How to Harmonize the Elasticity of Spring Shock Absorber in Automobile
It is known that the spring shock absorber plays an important role in the automobile, and this role will not cause the automobile to be too stable or easy to be damaged during driving. However, the elasticity of the spring shock absorber is a very critical problem. If the elasticity is not well adjusted, it may directly cause the automobile components to be damaged by vibration or spring.
The greater the damping force of the spring damper, the faster the vibration will be eliminated. However, excessive damping force will lead to the failure of the elastic element to play its role fully, and even excessive damping force may lead to damage of some connecting parts and frame.
In order to harmonize the elastic element and the shock absorber, the following requests are made for the shock absorber:
1. During the suspension tightening stroke (the stroke when the axle and frame move close to each other), the damping force of the shock absorber should be small, so that the elasticity of the elastic elements can be fully applied to mitigate the impact;
2. In the suspension stretching stroke (the stroke that the axle is relatively far away from the frame), the assembling force of the shock absorber should be large, so as to reduce the vibration quickly;
3. When the relative speed between the axle (or wheel) and the frame is too high, the shock absorber should be able to automatically increase the cross-sectional area of the fluid flow channel, so that the damping force is always within a certain limit, so as to avoid being subjected to excessive impact loads.
At present, two-way acting cylinder shock absorbers are widely used in automobiles. The shock absorbers that can reduce vibration in both the tightening and stretching strokes are called two-way acting shock absorbers. Another kind of shock absorber only works during the stretching stroke. It is called one-way shock absorber.
In fact, many times the car runs on a too smooth road. When cornering, the spring shock absorber is constantly maintaining the car, making the car tilt to a certain extent, but not roll over. This is the spring shock absorber working.

Three secrets help enterprises win in pneumatic butterfly valve industry
With the recession of the American economy, many pneumatic butterfly valve factories are ready to tighten their belts in the coming year. Experts are calling for slowing down the economic growth, and the pneumatic butterfly valve industry will also see more mergers and acquisitions in the coming months. Many pneumatic butterfly valve factories were listed for sale because they could not obtain ideal sales, did not use advanced technology and procedures, and never sorted out their own financial departments. Such enterprises would close down sooner or later and withdraw from the stage of history.
However, there are also some good news that are relatively beneficial to the industry. With the closure of those marginal pneumatic butterfly valve factories, many customers have to look for new pneumatic butterfly valve factories, so those surviving pneumatic butterfly valve manufacturers have the opportunity to improve their sales and show their value to new customers. Customers still have a very strong demand for pneumatic butterfly valves, and with the reduction of selection, the surviving pneumatic butterfly valve plants will be able to better control their procurement process.
Approach 1: Establish a reasonable price system
Why are so many pneumatic butterfly valve factories closed? Many enterprises have the problems of lack of funds and business saturation, and they often position themselves as a low-cost consumer selling ordinary consumer goods, which directly led to the failure of their marketing strategy. When consumers began to purchase pneumatic butterfly valve services from the surviving pneumatic butterfly valve factory, they also hoped to pay higher prices for this, because they once realized that a pneumatic butterfly valve factory can only sell high-quality products and services on the premise of making money.
The professional buyer organization once conducted a survey on its members, and the result was that 60% of the respondents thought that the price of pneumatic butterfly valves in 2008 would increase by 3% compared with 2007 (affected by raw materials, energy and other costs), and 17% of the respondents thought that the price of pneumatic butterfly valves would increase by more than 6%.
Pneumatic butterfly valve customers will continue to bargain with the pneumatic butterfly valve factory, but they obviously have not much room for bargaining, because the pneumatic butterfly valve factory that implements the low price policy has been eliminated by the market. The remaining pneumatic butterfly valve factory needs to develop a more profitable price system. Customers have seen the experience of those low-cost pneumatic butterfly valve factories - they have embarked on the road of death.
Those pneumatic butterfly valve factories that can help customers relieve pressure and meet the challenge will have higher value, and customers are willing to pay higher prices for value-added services and profitable products.
