5. Pneumatic dewaxing system:.
The inflation system consists of a solenoid valve, fine adjustment valve, pipeline, barometer, etc. When the inflation pressure reaches the upper set value, inflation automatically stops. If the pressure is below the set lower value, gas can be supplied automatically. When the pressure reaches the set value, the gas release valve opens automatically. The decoking gas enters the outlet chamber of the vacuum pump through a pipeline through the decoking tank.
6. Electrical control system.
The control cabinet is a standard electrical control cabinet structure, integrated ventilation system, which can ensure the normal use of components and tools in the cabinet without being affected by high ambient temperature. There is a sound and light alarm above the cabinet. The electrical control system is concentrated in the control cabinet, which uses touch screen and PLC communication control. Process setting and daily operation can be completed using the touch screen. The control section is equipped with air switches, push buttons, contactors, relays, indicator lights and other components to achieve logical control of external equipment through signals from various sensors. The overall operation of the equipment can be displayed in real time on the LCD display, the operating status of all operations is equipped with safety lock protection, overheating without power or maintenance, water and electricity (delayed stop of heating, vacuum pumps, etc.), air pressure protection etc.
The operating system interface allows you to obtain various operating instructions and process status, and the design of the system monitoring screen, troubleshooting screen and help interface, the system can be viewed at any time, recording various data during operation. The red flashing indicator on the panel is used to display various alarm functions. The operator can determine the alarm position according to the prompts and take action immediately. The temperature control part consists of a temperature control table, armored single-core k-type thermocouple, infrared thermometer and silicon voltage regulator. k Temperature control is adopted for low temperature heating section within 900℃, and it switches to infrared temperature measurement after it reaches 900℃, while the thermocouple is transmitted to the outside through the heating cylinder. Ensure long and efficient thermocouple life. The heating power is provided by a thyristor power regulator. Feature 1: With the advantages of soft start and soft shutdown, it can protect the power supply and reduce the impact on the load. Feature 2: Wide voltage regulation range, constant current function, over-current and over-temperature protection.
7. Water cooling system.
The cooling part includes furnace body, furnace door, vacuum device and water-cooled copper electrode. The pipes and valves are made from 304 materials and are labeled. The inlet pipe is equipped with a contact pressure gauge, and the return pipe is equipped with a flow range. If the water pressure is below the set value of 0.15 MPa, a sound and light alarm is activated and heating stops. The cooling water system is equipped with an emergency bypass water supply interface and a tap water interface with a manual ball valve. When the equipment does not have normal power, open the tap water emergency valve to ensure the equipment is naturally cooled, the cooling water is supplied by circulating water in the closed cooling tower. The cooling tower can supply water automatically, saving water, safe and reliable.
8. Pneumatic system.
Includes pneumatic triplex, solenoid reversing valve, cylinder and nylon hose, which can provide clean compressed air.
