Abstract

The invention relates to an elastic sealing element for reciprocating dynamic equipment and a sealing method thereof. The elastic sealing element for reciprocating dynamic equipment has an annular cavity, and the annular cavity is placed outside by an inner cylinder. Inside the cylinder, and the two ends of the inner cylinder and the outer cylinder are closed respectively, and the outer cylinder is provided with an injection pipe, and a check valve is arranged in the injection pipe. Both the inner cylinder and the outer cylinder are made of elastic materials; In addition to the sealed internal equipment, the external equipment that needs to be sealed is surrounded by the annular cavity, and the liquid is injected into the annular cavity through the injection pipe, so that the inner surface of the inner cylinder and the outer surface of the outer cylinder are in contact with the sealing surface with relative movement. , when the sealing surfaces slide relative to each other, the ring-shaped cavity completes rolling through its own deformation under the action of shear force, and uses rolling friction instead of sliding friction. During use, the elastic sealing element of the present invention does not generate sliding displacement with a relatively moving sealing surface, thereby improving the airtightness of the equipment and the stability of the operation of the equipment.

Description

Technical field: [0001] The invention relates to the sealing technology of reciprocating dynamic equipment in the field of mechanical engineering and mechanical equipment, and specifically relates to an elastic sealing element and a sealing method for reciprocating dynamic equipment. Background technique: [0002] Sealing is a necessary measure to prevent the leakage of the working medium inside the equipment or the entry of external media, and it can be used for gas, liquid, solid powder and other media. Adverse effects such as poor equipment sealing scheme or poor airtightness will cause low equipment operation efficiency, increase wear and tear of parts, affect product quality, and waste resources. important impact on safety. [0003] Sealing can be divided into static sealing and dynamic sealing according to specific working conditions. Generally speaking, there is no relative moving surface under static sealing working conditions, and the airtightness requirements can ...
