Product introduction

pring washers are used to prevent loosening, such as bolts connected with the motor and the frame, usually with spring pads, because the motor vibration if there is no spring pad, the nut will loosen. Generally, the fasteners with vibration are equipped with spring gaskets, and the flange generally does not need to add gaskets! Flange with or without spring gasket and pipeline flow medium has a relationship, if it is easy to produce pulse, it is best to add spring gasket, as well as high-speed fluid, caliber changes frequently. Do not generalize. On some valves, stuffing box gland flanges require spring gaskets. Automatic selection of spring gasket is included.

Spring washer can play a loose, increase the function of pretightening force, and flat washer does not have this function, it can be used to increase the fastening contact area, prevent the friction between the bolt and the workpiece, protect the surface of the connector to prevent scratching the workpiece surface when the bolt and nut tighten.

But some important connections, such as mainly rely on compression friction to transfer power, is not the use of spring pads, with the reduction of connection rigidity, the accident is easy. You don’t need a spring washer. When the strength of the connecting piece is low, the flat pad or flange bolt is used to increase the contact area. When there is vibration, pulse, and the temperature of the medium, the spring pad must be used.
