A degassing device for a fluid mechanical testing system

Abstract

The invention discloses a degassing device for a fluid mechanical test system, which mainly includes an outer frame, a spiral piece, a middle pipe, an exhaust module, a degassing shell, a rotating shaft, a shaft locking seat and a driving module, and the inner middle part of the outer frame runs through the The middle pipe is fixedly installed, and the outer side of the middle pipe is fixedly installed with spiral pieces. The upper and lower ends of the middle pipe are equipped with drainage heads, and the left ends of the two drainage heads are equipped with a confluence pipe through a tee joint. The upper and lower ends of the middle pipe are two A shaft lock seat is fixedly installed on the inner wall near the drainage head. The present invention has reasonable structure design, flexible and stable structure, high degree of automation, self-adaptation according to the real-time situation, and the gas discharge is relatively thorough under the least amount of water output. Excessive adjustment during the adjustment process causes water to overflow from the exhaust pipe, reducing the number of precision drives, reducing the failure rate, and reducing manufacturing and post-maintenance costs.

Description

Technical field [0001] The present invention relates to a fluid testing system, specifically a fluid mechanical testing system with an outgassing device. Background [0002] In the process of transporting liquids in pipelines, there is a large amount of gas. Pipeline gas storage increases the operating resistance, increases energy consumption, and can directly or indirectly lead to pipe bursting in severe cases. At the same time, pipeline gas storage can cause pressure instability, long-term pressure shock caused by pipeline interface and pipe fatigue, greatly reducing the service life of pipelines. In summary, pipeline gas storage will not only bring certain economic losses, but also have safety risks. Fluid mechanical test system pipeline storage, will induce cavitation, the formation of strong vibration and noise, accelerate the mechanical wear of pipelines and valves, while vibration caused by loose fasteners, and cause certain damage to the reliability of pipelines and syste...

AI Technical Summary

Problems solved by technology

Gas storage in pipelines increases running resistance and energy consumption, and in severe cases can directly or indirectly lead to pipe bursts

At the same time, gas storage in pipelines can cause pressure instability, and long-term pressure fluctuations cause fatigue of pipeline joints and pipe materials, greatly reducing the service life of pipelines

In summary, gas storage in pipelines will not only bring about certain economic losses, but also pose potential safety hazards.

Air in the pipeline of the fluid mechanical testing system will induce cavitation, form strong vibration and noise, accelerate the mechanical wear of pipelines and valves, and at the same time cause loosening of fasteners due to vibration, and cause certain damage to the reliability of pipelines and systems, seriously Affect the test effect and the operating environment, causing distortion of the pipeline hydraulic test, increasing the head of the frictional resistance, increasing the pump head, reducing the water output, resulting in difficulty in water discharge, and even the terminal does not come out of water, and more serious may cause tearing of weak points , a direct threat to production safety

[0003] The existing degassing structure is simple, unable to adapt to the situation of different air content in the water for real-time adjustment, resulting in incomplete degassing when the air content in the water is high, and too much water flowing out of the pipeline when the air content is low, which affects the transmission efficiency, and The degassing automation of the device is low, resulting in poor practicability of the equipment, which cannot be self-adapted according to the real-time situation, the device has too many driving devices, its own volume is large, and the manufacturing cost is high
