Actuators have become some of the most pieces of equipment in the modern daily use platforms. Almost all equipmenthasactuators that help the person using them to make less effort in moving the different parts of equipment to achieve a task.There are different types of actuators, ranging from, electric, hydraulic, thermal, pneumatic and mechanical, all of which have different advantages and application depending on the tasks and the specificity of motions possible among other factors. Choosing the right actuator for classroom spaces and equipment requires keen determination of the actuators that will work in different scenarios and the objectives that are set to be achieved.
Table lifts also have some very fundamental roles to play especially in classroom spaces, as they help the users to raise and lower the tables relative to the needs of the individuals and teams.Actuators and lift tables are commonly used together to produce certain movements, which in case of the tables is an upward and downward movement. Lift tables usually have pneumatic or electric powered actuators to initiate the upward and downward movement in an effort to raise the table height and the load on the table or subsequently lower the same.
Choosing the right actuator and left table is crucial, which is primarily determined by the objectives of the classroom. The most common and generic aspects to consider when choosing these equipment include maintenance. In most cases the lift tables apply the use of the linear actuators and one of the main issues associated with these kind actuators is maintenance. The key element in this case is the lubrication and few components to replace.
One other aspect that is important to consider is the aspect of mounting the actuators on the lift tables. The direction of the movement that the actuator is supposed to actuators is supposed to initiate. Linear actuators especially where the movement is in an upward direction with a load is sensitive. This aspect is due to the fact that, the load is also going to exert a downward force and if the system does not offer a braking mechanism to reduce the force as loads are lowered, it could destroy the system and compromise the load depending on the sensitivity. Counter actuators should thus be considered to reduce the pressure on a one actuator and increase the life span of the actuators.
Power source is also an important element to consider. Different actuators will have different power sources ranging from electric, mechanical, hydraulic, pneumatic or magnetic. Choosing between the different means of powering the actuators is important as it will determine the efficiency levels, maintenance costs, durability and responsiveness. Mechanical actuators tend to have a lot of moving parts increasing the chance for a break down, while hydraulic offer limited acceleration. Electric actuators on the other hand are efficient and fast much like the pneumatic and magnetic ones. The choice of the power is relative to the objectives of the individuals or the firm and the tasks at hand.
It is also crucial to consider the length or distance that the actuator will travel to initiate the lift on the table. The length that the actuators have to travel is crucial relative to the effectiveness of the movement the actuator can deliver. Overlooking this aspect will only leave the tasks to be accomplished jeopardized by limited stroke length.
This also ties in with the weight to be carried on the lift tables. Hydraulic actuators are for example quite favorable for lift table that require higher force generation relative to the weight to be placed on the table, while pneumatic ones though fast accelerating are limited to a certain range. The speed and accuracy of the lift generated on the lift tables by the actuators is also crucial depending on the tasks at hand. Choosing a pneumatic linear actuator will guarantee faster responses as the electric ones, with excellent accuracy that is predictable. The hydraulic actuators on the other hand may be slower and less accurate in force delivery and thus movement.
