Description
TECHNICAL FIELD
[0001] The utility model belongs to pneumatic actuator technical field especially a dustproof device of pneumatic actuator. BACKGROUND
[0002] Pneumatic actuator is a kind of device using compressed air as power source, and it is converted into mechanical energy, mainly used to realize linear or rotary motion, to drive valve, mechanical arm, fixture and other equipment to complete switching, regulation or positioning action. It is one of the common execution mechanisms in industrial automation field. As the core driving component of industrial automation system, the running stability of pneumatic actuator is closely related to the heat dissipation performance. In the prior art, most of the pneumatic actuators are cooled by setting heat dissipation plates (such as aluminum fins or rib plate structure) outside the shell, and the working temperature of internal elements is reduced by air convection.
[0003] However, in the industrial environment with more dust, fiber and other pollutants (such as foundry workshop, wood processing plant), the surface of the heat dissipation plate is easy to adsorb dust particles and form a covering layer. Long-term operation, dust accumulation not only blocks the gap between the heat dissipation plate and hinders air flow, but also significantly reduces the heat dissipation efficiency due to the heat insulation effect of dirt, which leads to the problems of internal temperature rise of the actuator, aging of sealing material, lubrication failure and even cylinder blocking. Therefore, how to realize the active dust prevention of the heat dissipation structure of the pneumatic actuator without affecting the heat dissipation performance has become a technical problem to be solved.
