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 ?: 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: 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...

Do you know how clockwork toys work?: Clockwork toys use constant torsion springs made of stainless steel coils. An external force rewinds the spring to the output wheel (energy storage) from its natural state. When the force is removed, the spring returns to its natural state. At the same time, a constant torque (stored elasticity) is generated (released) at the output wheel, hence the term constant torque spring. The torque is greatest when the barrel is fully wound so that the front end of the barrel needs to be output with less force. After a certain period of time, the winder, which is tightly coiled on the winding shaft, will slowly unwind and its energy will drop. When the energy is about to be exhausted, the torque at the end of the barrel is at its minimum and the force output is then reduced. Thus, the driving force needs to be increased to keep the movement running. This is why constant torque springs are so suitable for wind-up toys.

Add constant force spring in the mechanical arm to make it more stable: Adjustable mechanical arms are commonly used in offices, laboratories, studios and other locations to support objects at various angles and heights, such as lights, computer screens, laboratory instruments, microphones, etc. The adjustable manipulator consists of a base member and two connecting rods connected through a pivot joint, which are held in place by friction in the joint. By using spring assisted balancing devices that compensate for most of the weight, the amount of friction required to keep the equipment in place is reduced. The pivot is a connecting ring that can rotate around an axis set at the pivot point, and a way to attach a spring to the pivot point to reduce the amount of force required. Apply to the arm to place the supported object in the desired position. The auxiliary balance device uses a constant force spring, because the constant force spring provides a smooth range of motion and a constant load in the extension or retraction direction. This can provide smooth motion and force requirements that predict the smallest detail, and the force applied by the constant force spring is more constant over the entire range of motion of the two arms of the device. If coil spring balance is used, a constant force may not be applied to the supported object at all positions of the upper arm part and the lower arm part. For example, at the far end of the range of motion, usually, the force applied to the supported object is insufficient or too large, making it difficult and troublesome to place the...

Application design of constant torsion spring in bicycle nest: The bicycle nest is an automatic lifting device for bicycles, which is placed on the ceiling of the room and can be stably raised and stored on the roof. It can safely accommodate any bike, no matter its shape or size. The storage method is simple. If you need to get on the bike, gently pull on the loose rope, then push the bike down and the bike will be lifted.

[Qianye precision]Spring on motor car curtain: When taking the high-speed railway, everyone should like to look at the scenery outside the window. I don't know if you have paid attention to the curtains on the bullet train. When I take the bullet train, I often find that there is no buckle on the curtain slide rail on the bullet train, but I can still go up and down freely and won't fall or bounce back. That is to say, when I pull down 1 / 3, it will stop at 1 / 3, and when I pull down half, it will stop at half; If you want to put it away, just push it up and stop where you push it? It's different from the curtains I usually see at home. Isn't it affected by gravity? With this curiosity, let me show you that the bullet train should be a spring roller shutter. The elasticity of the spring roller shutter can adjust the rise and fall of the fabric within a certain range and can stop at any position. Gently pull down and let go. The fabric can bounce back to the top of the curtain leisurely and freely. The operation is light, the operation time is short, and the stay position is arbitrary. Compact structure, flexible and convenient operation. Because the addition of variable force spring makes the roller shutter achieve this effect, many variable force springs on the market can not achieve the effect that the force is changing in any section, so many electric roller blinds will add some components (deceleration device, damping device, this...

Traditional power springs and preloaded springs: 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...

Do you have this problem when designing cordless blinds?: When the curtain is pulled to the top it sags and when it is pulled to the bottom it springs back a certain height. Qianye Spring Company has succeeded in developing this cordless blinds spring. The steps in the design of a cordless curtain spring are as follows. 1. Determining the size of the winding spring force It is usually necessary to determine the weight of the curtain. It is usually possible to measure the force required to hold the cordless curtain at the top and to measure the force required to hold the cordless curtain at the bottom. Determining the spring life It is usually necessary to determine the duration of use of the curtain. For example, a spring with a life of 8,000 strokes will not loosen or deform within the life of the spring. Determining the space in which the spring is to be installed The space where the spring is to be placed, the distance between the two springs, the outer diameter of the spring, etc. should be taken into account. 4. Adjustment of the curtain spring after trial This stage is usually the adjustment of the force. For example, increasing the force of the spring at the beginning or decreasing the force of the spring at the end.

Congratulations on the return of Shenzhou 13 spacecraft: At about 10 am on the 16th, the "Shenzhou 13" manned spacecraft landed smoothly, and the three astronauts who had been on a business trip for half a year also returned safely, and the hearts of many people also fell to the ground. At the same time, Yang Liwei's voice that appeared in the live broadcast room also made many people's soul wear 2003. Recalling that when the "Shenzhou V" was successfully launched in 2003, the first batch of post-90s generation was just thirteen years old. "Shenzhou No. 5" may already be a term with a sense of age for the late-born children of Generation Z and Generation Alpha. Mankind's curiosity and desire to conquer space have never stopped. What does the vast universe look like with human naked eyes? Is it really romantic and exciting to be in space as outlined in science fiction films? Is space really desolate and silent? Because outer space is full of all kinds of mysteries, human beings may be afraid to see the deep universe in outer space, especially when they float in outer space when they get out of the cabin. Therefore, when the astronauts leave the cabin, they are tied to the astronauts with an 18 meter long rope and connected with an oxygen pipe to provide life support for the astronauts. If the astronauts do not grasp and drift, they can use this rope to return to the space station. Fortunately, our Qianye precision has also made a small contribution to the national aerospace industry. We are mainly involved in...
