A distiller is an electric heating device used to prepare distilled water. In the process of using the distiller, the cold water for burning the distilled water is required to meet the needs and cannot be interrupted. Otherwise, the heater will be damaged due to dry burning. Therefore, installing a set of water cut off automatic protection device to the distiller can ensure the safe operation of the distiller under sudden water cut.
After the whole device is installed, open the valve of the water supply pipe, and the water enters the cylinder body from the upper inlet of the right cylinder body. After decompression of the right cylinder, water enters the left cylinder from the lower communicating tube. Part of the water enters the distiller through the lower nozzle. The other part of the water lifts the float in the cylinder under the action of buoyancy. At the same time, the iron flag on the pull cord left the proximity switch and moved to the left end of the bracket. When the iron flag leaves the proximity switch, the contact point of the proximity switch actuates the contact point of the main circuit and sends power to the distiller to begin work. When the water supply line interrupts the water, the water in the left cylinder gradually decreases, causing the float to fall to the bottom of the cylinder. At the same time, the iron flag is pulled back to the right end, giving a signal to the proximity switch to make the contact point of the main loop of the control circuit act, cut off the power supply of the distiller, and the distiller stops working, which plays a role of water cut control and protection.
The distiller device achieves the intended purpose through installation and commissioning, and realizes automatic control and protection of the entire process. Sensitive action, reliable performance, economical and practical; to achieve a continuous water preparation, improve the efficiency of the distiller, save energy; TWK220) A10JK type proximity switch selection should be based on the main circuit load and control circuit load size selection. In this example, a 6 kW distiller is used. The proximity switch of this type is selected to be slightly larger. It should be re-selected according to the regulations. Note that according to the quality of water, the surface of the retort tube and the surface of the heater tube should be periodically cleaned at an appropriate time. , In order to avoid affecting the heat transfer efficiency, burn out the heating element; the gap between the proximity switch and the iron flag should be adjusted properly, too large or too small will affect the sensitivity of its movement. After testing, when selecting TWK220) A10JK type proximity switch, the clearance should be less than 8mm.
