Do You Want to Know the Types of Actuators

An actuator for sale is a mechanism utilized in the manufacturing of machines and equipment to promote valves needed to cease or start a function. Moreover, a vital part in machines, such as computer-operated machines or audio equipment, actuators for sale can use fluid, air or electric current to facilitate motivation. What’s more, electric actuators for sale generally can be divided into one of two categories: acoustic system or haptic system. But the following are the specific types of actuator for sale.

Hydraulic Actuators

Hydraulic actuators should cooperate with minimal mechanical parts. Moreover, they make use of liquid to pressurize pistons used to promote mechanical operation. As hydraulic fluid cannot be compressed, hydraulic actuators traditionally cost longer time to obtain speed and power while needing more time to give up. As they are more commonly used over longer time in power equipment that will go steadily with rare stops, they can also be equipped with fail-safe traits to allow quick stops for emergency situations.

Pneumatic Actuators

Pneumatic actuators also operate with minimal parts, but differently they use air to pressurize pistons. As air can be compressed, pneumatic actuators do not need regulation. As the power source does not require being stored in reserve for operation, pneumatic actuators can answer quickly in starting and stopping, which let them look more ideal for mechanical equipment that requires frequent changes in pressure to complement a result that has been planned before.

Linear Actuators and Lorentz Actuators

Acoustic system actuators can make high frequency vibrations most commonly used to enhance or extend sound through the air or structures. What’s more, vibrations in the air are commonly driven by linear actuators that alter electrical signals into pressure waves in the air. Moreover, Lorentz actuators depend on electric current and magnetic presence to hold activity. Moreover, this actuator type can utilize a lot of forces and is often used in applications needing high bandwidth motion, while acoustic system actuators are most commonly used in loudspeakers and other audio equipment.

Haptic System Actuators

For Haptic system actuators, they are designed to make slower vibrations at lower frequencies than what is needed with acoustic systems. Moreover, most commonly used in products that need communication with the human motor system, haptic system actuators are different from acoustic actuators as they can be initiated by connecting with a pressurized force like air, fluid, manual effort or electric motor. In addition, several actuators for sale that falls into this category type including manual, hydraulic or electric actuators.

Manual and Automatic Actuators

Manual actuators use levers, gears or wheels to promote movement. At the same time, automatic actuators are usually connected to an external electrical power source to create force and motion. Moreover, manual actuators are used for smaller valves and equipment while automatic actuators power large valves that need more horsepower to function. What’s more, automatic actuators also work well in situation where manual force to operate valves may prove toxic or dangerous to people.

Electric Actuators

Electric actuators are powered by a motor that promotes torque to operate the valves in mechanical equipment. At the same time, electric actuators are commonly used when equipment needs multi-turn valves like gate or globe valves. What’s more, since these valves are used on platform that is used usually in machines with constant converts in activity, these actuators for sale can be fairly busy. However, they also need a battery backup to guaranteed safe operation should electric current somehow be banned.
