 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...
 Analysis on the causes of carbon brush fault of generator set
Analysis on the causes of carbon brush fault of generator set

Time:2022-9-15

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 is not equal ; carbon brush quality issues, etc. Mechanical factors : commutator center is not correct, rotor imbalance ; large vibration of the unit ; insulation bulge between commutators or commutators bulge ; carbon brush contact surface grinding is not smooth, or commutator surface roughness caused by poor contact ; the commutator surface is not clean ; the air gap under each reversing pole is unequal ; spring pressure on carbon brush is uneven or unsuitable ; carbon brush in the brush grip too loose and jump, or too tight carbon brush in the brush grip stuck, etc. Reduced operating...
 Fire damper spring
Fire damper spring

Time:2022-9-14

Fire dampers are valves that are used to block the passage of smoke and flame from fires and meet the requirements of fire resistance stability and integrity within a certain period of time. In order to minimize the loss caused by fire, it is necessary to take effective fire and smoke prevention measures to control the spread of fire while the fire damper is ventilated. Reasonable settings in the air conditioning and smoke exhaust system play an important role. The operation of fire dampers is simple: when the temperature of a room or space rises above a threshold limit, they close to prevent the fire from spreading. Fire dampers have fuses and can be selected according to the required temperature. Once this temperature is reached, the damper closes.    The damper itself can be electric, pneumatic or manually set. In electrically and pneumatically actuated dampers, a fuse releases and cuts off the operating voltage of the spring-return motor, causing the spring to close the damper blades. After replacing the fuse and re-establishing the operating voltage of the motor, the fire damper opens automatically. In a spring-operated damper, a fuse release allows the spring to close the damper blade. After replacing the fuse, the fire damper must be manually reset to the open position. Design of fire damper spring:   The advantage of the spring designed by Qianye is as follows: Although Qianye precision can not directly prevent the initial occurrence of fire, we have created customized springs for the life support function of fire dampers. In turn, our spring-loaded dampers provide ventilation...
