The invention discloses dry gas seal equipment of a natural gas compressor. The dry gas seal equipment comprises a dry gas seal device, dynamic and static ring assemblies, a non-driving end and a driving end. The non-driving end and the driving end are arranged at the two ends of the dry gas seal device. The multiple dynamic and static ring assemblies are arranged on the outer side of the dry gas seal device. A front seal and a rear seal are arranged in each dynamic and static ring assembly. The upper portion of the dry gas seal device is provided with first-level discharging outlets, second-level discharging outlets, a first guide pipe and a torch. The lower portion of the dry gas seal device is provided with buffer gas inlets, seal gas inlets, isolation gas inlets and second guide pipes. First filters are arranged on the first guide pipe. According to the dry gas seal equipment of the natural gas compressor, the dynamic and static ring assemblies are arranged on the outer side of the dry gas seal device, dynamic rings are made of the SiC material, the material is high in surface hardness, good in abrasion resistance, high in heat conduction coefficient and low in specific gravity, and accordingly, the service life of the dry gas seal device can be prolonged.
Description
technical field [0001] The invention relates to the technical field of dry gas sealing equipment, in particular to equipment for dry gas sealing of natural gas compressors. Background technique [0002] The original shaft seal of 102J natural gas compressor unit adopts differential ring mechanical seal, which belongs to the category of mechanical seal and is a contact seal. Its initial design is to consider that the mechanical seal applied to the high-speed centrifugal compressor has high end surface linear velocity, fast wear and low service life. Therefore, a floating seal ring—differential Ring, to reduce the linear velocity of the friction surface, thereby reducing the requirements for the wear resistance and friction performance of the friction pair material, and achieving the purpose of prolonging the service life of the seal. The differential ring seal has a simple structure and a relatively long service life, so it has been widely used in centrifugal compressors for...
