Abstract
The utility model relates to a compact overall-external assembling packaging type mechanical seal for a pump. The mechanical seal comprises a movable seal ring, a static seal ring, a spring-loading device, secondary seal components and a gland, wherein the movable seal ring, the static seal ring, the spring-loading device and the secondary seal components are all placed in the gland, equal to or lower than the gland and is near a fluid end surface. The compact overall-external assembling packaging type mechanical seal for the pump is characterized by convenient and fast seal replacement and good sealing effect.
Description
Technical field
The utility model relates to mechanical seal for pump field, refers in particular to the complete exterior unit loading type mechanical seal for pump of a kind of compact type.
Background technique
Mechanical seal is a kind of oil-sealing arrangement of rotating machinery.Such as equipment such as centrifugal pump, centrifuge, reactor and compressors.Because transmission shaft is applied in inside and outside equipment, like this, between axle and equipment, there is a circumferential clearance, medium in equipment passes through this gap to outward leakage, if equipment internal pressure is lower than barometric pressure, air is revealed in equipment, therefore must have one to stop the gland seal device of revealing.The kind of shaft seal is a lot, because having few and life-span of leakage rate, mechanical seal the advantage such as grows, so mechanical seal is in the topmost shaft sealing mode of these equipment in the world today, end face seal is named again in mechanical seal, and the shaft seal case of past splendid attire mechanical seal is the stuffing box designing for soft packing seal.It is not suitable for splendid attire mechanical seal, and not only size is too little, gap is too narrow, and simple drum is also improper.
-as mechanical seal Shi Xu Cheongju is installed on the axle of fluid machinery washes, measure, then part of a part is installed, is adjusted, and works loaded down with trivial details, the amount of labour is large.
Utilize " shipping container " concept in transportation, produced cartridge seal.The rotation of this sealing and stationary part are pre-installed in aggregates before installation, are sleeved on after qualified with pressure testing on inspection in shaft seal case on axle, with Cock screw, are fixed on axle, tighten gland bolt, remove collection and set bit slice, mechanical seal just can, in parallel surface working state, be put into operation.So not only easily assemble but also guarantee assembly quality.Welded metal-bellows mechanical seal is all made cartridge seal at present, just has above-mentioned advantage.Cassette sealing is also a kind of integrated mechanical sealing.The stationary ring of this sealing, rotating ring, axle sleeve and gland and auxiliary seal all collect and are fitted together with an axle sleeve before installation, are convenient to check assembly quality.After passed examination, need only closely capping, clamp-screw.The black box of so prior assembling, inspection and test, easily guarantees to install and assembly quality.But existing cartridge seal, does not also really accomplish entirely exteriorly, and volume is larger, compact not.
Model utility content
The purpose of this utility model is to overcome above-mentioned deficiency, for making mechanical seal for pump sealing change convenient and swift design.
The object that the utility model is is achieved in that
The complete exterior unit loading type mechanical seal for pump of a kind of compact type, comprise rotary packing ring, stationary seal ring, spring loaded mechanism, secondary seal element, gland, described rotary packing ring, stationary seal ring, spring loaded mechanism, secondary seal element are all built in gland, put down in or recessed in the nearly fluid end face of gland.
Preferred scheme, the radial cavity footpath of described gland internal flow is greater than the radial cavity footpath of equipment Seal cage.
Preferred scheme, described spring loaded mechanism is parallel with seal ring, and spring and seal ring transmit spring pressure by a bending ring.
Preferred scheme, described axle sleeve and mechanical seal collection are fitted together.
Preferred scheme, described gland is also provided with at least one flushing hole.
Preferred scheme, described flushing hole end is provided with porous and divides water ring.
The beneficial effects of the utility model: change the faster convenience of sealing, sealing effect is better.
