Q:What is the automatic telescopic function of an automatic umbrella?
Working process and principle analysisA. the long handled umbrella is in a tight position, that is, the middle slide is at the lower dead point1. the elasticity of the spring 1 at the moment reaches its minimum value and is greater than 0.The 2. middle slider is at the lower dead center and is locked by the bump switch 1.On the 3 of the 3. rib buckle at the fulcrum of the slider 2, a spring 2 stretch for 0.The B. long handle umbrella is at the beginning of the opening, i.e., the middle slider begins to move up
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: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: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: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 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
Pneumatic, cylinder. There is an electromagnetic valve, an air compressor.
Q:What is a bolt tensioner? How do you use it?
Bolt tensioner is a bolt hydraulic stretcher with hydraulic booster pump (super high pressure hydraulic pump hydraulic source) provided, 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, bolt the diameter of 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: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: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..
