• What is a valve actuator?

    At present, the common implementing agencies such as: pneumatic, electric, hydraulic, gas-liquid linkage, electro-hydraulic linkage. Hydraulic movement mainly refers to the unified setting of an oil station, and then the oil is distributed to each hydraulic actuator, mainly used in the factory more dense valve area. Gas-liquid linkage is often used in dispersed areas and is not easy to lay cables, and the medium in the pipeline is compressed gas (such as the west-to-East gas pipeline), using the compressed gas…

  • Principles of Switching and Adjustable Electric Valve Actuators

    Electric actuator in the control mode, there are two kinds of switching electric actuator and adjustable electric actuator, many customers do not understand the switch type and adjustment type of different, the main difference is that the valve switch control function is different. 1, switch type electric actuator switch type electric actuator is also known as open-loop control electric actuator, this actuator in the execution of valve operation only open, off two actions, that is, can only make the valve…

  • Teach you to understand the electric actuator wiring diagram

    First of all, to figure out the meaning of the various logos, and then understand the connection method, and then learn to see the different styles of the map. Electric valve actuators can be divided into AC (AC110V, AC220V, AC380V) and DC (DC24V, DC12V) according to the power supply voltage. They are divided into active switch type, passive switch type, potentiometer type and regulation type according to the control mode. Through the different wiring diagrams below: 1, active switch type,…

  • What are the specifications of the electric actuator? How to distinguish between

    The electric actuator is mostly matched with the valve and is used in the automatic control system. There are many kinds of electric actuators, different in the way of action, such as the angular stroke electric actuator is the output corner torque, and the straight stroke electric actuator is the output displacement thrust. The type of electric actuator used in the system should be selected according to the working needs of the valve. The types of valves themselves are quite…

  • What are the control methods for electric actuators?

    The valve controller is actually called the positioner, which is the brain of the valve. The position signal is collected by the feedback lever, the signal is processed, and the corresponding signal is output to the actuator. The electric actuator in the actuator is the hand of the valve, receives the air pressure from the locator, then produces the displacement, through the displacement to control the opening of the valve. Valve type is quite a lot, the working principle is…

  • What is the difference between an intelligent electric actuator and an intelligent integrated electric actuator?

    Now the intelligent electric actuator has not been well recognized specifications, but the basic definition has now been consistent. The performance of intelligence is mainly in several ways: 1. No open cover debugging. 2. With human-computer interface. 3. Torque detection selection of motor current detection methods. 4. Azimuth sensor selection encoder (split relative encoder and positive encoder) 5. The function of self-diagnosis with faults. 6. With bus interface (multiple protocols optional) and so on. Intelligent integrated electric Actuator is shown…

  • What are the relevant parameters of the valve electric actuator?

    Valve electric Actuator is divided into two categories of straight stroke and angular stroke. The electric actuator is powered by a power supply, which is mainly used for the control of valve opening and closing, as well as for the flow regulation control of the piping medium. Basic parameter performance of the electric actuator: 1, control voltage: ac220v50/60hz, dc24v, ac380v, dc220v or specify other. 2, the output torque of the electric actuator: according to the valve on or off when…

  • Problems to be aware of when purchasing imported electric actuators

    1. Drive energy The most commonly used electric actuator drive energy source is a power source or a fluid source. If the power source is selected as the drive energy source, a three-phase power source is generally selected for a large-sized valve, and a single-phase power source can be selected for a small-size valve. General electric actuators are available in a variety of power types. Sometimes DC power can be selected, and the battery can be safely operated by installing…

  • Three maintenance methods for valve electric actuators

    Valve electric devices, like the electrical equipment used in our daily life, must also be cleaned and maintained to achieve longevity. Our staff must ensure that the equipment is in a state of cleanliness, good lubrication, complete valve parts and normal operation. The following are some of the maintenance methods introduced: 1. Lubrication of valve electric actuator: trapezoidal thread of valve electric device, sliding part of stem nut and bracket, bearing part, meshing part of gear and worm wheel, worm…

  • Electric actuator application analysis

    Electric actuators, also known as electric actuators. It is a drive that provides linear or rotational motion that uses some kind of drive energy and works with some kind of control signal. The utility model has the advantages that the energy is convenient to use, the signal transmission speed is fast, the transmission distance is long, the centralized control is convenient, the sensitivity and the precision are high, the electric adjustment instrument is convenient to cooperate, and the installation wiring…
