The spring used in the spring shock absorber must meet those requirements, while the spring used in the spring shock absorber must meet those requirements. First of all, the spring must meet the following conditions: under rated load, the radius of the spring must be greater than four times its height; the spring must have a certain additional stroke, which is at least equal to 50% of the rated static deflection.

The number of spring coils should not be too small, generally no less than six turns; the spring made in this way can ensure that the horizontal stiffness of the shock absorber is large enough, so that the shock absorber is stable and not easy to fall down, and the elasticity is long-lasting to ensure the long-lasting damping capacity. However, the price of the spring shock absorber is often higher. It should be pointed out that the spring shock absorber is very popular in the market at present. It completely hides the spring inside the shell and can not directly see the state of the spring from the outside. That's a bit incorrect! Because of this "after time", if the spring is seriously corroded, the administrator will not be able to find and replace the spring in time. The spring may break, the pump will sink, and the line will break.

Although the price of this spring shock absorber is slightly lower, please do not use it. According to the reasonable selection of the pump weight, the spring compression after the weight of the spring shock absorber pressure pump should be greater than 20 mm, not exceeding the rated compression of the shock absorber, so as to ensure the best performance and vibration isolation effect of the shock absorber.
