Fire damper spring

Čas: 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...

Spring has been very common in people's daily production and life, ranging from planes, trains and cars to household appliances and daily necessities, and even children's stationery for school. It can be seen how important spring is to our life.     What is the definition of spring? It is a mechanical part that uses elasticity to work. Generally made of spring steel. It is used to control the movement of mechanical parts, mitigate impact or vibration, store and measure the size of force. It is widely used in machines and instruments.     For a professional spring manufacturer, the most basic production goal is to infinitely pursue the high quality of products. Therefore, in order to improve the performance of the spring, it is often assisted by pre heat treatment, that is, the process of strengthening the quality of spring steel is used to further strengthen the spring.     In fact, the so-called pre heat treatment is what we often call annealing. It is to heat the steel to a certain temperature and keep it warm for a period of time, and then cool it slowly. Annealing of steel is a heat treatment method in which the steel is heated to the degree of phase transformation or partial phase transformation, and then cooled slowly after heat preservation. The purpose is to eliminate the structural defects of the spring, improve the structure, homogenize the composition and refine the grain, improve the mechanical properties of the steel and reduce the residual stress; At the same time, it can also reduce the hardness,...

Variable force spring in drug delivery device

Čas: 2022-9-14

Devices for automatically delivering drugs, such as automatic syringes, are known as convenient and safe means of protection for patients to manage different drugs themselves. For safety reasons, many devices for delivering drugs include covers and other devices that protect users before and after use, such as injection needles. Different devices for transporting drugs are different in their overall design settings. They all have a mechanism for automatically transferring the contents of pre filled and pre filled containers, and there is no need to manually force the contents of the containers into the patient through the transmission components, namely needles and nozzles. Automatic delivery mechanisms in devices used to deliver drugs usually include compression coil springs. The challenge in the design of such springs is to balance the need for sufficient force at the end of the stroke and the need for less force during storage that will overload other parts of the device (when the spring is fully compressed).   The problems caused by conventional coil springs in drug delivery devices can be overcome by variable force springs. A novel device for delivering drugs, which includes an elastic member (60), a driving mechanism (50), a holding mechanism (40) and a starting mechanism, the driving mechanism has one end connected to a stop and a second end operably connected to the elastic member, the holding mechanism is used to loosely hold the driving mechanism in the first position, where in the elastic member has accumulated energy, The starting mechanism is operably connected to the holding mechanism for releasing the driving mechanism...

Why is the support important for people to face the display for a long time?

Čas: 2022-9-14

What do you think of the correct sitting posture in office? Relax your shoulders, keep your eyes in front, and keep your eyes balanced at the top of the computer or the top 3 / 1 of the monitor. This is the correct sitting posture of our office. To stand our neck, we need a certain height of the display. The horizontal position of the display is low, and the neck is easy to tilt forward. The cervical spine will obviously feel uncomfortable, very tired, and will cause pressure on the muscles of the neck.      The display bracket is mainly composed of upper support arm, lower support arm, display connector and desktop clamp. The most important core lifting components are in the upper support arm, which supports the display through the deformation of spring or air rod structure in the upper arm. When it comes to the spring in the core lifting part, the reason why the display can rise and fall is that it is designed into a lifter that can adjust the height of the display at will by using the principle of free rise and fall of constant force spring. With the help of the tension of the spring, its height can be adjusted freely. Compared with the column support (the lifting up and down is cumbersome, and the screws need to be adjusted by tools every time) it is simpler to use and more convenient to operate after adding a spring. It only needs a little effort to complete the adjustment, which can be said...

Power springs applied in barbell weightlifting protection devices

Čas: 2022-9-14

 Barbell is a kind of core training sports training equipment, which is also used in weight lifting. Barbell sports is a kind of weight training. Barbell training equipment can be used to improve muscle strength training, and barbell can also be used for core training to promote overall coordination. The barbell is heavier than other fitness equipment, which is also prone to accidents. The existing barbell lacks corresponding protective measures when used, which is easy to hurt users or damage the barbell. The above problems can be solved by the power spring. Add the barbell weight lifting protection device of the power spring. The utility model relates to the technical field of fitness equipment, including a base plate, and also includes: a placing table connected with the base plate; Barbell, butting with the placing table; One end of the protection mechanism is connected with the placing table, and the other end is connected with the barbell. The protection mechanism comprises an inductor, a linkage component and a clamping component; The holding mechanism is connected with the barbell. Athletes hold the barbell through the holding mechanism to exercise, and the barbell drives the linkage component to move. When the human body is released, the barbell drives the linkage component to move quickly under its own gravity. When the sensor senses that the linkage component moves faster, the sensor starts the operation of the clamping component, and the clamping component clamps the linkage component, hinders the movement of the linkage component, and then hinders the movement of the barbell, so as to protect the...

Constant force spring for realizing smooth movement of CT scanning table

Čas: 2022-9-14

We are familiar with CT scanner. Now when we go to the hospital for examination, we often hear the doctor say "take a film first". This film generally refers to CT. Doing CT is not only for the safety of patients, but also for the safety of doctors. CT is much clearer than X-ray film. At the same time, there are many diseases that cannot be seen on B-ultrasound and can be diagnosed by CT. At present, CT is the most widely used imaging examination under medical treatment and the most valuable examination for clinical information. When you go to take CT, you lie down on the scanning table, and the scanning table will automatically move smoothly and accurately locate the position. Have you ever thought about this problem because you want to relieve tension? The CT scanner table can move smoothly and accurately because of the role of the constant force spring in it. Some little friends may not know what the constant force spring is. When it comes to the spring, everyone must think it is the traditional linear spring. In fact, it is not. Constant force spring is made of stainless steel strip. The high-strength steel strip is shaped through specific spring production equipment. When it is straightened by external force, the spring will naturally roll back and produce elastic force, However, to achieve our goal, we can return to our designated starting point after the shift. The constant force spring can achieve extremely high elastic output in a very small device space. Its function can be applied to products requiring linear motion such...

Do you know what springs are used as stop mechanisms?

Čas: 2022-9-14

We often find that the spring we make is wrongly used as a stop mechanism in the design. This design defect can occur in all types of springs, including constant force spring, constant torque spring and power spring. For example, consider a simple cable extension product in which the spring retracts the cable into the housing. If the spring is completely wound before the cable is fully deployed, the spring will be used as a stop mechanism. This action will damage the function of the spring and components and should be avoided at all costs. Here are some useful tips when considering the stop mechanism. Constant Force Spring Application:  Initial designs often show the inner end of a Constant Force Spring attached to its’ spool. This is not necessary.  If the spool is larger than the natural spring diameter, the spring will automatically fit tightly on the spool.  In the case when a screw is attached to the spool, additional concerns arise.  If the spring is pulled tight on the screw,  a hump will result that will not only make the retraction difficult but will cause a fracture point and reduce life cycles. To avoid this, we recommend that the spool maintain 1-1/2 wraps of spring material at the furthest extension.  If these additional wraps are not practical in the design, another method of stopping the rotation is required. Constant Torque Spring Applications:   This type of motor spring is commonly used to retract a cable or to keep a constant torque rotational force on a spool.  It is extremely important not...

Motor brush spring and wind turbine maintenance

Čas: 2022-9-14

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...
