Rise with the development of economy, the automobile industry, and other machinery manufacturing industry development, shock absorber industry is rapid development, in the market to occupy a place, but some manufacturers are not professional testing equipment, resulting in the production of inferior products. Today, our Yuhuan Feng Rubber Product Factory to teach you to choose the shock absorber.
One, look at the shell
The shell is a component of vibration reduction, perennial load, security is essential to the strength of a high demand, there are two kinds of misleading customers on the market tendency:
1, in order to raise the price of a shock absorber, to the shock absorber with beyond the normal requirements of the shell, such as big box body with a small spring, very funny, customers may paid beyond the scope of the normal price is several times the price, greatly increasing the cost of engineering.
2, one is to reduce costs, the shell is particularly thin, for example, thick, apparently can not be tested by no deformation. Directly can be judged as substandard products.
Two, look at the spring
1, if the spring ends tight and smooth, not smooth and tight will affect the stability of the vibration damper.
2, the national standard requirements of the compression of the shock absorber, such a reduction in the amount of compression to ensure that the natural frequency of the vibration absorber is low enough to ensure the effect of vibration.
3, some manufacturers in order to save costs, but also to meet the requirements of the load, the spring will do a lot of stiffness, spring compression in the nominal load is very small.
In accordance with the requirements of this standard, most of the vibration damper on the market are not qualified. Customer purchase must pay attention to the compression of the spring.
Three, look at the surface treatment
(1) at the surface and the shock absorber spring surface treatment, paint is peeling off,
(2) welding is smooth, whether there is slag.
(3) whether the smell of paint, poor quality paint has irritating smell, high toxicity, in the indoor installation will cause long-term harm to the human body.
Four, the regular manufacturers are not high prices
The simplest method is to choose the big brands, big manufacturers products, usually have a formal test report, certificate, quality assurance, the market competition is intense now and large manufacturers have advantages of scale, small profits and quick turnover, product price is not high, such as Hanwei series and Ann Lijing series of shock absorber, quality and cheap, quality assurance. |
