What is a spring damper used for?
Recently, many people on the Internet asked Jinnuo shock absorber manufacturer, what is the purpose of spring shock absorber? For what industry? Today, Songxia shock absorber manufacturer will answer these questions one by one.
The spring damper is a vibration control installation with flexible response to displacement; Spring damper is mainly used for anti vibration of pipelines and equipment in nuclear power plants, thermal power plants, chemical plants, steel plants, etc. It is often used to control the vibration of pipeline system caused by fluid vibration excitation (such as fluid pulsation, two-phase flow, high-speed flow and aeolian vibration).
The spring damper can effectively control the vibration and swing of various frequencies, but it limits the normal thermal displacement of the pipeline at a certain level. The additional force generated by the spring damper on the pipeline shall be fully considered in the design.
In order to reduce the vibration and impact of the road surface mentioned above, the spring is required to absorb the energy of vibration and impact. The spring is an energy storage element in the suspension, but it is not enough to store it for the time being. It is also necessary to consume the energy that is harmful to the comfort and dominant stability of the vehicle. It is the shock absorber's turn to exit, The working principle of the hydraulic shock absorber is that when the frame and the axle reciprocate in relative motion, and the piston reciprocates in the cylinder barrel, the oil in the shock absorber housing will repeatedly flow from one inner cavity to another through some narrow pores. At this time, the friction between the hole wall and the oil and the friction within the liquid molecules will constitute the damping force for vibration, The vibration energy of the body and frame is converted into heat energy, which is absorbed by the oil and shock absorber housing and then dispersed to the atmosphere. To put it simply, it converts kinetic energy into heat energy. If the shock absorber runs continuously on the test bench for several minutes, the outer wall of the shock absorber oil storage cylinder will become very hot, even hot.

Introduction of non-metallic contraction joint and precautions for its device
The non-metallic contraction joint, also known as non-metallic compensator and fabric compensator, is a kind of compensator. The data are mainly fiber fabrics, rubber, and other high-temperature resistant data. It can compensate the vibration of fan and air duct operation and pipeline deformation.
1、 Use of non-metallic contraction joint:
The non-metallic contraction joint can compensate the axial, transverse and angular directions. It has the characteristics of no thrust, simplified support design, corrosion resistance, high temperature resistance, noise elimination and vibration reduction, and is especially suitable for hot air pipes and soot pipes.
2、 Connection mode of non-metallic contraction joint:
1. Flange connection
2. Receiving connection
