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
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...

As the building access door of modern plant, the industrial door must be familiar to everyone. The industrial door has a variety of lifting door modes. It slides upward according to the track installed on the wall, which is fast and stable. At present, the industrial door mainly uses the torsion spring balance system to stabilize the industrial door in the process of operation, so that it can be opened quickly.   Principle of torsion spring balance system: torsion spring balance is the principle that the weight of the door body is balanced by the torsion torque of the torsion spring. The torsion spring balance system of industrial doors is mainly composed of supporting seat shaft, spring, wire hub, steel wire rope and other components, in which the material of torsion spring is more important. Generally speaking, the torsion spring of the torsion spring balance system needs to be made by computer-aided design and professional equipment.   Industrial door balance system analysis what are the small problems of torsion spring balance?

 When powered by a damped constant force spring mounted on the spool, there are several key principles that influence the design of linear motion applications. These principles support robust and consistent performance of products in a variety of applications, including automotive and aircraft interiors, industrial machine components, and many other user interface applications. The example components shown above will be cited as examples of the various design principles detailed below. This example assembly has a sliding drawer (shown in red) powered by a constant force spring mounted on a spool (spool in green; constant force spring shown in yellow) running within a mounting base (shown in grey), such as a central Console a car. A ratchet or door latch mechanism (not shown) can be implemented to allow the tray to be locked in place with a single press by the user. This example is a typical set of applications used in the automotive industry.        1. Preload spring        When a constant force spring is in its free state, it does not exert any force. As the spring stretches, the spring force rapidly increases from zero to nominal load. However, to avoid including this "accelerated" part of the work envelope, the design can use preloading. An example of preloading is shown in the figure below. Note that although the mechanism is retracted, the depicted spring is extended.        To include preload in the design, ensure that the spring extends a distance equal to the outer diameter of the coil during assembly in order to engage...

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...

  The constant force spring of the industrial door mainly plays a balancing role and reduces the burden on the motor. The force of the spring is equivalent to the force of the industrial door, which is the most ideal configuration state. If the spring force is too large or too small, it will affect the operation of the industrial door. In severe cases, safety accidents may occur and endanger others.        Constant force springs are often used to provide balance to products, so what is balance?        Constant force springs are most useful in applications that require consistent recoil. Ordinary springs behave according to a mathematical equation called Hooke's law. Hooke's law states that the force of a recoil spring in the direction of recoil is equal to the distance the spring is displaced from equilibrium. Simply put, we look at how far the spring is stretched - multiplied by a mathematical constant, the rate of the spring. The recoil direction of the spring is opposite to the stretch direction.        Hooke's Law does not affect constant force springs because their recoil remains constant throughout their range of motion. Their unique design consists of a thin, coiled steel strip that rests when fully coiled. Constant force springs are loaded when they are partially or fully deployed. When released, the spring springs back, pulling the extended ribbon back and rolling up properly. Since the recoil force is mainly obtained closest to the take-up roll, a constant force is maintained. A constant force spring can be...
