Problems solved by technology
[0002] After more than a year of high-load operation of the ship and machinery shaft seal, the oil-water seal must be renewed, otherwise it will directly affect the normal operation and economy of the ship and machinery, and at the same time play a very important role in environmental protection of water and other environmental pollution , so it is necessary to replace the new oil-water seal, but the original oil-water seal position has groove marks due to long-term wear, and the new oil-water seal cannot achieve the expected effect after installation

The invention provides a shafting seal adjustable wearproof durable device. The shafting seal adjustable wearproof durable device comprises a double-cone wearproof locking sleeve and a rotary spindle.A body of the rotary spindle is sleeved with a vehicle bearing copper sleeve, the portions, at the two ends of the vehicle bearing copper sleeve, of the body of the rotary spindle are sleeved with conical locking oil seals, the surfaces of the conical locking oil seals are sleeved with wearproof sleeve locking nuts, the peripheral face of the vehicle bearing copper sleeve is sleeved with a bearing copper sleeve positioning casing pipe, and the portions between the end of the bearing copper sleeve positioning casing pipe and the wearproof sleeve locking nuts are sleeved with trapezoidal oil seal nuts. The portions between the inner ends of the trapezoidal oil seal nuts and the bearing copper sleeve positioning casing pipe are connected and sealed through adjusting locking nuts, and the portions between the inner cavity walls of the outer ends of the trapezoidal oil seal nuts and the peripheral faces of the wearproof sleeve locking nuts are sealed through trapezoidal sand blocking waterseals and trapezoidal oil seals. The shafting seal adjustable wearproof durable device is reasonable in structure and capable of being adjusted multiple times to be used.
Description
technical field [0001] The invention relates to the technical field of shaft seals for ships and machinery, in particular to an adjustable wear-resistant and durable device for shaft seals. Background technique [0002] After more than a year of high-load operation of the ship and machinery shaft seal, the oil-water seal must be renewed, otherwise it will directly affect the normal operation and economy of the ship and machinery, and at the same time play a very important role in environmental protection of water and other environmental pollution , In this way, a new oil-water seal must be replaced, but the original oil-water seal position has groove marks due to long-term wear, and the new oil-water seal cannot achieve the expected effect after installation. Contents of the invention [0003] The object of the present invention is to provide an adjustable wear-resistant and durable shaft seal with reasonable structure and good use effect. [0004] In order to achieve the...
