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: Is the construction of the water supply steel pipe a telescopic device?: The trench excavation method should be carried out before the investigation and study, fully understand the channel section of the soil, underground water, underground structures, underground trench near building and construction environment, find the problem timely contact with the construction unit, research on treatment measures. In order to prevent over excavation, the groove should be laid out before excavation, and the excavated layer shall be excavated at intervals according to the opening slope, and the excavation depth shall be measured at any time.

Q: What is a limiter?: To understand what a limiter is, you should first know what a telescoping device is The expansion device is also called expansion joint, expansion joint, compensator and expansion joint. Expansion device capable of axial expansion in a certain range, the offset can overcome different axial pipe butt within a certain angle and produce, installation and convenient disassembly pipeline valve greatly, in the pipeline to allow expansion in free expansion, once over its largest expansion amount rise to limit, to ensure the safe operation of pipeline the

Q: How to achieve telescopic power arm: Consider synchronous motor, screw drive, photoelectric induction limit, PLC connection drive control displacement

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: 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 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 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?: When the intermediate slider is moved upwards, the switch is moved upward to prevent the spring 2 from compressing the spring at the lower dead point position and the elasticity does not reach the maximum value. Only when the switch force is slightly greater than the maximum value of spring 2 elasticity, the convex switch is retracted, and the middle slider begins to move up.B. when the middle slider moves down, the upper half of the convex switch is smaller, so that the spring 1 has sufficient elasticity to make the middle slide switch locked by the convex point switch. And 2, 3 is not enough to cause the umbrella middle slider has been declining.

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!
