Electroplating equipment Introduction of auxiliary device rectifier
Compared with other industrial technologies, the equipment of electroplating equipment is not only simple, but also has great flexibility. Taking power supply as an example, as long as it is a device that can provide DC power, it can be used as the power supply of electroplating equipment. From batteries to AC/DC generators, from selenium stacks to silicon rectifiers, from silicon controlled rectifier to pulse power supply, etc., they are all available power supplies for electroplating. The power can be determined by the surface area of the product to be plated, or the number of products that can be plated in each slot can be determined by the existing power supply.
Of course, the formal electroplating equipment processing will use a more reliable silicon rectifier, and the main indicators are the size and adjustable range of the current value, and the voltage will change from 0 to 15V with the current change. According to the power, single-phase or three-phase input can be selected, which should be able to prevent moisture and heat dissipation. The industrial electroplating power supply generally ranges from 100A to thousands of amperes, which is usually designed and determined in advance according to the needs of production capacity. It is better to use a single tank instead of one power supply to supply power to multiple tanks. If the test is only conducted in the laboratory, a small experimental rectifier power supply of 5~1OA will be used.
In 1993, the Ministry of Machinery Industry of China organized experts to prepare the standard of rectifier equipment for electroplating (JB/T1504-1993), which stipulates the model, specification and technical parameters of the electroplating rectifier designed and produced in China. With the progress of electric power science and technology, there has been great improvement in the design and manufacture of rectifier power supply in recent years. Many electroplating power supplies have developed towards multi-function, high-power, small size and other directions. Periodic commutation, adjustable pulse and smooth adjustment are common functions.
