Q:The working principle of the bolt tensioner: During operation, the high-pressure oil output by the power source is conveyed to the piston cylinder 3 by a high-pressure hose, and the piston in the piston cylinder moves upward under the action of pressure to drive the stretching nut upwards. The nut and bolt tensile work thread, thereby stretching the working bolt, the bolt elongation reached the required amount of deformation, deformation control in the elastic deformation range, then the pre tightening or disassembling operation, finally through the hydraulic or mechanical return the work bolt return to its original shape, finish the homework.

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: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 limiter?: The compensator of the inner sleeve shall be noted that the direction of the inner sleeve is consistent with the direction of the medium flow, and the hinge rotation plane of the hinge type compensator shall be in accordance with the displacement rotation plane.

Q:What is a bolt tensioner? How do you use it?: Pretension is a familiar term in machinery, architecture and other fields. General general description: in the connection (connection mode and use is various, before the work load is), in order to enhance the reliability of the connection and close, to prevent the load by connecting cracks or slip and pre applied force between.

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 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.

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!

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: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.
