Q:What is a limiter?
Mainly for the protection of the safe operation of the pipeline, has the following functions: compensating absorption pipeline axial and transverse and angular deformation; absorption equipment vibration, reduce the vibration on the impact of pipeline equipment; deformation of the pipeline, absorb seismic subsidence. The utility model relates to a limit extension device, in order to improve the service life of the telescopic device, and a position limiting device is added at both ends of the expansion device. During stretching, the expander is damaged in order to avoid excessive stretching. A device for limiting tension is added at both ends of the expansion device. So it's called limit extension device. 1, the expansion device should check its type, specification and piping configuration before installation, must comply with the design requirements.
Q:What are the main uses of a bolt tensioner?
But the general does not hurt the threaded bolt tensioner, high precision, high tensile bolt General requirements is the most appropriate, domestic stretcher good brand, I recommend Prima, quality customer service is good, and I hope to help you!
Q:How do you pull the contracted muscles with a mechanical device?
A muscular spasm is a controlled contraction that causes the muscles to be tense and rigid, usually caused by lactic acid accumulation. 1) massage the muscles. 2) gently pull the muscles. Namely: 1 spasms can occur in any muscle, usually caused by unaccustomed activity, often occurring in the calf muscles of the gastrocnemius. When you massage, the injured must sit or lie down. 2 gently pull the muscles to counteract the spasms, and pull the foot to the shin in this case. Massaging and pulling muscles can increase the flow of blood in the muscle to take away and disperse the local lactate. Muscle spasm first aid Beijing Morning Post muscle spasm is commonly known as cramping. It is an involuntary tonic contraction produced by the muscles.
Q:What are the main uses of a bolt tensioner?
Stretch, fasten, or loosen the bolts and think of the bolts as a rubber band,
Q:The working principle of the bolt tensioner
Bolt hydraulic stretcher or bolt tension, it uses hydraulic booster pump (ultra high pressure hydraulic pump) source, according to the tensile strength, yield tensile and elongation coefficient determined, using ultra high pressure pump the stretch, the bolt is applied force in the elastic deformation zone is stretched, the diameter of the bolt a slight deformation, so that the nut is easy to loose, and it can be used as a hydraulic interference connection device of applied axial force, top pressure installation. The biggest advantages of stretcher can make a plurality of bolts and fixed value fastening and disassembly, uniform force distribution, is a safe, efficient and fast tool is the best way to bolt fastening and disassembly of various specifications. Used in petrochemical, nuclear power, wind power, hydropower, thermal power, ships, railways, aerospace, mining, heavy machinery and other fields. According to different working conditions, application conditions and user requirements, it can be used as a special stretcher design.
Q:What kind of materials are used in the telescopic equipment of machinery industry?
Mechanical transmission is widely used in mechanical engineering, mainly refers to the transmission of power and motion by mechanical means.The frictional transmission that transmits power and motion by the force of friction between the parts, including belt drive, rope drive, and friction wheel drive. The friction transmission is easy to realize stepless speed, transmission shaft mostly can adapt to large distance, overload sliding can also play a buffer and protection function of the transmission mechanism, but the transmission cannot be used for high power applications, can not guarantee the transmission ratio accurate.The meshing transmission of power or motion by means of the meshing of an active component and a follower or by means of a middleware, including gear drive, chain drive, screw drive and harmonic drive.
Q:What are tensile and shrink wrapping?
Stretch packaging began in 1970s as a new packaging technology developed from shrink packaging. Stretch packaging is a packaging method that relies on a mechanical device to wrap the elastic film around the package at room temperature and seal it at the end thereof. Since stretching packaging does not require heating, the energy consumed only shrinks by 1/20 of the package. Stretch wrap can bale single items, can also be used for packing pallet packaging, set.
Q:How to achieve telescopic power arm
Consider synchronous motor, screw drive, photoelectric induction limit, PLC connection drive control displacement
Q:Mechanical principle of belt expansion machine
Conveyor sections: two, three, four. Width of conveyor belt: 500, 600, 700, 800, 1000, 1200mm. Belt conveyor speed can be selected: constant or variable speed. Belt conveyor direction can be selected: one-way or two-way conveying materials. Belt conveyor angle can be selected: horizontal, fixed angle or automatic lifting. The fixed section of the conveyor can be fixed or fixed. Conveying speed: <30 M / min.. Conveyor capacity: <70 kg / m..
Q:What is the automatic telescopic function of an automatic umbrella?
The most important thing about the design of a fully automatic long handled umbrella is the choice of the elastic potential energy device between the upper and lower springs. The traditional semi automatic long handle umbrella pushes the slide block upwards through the pretightening force between the springs between the two sliders so as to realize the opening of the long handle umbrella. Therefore, it is proved by experiments that if a spring is added to the slider, and whether the slider can move downward similarly, the experiment shows that the umbrella can be closed. Then, the following work is how to determine the size difference and working state of the two spring preload.
