Surface plating process electroplating process for making metal products and plastic products for plating and electroplating process in the disposal of the phosphate, degreasing, roughening, nickel, copper base, copper and so the focus needs a certain temperature, all demand energy-saving heating
Heating energy-saving equipment, such as electroplating factory method on treatment of the following two:
Section 1. Direct heating:
Features: Made of stainless steel, titanium, Teflon and other heat exchanger direct heating bath, automatic temperature control, no temperature difference, the average temperature.
Partial disposal of high temperature heating before plating saving about 50 percent,
After the disposal of plating nickel, copper base heat energy and other savings of about 70%.
Suitable for gantry line, ring lines, large bath plating factory
Section 2. Indirect heating method:
Characteristics: After heating heat pump host of hot water storage tank, and then from the hot water tank is placed through serpentine titanium tube heating bath,
By the temperature controller controls the water solenoid switch to control the temperature, there is the temperature difference, the central heating.
Saving about 50%.
For manual line, continuous plating lines, bath is small, energy-saving heating tank plating more electroplating factory.
Indirect heat treatment program analysis
Operating logic:
Electroplating heating energy saving heat pump unit for hot water storage tank of water heated to 70 ℃, the hot water tank through serpentine titanium tubes for heating bath, means a temperature control box on each heating tank, through tube temperature controller way solenoid valve switches and automatic timer switch.
When the temperature is below the set temperature, the solenoid valve opens. When the temperature is higher than the set temperature, the solenoid valve is closed.
Since the demand for hot water circulation pump stop working, and when the solenoid valve is heated tank all closed, or partially closed when a large, pressure increased in the process, the main water on the road need means of pressure to ease bypass line .
