- Q:What kind of materials are used in the telescopic equipment of machinery industry?
- The most common form of bond failure is shear. So the key requires enough strength and steel. No. 45 is the most commonly used steel.
- 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: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 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: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: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:Mechanical structure and principle of automatic focusing lens for camera
- From the basic principle, AF can be divided into two categories: one is based on the camera and photographed location AF target distance between measurement and another is based on the focus screen clear focus imaging detection.
- 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: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: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.
