How to make a water level controller, the purpose of the water level controller

Required components: AC contactor, intermediate relay, circuit breaker (air open or knife switch), travel switch, start button, stop button. There are a number of square copper core plastic wires, a float, a metal tube (and the float constitutes a lever), or without a metal tube, with pulleys and nylon ropes.

and a short section of angle iron (fixed lever or pulley and travel switch). In addition, there are a number of wooden nails or mechanical nails. Furnace analyzer distribution box or distribution board one (block), fixed circuit breaker, contactor, relay, and button.

Working principle: The circuit breaker controls the main power supply and control circuit. Two travel switches (one upstroke and one downstroke) control the relay coil, and the relay controls the contactor coil.

The contactor is connected to the main power supply to control the motor. The start button and the lower stroke are connected in parallel, and the stop button is connected in parallel with the upper stroke.

The water level controller refers to the control of high and low water levels through mechanical or electronic methods, which can control solenoid valves, water pumps, etc., and become automatic water level controllers or water level alarms, so as to achieve semi-automation or full automation.

Scope of application: The water level controller is widely used in industrial boilers, civil building pools, water towers, water tanks, as well as petrochemical, papermaking, food, sewage treatment and other industries in open or closed storage tanks, underground pools in various liquid level measurement, the detected medium can be divided into water, oil, acid, alkali, industrial sewage and other conductive and non-conductive liquids. It forms a set of advanced liquid level display and control equipment with electric valves, which automatically opens and closes electric valves.

Water level control, what you make can only be played in the laboratory, because you ignore the actual situation, there are impurities such as scale and moss in the process of use, which is not encountered in the laboratory. If you don't get it right, you burn the pump, you waste water, and the gains outweigh the losses. You can get it yourself, how can you spend so much manpower and material resources on the research and development of things by regular manufacturers, and think comprehensively.

Teach you a trouble-saving method: use the leakage protector, there is a test button on it, open it to find the corresponding two metal pieces in the test button, lead out two wires to the top of the water tower, make a float with contacts, connect the two wires to the contacts respectively, pay attention to the contact wiring do not touch the ground or contact the water, the water surface height is adjusted by yourself, the leakage protector action when the contact contacts, and the switch will automatically power off.

Depending on your situation, the easiest thing is to make a float valve with a limit switch!! The limit switch is connected in series to the coil of the contactor! Floats you can use plastic bottles!

You just tossed around, I saw it last night, and I ignored you. Buy a float level controller, 30-50 yuan, and connect the pump according to the instructions. The three-phase motor just adds a contactor.

It's safe and secure. This thing has no technical content at all, what is there to study?

There is this product sold on the market, but also with no water protection function, will not cause the pump to idle, Wuhan Yuxing water level controller factory production, can be searched on the Internet, I have used, only forty yuan a, why bother to do it yourself,

Located in Yongfeng High-tech Industrial Base, Haidian District, Beijing, Beijing Jingbo Instrument Co., Ltd. is a high-tech enterprise integrating scientific research, design, production, sales and system integration. With first-class product quality and superb technical service, it has been well received by users. In the process of development, the company has continuously communicated and cooperated with many scientific research institutions at home and abroad, and its design, production, maintenance, commissioning and engineering supporting capabilities have been rapidly improved.

At present, we have established a branch in South Korea, and we have a number of partners in Korea, Denmark, Iran, and India, and the company's production scale is also expanding.

Control the alarm or solenoid valve or control the automatic water supply and automatic drainage of the water pump.

The principle of the water level controller:

The water level controller generally measures the water level through the water level sensor, and then transmits the signal to the display controller, and then the controller transmits the switch signal to the electric actuator, and finally the electric actuator switches on and off the water pump.
