The Small Guy Does the Big Job－－Damper in Our Powertracker

　　Damper is a hydraulic device that absorbs and damps shock impulses by converting the kinetic energy of the shock into another form of energy which is then dissipated. It has been widely used in the industries of aerospace, aviation, military, firearms, automobile, etc.

　　Powerway’s picks the Two-Way Damper for its Power Tracker to damp and absorb impulses coming from both linear and compressed directions. The damp resistance can be as low as 0 when motion speed is very low; but as soon as the velocity reaches the threshold value, the mechanism will be set off and closed out as a rigid support to perform its offsetting and damping functions.

　　The Damper used in our PowerTracker is mostly made out of Austenitic stainless steel for its characteristics of high corrosion resistance, compact structure, minimal space requirement for installation, and more desirable impact absorbability. It can react to heavy weight with minimal motion-response time. It is hinged at both ends with ball-bearings allowing +/-6 degree range of motion, which enhances its adjustability and flexibility for on-site installation. It uses special hydraulic fluid and sealant for its optimum performance stability and long sealing life.

　　The PV tracking system can be affected by undesirable vibrations (in most cases caused by heavy wind) for the operating stability of its machine and equipment, which in turn shortens its lifespan. The Two-Way Damper is designed to overcome such problem. In the normal working condition, the Damper is set in a retired mode without generating resistance to allow the Power Tracker moving at the normally slow pace; but when nature releases its force causing excessive vibration to the Tracker, the Damper will wake up to exercise its protecting power by absorbing and damping the impetus.
