With the popularization of the process of automation industry, factories need more non-standard automation equipment for production, because the non-standard automation equipment mainly aims at the production of large-scale finalized products, designs reasonable automatic production line, supplemented by standardized fixtures and tools, and carries out large-scale production of all product lines in the production process.
In the face of diversified changes in the market, automatic production line production equipment has to be adjusted in time, which is the key to the wide application of non-standard automation equipment. So, in the design of non-standard automation equipment, what are the commonly used parts? Let's list them one by one.
Indicator light: generally, most of them are light-emitting diodes, with long service life, neon bubble and bulb, etc., with short service life, AC and DC working voltage.
Button and emergency stop switch: buttons are usually used for pneumatic, temporary and other control keys, and some rotary buttons are used for control; emergency stop buttons are generally red and yellow.
Fuse: mainly protection circuit, when the voltage and current is too large, it can fuse the protection circuit.
Transfer switch and power switch: control key.
Circuit breaker: it is mainly used to restore short-circuit protection. When the circuit and electrical device have instantaneous short circuit and instantaneous high current, it will trip automatically and protect the back circuit.
AC contactor: mainly used to control the main circuit of the equipment on and off, the general current is larger. Use contacts to control power on.
Intermediate relay: the same as the AC contactor is used to protect the circuit.
Thermal relay: it is a thermal element, which is mainly used for the protection of over high temperature and automatic short circuit protection of the circuit behind.
Time delay protector: generally divided into power on delay and power off delay.
Knife switch: it is mainly controlled and controlled by manual breaking. It can be divided into 2 knives and 3 knives.
Leakage switch: mainly used to protect personal safety, there are single-phase and three-phase leakage switch.
These parts are essential parts of non-standard automation equipment, the main role is to prevent accidents, protect the safety of circuit and operators.
