Q: Hydraulic diagram of the one-way valve has two kinds of drawing, with a spring, without a spring, what is the difference between automatic reset function is not? Without a spring, it will not be repeated: Certain large diameter one-way valves have no springs, and steel balls rely on gravity return. These valves usually require vertical mounting.In fact, in the oil flow driven, the ball will always reset, no spring one-way valve can also be closed. Only the closing action has hysteresis, better than the spring back reliable.

Q: What is spring pressure and height?: Press the compression spring to the point where each circle is tightPress height = = (total coil number -0.5) * steel wire diameter

Q: What's the spring material to?: 65Mn, 55Si2Mn, 60Si2Mn, 50CrVA, 75, 85, 55CrMnA, 60Si2CrVA, 60Si2MnA, 70, 65, 50CrMo, 55SiMnMoVNb, 60SiMnMoA, 65Si2MnWA, 70Si3MnA, and so on

Q: Can springs be used for support?: If there is a condition, the upper and lower parts of the spring are mounted, similar to the bearing parts, and more thoroughly separated from the gears.

Q: What is an independent bagged spring?: Independent spring: there are different springs, respectively, according to different weight, set up independent spring in different locations. Of the two men lying on it, one rolled over or left, and the other was not affected at all. Two mattresses in the middle area, the spring has different support strength, so won't feel sleep in the two bed crevice.

Q: What kind of spring has the best performance?: Spring verticality, verticality is bad, will directly affect the strength and life.

Q: The shop glass spring door is too tight, how to adjust?: The spring of the stainless steel cover apart, there are 3 word brass wire, a label is in the middle of the elastic adjustment, Zuo Song left right tight, elastic, elastic, dextral (clockwise) that don't mix too much, a little bit, take it for a test drive, if you do not have the best mark pen in a gong wire above the mark, next to the two speed is adjustable,Note, the label ripped open, there will be no warranty, and all gongs silk must not be twisted out, only minor adjustments

Q: How to distinguish between spring steel and stainless steel: Stainless acid resistant steel, or stainless steel, is made up of two parts: stainless steel and acid resistant steel. In short, steel that resists atmospheric corrosion is called stainless steel, and steel resistant to chemical corrosion is called acid resistant steel. Spring steel is a quality carbon steel, but it can rust.

Q: In short, in vibration and wave, it is not easy to make mistakes when we grasp the difference and relationship between "displacement" and "displacement relative to the balance position": In short, in vibration and wave, it is not easy to make mistakes when we grasp the difference and relationship between "displacement" and "displacement relative to the balance position"

Q: The glass door spring is broken. How much would it cost to change it?: The ground springs are not expensive, they are artificially expensive. It won't cost more than 300 yuan, depending on where you are. For example, 180-220 people will do it in the county. In the township, then you do not want to do aluminum alloy will not exceed 200
