Description
Technical field
The utility model relates to water-treatment technology fields more particularly to a kind of vacuum in recirculating cooling water system to draw
Water module.
Background technique
In the circulation of open type, through cooling tower water after cooling, meeting gravity is flow in storage cistern.Cooling water pump
Cooling water is delivered to and needs cooling to use water spot.At equipment, heat exchange is completed, equipment is cooled down, the temperature liter of water
Height, and be back in storage cistern.During circulation, due to equipment, the infiltration of pipeline, wind, evaporation and to guarantee water quality
And the blowdown etc. carried out, a part of water can be lost.To guarantee liquid level certain in storage cistern, need to be continuously replenished a part of fresh
Water.
For such system, if the mounting height of the cooling water pump used is more than the normal liquid level in pond, for
Common centrifugal pump should all pour water in advance every time before starting.In order to guarantee the normal operation of system, the type selecting of cooling water pump and
The design of pipeline usually has three ways, such as following: self priming pump；Non self-priming pump (Ordinary Centrifugal Pumps)+bottom valve；Non self-priming pump (commonly from
Heart pump)+vacuum diversion volume.
So-called self priming pump is exactly installing after starting is poured water for the first time, behind shut down when restarting, do not need again
It pours water, by the operating of short time, by pumping itself effect, so that it may water be drunk up, investment works normally, but same water
The price of self priming pump be higher by much than Ordinary Centrifugal Pumps.
For investment reduction, Ordinary Centrifugal Pumps can be selected, and trying to make can water in pump chamber.In engineering, it will usually
Use bottom valve or the matched use of drainage tank.Bottom valve is mounted on the import of suction hose, but larger in pump operation, especially water
When, bottom valve will cause very big hydraulic loss, and a large amount of engineering practices show that bottom valve is easy to leak, and effect is simultaneously unstable
Reliably.So vacuum diversion volume is because its equipment is simple, low cost is easy to operate, and the advantages such as easy to maintain have obtained widely answering
With, and application range is also constantly being widened, and application in practice is also ceaselessly perfect.But it is used for recirculating cooling water system
In, continually and steadily run it is critically important, if may be damaged because temperature is excessively high because equipment cannot be cooled down in time.Institute
With other than the requirement to pump is high, the requirement to the reliability and stability of priming device is very high.
Theoretically if the liquid level in pond is kept constant in drainage tank, and pipe-line system is tight, in system-down
Afterwards, the liquid level in drainage tank can return to the height of design always.But in practical engineering applications, the liquid level in pond will not be constant
It is constant.When the liquid level decline in pond, the liquid level in drainage tank also can be with reduction, when being reduced to certain height, just not
It is able to satisfy the water suction requirement of pump, water suction does not come up, and needs moisturizing.
Or in the system for having several pumps in parallel, the switchover operation of pump makes the air in pipeline enter drainage tank
In, the vacuum degree of drainage tank is destroyed, moisturizing again is needed.Just needs are manually opened again at this time is mounted on the manual of top of the tank
Water compensating valve and exhaust valve carry out moisturizing, after turn off valve after the completion of manual moisturizing.
The shortcomings that remaining the following aspects in the prior art:
1, on startup, the vacuum degree in drainage tank is inadequate for system after each shut down, and when needing moisturizing, requires artificial
Remove opening and closing valve；
2, these usual water inlet water compensating valves and exhaust valve are all located at the top of jar again, cumbersome and inconvenient；
3, the case where can not judging liquid level in tank body from the outside of drainage tank, can not understand the vacuum degree of tank interior in time
Whether destroyed, can not timely termination of pumping, prevent pump idle running；
4, when there are more water pumps in parallel or having stand-by pump, when water pump automatically switches, enter drainage tank if any air,
It is difficult to find in time, if dallied for a long time, biggish damage is had to water pump；
5, in recirculating cooling water system, if priming device is unable to continuous service, equipment may be made because cannot get
It cools down and damages in time and effectively.
In view of the above shortcomings, the designer is actively subject to research and innovation, it is a kind of for recirculated cooling water to found
Vacuum water diversion module in system makes it with more the utility value in industry.
