Methods to prevent premature corrosion of springs

We often use springs in our daily lives, but due to chemical and electrochemical reactions, the contact surface of the spring will be corroded to varying degrees, causing damage to the spring and affecting the functionality of the equipment. How should we avoid premature corrosion of the spring? There are three anti-corrosion methods for spring: painting, oxidation, and electroplating. Their anti-corrosion principle is to form a protective layer o

Calculation of tensile strength of irregular springs

The tensile strength refers to the load change per unit of deformation, usually expressed in pounds per inch (lb./in.) or Newton per millimeter. The requirements and scale of load and deformation determine the stress of the spring. When a load is applied to the compression spring, the spring generates stress on the wound coil during the twisting process. The maximum stress on the surface of the steel wire; As the deformation of the spring changes, the load also changes, which leads to the emergence of operational stress planning

In the future, at the level of "conservation of mass and energy", the spring will definitely become heavier and meet the potential energy Ek for spring progress (or stretching)=Ek=Δmc^2, such changes alone are very subtle. The mass energy equation states that any change in the energy of a closed system will result in a change in the relativistic mass, in order to satisfy the conservation of mass and energy. At the microscopic level of compression (stretching) of s

The difference between stainless steel springs and spring steel springs

The strength of the vortex spring steel wire can be reached, and it can be used to make spring, as well as to manufacture manganese based phosphating coated steel wire ropes, etc., with excellent strength and durability. The strength of stainless steel wire is generally much lower than that of carbon steel wire, but stainless steel wire has excellent corrosion resistance. Use a hacksaw to stagger a notch, and if copper color is found, it is stainless steel with nickel plating. Otherwise, it would be stainless steel

Spring Factory Teaches You How to Distinguish the Rotation Direction of Springs

The application of springs is becoming increasingly widespread, but many people simply need springs; Many people probably don't know how to distinguish the rotation direction of springs. The spring factory tells us how to distinguish left and right rotating springs: The spring produced by the spring factory has the same left and right rotation as the left and right hand screws. If it is a tightening spring, the left and right rotation are the same

Two Methods for Manufacturers to Harden Compression Springs

The two ends are open, closed, or flattened or ground, and their shapes are diverse. When subjected to external loads, they will shorten deformation and transform into variable functions. Compression springs can be applied in multiple fields, such as electronics, computers, cars, compressors, and other professions, highlighting their effectiveness. Compression spring is a hardware accessory composed of several spiral shapes formed by lines, making

Method for stress testing of irregular springs

Spring are a general term for hook type, straight hook type, combination type, and multi coil type spring. Irregular spring can be made directly with a spring machine. The so-called irregular spring means that its shape is irregular, nor is it singular in shape. Regarding special shaped spring with the same structure, under the same load effect, there is a significant difference in the results obtained by the two methods for the stress of spring s

The elasticity of the spring determines the safety of the safety valve

Spring type safety valves rely on the elastic pressure of the spring to lock the valve's valve or plunger and other seals. Once the pressure in the pressure vessel is abnormal, the high pressure will defeat the spring pressure of the safety valve, so the locking device is pushed open, causing A pressure relief channel is provided to release the high pressure. According to the different opening height of the valve disc, it is divided into two types: full lift type and micro lift type. The full-lift type has a large discharge capa
