阻尼弹簧减震器的稳定性如何What is the stability of the damping spring shock absorber

    阻尼弹簧减震器若管道内的流体在流动过程中，由于管路的弯头，管径变化等因素，不可避免的有流速，压头和密度的变化。产生紊流，这种现象称作"管流脉动"，是管道及附属设备振动的主要原因。紊流既会引起随机的高频振动，也会激起结构或管系较低自振频率的振动;振动频率和幅值不规律变化，并伴有较大噪声。

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.

    动力设备动平衡性能差或阻尼器弹簧减振器基础设计不当会引起机械振动，为管道提供激励。在这种激振力作用下，管道及附属设备也会产生较大的振动响应。减震器公司给水泵出口管线发生振动并传递至连接管线，影响给水泵组的安全运行。

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.

    减震器主要用于减震后弹簧反弹时的振动和路面的冲击。虽然减震器弹簧在通过不平路面时可以过滤路面的振动，但弹簧本身也会有往复运动，减震器用来抑制弹簧的跳动。

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.

    阻尼弹簧减震器具有弹簧减振器的低频率和橡胶减振器的大阻尼等双重优点，将两者的优点结合，消除了弹簧减振器共振时振幅激增的现象，又解决了橡胶减振器固有频率较高的难题，是积极、消极隔振的理想产品。

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.

    阻尼弹簧减震器载荷范围广、适应性强，对积极隔振、消极隔振和冲击隔振能同时产生明显效果，是一种多功能通用性隔振产品，适用于-20℃-80℃的工作环境，其正常工作载荷范围内固有频率在1。5HZ-4.9HZ之间，阻尼比为0。065，是空调、恒温设备、风机、冷却塔、冷冻机组、压缩机，水泵等机载设备的理想减振产品。

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.

    阻尼弹簧减震器设备的运行频率经度值和弹簧减震器的固有频率应大于3。如何保证隔离效率在85%以上呢？当弹簧减震器偏转25毫米时，其固有频率为3-4赫兹。弹簧的水平刚度和垂直刚度应大于或等于1，额定负压后弹簧直径与弹簧高度之比应大于0.7。为了保证弹簧减震器在水平方向上的稳定性。

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.
