Trends and characteristics of coating equipment along with the rapid development of science and technology forward spraying equipment types, new technologies, new materials, new techniques are emerging. Performance in the development of electronic technology, CNC technology, laser technology, microwave technology, and high-voltage electrostatic technology to painting equipment automation, flexible, intelligent and integrated brought new vigor to make ever-increasing variety of machine tools, technical level continuously improve the spraying equipment, but also the people's aesthetic vision gradually improved. Its trends towards: (1) coating equipment to improve the comprehensive utilization of waste reduction coatings, coating technology to make more environmentally friendly and green vision. (2) will become more of CNC automation, efficiency multiplied so easy to operate. (3) assembly-line mode to continue to spread. (4) high-tech applications. (5) the development of flexible, integrated coating production systems. (6) Security pollution coating production systems. Within a common fault detection method to check the electrical solenoid valve powder coating equipment, gas loop connecting element analysis of automatic painting machine equipment if the above three steps have not found any problems, check all circuit. Check whether the circuit breaker wire, especially if the wires inside the trough is due to pull trough cut off. Check whether there is damage to the trachea of ??creases or cracks. If severe tracheal creases or cracks, replace immediately.
