- Q:Is the construction of the water supply steel pipe a telescopic device?
- The pipe line survey shall be carried out in accordance with the coordinates of the pipe line control points. In order to master the control points of the canal well, the permanent reference piles shall be introduced and set up in the engineering site, and properly maintained, and the project shall be submitted to the owner after completion of the project. After the above work, please check the line of supervision personnel, confirm the ditch excavation work.
- 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?
- He is elastic, in his range of elasticity can be stretched, and generally 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 you help!
- 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?
- 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 structure and principle of automatic focusing lens for camera
- Ultrasonic ranging method, which is based on the ultrasonic wave in the digital camera and the time between the subject of distance measurement. Digital cameras are equipped with ultrasonic transmitting and receiving device, when the ultrasonic vibration generator for ultrasonic, ultrasonic to the subject, is the receiver's perception of return immediately, and then by the integrated circuit according to the ultrasonic round-trip time to calculate the focusing distance.
- 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.
