Explosion-Proof Electrical Equipment Fastener Requirements Solutions

Explosion-Proof Electrical Equipment Fastener Requirements Solutions

For explosion-proof equipment (explosion-proof cheerful pressure cabinet, explosion-proof analysis cabin, explosion-proof distribution box), fasteners are usually an essential part of maintaining the integrity of its explosion-proof type, especially explosion-proof type "d" and some dust explosion-proof equipment, etc. must be used for special fasteners, which play a role in fastening the explosion-proof joint surface or to maintain the sealing of the enclosure to ensure that the integrity of the explosion-proof type is critical. The integrity of the explosion-proof type is essential. If the pitch of the fasteners, tolerances, and other substandard, it is easy to fall off, lose, and other problems, thus affecting the explosion-proof performance of the equipment and the formation of safety hazards. Therefore, explosion-proof equipment should be selected to meet the requirements of the explosion-proof standard and, through the test verification of the fasteners, can only be replaced with the same fasteners. Fasteners usually include the following fastener parts.

Bolt: by the head and screw (cylinder with external threads), two parts of a class of fasteners need to cooperate with the nut, used to fasten the connection of two parts with a through hole. This form of connection is called bolt connection. For example, the nut from the bolt spins down, which can make the two parts separate, so the bolt connection is removable.

Stud: no head, only two ends of a class of fasteners with external threads. Connection, it must be screwed into one end with internally threaded holes in the parts, the other end through the parts with through holes, and then screwed on the nut, even if the two parts are tightly connected into a whole. This form of connection, called stud connection, also belongs to the detachable connection. Mainly used for one of the connected parts, thickness is large, requires a compact structure, or should not be used in bolt connection occasions due to frequent disassembly.

Screws: also by the head and screw, two parts of a class of fasteners, according to the use, can be divided into three categories: machine screws, fastening screws, and special purpose screws. Machine screws are mainly used for fastening threaded holes in the parts. A through-hole part with a fastening connection between the parts does not need to nut with (this form of connection is called a screw connection and also belongs to the removable connection; it can also be used with the nut with the two through-hole parts with a fastening connection between the parts). Fastening screws are mainly used to fix the relative position between two parts. Special-purpose screws, such as ring screws for lifting parts

Nut: with internal threaded holes, the shape is generally shown as a flat hexagonal column, there are flat square or flat cylindrical, with bolts, studs or machine screws, used to fasten the connection between the two parts, so that it becomes a whole piece.

Self-tapping screws: similar to machine screws, but the threads on the screw for the special self-tapping screws with threads. Used to fasten the connection of two thin metal components so that it becomes a whole, the components need to be made beforehand on the small hole; due to the high hardness of this screw can be screwed directly into the hole in the components, so that the formation of the response of the components of the internal threads.

Wood screws: also similar to the machine screws, but the threads on the screw for the particular wood screws with threads, can be screwed directly into the wooden components (or parts), used to a metal (or non-metallic) parts with through holes and wooden component fastening connection together. This connection also belongs to the removable connection.

Washers: a class of fasteners shaped like a flat circular ring. Placed on the bolt, screw, or nut support surface and connection between the surface of the parts play a role in increasing the contact surface area of the connected parts, reducing the pressure per unit area, and protecting the surface of the connected part is not damaged; another type of elastic washers, but also play a role in preventing the nut back to the role of loose.

Retaining ring: For installation in the machine or equipment, the shaft groove or hole groove plays a role in preventing the shaft or hole on the parts of the left and right movement.

Pins are mainly used for positioning parts left and right; some can also be used for connecting parts, fixing parts, transmitting power, or locking period fasteners.

Rivet: The head and nail rod are two parts of a class of fastenthathich that connect two parts with holes (or components) to become a whole piece. This form of connection is called rivet connection, referred to as riveting. Belong to the non-removable links. If the two parts are connected separately, the rivets on the parts are destroyed.

Components and connecting vice: a combination of parts is a combination of a class of fasteners, such as some machine screws (or bolts, self-supporting screws) and flat washers (or spring washers, lock washers) combination of supply; connecting vice refers to some special bolts, nuts, and washers a combination of supply of a class of fasteners, such as steel structure with high-strength hexagonal bolts connecting vice.

Weld nails: by the nail rod and nail head (or no nail head) composed of different types of fasteners, with welding method to other fixed connections in a part (or component) above, to connect with other parts.Explosion-proof product fasteners play an essential role; we all know that explosion-proof electrical equipment uses use of the explosion-proof shell to do with the performance of explosion-proof; if the fasteners cause problems, then the explosion-proof shell and the joint surface will not be a good match, but instead of appearing gaps or other situations, then the explosion-proof products have lost the significance of the explosion-proof. Hence, the fasteners in the explosion-proof products play an essential role.
