The spring energy storage sealing ring has good chemical inertness, wide temperature resistance range, small friction coefficient and small starting friction, but it is easier to wear and creep than other PTFE filled seals. Used in low temperature, light load, chemical, food and pharmaceutical industries. The color is white. Operating temperature (+260℃ to -196℃). It has good physical properties, good wear resistance and creep resistance. This is a common material. It requires low hardness of working surface and has certain grinding effect on soft metal. Mainly used for high speed, short stroke, high pressure reciprocating movement and medium load. The color is taupe. Operating temperature (+260℃ to -196℃).

It has good wear resistance and self lubricating properties, and is used as a good material under heavy loads without lubrication. The color is; Black operating temperature (+260℃ to -196℃). It is a standard sealing material for hydraulic system of walking machinery and rotating motion occasions. Suitable for medium load, the working surface hardness requirements are lower than F102. The color is black (+260℃ to -196℃). There is no hardness requirement on the working surface. Widely used in stainless steel, aluminum, bronze and other soft metal materials. The color is beige (+260℃ to -196℃).

Spring energy storage sealing ring installation requirements:

1. Please read this manual before installation and use, and pay special attention to safety precautions.

2. The use and operation of the seals shall be equipped with corresponding protective facilities to avoid pollution and personnel injury to the surrounding environment due to the failure of the seals. Operators who install and use mechanical seals must be trained and qualified.

Check items before assembly of spring energy storage sealing ring:

1. It is necessary to check whether the mechanical seal installed is suitable for your operating conditions. When the temperature of the transmission medium is too high or too low, or contains flammable, explosive and toxic foreign bodies, corresponding measures should be taken, such as plugging, washing, cooling and filtration.

2. Check the accuracy of relevant hazard marks, mounting and connection dimensions, and important axial and radial dimensional tolerances on the shaft and cavity.

3. Carefully read the mechanical seal assembly drawing (reference product sample for standard series products) to ensure the installation dimensions and tolerances of mechanical seals.
