Description

Technical Field

[0001] The utility model relates to the technical field of mechanical seals, in particular to a mechanical seal that is easy to disassemble, assemble and repair. Background Art

[0002] Mechanical seals are sophisticated, complex, and fundamental mechanical components. They are devices that prevent fluid leakage by maintaining contact and sliding relative to each other under the influence of fluid pressure, the elastic force (or magnetic force) of a compensating mechanism, and the cooperation of auxiliary seals. The sealing surface, one of the most critical components of a seal, is typically made of wear-resistant and corrosion-resistant materials. It contacts and forms a seal with another sealing surface. The sealing performance and service life of a mechanical seal depend on many factors, such as model selection, machine precision, and proper installation and use. Mechanical seals achieve a sealing effect by trapping fluid within the sealed area through friction and pressure between the sealing surfaces. Seals are commonly used in various rotating and piston equipment, such as liquid pumps, compressors, mixers, and centrifuges, to prevent leakage during operation and extend the equipment's service life.

[0003] Existing mechanical seals that are easy to disassemble and repair are not convenient for cooling down the mechanical seals during actual use, thereby reducing the heat generated by friction and thereby slowing down the wear of the seals.

[0004] After searching existing patents, it was found that a mechanical seal (publication number: CN214466095U) includes a dynamic ring, a sealing ring, a static ring and a spring. The sealing ring is embedded in the outer side of the dynamic ring, and a static ring is provided on one side of the dynamic ring. A protective layer is provided inside the connecting column, and a heat insulation layer is provided on one side of the connecting layer. A buffer layer is provided on one side of the heat insulation layer, and a reinforcement layer is provided on one side of the buffer layer. The utility model adopts a multi-layer design of a protective layer, a heat insulation layer, a buffer layer and a reinforcement layer through the connecting column. The protective layer makes the external structure of the connecting column more solid, the heat insulation layer reduces the heat received by the seal to prevent deformation and rupture due to excessive temperature, the buffer layer cushions the vibration of the mechanical equipment to prevent excessive vibration force from damaging the seal, and the buffer component on the inner wall of the dynamic ring contacts both sides of the connecting column. The buffer pad, elastic column and elastic member are used in combination to cushion the force on both sides of the end of the connecting column to prevent the connecting column from rupturing and affecting the use of the mechanical equipment.

[0005] Although the above patent achieves the goal of buffering the forces on both sides of the connecting column end by combining a buffer pad, an elastic column and an elastic part to prevent the connecting column from breaking and affecting the use of mechanical equipment, it is not convenient to disassemble the mechanical seal, reduce the difficulty of inspection and maintenance, and reduce maintenance time.

[0006] Therefore, it is necessary to invent a mechanical seal that is easy to disassemble and overhaul to solve the above problems. Utility Model Content

[0007] The technical problem solved by the utility model is to provide a mechanical seal that is highly practical, can be easily disassembled and repaired through simple operations, and has a relatively simple structure, thereby solving the problems of the inconvenience in cooling and disassembling the mechanical seal raised in the above-mentioned background technology.

[0009] As a further solution of the present invention, the limiting assembly includes a movable rod slidably connected to the inside of the fixed sleeve, the surface of the movable rod is sleeved with a limiting ring, and one side of the limiting ring is fixedly connected to a telescopic spring, which facilitates pushing the movable rod.

[0010] As a further solution of the present invention, the delivery assembly includes a water pump connected to one end of the cooling pipe, and the output end of the water pump is connected to a water tank, which is convenient for storing coolant.

[0011] As a further solution of the present invention, a protective shell is fixedly connected to one side of the support seat, and a ball is slidably connected to one end of the fixed sleeve, so that the ball can slide easily in the fixed sleeve.

[0012] As a further solution of the present invention, a sealing sleeve is sleeved on the surface of the shaft sleeve, and a steel washer is sleeved inside the sealing sleeve, and the steel washer is convenient for supporting the pressure spring.

[0013] As a further solution of the present invention, a plurality of groups of pressure springs are fixedly connected to one side of the steel washer, and a moving coil is fixedly connected to one end of the pressure spring, and the moving coil is convenient for increasing the sealing performance.

[0015] As a further solution of the present invention, a groove adapted to the ball is provided at one end of the movable rod, and a connecting seat is fixedly connected to one side of the base, which facilitates docking and fixing of external equipment.

[0016] The utility model provides a mechanical seal that is easy to disassemble, assemble and repair, and has the following beneficial effects:

[0017] 1. The mechanical seal, which is easy to disassemble, assemble and repair, is provided with a conveying assembly and a semiconductor refrigeration plate.

Through the setting of the limit assembly, when disassembly is required, the movable rod in the fixed sleeve is pressed to make the movable rod slide in the fixed sleeve, and the limit ring squeezes the telescopic spring to deform under force, and then the ball slides from the fixed sleeve to reach the groove on the movable rod. The sealing cover is pulled to pull the fixed sleeve out of the socket, thereby achieving the effect of convenient disassembly of the mechanical seal, reducing the difficulty of overhaul, reducing maintenance time, and improving the convenience of the mechanical seal.
