The use and application of float level controller 2

Abstract: The use and application of float level controller 2 information is provided by excellent flowmeter and flowmeter manufacturers and quotation manufacturers. Float level controllers are widely used, and a similar 'float level controller' has been sold on the market. Used in automatic pumping of water towers. The work has always been normal, and it can also be connected into several automatic control circuits. The following is the controller. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following is the details of the use and application of float level controllers. Float level controllers are widely used, and a similar 'float level controller' has been sold on the market. Used in automatic pumping of water towers. The work has always been normal, and it can also be connected into several automatic control circuits. The following introduces some principles and practical applications of the controller. LPF, type I float controller uses the rise or fall of the float in the liquid to turn on the gravity switch inside the ball, and then the contact switch that is turned on or off inside the float to control the related electrical equipment. The float controller is made of high-insulation, non-toxic, acid and alkali resistant materials, and can be used in water towers and pools such as households, factories and mines, and also in pools, barrels, tanks, tanks for oil, weak acid, weak alkali and sewage. It can be used as a liquid level control switch in such containers. The working principle of the float controller in the well: when the water level in the well rises to the set height. The gravity switch inside the float controller is turned on. At this time, if the water tower is short of water at the same time, the contactor coil is energized, the motor is energized, and the water pump starts to pump water: if the water tower has not been full and the water in the well has dropped to a certain level (the water level that may endanger the safety of the pump). The internal gravity switch of the float controller in the well is disconnected, the AC contactor coil is de-energized and released, and the water pump stops pumping; when the water level in the well rises to the set height. The gravity switch inside the float controller is turned on. When the water tower is short of water, the contactor is pulled in and the water pump continues to supply water automatically. Application example (1) Cooperate with the AC contactor to control the high-power three-phase motor to automatically supply water to the water tower. When the water level of the water tower drops to the set height, the internal gravity switch of the float controller is turned on, the contactor coil is energized and the water pump is closed. Start pumping; when the water level of the water tower rises to a certain height, the internal gravity switch of the float controller is disconnected, the contactor coil is de-energized and released, and the pump stops pumping. (2) The single-phase submersible pump automatically drains the direct control circuit, when the water level rises to the set height. The gravity switch inside the float controller is turned on. When the submersible pump is powered on, it starts to pump water; when the water level drops to a certain level, the gravity switch inside the float controller is disconnected, and the submersible pump is powered off and stops pumping. In this way, the submersible pump realizes automatic drainage. Since the floating ball controller can control the maximum power up to 2kW, it can directly control the submersible pump with low power. For the power exceeding 2kW, it can be used with the AC contactor. (3) Use two float controllers and AC contactors to form a control circuit that can prevent damage to the water pump equipment due to abnormal water sources. How to use (1) Pass the cable of the float switch through the central hole of the weight, and gently push the weight to the desired range of liquid level control. The longer the cable from the weight to the float is left. The height difference of the control liquid level is also larger. (2) The heavy hammer should be fastened with the matching plastic ring. In order to prevent the weight from sliding and affecting the control of the liquid level. It is best to tie the upper and lower ends with a copper wire. (3) The cable is directly pulled to the control box, avoiding joints in the middle. If there is a joint as a last resort, never immerse the joint in the liquid. (4) The unused wire ends should be wrapped with insulating tape. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
