阻尼彈簧減震器的穩定性如何What is the stability of the damping spring shock absorber

    阻尼彈簧減震器若管道內的流體在流動過程中，由於管路的彎頭，管徑變化等因素，不可避免的有流速，壓頭和密度的變化。產生紊流，這種現象稱作"管流脈動"，是管道及附屬設備振動的主要原因。紊流既會引起隨機的高頻振動，也會激起結構或管系較低自振頻率的振動;振動頻率和幅值不規律變化，並伴有較大噪聲。

If the fluid in the pipeline is flowing in the process of damping spring shock absorber, due to the elbow of the pipeline, the change of pipe diameter and other factors, theRE will inevitably be changes in velocity, pressure head and density. Turbulent flow, which is called "pipe flow pulsation", is the main reason for the vibration of pipelines and auxiliary equipment. Turbulent flow can not only cause random high frequency vibration, but also cause lower natural frequency vibration of structure or pipe system; vibration frequency and amplitude change irregularly, accompanied with large noise.

    動力設備動平衡性能差或阻尼器彈簧減振器基礎設計不當會引起機械振動，為管道提供激勵。在這種激振力作用下，管道及附屬設備也會產生較大的振動響應。減震器公司給水泵出口管線發生振動並傳遞至連接管線，影響給水泵組的安全運行。

Poor dynamic balance performance of power equipment or improper design of damper spring damper foundation will cause mechanical vibration and provide excitation for pipeline. Under the action of this exciting force, the pipeline and its accessory equipment will also produce larger vibration response. The vibration of the outlet pipeline of the feed water pump of the shock absorber company is transmitted to the connecting pipeline, which affects the safe operation of the feed water pump group.

    減震器主要用於減震後彈簧反彈時的振動和路面的衝擊。雖然減震器彈簧在通過不平路面時可以過濾路面的振動，但彈簧本身也會有往複運動，減震器用來抑製彈簧的跳動。

The shock absorber is mainly used to reduce the vibration of spring rebound and the impact of road surfACE. Although the shock absorber spring can filter the vibration of the road when it passes through the uneven road surface, the spring itself will also have recIPRocating motion, and the shock absorber is used to suppress the spring's jumping.

    阻尼彈簧減震器具有彈簧減振器的低頻率和橡膠減振器的大阻尼等雙重優點，將兩者的優點結合，消除了彈簧減振器共振時振幅激增的現象，又解決了橡膠減振器固有頻率較高的難題，是積極、消極隔振的理想產品。

The damping spring shock absorber has the dual advantages of low frequency of spring damper and large damping of rubber shock absorber. Combining the advantages of the two, the phenomenon of amplitude surge during resonance of spring damper is eliminated, and the problem of high natural frequency of rubber shock absorber is solved. It is an ideal product for positive and negative vibration isolation.

    阻尼彈簧減震器載荷範圍廣、適應性強，對積極隔振、消極隔振和衝擊隔振能同時產生明顯效果，是一種多功能通用性隔振產品，適用於-20℃-80℃的工作環境，其正常工作載荷範圍內固有頻率在1。5HZ-4.9HZ之間，阻尼比為0。065，是空調、恒溫設備、風機、冷卻塔、冷凍機組、壓縮機，水泵等機載設備的理想減振產品。

The damping spring shock absorber has a wide load range and strong adaptability. It can produce obvious effects on active vibration isolation, negative vibration isolation and impact vibration isolation at the same time. It is a multi-functional universal vibration isolation product, which is suitable for the working environment of - 20 ℃ - 80 ℃, and its natural frequency is 1. The damping ratio is 0 between 5Hz and 4.9hz. 065 is an ideal damping product for air conditioning, constant temperature equipment, fan, cooling tower, refrigeration unit, compressor, water pump and other airborne equipment.

    阻尼彈簧減震器設備的運行頻率經度值和彈簧減震器的固有頻率應大於3。如何保證隔離效率在85%以上呢？當彈簧減震器偏轉25毫米時，其固有頻率為3-4赫茲。彈簧的水平剛度和垂直剛度應大於或等於1，額定負壓後彈簧直徑與彈簧高度之比應大於0.7。為了保證彈簧減震器在水平方向上的穩定性。

The longitudinal value of running frequency and natural frequency of spring shock absorber should be greater than 3. How to ensure isolation efficiency above 85%? When the spring damper deflects 25 mm, its natural frequency is 3-4 Hz. The horizontal and vertical stiffness of the spring should be greater than or equal to 1, and the ratio of spring diameter to spring height should be greater than 0.7 after rated negative pressure. In order to ensure the stability of spring shock absorber in horizontal direction.
