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: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: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?

Ensure the load is required in the standard setting, screwing length of screw thread is also provided; ensure the load refers to the mechanical test project of bolts and nuts, the threaded part is load bearing ability (because the threaded portion of the most vulnerable).

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: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?

Stretching: one of the basic characteristics. The tensile feature is to draw the cross section of the drawn cross section in a specified tensile direction at a specified depth. Stretching is the most commonly used entity creation type that is suitable for creating rule entities and should be skilled.The main purpose: contraction of envelope: complex parts or components 1. can be used as a reference or package model to create a lightweight version; 2. can be used to create geometric model sharing relationship with suppliers and customers, and get rid of what you don't want to share details; file - save a copy - type contraction envelope; create components, in the form of a activation element inserts - shared data - shrinkwrap -- referring to the type for the components of a subset of context.

Q:Mechanical structure and principle of automatic focusing lens for camera

The principle of the infrared ranging method is that the camera takes the initiative to emit infrared light as the distance measuring light source and the geometric relation between the infrared LED, and then calculates 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?

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.
