Product introduction: The electrode rod is inserted under the water surface of the electrode tank, and the power is turned on. The water is heated to boiling by the ion movement in the water. The amount of water vapor (humidity) generated is taken from the water level in the electrode tank, that is, the electrode. The depth or area of the rod inserted into the water, the steam spray rods are evenly distributed in the air-conditioning box or the air duct, and the air is absorbed to achieve the purpose of humidification. Electrode humidifier structure: Generally, the conductivity of tap water is between 125 and 1250 μ s / cm, which contains trace conductive ions (such as calcium, magnesium ions, etc.), and water is a conductive liquid. When tap water enters the electrode humidification tank, the water level gradually rises, until the water level passes through the electrodes in the humidification tank, the electrodes will form a current loop through the water, and the water will be heated to boiling to produce clean steam. The electrode humidifier controls the output of steam by controlling the level of water in the humidification tank and the conductivity. Technical parameters: Standard configuration: 1.JDJ-X (whole machine) Standard configuration humidifier host: (box, humidifier tank, inlet and drain solenoid valves, bottom bracket, control board), steam hose (1 meter), steam Distribution pipe, condensate pipe (1 meter). Input method: humidity input / external control input, fan linkage input; AC220 ± 20% power supply. Output method: humidification / water supply / drainage / alarm; DC24V / 50MA user humidity sensor professional power supply. Optional accessories: humidity controller RS485 communication Interface 2. Length of steam distribution tube 3. Three control methods a. Switch-type control: it can be turned on (closed) when it receives a signal, and it cannot be turned off (on) without a signal, and the precise control of humidity cannot be achieved, and the general control accuracy is within ± 5% RH . b. The time proportional control adopts fuzzy rules for PID adjustment according to the actual working conditions. It automatically adjusts the parameters and cooperates with the solid state relay (SSR) to adjust the power to achieve the best energy-saving state of maintaining humidity. The accuracy can reach ± 3% RH. c. Linear proportional control: Use the intelligent control module (SCR) to cut the output power of the phase angle, and output the control signal accurately by the controller, so that the power output corresponds to the control signal linearly, and the accuracy depends on the selected sensor. Each of the above control forms uses PID + fuzzy control algorithm, which has higher control accuracy. 4. Connection of the condensate pipe of the spray bar Use a hose clamp to reliably connect one end of the heat-resistant hose with an inner diameter of Φ10mm to the condensate pipe on the steam spray bar, and the other end is naturally introduced into the nearby floor drain. Note: This hose must not have any installation defects such as dead bends, twists, etc. that affect the smooth flow of condensate. The working process of the electrode humidifier: 1. When the steam needs to be humidified, the main power contactor provides voltage to the electrode rod, the main control board opens the water inlet solenoid valve, and the water enters the electrode tank through the water injection cup and water injection hose from the bottom; when When the electrode rod is in contact with water, an electric current is generated, which eventually heats and converts the water into steam. The more the electrode rod is in contact with water, the greater the current generated and the more heat. When the required amount of steam is reached, the water inlet solenoid valve is closed. Due to the water level falling due to evaporation or drainage, the water inlet solenoid valve will open to replenish the water until the required amount of steam is reached. If the required amount of humidification is reduced, the water inlet solenoid valve will be closed immediately (even if it was open at the time), and the water discharge solenoid valve will be opened until the required amount of steam is reached. 2. Control the microprocessor on the main control board, by detecting the heating current, make the water inlet and drain solenoid valves act, and continuously control the steam output. 3. Water level control When the high water level sensor in the humidification tank detects the water level, the water inlet solenoid valve is closed immediately. 4.Draining system Due to the evaporation process, the minerals in the water will increase and the conductivity of the water will increase. If the minerals continue to increase, the heating current will increase. If the minerals exceed a certain level, the humidifier will work abnormally. , The water in the humidification tank needs to be replaced. At this time, the water inlet solenoid valve and the water discharge solenoid valve are opened at the same time. After a predetermined drainage time, the water discharge solenoid valve is closed, and the water inlet solenoid valve continues to work until the water in the humidification tank reaches High water level. Features of electrode humidifier: 1. Multiple control signal modes. Equipped with voltage control (0-10V / 0-5V), current control (4-20MA), on-off and switch control (can be set by buttons according to site requirements). 2. Automatically adjust the amount of humidification according to the size of the signal (external control) or output the corresponding amount of humidification (local control) according to the set working mode according to the humidity difference between the detected humidity of the environment and the set humidity. 3． Automatically fill, replenish and automatically adjust the appropriate water level. Automatically add water when the machine is turned on, and automatically replenish water when working, and automatically adjust the appropriate working water level in the humidification tank according to the water quality, water temperature, and upper and lower water flow. 4． Automatic cleaning. The control board automatically adjusts the cleaning times and cleaning time according to the water quality and current change rate. 5. Limit water level limit function. Due to water quality, electrode scale and other reasons, the current detection is invalidated. The water level in the humidification tank rises to the limit and contacts the limit water level electrode. The control board automatically closes the water inlet valve automatically. 6. Large and small current and abnormal fault protection function. ① The humidification current does not reach the rated value within a certain time due to scale and other reasons. ② The current exceeds the limit value due to water quality and other abnormal reasons. ③ The humidification control board fails due to other abnormal reasons. In any of the above three cases, the control board will automatically stop working and output a passive signal. 7. Remote monitoring of fault signal, working status of prefabricated humidifier on control board and fault alarm output signal indication. Indicate humidification working status; output high and small current alarm signals, manual reset and drainage operation can be connected to external equipment chain, humidification synchronous operation. 8. Equipped with RS485 interface, which can be connected to the computer to monitor the related status (optional component). 9. Control board with parameters (humidity, required humidification amount, switch) display, working current display. 10. The control board is equipped with four keys, which are convenient for users to set different levels of user parameters.

Installation of water inlet and drain pipe 2.1 Installation of water inlet pipe When installing the water inlet pipe, ensure that the water inlet hose and the water inlet solenoid valve interface of the humidifier are tightened to prevent water leakage, and the water inlet hose is naturally bent to ensure The water inlet is unobstructed; 2.2 Install the drainage pipe. Because there is no pressure for drainage, it is recommended to use a Φ22 * 1 hose. One end is reliably connected with a hose clamp and the outlet of the humidifier drain solenoid valve, and the other end is led to the nearest drainage floor drain. 3. The installation of the steam boom is drilled at a certain position according to the actual outer diameter of the boom, the boom is inserted, and it is reliably fixed with bolts. Note: The steam outlet of the spray boom should be upward. 4. Install the steam hose. Use a hose clamp to connect one end of the steam hose to the steam outlet of the humidifier host, and the other end to the steam boom, and tighten the hose clamp screws to ensure that No steam leaks. Note: When the steam boom is 300mm away from the top of the humidifier main unit, there must be 20% upward slope and 5% down slope at the height above 300mm; when the steam boom is 300mm away from the top of the humidifier host, Keep the 20% up slope and 5% down slope within this 300mm distance; the shorter the steam hose, the better (* 2 meters in length), the smallest bending radius is 300mm; avoid the steam hose sagging to form a condensation area, If necessary, use pipe clamps and brackets to support the electrode humidifier.
