The spring washer is used for locking. The flat washer has no locking function. The flat washer only increases the contact area
The flat pad only increases the contact area, and the spring pad can avoid loosening. For example, the bolt connecting the motor and the base should be added with spring pad, because if the motor vibrates without spring pad, the nut will loosen. The fasteners on the equipment with vibration are equipped with spring gaskets, and the flanges do not need to be added with gaskets! Whether to add a spring gasket to the flange is related to the medium flowing through the pipeline. If it is easy to produce pulses, add a spring gasket, and the fluid and diameter change frequently On some valves, the gland flange of the stuffing box needs spring gaskets The automatic selection of spring gasket is included.
The flat pad is used to increase the fastening contact area Spring pads are used where there is vibration to avoid loosening No spring gasket is required for fastening PVC flange. The flat pad increases the contact area and avoids the friction between the bolt and the workpiece; The spring pad is to avoid vibration and looseness;
The flat washer is used to protect the surface of the connector to avoid scratching the workpiece surface when the bolt and nut are tightened; The spring washer is anti loose. However, for some important connections, such as those that rely on compression to generate friction to transmit power, spring pads cannot be used. If they are used to reduce the rigidity of the connection, it is easy to cause accidents. Spring washers may not be used. When the strength of the connected part is low, the flat gasket or flange bolt shall be used to increase the contact area. The flat gasket is used to increase the contact area, and the spring gasket is anti loose. In case of vibration, pulse and large fluctuation of medium temperature, the spring gasket shall be used. The spring washer can increase the pre tightening force and has anti loosening effect, while the flat washer does not.
