Description

A kind of pump seal water conservation device

Technical field

The utility model relates to water circulating technology field more particularly to a kind of pump seal water conservation devices.

Background technique

During water pump operation, mechanical seal dynamic and static ring can generate a large amount of heat due to running at high speed, using close Water shutoff is cooled down and is lubricated to dynamic and static ring, is on the one hand prevented pumping material from entering mechanical seal cavity, is on the other hand sealed Water forms water membrane between dynamic and static ring, reaches certain lubricant effect.However in practical applications, due to the sealing water of pump The problems such as connection size is smaller, frequent occurrence sealing water insufficient pressure, line clogging causes water pump sealing water insufficient, such as The case where fruit will cause the damage of mechanical seal high temperature without discovery in time.

Utility model content

In view of this, the sealing water sustainable supply that can ensure to pump the utility model proposes one kind, prevents mechanical close Seal the pump seal water conservation device of damage.

The technical solution of the utility model is achieved in that the utility model provides a kind of pump seal water conservation dress It sets, including technique pump, water-sealed pump and sealing water pot, further includes direct-operated regulator and filter, the technique pump, self-operated type Regulating valve, filter, water-sealed pump and sealing water pot are sequentially communicated and form closed circuit circulatory system.

On the basis of above technical scheme, it is preferred that it further include flow instruction switch, the flow instruction switch connection In the closed circuit circulatory system, the flow instruction switch is electrically connected with technique pump.

On the basis of above technical scheme, it is preferred that the flow instruction switch is warming type flow switch or miniature Flowmeter.

On the basis of above technical scheme, it is preferred that the filter is y-type filter or T-type filter or basket Filter.

The utility model has the advantages that compared with the existing technology

The utility model is miscellaneous to what is be likely to occur in circulation line by the way that filter is arranged on the circulation line of sealing water Matter, which is filtered, avoids the sealing water interface pumped to technique from resulting in blockage, and secondly the adjustable technique pump of direct-operated regulator is close Water shutoff intake pressure, it is ensured that the pressure balance of technique pump mechanical sealing, the flow of flow instruction switch real time monitoring sealing water are kept away To exempt to occur stopping to lead to technique pump overheat, the utility model can pump technique and play a good protective effect, and structure is simple, and It can be realized the protection automated to a certain degree.

Detailed description of the invention

In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor Under, it is also possible to obtain other drawings based on these drawings.

Fig. 1 is the structural schematic diagram of the pump seal water conservation device of the utility model.

In figure: 1- seals water pot, 2- water-sealed pump, 3- filter, 4- direct-operated regulator, 5- flow instruction switch, 6- Technique pump.

Specific embodiment

Below in conjunction with the utility model embodiment, the technical solution in the utility model embodiment is carried out clear Chu is fully described by, it is clear that and described embodiment is only a part of embodiment of the utility model, rather than all Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making creative work Under the premise of every other embodiment obtained, fall within the protection scope of the utility model.

As shown in Figure 1, a kind of pump seal water conservation device of the utility model comprising technique pump 6, water-sealed pump 2, close Water shutoff tank 1, direct-operated regulator 4, filter 3 and flow indicate switch 5, wherein technique pump 6, water-sealed pump 2, seal water pot 1, Direct-operated regulator 4, filter 3 and flow instruction switch 5 are sequentially communicated and form closed circuit circulatory system, it should be appreciated that It is above-mentioned to be sequentially communicated the sequence for being not intended to limit and being connected between each other.

Sealing water circulates in the circulatory system, and setting filter 3 can remove the mechanical admixture in sealing water It removes, reduces the risk of the sealing water line clogging of technique pump 6；The adjustable technique of direct-operated regulator 4 is set and pumps 6 sealing waters Intake pressure, it is ensured that 6 mechanical seal pressure at two ends of technique pump is balanced, avoids the pumping pressure of water-sealed pump 2 excessive；Flow instruction Switch 5 can pump the water inlet of 6 sealing waters to technique and monitor in real time, it is ensured that the circulation of sealing water is normal, and protection technique pump 6 is mechanical close The effect of envelope.

In a specific embodiment, filter 3 is Y-type pipe filter 3.

In a specific embodiment, filter 3 is T-type piping filter 3.

In a specific embodiment, filter 3 is basket filter 3.

In a specific embodiment, flow instruction switch 5 is warming type flow switch.

In a specific embodiment, flow instruction switch 5 is micro flowmeter.

In a specific embodiment, flow instruction switch 5 and technique pump 6 are electrically connected, when flow instruction switch 5 detects When flow is relatively low in closed circuit circulatory system or does not have flow, flow instruction switch 5 transmits corresponding electric signal to technique pump 6 and controls Technique pump 6 processed is out of service, avoids technique from pumping 6 temperature excessively high.

The working principle of the pump seal water conservation device of the utility model are as follows:

Water-sealed pump 2 carries out pumping circulation for the water in water pot 1 is sealed, and sealing water flows in the circulatory system, passed through When filter 3, filter 3 is filtered the mechanicalness impurity in sealing water, filters the sealing water finished and enters self-supporting adjusting The hydraulic pressure of the sealing water in the circulatory system is adjusted in valve, direct-operated regulator 4, avoids the hydraulic pressure of recirculated water excessive to machinery Sealing causes to damage, and sealing water again passes by flow instruction switch 5, and flow indicates that switch 5 detects the flow of sealing water, if sealing Water flow is abnormal, and flow instruction 5 one side of switch sounds an alarm, and system operator is broken down, and on the other hand directly sends out Electric signals keep technique pump 6 out of service to technique pump 6, and if normal, sealing water enters circulation temperature lowering in technique pump 6, finally Again flow into sealing water pot 1.

The foregoing is merely the better embodiments of the utility model, are not intended to limit the utility model, it is all Within the spirit and principles of the utility model, it is practical new to should be included in this for any modification, equivalent replacement, improvement and so on Within the protection scope of type.
