Description

Mechanical sealing designs device

Technical field

The utility model belongs to technical field of sealing technology, and in particular to a kind of mechanical sealing designs device.

Background technology

In mechanical field, most machine operations is all to drive to have enough to meet the need by motor, in mechanical circular flow, Friction can be produced, heat and abrasion is produced, lubricating oil and cooling oil are often used the connecting portion in a variety of connecting shafts, power transmission shaft Point, allow lubricating oil or cooling oil to be sealed in friction part critically important, it is to avoid lubricating oil or cooling oil leakage, cause lubricating oil or Cooling oil is wasted, also serious air pollution, and especially in engineering shop, lubricating oil or cooling oil are leaked, can be very big The working environment and air in worsening degree workshop can, very big actual bodily harm is brought to operating personnel, it is seen then that mechanical seal is outstanding Its is important, and traditional mechanical seal uses gasket seal or sealing ring, but on the axis of rolling, sealing ring or gasket seal are very Easily it is worn, service life is very short, it is necessary to which the cycle changed is short, it is easy to reveals in lubricating oil or cooling oil, workshop and shuts down Sealing ring or gasket seal are changed, production efficiency is influenceed.

The content of the invention

Embodiment

The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings：

As shown in figure 1, a kind of mechanical sealing design device, mechanical sealing design device, including sealing device Body, sealing device body 1 includes axle sleeve 7 and cooperated for sealed rotating ring 4 and stationary ring 2；The stationary ring 2 is fixed on pressure In lid 13；Fixed locating ring 6 on the axle sleeve 7；The fixed spring 5 in the front end of locating ring 6；The front end of spring 5 is set There is spring base 9；The spring base 9 is connected and fixed on housing 14；The fixed rotating ring 4 of the interior side of housing 14；The rotating ring 4 Seal ring of moving ring 11 is provided between the axle sleeve 7；Stationary ring sealing ring 3 is provided between the stationary ring 2 and the axle sleeve 7；It is described Gland 13 is fixed on the housing 14 and the axle sleeve 7；One end of the axle sleeve 7 is internally provided with sleeve sealing circle 8, described The other end of axle sleeve 7 through the locating ring 6, the spring 5, the spring base 9, the dynamic seal ring 11, the rotating ring 4, The static sealing ring 3 and the gland 13；Rubber layer provided with elasticity between the spring 5 and spring base 9；Set on the housing 14 It is equipped with screw perforation 12；The sealing device body 1 is constituted using etch-proof alloy material；The gland and the rotating ring Between be provided with flexible member；The flushing hole that section is V types is offered on the outside of the gland.

The utility model is used for the demand for meeting mechanical seal, and annexation is stable, and mechanical seal function well uses the longevity Life length, No leakage, the mechanical sealing design device for being not required to artificial long term maintenance, and ensure axle and axle sleeve without abrasion.Radiating Performance is good, torque is small, is unlikely to deform, spring change, it is easy for installation；The setting of rubber layer greatly reducing spring and spring base Between friction.

Operation principle：It is close to by two bright and clean, accurate planes in the presence of external force, mutually and fortune for the relative rotation The dynamic sealing device that dynamic face is constituted.Main function is static seal and the end that the axial seal for being easier to leakage is changed into more difficult leakage Face is sealed.An appropriate compression is produced on the rotating ring of relative motion and the contact surface of stationary ring by flexible member and fluid pressure Power is so that the two end faces are brought into close contact.
