Abstract
The invention discloses an anti-self-sucking pump evacuator. The anti-self-sucking pump evacuator is arranged between a liquid storage tank and a self-sucking pump and comprises an airtight balancing tank. The airtight balancing tank is provided with a balancing tank liquid outlet connected to a liquid inlet of the self-sucking pump, and is further provided with a balancing tank liquid inlet connected to the liquid storage tank, and the airtight balancing tank is filled with liquid. When the self-sucking pump is started, a pump body can be quickly filled with the liquid, the airtight balancing tank is in a micro negative pressure state due to reduction of the liquid in the airtight balancing tank, and then liquid materials of the liquid storage tank installed below the ground are pumped up to be continuously input into the pump body, so generation of evacuation of the pump body is avoided, and safe operation of the anti-self-sucking pump evacuator is guaranteed.
Description
Technical field
The present invention relates to the device that a kind of anti-self-priming pump is found time.
Background technique
In chemical industry, due to need of production, there are a lot of liquid containers need to be installed to below ground, the liquid material of liquid container the inside is all generally to shift conveying by self-priming pump, it is all that a very long craspedodrome pipeline is by being directly connected to self-priming pump in geosyncline that the pipeline of traditional underground storage self-priming pump is installed, after self-priming pump starts, impeller High Rotation Speed makes the current direction volute in impeller conduit, make into interruption-forming vacuum, thereby the liquid of below ground is attracted up, and then be conveyed into manufacturing mechanism.
But in actual production process, particularly for the larger liquid material of some density as concentrated sulphuric scid etc., due to density, to add more greatly suction pipeline long, the attraction force utmost point that now only relies on self-priming pump self to produce is not easy at short notice the liquid material in geosyncline to be attracted up, thereby cause the vaccuum phenomenon of the pump housing, be easy to cause the pump housing to damage, both delayed production, increased again cost.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind ofly can effectively avoid the pump housing to occur vaccuum phenomenon, the anti-self-priming pump evacuator of avoiding the pump housing to damage.
For solving the problems of the technologies described above, technological scheme of the present invention is: anti-self-priming pump evacuator, be located between liquid container and self-priming pump, comprise airtight compensating groove, described airtight compensating groove is provided with the compensating groove liquid outlet being connected on white sucking pump liquid entering hole, on described airtight compensating groove, be also provided with the compensating groove liquid entering hole that is connected to liquid container, in described airtight compensating groove, liquid be housed.
As preferred technological scheme, described compensating groove liquid outlet is higher than described self-priming pump liquid entering hole.
Owing to having adopted technique scheme, anti-self-priming pump evacuator, be located between liquid container and self-priming pump, comprise airtight compensating groove, described airtight compensating groove is provided with the compensating groove liquid outlet being connected on self-priming pump liquid entering hole, on described airtight compensating groove, be also provided with the compensating groove liquid entering hole that is connected to liquid container, in described airtight compensating groove, liquid be housed.When self-priming pump starts, liquid will soon be full of the pump housing, and the interior minimizing due to liquid of airtight compensating groove, will form micro-vacuum state, and then the liquid material being installed in the liquid container of below ground is attracted up, input in the pump housing endlessly, thereby the generation of having avoided the pump housing to find time has guaranteed the safe handling of equipment.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention;
In figure: 1-liquid container; 2-self-priming pump; The airtight compensating groove of 3-; 4-compensating groove liquid outlet; 5-compensating groove liquid entering hole; 6-self-priming pump liquid entering hole.
Embodiment
As shown in Figure 1, anti-self-priming pump evacuator, be located between liquid container 1 and self-priming pump 2, comprise airtight compensating groove 3, described airtight compensating groove 3 is provided with the compensating groove liquid outlet 4 being connected on self-priming pump liquid entering hole 6, on described airtight compensating groove 3, be also provided with the compensating groove liquid entering hole 5 that is connected to liquid container 1, in described airtight compensating groove 3, liquid be housed, interior the filled liquid of described airtight compensating groove 3 is identical with interior the filled liquid of described liquid container 1.
Described compensating groove liquid outlet 4 is higher than described self-priming pump liquid entering hole 6.
When self-priming pump starts, liquid will soon be full of the pump housing, and the interior minimizing due to liquid of airtight compensating groove 3, will form micro-vacuum state, and then the liquid material being installed in the liquid container of below ground is attracted up, input in the pump housing endlessly, thereby the generation of having avoided the pump housing to find time has guaranteed the safe handling of equipment.
More than show and described basic principle of the present invention, major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
Claims (2)
1. anti-self-priming pump evacuator, be located between liquid container and self-priming pump, it is characterized in that: comprise airtight compensating groove, described airtight compensating groove is provided with the compensating groove liquid outlet being connected on self-priming pump liquid entering hole, on described airtight compensating groove, be also provided with the compensating groove liquid entering hole that is connected to liquid container, in described airtight compensating groove, liquid be housed.
2. anti-self-priming pump evacuator as claimed in claim 1, is characterized in that: described compensating groove liquid outlet is higher than described self-priming pump liquid entering hole.
