pressure water generated by the high-pressure generating device is gathered into a water jet through the nozzle and hits the surface of the object to complete surface cleaning, cutting, crushing and other operations. This cleaning or cutting method is fast, efficient, pollution-free and low in cost, and is a reliable, economical and practical cleaning or cutting technology. [0003] The important technical index of high-pressure water jet flushing and cutting technology is the impact force, which determines the effect of high-pressure water flow on the surface of the object. Due to the influence of the fluid characteristics, when the high-pressure ...

Problems solved by technology

[0003] The important technical index of high-pressure water jet flushing and cutting technology is the impact force, which determines the effect of high-pressure water flow on the surface of the object. Due to the influence of fluid characteristics, when the high-pressure water impacts the surface of the object, the impact force is affected by the structure of the nozzle and the spray distance. Influenced by other process factors, it often does not remain constant, and the actual water jet impact force has a certain deviation from the theoretical calculation value, which will greatly affect the actual effect of water jet flushing or cutting

At the same time, excessive impact reaction force will cause damage to the mechanical structure of the water jet device, and even cause safety accidents
