Wuxi Xinming automatic control valve industry to introducePneumatic actuatorHow to solve the problem that the voltage indicator light does not light up after power on.
Pneumatic actuator, kneaded aluminum alloy cylinder body, after hard oxidation treatment, the appearance of hard texture, strong wear resistance. Compact double-piston gear, rack-type structure, accurate meshing, smooth transmission, symmetrical device orientation, stable output torque. The active parts of the piston, rack and output shaft are equipped with F4 guide rings to complete low conflict, long life and prevent metal contact. After power on, the voltage indicator does not light up, the servo board has no feedback, and the signal does not act. For maintenance methods, it is necessary to check whether the safety tube is open. If it is in good condition, check whether the power supply of the servo board is in good contact. If it is normal, check the power indicator again. If the indicator is open with a multimeter, it indicates that the indicator is faulty. When the actuator is powered on during the operation and debugging of the fault 2., the valve can be opened but not operated when it is closed. For maintenance methods, first check the feedback line. If there is no fault, the indicator light is on when the signal is turned on, indicating that it is normal. When the signal is turned off, the indicator light is not on, indicating that there is a problem with the off-SCR part. Check the indicator light, use a multimeter to check the off indicator light, open circuit, and return to normal after replacing the thyristor.
Under normal circumstances, the choice of pneumatic actuator is to consider multiple factors, such as the use of the valve conditions, the use of temperature, operating frequency, management and pressure, transmission medium (lubrication, drying, mud), etc., in the selection of pneumatic actuator In the process, the main points are the following. The cylinder body, end cover, output shaft, tension spring and fastener are all treated with anti-corrosion treatment. The tension spring of the single air-controlled actuator can be safely and conveniently disassembled and assembled after being pre-pressed. AT32 pneumatic actuators can be fully open and fully closed orientation 0 degrees and 90 degrees plus or minus 5 degrees of two-way stroke conditioning. The connection size of the device conforms to ISO5211, DIN3337, VD1/VDE3845 and namur standards, ensuring the interchangeability between AT32 pneumatic actuators and facilitating accessories such as solenoid valves and limit switches. The device connecting hole of the output shaft has a variety of shapes (square hole, shaft key hole, flat hole) for selection, beautiful and exquisite appearance, light weight, and waterproof and sealed structure. As one of the opening and closing device, the pneumatic actuator installed on this valve uses compressed gas to push the piston to play a role in the valve stem connected to it, and drive the ball valve to move, thus playing a role in adjusting the fluid medium in the pipeline.
As one of the opening and closing parts, this ball around the axis of the ball valve for rotation, for the transport of the medium has a certain effect. Ball valve is characterized by wear resistance, good sealing performance, and because of the smaller resistance, so the internal valve body by less wear, service life is relatively long, this feature makes the use of this pneumatic valve in the pipeline comparison "handy".
Pneumatic actuatorThe switching action of the actuator is driven by the air source, which is called DOUBLE ACTING, which is double-acting. The SPRINGRETURN, that is, single-acting, only on or off is driven by the gas source, and the opposite action is returned by the spring.
