- 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?
- Stretch, fasten, or loosen the bolt and think of the bolt as a rubber band. It is flexible and can be stretched freely within its range of elastic deformation
- Q:Is the construction of the water supply steel pipe a telescopic device?
- After completion of the individual project, the pipe top elevation and control point coordinate shall be measured before completion of the trench backfill, and the completed measurement result sheet shall be drawn, and the completed drawing shall be drawn accordingly.
- Q:What is a bolt tensioner? How do you use it?
- The bolt tensioner is a tool for fastening and dismounting bolts. It has several forms, such as manual, electric, pneumatic, hydraulic and so onBolt tensile bolts and shear bolts, tensile bolts subjected to tensile load is axial load; shear bolts subject to shear load, tangentialThe bolt load is the force acting on the bolt, which is usually expressed by pressure, that is, the force / force acting areaThe so-called pre tightening force is a force in the mounting bolt in the bolt on the pre action (Ya Qiang), its role is to enable the bolt force and deformation, the fasteners are combined together, and can prevent the bolt fracture under impact load.Note: the preload and bolt load are less than the rated load of the bolt
- 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 are tensile and shrink wrapping?
- Shrink wrap (shrink wrap) is the use of shrink film wrapped items (or inner package), and then the film proper heating treatment, so that the film shrink and cling to the goods (or inner package) packaging technology. Shrink film is a specially stretching and cooling treatment of polyethylene film, because the film residual tensile stress in the directional contraction, the stress is heat will be eliminated, so that the horizontal and vertical were sharp contraction, while the film thickness increases, the shrinkage rate is usually 30% to 70%. The contraction force reaches the maximum value at the cooling stage, and can keep for a long time.
- 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
- Principle: the telescopic belt conveyor adds a telescopic mechanism to the ordinary belt conveyor, so that the belt conveyor can be freely extended in the length direction.
- 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.
