Abstract
The invention discloses a self-pressure boosting system for a double-end mechanical seal. The self-pressure boosting system comprises a mechanical seal device, a balancing tank and a reaction tank, wherein the upper part of the balancing tank is connected with a sealing liquid inlet of a sealing cavity of the mechanical seal device through a pipeline, and the lower part of the balancing tank is connected with an in-kettle gas communication pipe of the reaction kettle through a pipeline; a piston and a piston rod are arranged in the balancing tank and are matched with each other; the piston is sealed with the cylinder wall of the balancing tank through an O-shaped seal ring; the piston rod slides along the axial direction; a spring is arranged on the piston rod. The self-pressure boosting system is simple in structure; the upper part of the balancing tank is connected with the sealing cavity through the pipeline, and the lower part of the balancing tank is communicated with the reaction kettle through the pipeline, so that the pressure in the kettle is transferred to the sealing cavity through the piston in the balancing tank; the self-pressure boosting system is suitable for occasions where mediums in the kettle cannot be mixed with sealing liquid.
Description
Technical field
The present invention relates to field of sealing technology, particularly relate to a kind of double mechanical seal pressure itself pressure charging system.
Background technology
Leakage problem ubiquity in modern industry, reveals and not only can cause energy waste, material loss, environmental pollution, even also can lead to fire, set off an explosion, directly jeopardize personal safety, bring huge economic loss.For the occasion that medium in still can not mix mutually with sealing liquid, if seal bad, then may have burn into inflammable, explosive, poisonous danger.
Summary of the invention
The present invention, in order to overcome the deficiency of above-mentioned technical problem, provides a kind of double mechanical seal pressure itself pressure charging system, is applicable to the occasion that in still, medium can not mix mutually with sealing liquid.
The technical scheme solved the problems of the technologies described above is as follows:
A kind of double mechanical seal pressure itself pressure charging system, comprise mechanically-sealing apparatus, compensator and reactor, the top of described compensator is connected with the sealing liquid import of the annular seal space of mechanically-sealing apparatus by pipeline, bottom by pipeline be connected the gas reactor communicating pipe of reactor, piston and piston rod is provided with in described compensator, described piston and piston rod coordinate, described piston adopts O shape circle to seal with the casing wall of compensator, described piston rod axially slides, described piston rod is provided with spring, sealing liquid is walked in the pipeline on described compensator top, gas medium is walked in the pipeline of bottom.
The seal chamber of described mechanically-sealing apparatus is provided with chuck coolant outlet and chuck cooling water inlet.
The pipeline of connection compensator and mechanically-sealing apparatus and reactor is provided with Pressure gauge.
Also comprise sealing liquid supplementary device, described sealing liquid supplementary device supplements pipeline by hydraulic pump and sealing liquid and forms, and sealing liquid supplements pipeline one end and is connected with hydraulic pump, and the other end supplements mouth with the sealing liquid on the seal chamber being arranged on mechanically-sealing apparatus and is connected.
Structure of the present invention is simple, and compensator top is connected with annular seal space pipeline, and bottom pipeline is communicated with reactor, makes the pressure in still be delivered to annular seal space by dummy piston.Because the bearing area of piston upper end to decrease the area of a piston rod than piston bearing area, therefore sealing liquid pressure increases by two ends bearing area inverse proportion, thus ensure that good air-proof condition.Piston O shape circle seals with casing wall, and can slide axially.Piston can transmission of pressure, can play again the buffer action of sealing liquid and gas reactor.Be provided with spring on the piston rod, regulate amount of spring compression, make spring tension just in time offset the frictional force of piston upper O-shape ring to casing wall, to reduce the error between pressure differential calculated value and actual value.In addition, the lifting of piston rod also has the effect of liquid level in instruction compensator.When needing supplementary after sealing liquid is revealed, annotate with manual pump.
