Analysis on the causes of carbon brush fault of generator set
Analysis on the causes of carbon brush fault of generator set
In recent years, several safety briefings have successively reported shutdown accidents caused by carbon brush or rotor collector ring failure of large generator units, resulting in great economic losses to the enterprise.Carbon brushes are motor brushes. Improper maintenance and use of the carbon brush of the generator set during operation will cause accident load reduction or even shutdown.        Factors leading to carbon brush fault      Electromagnetic factors : when reactive or excitation current is adjusted, the spark of carbon brush has obvious change. When the exciter commutates, the contact between the carbon brush and the commutator is not good, and the contact resistance is too large ; the uneven thickness of the oxide film of the rectifier or slip ring causes the unbalanced distribution of carbon brush current ; or sudden change of load and sudden short circuit lead to abnormal voltage distribution between commutators ; unit overload and imbalance ; carbon brush selection is unreasonable, carbon brush spacing...
How long can constant force spring be used ?
How long can constant force spring be used ?
Constant force spring, also known as hair spring, is made of stainless steel strip. The force added to the spring determines the diameter, force and life of the spring. The action of constant force spring is similar to that of stretching ribbon. The spring stretches and rolls back, and the working part is tangent to the spring ' s own circle. As long as the diameter of the spring is certain, the force of the spring is constant. According to the application principle of constant force spring, constant force spring can be divided into linear constant force spring and rotational constant torque spring. When linear stretching force units are : kg, Newton, pounds, etc.     Then how long can the constant force bar be used ? The life of the constant force bar is limited, and the life requirement of the spring should be considered when designing the constant force bar. This step is important because it affects the...
Wie man die Feder mit konstanter Kraft dazu bringt, mehr Kraft zu erzeugen
Wie man die Feder mit konstanter Kraft dazu bringt, mehr Kraft zu erzeugen
A common way to install a constant force spring is to use two or more springs to obtain greater force in a narrow space. This may be necessary if the diameter or width of a single spring exceeds the allocated space, but there is room to add multiple smaller springs. When engaging multiple springs, a much smaller spring design can be used. The total force is the sum of the spring forces.       When combining springs, it is recommended to use the same spring for multiple installation. Compared with using two or more completely different springs to realize the load, this method is more economical and the design will be simpler. Since the force is the sum of the springs, the total force required should be evenly distributed between the number of springs used. We will discuss three different mounting methods for use with multiple springs.         1、 Back to back method The back-to-back method uses two...

How to determine the length of a constant force spring
How to determine the length of a constant force spring
  Constant force springs are mechanical devices used in applications that typically require some kind of balance or retraction mechanism. In design and function, constant force springs differ from the more common types of coil springs. They apply a consistent linear force or torque that remains constant over a wide range of motion. When a coil spring is under force, whether it is stretched, compressed, or rotated, it produces a force proportional to its stretch. How a spring responds when a force is applied or released is called spring deflection. Years of experience tell us what happens when a spring is released from its temporary state. We know that the spring will return to its original position, but it will be proportional to the force exerted on it before releasing. A spring has a restoring force that allows the elastic material to return to its original state - the equilibrium position after the applied force is removed. Stretching, squeezing or twisting, what...

 Design and manufacture a complete set of constant force springs for a variety of applications in almost all industries, from medical care to aerospace and general household products. The constant force spring is different from the traditional spiral wound spring. They are made of pre tensioned high-yield metal strips (usually stainless steel) rather than wires. Constant force springs are classified as "tension springs". When winding, the metal strip resists uncoiling with nearly constant resistance. When extended, the internal stress of the metal resists any load force at a nearly constant rate. Once the spring extends to a length of 1.25 times its diameter, it reaches full load and produces a nearly constant force. According to the size of the spring and the load it supports, the fatigue life cycle of the constant force spring is between 2500 and 1000000 times.     Constant force springs are commonly used in automotive engineering, aerospace engineering, medical and retail. Some common applications are: Cable retractor, motor, spacecraft, fitness equipment, door closer, hose retriever, nuclear magnetic resonance scanner, X-ray machine, point of sale display, toys, furniture accessories, retractable tape measure or dog line, retractable vacuum cleaner line, etc.     If you choose a constant force spring for an application, you must first consider several factors. Material selection is important, as is the thickness and width of the metal strip. The most commonly used metal is grade 301 stainless steel because it can make consistent high-quality and strong constant force springs. Other materials are available, such as high carbon steel, Inconel, etc., which may...

 Constant force spring damper
Constant force spring damper

Zeit: 2022-9-14

Dampers are widely used in building structures to dissipate energy and reduce vibration. However, the traditional damper has complex structure, poor durability and corrosion resistance, and low working stability. After using for a period of time, the damper is prone to aging and deformation can not be restored, so it can not be used anymore. Most of the existing dampers use shape memory alloy (SMA), which is a material composed of more than two kinds of metal elements through thermoelasticity, martensitic transformation and its inversion; Using shape memory alloy, the damper can automatically restore to its original shape after deformation, which is used for the restoration of building structures after deformation. However, the existing dampers only use the performance of shape memory alloy (SMA) wire itself, and the cost is expensive, which is not conducive to the large-scale use of dampers.   The design of constant force spring can be added to the self resetting damper. The damper includes piston parts, U-shaped plates and moving rods. The constant force spring is set between the tension moving rod and the pressure moving rod. The constant force spring tightens the tension moving rod and the pressure moving rod to be close to each other, so that the tension moving rod and the pressure moving rod respectively lean against the end close to each other in the corresponding sliding hole. It is conducive to the large-scale use of self resetting dampers. Constant force spring is a kind of functional material with high ductility, which has the advantages of constant load, high energy storage density, low friction loss and so on....

       Springs are an important part of many different industries, including the aerospace industry. They form the backbone of many components and allow planes, drones, satellites, solar panels, aircraft controls, valves, throttles, and more to function their way. Without the spring, the industry would not be the same. Strict military and aviation guidelines mean that all components of the aircraft, including the springs, must be of the highest quality and precision; they support a wide range of applications and reduce part weight while maintaining the highest performance standards. This makes springs vital to the aerospace industry. Without springs, we wouldn't be able to have the essentials of aerospace. For example, retractable tray tables, trunk doors, handrails, stairs and cup holders require springs to function. They help open and close many components that wouldn't exist without them—and, more importantly, springs are some of the main elements of aircraft landing systems. They are also present in satellite dishes and probes that allow navigation and are critical for ground service teams that need to refuel aircraft. You can find springs basically anywhere in the industry, and their absence means that airplanes as we know them don't exist. Part of the reason springs are so important in aerospace is that they are very resistant to compression. Aircraft require robust and durable components that do not require frequent maintenance, upgrades or replacements, but are at the same time extremely precise. Many applications in aerospace require the ability to withstand harsh environments on a regular basis, from aircraft that fly around the world every...
