Fill the tank within the resistance welding of coated device design
Paint to flow along the pipe coating by the El feeding slot. Vice versa. Stop the flow. The role of valve system: by adjusting the relief valve wide E can lose control of the two side air JK maintain the appropriate values and changes in the amount of the difference is large enough to enable the system to the station almost required sensitivity. This is because when the gas detection G Detection of breath pressure head is too large. Although the G surface coating over the detection 【J, but it can not prevent detection of gas Yu-sheng, the first large flow of gas. Therefore G does not produce significant changes in pressure, the E valve does not work. Conversely,[link widoczny dla zalogowanych], when the air pressure detection El hour, G is too small pressure variation, E width is not action. Therefore, the actual situation according to the pressure to adjust the decompression week to meet the control system work properly. (2) automatic feeding system tray management and level control box when the action of the valve rj I break a relationship. 4 cylinder moon Chen et al: Resistance welding tank design of the Park, 145 * coated device surface coating bath automatic control work according to the following requirements periodically. When the paint surface than pressure testing when the first G of the test port. T every time the system sent a test signal, and each detection time tc, a few hours after the detection time t, and so repeated r. As t is 5 seconds, t is 2 seconds). If the coating liquid measured during the testing period has been lower than the pressure test port, the third delay after delay D after the valve. Generally selected for 5 seconds) to open the H VALVE, paint bucket to paint tank paint tank when the liquid level for the defense rose to more than air pressure test port after the feeding stops, the periodic detection of the fork into the state as described above , the relationship between movement time components shown in Figure 5. Automatic Feeding coating principle is: When the paint pressure tank liquid level below the mouth of detection when the detection of the first G, E two input control valve air pressure difference between the larger end, the E cut-off valve, so that input A valve control terminal pressure. After a period of time after the B valve conduction delay, and to input control terminal c Kang pressure. After a certain delay and then by conduction c valve, which cross the D end and the valve control input pressure, and finally through the D valve after tD conduction delay. H so that the pneumatic valve to open, the paint storage tank in the shed along the pipeline under pressure paint tank. When the paint surface was achieved, a pressure test port, the E of the two input control valve air pressure is basically the same side, leaving E valve is turned on. A valve closing, B, C, D are cut-off valve, pneumatic valve H off, no material flow of people paint tank. The process is repeated to achieve the purpose of automatic control of liquid coating to ensure the coating system work properly.
