Description
Technical field
Single-stage cantilever formula slurry pump technical field, more particularly to Pulp pump technical field of sealing technology are the utility model is related to, is had
Body has cooling and the Mechanical Sealed Type Pulp pump of warning function to be a kind of.
Background technology
Packing seal also known as compresses sealing, and after filler loads pan feeding chamber, it is compressed axially through gland screw, when
When axle has relative motion with filler, because the plasticity of filler makes it produce radial load, and it is in close contact with axle, while soaked in filler
The lubricant of stain is extruded, and oil film is formed between contact surface.Because contact condition is not that especially uniformly, contact site occurs
" boundary lubrication " state, it is referred to as " bearing effect "；And not in contact with recess form small oil groove, its prevent liquid stream reveal effect,
Referred to as " labyrinth effect "." bearing effect " and " labyrinth effect " maintains the excellent sealing state of packing seal jointly.
However, the fluid media (medium) of single-stage cantilever formula Pulp pump conveying contains suspended solids, if being used in work condition environment
The sealing means of packing seal, once solid particulate matter enters in packing cavity, not only by " the bearing effect of heavy damage packing seal
Should " and " labyrinth effect ", and causing the parts wears such as axle, gland and filler to be accelerated, packing seal will gradually lose densification
Performance and cause seepage and seal failure.
Compared to packing seal, mechanical seal is by a pair or several end faces to making relative lubrication perpendicular to axle are in fluid
The elastic force of pressure and compensation mechanism（Or magnetic force）Remained engaged with effect and be equipped with auxiliary seal and reach the axle envelope of prevention leakage
Device, and disclosure satisfy that working condition seal request of the pumped (conveying) medium containing solid particle.And the rotating ring and stationary ring of mechanical seal
Between seal face between need to maintain one layer of very thin liquid film to can be only achieved the effect of sealing.Therefore single-stage cantilever formula Pulp pump
The medium of conveying is the fluid containing solid suspension, according to mechanical seal mode, should ensure that mechanical seal intracavitary is deposited all the time
Playing the cooling water of lubrication.
The content of the invention
The purpose of this utility model is the provision of a kind of Mechanical Sealed Type Pulp pump with cooling and warning function, with
Mechanical sealing assembly self-lubricating is realized, from the function such as cooling and automatic alarm, so as to improve the use of slurry pump mechanical sealing
Life-span.
To solve problem above, the utility model is achieved through the following technical solutions：
A kind of described Mechanical Sealed Type Pulp pump with cooling and warning function, including Pulp pump main shaft, machinery are close
Sealing assembly, cooling water pipe cooling water tank, alarm controller and leve monitor, wherein mechanical sealing assembly are installed on Pulp pump master
On axle, two cooling water pipes are drawn from cooling water tank bottom respectively, the other end cooling water with mechanical sealing assembly both sides respectively
Inlet opening is connected, and alarm controller and leve monitor collectively form level monitoring warning system, level monitoring warning system
It is installed in cooling water tank, the water level of cooling water in cooling water tank is monitored and alarmed in real time.
Described level monitoring warning system, leve monitor are fixed on cooling water tank inwall correct position, controlling alarm
Device is fixed on cooling water tank outer wall correct position, and is connected with leve monitor, when the chilled water in cooling water tank declines
During to leve monitor position, alarm controller will start.
A kind of described Mechanical Sealed Type Pulp pump with cooling and warning function, its operation principle are as follows：Work as slurry
When pump is run in normal conditions, the cooling water in cooling water tank enters through cooling water pipe in the annular seal space of mechanical sealing assembly,
Ensure that the abrasive end face between the rotating ring and stationary ring of mechanical seal forms moisture film；The cooling water and seal face of mechanical seal intracavitary
After carrying out certain heat exchange, cooling water takes away heat caused by mechanical seal, and mechanical sealing assembly is carried out to a certain degree
Cooling；When the cooling water water level in cooling water tank is reduced to leve monitor position, alarm controller will start, and prompting should
Timely termination of pumping or filling cooling water.
The beneficial effects of the utility model are as follows：
（1）Cooling water in cooling water tank flows to mechanical sealing assembly by cooling water pipe, is formed in mechanical seal chamber
One layer of liquid film, it disclosure satisfy that containing the harsh seal request of the working conditions such as solid particle medium.
（2）Level monitoring warning system is by realizing mechanical sealing assembly self-lubricating to the variation monitoring of liquid level, cooling down certainly
The function of automatic alarm, so as to improve the service life of slurry pump mechanical sealing.
