Description
Technical field
The utility model belongs to field of chemical equipment, and in particular to a kind of cooling device of mechanical seal.
Background technique
In chemical industry, mechanical seal for pump (abbreviation machine envelope) is widely used, but in use process, since machine seals
Rotating ring and stationary ring phase mutual friction, a large amount of heat can be generated, if cooling not in time, it is easy to cause machine envelope be burned out, for solution
Certainly this problem, typically now using installation temperature lowering water pipeline, make cooling water flow through machine be honored as a queen discharge mode carry out it is mechanical close
The cooling of envelope prevents from burning machine envelope.But the hydraulic pressure that this mode seals inflow machine has particular requirement, and hydraulic pressure cannot be excessive, not so
It is easily damaged machine envelope；Simultaneously in some enterprises, circulating water quality difference just have trash flow enter machine envelope result in blockage, influence machine envelope
Normal use, reduce production efficiency；Or management defect causes arbitrarily to stop recirculated water, to machine Feng Jiangwen or can not just stop
It produces or machine is sealed after burning and stopped production, cause serious consequence；In addition, cannot be recycled after the envelope outflow of cooling water slave, cause
The waste of water resource.
Summary of the invention
Technical problem to be solved by the utility model is: overcoming the deficiencies of the prior art and provide a kind of drop of mechanical seal
Warm device, energy automatic circulation water-supplying is given mechanical seal for pump to cool down, is not limited by water supply, and saves water resource.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of cooling device of mechanical seal, packet
Include pump machine envelope, machine envelope water inlet pipe and machine envelope return pipe, it is characterised in that: further include water tank, machine seals water inlet pipe and machine Feng Huishui
Pipe is respectively communicated with machine envelope and water tank, and machine seals position and is lower than water tank.
It preferably, further include tank inlet pipe, tank inlet pipe is passed through in water tank, and tank lid is arranged on water tank.
Preferably, ball-cock assembly is set on the tank inlet pipe in water tank.
Preferably, blowdown valve is arranged in water tank bottom.
Preferably, machine envelope water inlet pipe and machine envelope outlet pipe use transparent hose.
Compared with prior art, the utility model has the beneficial effects that
1. machine envelope water inlet pipe and machine envelope return pipe are respectively communicated with water tank and machine envelope, it is high lower than liquid level in water tank that machine seals position
Degree, therefore cooling water can penetrate through water tank and machine envelope water inlet pipe, due to the relative friction of rotating ring and stationary ring in machine envelope use process
Heat can be generated, is heated up when water flows there through, due to the particular community of the water temperature temperature difference, the high water of temperature is rotated dynamic
Ring carries rotation slave envelope return pipe outflow again, and the low water of temperature flows into machine envelope again, faint water circulation is formed, to guarantee temperature
The continual inflow machine envelope of low water is spent, realizes the effective temperature-reducing of machine envelope, prevents machine envelope damage.
2. as long as no longer needing to be passed through a large amount of water, to be greatly saved guarantee that the liquid level in water tank meets setting value
Water resource.
3. ball-cock assembly is arranged on the tank inlet pipe in water tank, water inlet can be automatically controlled when liquid level is too low, whole process without
Manual operation control is needed, human cost is greatlyd save.
4. water tank with cover is arranged, the water level checked in water tank, water quality situation can be opened at any time, can also prevent dust impurity
It falls into water tank, keeps the cooling water clean hygiene in water tank.
Detailed description of the invention
Attached drawing 1 is the utility model structure diagram；
Attached drawing 2 be pump with machine seal in liquid communication schematic diagram.
In the figure, it is marked as
1 tank lid；2 water tanks；3 ball-cock assemblys；4 machines envelope；5 tank inlet pipes；6 machines seal water inlet pipe；7 machines seal return pipe；8 blowdowns

Specific embodiment
Embodiment with reference to the accompanying drawing is described further the utility model: a kind of cooling device of mechanical seal, packet
Mechanical seal for pump (abbreviation machine envelope) 4, machine envelope water inlet pipe 6 and machine envelope return pipe 7 are included, further includes water tank 2, machine seals 6 He of water inlet pipe
Machine envelope return pipe 7 is respectively communicated with machine envelope 4 and water tank 2, and cooling water is held in water tank 2, and machine seals 4 positions lower than water tank 2 or is lower than
Liquid level in water tank 2 guarantees that water can seal water inlet pipe 6 by machine out of water tank 2 and flow into machine envelope 4.Machine seals water inlet pipe 6 and machine
It seals return pipe 7 and uses transparent hose, conveniently check the quality of the water of inflow machine envelope 4, it is problematic to find in time.2 top of water tank
Ball-cock assembly 3 is arranged on the tank inlet pipe 5 in water tank 2 in joining water box water inlet pipe 5, and ball-cock assembly 3 is able to maintain the liquid level in water tank 2
Within the scope of certain height.Tank lid 1 is also set up on water tank 2, the water level height and water quality feelings for facilitating worker to check in water tank 2
Condition.Waste water can be discharged by blowdown valve 8 when needing replacing the water in water tank 2 for 2 bottom of water tank setting blowdown valve 8, be replaced
Clean cooling water.
Utility model works principle and the course of work are as follows:
If Fig. 1 gets up water tank 2, machine envelope water inlet pipe 6,4 connection of machine envelope, ball-cock assembly 3 is opened, and is flowed into water tank 2 enough
Cooling water, lower than the liquid level in water tank 2, cooling water penetrates through machine envelope 4 by machine envelope water inlet pipe 6 for the position of machine envelope 4, and machine is sealed 4
Machine envelope return pipe 7 is connected to after interior air discharge again, in water flow recovery tank 2.As shown in Fig. 2, when machine 4 work of envelope, 11 He of rotating ring
Friction generates heat for stationary ring 12, and neighbouring coolant-temperature gage increases, and due to the particular community of the water temperature temperature difference, temperature is higher, the movement of water
Viscosity is smaller, therefore the high water of temperature can rotate slave envelope return pipe 7 with the carrying of phantom ring 11 and flow back into water tank 2, and temperature is low
Water again by machine envelope water inlet pipe 6 flow into machine envelope 4, faint natural water circulation is formed, to guarantee that the low water of temperature is continual
Inflow machine envelope 4 realizes the effective temperature-reducing of machine envelope 4, prevents 4 damage of machine envelope.This process is not necessarily to manual intervention, automatically keeps machine envelope
4 cooling effectively carries out, and prevents 4 damage of machine envelope.When the liquid level in water tank 2 is too low, ball-cock assembly 3 is opened, clean water
Water tank 2 is flowed into from tank inlet pipe 5, the liquid level in water tank 2 is kept to be in certain height always.When impurity is too many in water tank 2,
Blowdown valve 8 can be opened, the sewage in water tank 2 is discharged, opened ball-cock assembly 3, replace clean cooling water.
The above descriptions are merely preferred embodiments of the present invention, is not to make other forms to the utility model
Limitation, any person skilled in the art is changed or is modified as possibly also with the technology contents of the disclosure above equivalent
The equivalent embodiment of variation.But it is all without departing from the content of the technical scheme of the utility model, the technology according to the utility model is real
