Hefei Secco 3 teach you to buy security doors

With the vigorous development of the commercial era, the selection and installation of metal detection doors not only need to consider the use of functions, but also need to pay more attention to the appearance of doors, the convenience and service life of people entering and exiting, and so on. Metal detection doors (also known as: security doors) can be roughly divided into: rain-proof security doors, economical security doors, portable security doors, metal security doors, copper security doors and several categories.

In order to prevent consumers from buying low-quality security doors, Hefei Secco shares three tricks to quickly purchase high-grade metal metal detection gates:

A look: see if the metal detection door shows signs of fading, whether the exterior is beautiful, and whether the power is normal.

The second hearing: listen to the metal detection door is a chaotic alarm or a normal alarm, the normal alarm can be initially considered that it is in line with the requirements.

Three tests: The installed metal detector door is flexible, easy to use, and easy for the staff to learn.

Pneumatic cylinders (sometimes known as air cylinders) are mechanical devices which use the power of compressed gas to produce a force in a reciprocating linear motion.

Like hydraulic cylinders, something forces a piston to move in the desired direction. The piston is a disc or cylinder, and the piston rod transfers the force it develops to the object to be moved. Engineers sometimes prefer to use pneumatics because they are quieter, cleaner, and do not require large amounts of space for fluid storage.

Because the operating fluid is a gas, leakage from a Pneumatic Cylinder will not drip out and contaminate the surroundings, making pneumatics more desirable where cleanliness is a requirement. For example, in the mechanical puppets of the Disney Tiki Room, pneumatics are used to prevent fluid from dripping onto people below the puppets.

Once actuated, compressed air enters into the tube at one end of the piston and, hence, imparts force on the piston. Consequently, the piston becomes displaced (moved) by the compressed air expanding in an attempt to reach atmospheric pressure.

Although pneumatic cylinders will vary in appearance, size and function, they generally fall into one of the specific categories shown below. However there are also numerous other types of pneumatic cylinder available, many of which are designed to fulfill specific and specialized functions.
