The lock is the most important protection element in the vault door . Many unscrupulous elements enter the vault door through breaking the lock. Therefore, the quality of the lock is very important. Today, we mainly explain the basic parameters and the matching method of the lock. . Please click {Contact Us} for the detailed parameters and pricing of the vault door
First of all, let's first look at the locks that are applied to the vault door. The common ones are: mechanical locks, fingerprint locks, electronic locks, palm print locks, iris meters, double locks, etc. Next, we will unlock the locks again. Collocation and core technologies.
Vault door locks with a common way:
most common:
The most common is nothing but two mechanical locks, with a double-headed lock, this combination is very practical, so whether it is a blackout, or there are some power failures do not need to worry, but it also has the effect of three-lock linkage, If you set it up, you only need to open two of the locks. In this case, if one of the locks fails or if one of the managers forgets to bring the key, it can be solved.
Advanced:
The nothing more advanced is that the iris instrument is equipped with palmprint locks. Both of these locks are expensive, very high-end, very easy to use, and very unique. It is almost impossible to have the same person and your palm in the world. Like the iris, although it is the same, it has a relatively high requirement for the environment, and it is also very strict with electricity. Of course, if you have these locks, I believe everyone will handle these things well.
the safest:
Two mechanical locks with palm print lock or iris meter, and achieve the effect of three-lock linkage, this setting is extremely safe, such a combination of both environmental and electrical requirements must be more than the above peace, but it The protective effect is also very good, because it is not only unique, but also less likely to be destroyed.
Jinkumen three-lock linkage technology introduction:
The three-lock linkage that has been popular in the past two years also uses three kinds of locks, and then to achieve three-lock linkage, then what is the principle of three-lock linkage? To complete the lock open state, three of them need to be fully opened, and the vault door code can be unlocked. One can not operate. This design is specially developed for the failure of one of the passwords in the emergency or other reasons that led to a password failure.
Three-lock linkage seems simple, but it is very practical, because in the process of use, we can not guarantee the normal use of each of these locks, and if there is a big forget to bring a key or forget password, there is no harm, so this This type of lock collocation has quickly been favored by consumers. Most of the vault doors nowadays are equipped with three-bar linkage.
PTA Powder
Main application:Repair and
strengthen workpiece surface, significantly
Welding method:PTA welding
Main equipment:PTA welding
machine
Flame core temperature: about 10000℃
Technological characteristics:PTA has high
temperature, concentrated energy, stable combustion, small heat affected zone,
fast welding speed, high production efficiency, easy to obtain low dilution
rate of surfacing layer, surfacing layer and workpiece matrix are metallurgical
bonding,, bonding strength is high.
PTA welding technology is one of surface
strengthening methods, which has high deposition rate, low dilution rate, and
could be applied with many kinds of powder. The manufacturing craft of PTA
powder is normally gas atomization, which reduces satellite of powder. We
supply 4 main categories of PTA powder: Nickel-based alloy powder, Iron-based
alloy powder, Cobalt-based alloy powder and Mixed Powder.
Nickel Based Alloy Powder possesses high
temperature resistance and wear resistance, it is the most popular alloy powder
applied by PTA welding both domestically and internationally. Coating hardness
is within the range of HRC 30-60. It could be applied to various industries
like agriculture, plastic, paper, marine and steel making where wear and
corrosion protection needed. Some examples are plunger, moulds, pump leaf and
screw.
Iron Based Alloy Powder is more widely used
and a more economic choice. With high abrasive resistance, it is more commonly
applied to mining tools, drilling tools and mixers of iron and steel making
industry, coal industry, shaft, oil and energy industry.
Cobalt Based Alloy Powder is recommended
for corrosion and oxidation resistance, with better hot hardness values than
equivalent Nickel based alloy powder. It is widely applied to steel making
industry, coal industry and mining industry.
Mixed powder mainly refers to NiCrBSi
mixing with other hard-phase powder such as cast tungsten carbide and other cemented
alloy powder, which allows the powder better hardness around HRC60 and
excellent abrasion resistance.
Mixed powder is more often used for mining
equipment for oil sands, lignite, oil drilling tools, excavator buckets,
extrusion screws for plastic processing, grain and oil processing, etc.
