Description
Technical field
The utility model is related to the cooling structure on a kind of vacuum equipment more particularly to a kind of mechanical seal of vacuum pump are cold
But structure.
Background technology
Since there is pressure differences between fluid in pump and the outer air of pump, slurry leaks in order to prevent, therefore pump needs at runtime
If sealing device is called axle envelope.Common axle envelope type has：Packing seal, mechanical seal, dynamic seal and floating seal
Etc. forms.In terms of current every profession and trade pump situation, mechanical seal has become the general seal form of every profession and trade, and the sealing
Form operates steadily, and reliably, very big economic benefit is brought to every profession and trade.
The cooling of the outer mechanical seal of vacuum pump is originally to be sealed up by lubricating oil splash in oil pocket to machine, is taken away by lubricating oil
Heat.Such cooling is directly too many by uncontrollable factor, be easy to cause because cooling oil temperature is excessively high or other aspects problem shadow
It rings and machine envelope is caused to burn.
Invention content
The purpose of this utility model is to overcome above-mentioned deficiency provides a kind of mechanical seal cooling structure of vacuum pump, leads to
Supercooled water carries out cooling heat dissipation to mechanical seal structure, prevents machine envelope from being burnt due to high oil temperature.
What the purpose of this utility model was realized in：A kind of mechanical seal cooling structure of vacuum pump, it includes installation
End cap in pump housing one end is provided with metal flange on the end cap, and main shaft installation is offered on the metal flange
Hole, mechanical seal structure are set in spindle mounting hole, and one is offered on the metal flange on the outside of the spindle mounting hole
Circle is provided with cooling water inlet pipe on the outer edge surface of the metal flange and cooling water goes out around the bosh of mounting hole
Water pipe, the cooling water inlet pipe and cooling water outlet pipe connect respectively with the both ends of bosh.
Compared with prior art, the beneficial effects of the utility model are：
The utility model is after structure is changed, and machine envelope can be immersed in lubricating oil, and excessive heat passes through metal on pump cover
Wall is transmitted in screw clamp cooling water, is led out by water cycle, and the machine of reduction seals the probability burnt caused by due to high temperature.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the sectional view of the utility model.
Wherein：
End cap 1
Metal flange 2
Spindle mounting hole 3
Bosh 4
Cooling water inlet pipe 5
Cooling water outlet pipe 6.
Specific embodiment
Referring to Fig. 1-Fig. 2, the utility model is related to a kind of mechanical seal cooling structure of vacuum pump, including being mounted on pump
The end cap 1 of body one end is provided with metal flange 2 on the end cap 1, and main shaft installation is offered on the metal flange 2
Hole 3, mechanical seal structure are set in spindle mounting hole 3, are opened up on the metal flange 2 in 3 outside of spindle mounting hole
The bosh 4 for having a circle to surround mounting hole, is provided with 5 He of cooling water inlet pipe on the outer edge surface of the metal flange 2
Cooling water outlet pipe 6, the both ends of the cooling water inlet pipe 5 and cooling water outlet pipe 6 respectively with bosh 4 connect, cooling
Water is passed into bosh by water inlet pipe, and the heat that machine envelope generates takes on metal flange 2 under the action of lubricating oil, leads to
Heat exchange to cooling water, after cooling water temperature raising by cooling water outlet is discharged, is recycled by water by heat by heat transfer
It leads out, the machine of reduction seals the probability burnt caused by due to high temperature.
