The mechanical sealing device forms an assorted integrated seal device and is convenient to transport, mount and use; the water seal device has good sealing property and high bearing capacity; the sealing property of the water seal is guaranteed; and the working condition of the mechanical sealing device is improved.
Description
Affiliated technical field
what the present invention relates to is shaft mechanical seal and water cooled seal device.
Background technique
In various device, particularly pump seals normal use mechanical seal device to axle, in order to carry out cooling to mechanical seal device, need to pass into cooling medium carries out cooling as the heat that water etc. produces mechanical sealing friction pairs, be called " chilling " or " carrying on the back cold ", also that the crystalline particle gathering, dirt removal is clean when the media such as water are cooling to mechanical seal device, it is water seal mechanism that auxiliary seal so just need to be set on hubcap.Generally chilled water (chw) carries out cooling or flushing work from gland inner chamber is injected in inlet opening, then from delivery outlet, directly naturally emits, and this has obviously caused the waste of cooling water.In some industry, if petrochemical industry is along with water saving reduces costs the raising with environmental protection consciousness, requirement, require chilled water (chw) to reclaim after using, recycling after purifying.Various water seal arrangements originally can only play and necessarily prevent the effect of overflowing, and can not realize seal request, chilled water (chw) is access in after reclaim line system, because quench liquid is discharged resistance increasing, pressure increases, and makes quench liquid spill even ejection from the gap of water seal, and the bearing capacity of existing various water seal mechanism is low, sealing is low, can not guarantee
the usage requirement of zero leakage.
Summary of the invention
The object of this invention is to provide a kind of good seal performance, transportation, easy for installation
integrated chilling water seal and the seal arrangement of mechanical seal device.
The present invention
the mechanical seal device of integrated water seal includes mechanical seal device, water seal arrangement and gland and forms, and mechanical seal device is by stationary ring 1, stationary ring auxiliary seal ring 10, stationary ring locating stud 11, by rotating ring 3, moving ring assembly, axle sleeve 4 that rotating ring slippage seal ring 30, rotating seat 31, spring seat 32, rotating ring counterbalance spring 33, driving pin 34 form, axle sleeve 4 auxiliary seal rings 40, axle sleeve 4 fixedly Cock screw 41 form, moving ring assembly is arranged on axle sleeve 4
stationary ring 1 is arranged on the inner stopping table of gland 2; Water seal arrangement is by static friction ring 5, static friction ring slippage seal ring 50,
static friction ring counterbalance spring 51, kinetic friction ring 6, kinetic friction ring auxiliary seal ring 60,
kinetic friction ring location snap ring 62, limited location snap ring 7 forms,
the static friction ring 5 of water seal arrangement is arranged on the outer end stopping table of gland 2, and kinetic friction ring 6 passes throughcock screw 41 is fixedly connected with axle sleeve 4 outer ends, and Cock screw 41 is fixedly connected axle sleeve 4 and axle simultaneously, on axle sleeve 4, arranges
kinetic friction ring location snap ring 62 with
axially locating is carried out in the 6 outboard ends cooperations of kinetic friction ring, and static friction ring 5 coordinates with kinetic friction ring 6 under the effect of its counterbalance spring 51, forms the water seal arrangement of Mechanical Sealed Type, offers boss snap ring 61 on the outer shroud of kinetic friction ring 6,on limited location snap ring 7, offer draw-in groove 70 with
snap ring 61 coordinates, limited location snap ring 7 is fixed on gland 2 by its front end screw rod, like this will
mechanical seal device, water seal arrangement, axle sleeve, gland collection dress are fixed together.
the water seal arrangement good airproof performance of Mechanical Sealed Type of the present invention, bearing capacity is high, and zero leakage is guaranteed to make the sealing of water sealchilled water (chw) can recycle
,prevent that chilled water (chw) from directly discharging and leaking the waste that causes water resources.
water seal arrangement, together with mechanical seal device, axle sleeve 4, gland 2 integrated installations, forms whole auxiliary type device, and transportation is installed, easy to use.And water seal arrangement bearing capacity is high, chilling pressure improves, and can reduce the pressure reduction of its anterior mechanical seal device, improves the running environment of mechanical seal device, improves reliability and the working life of mechanical seal device.
