How long can the spring last?

Heure:2022-9-14

How long can stainless steel springs last? This is a common problem. You might think that as long as it's not stretched beyond the point of recovery, the spring will always return to its original shape. A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials deform under the action of external force, and return to their original shape after the external force is removed. Also known as "spring". Generally made of spring steel, the types of springs are complex and diverse. However, spring life depends on many factors.         1. Spring design Are they properly designed for their intended purpose? Many are not, errors in spring design are the main cause of premature spring failure. When choosing a spring, remember to pay attention to what it is for and how it will be used. Is spring strength more important or elasticity? If you're not sure, experts can help guide your decision.       2. Quality of manufacturing materials       The life of the spring is also related to the quality and modulus of elasticity of the materials used in its manufacture. Make sure your springs are made of the best quality material for the desired application. For example, stainless steel springs have high strength, low stress relaxation, corrosion resistance and heat resistance. However, their performance decreases at sub-zero temperatures.       3. Application pressure and environmental conditions       If the force applied is greater than the spring is designed to withstand, fracture may occur....

Motor brush spring and wind turbine maintenance

Heure:2022-9-14

Research shows that to get the greatest return from turbines, whether onshore or offshore, the bigger the turbine, the better. Wind turbines have proven to produce reliable and pollution-free energy, and as technology innovates, the cost of developing and manufacturing them will only become more affordable.  Motor Brush Materials and Wind Turbine Maintenance     Motor brushes are consumables, which means there is significant wear and tear over time and will need to be replaced. While proper wind turbine operation and maintenance requires moderate wear, excessive wear can create carbon dust in the slip ring cabinet, reducing internal isolation.      Also, a useful tip to keep in mind is that motor brushes that are evenly worn indicate good performance. Since reliability is critical in wind applications that generate electricity for industrial tasks and homes, businesses and schools, it is important to work closely with your engineers and parts manufacturers to determine the best motor brush materials. Two common options include: Copper carbon brushes are very common and affordable. They can be used for up to two years, but due to the high amount of carbon dust, they need a lot of maintenance. On the other hand, silver motor brushes are more expensive, but cleaner, can withstand harsh weather, and can be used for up to five years. Slip ring compatibility and design is another component to consider. Although there is wear, your motor brush must maintain a stable surface finish to avoid overtime affecting the performance of the brush. Due to the high cost of repair or replacement of wind...

Advantages of Qianye power spring in electrical take-up

Heure:2022-9-14

As we all know, take-up spring can help take-up. It is used in many electrical products, and hair dryer is no exception. However, all such household appliances have a common feature, that is, they need a wire group to connect the power supply. However, this power line will bring some trouble to our sorting. The function of winding up lies in this. It can bring a free shrinkage process to the electrical wire group and make its winding up easy and practical. In fact, although the process of electrical wiring is not a high-end principle, it is better than cleverness. Its working principle is not complicated. It uses the spring box to limit the outer diameter, so that the center of the spring is connected with the power shaft. When the line is pulled out, it can make the shaft and the spring rotate relatively, and the spring will roll on the power shaft and store the corresponding kinetic energy. When the external force disappears, the spring will generate torque to drive the power shaft, so that the line can be retracted back into the box. In the take-up function of the reel, the effect of the power spring can not be underestimated. It can often help the required goods to take up the line quickly and simply, and become an auxiliary software favored by people. It is also due to the spring to store kinetic energy. It uses the characteristics made by the spring bearing force, and effectively uses its mechanical energy storage and driving force output, so that...

Ressorts de puissance utilisés dans les systèmes de démarrage à rappel

 Small engines are well known and are commonly used in lawn mowers and garden tractors and various other garden and lawn maintenance tools, in addition to other environments. Typically, each of these engines is equipped with a recoil starting system that includes a rope that rotates the starting mechanism to engage a flywheel that is connected to the engine for starting purposes. Once the rope starter is pulled, the recoil mechanism is always provided with the engine to reel the starter rope back to the starting mechanism.   The recoil portion of the starter mechanism is operated by a power spring that tensions when the operator pulls on the starter rope. Once the rope is fully pulled, the operator releases it. Most power springs on the market often fail, so the recoil rewinding mechanism needs to be disassembled and the spring replaced. And replacing the spring is a tedious task because the operator needs to keep the spring in the cavity inside the recoil starter pulley and then coil the spring into the pulley mechanism while keeping the spring in the coiled position and under sufficient tension. Such a procedure requires not only skill, but sometimes infinite patience. That's why the quality of the power spring is a top priority - after all, no one wants to change the power spring inside too often.   Shenzhen Qianye Precision Metal Co., Ltd. was established in 2006 to supply high-quality stainless steel springs for many fields. Through continuous efforts, 20 patent certificates and 4 spring equipment software copyrights have been granted by the State Intellectual Property Office, and an enviable...

