Good stability: the stability of the motor is good, and it can run stably in a variety of harsh environments.
Easy integration: It can be seamlessly integrated with a variety of control systems to achieve remote monitoring and automatic control.
Energy saving and environmental protection: Low energy consumption in the operation process, and no manual intervention, helping to save energy and reduce emissions.
3. How it works
The working principle of the electric gate is to drive the transmission mechanism through the motor, so that the gate moves along the predetermined track, so as to realize the opening and closing of the gate. Specifically, when the control system receives an external signal, it calculates the desired torque and speed according to a preset program and sends instructions to the motor. The motor rotates according to the instruction and transmits the power to the ram through the transmission mechanism, so that the ram moves along the predetermined track. At the same time, the sensor will monitor the position and status of the ram in real time and feed the information back to the control system. The control system adjusts the output of the motor according to the feedback information to ensure that the ram reaches the specified position accurately. In addition, some advanced electric gates are also equipped with safety protection devices, such as overload protection, limit switches, etc., to ensure the safe operation of the equipment.

5. Application field
Industrial field: Used for fluid transportation and control in chemical, petroleum, pharmaceutical and other industries. In these industries, the flow rate, pressure and other parameters of the fluid need to be precisely controlled to meet the requirements of the production process. The electric gate can meet these requirements through its high precision control performance.
In agriculture: water flow control in irrigation systems. In modern agriculture, irrigation systems are becoming more and more intelligent, requiring precise control of water flow to improve irrigation efficiency and conserve water resources. The electric gate can automatically adjust the water flow according to the soil moisture, crop water demand and other factors to achieve precise irrigation.
Water conservancy field: Used for water flow control in water conservancy projects such as reservoirs and hydropower stations. In these projects, water flow needs to be precisely regulated to meet the needs of power generation, flood control and so on. The electric gate can realize remote monitoring and automatic control, and improve the management efficiency and safety of water conservancy projects.
Other areas: fluid transfer and control in industries such as environmental protection and water treatment. In these areas, it is necessary to treat and discharge sewage, waste water, etc., and electric gates can achieve precise control of fluid flow to meet environmental protection requirements.
