The various parts of the photovoltaic support are connected by fasteners to ensure the stability of the entire photovoltaic support, but don’t underestimate such a small fastener. If it is used improperly, there will be problems. Give the photovoltaic support The construction caused trouble. One of the most common ones is that the fasteners are locked, causing the bolts and nuts to be unable to separate. Can this problem be avoided?
Through the analysis of the reasons for the locking of the fasteners on the photovoltaic bracket, we have reached this conclusion. Although the fasteners are mostly made of stainless steel, they have good corrosion resistance. If the surface is damaged, a layer will also be produced. A thin oxide layer prevents further corrosion. When the fastener is in the locked state, the pressure and heat generated between the teeth will destroy this oxide layer, and then the adhesion phenomenon will occur until it is completely locked.
If the fasteners can be used correctly, this problem may be effectively prevented. Before use, try to ensure that the surface of the fasteners is smooth and wax-dipped; when using it, it must be screwed and cut perpendicular to the axis of the thread. Do not tilt; and the force must be even, the tightening torque must not exceed the safe torque; at the same time, the speed and force of the screw must be appropriate.
In addition, do not use fasteners under high temperature conditions, or use washers to effectively prevent the fasteners from being over-tightened. It is one of the more effective ways.
