1. Classified by power source Depending on the type of power source, the valve drive can be divided into four types of manual, pneumatic, hydraulic (hydraulic pressure or water pressure) and electric (electromagnetic or motor) drive.
The content of comprehensive maintenance of pneumatic butterfly valve mainly includes the following aspects:
Hydraulic aerodynamic actuators utilize pressurized gas or liquids to achieve linear motion and have the largest output potential. These systems include a piston, which is in a sealed tube, and both ends have valves. The piston is connected to an actuator rod, and the rod passes through the seal at one end of the tube.
Such an actuator converts the rotational energy of the motor into a straight movement using a cam or a lead bar device. The screw example is a very popular choice because it provides a wide range of extended length potentials.
Linear actuators have a quantity of amazing processes, machines, and devices that provide linear drives. These devices from inconspicuous DVD tray openers to produce tens of thousands of pound of pressure giant hydraulic plunger.
A linear actuator is any device that generates work by converting nonlinear energy in linear motion. There are many primary energy sources used in linear actuators, from electric motors to fluid and air pressure and thermal expansion.
