In the constructor combining good design usually recommend a combination of nuts and bolts using the occasion of merger or a combination of excessive force too much pressure load fault should be broken bolt threads should not be torn. The same concept as the assembly of self-tapping screws. Especially in the case of the stress load. If the merger fails, it should be, instead of thread damage or breakage.
Resistance to thread damage, pull out the function of the shear strength and thread area in other words, the Ministry of screw size, thread length role, thread depth control, thread length equal to the combined effect of overlapping thickness of the workpiece. Theme overlap depth hole diameter from the preparatory decision, another determining factor - screw sizing torque and tensile strength.automatic load sensing power switch
Thickness in any combination, to increase the size of the screw to increase the tensile stress load region, the thread shear stress ratio of the load area, often resulting in tearing or pulling thread, such as reducing the size of the reduction ratio of the screw, but will increase the tightening torque cause screw is broken, so how to balance the tensile strength to resist tearing or pulling the thread size depends on the thickness of the workpiece and use decisions.power load unbalance

Copper nut Introduction
As its name implies, is defined as the use of copper material (usually lead, brass, such as H59, H61) produced in our daily exposure to copper nuts are mainly hexagonal nut or nuts and bolts to match other brass nut brass nut .how to calculate power load
So why in the daily production activities, using it to brass nut? Since copper nut with rust, corrosion, thermal and electrical conductivity and easy strong advantages, generally used for rust, temperature, electrical conductivity, thermal conductivity, such as the use of the environment, such as faucets, valves, electrical switches.
Another major objective of copper nut injection molding, heating, or directly into the injection molding described above, the brass has good thermal conductivity, for example, by embedding a heated copper nut, the nut can quickly become hot copper accelerated the efficiency, On the other hand, the heating can quickly transfer heat brass nut plastic parts, so that the soft plastic around the hole, which will help push into the hole; ah, if the injection effect will be if he do it? As we all know, the PA / NY LOY / PET melting point higher than 200 ° C, copper melts quickly turned into a plastic nut after high temperature, injection molding, plastic body rapidly cooled crystal hardening, if the temperature remains at a high temperature copper nuts, The result will be what? Clever you must have guessed, the result is brass nut and plastic parts loose or contact your local development cracks. Therefore, the use of injection molding brass nut steel nuts.
Application of the injection molding metal nut shape is circular in shape with the general pattern of the imprint mold is generally cylindrical melt, hot or cold formed into the copper coil or with a certain slope with barbed shape.point of load power supply

1, drilling depth: the relevant information on the length of the Remington Power loads tube, but I found in the specific construction of this deep enough, may be to the hole debris residues, so you re better off than the expansion pip e length deep about 5 mm. As long as you is greater than or equal to the length of the expansion pipe, then left in the ground expansion bolt length equal to or less than the length of the expansion pipe.

2 is correctly installed in the concrete after a M6/8/10/12 Remington power loads, it is best not ideal maximum static force 120/170/320/510 kg. (Note, vibration causes the bolt loose) 3, the expansion bolts requirement on the ground of course is the harder the better, it also depends on the objects you need to fixed the force.

Fence concrete drop in anchors, also known as S-Concrete drop in anchors, the fence has been widely used features of this anti-theft screws:
1, easy to use.
2, anti-theft effect, fence concrete drop in anchors only the posit ive direction of the force point in the opposite direction force point, once installed, it can not be removed.

3, beautiful appearance.
4, is not removable.
: In the market also appeared eccentric hole anti-theft screw this up a fence anti-theft screws may not remove the mounting features.
Fence anti-theft screws M6 series main specifications can be divided into: M6 * 20, M6 * 25, M6 * 32, M6 * 35, M6 * 40 the M6 ​​* 45,6 M * 50, M6 * 55, M6 * 60, M6 * 70, M6 * 80, M6 * 90.
Applications:
Guardrail anti-theft screw nut in the application and screw nut is not restricted, its wide range of applications, such as: power facilities, rail facilities, highway facilities, oil facilities, urban lighting street lighting facilities, light car tires and utilities fitness equipment and so on. As long as the items, fixed with a screw nut to prevent unintended removal can be applied to this technology and products to prevent theft and lost, thereby strengthening the management and protection of public facilities and equipment. Superior product performance, widesprea d attention and praise by the various sectors of society.

Pneumatic conveying dust works well, is easy to realize mechanization, automation, reduce labor intensity, save manpower. Its disadvantage is that the power consumption; wear of equipment and piping, design, construction or improper operation, capacityMoSi2 heating element

Could easily lead to material deposition, resulting in blockage interrupt conveyor; should not be transported humidity, sticky, fragile materials. In the conveying process, can be performed a variety of process operation, such as mixing, pulverizing, separation, drying, cooling, and can be

To prevent the material damp, contaminated or mixed with debris, thus casting, metallurgy, chemical industry, building materials, food processing and other departments have been applied. Pneumatic conveying applications, more than 100 years of history, but as a dust-proof technical measures,grain handling equipment

The workshop inside and outside used to transport sand, coal, metal powder, fertilizer, cement, grain, cotton, tobacco powder, granular and fibrous materials, or things of the last few decades. At present, China has s ome of the rubber plant use with pneumatic conveyingcrude oil refinery

Stainless steel hose clamp installer: Assembly in the welding board assembly before, in order to better determine the direction of the clip, it is recommended that the first fixed at marked after welding on welding, embedded on the tube clip the lower half of the body, put required a fixed tube. And put on the other half hose clamp body and cover with screws tightened. Should not be soldered directly mounted the good pipe clamp base plate. Installed ground rail, rail welding based on, or attached with screws, followed by rail nut pushed orbit and turn 90 degrees to the lower half of the pipe clamp body embedded nut, put the tube to be fixed, and put folder on the half pipe on the body and cover with screws. Stacked assembly, the rails can be welded to the foundation, or screws first installed the upper and lower half pipe clamp body, put the required fixed tube sprinkle on half pipe clamp body, fixed with screws, locking cover to prevent it from rotating. Folder and then install the second pipe, as above. The elbow assembly, the assembly bends should be directly in front and rear portions of the elbow with Insein pipe folder fixed.
