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...
How to make the constant force spring produce more force
How to make the constant force spring produce more force
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...

 Spring to ensure good elastic performance, that is, absorb a lot of elastic energy without plastic deformation; Sufficient plasticity and toughness to prevent impact fracture. According to the stress nature, the spring can be divided into tension spring, compression spring, torsion spring and bending spring. According to the shape, it can be divided into dish spring, ring spring, plate spring, spiral spring and truncated cone scroll spring.       The design process of spring has the following points:      1. Device space: design a compression spring, clearly understand the space required to install the spring, and then you can master the basic manufacturing conditions, outer diameter, inner diameter and free length of a compression spring.      2. Movable stroke load: the design of compression spring to clearly understand the position to be actuated and the elastic force to be carried.

 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...

Car covers are commonly used automotive protective articles, but the folding and storage of car covers is a troublesome thing. In order to solve this problem, invention lovers have done a lot of useful exploration and put forward many solutions. One kind of scheme is to use power to drive the reel to directly roll up the car cover cloth. Using the reel to directly roll up the car cover cloth can achieve the purpose of rapid retraction of the car cover, but there are the following problems in actual use: first, the winding and friction of the reel when directly rolling up the car cover cloth wear the car cover cloth greatly; second, in order to adapt to the width of the car cover cloth, the width of the car cover retracting device must be close to the width of the car cover cloth. If it is too narrow, it will increase the winding of the car cover cloth, so the shape of the car cover retracting device is larger, It reduces the convenience of use: Third, it may not be able to completely stow the hood cloth. Only one power spring is needed to solve the above series of problems. The power spring designed by Qianye precision can be applied to the car cover. The power spring retracts the car cover to realize the rapid retraction of the car cover.

 I'm sure many of you know what a constant force spring is, right? A constant force spring is a spring that maintains a constant spring force for a specific stroke, also called a constant force spring, and is used in a linear motion, usually using its rebound force. A constant force spring consists of a spiral-shaped metal sheet that is bent on the inside so that each coil is wound tightly around the innermost coil of the metal sheet. When the metal sheet is stretched, the internal stress resists the load force, which is exactly the same as a normal extension spring, but the spring force is very constant and can output a nearly linear spring force.   The use of a constant force spring on the lift support enables the supported structure to hover over gravity at any position during the allowable travel.   However, in order to achieve a variety of functions and operations, the supported structure, such as a monitor, usually weighs more than the white body of the device. In order to ensure a large support force, the constant force spring needs to use a thick elastic metal sheet. However, the thick elastic metal sheet will lead to a short effective constant force spring travel.   The purpose of this constant force spring die set is to provide a constant force spring die set that is capable of maintaining a large constant force lift value and a constant force effective stroke within an effective mounting space. Another purpose is to provide a constant force spring lift mechanism that not only provides a greater constant lift force, but also reduces the mounting space of...

The gas station is a familiar place for everyone. Do you find that the lines of the gas gun are all exposed when passing through the gas station or entering the gas station to refuel? They look messy and unsafe. The car needs to refuel, so you have to go to the gas station to refuel. With the continuous growth of car owners, the passenger flow of gas stations is also increasing. Have you seen the news of the gas station explosion? After a car in a gas station was refueled, due to the negligence of the Refueller, the Refueller did not take out the refuelling gun from the fuel tank port, and the driver of the owner did not check the surrounding conditions of the car, so he started the car. Then the car drove the refueling gun and oil line, pulled down the refueling end connected with it, and caused an explosion. This kind of news is very sad. Once an explosion accident occurs in the gas station, it may cause the explosion of the whole oil tank in the station. Its power is very huge, and the personnel in a certain range around may be seriously threatened. It is understood that the lines of gas guns in foreign gas stations use money collection devices. Now there are a small number of applications in China. At present, there is no large-scale application in gas stations. It uses the characteristics of winding up. It can bring a free contraction process to the line group, and make its winding easier...

When you walk into your office building on your way to work every day, or into your local bank, or any commercial facility, you may open a heavy glass door. When you cross the threshold, the door closes behind you, and you don't think about it. However, the heavy glass door was probably closed by a constant force spring. Constant force springs are widely used in daily applications. From door closers to rope and hose retractors, to sports equipment, toys, motors, etc., constant force springs exert force at an amazing high frequency and consistency. Let's take a closer look at the basic physics behind the constant force spring. In the 17th century, the British physicist Robert Hooke proposed a formula for force and elasticity, which is now called Hooke's law. Hooke's law states that the force (f) required to stretch or compress a spring for a distance (x) varies linearly in proportion to that distance. The formula is f=kx, where k is a constant and represents the stiffness of the spring.   Constant force springs in terms of actual spring performance, Hooke's law is nominal. In the equation, the distance X that the spring moves is a relatively small number. Finally, any elastomer that is stretched or compressed beyond the stress limit of its material composition will show signs of deformation. Therefore, the force properties that depend on the consistent shape and tension state will change in the deformation state. Ideally,constant force springs will exert a consistent force over a given range of motion, repeating without changing. In fact, constant force springs, like all elastomers, are limited...

   Traditional power springs and preloaded power springs are fabricated from spring steel bars to provide torque. Spring steel is a low alloy, medium carbon steel or high carbon steel with a very high yield strength. Objects made of spring steel can return to their original shape despite significant bending or twisting. Power springs use flat (unstressed) steel windings, while pre-stressed power springs use pre-stressed steel to produce a larger range of usable torque than conventional power springs.        During the manufacturing process, the spring is wound into the retaining ring or the customer's housing (the retaining ring is pictured below). When ready for final installation, carefully install the spring into its housing with the outer end attached to the outer edge and the inner end attached to the mandrel (see photo below). During operation, the housing or mandrel will be fixed while the other component is free to rotate. Depending on the requirements of your specific design, it may be beneficial to use a fixed mandrel/free box or free box/fixed mandrel arrangement.        These springs are typically used to retract the cord or cable of the spool. You might see it in lawn mowers, retractable lanyards, or dog leashes. This is also the type of spring used to drive many mechanical clocks and timers, which is why they are sometimes called "clock springs". The load provided by the spring increases with the cross-sectional area of ​​the material. The number of turns the spring can provide depends on the space available between the mandrel and the...
