Background technology
Heart of the pump as technological process plays a part of the various fluids of conveying.The medium type of pump conveying is various,
Chemical property is different.When conveying inflammable and explosive, poisonous and hazardous medium, pump is often using series connection or Double End machine
Envelope to prevent medium from revealing to atmospheric side avoids that accident, environmental protection occurs.Realize that above functions needs to add for mechanical seal
Fill set of system.System provides sealing liquid, is recycled between secondary seal, and the pressure of sealing liquid is higher than pressure medium, plays barrier and is situated between
The effect of matter.
Existing system is pressurizeed for system by ambient pressure source, when pressure source interrupts, since machine is sealed by back-pressure, is made
It is opened at end face, machine envelope leakage.To improve the security reliability of system, system is changed to included pressure by us by external pressure source
Source.
Utility model content
In order to solve the above-mentioned technical problem, it the utility model discloses a kind of sealing liquid device for mechanical seal, provides
A kind of sealing liquid pressurization not depending on external pressure source between two-stage sealing, the sealing liquid device for preventing medium from being revealed to atmospheric side.
Specific technical solution is as follows：
A kind of sealing liquid device for mechanical seal, including holder, liquid storage device, bladder type hydropneumatic accumulator and manual fluid infusion pump；Institute
Holder side installation fluid reservoir is stated, circulation fluid inlet attack is housed in fluid reservoir upper left-hand, is equipped in fluid reservoir upper right
Circulation fluid outlet connection connects metal temperature table, and circulation fluid inlet attack is arranged in fluid reservoir side, and the other side is provided with circulation fluid
Outlet connection, fluid reservoir top are switched equipped with pressure gauge and pressure warning unit；Bladder type hydropneumatic accumulator is fixed in the holder other side,
Bladder type hydropneumatic accumulator is connect with fluid reservoir, is pumped equipped with manual fluid infusion on holder, the manual fluid infusion pump connection gas cylinder, and by high pressure
Hose connects fluid reservoir.
The bladder type hydropneumatic accumulator, manual fluid infusion pump, fluid reservoir are fixed on its position height relationship on holder by pipe collar
It is flat in fluid reservoir bottom end that it is followed successively by fluid reservoir, bladder type hydropneumatic accumulator and manual fluid infusion pump, the bladder type hydropneumatic accumulator position from high to low
Face is hereinafter, the manual fluid infusion pumps position below the plane of bladder type hydropneumatic accumulator bottom end.
Compared with prior art, the utility model has the advantages that：
It is the sealing liquid pressurization between two-stage sealing that the utility model, which does not depend on external pressure source, and medium is prevented to be revealed to atmospheric side
Sealing liquid device.The pressure that sealing liquid is provided by bladder type hydropneumatic accumulator is higher than pressure medium 0.2-0.3MPa, independent of external environment,
It, can be by gas cylinder tonifying Qi, easily when gas consumption inside bladder type hydropneumatic accumulator.Therefore, the reliability of device in the running
Increase, avoids the unexpected of external pressure source from interrupting the damage leakage for causing sealing, improve the service life of sealing, reduce pump and stop
Machine causes damages to production and hidden danger.
Bladder type hydropneumatic accumulator, manual fluid infusion pump, fluid reservoir are fixed on holder its position height relationship by height by pipe collar
It is followed successively by fluid reservoir, bladder type hydropneumatic accumulator and manual fluid infusion pump to low, bladder type hydropneumatic accumulator position is in fluid reservoir bottom end plane hereinafter, hand
Dynamic fluid infusion pumps position in bladder type hydropneumatic accumulator bottom end plane hereinafter, the drop of height can bring impact bottom hydrops while fluid infusion
Effect, play the role of stirring.