Application du ressort à force constante dans les équipements médicaux

Time:2022-9-3

 A support device for assisting a patient is used to assist the movement of a patient at the patient support device. In the prior art, a caregiver would operate a patient lift or motor by guiding the lift to raise or lower the patient at the patient support. Such manipulations often require the precise manipulation of heavy forceps and motors by a paramedic to help the patient move around the patient support.        The support means may incorporate a constant force spring design, the support structure comprising a base and an upper portion extending upwardly from the base. The constant force spring assembly may include a carrier slidably coupled to the base secured to a first end of the carrier. The base may include channels that guide sliding movement of the carrier relative to the base of the support structure. The constant force spring assembly may also include a spool and a motor configured to drive the spool. The auxiliary belt may be secured to the spool so that the auxiliary belt is wound and unwound from the spool in response to a motor driving the spool. And the motor can be fixed to the carrier to move with the carrier.        Constant force springs get their name because their motion force is constantly applied. The load is determined by the width and thickness of the material and the diameter of the coil. The tightly wound rollers work in a linear motion, not obeying Hooke's law (F=kX), but constantly generating forces as they deflect.These springs provide...

Types of Springs in Medical Devices

Heure:2022-9-14

Springs are integral components in the manufacture of many medical devices. Whether it’s for a surgical stapler or a medical monitor, the types of springs in medical devices are defined by a specific action or movement required for the application. Though relatively simple in its design, springs store the mechanical energy necessary for a wide range of medical devices, machinery, and equipment to function properly. Any type of surgical instrument, medical equipment or device that has a mechanism undoubtedly has a spring component. Spring material must be medical grade, and the design and function of any device must adhere to stringent regulatory requirements and guidelines as defined by the FDA. Booms, table and bed lifts, fluid control devices, wheelchairs, medical testing and monitoring equipment either fixed or mobile, MRI and X-ray machinery, dental x-ray with articulated arms, medical equipment drawer closing mechanisms, anesthetic infusion devices, sterilization valves, various implants, and shunt valves are all examples of medical devices that require springs to function. Manufacturers of medical devices and devices subsequently relied heavily on springs in a variety of applications. The medical industry relies on the same types of springs that most industries rely on—constant force springs, constant torsion springs, power springs. Constant force spring Constant force springs are coiled with stainless steel tape so that when coiled relative to being stretched, the spring relaxes in a low stress state. When it is unrolled, the restoring force comes mainly from the portion close to the unwinding spring coil. The resultant force is almost constant. The actuators that operate in the surgical...

Application d'un ressort de balai de charbon dans un porte-balai à bague collectrice d'éolienne

Heure:2022-9-14

In order to prevent accidents caused by excessive wear of the carbon brushes on the collector device of the slip ring brush holder of the wind turbine, a normally closed switch-type alarm unit is configured for each carbon brush, and these alarm units are connected in series to the alarm. In the prior art, the grounding brush is held on the structure using a coil spring pressure finger lever structure. In order to ensure sufficient pressure after the carbon brush is worn, the initial pressure of the spring has to be increased, which aggravates the wear of the carbon brush. However, in the later stage of carbon brush wear, the tension of the coil spring becomes insufficient again, resulting in poor contact between the carbon brush and the slip ring, frequent beating, resulting in breakage; at the same time, from the carbon brush to the alarm unit, the intermediate link is complex and easy to Lead to false alarm or no alarm, reducing the reliability of the system. In order to overcome the shortcomings of the prior art, a novel slip ring brush holder collector of wind turbine generator with simple structure, reduced wear of grounding carbon brushes and reliable operation is provided. The slip ring brush holder collector of wind turbine includes slip ring, brush holder, main carbon brush and grounding carbon brush, and the pressure end of the grounding carbon brush with alarm pressure piece is pressed by a coiled constant pressure spring. The constant pressure spring grounding brush holder structure greatly improves the force on the carbon brush during operation and...

Application of variable force spring in electric roller shutter

Heure:2022-9-14

The electric roller shutter has many advantages, such as beautiful and simple appearance, firm and durable structure, etc. the roller shutter is suitable for a variety of places, such as business office buildings, hotels, restaurants, offices and homes (used as gauze curtain), especially for large-area glass curtain walls. When the roller shutter fabric is put down, it can soften the indoor light, avoid the trouble of direct sunlight, and achieve a good sunshade effect. When the roller shutter is raised, its volume is so small that it is not easy to be detected. Have you ever thought about why the roller shutter will automatically rise and fall, and can freeze at any position without running up or down? You may not have an in-depth understanding, because the addition of variable force spring makes the electric roller shutter achieve this effect. The electric roller shutter extends from the longest to the shortest, and the weight of the lower beam changes from light to heavy. Therefore, the elastic force of the variable force spring needs to gradually increase from small to large, reaching the full stroke and gravity balance. So that the curtain can stop and hover at any position. Many variable force springs on the market can not reach the variable force spring whose force is changing at any section, so many electric roller blinds will add some components (deceleration device, damping device, gear device, limit device, etc.) to achieve the effect of perfect lifting, free positioning and free pause. Qianye often contacts with some foreign curtain industries, especially in cordless curtains and roller blinds, which...
