 Primavera di potenza
Primavera di potenza
Characteristic: The power spring is coiled by steel strip. A spring box is required to limit its outer diameter. The center of the spring is connected to the shaft. When an external force is applied to make the shaft and the spring rotate relative to each other, the spring will be wound on the shaft and stored Torsion, when the external force disappears, the spring generates torsion on the shaft or spring box. Advantage: Power springs are divided into natural power springs and pre-stressed power springs according to their relaxed shape. In contrast, the pre-force type power spring can store 25% to 55% more torque and provide more effective turns. Product manufacturing range: The thickness is 0.05~0.85mm, and the width is 2.0~60mm. Principle of the scene: The high-precision pen injector uses a unique power spring to provide small and highly accurate drug dosages. A fixed amount of medicine is injected into the body through the constant force of the spring...

Characteristic: The fixed (constant) torque spring (spring) is made of stainless steel. The external force rewinds the mainspring from its natural state to the output wheel (energy storage). When the external force is removed, the spring will return to its natural state. At the same time, a constant torque force (stored elastic force) is generated (released) on the output wheel, so it is called a constant torque generator. strip. Belongs to (a use method in constant force spring) Advantage: The advantages of fixed-torque springs compared to power (scroll) springs: 1. The torque will not change due to the increase in the number of revolutions. To 2.

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...

 Do you know the principle of medical cart?
Do you know the principle of medical cart?

Ora: 14-9-2022

During the normal operation of the hospital, it is often necessary to use the medical cart. The medical cart refers to the ward protection and transfer of medical equipment. The medical cart prevents the patient from causing further injury in the process of transporting the patient. At the same time, it also reduces the labor intensity of medical staff or family members. It is a commonly used medical device. At present, the medical cart on the market can only be used in the process of lifting the patient from the hospital bed to the cart or from the cart to the hospital bed, The scope of use is narrow, which is easy to cause a waste of resources and the problem of single function. Therefore, a medical multifunctional cart is proposed to solve the above problems. The medical multifunctional cart has simple structure and convenient operation. It can be used as a medical cart under normal working conditions. Drugs for medical use can be placed in the medicine box, and medical waste generated in the medical process can be placed in the garbage box. The turnover cover plate can close the garbage box to prevent the garbage in the garbage box from shaking or overflowing due to the movement of the cart. The operator rotates the rotating rod and turns the connecting rod and pulley out of the shell, When the pulley is in contact with the ground, the operator pushes the cart, and the cart can be moved freely with the help of the pulley. When the hospital lacks...

       Conventional motor arrangements include a rotor with windings to conduct current during machine operation. As the rotor rotates, current is conducted through the rotating elements from sources external to the rotor to the rotor windings. A rotating element such as a slip ring or a commutator contacts the brush spring to conduct current.        There are two main types of brush springs, single-coil brushes and double-coil brushes. The brush springs provide constant pressure to the commutator and slip rings while minimizing brush wear, burning and scratching. They provide excellent work at high speeds for improved motor performance. The brush spring is relative to the rotating element, and the brush spring is ground due to friction during use. It is damaged and needs to be replaced periodically. So sometimes the brushes are replaced during motor downtime. To change the brushes safely, the operator uses one hand (to avoid current passing through the operator's body). Brush carriers can be heavy and unwieldy, so brush replacement is not only difficult but dangerous.        A brush holder, brush handle assembly helps operators safely remove replacement brushes in electric machines or other rotating machines. A stationary support is included having at least one groove and a pronged electrical connector. The stationary support has a conductive strip for a portion of the body for being configured to pass through the stationary support. Its lead electrical piece is configured to provide electrical conductance with a collector base (collector base) and electrical fork connectors.        The brush retention structure...

Constant force spring is made by winding the steel strip into a coil. The stress added to the spring determines its diameter, strength, and life. The action of a constant force spring is very similar to the action of stretching a ribbon. Spring stretching and rewinding, the part of the work with the spring itself circle formed tangent, as long as the diameter of the spring is certain, the force of the spring is constant. In extremely long spring designs, varying diameters have an advantage, and the tension increases slightly as the spring is stretched. However, this increase is small relative to the length of the stretch and can be ignored in many applications.Constant force spring is made by winding the steel strip into a coil.

Today we're going to talk about the connection between the constant force/tape spring and the tilting double or single hung window.   As we know, hung windows feature a balanced application to counteract the weight of the sash, allowing the user to position the sash at the desired opening height. The balanced application also enables users to open and close windows with minimal effort.   Actually, the constant force/tape spring is a somewhat hidden component sitting inside the window frame of the tilting double or single hung window, it is the balanced application, sometimes called a sash balance, window spring, or window "balancer".   Window balances are only found in double-hung or single windows and counterbalance the weight of the sash assisting you with opening and closing your windows. If your window balances are damaged or broken, your window may be difficult to open, not open at all, or may not stay open.   Qianye Springs (Qianye Precision Spring Technology Co., Ltd) provide the high-quality constant force/tape springs. All our springs are made of 301 stainless steel which ensure the springs are durable and long-lasting.     More info:https://www.qianyespring.com/ mail: leah_lee@qianyejm.com Whatsapp: +86-181 7563 3483
